Found

Found an interesting site this morning, by accident. It is an explanation of how the digestive system works. (In effect, the regulation mechanisms at work are hellishly complex, but this is a beginning).
It did remind me why I am often ill at ease with all the diet talk: so many carbs, so much protein and so forth. Proteins, fats and starches are the the categories in which the digestive system breaks foods down, and in that order. But are they the best away to think a bout how we should feed ourselves!?

The site also led me to a register of all US clinical trials going on. Awesome.
