Here in Australia, everyone loves Dr Oz too! Recently Dr Oz interviewed Chris Kresser who is suggesting that dairy, beans and legumes are part of a Paleo diet. This is not so. Chris has just launched his book Your Personal Paleo Code, and we wish him success. Chris is a licensed acupuncturist and has a podcast show Revolution Health Radio which I highly recommend as a very interesting show if you are a podcast fan.
Prof Loren Cordain has written a rebuttal on legumes which outlines all the technical issues why and you can read this here. Beans and Legumes: Are They Paleo? This is a great summary of all the problems with beans and legumes. I also noted his past post about potatoes in response to other enquiries regarding other authors. I have some further comments below.
Like me, you may not have any serious illness (such as coeliac disease) that makes a strict diet necessary. Most of us are eating an UHG diet, that’s my name for an Urban Hunter Gatherer diet. Which means a fantastic diet, but we might slip in the odd glass of wine, chocolate, ice cream or other indulgence. Most people would still call this a Paleo diet, being 80 or 90% Paleo by calories with 10 or 20% palaver (in comparison Joe Average has 25% of diet as Paleo and 75% non-Paleo foods).
Paleo diet is a science, and proud of it. The usual definitions of Paleo are those you will find from researchers like Prof Cordain and Prof Staffan Lindeberg, the two of whom virtually established our current understanding of Paleo. They and their protegees, research teams and students are the source of power behind the explosion in understanding which has taken the world by storm. The correct definitions of Paleo found are in books by Prof Cordain, Robb Wolf and Ray Audette (Neanderthin was the first book outlining the current understanding, after Ray was advised by Prof Cordain, and managed to cure his diabetes and rheumatoid arthritis).
The real Paleo diet does not include dairy, beans/legumes, grains or potatoes. Commentators often compromise and sometimes, and say they are “allowable cheats” and some even go so far as to say that some of these are somehow Paleo. They are not. I suppose people should say “they are not Paleo, but a little bit won’t hurt most of us” (but not those with autoimmune disease or other serious health issues that may be caused by food). As for me, well I just admit that wine and chocolate and cheese and ice cream are definitely not Paleo, but they are less than 10% of my calories, and I am weak at times, and slowly slowly I hope to reduce them.
At least everyone agrees that wheat is not Paleo. Some people say dairy is Paleo- it’s not- a Paleo diet plus dairy is a pastoralist diet, and look where that got Ghenghis Khan- 2/3 of the known world! As for a Paleo diet plus potatoes, well please don’t ask me, I think the humble spud deserves to be humble. And beans and legumes, well sacre bleu! it is just not on.
There are several paths to get to a Paleo diet. The anthropologist path is based on research on hunter gatherers, the archeologist path is based on research on ancient man, or Ray Audette’s test (if was naked with a rock and a stick and no fire, could I have eaten it?) and several others. But one which I discovered early on in my journey (from 1999) and think is very important is the antinutrient test. Antinutrients is the term nutritionists use to describe toxins in everyday foods, probably because toxins or poisons does not sound nice, but that is what they are in every sense of the word. And what amazing toxins they are, with the ability to do tricks that no other known toxins can do, such as turn the immune system crazy.
Real Paleo foods have the lowest level of antinutrients of any nutritious foods. This is why a Paleo diet is the only true “detoxification” diet, all other diets are full of toxins, including most alleged detox diets. This also is why all Paleo foods can be eaten raw- at least in theory, you don’t need to feel obliged to do so. For a long time people ate a lot of foods raw. 10,000 years ago we started to eat toxic beans and grains, when it was discovered that cooking them first makes it possible to survive, though not thrive. Times were tough in those days, surviving was cool, they didn’t need Charles Darwin to tell them that, but the price of short term survival is long term health problems.
The worst sources of antinutrients are beans/legumes, and potatoes. Generally I would say that the worst legume in the Western world is the soy bean, followed by the kidney bean, then all the other beans. Green string beans are 90% husk and 10% seed, and only the seed part is harmful. If you want to know just how harmful some legumes in poor countries can get, read about lathyrism on Wikipedia and Google Images.
Beans/legumes and potatoes rival wheat for toxins. I regard beans as detestable. I can understand that people who have eaten lots of lentils might miss them. I used to like them myself. Once I went Paleo, I quickly found that I became very sensitive to an upset stomach and general tiredness after eating beans and lentils, so I am glad to stay off them. As for potatoes, my patients with gastroenteritis bugs seem to often link a recurrence to taking some potatoes, and I hope somebody researches that one day.
If you want to eat beans or legumes as part of your diet, that’s your right, but rest assured that it is not a Paleo diet. And they certainly do not pass the antinutrient test.
