It found:
"Multiple food groups collectively influence type 2 diabetes risk beyond that of the individual food groups themselves."The food group that was associated with a decreased risk for diabetes (15% lower risk) included (not surprisingly) whole grains, vegetables (especially leafy greens), fruit, nuts and seeds, low-fat dairy foods, and coffee.
The food group that was associated with an increased risk for diabetes (18% greater risk) included red meat, processed meat, high-fat dairy foods, refined grains, and soda.
Interestingly, tomatoes and beans were part of the group that increased diabetes risk. The authors speculated that consumption of these foods may reflect a less-than-nutritious diet, since they're often found in highly-processed, high-fat convenience foods such as pizza and tacos.
In this study, no individual food group was associated with diabetes risk.
Participants were 5,011 White, Black, Hispanic, and Chinese-American men and women who took part in the Multi-Ethnic Study of Atherosclerosis (MESA).
