8 tips for eating well

These practical tips can help you make healthier choices. The two keys to a healthy diet are eating the right amount of food for how active you are and eating a range of foods to make sure you're getting a balanced diet.

A healthy balanced diet contains a variety of types of food, including lots of fruit, vegetables and starchy foods such as wholemeal bread and wholegrain cereals; some protein-rich foods such as meat, fish, eggs and lentils; and some milk and dairy foods.

1. Base your meals on starchy foods

Starchy foods such as bread, cereals, rice, pasta and potatoes are a really important part of a healthy diet. Try to choose wholegrain varieties of starchy foods whenever you can.

Starchy foods should make up about a third of the food we eat. They are a good source of energy and the main source of a range of nutrients in our diet. As well as starch, these foods contain fibre, calcium, iron and B vitamins.

Most of us should eat more starchy foods - try to include at least one starchy food with each of your main meals. So you could start the day with a wholegrain breakfast cereal, have a sandwich for lunch, and potatoes, pasta or rice with your evening meal.

Some people think starchy foods are fattening, but gram for gram they contain less than half the calories of fat. You just need to watch the fats you add when cooking and serving these foods, because this is what increases the calorie content.

Why choose wholegrain foods?

Wholegrain foods contain more fibre and other nutrients than white or refined starchy foods.
We also digest wholegrain foods more slowly so they can help make us feel full for longer.
Wholegrain foods include :

• Wholemeal and wholegrain bread, pitta and chapatti
• Wholewheat pasta and brown rice
• Wholegrain breakfast cereals

2. Eat lots of fruit and veg

Most people know we should be eating more fruit and veg. But most of us still aren't eating enough.

Try to eat at least 5 portions of a variety of fruit and veg every day. It might be easier than you think.

You could try adding up your portions during the day.

For example, you could have:

• a glass of juice and a sliced banana with your cereal at breakfast
• a side salad at lunch
• a pear as an afternoon snack
• a portion of peas or other vegetables with your evening meal

You can choose from fresh, frozen, tinned, dried or juiced, but remember potatoes count as a starchy food, not as portions of fruit and veg.

Most of us should be eating more fish - including a portion of oily fish each week. It's an excellent source of protein and contains many vitamins and minerals.

Aim for at least two portions of fish a week, including a portion of oily fish. You can choose from fresh, frozen or canned - but remember that canned and smoked fish can be high in salt.

What are oily fish?

Some fish are called oily fish because they are rich in certain types of fats, called omega 3 fatty acids, which can help keep our hearts healthy.

How much oily fish?

Although most of us should be eating more oily fish, women who might have a baby one day should have a maximum of 2 portions of oily fish a week (a portion is about 140g). And 4 is the recommended maximum number of portions for other adults.
Examples of oily fish
Salmon, mackerel, trout, herring, fresh tuna, sardines, pilchards, eel

Examples of white or non-oily fish
Cod, haddock, plaice, coley, tinned tuna, skate, hake

Shark, swordfish and marlin
Don't have more than one portion a week of these types of fish. This is because of the high levels of mercury in these fish.

Anyone who regularly eats a lot of fish should try and choose as wide a variety as possible.

To stay healthy we need some fat in our diets. What is important is the kind of fat we are eating. There are two main types of fat:

• saturated fat - having too much can increase the amount of cholesterol in the blood, which increases the chance of developing heart disease
• unsaturated fat - having unsaturated fat instead of saturated fat lowers blood cholesterol

Try to cut down on food that is high in saturated fat and have foods that are rich in unsaturated fat instead, such as vegetable oils (including sunflower, rapeseed and olive oil), oily fish, avocados, nuts and seeds.

4. Cut down on saturated fat and sugar Fats

Foods high in saturated fat

Try to eat these sorts of foods less often or in small amounts:

• meat pies, sausages, meat with visible white fat
• hard cheese
• butter and lard
• pastry
• cakes and biscuits
• cream, soured cream and crème fraîche
• coconut oil, coconut cream or palm oil

For a healthy choice, use just a small amount of vegetable oil or a reduced-fat spread instead of butter, lard or ghee. And when you are having meat, try to choose lean cuts and cut off any visible fat.

How do I know if a food is high in fat?

Look at the label to see how much fat a food contains. Generally the label will say how many grams (g) of fat there are in 100g of the food.

Some foods also give a figure for saturated fat, or 'saturates'.

Use the following as a guide to work out if a food is high or low in fat.

Total fat - what's high and what's low?

High is more than 20g fat per 100g
Low is 3g fat or less per 100g

If the amount of fat per 100g is in between these figures, then that is a medium level of fat.

