Here are the Top 5 foods which will help boost your Immune system

 Firstly,  what do you Understand by Immune System?

It might Sound Complicated to Some people's ear' and also might  seems  simple to those who knows exactly what this means. 

Here is the Definition of "Immune System" from 👉  Oxford : the organs and processes of the body that provide resistance to infection and toxins. Organs include the thymus, bone marrow, and lymph nodes.

Definition 2: The bodily system that protects the body from foreign substances, cells, and tissues by producing the immune response and that includes especially the thymus, spleen, lymph nodes, special deposits of lymphoid tissue (as in the gastrointestinal tract and bone marrow), macrophages, lymphocytes including the B cells and T cells, and antibodies   

One of the major roles of the immune system is to guard the body against any foreign matters that might bring about a homeostatic imbalance.

The immune system needs to be able to tell self from non-self. It does this by detecting proteins that are found on the surface of all cells. It learns to ignore its own or self proteins at an early stage.

Scientific studies have shown that whenever an organism in the body is been threatened by microorganisms, viruses, or cancer cells, the immune system acts fast to protect it from any such threat.

Thus, it is safe to claim that without the immune system, our bodies would be open to attack from bacteria, viruses, parasites, and more.

Be that as it may, it is important to note that our immune system must be healthy at all times in other to perform its functions properly.

Here are five numbers of foods that contribute to boosting your immune system

1. Honey

Even before the Canadian Living magazine stated it, a lot of people know that honey has been used as a cold remedy for centuries.

2. Yogurt

Yogurt has been shown to be a great source of vitamin D, and vitamin D does not only regulate the immune system, it also helps boost our body’s natural defenses against disease.

Yogurt starts as fresh milk or cream. It is often first pasteurized, then fermented with various live bacteria cultures, and incubated at a specific temperature to encourage bacteria growth.

• Some yogurts contain active, living bacteria known as probiotics, which can help keep the intestines healthy.

However, when getting a yogurt for the purpose of boosting your immune system, look for the ones that have "live and active cultures" printed on the label, like Greek yogurt; as it will stimulate your immune system to help fight diseases.

Try to get plain yogurts rather than the kinds that are pre-flavored and loaded with sugar.

3. Onions

Research shows that eating onions may help reduce heart disease risk factors, such as high blood pressure, elevated triglyceride levels and inflammation.

Studies have shown that onion is packed with immune-boosting nutrients like selenium, sulfur compounds, zinc, and vitamin C.

In addition, they’re one of the best sources of quercetin, a potent flavonoid, and antioxidant that has antiviral properties as well as histamine regulating effects.

Red onions are rich in anthocyanins, which are powerful plant pigments that may protect against heart disease, certain cancers and diabetes.

Furthermore, onions help to prevent the oxidation of LDL cholesterol, promote relaxation of the vascular smooth muscle, prevent clot formation, and even help to lower blood sugar.

4. Garlic

Garlic is low in calories and rich in vitamin C, vitamin B6 and manganese. It also contains trace amounts of various other nutrients.

Apart from the fact that garlic is rich in Antioxidants( are compounds that inhibit oxidation.) , and has multiple antibacterial and antiviral properties, studies have shown that it has many health benefits, which boost the immune system is one of them.

5. Water (H2O) 

When it comes to boosting the immune system, the importance of water cannot be overemphasized. One of the benefits of drinking water is that adequate hydration has a huge impact on your immune system.

Adequate water intake enables your body to excrete waste through perspiration, urination, and defecation. The kidneys and liver use it to help flush out waste, as do your intestines. 

Water helps all of your body's systems function at optimum levels, as drinking plenty of water flushes toxins and ensures that your cells get all of the oxygen they need to function as they were meant to.
