The dietary energy supply is the food available for human consumption, usually expressed in kilocalories per person per day. It gives an overestimate of the total amount of food consumed as it reflects both food consumed and food wasted. It varies markedly between different regions and countries of the world. It has also changed significantly over the 21st century. Dietary energy supply is correlated with the rate of obesity.
Famous quotes containing the words energy and/or supply:
“Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called “self-interestedness.” This was not a portrait of man “warts and all.” It was all wart.”
—George F. Will (b. 1941)
“Dear to us are those who love us ... but dearer are those who reject us as unworthy, for they add another life; they build a heaven before us whereof we had not dreamed, and thereby supply to us new powers out of the recesses of the spirit, and urge us to new and unattempted performances.”
—Ralph Waldo Emerson (1803–1882)
