the researches done over 50 years that I've been following studies into the immune system have evolved from simple blood cells to connections with levels of hydration, diet and gut bacteria.

The immune system reacts similarly to a high fat and high calorie diet as to a bacterial infection. Unhealthy food seems to make the body's defenses more aggressive in the long term. Even long after switching to a healthy diet, inflammation towards innate immune stimulation is more pronounced. These changes may be involved in the development of arteriosclerosis and diabetes.

this increases the risk of a "cytokine storm", an over-excited inflammatory response that causes the clots that can kill or disable a person.

Other people eat healthy food, drink lots of clean water and have a strong gut biome and so have a more effective immune response.
