Thanks for the interesting question. Immunity is an important aspect for discussion, especially in the background of Covid 19 (news on second wave of a mutant strain in UK). The easy way out may seem to pop some pills to boost the immunity. But unfortunately, this may only be a short lived action requiring a deeper thought.

Traditionally, our culture has integrated eating appropriate food with good health. For example, our ancestors included variety of cereals such as millets in addition to rice. But the current trend of predominantly rice eating behavior has earned us the label of 'diabetic capital of the world'.

Appropriate food habits is the way forward, endorsed by modern medicine as well. The saying, 'Food is medicine' argues well for the diet as the correct option to gaining immunity.

One of the most important ways you can strengthen your longevity is by boosting your immune system. There is typically a direct correlation between declining immune vitality and declining lifespan. This is common sense since our immune system protects us from infections and helps us respond to various challenges to our healthy homeostasis.

The less efficient your immune system is, the more prone you are to inflammation as well. The good news is that the more you boost your immune system, the better you’re able to cope with the health challenges of daily life regardless of your age

Your first line of defense is to choose a healthy lifestyle. Following general good-health guidelines is the single best step you can take toward naturally keeping your immune system strong and healthy. Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these:

• Don't smoke.
• Eat a diet high in fruits and vegetables.
• Exercise regularly.
• Maintain a healthy weight.
• If you drink alcohol, drink only in moderation.
• Get adequate sleep.
• Take steps to avoid infection, such as washing your hands frequently and cooking meats thoroughly.
• Try to minimize stress.

Several significant factors depend on the immune response. Genetics is an essential factor because it will depend on how we respond to the different external factors that surround us, and this can be seen in how our body in childhood has responded to different antigens (viruses, bacteria, vaccines, allergens, etc.). Another important factor is the diet on which the growth and development of the entire human body depend, both in terms of quantity and quality of the different organs. Medicine is a tool that, from my point of view, allows us to control to a certain extent part of the immune response that in certain cases can be uncontrolled. In these times of pandemic, it is necessary to try to follow a balanced diet in each and every one of the life stages of the human being, so that it can cope with COVID-19, as with other organisms already known with the best state of health.

It is a fact that medicine could improve immunity more but the main weakness is their side effects. diet is known as a reliable method in a long time and is a medicine in a kind. If you want to increase general immunity, a healthy diet, an active and healthy lifestyle is perfect. however, mineral/vitamin supplement could improve the immunity well.

Generally having a healthy lifestyle and diet pattern with a daily intake of mineral/vitamin supplement to provide RDA amount needs is very useful.

If the patients who you want to work on have any medical therapy history, consider the drug, mineral and food interactions. In this case, consult with their medical doctor.
