Research studies have shown that plant-based diets confer cardiovascular and metabolic health benefits. Asian Indians (AIs) in the US (who have often followed plant-based diets) have elevated risk for chronic diseases such as diabetes, metabolic syndrome, and obesity suggesting ethnic vulnerability that imply genetic and/or lifestyle causative links. This study explored the association between this ethnic group and diabetes, obesity, and metabolic syndrome after controlling for demographics, acculturation, family history of diabetes, and lifestyle and clinical risk factors.

OBJECTIVES:
A vegetarian diet may prevent elevation of blood pressures and lower the risk for hypertension through lower degrees of obesity, inflammation, and insulin resistance. This study investigated the association between a vegetarian diet and hypertension incidence in a cohort of Taiwanese adult nonsmokers and examined whether this association was mediated through inflammation, abdominal obesity, or insulin resistance (using fasting glucose as a proxy).

Several previous cross-sectional studies have shown that vegetarians have a better metabolic profile than non-vegetarians, suggesting that a vegetarian dietary pattern may help prevent chronic degenerative diseases. However, longitudinal studies on the impact of vegetarian diets on metabolic traits are scarce.
