Sugar consumption alone has not been associated with the development of type 2 diabetes. There is of course, weight gain associated with sugar consumption. However, after adjusting for weight gain and other variables, there appears to be a relationship between drinking sugar-laden beverages and the development of type 2 diabetes. Women who drink one or more of these drinks a day have almost twice the risk of developing diabetes than women who drink one a month or less.
A relatively small weight loss of 7 percent of body weight has been shown to help prevent diabetes. Strive to stay at your own lowest sustainable weight, even if that is above what the charts say you should be. It is better to aim for a smaller weight loss and be able to keep that weight off than aim for an unrealistically low number, which could cause a "rebound" effect.
Recently, evidence suggested a link between the intake of soft drinks with obesity and diabetes, resulting from large amounts of high fructose corn syrup used in the manufacturing of soft drinks, which raises blood glucose levels and BMI to the dangerous levels.38 It was also stated by Assy39 that diet soft drinks contain glycated chemicals that markedly augment insulin resistance. Food intake has been strongly linked with obesity, not only related to the volume of food but also in terms of the composition and quality of diet.40 High intake of red meat, sweets and fried foods, contribute to the increased the risk of insulin resistance and T2DM.41 In contrast, an inverse correlation was observed between intake of vegetables and T2DM. Consumption of fruits and vegetables may protect the development of T2DM, as they are rich in nutrients, fiber and antioxidants which are considered as protective barrier against the diseases.42 Recently, in Japanese women, a report revealed that elevated intake of white rice was associated with an increased risk of T2DM.43 This demands an urgent need for changing lifestyle among general population and further increase the awareness of healthy diet patterns in all groups.