Saturated fat - what's high and what's low?

High is more than 5g saturates per 100g
Low is 1.5g saturates or less per 100g

If the amount of saturates per 100g is in between these figures, then that is a medium level of saturated fat.

Remember that the amount you eat of a particular food affects how much fat you will get from it.
Try to choose more foods that are low in fat and cut down on foods that are high in fat.

5. Sugar

Most people in the UK are eating too much sugar. We should all be trying to eat fewer foods containing added sugar, such as sweets, cakes and biscuits, and drinking fewer sugary soft and fizzy drinks.

Having sugary foods and drinks too often can cause tooth decay, especially if you have them between meals. Many foods that contain added sugar can also be high in calories so cutting down could help you control your weight.

How do I know if a food is high in added sugar?

Take a look at the label. The ingredients list always starts with the biggest ingredient first.

But watch out for other words used to describe added sugars, such as sucrose, glucose, fructose, maltose, hydrolysed starch and invert sugar, corn syrup and honey. If you see one of these near the top of the list, you know the food is likely to be high in added sugars.

Another way to get an idea of how much sugar is in a food is to have a look for the 'Carbohydrates (of which sugars)' figure on the label. But this figure can't tell you how much is from added sugars, which is the type we should try to cut down on.

High is more than 15g sugars per 100g
Low is 5g sugars or less per 100g

If the amount of sugars per 100g is in between these figures, then that is a medium level of sugars.

Remember that the amount you eat of a particular food affects how much sugars you will get from it.

Sometimes you will only see a figure for total 'Carbohydrates', not for 'Carbohydrates (of which sugars)', which means the figure also includes the carbohydrate from starchy foods.

5. Try to eat less salt - no more than 6g a day

Lots of people think they don't eat much salt, especially if they don't add it to their food. But don't be so sure!

Every day in the UK, 85% men and 69% women eat too much salt. Adults - and children over 11 - should have no more than 6g salt a day. Younger children should have even less.

Three-quarters (75%) of the salt we eat is already in the food we buy, such as breakfast cereals, soups, sauces and ready meals. So you could easily be eating too much salt without realising it.

Eating too much salt can raise your blood pressure. And people with high blood pressure are three times more likely to develop heart disease or have a stroke than people with normal blood pressure.

How do I know if a food is high in salt?

Check the label to find out the figure for salt per 100g.

High is more than 1.5g salt per 100g (or 0.6g sodium)
Low is 0.3g salt or less per 100g (or 0.1g sodium)

If the amount of salt per 100g is in between these figures, then that is a medium level of salt.

Remember that the amount you eat of a particular food affects how much salt you will get from it.

6. Get active and try to be a healthy weight

It's not a good idea to be either underweight or overweight. Being overweight can lead to health conditions such as heart disease, high blood pressure or diabetes. Being underweight could also affect your health.

Check if you are the right weight for your height using the link below.
If you're worried about your weight, ask your GP or a dietitian for advice. But if you think you just need to lose a little weight, the main things to remember are:

• only eat as much food as you need
• make healthy choices - it's a good idea to choose low-fat and low-sugar varieties, eat plenty of fruit and veg and wholegrains
• get more active

It's also important to eat a variety of types of food so you get all the nutrients your body needs.
Physical activity is a good way of using up extra calories, and helps control our weight. But this doesn't mean you need to join a gym.
Just try to get active every day and build up the amount you do. For example, you could try to fit in as much walking as you can into your daily routine. Try to walk at a good pace.
Whenever we eat more than our body needs, we put on weight. This is because we store any energy we don't use up - usually as fat. Even small amounts of extra energy each day can lead to weight gain.

But crash diets aren't good for your health and they don't work in the longer term. The way to reach a healthy weight - and stay there - is to change your lifestyle gradually. Aim to lose about 0.5 to 1kg (about 1 to 2lbs) a week, until you reach a healthy weight for your height.

7. Drink plenty of water

We should be drinking about 6 to 8 glasses (1.2 litres) of water, or other fluids, every day to stop us getting dehydrated.

When the weather is warm or when we get active, our bodies need more than this. But avoid drinking soft and fizzy drinks that are high in added sugar.

Alcohol

There is nothing wrong with the occasional drink. But drinking too much can cause problems. Alcohol is also high in calories, so cutting down could help you control your weight.

Women can drink up to 2 to 3 units of alcohol a day and men up to 3 to 4 units a day, without significant risk to their health.

A unit is half a pint of standard strength (3 to 5% ABV) beer, lager or cider, or a pub measure of spirit. A glass of wine is about 2 units and alcopops are about 1.5 units.

