The immune system... Can we modify it?
The immune system does a tremendous job of defending the human body from disease-causing microorganisms. But every once in a while it fails: a germ invades correctly and makes you sick. The good news is that we can intervene in the process and improve our immune system.
What to eat?
1. Citrus fruits
Most people turn straight to vitamin C after they’ve caught a cold. That’s because it helps build up your immune system. Vitamin C is thought to increase the production of white blood cells, which are key to fighting infections. Almost all citrus fruits are high in vitamin C. With such a variety to choose from, it’s easy to add a squeeze of this vitamin to any meal. Because your body doesn’t produce or store it, you need daily vitamin C for continued health.

2. Red bell peppers
Red bell peppers contain almost 3 times as much vitamin C as a Florida orange. They’re also a rich source of beta carotene. Besides boosting your immune system, vitamin C may help you maintain healthy skin. Beta carotene, which your body converts into vitamin A, helps keep your eyes and skin healthy.
3. Broccoli
Broccoli is supercharged with vitamins and minerals. Packed with vitamins A, C, and E, as well as fiber and many other antioxidants, broccoli is one of the healthiest vegetables you can put on your plate. The key to keeping its power intact is to cook it as little as possible or better yet, not at all.

4. Garlic
Garlic is found in almost every cuisine in the world. It adds a little zing to food and it’s a must-have for your health. Garlic may also slow down hardening of the arteries, and there’s weak evidence that it helps lower blood pressure. Garlic’s immune-boosting properties seem to come from a heavy concentration of sulfur-containing compounds, such as allicin.

5. Ginger
Ginger is another ingredient many turn to after getting sick. Ginger may help decrease inflammation, which can help reduce a sore throat and inflammatory illnesses. Ginger may help with nausea as well.
Ginger may also decrease chronic pain and might even possess cholesterol-lowering properties.

6. Spinach
Spinach is rich in vitamin C and it’s also packed with numerous antioxidants and beta carotene, which may both increase the infection-fighting ability of our immune systems. Similar to broccoli, spinach is healthiest when it’s cooked as little as possible so that it retains its nutrients. However, light cooking makes it easier to absorb the vitamin A and allows other nutrients to be released from oxalic acid, an antinutrient.

7. Yogurt
Try to get plain yogurts rather than the kind that are flavored and loaded with sugar. You can sweeten plain yogurt yourself with healthy fruits and a drizzle of honey instead.
Yogurt can also be a great source of vitamin D, so try to select brands fortified with this vitamin. Vitamin D helps regulate the immune system and is thought to boost our body’s natural defenses against diseases.

8. Almonds
When it comes to preventing and fighting off colds, vitamin E tends to take a backseat to vitamin C. However, this powerful antioxidant is key to a healthy immune system.
Adults only need about 15 mg of vitamin E each day. A half-cup serving of almonds, which is about 46 whole, shelled almonds, provides around 100 percent of the recommended daily amount.

9. Sunflower seeds
Sunflower seeds are full of nutrients, including phosphorous, magnesium, and vitamins B-6 and E. Vitamin E is important in regulating and maintaining immune system function. Other foods with high amounts of vitamin E include avocados and dark leafy greens.
Sunflower seeds are also incredibly high in selenium. Just 1 ounce contains nearly the selenium that the average adult needs daily. A variety of studies, mostly performed on animals, have looked at its potential to combat viral infections such as swine flu.

10. Turmeric
Has been used for years as an anti-inflammatory in treating both osteoarthritis and rheumatoid arthritis. The high concentrations of curcumin, which gives turmeric its distinctive color, can help decrease exercise-induced muscle damage. Curcumin has promise as an immune booster and an antiviral.

11. Green tea
12. Papaya
Papaya is another fruit loaded with vitamin C. Papayas also have a digestive enzyme called papain that has anti-inflammatory effects. Papayas have decent amounts of potassium, magnesium, and folate, all of which are beneficial to your overall health.

13. Kiwi
Like papayas, kiwis are naturally full of a ton of essential nutrients, including folate, potassium, vitamin K, and vitamin C. Vitamin C boosts the white blood cells to fight infection, while kiwi’s other nutrients keep the rest of your body functioning properly.

14. Poultry
Poultry,
such as chicken and turkey, is high in vitamin B-6. About 3 ounces of light
turkey or chicken meat contains nearly one-third of your daily recommended
amount of B-6.
Vitamin B-6 is an important player in many of the chemical reactions that happen in the body. It’s also vital to the formation of new and healthy red blood cells. Stock or broth made by boiling chicken bones contains gelatin, chondroitin, and other nutrients helpful for gut healing and immunity.
15. Shellfish
Shellfish isn’t what jumps to mind for many who are trying to boost their immune system, but some types of shellfish are packed with zinc.
