Healthy diet, fruit and vegetables and type 2 diabetes
The prevalence of diabetes, predominantly type 2 diabetes goes on increasing worldwide. Type 2 diabetes is a real public health concern as it is associated with higher morbidity and mortality risks than other noncommunicable diseases such as cardiovascular disease. According to numerous studies, changing our dietary habits by adding more fruit and vegetables to our diet may reduce type 2 diabetes risk.
The Global Fruit and Veg Newsletter of this month presents three articles confirming the importance of fruit and vegetables in the management of type 2 diabetes prevention, from diet to specific nutrients.
The first article, based on the British cohort UK Biobank, examines combination of foods when most of studies focuses on associations with nutrients or single foods and the risk of developing type 2 diabetes. The authors show that diets particularly low in fresh fruit and vegetables are associated with a higher risk of developing type 2 diabetes. Indeed, they highlight the importance of taking into account the whole diet and suggest to base dietary guidelines on foods instead of nutrients, as it may also help accelerate behavior change.
The second study aims to explore the dose-response of fruit and vegetables intake and type 2 diabetes risk in almost 40,000 Chinese adults from rural areas of Henan province. This article shows a decrease of the odds of type 2 diabetes with fruit intake higher than 260g/day or fruit and vegetable consumption between 600 and 1000 g/day.
The last article investigates the impact of polyphenols on the glycemic control and metabolic parameters in patients with type 2 diabetes. After an intervention with resveratrol, anthocyanin, and naringin, the authors reported significant reductions in fasting blood glucose, glycated hemoglobin, and low-density lipoprotein cholesterol levels.
Together, these three articles show that adding more fruits and vegetables to our diets is essential in the presentation of type 2 diabetes.
