Some high fat foods have a low GI. Doesn this give a falsely favourable impression of that food?
Yes it does, especially if the fat is saturated fat. The GI value of potato chips or french fries is lowerthan baked potatoes. Large amounts of fat in foods tends to slow the rate of stomach emptying and therefore the rate at which foods are digested. Yet the saturated fat in these foods will contribute to a much increased risk of heart disease. It is important to look at the type of fat in foods rather than avoid it completely. Good fats are found in foods such as avocadoes, nuts and legumes while saturated fats are found in dairy products, cakes and biscuits. We’d all be better off if we left the cakes and biscuits for special occasions.
