How is Nutritional Genomics being used to improve health? Group of answer choices The food we eat contains thousands of biologically active substances, many of which may have the potential to provide substantial health benefits (for example: by decreasing our risk of cancer by either up-regulating or down-regulating the expression of certain genes). Indeed, several food derived compounds—such as sulphoraphane, curcumin, lycopene, and tea polyphenols—are among the most promising chemopreventive agents being evaluated. Nutrigenomics helps us understand how genes determine the effects nutrients on the body and health. Nutritional Genomics improves our health by positively altering our genes within our DNA. When we consume a healthy diet for example, the genetic material within our DNA is altered to decrease our risk for diseases such as cancer.
