Food wastes in developed countries could nourish people dying of starvation in developing countries. This is the shocking truth revealed by a recent study by Kevin Hall of the National Institute of Diabetes and Digestive and Kidney Diseases of Maryland, published in the PLos One magazine.
Each American throws away a sufficient quantity of food (150 mln calories, that is nearly 40% of the food supply) to feed another person. The outcomes come just a few days after the disastrous conclusion of the FAO summit.

Researcher Kevin Hall used a different method than in the past to calculate food waste, which was usually estimated through consumer interviews or garbage inspections. The new approach was modeling human metabolism. Hall and his colleagues analyzed average body weight in the United States from 1974 to 2003 and figured out how much food people were eating during this period. Then they compared that amount with estimates of the food available for U.S. consumers: the difference between calories available and calories consumed, they say, is food wasted.

Compared to 1974, the food waste produced by each U.S. citizen has increased by 50%, being equivalent to 1400 kcal per person, totaling 150 million billion calories a year.
This means that every American is throwing away a quantity of food that could nourish another person in developing countries, as it is equal to almost three quarters of the daily requirement that is around 2000 calories.

Anytime we throw food away, we eventually did waste the water and petrol used for the production and transport of these foods. Moreover we contribute to increasing CO2 and methane emissions produced by food decomposition.