For good health, it's a good idea to spread your drinking throughout the week and avoid binge drinking. Drinking heavily over a long period of time can damage the liver.

8. Don't skip breakfast

Breakfast can help give us the energy we need to face the day, as well as some of the vitamins and minerals we need for good health.

Some people skip breakfast because they think it will help them lose weight. But missing meals doesn't help us lose weight and it isn't good for us, because we can miss out on essential nutrients.

There is some evidence to suggest that eating breakfast can actually help people control their weight.

So why not go for a bowl of wholegrain cereal with some low-fat milk and sliced banana and a glass of fruit juice for a healthy start to the day?

The Food Guide

The Food Guide Pyramid is one way for people to understand how to eat healthy. A rainbow of colored, vertical stripes represents the five food groups plus fats and oils. Here's what the colors stand for:


* Brown — grains
* green — vegetables
* red — fruits
* yellow — fats and oils
* blue — milk and dairy products
* purple — meat, beans, fish, and nuts

The U.S. Department of Agriculture (USDA) changed the pyramid in 2005 because they wanted to do a better job of telling Americans how to be healthy. The agency later released a special version for kids. Notice the girl climbing the staircase up the side of the pyramid? That's a way of showing kids how important it is to exercise and be active every day. In other words, play a lot! The steps are also a way of saying that you can make changes little by little to be healthier. One step at a time, get it?
The Pyramid Speaks

Let's look at some of the other messages this new symbol is trying to send:

Eat a variety of foods. A balanced diet is one that includes all the food groups. In other words, have foods from every color, every day.

Eat less of some foods, and more of others. You can see that the bands for meat and protein (purple) and oils (yellow) are skinnier than the others. That's because you need less of those kinds of foods than you do of fruits, vegetables, grains, and dairy foods.

You also can see the bands start out wider and get thinner as they approach the top. That's designed to show you that not all foods are created equal, even within a healthy food group like fruit. For instance, apple pie would be in that thin part of the fruit band because it has a lot of added sugar and fat. A whole apple — crunch! — would be down in the wide part because you can eat more of those within a healthy diet.

Make it personal. Through the USDA's MyPyramid website, people can get personalized recommendations about the mix of foods they need to eat and how much they should be eating. There is a kids' version of the website available too.
How Much Do I Need to Eat?

Everyone wants to know how much they should eat to stay healthy. It's a tricky question, though. It depends on your age, whether you're a girl or a boy, and how active you are. Kids who are more active burn more calories, so they need more calories. But we can give you some estimates for how much you need of each food group.

Grains
Grains are measured out in ounce equivalents. What the heck are they? Ounce equivalents are just another way of showing a serving size.
Here are ounce equivalents for common grain foods. An ounce equivalent equals:

* 1 slice of bread
* ½ cup of cooked cereal, like oatmeal
* ½ cup of rice or pasta
* 1 cup of cold cereal

* 4- to 8-year-olds need 4–5 ounce equivalents each day.
* 9- to 13-year-old girls need 5 ounce equivalents each day.
* 9- to 13-year-old boys need 6 ounce equivalents each day.
And one last thing about grains: Try make at least half of your grain servings whole grains, such as 100% whole-wheat bread, brown rice, and oatmeal.

Vegetables
Of course, you need your vegetables, especially those dark green and orange ones. But how much is enough? Vegetable servings are measured in cups.

* 4- to 8-year-olds need 1½ cups of veggies each day.
* 9- to 13-year-old girls need 2 cups of veggies each day.
* 9- to 13-year-old boys need 2½ cups of veggies each day.

Fruits
Sweet, juicy fruit is definitely part of a healthy diet. Here's how much you need:

* 4- to 8-year-olds need 1–1½ cups of fruit each day.
* 9- to 13-year-olds need 1½ cups of fruit each day.

Milk and Other Calcium-Rich Foods
Calcium builds strong bones to last a lifetime, so you need these foods in your diet.

* 4- to 8-year-olds need 2 cups of milk (or another calcium-rich food) each day.
* 9- to 13-year-olds need 3 cups of milk (or another calcium-rich food) each day.
If you want something other than milk, you can substitute yogurt, cheese, or calcium-fortified orange juice — just to name a few.

Meats, Beans, Fish, and Nuts
These foods contain iron and lots of other important nutrients. Like grains, these foods are measured in ounce equivalents.
An ounce equivalent of this group would be:

* 1 ounce of meat, poultry, or fish
* ¼ cup cooked dry beans
* 1 egg
* 1 tablespoon of peanut butter
* ½ ounce (about a small handful) of nuts or seeds

* 4- to 8-year-olds need 3–4 ounce equivalents each day.
* 9- to 13-year-olds need 5 ounce equivalents each day.

