3 Tips for Boosting Immune Support:

Tweet You already know you need to eat well to stay healthy, but scientists are now zeroing in on specific diet strategies that can help boost your immunity. With cold and flu season right around the corner, here are three to add to your arsenal.

1. Fill Your Vitamin D Tank:

You may have fewer health problems—ranging from colds to cancer,if you get enough vitamin D. Your body naturally makes vitamin D from sunlight. You can also get it in smaller doses from fatty fish, such as: salmon, and from fortified milk. Most Americans don’t get enough vitamin D, most experts recommend a D supplement. New research in the American Journal of Clinical Nutrition suggests that taking such a supplement may help boost your immune system. In a study of more than 300 Japanese children, those who took daily vitamin D supplements (1,200 IU) were 40 percent less likely to get a common flu virus than kids who took a placebo. Laboratory studies indicate that the nutrient may help immune cells identify and destroy bacteria and viruses that make us sick. Aim to get at least 1,000 IU of vitamin D daily (check with your doctor before taking more).

2. Get A Daily Dose Of Soluble Fiber:

Mice that ate a diet rich in soluble fiber for six weeks recovered from a bacterial infection in half the time it took mice that chowed on meals containing mixed fiber, according to a recent study. Soluble fiber in abundance is found in citrus fruits, apples, carrots, beans and oats. Soluble Fiber also help fight inflammation. Insoluble fiber which is found in wheat, whole grains, nuts and green leafy vegetables is still important for overall health, but it doesn’t seem to have the same impact on immunity. Strive for 25 to 38 grams of total fiber a day, paying extra attention to getting the soluble kind.

3. Stay Lean:

Overweight adults who cut their daily calorie intake by nearly a third saw a 50 percent boost in immunity, according to a six-month study out of Tufts University. (Those who cut calories by 10 percent had smaller improvements.) Restricting calories may reduce levels of compounds in the body that depress your immune response. Animal studies suggest that calorie restriction could work in normal-weight individuals too. Try to maintain your body weight at what is considered ideal, because eating more than what you need drags the immune system down. And remember: when you cut back on quantity, you need to be even more vigilant about the quality of your diet. Try to eat more fruits and vegetables. Choose lean protein sources, such as fish, chicken and low-fat dairy.
