A recent study has found an association between trans-fat intake, waist circumference and glycosylated haemoglobin. Waist circumference is a measure of obesity and glycosylated heamoglobin is a diabetes marker.
This study shows that even a small amount of trans fat intake can increase the risk of obesity and diabetes. Trans fats are found in margarine, vegetable shortening, processed cakes, biscuits and deep fried food.
