If you’ve ever seen those adverts promoting cider vinegar as a weight loss aid, you’ve probably been rather sceptical. After all, how can simply adding vinegar to meals have any beneficial effect? But there appears to be some truth to the old wives tale after all, as two recent studies demonstrate.
The first study on Type 1 diabetics, published in the journal Diabetes Care, found that where two tablespoons of vinegar were added to meals, it lowered the glycemic load by around 20%. This meant that participants experience fewer high blood sugar spikes, which are bad news for anyone and especially diabetics and contribute to weight gain.
The second study published in the European Journal of Clinical Nutrition showed similar affects, and also lowered insulin levels – but only in high-GL meals. Clearly, if you are already eating a low-GL meal – i.e. balanced with slow-releasing carbohydrates and protein – there’s not much vinegar can do to reduce it further. But if you have diabetes, or are overweight or at risk of developing diabetes, then I suggest you follow a low-GL diet rather than take your chances with vinegar alone.
