Food has always been a big part of our lives. In the past it was either an object of constant worry for the poor, or a way for the rich to enjoy life through over-indulgent eating. Only in the past century have people started wondering about the healthfulness of our meals, and how food production is affecting the planet. Initially they were concerned about body image and health, the rising threat of cholesterol-related diseases and obesity, and finally people became aware of the dangers of unsustainable food production for future generations.
