Of course, that view is wrong based on what we know now. That’s what can be most frustrating about science: What’s praised as good today may be condemned as bad tomorrow, and vice versa. It’s not necessarily that we were wrong then and right now. It’s just that our knowledge is constantly growing, and along the way we sometimes have to unlearn what we thought was true.
Here’s a tip that will lower the glycemic index of any meal: Fifteen minutes before you begin eating, have a spoonful of Metamucil in a glass of water. It’s true, this is normally intended as a mild laxative. But it’s simply psyllium, which is fiber—nonsoluble fiber. When you swallow that spoonful, the fiber forms a slippery lump which makes its way through your digestive tract, clearing out anything in its path. When you take some before eating, the fiber gets mixed in with the food and has the effect of slowing the speed with which your stomach digests what you’ve eaten.
Acidic foods such as lemon and vinegar slow the speed with which your stomach empties, therefore cutting back on the rise in blood sugar. You can dress salads or vegetables in both and enjoy the benefit. Even sourdough bread, while not high in fiber, is acidic, and will slow stomach emptying and thereby slow digestion.
Anything that slows the process by which you process the sugars in carbs is by definition, good.
