Why good food is good for you
I don’t know about you, but I do sometimes wonder why (or do I mean how?) good foods are good for you. I know that they contain more things like anti-oxidants and vitamin precursors and vitamins and minerals, but I don’t have a very clear idea of how those things work their magic, if indeed they do. And then I was watching a Tedtalk by a chap called William Li, a doctor with a special interest in cancer.
He was talking about blood vessels and the extremely delicate balance that regulates the life and death of blood vessels in the body, and I realized that I could remember almost nothing about angiogenesis and the hormones that control it. Once I did. Then Li slipped into cancers, and showed that tumours depend for their survival on their blood supply. Cut it off, and tumours shrink. In fact, he said, we probably have loads of mini tumours popping up all the time, less than the size of the tip of a ball-point pen, but in the absence of a blood supply, they just wither and die. Fascinating, so there are fancy drugs that block the growth of blood vessels — antiangiogenesis drugs — and that offer a new approach to treating cancer. And those same drugs can treat obesity in mice genetically predisposed to eat until they become, in Li’s words, “furry tennis balls”.
And then he moved smoothly into diet. And lo, there were lots of foods, many of them them fruits and vegetables, that seemed to have potent anti-angiogenic activity in lab tests. Some of them, combined, are more potent than either on its own or both together. He listed a bunch of foods, and then something that made me perk up even more.
“For each food type, we believe there is different potencies within different strains and varietals. And we want to measure this because, well, while you’re eating a strawberry or drinking tea, why not select the one that’s most potent for preventing cancer?”
Wow. A man who starts from the assumption that not all varieties are equal. While I am not too happy with the continuing medicalization of nutrition and diet, treating good food as no more than a series of active ingredients, I am glad that at least someone in the medical establishment is taking agricultural biodiversity seriously. Li’s bottom line:
Everyone could benefit from a diet based on local, sustainable, antiangiogenic crops.
Nibbles: Hunter gatherers, Amaranthus and corn in Mexico, Protected areas and poverty, African ag, Pollan, Aquaculture in Laos, Range, Rainforest
- Pygmies forced to take up gardening, and they’re mad as hell about it.
- An amaranthus a day… And also from Mexico, saving maize from GMO nastiness. Oh, and the NYTimes does a number on maize domestication today to boot.
- Protected areas not so bad for people after all. But do they conserve biodiversity effectively? At least when community-managed, that is.
- African agriculture in theory and practice. Glib, I know. Get your own blog.
- Pollan does his usual shtick. But he does it well.
- You are subscribing to Danny’s nutrition thing, are you not? If you were, you’d know about the role of aquatic rice field species in rural Laotian diets.
- So how do you restore prairie? Expert opinion summarized and synthesized to within an inch of its life. But you can also hear from a range expert directly.
- Ok, so that’s grassland. If you wanted to restore a tropical rainforest you’d have to know about long-distance seed dispersal.
Nibbles: Land lease, Maasai flexibility, Small farms, Coffee, coffee, coffee, Climate change, Sahelian trees, Food as drugs, Field genebanks, Chinese medicinals, Bolivian NTFP, Invasives
- Dinka men despise manual labour, hence “southern Sudan might soon be on the block for having a lot of its potential farm land leased to, and worked by, foreigners”.
- Maasai, on the other hand, “diversifying into cropping, by keeping fewer and faster growing animals and … taking on paying jobs”. Takes all sorts.
- What is a small farm? Depends.
- Coffee contains insecticides. Who knew?
- Global Coffee Quality Research Initiative (GCQRI) launched.
- Central America’s coffee lands to shrink under climate change, Reuters reports. Enough! I’ve got the shakes.
- Africa, meanwhile, needs technological innovations to cope.
- Domesticating baobab. You know it makes sense.
- Take two snacks in the morning and call me if you don’t feel any better.
- Climate change will affect Portuguese ex situ plant conservation sites too.
- “How best can communities conserve their medicinal plants?” A case study from China.
- Bolivia could make more of its Araceae and Bromeliaceae. Couldn’t we all?
- Are protected areas in Africa harbouring crop wild relatives? Just kidding: it’s invasives IUCN is talking about.
Nibbles: Potato chemistry, Millennium Seed Bank, Sacred sites, Japanese festivals
- Measuring micronutrients and stuff in potatoes.
- Kew wants you to adopt a seed, save a species. Easy as that.
- Maybe religion can do some good in the world after all? Allow me to be skeptical.
- Wait, can I change my mind? The wonderfulness that is Japanese penis festivals. Well, they mainly take place in the spring. Agrobiodiversity mainly grows in the spring. There is a connection, surely.
