According to a study published in the journal PLOS One, food waste is linearly log-based to affluence, with a threshold of $6.70 per person per day. Researchers at the University of Wagningen in the Netherlands want to understand how how well consumers are rich affects food waste.
Using data collected by the World Health Organization and others, the researchers assessed the food purchased, consumed and wasted by consumers around the world. The authors found that Belgium had the highest rate of food waste and the Philippines had the lowest proportion of food waste.
It should be noted that the study covered two-thirds of the world,but did not include food-wasting countries such as the United States. Globally, each person wastes the equivalent of 527 calories a day, more than twice as many as scientists thought.
