In 1900 Quantum Mechanics appeared. It marks the highest level attained up to now, in the brain evolution. However, people, who reached this extreme advance of knowledge, are ordinary people in everyday life. Independent of the level in the professional field, in everyday life, the brain continues to act to a large extends based on image models. I have an example, in which one can see clearly, and above any doubt, the evolution of the brain towards more and more advanced symbolic models, at the level of the common person, in an issue always associated with image models: nutrition. In all times, people have eaten based on analysis on image models. Associated terms to nutrition are taste, smell, colour, aspect etc. The decision to eat or not a certain food, is based on image models. It can be said that the whole being, with its whole structure, participates at solving the nutrition problem. We have an explicit situation, when the process of evolution towards symbolic models in nutrition is clear. I have seen a person in a shop, who wanted to buy a certain product. The person had at hand a list of dangerous food additives (the so-called "E"s). A product was rejected because it contained such an "E". Taste, smell, aspect and natural drive were overrun and a logical decision taken, totally independent of any image model. "E"s cannot be sensed based on image models. When a decision is taken exclusively on symbolic models, we have clearly a progress. This phenomenon, according to MDT, will increase on all levels. Important note: the elite has imposed that any food should be labeled with the exact contents and other data, so that evolved people can take their own decision. This type of information is useless for the image-type public. The real problem is not the information, but the technical capacity of the brain to collect information and decide based on symbolic models. As I mentioned, the attitude of the majority of consumers continues to be strongly anchored in a complex structure of image models. There is an infinite number of cases, in which the image models from one's mind, make the products more expensive, and also more dangerous. Example: "good quality" butter might contain a substance, which confers it a Yellow commercial colour. Between butter with colorant and the same without it, many consumers choose the one with colour. There are several soft drinks (some very famous) which, without colorants, would have less success. The brain follows its ascending course towards the increase importance of symbolic models, so that, as we have seen it already happening, the decision in nutrition will be taken with more and more contribution from symbolic models. The guarantee exists on symbolic model, that, within the laws and the level attained by science and technology and the laws of economy, food is possibly the safest. Nutritional regulations can only impose what a certain product may not contain.
