Especially once I began preparing for pregnancy, children's nutrition ~ hand-in-hand with pregnancy nutrition ~ has become one of my key passions. Don't even get me started! ;-) And now you don't have to because some of my associates in the San Francisco Bay Area have re-vamped their very informative site dedicated to children's nutrition. Its focal audience is parents, but I think it does a great ~ thorough yet concise ~ job of speaking to human nutrition in general. And shares resources if you'd like to learn more. Clicking on "For Parents" will take you to the nutritional info.
