Imagine a future where all food stores have 3 sections:

- The Green section (Food) - Natural food our ancestors would have eaten.

- The yellow section (Food-derived) - Things made partly from food, but in a factory, with huge servings of sugar, salt, and other artificial flavors -- granola bars, tomato sauces, etc.

- The red section (Calories) - Products that have calories but no nutritional value, no or negative impact on microbiome, indefinite shelf-life, >50% calories are refined sugar.
