Environment and Nutrition

Beginning at conception, environmental factors in health can accumulate over a lifetime and be from sources as broad as geographic location and economic status to specific external sources including physical activity, occupation, risky behaviors and diet. But some of these factors, especially in terms of diet are highly modifiable.

Important research is now being conducted on this concept of the “exposome,” as an environmental complement to the human genome. NRI researchers are learning how diet and other environmental exposures interact with disease and affect responses to treatment.
