Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The risk of developing cardiovascular diseases increases with aging largely due to age-related declines in the function of arteries (arterial dysfunction), which are influenced by common lifestyle factors such as consumption of a "Western" diet and lack of sufficient physical activity; thus, it is important to study how these factors interact to affect artery function. This study will determine whether changes to the gut microbiome (the collection of bacteria and other "microbes" living in the intestinal tract) with aging, Western diet consumption and aerobic exercise influence arterial function, and the biological pathways (mechanisms) involved. Specifically, the investigators will perform a randomized, single-blind, controlled feeding crossover study design (comparing Western diet to non-Western diet consumption) in young and older, exercising and non-exercising healthy adults to determine the time course effects (temporal association) of diet on the gut microbiome and arterial function. Overall, this research has potential to establish the gut microbiome as a possible target for treating/preventing age-related arterial dysfunction and reducing the risk of age-associated cardiovascular diseases.
