Corn is a greedy crop, as farmers will tell you.

You know what a lima bean does when it's attacked by spider mites? It releases this volatile chemical that goes out into the world and summons another species of mite that comes in and attacks the spider mite, defending the lima bean. So what plants have - while we have consciousness, toolmaking, language, they have biochemistry.

At home I serve the kind of food I know the story behind.

We are the species who cooks. No other species cooks. And when we learned to cook, we became truly human.

You can make real food in 20, 30 minutes, but we've convinced ourselves that it is a rocket science. It's a shame. It's the media and the food industry: they've fed our panic around time.

A cow out on grass is just an incredible thing to behold... Cows and other ruminants can do things we just can't do. They have the most highly evolved digestive organ on the planet, called the rumen. And the rumen can digest grass. It takes grass, cellulose in grass, and turns it into protein, very nutritious protein. We can't do that.

Eat food. Not too much. Mostly plants. That, more or less, is the short answer to the supposedly incredibly complicated and confusing question of what we humans should eat in order to be maximally healthy.

It's not food if it arrived through the window of your car.

Corn is an efficient way to get energy calories off the land and soybeans are an efficient way of getting protein off the land, so we've designed a food system that produces a lot of cheap corn and soybeans resulting in a lot of cheap fast food.

To a very great extent, it's the fast-food industry that really industrialized our agriculture - that drove the system to one variety of chicken grown very quickly in confinement, to the feedlot system for beef, to giant monocultures to grow potatoes. All of those thing flow from the desire of fast-food companies for a perfectly consistent product.

Simply by starting to cook again, you declare your independence from the culture of fast food. As soon as you cook, you start thinking about ingredients. You start thinking about plants and animals and not the microwave. And you will find that your diet, just by that one simple act, that is greatly improved.

The larger meaning here is that mainstream journalists simply cannot talk about things that the two parties agree on; this is the black hole of American politics.

Before I started writing about food, my focus was really on the human relationship to plants. Not only do plants nourish us bodily - they nourish us psychologically.

As a society, we devalued farming as an occupation and encouraged the best students to leave the farm for 'better' jobs in the city. We emptied America's rural counties in order to supply workers to urban factories.

If you made all the French fries you ate, you would eat them much less often, if only because they're so much work. The same holds true for fried chicken, chips, cakes, pies, and ice cream. Enjoy these treats as often as you're willing to prepare them - chances are good it won't be every day.

While the surfeit of cheap calories that the U.S. food system has produced since the late 1970s may have taken food prices off the political agenda, this has come at a steep cost to public health.

Specialization makes it easy to forget about the filth of the coal-fired power plant that is lighting this pristine computer screen, or the backbreaking labor it took to pick the strawberries for my cereal, or the misery of the hog that lived and died so I could enjoy my bacon.

We love salt, fat and sugar. We're hard-wired to go for those flavors. They trip our dopamine networks, which are our craving networks.

The correlation between poverty and obesity can be traced to agricultural policies and subsidies.

I can probably earn more in an hour of writing or even teaching than I could save in a whole week of cooking. Specialization is undeniably a powerful social and economic force. And yet it is also debilitating. It breeds helplessness, dependence, and ignorance and, eventually, it undermines any sense of responsibility.

Meat is a mighty contributor to climate change and other environmental problems. The amount of meat we're eating is one of the leading causes of climate change. It's as important as the kind of car you drive - whether you eat meat a lot or how much meat you eat.

McDonald's is in a unique position. They can decide they don't want meat with hormones in it, and that will be the end of hormones in meat. I actually think exerting pressure on McDonald's is probably just as important as on the Department of Agriculture.

I like the taste of grass-fed meat. It is chewier, I'll own that... The Argentines make excellent beef that's grass-fed. They've learned how to age it, and they've gotten good at it.

Species co-evolve with the other species they eat, and very often, a relationship of interdependence develops: I'll feed you if you spread around my genes. A gradual process of mutual adaptation transforms something like an apple or a squash into a nutritious and tasty food for a hungry animal.

My mode as a writer is to layer different perspectives: the scientific, the philosophical, the political, the journalistic. When you layer them, you get a really wholesome, interesting picture.

I'm very picky about the meat I eat. I eat grass-fed beef, which is now becoming more common. Yes, it's still more expensive, but it's a very sustainable product.

Raw foodists are kind of paddling upstream against evolution. The only reason they can do it, and they don't all keel over, is that they are using blenders. They're very Cuisinart-dependent.

Don't eat anything that won't eventually rot.

The things journalists should pay attention to are the issues the political leadership agrees on, rather than to their supposed antagonisms.

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.

Bayer's planned acquisition of Monsanto promises to increase concentration in both the seed and agrochemical markets.

For at the same time many people seem eager to extend the circle of our moral consideration to animals, in our factory farms and laboratories we are inflicting more suffering on more animals than at any time in history.

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.

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.

It's not as if I've ever been to prison or been close to going to prison. The closest I've got is knowing people who have been in jail - after all, I was a member of Parliament - and visiting them there during their sentence.

I have Spanish ancestry and, indeed, speak the language, up to a point.

You never quite know what you do in life that leaves a seed behind that grows into an oak tree.

Music turns the world upside down.

What's extraordinary about Cobra Mist, and so much of what went on at Orford, was that the public were completely oblivious to it.

Travelling the railways of Europe with a century-old guidebook can be disconcerting: fares, food, and drink seem shockingly expensive compared with what they were; trains and paddle-steamers run to unexpected timetables (assuming they're still running at all); and not only states but whole empires have been wiped from the map.

Personal responsibility matters.

I do rather rejoice when people come up to talk to me about railways.

I look back on my schooldays with a warm glow of nostalgia.

Three letters send a chill down the spine of the enemy: SAS. Those letters spell out one clear message. Don't mess with Britain!

I don't think I've got a thick skin, but I've not felt particularly humiliated by the things which people think I would have felt humiliated by, such as losing my seat in 1997 and not being elected leader in 2001. In the second case, I felt relieved.

My favourite British line is the West Highland line. It was built across moorland where no one had succeeded in building a road. So everything in that area is there because of the railway line.

People are obviously very interested in travel, including travel in Britain.

No restaurant, however brilliantly situated, can give you the constantly changing views that you can see from a railway. Revolving restaurants at the tops of tall buildings try to compete, but spinning around is no substitute for speeding along.

My Scottish grandfather, John W. Blyth, was a man addicted to paintings. A manufacturer of linen, he spent all his surplus money on pictures.

My grandfather, who was always keen to promote living artists, staged an unprecedented exhibition of Peploe's works at Kirkcaldy in 1928.
