My advice to anybody concerned about their health would be to eat something from all four food groups every day, in small portions if you are concerned about your weight, and to take as much fresh air and exercise as your health will allow.
The 'fad' diets, like Atkins, are dangerous and unbalanced
I have decided that I want my food to be as natural as possible, so a little butter instead of a substitute and as many fresh fruit and vegetables as possible. (Although tinned or frozen food can be very nutritious).
I am trying to find full fat yoghurts but there are none in most of the French supermarkets. I think 'fat free' or 'reduced fat' processed food may well contain sweeteners that I don't want..
