Brief Summary
Nutrients and chemicals in food are able to regulate expression of genetic elements. Gene-nutrient interaction in response to unhealthy diets can increase an individual's 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.

Outcome Measures
Primary Outcomes (1)
tryptophan metabolism
The response of plasma metabolites related to tryptophan metabolism to diets differing in saturated fat and prebiotics content (animal-based diet versus plant-based diet) will vary in individuals carrying CC (n=20) and TT (n=20) genotypes at the common APOA2 -265T\>C single nucleotide polymorphism (SNP)
1 week per intervention arm
Secondary Outcomes (8)
Satiety assessment using plasma levels of leptin
1 week per intervention arm
adipose tissue metabolism
1 week per intervention arm
Plasma Lipoproteins
1 week per intervention arm
Gut microbiota diversity and composition
1 week per intervention arm
Plasma levels of Interleukin 6 to assess inflammatory status
1 week per intervention arm
- +3 more secondary outcomes
