Investigating a Mediterranean Dietary Pattern With White Potatoes on Cardiometabolic Health in Adults With Pre-diabetes From Diverse Racial and Ethnic Backgrounds

In the United States, one in three adults has pre-diabetes, and 80% are unaware that they are at risk of developing type-2 diabetes (T2D). Elevated blood glucose levels are associated with an increased risk of heart disease, obesity, dyslipidemia, and hypertension. African-American and Hispanic individuals are disproportionately affected by pre-diabetes and its complications, such as arterial stiffness and obesity, compared to Caucasians. Approximately 70% of those with pre-diabetes may develop T2D, therefore it is crucial to find effective ways to manage and reverse these conditions. Potatoes, which contain a good source of resistant starch, potassium, and other beneficial nutrients, might help improve blood glucose control and heart health. Studies have shown that potatoes, especially with their skin, can improve insulin sensitivity, satiety, and cholesterol levels. However, minority groups in the U.S. tend to eat fewer potatoes compared to Caucasians. Combining potatoes with nutrition education focusing on the Mediterranean diet, could be a practical approach to improving blood glucose levels, heart health, and overall diet quality in people with pre-diabetes. This study aims to explore the effects of incorporating baked potatoes with skin, alongside nutrition education focusing on the Mediterranean Dietary Pattern, in diverse racial and ethnic groups with pre-diabetes.
