Hi! My name is Albina Komissarova, and I'm a dietitian, endocrinologist.Why did I decide to write this book? I wanted to create a guide to the world of dietetics. Something like the ABC of healthy eating, after reading that, you will feel confident and easily be able to organize your own food and nutrition of your family without unnecessary restrictions and questionable techniques.It so happened that in the world of the Internet only lazy does not write about food. I don't know how a layman can figure this out! One writes one thing, the other another — where is the truth? And why should you believe this or that book?The answer to this question is one — only important evidence-based medicine and approach, systematizing and generalizing this knowledge.This book is a collection of proven knowledge that I have summarized, simplified and presented to you for the best understanding, providing a fraction of their own understanding of the subject.My colleagues may think that the medical language in the book is greatly simplified, called "instagram", but I wanted this book to be useful even for those who are little versed in medicine and science.We won't be able to talk about everything, touch on all the myths and misconceptions, but the experience of blogging has allowed me to isolate the most popular, interesting and controversial issues that need to be answered.I hope that after reading this book, the picture of the world of dietetics will be for you at least a little more clear.
