Tomorrow's population will be larger, heavier and eat more,
Norwegian University of Science and Technology, November 9, 2018.


“An average adult in 2014 was 14 per cent heavier, about 1.3 per cent taller, 6.2 per cent older, and needed 6.1 per cent more energy than in 1975. Researchers expect this trend to continue for most countries.”

"An average global adult consumed 2465 kilocalories per day in 1975. In 2014, the average adult consumed 2615 kilocalories."

“Globally, human consumption increased by 129 per cent during this time span. Population growth was responsible for 116 per cent, while increased weight and height accounted for 15 per cent. Older people need a little less food, but an ageing population results in only two per cent less consumption.”

"The additional 13 per cent corresponds to the needs of 286 million people."

“Weight gain per person from 1975 to 2014 ranged from 6 to 33 per cent, and the increased energy requirement ranged from 0.9 to 16 per cent.”

“The lowest and highest changes are found in Asia and Africa, reflecting the disparities between the countries of these continents.”

“Most studies estimate that an average adult's food needs remain constant over time and fairly similar across nations. But that's not how it is.”

"These assumptions can lead to errors in assessing how much food we'll actually need to meet future demand."