Whoa! That's a lot to swallow. The good news is that your mom, dad, and the other grown-ups in your life will help you eat what you need to stay healthy. There's more good news — you don't have to become a perfect eater overnight. Just remember those stairs climbing up the side of the new pyramid and take it one step at a time.

Know your Fats

Knowing which fats raise LDL cholesterol and which ones don't is the first step in lowering your risk of heart disease. In addition to the LDL produced naturally by your body, saturated fat, trans-fatty acids and dietary cholesterol can also raise blood cholesterol. Monounsaturated fats and polyunsaturated fats appear to not raise LDL cholesterol; some studies suggest they might even help lower LDL cholesterol slightly when eaten as part of a low-saturated and trans-fat diet.

The American Heart Association's Nutrition Committee strongly advises these fat guidelines for healthy Americans over age 2:

* Limit total fat intake to less than 25–35 percent of your total calories each
day;
* Limit saturated fat intake to less than 7 percent of total daily calories;
* Limit trans fat intake to less than 1 percent of total daily calories;
* The remaining fat should come from sources of monounsaturated and polyunsaturated fats such as nuts, seeds, fish and vegetable oils; and
* Limit cholesterol intake to less than 300 mg per day, for most people. If you have coronary heart disease or your LDL cholesterol level is 100 mg/dL or greater, limit your cholesterol intake to less than 200 milligrams a day.

For example, a sedentary female who is 31–50 years old needs about 2,000 calories each day. Therefore, she should consume less than 16 g saturated fat, less than 2 g trans fat and between 50 and 70 grams of total fat each day (with most fats coming from sources of polyunsaturated and monounsaturated fats, such as fish, nuts, seeds and vegetable oils).

Saturated fat
Saturated fat is the main dietary cause of high blood cholesterol. Saturated fat is found mostly in foods from animals and some plants. Foods from animals include beef, beef fat, veal, lamb, pork, lard, poultry fat, butter, cream, milk, cheeses and other dairy products made from whole and 2 percent milk. All of these foods also contain dietary cholesterol. Foods from plants that contain saturated fat include coconut, coconut oil, palm oil and palm kernel oil (often called tropical oils), and cocoa butter.

Hydrogenated fat
During food processing, fats may undergo a chemical process called hydrogenation. This is common in margarine and shortening. These fats also raise blood cholesterol. The saturated fat content of margarines and spreads is printed on the package or Nutrition Facts label.

Polyunsaturated and monounsaturated fats
Polyunsaturated and monounsaturated fats are the two unsaturated fats. They're found mainly in many fish, nuts, seeds and oils from plants. Some examples of foods that contain these fats include salmon, trout, herring, avocados, olives, walnuts and liquid vegetable oils such as soybean, corn, safflower, canola, olive and sunflower.

Both polyunsaturated and monounsaturated fats may help lower your blood cholesterol level when you use them in place of saturated and trans fats. But a moderate intake of all types of fat is best. Keep total fat intake between 25 and 35 percent of calories, with most fats coming from sources of polyunsaturated and monounsaturated fatty acids such as fish, nuts and vegetable oils.

Trans-fatty Acids and Hydrogenated Fats
Unsaturated fatty acids can be in one of two shapes — "cis" and "trans." These terms refer to the physical positioning of hydrogen atoms around the carbon chain. The cis form is more common than the trans form. Trans-fatty acids (TFA) are found in small amounts in various animal products such as beef, pork, lamb and the butterfat in butter and milk.

TFA are also formed during the process of hydrogenation, making margarine, shortening, cooking oils and the foods made from them a major source of TFA in the American diet. Partially hydrogenated vegetable oils provide about three-fourths of the TFA in the U.S. diet. The trans fat content of foods is printed on the package of the Nutrition Facts label. Keep trans fat intake to less than 1 percent of total calories. For example, if you need 2,000 calories a day, you should consume less than 2 grams of trans fat.

Trans-fatty acids are also formed during the process of hydrogenation. "Hydrogenate" means to add hydrogen. When unsaturated fatty acids are hydrogenated, some of the hydrogen atoms are added on opposite sides of the molecule to the already attached hydrogen. Cis double bonds convert to trans double bonds, and the fatty acids become saturated.

How are trans-fatty acids harmful?
In clinical studies, TFA or hydrogenated fats tended to raise total blood cholesterol levels. Some scientists believe they raise cholesterol levels more than saturated fats. TFA also tend to raise LDL (bad) cholesterol and lower HDL (good) cholesterol when used instead of cis fatty acids or natural oils. These changes may increase the risk of heart disease.

