Did our ancestors maintain a healthy diet? We might assume that at the very least they wanted to. People have always wished to be fit and, since times immemorial, they've known that their health depends on what they eat. But did they know ''how'' to? Was a healthy diet even possible before anyone ever heard of calories, vitamins, proteins, carbs, lactose, gluten, allergies and food intolerances?
