u do understand that the food that u eat infact DOES change ur DNA stucture dont u?
You may not expect this answer, but indeed it may happen. Here's how:
1. By eating radioactive material or chemical carcinogens. Indeed ionizing radiations and chemical carcinogens do in fact modify the DNA very very little, in very very very few cells, but in sometimes dramatic ways. Cancer is an example starting from one bad cell.
2. Substances called antigens. We eat those all the time; our immune system create antibodies to fight them; end of story. My point is that in natural process of creating antibodies, very rare white blood cells (B-cells) change a tiny bit of their DNA to make the right antigen.
So technically you are correct, sometimes food do induce a change to our DNA content. But let me say this: The above two examples I mentioned refer to
individual cells and that, in rare occasions.
The DNA in my hands will be the same from birth to death. I mean rigorously the exact same.
