Garbage in, Garbage out!

This calculated progressive increase of food waste suggests that the US obesity epidemic may have been the result of a "push effect" of increased food availability and marketing with Americans being unable to match their food intake with the increased supply of cheap, readily available food.

America's Increasing Food Waste Is Laying Waste to the Environment

ScienceDaily (Nov. 25, 2009) — Food waste contributes to excess consumption of freshwater and fossil fuels which, along with methane and carbon dioxide emissions from decomposing food, impacts global climate change. In a new paper published in the open-access, peer-reviewed journal PLoS One, Kevin Hall and colleagues at the National Institute of Diabetes and Digestive and Kidney Diseases calculate the energy content of nationwide food waste from the difference between the US food supply and the food eaten by the population. The latter was estimated using a validated mathematical model of human metabolism relating body weight to the amount of food eaten.

The researchers found that US per capita food waste has progressively increased by about 50% since 1974 reaching more than 1400 Calories per person per day or 150 trillion Calories per year. Previous calculations are likely to have underestimated food waste by as much as 25% in recent years…READ MORE