Because there are no standard methods, it's difficult to estimate the TFA content of food items. It's also difficult to estimate intake, especially long-term intake. The four most important sources of TFA in one large group of women studied included margarine; beef, pork or lamb as the main dish; cookies (biscuits); and white bread.

As of January 2006, the FDA requires trans fat to be listed on the nutrition label. Although changes in labeling are important, they aren't enough. Many fast foods contain high levels of TFA. There are no labeling regulations for fast food, and it can even be advertised as cholesterol-free and cooked in vegetable oil. Eating one doughnut at breakfast (3.2 g of TFA) and a large order of french fries at lunch (6.8 g of TFA) add 10 grams of TFA to one's diet, so the lack of regulations for labeling restaurant foods can be harmful to your health.

Is butter better than margarine?
Recent studies on the potential cholesterol-raising effects of TFA have raised public concern about the use of margarine and whether other options, including butter, might be a better choice. Some stick margarines contribute more TFA than unhydrogenated oils or other fats.

Because butter is rich in both saturated fat and cholesterol, it's potentially a highly atherogenic food (a food that causes the arteries to be blocked). Most margarine is made from vegetable fat and provides no dietary cholesterol. The more liquid the margarine, i.e., tub or liquid forms, the less hydrogenated it is and the less TFA it contains.

Regulating your intake of trans-fatty acids
The American Heart Association's Nutrition Committee strongly advises that healthy Americans over age 2 limit their intake of trans fat to less than 1 percent of total calories.

Based on current data, the American Heart Association recommends that consumers follow these tips:

* Choose a diet rich in fruits, vegetables, whole-grain, high-fiber foods, and fat-free and low-fat dairy most often.
* Keep total fat intake between 25 and 35 percent of calories, with most fats coming from sources of monounsaturated and polyunsaturated fats such as fish, nuts, seeds and vegetable oils most often.
* Use naturally occurring, unhydrogenated vegetable oils such as canola, safflower, sunflower or olive oil most often.
* Look for processed foods made with unhydrogenated oil rather than partially
hydrogenated or hydrogenated vegetable oils or saturated fat.
* Use soft margarine as a substitute for butter, and choose soft margarines
(liquid or tub varieties) over harder stick forms. Look for ”0 g trans fat” on
the Nutrition Facts label.
* French fries, doughnuts, cookies, crackers, muffins, pies and cakes are
examples of foods that are high in trans fat. Don't eat them often.
* Limit the saturated fat in your diet. If you don't eat a lot of saturated fat,
you won't be consuming a lot of trans fat.
* Limit commercially fried foods and baked goods made with shortening or
partially hydrogenated vegetable oils. Not only are these foods very high in
fat, but that fat is also likely to be very hydrogenated, meaning a lot of
trans fat.
* Limited fried fast food. Commercial shortening and deep-frying fats will
continue to be made by hydrogenation and will contain saturated fat and
trans fat.

Eat a Heart - stay Fit

Eat a Heart-Healthy Diet

Some cholesterol is made by your body. The food you eat is responsible for the rest. Food products from animals contain cholesterol — including meats, poultry, shellfish, eggs, butter, cheese and whole or 2 percent milk. And any type of food can also contain saturated fats and trans fats, which cause your body to make more cholesterol.

The American Heart Association recommends that you keep your intake of total fat to between 25 percent and 35 percent, your saturated fat consumption to less than 7 percent and your intake of trans fat to less than 1 percent of your total daily calories.

At the same time, limit your intake of cholesterol from food to less than 300 mg per day. People with high LDL (bad) blood cholesterol levels or who are taking cholesterol medication should consume less than 200 mg of cholesterol per day.

Eat at least 25 to 30 grams of dietary fiber each day — preferably from whole grains, fruits, vegetables and legumes.

To combat high blood pressure and for overall cardiovascular health, limit sodium to 2,300 mg or less per day. Some people — African Americans, middle-aged and older adults, and people with high blood pressure — need less than 1,500 mg per day. And if you drink alcohol, do so in moderation (no more than one drink a day for women, no more than two for men).

But a heart-healthy diet isn't just about what you shouldn't eat. It also means eating a diet rich in vegetables and fruits, with whole grains, high-fiber foods, lean meats and poultry, fish at least twice a week, and fat-free or 1 percent fat dairy products. Also, the diet should be low in saturated fat, trans fat and cholesterol.

By learning to make smart choices — whether you're cooking at home or eating out — you can enjoy flavorful foods while you manage your cholesterol.

