Algorithms are teasing apart the link between food and health to provide the first evidence that we really are what we eat.
Jean Brillat-Savarin was a 19th-century French lawyer famed for his writings on gastronomy. In his most famous work, he said: “Dis-moi ce que tu manges, je te dirai ce que tu es.” Or “Tell me what you eat and I will tell you what you are.”
This idea—that you are what you eat—has become increasingly popular. Since Brillat-Savarin’s time it has been used as the title of various cookbooks and health guides; for some it is a way of life.
