The media is always claiming that certain ingredients can help us to maintain a healthy lifestyle and improve our wellbeing. The latest headlines state that yoghurt is key to beating diabetes; a claim based on a study which associates dairy with the risk of developing type 2 diabetes. The study found that the risk of diabetes was significantly lowered by as much as 28 per cent in people who ate large amounts of low-fat yoghurt, compared to people who ate none at all. The results were similar in people who ate more of all low-fat fermented products, including cottage cheese and fromage frais. The study was based on people using food diaries to report their dairy intake around the time of eating, which is one of the best ways to gauge the success of a trial rather than asking people to recall what they’ve eaten throughout the day – it tends to be more accurate. The diaries were only used over a seven-day period (which isn’t a long enough to provide an accurate assessment of whether yoghurt can help with diabetes risks). It’s not currently clear whether fermented low-fat dairy products can help to prevent diabetes, but it is a theory researchers are keen to investigate. There are a number of steps you can take to lower your risk of developing diabetes though, such as regular exercise, eating a balanced healthy diet, quitting smoking and lowering your alcohol intake. It’s also important to note the sugar levels in the foods you eat, as these can contribute towards developing not just diabetes but also obesity. If you’re concerned about your diet or weight, it’s important to seek advice as this can contribute to a number of health concerns, in addition to diabetes, such as heart problems and certain cancers.
The study was carried out by the University of Cambridge, as part of a larger study funded by the Medical Research Council and Cancer Research UK. Researchers discovered that people who ate the most low-fat fermented products were 24 per cent less likely to develop type 2 diabetes than those who ate the least. The total dairy, high fat dairy, milk and cheese were not associated to the development of diabetes, nor was low-fat dairy. There are several limitations to this study which have led researchers to question whether or not yoghurt can actually help lower the risk of diabetes. Firstly, people’s reported dairy intake was only collected once, at baseline, over a seven-day period, so it’s possible that people’s diets didn’t stay the same during the 11 year follow-up period. Furthermore, the information was self-reported which could affect the reliability. Lastly, researchers didn’t take into account the dairy products included in cooking composite dishes. While there were attempts to take account of other factors, it is always possible that measured and unmeasured factors had an influence on the results. Further studies need to take place in order to know for certain whether fermented products can help to lower the risk of diabetes. The results do suggest that switching sugary snacks and meals for low-fat dairy products could help your overall health, as well as improving your diabetes prospects. Just be sure to choose low sugar varieties and to balance your diet with plenty of fruit and vegetables, grains and lean protein to ensure your body is getting all the nutrients it needs to stay healthy.
