It seems reasonable enough - whole grain foods, good amounts of fruit and veg, more accurate guidelines as to what a serving is, etc. However, while I'm glad they awknowledged exercise, the guidelines were somewhat flawed in that area:-

"Exercise at least 30 minutes a day to reduce the risk of chronic disease. Increase it to 60 minutes daily to prevent weight gain and up to 90 minutes daily if you've lost weight and want to keep it off."

60 minutes daily to prevent weight gain? Er, and burn off a couple of stone in the process. For an obese person who is not used to exercises or eating particularly healthily (just using an example - not discriminating), I'd say 30 minutes a day or 60 minutes any other day is ample for very considerable weight loss when coupled with a healthy diet. Launching people onto a program like this was never going to be easy, and proposing guidelines like that isn't going to make it any easier.
