That's really the key to what is fixing the diabetes. And it's just a brief mention in the article. Nothing else about the nutritional aspects. This was extremely light on actual, real information.
That being said, I'm also not sure why this stuff is still considered news. Many people, myself included, have been saying for some years now that low-carb is the way to go. I'm glad this stuff is getting press, but I'm just surprised that people seem to be acting like this hasn't already been known for quite a while.
The real problem is that people can easily fix this themselves, but they either 1) don't know this information or 2) don't have the willpower. It's more of #2 though, because people generally know when they are eating garbage. There might be some foods that surprise people as having extremely high glycemic responses, but most of the time they know what they should be avoiding. The problem, I think, is that they don't quite know exactly how horrible what they are consuming really is for their metabolic processes. The one that seems to surprise people is potatoes. They know french fries are bad, but think it's because they are deep fried. When I tell them that a regular baked potato or red potatoes have glycemic index values of around 85-89 and that potato chips are around 50-55 they are stunned. I don't know why, but they are. If you are consuming the same mass of food for comparative purposes, the potato chips are loaded with fats where the regular potatoes are not so that makes sense to me that it would be lower. This tells me there is a serious lack of education on this topic and it is quite literally costing people their lives.
