Have you ever realized what keeps you from falling prey to cough and sneezing when you expose to dust? A parade of vehicles moves past you scattering dust around in the air that you inhale and yet you do not fall sick. You do not feel irritation at your throat, you do not feel like squeezing your nose to get rid of itching, and your eyes do not get watery. Here comes the role of immunity.

The immune system is a kind of shield you need to protect yourself from the attack of viruses, bacteria, allergens and other similar threats. Unfortunately, sometimes it fails to perform at its full potential and leave you exposed to various diseases. Immunity plays a crucial role to keep you healthy and fit. However, not everyone is blessed with stronger immunity.

If you have low immunity, you are highly likely to be exposed to infections. Food plays a paramount role to boost your immunity, but some people are prone to various infections despite taking a healthy diet. Why does it happen? Genes! Genes are highly responsible for the decision if you will have stronger immunity or lower immunity. Items that will be on your menu will be based on your taste and preferences, but experts suggest that you should add food items in your menu after looking over your family tree.

Genes determine your eyes color, hair texture, body shape, and height; the same way they can also decide which food items are best for you.

The connection of genes with diet

The sign of stronger immunity is good gut health. When your gut is healthy, you feel fit and healthy. Since small intestines absorb nutrients from the food you eat, they must have enough microbes to function effectively. Your gut consists of a mix of both good bacteria and harmful bacteria.

There must be a balance between both of them. According to experts, you should have good bacteria more than bad bacteria to make your gut function properly. As long as it can absorb all nutrients from what you eat, you will have good immunity. However, health issues are likely to rise immediately if you are taking an unhealthy diet or taking a lot of stress.

It depends on your genes, whether a particular food item will agree with your stomach or not. Some researchers have found that cultures have eaten specific diets for generations and therefore their guts are adapted to that particular diet, which is why Asians tend to eat plant-based food while Africans tend to eat more meat.

You must have seen that some people have lactose intolerance. While one can easily digest oily food, the other from the same family cannot. There is only one answer to all these scenarios – genes. However, not every time, genes are responsible for something. Sometimes, your body tends to behave like it. Now you must have understood that there is no one-diet-fits-all in that you all belong to people from different cultures and ethnicities.

Find food that is best for your gut.

If you want to improve immunity, you need to eat food that agrees with your gut. Finding the best food for your gut is not that easy because you all are from different backgrounds, cultures and ethnicities. Some experts suggest that you should try out testing kits like 23andMe (to get a report about microbes) and Viome (to identify which food will keep your gut thriving and which will make you sick).

However, both testing kits will set you back some money. There is nothing to worry about if you can afford them. Otherwise, you can take out B.I.G loans. Your role is not over just because you have identified which food will agree with microorganisms in your gut. You need to remember if you suffer from a side effect after incorporating a new diet.

If it makes you feel bloated and sapped, you should stop continuing because it does not agree with your stomach. If you do not find any side effects, it does not mean you have to be restricted with this diet. You can try other food items too. A good rule of thumb says that you should prefer a healthy diet.

Eat everything from greens to meat and then identify how you feel after consuming a particular type of food. Best food items for boosting immunity are olive oil, nuts, and cold fish like salmon. However, it is not just that food has the only role in improving your immunity. It would help if you also improve your lifestyle.

Your lifestyle can change your genes.

Having said that it is not only your genes that determine your health condition, it also depends on your body how it feels like after eating or drinking something. You cannot be entirely at the mercy of genes because your lifestyle choice can also affect your health.

While family history is a strong predictor of diseases that you can catch at a later stage in life, your healthy lifestyle choices can put that risk-off. For instance, fruits and vegetables can lower down the risk of diabetes because they do not consist of processed sugar and slow down digestion because of fiber. Further, it would help if you avoided smoking and alcohol to keep your liver and respiratory system healthy.

Well, as far as it is about boosting your immunity, you need to take care of your diet. You cannot change your genes, but you can change your lifestyle.
