Are proteins always made inside cells? One of the building blocks to the construction of proteins are amino acids. When we eat food, especially protein, our digestion attempts to break the protein down into smaller parts.
But some foreign protein are not digested, are not broken down, and they get into the bloodstream. Now, I hope foreign proteins are too big to squeeze through the cell channels, the walls, the membrane. My concern is that I don't want too much of the wrong stuff getting into the cells. Now, it seems that too many germs, proteins, etc, can get into our bloodstream. The immune system fights back like you said. But the more you got in the blood, the more the body has to work to flush it out. That is why people should fast sometimes. People should experiment on diets. People need to rest sometimes. People need to slow down and stop eating certain things or altogether. Sadly, people may not give their bodies enough time to recover, to bounce back. Germs can probably eat some of what is supposed to go to our cells. That means our cells begin to decay, to fall apart, to grow poor, hungry, old, weak. That might be like an indirect effect that germs, viruses, etc, can have on our cells, etc.
Eating foods, herbs, vitamins, etc, that can help strengthen the walls of the cells is probably one of the secrets to health. The only thing more vital to that might be to do whatever you have to do to boost up your immune system. Would you agree? Like you said, the body tries to take care of itself. It auto corrects as much as it can. So, of course, we have to always try to consume specific minerals, vitamins, enzymes, water, air, sunlight, Vitamin C, calcium, magnesium, iodine, sodium, etc. Without enough of some of these things, we can begin to decay, to die.
I'm watching this video and it is talking about some of these things.
