What have Weston Price, Ainslie Meares, Yoga & Meditation got in common
Weston Price is comparatively well known as the Dentist who travelled around the world in the 1930's and studied the diets of many cultures with far reaching findings. Less well known is the work of an Australian Psychiatrist, Dr Ainslie Meares (b1910-d1987). Dr Meares was a Founding Fellow of Royal Aust & NZ College of Psychiatrists and, for a time, the President of the Int. Society for Clin & Exp Hypnosis.
Like Weston Price, but in the 1950's-1960's, Dr Meares travelled around the world, witnessing and studying various mental states and the role these played in the lives of people from different cultures. In particular, he learnt an ancient method of meditation from a wise old yoga in Nepal who he describes as "different from any other man I have ever met" "he was serene" "When you were in his presence the calm of it was all through you" (Strange Places, Simple Truths pg25).
While respecting the value of traditional meditation, he developed a theory which differs significantly from meditation per se. His objective was to assist people in accessing the natural undisturbed calm within themselves. His method essentially consisted of treating his patients for anxiety, illness and pain by allowing the mind to rest.
He called this mental state atavistic regression. Some have misunderstood that term. Atavism which translates from Latin as "primitive". Regression means to go backwards. A better translation would be to use the word "primordial". Atvastic regression meaning returning to the original or elementary way that has existed from the very beginning. A return to a purer simpler state of mind- a mind free of disturbance. Meares definitely did NOT mean barbaric or uncivilised mind or anything like that.
He later changed to the term mental ataraxis to better communicate the idea of this mental state where there was a state of freedom from, and absence of, dis-stress and anxiety.
Many, many years before anxiety and stress were acknowledged as contributing to illness, Dr Meares had identified that. Long before the term mind-body medicine was coined, he emphasised it’s critical importance. And long before meditation was widely advocated as a potential means of healing, Dr Meares had established a solution to counteract mind- body distress.
It is believed that Meares meditation augments a natural physiological mechanism that restores ease to the mind. Undoubtedly, our hunter gatherer ancestors experienced this naturally as part of their way of life. Today, the search for it can be seen in the increasing numbers of Western people looking for answers in various Eastern practices. However, most of us are not Easterners. We are Westerners born in a Western culture with a Western mindset. Eastern mystics devote their lives to practice; they live for practice. By contrast, Meares Meditation (also called Stillness Meditation), is non-religious and non-sectarian. It was created as a mental restorative practice to assist modern Western people to live a better quality of life.

Is the Paleolithic diet 10,000, 100 or 15 years old?
They say there are no new ideas. Paleo - primal like diets have been around in one form or another for a long, long time. Listed below are some examples up until the year 2000 - after that much has been written.
Banting (1864). A letter on corpulence.
A smallish book on how to lose weight written by a grateful patient, given away and then priced at cost.
( While not pure paleo, the diet was in a paleo like direction ie consisted of natural meats, fruits, vegetables with dairy and grains excluded and small amounts of dry grape wine permitted (ie low sugar wine).
Stefansson, Vilhjalmur (1912). My Life with the Eskimo; The Macmillan Company, New York,
(He wrote several books but, this was the first)
Price, Weston (1939) Nutrition and Physical Degeneration: A Comparison of Primitive and Modern Diets and Their Effects Paul B. Hoeber, Inc; Harper & Brothers
I'm an Australian, so I have to mention:
Voegtlin, WL (1975) The Stone Age Diet. Based on In-depth Studies or Human Ecology and the Diet of Man. Vantage Press. Eaton, S; Shostak, M & Konner, M (1988). The Paleolithic Prescription: A Program of Diet & Exercise and a Design for Living. New York: Harper & Row.
Cordain, L (1999) The Paleo Diet: Lose Weight and Get Healthy by Eating the Foods You Were Designed to Eat.
(The first edition of the book that named the Paleo Diet and a good spot to end this post)

