Increased consumption and variety of fruit and vegetables and the impact of type 2 diabetes

Diabetes is becoming more common in the world. Type 2 diabetes is the most common form of diabetes, which occurs in 90% of cases of diabetes. Usually occurs after the age of forty, and one of the main reasons for his big appearance is that more and more people eat unhealthy food and take over Western eating habits. Patients with type 2 diabetes still produce normal amounts of insulin, but become resistant to its action due to a disturbance in the liver and muscle. With Type 2 diabetes is related the development of obesity, but also concerned the increasing occurrence of type 2 diabetes in children, which occurs due to the growing number of obese children.

Scientists have conducted scientific studies about the connection between the consumption of fruits and vegetables and the incidence of diabetes type 2. The objective of the study was to determine how the quantity and variety of fruit and vegetables affects the occurrence of type 2 diabetes. World Health Organization (WHO) today recommended the consumption of at least 400 g fruits and vegetables in five portions per day , for the prevention of noncommunicable diseases. For the study uses data from older studies EPIC-Norfolk, which has studied the connection of diet and cancer. Using the data on the observed person for the purposes of the EPIC-Norfolk study. From the cohort of 25,639 people from the EPIC-Norfolk study, at the end is observed 3,166 people. Observed people have made a seven-day food diary, which is being confirmed by weighing the food, urine and blood biomarkers. Also, completing an extensive questionnaire on lifestyles and habits (such as education, social status, smoking status), health status questionnaire, collected data on weight, waist circumference, and BMI. Observing is average lasted 10.9 years. Less than 26% of the observed person had consumed at least 5 portions a day.

The results showed that a greater variety of fruit and vegetables have a positive effect on the prevention of type 2 diabetes. Eating larger amounts of vegetables also have a positive effect on the prevention of type 2 diabetes, while increasing consumption of fruits showed no connection with the prevention of type 2 diabetes. It was calculated that increased intake of fruit and vegetables for the two new species weekly, reduces the occurrence of type 2 diabetes for 8%. Scientists point out that these results provide support for efforts that in the daily diet included more fruits and vegetables, because the healthier diet has proven to have positive effects in the prevention of several diseases, including type 2 diabetes.
