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.

Some foods have significantly more Calories than others but what does the difference actually look like. Each of the photographs below represents 200 Calories of the particular type of food; the images are sorted from low to high calorie density. When you consider that an entire plate of broccoli contains the same number of Calories as a small spoonful of peanut butter, you might think twice the next time you decide what to eat. According to the U.S. Department of Agriculture, the average adult needs to consume about 2000 – 2500 Calories to maintain their weight. In other words, you have a fixed amount of Calories to “spend” each day; based on the following pictures, which would you eat?

What do you imagine when you look through a key hole? Do you imagine seeing a Wonderland with a sinister Queen of Heart ruling over a magical kingdom? Or you might imagine an eye staring back at you, if you’re a fan of horror movies. Least of all do you expect seeing a picturesque view of St. Peter’s Dome, perfectly framed by green hedges. Is it a lucky coincidence, or was it intended by the maker? We might never know. However, this became a curious sightseeing spot for many tourists who visit Rome. Thus, if you’re ever in the area of Priorato dei Cavalieri di Malta, be sure to peep into this key hole.

A burning flame and a broad expanse of water are among the few things which do not tire us with their beauty. However, while we have many sources of water around us, it is quite hard to marvel at a burning flame on a daily basis. Melissa Crisp is one of the few people who were able to subdue the element of fire. She is the person who is behind the design of the uniquely-shaped fire pits, which feature mystifying themes, including a pair of lovers, a fire on the rodeo arena, a forest fire, a fiery flower, and a number of others. Each of the fire pits entrances you, and it almost seems like the characters are alive, as the hot fire burns deep within the spheres, casting dancing shadows all around. (Photo by Melissa Crisp)
