A stunning photographic collection featuring portraits of people from 30 countries and the food they eat in one day. In this fascinating study of people and their diets, 80 profiles are organized by the total number of calories each person puts away in a day. Featuring a Japanese sumo wrestler, a Massai herdswoman, world-renowned Spanish chef Ferran Adria, an American competitive eater, and more, these compulsively readable personal stories also include demographic particulars, including age, activity level, height, and weight. Essays from Harvard primatologist Richard Wrangham, journalist Michael Pollan, and others discuss the implications of our modern diets for our health and for the planet. This compelling blend of photography and investigative reportage expands our understanding of the complex relationships among individuals, culture, and food.

Iraqi children play with a ball on a street blocked with burning tyres, amid a general strike in the southern city of Basra, on November 25, 2019. The demonstrations rocking the capital and Shiite-majority south since October 1 are the biggest grassroots movement the country has seen in decades.

A Palestinian fisherman casts his net as he stands along the beach in Khan Yunis in the southern Gaza Strip on June 14, 2019. The Israeli government said late on June 12 that the fishing zone off the coast of Gaza had been closed, in retaliation for the launch of incendiary balloons from the Palestinian enclave. The move came after COGAT said on Tuesday it had reduced the extent of the fishing zone to six nautical miles offshore from 10 nautical miles, having downscaled it from 15 nautical miles a week ago.
