Type 2 Diabetes - Scientific Pillar

Type 2 Diabetes - Scientific Pillar

The National Institutes of Health suggests that managing blood sugar levels, weight, diet and getting in regular physical activity are the most important treatment goals for people with type 2 diabetes.

A one ounce serving of avocado contains 3 grams of monounsaturated fat and 0.5 of polyunsaturated fat, along with 8% of the recommended daily value of fiber. Both monounsaturated fatty acids (MUFA) and fiber are important nutrients for people with type 2 diabetes. Research suggests that MUFAs may reduce risk factors for developing type 2 diabetesi,ii,iii and may have a positive impact on insulin sensitivityiv,v,vi and high fiber diets (up to 42.5 g/day) may improve glycemic control in people with type 2 diabetes.vii Further, a review study recommends that the diets of people with diabetes provide 12-15% of calories from MUFA and 25-50 g/day of fiber.viii

Future Diabetes Research

HAB is interested in funding research to explore the impact of avocado consumption on risk factors for type 2 diabetes, blood glucose management and insulin response.
