A strong immune system helps to keep a person healthy. Can specific foods boost the immune system?
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.
Which foods boost the immune system?
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. Popular citrus fruits include grapefruit, oranges, tangerines, lemons, limes and some more. Because your body doesn't produce or store it, you need daily vitamin C for continued 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
Red bell peppers contain twice as much vitamin C as citrus. They’re also a rich source of beta carotene. Besides boosting your immune system, vitamin C may help maintain healthy skin. Beta carotene 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 many other antioxidants and fiber. For these reasons, it is a good choice of vegetables to eat regularly to support immune system health.
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 their value in fighting infections. According to the National Center for Complementary and Integrative Health
Trusted Source, garlic may also help lower blood pressure and slow down the 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
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. However, more research is necessary to confirm whether or not it can effectively prevent illness.
6. Spinach
Spinach may boost the immune system, as it contains many essential nutrients and antioxidants, including flavonoids, carotenoids, vitamin C, vitamin E. Vitamins C, and E can help support the immune system.
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.
