 Nutrients and chemicals in food are able to regulate expression of genetic elements. Gene-nutrient interaction in response to unhealthy diets can increase an individuals risk, shifting the individual from health toward the development of chronic disease. The apolipoprotein A2 APOA2 gene may either put individuals at risk for or protect from obesity in the presence of certain fats in food. The main purpose of this four-week study is to examine diet induced gene-nutrient interaction, with a focus on gut health, gut microbiota and inflammation in individuals who have either the CC or the TT form within a specific variant of the APOA2 Gene. The 2 one-week study diets, one plant based and the other animal based are separated by a 1 week return to your regular habitual without probiotic or prebiotic food products.
