You Must be Nuts! - Justin smith interview - Part 6

It would naturally lead to high carbohydrate diet because as soon as we start to avoid the foods that contain fat then we would almost automatically start to have more carbohydrates in the diet. And again people have not been given good advice about what constitutes healthy eating. For example, most of us ... well we've all been told that whole grains are healthy and a slow-releasing form of energy. Actually, they're far from that. When you look at the foods which have the worst impact on blood glucose levels, then all of the grain-based foods are the worst foods for doing that. So, because they contain a lot of carbohydrate and that carbohydrate's in grain-based foods like cereals, bread rice and pasta, that carbohydrate is quite rapidly converted into glucose in the bloodstream. We've been given the idea that whole grains, because they're less refined, are a slow-releasing form of energy. Well, it's true that whole grains are slower releasing form of energy than refined grains. So brown bread will have less of an impact than white bread. But because they're all still grains then you don't really benefit much. So it's not that much lower than the white bread would be. And so it's another huge misconception about grain-based foods. And, in fact, to manage our blood glucose levels, what we should be looking at is meals based on meat or fish and vegetables or eggs, with vegetables or pulses or beans and those types of foods, and to minimise the grain-based foods as much as possible.
