Antioxidant-Rich Foods Associated with Lower Risk of Type-2 Diabetes
Type-2 diabetes is caused by a variety of lifestyle factors including obesity, physical activity, diet, and stress. A recent study suggests that consuming more antioxidant-rich foods may reduce the risk of developing type-2 diabetes.
Participants in the study included 64,223 women with a mean age of 52. All of the women completed baseline food questionnaires. Over the course of the 15-year follow-up period, 1,751 of the women developed type-2 diabetes.
The researchers calculated total antioxidant capacity of the women’s diets using the ferric ion-inducing antioxidant power (FRAP) index, excluding coffee. They then separated the women into five groups based on total antioxidant capacity, with the lowest quintile being used as a reference group.
After analyzing the data, the researchers found that a higher antioxidant capacity was significantly associated with a lower risk of type 2 diabetes. Compared with women in the lowest quintile, those in 3rd, 4th, and 5th quintiles had hazard ratios of 0.74, 0.70, and 0.73, respectively. This held true for FRAP values up to 15 mmol per day. After that point, the effect plateaued.
The researchers noted that there was still an association once coffee consumption was factored in, but that the association was weaker. They also noted that it disappeared in people with the highest coffee consumption.
The food groups that contributed the most to the total antioxidant capacity were fruits (23%), vegetables (19%), alcoholic beverages, and hot beverages (12%).
Researchers from University Paris-Sud led the study. It was published online ahead of print on November 9, 2017, in Diabetologia.
The antioxidants found in these foods have been linked with healthier looking skin, heart health benefits and healthier levels of cholesterol. This is often attributed to the ability of antioxidants to fight free radicals in the body.
Adding more of these foods to your diet can be as simple as grabbing an apple as a snack or making sure you have a fruit or vegetable at every meal. Additionally, if you’re looking to boost your antioxidant intake, consider taking a high quality supplement.
