I am suspect of diets which try to eliminate nutritional sources. Many nutritional elements may be necessary but not needed with every bite you take. It may take a long time before any long term health effects are seen. Scurvy, kwashiorkor, hypothyroidism, anemia, and other effects from nutritional deficiencies don't show up immediately. Effects of overabundance take a long time as well. Obesity, kidney stones, liver disease, arteriosclerosis, and much more may take decades to present themselves. Many combinations have to be present at the same time for complete nutrition.
We really don't know what is the absolute optimal nutrition. We evolved in a different environment from the one we live in today. The change started with the advent of agriculture. We suddenly had a surplus of calories that can mask many natural cravings brought about by deficiencies. You can survive a really long time on a bad diet.
This is not even considering the fact that we are not simple organisms. We carry a menagerie of flora and fauna along with us in our digestive system. They outnumber the cells in our body.
You have a much better chance of getting the full array of necessary nutrients with a more diverse diet.
