The immune system consists of organs, cells, tissues, and proteins. Together, these carry out bodily processes that fight off pathogens, which are the viruses, bacteria, and foreign bodies that cause infection or disease.
When the immune system comes into contact with a pathogen, it triggers an immune response. The immune system releases antibodies, which attach to antigens on the pathogens and kill them. A healthful, balanced diet plays a vital role in staying well. The following foods may help to boost the immune system.
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. Popular Citrus fruits are Lime, Lemon, Oranges etc.
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 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.
Turmeric is a yellow spice that many people use in cooking. It is also present in some alternative medicines. Consuming turmeric may improve a person’s immune response. This is due to the qualities of curcumin, a compound in turmeric.
Medical reports shows that 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.
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.
People use ginger in a variety of dishes and desserts, as well as in teas. According to a review, ginger has anti-inflammatory and antioxidative properties and is likely to offer health benefits.
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 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.
Almonds are another excellent source of vitamin E. They also contain manganese, magnesium, and fiber. A small handful or a quarter of a cup of almonds is a healthful snack that may benefit the 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 Source of the recommended daily amount.
7. Green tea
Both green and black teas are packed with flavonoids, a type of antioxidant. Where green tea really excels is in its levels of epigallocatechin gallate (EGCG), another powerful antioxidant.
In studies, 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.
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.
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.
10. Dark Chocolate
Dark chocolate contains an antioxidant called theobromine, which may help to boost the immune system by protecting the body’s cells from free radicals. Free radicals are molecules that the body produces when it breaks down food or comes into contact with pollutants. Free radicals can damage the body’s cells and may contribute to disease. Despite its potential benefits, dark chocolate is high in calories and saturated fat, so it is important to eat it in moderation.
