Top 15 Foods To Boost Your Immunity: How To Boost Natural Immunity/
Food for immunity boost
1. Citrus fruits
Most people turn 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. These are key to fighting infections.
And most Popular citrus fruits like:
grapefruit
oranges
lemons
as your body doesn't produce or store it, you need daily vitamin C for your health. 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.
2. Red bell peppers
If you think citrus fruits have the most vitamin C of any fruit or vegetable, think again. red bell peppers contain twice as much vitamin C as citrus. They’re also a rich source of beta carotene. Beta carotene helps keep your eyes and skin healthy. Beta-carotene is a powerful antioxidant that can reduce inflammation and boost immune function by increasing disease-fighting cells in the body. Excellent sources include sweet potatoes, carrots, and green leafy vegetables.
3. Broccoli
Broccoli is supercharged with vitamins and minerals. Packed with vitamins A, C, and E, as well as many other antioxidants and fiber, broccoli is one of the healthiest vegetables you can put on your table. 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. Early civilizations recognized its value in fighting infections. garlic may also help lower blood pressure and slow down hardening of the arteries. 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 other inflammatory illnesses. Ginger may also help decrease nausea.
While it's used in many sweet desserts, ginger packs some heat in the form of gingerol, a relative of capsaicin. Ginger may help decrease chronic pain and may possess cholesterol-lowering properties.
6. Spinach
Spinach made our list not just because it's rich in vitamin C. It's also packed with numerous antioxidants and beta carotene, which may 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 enhances its vitamin A and allows other nutrients to be released from oxalic acid.
7. Yogurt
Look for yogurts that have "live and active cultures" printed on the label, like Greek yogurt. These cultures may stimulate your immune system to help fight diseases. Try to get plain yogurts rather than the kinds that are preflavored 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 vitamin D. 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, vitamin E is key to a healthy immune system. It’s a fat-soluble vitamin, meaning it requires the presence of fat to be absorbed properly. Nuts, such as almonds, are packed with the vitamin and also have healthy fats. A half-cup serving, which is about 46 whole, shelled almonds, provides nearly 100 percent of the recommended daily amount of vitamin E.
9. Turmeric
You may know turmeric as a key ingredient in many curries. But this bright yellow, bitter spice has also been used for years as an anti-inflammatory in treating both osteoarthritis and rheumatoid arthritis. It has high concentrations of curcumin , which gives turmeric its distinctive color, and can help decrease exercise-induced muscle damage.
10. Green tea
Both green and black teas are packed with flavonoids, a type of antioxidant. green tea really excels in its levels of epigallocatechin gallate, or EGCG which is another powerful antioxidant. EGCG has been shown to enhance immune function. The fermentation process black tea goes through destroys a lot of the EGCG. Green tea, on the other hand, is steamed and not fermented, so the EGCG is preserved.
Green tea is also a good source of the amino acid L-theanine. L-theanine may aid in the production of germ-fighting compounds in your T-cells.
