I think that after graduation of this course it is not possible not to change opinion on what people usually eat. Everyday overload of advertisement significantly warps opinion of what is beneficial for human being. They work on principle that lie repeated hundred-times becomes the truth. After graduation of this course every participant has to change at least his diet. Every lesson brings more and more questions. So, I watch with a smile an offer of other courses that promise managing of this topic within one week or even weekend. Further development of gained information is very important. And it is not important if you will or will not make your living on consultancy after graduation of this course. Prolongation of life and avoiding diseases due to bad diet are worth this investment.
