“As genetic science moves forward with lightning-fast speed, researchers have begun to understand that while certain individuals have genetic predispositions to developing certain diseases, the diseases may not actually occur.
Why do some genetically-predisposed people get sick, while others do not?
In many cases, some component of diet triggers, enhances, or suppresses certain gene interactions.
Some dietary factors lead to increased protection from disease in susceptible individuals, while other dietary factors lead to increased risk of disease.
Nutrigenomics concentrates on the impact of diet and lifestyle factors, such as food, nutrition, stress, and toxins on gene expression.” — Dietitians in Integrative and Functional Medicine
