Hmm, informative post on the whole. Anything that encourages people to eat real food is a good thing.
But a couple of things I would take issue with.
Firstly, the lumping together of saturated fats and trans fats as harmful. They are totally different things with different effects on the body. There has never been any proof that saturated fats are harmful. Our ancestors had large amounts of saturated fats with no ill effects, and the sat fat myth has been well and truly debunked. In fact our brains contain a lot of saturated fat and cholesterol. I believe that one of the contributors to the high number of elders with Alzheimers and dementia is chronic deficiency of saturated fat.
Not saying that your omega 3 & 6 are not important. But they are needed in much smaller amounts than sat fats.
Next the GI index. This was a popular diet fad twenty years ago. But now we know that what's a lot more important is the GL - glycemic load. This takes into account everything you eat in the meal, not just the carbs. For eg, if you eat a meal with a pile of "healthy" low GI carbs, if you're not balancing it with protein and fat, it could be a higher GL than a meal with smaller amounts of a higher GI food, that has been balanced with protein & fat.
