According to the World Health Organization, diabetes accounts for approximately 171 million people around the world. It is estimated that in the next 20 years, this figure will be doubled. With rapid increase in diabetic cases, concerns for its prevention have always been the first priority of health experts and researchers.[Read: Learn the Risk Factors For Diabetes]


Researchers have been studying the association between vitamin C and diabetes risk. Here is some insight.

Cholesterol lowering abilities of vitamin C have been popular, but vitamin C’s ability to prevent or cure diabetes has only come to light recently. In a study conducted by the scientists of the Institute of Metabolic Science at Addenbrooke's Hospital, Cambridge, England, it was revealed that a diet high in vitamin C can avert the risks of developing type 2 diabetes. The study was published in the Archives of Internal Medicine and is the only study until now to show the impact of dietary vitamin C levels on the risk of onset of type 2 diabetes. The findings of the study were made on the basis of blood samples of almost 22, 000 healthy men and women aged between 40-75 years. After 12 years of follow-up, the blood tests of the participants were taken again and it was found that over the course of the study, 735 people had developed type 2 diabetes accounting for a total of 3.2 per cent of people who took the study.


A comparison of vitamin C levels was made and it was found that those participants, who had higher vitamin C levels, had 62 per cent lesser chances of type 2 diabetes than those who had lower levels of vitamin C or vitamin C deficiency. [Read: Tips to Prevent Type 2 Diabetes]


It was found that those who had significantly higher levels of vitamin C were 77 per cent less likely to develop diabetes than those, who had significantly lower levels of vitamin C.


Apart from vitamin C levels, risk factors of diabetes, such as age, sex, alcohol consumption, tobacco intake, bodyweight, body mass index (BMI) and the patient’s family history of diabetes were also taken into consideration before drawing the conclusion of the study. The link between high dietary vitamin C levels and lower diabetes risk did not show any massive change. [Read: Being Overweight Ups Your Diabetes Risk]


The researchers considered the effect of fruit and vegetable consumption on the risk of onset of diabetes, but suggested that vitamin C levels are a more reliable predictor of diabetes risk.