To Health and Longevity

Eating is one the most important events in everyone’s life. We enjoy eating - it’s part of who we are and part of our culture; in fact, eating is the hottest universal topic of all times. We depend on eating: the foods we eat are the sole source of our energy and nutrition. We know so much about eating: we are born with the desire to eat and grown up with rich traditions of eating. But we also know so little about eating - about how the foods we eat everyday affect our health. We are more confused than ever about the link between diet and health: margarine is healthier than butter or not; dietary vitamin antioxidants can prevent lung cancer or can not. Eating is a paradox and a mystery that our ancestors tried and modern scientists are trying to solve.

Based on experiences and traditions, our ancestors have used foods and plant materials to treat various kinds of illness. Manuscripts discovered from a tomb (dated 168 B.C.) in China described prescriptions for 52 ailments with herbs, grains, legumes, vegetables, animal parts, and minerals. Ancient Sumerians recorded the use of 250 medicinal plants on tablets five thousand years ago. Today, plant and food remedies are still the major medicinal source for 80% of the world’s population.

The pharmacological roles of everyday foods have long been neglected by modern medicine due to lack of proven scientific validity. The main focus of modern medicine has been on pharmaceuticals. With the invention of modern chemotherapy by in the early twentieth century and sulfa drugs and antibiotics in the 1930’s and 1940’s, it seemed as if chemical medicines would take care of all our ills. However, while there continues to be great strides made in the understanding and use of pharmaceuticals, there is also widespread dissatisfaction with both them and the system of medicine that utilizes them. This dissatisfaction is centered around the feeling that they are too disease-oriented, and perhaps too limited by their precision to cope effectively with the subtle factors and interrelationships that compromise human health and disease. The precise and pure nature of modern biomedical pharmaceuticals also tends to increase their side effects. In addition, with the victory over many common infectious diseases, more people are concerned with chronic degenerative processes and with prevention of disease. The increasing concerns have started a new movement in medical research. More and more mainstream scientists are reaching back to the truth of ancient food folk medicines and dietary practices for clues to remedies and antidotes to our modern diseases.

Research on pharmacological effects of foods is fast-paced and the results are exciting. The mystery of what foods can do for or to us has started to unveil. In order to effectively use foods for our health benefits, the following issues need to be considered:

* Keep up with the most recent scientific findings and make use of them for our health benefits
* Try to use variety of whole foods as much as possible instead of isolated dietary supplements for your health problems - they are safer, cheaper, and usually more effective since they can provide multiple and balanced disease fighting capabilities
* Choice of foods is important: certain foods may need to be avoided due to their disease encouraging activities
* How do you prepare and eat your foods can affect their pharmacological effects
* Concerns about multiple health conditions: foods that benefit one health condition may be harmful to others
* Overall nutritional values of foods

Eat for a killer immunity

8 resistance-boosting foods and ingredients to help you win the cold war
It takes more than an apple a day to keep viruses at bay. You can improve your body’s resistance by getting your seven servings of fruits and veggies and 8 to 10 glasses of water a day, at the very least.These particular immune system-boosting foods and ingredients can keep you in fighting condition.

Yogurt

The "live active cultures" found in yogurt, are healthy bacteria that keep the gut and intestinal tract free of disease-causing germs. Although they're available in supplement form, a study from the University of Vienna in Austria found that a daily 7-ounce dose of yogurt was just as effective in boosting immunity as popping pills.

In an 80-day Swedish study of 181 factory employees, those who drank a daily supplement of Lactobacillus reuteri — a specific probiotic that appears to stimulate white blood cells — took 33 percent fewer sick days than those given a placebo. Any yogurt with a live and active cultures seal contains some beneficial bugs, but Stonyfield Farm is the only U.S. brand that contains this specific strain. Have two 6-ounce servings a day.

Be sure you chose a yogurt that is no more than 200 calories, 4 grams of fat or less, 30 g of sugar or less and at least 6 grams of protein.

Sweet potatoes
You may not think of skin as part of your immune system. But this crucial organ, covering an impressive 16 square feet, serves as a first-line fortress against bacteria, viruses, and other undesirables. To stay strong and healthy, your skin needs vitamin A. "Vitamin A plays a major role in the production of connective tissue, a key component of skin," explains Dr. David Katz, director of the Yale-Griffin Prevention Research Center in Derby, Conn.

