Can what I eat affect my DNA?

Is it possible to eat better to improve my genes

Sort of. I found an explanation for this on a website. “new studies have recently found that nutrients in foods and drinks can also affect how our DNA and genes behave. In fact, nearly 9 out of 10 genes in our body are adjusted by the available nutrients. This also explains why people often respond differently to some drugs. […] Researchers have found out that nutrients in foods can change how proteins are generated in nearly all genes in our body. And this, of course, will have a direct influence on our health. Proteins are basically the workers in the cells and our body uses them in a variety of biological activities. For instance, some components work as the ‘building blocks’ for nails and hair, while muscles consist of proteins called myosin and actin.”
