A theory on nutritional energy consumption

Disclaimer: If you read below you might think I am one of those 'crazy vegans' trying to indoctrinate you. I'm not. I just feel the need to explain more about why everyone should eat more vegetables. I definitely read about this in the book "Eat to Live" a few years ago, and so all my credit here goes to the author Joel Fuhrman.

One part of the "eat sun" idea is that when I eat plant materials I am eating 'purer' energy. Foods that used 'raw' energy from the sun to grow and develop contain the most pure form of nutritional energy possible. This is different from animal and processed products that are less pure being that an animal is a step further away from the sun: the meat I consume was once a live animal that ate plant matter; the plant matter was once an organism that consumed pure sunlight. The raw energy from the sun was once processed by the plant, twice processed by the animal, and is now being processed again in my belly. The same goes for processed foods, where the processing pushes raw, unadulterated plant matter further away from the sun (or in the case of processed meat, you are and even longer way from home). Why not skip the middle man and get some better, cleaner fuel for my body?