One of the best ways to get vitamin A into your diet is from foods containing beta-carotene, which your body turns into vitamin A. One of the quickest, most delicious ways to get beta-carotene? Serve candied sweet potatoes (canned are fine). Each 12-cup serving delivers only 170 calories but 40 percent of the daily recommendation of vitamin A as beta-carotene. They're so good, you might want to save them for dessert! Think orange when looking for other foods rich in beta-carotene: carrots, squash, canned pumpkin and cantaloupe.

Tea
this winter, and you may just get through it without a sniffle. Immunologists at Harvard University discovered that people who drank five cups of black tea a day for 2 weeks transformed their immune system T cells into "Hulk cells" that pumped out 10 times more cold and flu virus-fighting interferon — proteins that defend against infection — than did the immune systems of those who didn't drink black tea. Green tea should work just as well.

"Not just the common cold and flu, but food poisoning, infected cuts, athlete's foot — even diseases such as tuberculosis and malaria — are caused by germs that your body fights with interferon. We think the interferon boosts from tea may help prevent or lessen the severity of all these conditions," says Dr. Jack Bukowski.

While five cups a day may seem like a lot, he thinks fewer cups may still offer some valuable protection. "And the interferon link may explain tea's other health benefits, including its reported cancer-fighting power, since we already know that interferon slows the growth of tumor cells," he says.

Chicken soup

When University of Nebraska researchers tested 13 brands, they found that all but one (chicken-flavored ramen noodles) blocked the migration of inflammatory white cells — an important finding, because cold symptoms are a response to the cells' accumulation in the bronchial tubes.
The amino acid cysteine, released from chicken during cooking, chemically resembles the bronchitis drug acetylcysteine, which may explain the results. The soup's salty broth keeps mucus thin the same way cough medicines do.

Added spices, such as garlic and onions, can increase soup's immune-boosting power. Have a bowl when feeling crummy.

Beef

Zinc deficiency is one of the most common nutritional shortfalls among American adults, especially for vegetarians and those who've cut back on beef, a prime source of this immunity-bolstering mineral. And that's unfortunate, because even mild zinc deficiency can increase your risk of infection. Zinc in your diet is very important for the development of white blood cells, the intrepid immune system cells that recognize and destroy invading bacteria, viruses, and assorted other bad guys, explains William Boisvert, Ph.D., an expert in nutrition and immunity at The Scripps Research Institute in La Jolla, Calif.

A 3-oz serving of lean beef (enough to make a respectable, but not decadent, roast beef sandwich) provides about 30 percent of the daily value for zinc. That's often enough to make the difference between deficient and sufficient. Just can't stomach beef? Try zinc-rich oysters, fortified cereals, pork, poultry, yogurt, or milk.

Mushrooms

For centuries, people around the world have turned to mushrooms for a healthy immune system. Contemporary researchers now know why. "Studies show that mushrooms increase the production and activity of white blood cells, making them more aggressive. This is a good thing when you have an infection," says Douglas Schar, director of the Institute of Herbal Medicine in Washington, D.C.


Shiitake and maitake mushrooms, now available fresh in U.S. supermarkets, appear to pack the biggest immunity punch. They're easy to use too. Just add a handful to pasta sauce, saute with a little oil and add to eggs, or heap triple-decker style on a frozen pizza. Good news for absent-minded chefs: "Basically, you can burn them, and they will still powerfully stimulate the immune system" says Schar.

Fish and shellfish

Getting adequate selenium (plentiful in foods like oysters, lobsters, crabs, and clams) increased immune cell production of proteins called cytokines in a British study of 22 adults. The scientists say that cytokines help clear flu viruses out of your body.


Of all fats, omega-3s--found in fish such as Pacific salmon--created the highest blood levels of flu-fighting T cells and interferon-gamma cytokines in a British study of 150 people.

Garlic

Garlic contains the active ingredient allicin, which fights infection and bacteria. British researchers gave 146 people either a placebo or a garlic extract for 12 weeks; the garlic takers were two-thirds less likely to catch a cold. Other studies suggest that garlic lovers who chow more than six cloves a week have a 30 percent lower rate of colorectal cancer and a 50 percent lower rate of stomach cancer. Two raw cloves a day and add crushed garlic to your cooking several times a week.

Food combos add up to healthier eating

Simple pairings have benefits, from stronger bones to better eyesight
Healthy eating is all about math: subtracting fat, counting calories, dividing portions.

But let's not forget adding: It's the little things we toss in the pot that often yield the biggest benefits. "Adding just one food to another can make a tremendous difference in your total nutrient intake and offer significant health gains," says Tara Gidus, RD, a spokesperson for the American Dietetic Association.

With benefits ranging from stronger bones and better eyesight to a healthier heart and improved immunity, here are 15 of our favorite quick pairings for breakfast, lunch, dinner, snacks — even beverages — that taste great, take seconds to make, and add up to amazing health.

