Everyone talks about sugar. But the real problem is food culture (or the lack of). American, and now many European diets now consist of either fast food, oven-ready food or fried food. I recently went shopping and had a look at the "healthy" aisle. I could only find supposedly healthy food consisting of extremely savory dishes -carbonara, paella, etc. This is no way to eat healthy

In many western countries, no one is willing to eat a plate of barely seasoned boiled potatoes, or of barely seasoned pulses, etc

Everything is meaty, savory, rich.

Edit: I see I caused a reaction. I will explain. We are training our taste, and our children's tastes, to expect an explosion of flavor in every bite. This is not healthy. It promotes ordering take-out food, buying ready-meals, etc. Food doesn't need to be complex. We have fallen to "recipe book" diets. For example, I am mediterranean. When I read mediterranean recipe books, I see the same meals we eat, but turbo-charged with flavor. You can see the same thing in Chinese take-outs, where you will rarely see the owner eat the loaded meals he sells. He'll sautee some bean sprouts and mix them with boiled rice

Our stomachs aren't nuclear reactors, but in the western world, they are trained to be

Recipe book meals are ok to eat twice a week. The rest of the week should include steamed veggies with olive oil and salt, boiled apple puree, lentil soup, chick peas with carrots, mash with cabbage and til, leek and potato cream, etc
