too little — and complex, because the manufacturing and marketing of food products has changed dramatically. Dr. David Kessler, former head of the U.S. Food and Drug Administration, has extensively documented how food manufacturers and restaurant and fast food chains carefully combine fats, sugar, and salt in precise ratios that reach the “bliss point” — which means they trigger brain systems that increase the desire to eat more, even after our stomachs are full. On a global basis, the World Health Organization has found a pattern of increased consumption of “energy-dense foods that are high in fat, salt and sugars but low in vitamins, minerals and other micronutrients.” Hyper-urbanization has separated more people from reliable sources of fresh fruit and vegetables. Quality calories in fruits and vegetables now cost ten times as much as calories per gram in sweets and foods abundant in starch. In a report for the Johns Hopkins Bloomberg School of Public Health, Arielle Traub documented the increase from 1985 to 2000 in the price of fresh fruits and vegetables by 40 percent, while prices of fats declined by 15 percent and sugared soft drinks by 25 percent.