Whole grain cereal (any kind) + sunflower seeds for better immunity
Sprinkling ½ cup of sunflower seeds into your morning cereal provides more than 100 percent of your day's requirements for alpha-tocopherol, the most active form of vitamin E. As an antioxidant, vitamin E protects cells from damage caused by destructive free radicals that can lead to cancer and cardiovascular disease.

Scrambled eggs + red peppers for smoother skin
Tossing in ½ cup of chopped red peppers delivers more than 100 percent of your daily vitamin C need — which spells good news for your skin. Researchers in the United Kingdom looked at vitamin C intake in 4,025 women and found that those who ate more vitamin C had less wrinkling and dryness.

Smoothie (any kind) + wheat germ for faster healing of cuts and bruises
One-quarter cup of wheat germ packs nearly half of your day's requirements for zinc, an essential mineral that helps repair cells and strengthens the immune system. Even a slight deficiency can reduce your immunity, making it harder to heal.

Sandwich (any kind) + spinach leaves for decreased risk of night blindness
Stacking only three small leaves of spinach on your sandwich satisfies at least 20 percent of your day's vitamin A requirements. Vitamin A helps you see in the dark, but it also protects your eyes from age-related macular degeneration, which can lead to vision loss.

Garden salad + canned wild salmon for healthier brain and heart

Adding 3 ounces of canned wild salmon to your salad provides half of the weekly recommendation for healthy omega-3 fats. The fatty acids found in canned salmon are linked with improvements in heart and brain health. Choosing wild lowers your exposure to dioxin, which is a cancer-causing contaminant found in the feed given to the farm-raised variety, says Evelyn Tribole, RD, author of "The Ultimate Omega-3 Diet."

Stir-fry (any kind) + kale for stronger eyes

One-half cup of kale delivers at least 12 mg of lutein and zeaxanthin, carotenoids found in dark leafy greens that help combat cataracts and age-related macular degeneration. Results from the Eye Disease Case Control Study found that people who ate the most of these nutrients — as much as 5.8 mg a day — had a significantly lower risk of AMD than those who ate the least. Stir-fry is the perfect way to throw it into the mix; if you're not a kale fan, other leafy greens such as Swiss chard and spinach offer similar benefits.

Salsa + chickpeas for lower body weight
Adding chickpeas to a light dip like salsa adds bulk without lots of calories and boosts your intake of protein, so you fill up faster and feel fuller. Eating chickpeas regularly may also improve your overall food choices. An Australian study published in the Journal of the American Dietetic Association found that people who ate ½ cup of chickpeas a day weighed a pound less and ate less food overall.

Low-fat pudding + nonfat powdered milk for less PMS
Sprinkling 1/3 cup of nonfat powdered milk into pudding satisfies 40 percent of your day's calcium and 50 percent to 100 percent of your vitamin D requirements, depending on your age. Research shows that the combination of calcium and vitamin D reduces the risk of developing PMS.

Green tea + lemon for lower cancer risk
Green tea is already rich in antioxidants, but a study from Purdue University found that adding citrus juice led to a fourfold increase in disease-fighting catechins. Lemon juice in particular preserved the most catechins, while orange, lime, and grapefruit juices were less potent but effective.

Water + unsweetened cranberry juice for fewer cavities
Unsweetened cranberry juice prevents the buildup of Streptococcus mutans, the bacteria behind most cavities, by preventing them from sticking to the tooth's surface. The unsweetened juice also interferes with plaque formation. Mixing it with water helps dilute the juice's tartness.

Strawberries + nonfat Greek yogurt for more muscle
Greek yogurt packs twice the protein of ordinary yogurt, and protein is essential for building, repairing, and maintaining muscles, which burn more calories than fat. Strawberries add a burst of natural sweetness.

Pasta (any kind) + parsley for stronger bones

Topping a pasta dish with just six sprigs of parsley offers a fresh boost of flavor and delivers a full day's supply of vitamin K, says Marisa Moore, RD, an Atlanta-based nutritionist and ADA spokesperson. Vitamin K is important for bone health — studies show that it helps prevent fractures and may guard against bone loss.

Burger + ketchup for decreased cancer risk

A tablespoon of this condiment supplies you a healthful dose of lycopene, an antioxidant that guards against various forms of cancer by blocking cell-damaging free radicals. Eating processed tomatoes (such as those in ketchup and tomato sauce) is best; cooking releases lycopene inside the plant cells, making it easier to digest and absorb, reports Steven J. Schwartz, PhD, professor of food science at Ohio State University.
