By this time of year everyone seems to be worried about getting a cold, the flu or worse.

The question becomes what can you do to improve your immunity. Things that can boost your immunity include better stress management, exercise, getting adequate sleep, and proper nutrition.

The good news is you don't need a fancy exercise program—walking fits the bill. Try to get your heart rate up for at least 20 minutes three or more days a week. Getting adequate sleep is also important. Aim for at least seven hours a night. Having close relationships and a strong support system helps with stress management. In addition to these things, your diet plays a role in immunity. In fact, proper nutrition is essential for your immune system to work well.

To improve your immune system, eat more fruits and vegetables. All fruits and vegetables are good, although some are higher in antioxidants than others which can boost your resistance to infections. Colorful fruits and vegetables are especially high in antioxidants. Think red, orange, yellow, purple and blue.

For foods that boost your immunity, focus on foods containing the three major antioxidant vitamins, vitamin C, vitamin E and beta-carotene.

Vitamin C is found in: berries, broccoli, Brussel sprouts, cantaloupe, cauliflower, grapefruit, honeydew, kale, kiwi, mango, nectarine, orange, papaya, snow peas, sweet potato, strawberries, tomatoes, and red, green and yellow peppers.

Vitamin E is found in: broccoli (boiled), avocado, chard, mustard and turnip greens, mangoes, nuts, papaya, pumpkin, red peppers, spinach (boiled) and sunflower seeds.

Beta carotene (and other carotenoids) is found in: apricots, asparagus, beets, broccoli, cantaloupe, carrots, corn, green peppers, kale, mangoes, turnip and collard greens, nectarines, peaches, pink grapefruit, pumpkin, squash, spinach, sweet potato, tangerines, tomatoes and watermelon.

Other antioxidant rich foods include prunes, apples, raisins, plums, red grapes, alfalfa sprouts, onions, eggplant and beans.

It's best to get your antioxidants and other nutrients from food instead of a supplement. There are many different nutrients in food and they work synergistically. Supplements don't have the same mix.

Always be looking for ways to add fruits and vegetables to your diet.

Fruits and vegetables can be fresh, canned (no added sugar or salt), or frozen. Drinking fruit or vegetable juice is an option but be aware that fruit juice is high in calories and vegetable juice may be high in sodium.
