How does the human body improve its own immunity

Each of us has our own immunity. If the immunity is stronger, the chance of getting sick will be greatly reduced. Even if germs and bacteria invade the body, they can all be eliminated if the immunity is strong. If your immunity is poor, you may feel sick, often catch colds and fevers, and be easily infected with other diseases. So, how to improve human immunity?

1. Elderberry

Fighting colds with elderberry extract is an old folk remedy that's been backed up by recent scientific research. Results of a small human study suggest that elderberry may help improve recovery from the common cold. But the scientists warned that further research is needed. Elderberries are rich in antioxidants and also have anti-infection properties.

2. White mushrooms

Don’t assume that mushrooms have no nutritional value just because they don’t grow tall. Mushrooms contain the mineral selenium and antioxidants. Low levels of selenium in the body often increase the risk of worsening a severe cold. Mushrooms also contain the B vitamins riboflavin and niacin, which play an important role in maintaining a healthy immune system.

Animal experiments also show that white mushrooms have antiviral, antibacterial and anti-tumor effects.

3. Acai Berry

Although grown like a blueberry but marketed as a superfood, the acai berry's dark color is a reflection of its high content of the antioxidant anthocyanin. Although acai berries have not been linked to or have any disease-fighting properties, the antioxidants in them may help fight aging and disease. Acai berries can be juiced, mixed with milk, or dried and added to oatmeal.

4. Oysters

Because oysters contain the mineral zinc. Male infertility is associated with low zinc levels in the body. Zinc can also fight viruses, but scholars cannot explain why. However, zinc has been implicated in several functions of the immune system, including wound healing.

5. Watermelon

Ripe watermelon also contains high levels of the powerful antioxidant glutathione, which has hydrating and refreshing effects. Since it helps strengthen the immune system, it can fight infection. Glutathione is located in the red soil near the melon rind.

6. Cabbage

Cabbage is another plant rich in glutathione, which has immune-boosting properties. Cabbage is also readily available and inexpensive during the winter months when in season. Adding a variety of cabbage (white, purple, Chinese) to soup and simmering it slowly allows antioxidants to be released into the soup, increasing the nutritional value of the food.

7. Almonds

A handful of almonds can boost your immune system's ability to fight stress. The recommended 1/4 cup serving of almonds contains almost half the daily requirement of vitamin E, which can boost immunity. Almonds contain riboflavin and niacin, B vitamins that also help fight stress.

In fact, to improve your immunity, it is recommended to communicate more with friends and maintain a certain level of friendship. If people have more contact with the outside world, they will definitely be less likely to get sick. The reason is that if they frequently interact with the outside world, the brain will not produce substances that cause anxiety, so people's life span and ability to resist disease will be greatly improved.
