For our readers in the USA, we've just found a really useful website called "keep it balanced" that you can use to plan your menu, calculate nutrition balance, get fitness tips ... all for FREE. This is a food industry initiative and it looks pretty sensible being based on government recommendations for health.
For Australian, NZ and UK readers, you may have fun playing around on the site, but the product and food composition information (calories) does not apply to countries other than the USA. They do offer a link to a 30 day free trial online fitness training program which looks interesting.
