I tried the Eat-Right-4-Your-Type diet and it was very bad. I think that only experimentation can tell what is good for you or not. One theory I have not tried is the Instincto (sic?) from france(?) where you smell food before eating it. If it smells good then eat it. This depends on your sense of smell to tell you what food is good for you right now. The same food may not be good for you tomorrow. When you make a meal you make up lots of raw foods and then snif them before eating. It may be that what your body needs today is just one bite of something, then it does not smell good after the first bite. R. Keene
