There is a deliberate effort to undermine food culture to sell us processed food. The family meal is a challenge if you're General Mills or Kellogg or one of these companies, or McDonald's, because the family meal is usually one thing shared.

Oddly enough, government policy helped get the fast food outlets into the city. Very well-intentioned small business administration loans to encourage minority business ownership. The easiest business to get into is opening a fast-food franchise in the inner city.

The way you support farmers is by shopping and buying raw ingredients.

The first step in reforming appetite is going from processed food to real food. Then, if you can afford organic or grass-fed, fantastic. But the first step is moving from processed industrial food to the real thing.

I've been amazed to learn all of the links between microbial health and our general health. This all started by trying to understand fermentation. The fermentation outside your body, and its relation to the fermentation inside your body. The key to health is fermentation, it turns out.

Food choices are something fundamental you can control about yourself: what you take into your body. When so many other things are out of control and your influence over climate change - all these much larger issues - it's very hard to see any results or any progress. But everybody can see progress around food.

My whole interest in food grew from my interest in gardens and the question of how we engage with the natural world. To go back even further, I got interested in gardens because I was interested in nature and wilderness and Thoreau and Emerson.

You can have intense food experience with less food. Europeans have intense food experiences but eat less food.

When you realize the real pleasure in food comes in the first couple bites, and it diminishes thereafter, that's a kind of reminder to focus on the experience, enjoy those first bites, and as you get into the 20th bite, you're talking calories and not pleasure.

We know there is a deep reservoir of food wisdom out there, or else humans would not have survived to the extent we have. Much of this food wisdom is worth preserving and reviving and heeding.
