Eating more yoghurt can reduce the risk of type 2 diabetes

The study, published in the journal Diabetologia, shows that eating yoghurt in place of other snacks, such as crisps, can reduce the risk of developing type-2 diabetes. The study also found that higher consumption, compared to no consumption,  of yoghurt, can reduce the risk of new-onset type-2 diabetes by 28%, and that higher consumption of low-fat fermented dairy products – including all yoghurt varieties and some low-fat cheeses – also reduced the relative risk of diabetes by 24% overall.

Lead researcher, Dr Nita Forouhi, from the Medical Research Council Epidemiology Unit at the University of Cambridge says: “This research highlights that specific foods may have an important role in the prevention of type-2 diabetes and are relevant for public health messages.”

A review of the research by the  University of Cambridge, reveals that the research was based on the large EPIC-Norfolk study, which includes more than 25 000 men and women living in Norfolk, UK. It compared a detailed daily record of all the food and drink consumed over a week among 753 people who developed new-onset type-2 diabetes, followed by  11 years of follow-ups with 3 502 randomly selected study participants. This allowed the researchers to examine the risk of diabetes in relation to the consumption of total dairy products as well as individual dairy products. Total dairy, total high-fat dairy or total low-fat dairy consumption was not associated with new-onset diabetes, once important factors like healthier lifestyles, education, obesity levels, other eating habits and total calorie intake were taken into account. Total milk and cheese intakes were also not associated with diabetes risk. However, those with the highest consumption of low-fat fermented dairy products (such as yoghurt, fromage frais and low-fat cottage cheese) were 24% less likely to develop type-2 diabetes over the 11-year period, compared with non-consumers. Previous studies on the link between dairy product consumption (high fat or low fat) and diabetes have proved inconclusive, prompting this more detailed assessment of diary product consumption. While this type of study cannot prove that eating dairy products caused the reduced diabetes risk, dairy products do contain beneficial constituents such as vitamin D, calcium and magnesium. In addition, fermented dairy products may exert beneficial effects against diabetes through probiotic bacteria and a special form of vitamin K (part of the menaquinone family) associated with fermentation.

“At a time when we have a lot of other evidence that consuming high amounts of certain foods, such as added sugars and sugary drinks, is bad for our health, it is very reassuring to have messages about other foods like yoghurt and low-fat fermented dairy products, that could be good for our health,” said Dr Forouhi.

Type-2 diabetes is common and its incidence is increasing. In 2013, there were 382 million people worldwide with diabetes and by 2035 that number will increase to 592 million, according to the International Diabetes Federation.
