The order of food
Professor Kollath (the same guy who tested on rats) looked into the classification of different types of food according to their biological value. The amount of nutrients and micronutrients is a measure for the biological value of food. Here he made a separation between foods that are alive and foods that are dead and he could make an order. He wrote about it in his book ‘Die ordnung unsere nahrung' (English; the order of our food).
He made a distinction between the different types of food according to their biological value. The more to the right a type of food is, the less micronutrients it has and the less value it has for your health. I see that there are some mistakes in the table underneath (plucked it from the internet), 5, 14, 17 and 23 should be under 'heated', unless you eat eggs raw.
