Chapter 1
When Diet Leads to Illness
 
A child born today in an industrialized country can hope to live on average for nearly 80 years, a remarkable statistic considering that for the greater part of our history, life expectancy has been no more than 20 to 30 years (Figure 1). Only in the second half of the nineteenth century did life expectancy signifi cantly improve, continuing upward thanks to the amazing breakthroughs achieved by medical science during the twentieth century (Figure 2). In particular, the development of numerous antibiotics, vaccines, drugs, surgical procedures, and other medical achievements over the past 50 years has considerably reduced the toll taken by serious diseases, particularly those of the infectious kind. Barely a century has passed since tuberculosis, pneumonia, and diarrhea alone were responsible for one third of all deaths in the United States. These diseases today represent only a small percentage of deaths, well behind mortalities from "new diseases" such as cancer, cardiovascular disease, and other chronic conditions like Type-2 diabetes and neurodegenerative diseases (Figure 3). These illnesses therefore constitute the principal challenge faced by medicine today, well ahead of certain risk factors that often make headlines but whose real impact on public health is much less signifi cant (Figure 4).
 
Even though longer life expectancy has clearly played a role in the soaring mortality rates from chronic diseases, it is nonetheless worrisome that these diseases also strike people in their prime, considerably diminishing the duration and quality of life. For example, the World Health Organization (WHO) states that a person who lives for 95 years will lose an average of almost ten years of good health as a result of one or more of these chronic diseases. It goes without saying that the loss of independence and suffering resulting from the treatment of these diseases (surgery, chemotherapy, dialysis, etc.) represent a substantial loss of the benefi ts that should derive from a longer life span. Although the continued increase in life expectancy we have seen over the last 150 years suggests that average life spans could reach 90 or even 95 years in a few decades from now, this high incidence of serious chronic diseases threatens not only to halt the trend, but also to undermine the main reason for living longer: staying in good health for as many years as possible.
