In an 8 x 8 aluminium hut on a construction site outside Mumbai, Anchal Sahni sits down to dinner with her family: homemade aloo bhindo (okra and potatoes simmered in curry) and chapati (flatbread) with a side of lentils. Anchal has a healthier diet than many middle-class kids in India, who can afford to eat out. In Mumbai, a medium Dominoes pizza runs 13 bucks – about 3 times what Anchal’s father earns a day. Sensing a sea change in Western attitudes about diet and the effects of junk food, fast food companies have begun investing heavily in foreign markets where public awareness isn’t as keen – and Big Macs aren’t junk – they’re a status symbol. In 2015, Cambridge University conducted an exhaustive study, identifying countries with the healthiest diets in the world. 9 of the top 10 countries are in Africa, where vegetables, fruit, nuts, legumes, grains are staples and meals are homemade, a stark contrast to the US where nearly 60% of the calories we consume come from ultra-processed foods and only 1% come from vegetables. As globalisation alters our relationship to food, I’m making my way around the world, asking kids to keep a journal of everything they eat in a week. Once the week is up, I make a portrait of the child with the food arranged around them. I’m focusing on kids because eating habits, which form when we’re young, last a lifetime and often pave the way to chronic health problems like diabetes, heart disease and cancer.
