Even once we get passed the “all sugars are the same” debate and enter the land of common sense, we hit the GI argument. So while I am here, let’s put this to bed too. Yes, “cooked” juice, or pasteurized as it is more commonly known, is indeed high GI. However, what many don’t realize is that although pasteurized apple juice has a high GI (which is every juice you buy in a carton or bottle), freshly extracted apple juice made at home has a low GI. Not that GI is any real indicator of how good or bad a food or drink is anyway. Like many fads, the whole glycemic index trend has more holes than your average colander. (This is true also for subsequent GL [glycemic load] diets.) For example, no two people will react in exactly the same way to a particular carbohydrate. This is why GI tests have to be performed on the same person on different days. Just because an athlete who did the same test got a GI of, say, 60 for a baked potato, doesn’t mean the fat dude on the couch would get the same number. Also, GI tests are done on solo foods and drinks, but rarely do we ever consume one food or drink at a time. If you eat a baked potato on its own you will get a very different reading from when you have some butter or tuna with it. This is why there is no way of actually knowing what the GI level will be for you and your particular combination of foods and drinks. Then of course even if a certain food has a high GI it may have a low GL. Confused? Yes, me too!
