The first thing to understand about nutritionism is that it is not the same thing as nutrition. As the "-ism" suggests, it is not a scientific subject but an ideology. Ideologies are ways of organizing large swaths of life and experience under a set of shared but unexamined assumptions. This quality makes an ideology particularly hard to see, at least while it's still exerting its hold on your culture. A reigning ideology is a little like the weather--all pervasive and so virtually impossible to escape. Still, we can try.

One of the most irresponsible things we can do is eat in ignorance, without any awareness of what our eating is doing to the world or to other species.

Even people who like the kind of food on offer, are coming to recognize that eating from this food chain is not conducive to good health.

We could have a greener economy, even a greener consumer economy by changing the rules - whether it's by taxing carbon or trading carbon, I'm not sure what - but in the end there's just a fundamental problem with the sheer amount we're consuming.

This is part of human nature, the desire to change consciousness.

Measured against the Problem We Face, planting a garden sounds pretty benign, I know, but in fact it’s one of the most powerful things an individual can do - to reduce your carbon footprint, sure, but more important, to reduce your sense of dependence and dividedness: to change the cheap-energy mind.

Eat only until you're 4/5 full. An ancient Japanese injunction.
