The following is a direct quote from The current newsletter of the Permaculture Association UK: Permaculture Works (Vol II Issue 11 Autumn 2009) I would LOVE to hear your views particularly if you are a Permaculturist. Page 11 Your letters from Peter Wheat (direct quotes) 'What does a Permaculture Practitioner eat? Clearly local and vegetarian or Vegan, but the typical vegetarian diet is packed with things that only grow well in hotter countries (eg. soya, lentils, sesame, millet etc?) The other key consideration is getting balanced nutrition in terms of protein, carbohydrates and minerals. I would also be interested to know if any readers consider themselves expert in this area?' Peter Wheat End Quote: So Permaculturists what are the glaringly obvious problems here? Excellent answer Boho Garnet, but your information on B12 is actually incorrect. ALL vitamin B12 in the world comes from BACTERIA. Plants nor animals can synthesize it. Animal foods are rich in B12 ONLY because they eat plant materials contaminated by the bacteria. The amount of B12 we actually need is tiny about 3 MICROgrams per day, it is stored in the liver, tissues and kidneys for a long time (at least five years) you would have to be very persistently negligent to actually get B12 deficiency. The cases of B12 deficiency are usually found in meat eaters NOT vegans. Intestinal parasites compete for it, cigarette smoking can detroy it over time as can genetic problems of absorbtion. Very few Vegans actually get vitamin B12 deficiency because many grow their own foods/garden. It is the PROCESSING of manufactured foods whereby microorganisms are routinely washed off produce (with Chlorine) that eliminates the B12 bacteria. Such tiny amounts of B12 is needed that even if you (cont) home grown produce if you are eating it regularly it will provide the tiny amounts needed. Similarly, there is strong evidence to suggest that Vitamin B12 is lacking more in meat eating diets because of the Veggie/Vegan's awareness of diet and even if talking about manufactured vegetarian/vegan foods these are routinely fortified with B12 whereas manufactured mixed diet foods are not. see Davey G.K., Spencer E.A., Appleby P.N., Allen N.E., Knox K.H. and Key T.J. 2003. EPIC-Oxford: lifestyle characteristics and nutrient intakes in a cohort of 33 883 meat-eaters and 31 546 non meat-eaters in the UK. Public Health Nutrition. 6 (3): 259-69. (Continued) Research shows that B12 from fortified foods is better absorbed than B12 from meat, poultry and fish (remember meat eaters get their B12 from secondary sources the bacteria on the plants has to be eaten by the animals). Again numerous research articles confirming this including: Institute of Medicine. Food and Nutrition Board. Dietary Reference Intakes: Thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline. National Academy Press. Washington, DC, 1998. Alongside this there ARE other natural sources of B12 that CAN be found in a Vegan diet such as mushrooms grown outdoors (usually those sold as organic as they have not been subjected to chemicals in production or cleaning). Although fermented soya foods and seaweeds and yeasts don't provide a reliable source (quantity of B12 the same each time) including them in the diet does contribute significantly over time to maintaining high B12 levels.

A vegan/veggie 'permaculturist' would have to have ways of doing all the things that animals do within the ecosystem for it to be truly Permaculture and mimicking the natural ecosystem. Clearly vegan/veggie ethics about using animals for labour/pest control, using the yields expected from each (animal) element (fur, feather , excrement, urine, bone, blood, scratching, pest control, weed control/clearing, as food for other stock etc etc) prevents them copying ecosystems which contain animals that regulate/drive the ecosystem. This is the very essence of permaculture. A Permaculture Practitioner does NOT even eat local food UNLESS he can not provide it himself. Permaculture is about self sufficiency with limited trading with neighbours where needs can not be met BUT it is about self sufficiency of shelter, materials, fuel and dealing with wastes ALSO.
