Thousands of books have been published on the effect of diet on health. But among them is dominated by books on diets for weight loss, because it is obesity is now one of the main problems for the population in Western countries. Many books have been published about nutrition to advertise a particular commercial product or a particular theory of aging. I do not set such a goal, and try to create a more general "gerontology nutrition" tips which can be followed in different conditions. In this book I have touched on only a portion of the key issues of diet and lifestyle, and I hope to continue this analysis in the near future. My wish to readers is that they are not addicted to advertising appeals restaurants and supermarkets, for which food is primarily a means of profit. Readers should understand the physiological benefits of a well balanced and varied diet, consisting of the components we use to constantly reproduce your own body. The more precisely we do it, the longer we live.
