A study published in the journal Diabetes Care highlights the importance of the whole diet rather than focusing on certain foods or food groups that might be beneficial.

A diet rich in whole grains, fruits and vegetables (leafy green), nuts and low-fat dairy may help people lower their risk of type 2 diabetes by 15% over 5 years than those who ate the lowest amounts of these foods.

In contrast, adults whose diets were high in red meat, high-fat dairy, refined grains like white bread plus beans and tomatoes, saw their diabetes risk go up by 18% as a group.

Type 2 diabetes is closely linked to obesity and it is well–known that maintaining a healthy weight through diet and exercise reduces the risk of developing the disease. Diet affects diabetes risk independent of a person’s weight.
