This is an amazing book. It has lasted longer on the shelves than many other books of its kind and packs an influential punch.
The secret of "Diet for a Small Planet" is that it contains something for everyone, whether you believe in vegetarianism, the ecological production of the food supply or just want better health.
If you are an animal activist or don't eat meat for religious reasons, Lappe provides valuable info on how to get the proper balance in your diet by matching foods to get all the essential amino acids you need (the building blocks of proteins.)
If you are interested in health, you can use Lappe's book to provide alternative main dishes that are satisfying and lower in fat, higher in fiber. Meat is a major source of saturated fats, beans and rice and other grains provide lots of benefits such as soluable and insoluable fiber, vitamins and minerals.
If you are ecologically minded, and this is the thrust of the book, you can eat comfortably, knowing your dietary items take up less resources to grow.
I don't subscribe to all Lappe's philosophies, yet, this book had and continues to have a major influence on me. Rice and beans or grains and beans are regular items on our table, meatless days outnumber days when meat is on the table, and this is because I read Lappe's book long ago. I am sure I am better for knowing the information here.