[ Paleolithic = Stone Age = Cave Man = Hunter Gatherer = Garden of Eden ] Diet
You can call it:
- Paleolithic Diet
- Stone Age Diet
- Cave Man Diet
- Hunter-Gatherer Diet.
- Garden of Eden Diet
- any other name you like or that sounds distinctive
Some supposed version mention beans, potatos, butter, hard cheeses etc, etc. Some say you have to eat bucket loads of meat. Others mention eating an ever varying range of foods. Then some say it has to be organic or slow food or you have to drop out and grow it all yourself.
Who is right?
Assuming that you want your diet to bear a strong resemblance to what was eaten during paleolithic times (ie before agriculture) and in a manner consistent with modern hunter gatherers then:
Say NO to
NO grains and cereals including bread, noodles and pasta
(try picking and eating raw wheat)
NO dairy
(try and milk a large wild, horned herbivore that has young suckling, if you survive you will understand. Anyway, you are a human being and not a baby herbivore trying to grow into a cow and so drinking filtered cow's blood is not the way to go.)
NO peanuts - they are legumes and are different to tree nuts
NO Beans (legumes) eg string beans, kidney beans, lentils, peanuts and peas
NO added refined sugar, no added salt, no refined vegetable oils.
---------------------------------------------------------------------
Say YES to
- natural pasture fed meats (NOT grain fed), seafood, organ meats like liver, kidney etc
- eggs
- fruits and berries
- vegetables (NOT potatos).
- tree nuts eg. walnuts, brazil nuts, macadamia, almond. NO peanuts (a bean\legume)
- olive, walnut, flaxseed, macadamia, avocado, coconut oils
What are the effects of making these changes? :
- a big increase in nutrients
- a significant reduction in toxins
- a decrease in carb\sugar content so you will burn carbs AND fat
If its not on the list you can't eat it.
You can "flavour" dishes using small amounts of herbs
and use healthful oils (see above) for cooking as well.
How do I know this is information is right?
Read up on your archaeology and anthropology, understand how botany and technology influence the ability to utilise foods, appreciate optimal foraging theory. If you want to do some modern pseudo experimental archaeology (also called first hand experience) take up farming, fishing, hunting and growing your own fruit and vegetables as an experiment. If you are an Australian maybe you could go walkabout... or learn about it.
Read up from reputable sources. If you do these things, I guarantee that the following foods will be on the menu:
pastured meats, organs, seafood, eggs, fruits & berries, vegetables, tree nuts.

Potatos Taters and Spuds are NOT pure Primal - Paleo cuisine
Yes, its true, potatoes are not primal - paleo. This post provides an overview about why this is the case.
The potato (solanum tuberosum) plant is a nightshade that originated from South America. Genetic testing of cultivars and wild species indicate a single origin for potatoes in the Peru - Bolivia area about 7,000–10,000 years ago. The plant was introduced into the outside world including throughout Europe only 400 years ago!
The average (non-paleo) Western person is said to eat 30+ kg of potato each year!
Potatos contain a high glycemic load and high glycemic index. The glycemic index is comparable to refined sugars. This is not a good thing and just as refined sugars are associated with various diseases so to are potatos for similar reasons.
Potatoes contain toxic compounds known as glycoalkaloids including the saponins: solanine and chaconine. These antinutrients (ie poisons) protect potatos from microbes and insects that consume these "seeds" by dissolving cell membranes. Saponins will exert similar effects in humans consuming them. In humans, consumption of glycoalkaloids, or substances containing them, will cause headaches, diarrhoea, cramps, and in severe cases coma and death. Poisoning from potatoes has occurred and is probably underestimated. The symptoms of glycoalkaloid poisoning eg cramps, diarrhea with some headache is similar to microbial food poisoning symptoms and could be confused with that. Sometimes, it might not be the take away chicken (eg chicken and chips) or the seafood (eg seafood and chips) that was off. It might be the potatos contained higher amounts of saponins.
Glycoalkaloid content in potatos is increased by exposure to light, physical damage and age. The green colour is not a reliable guide to saponin content ie if it ain't green it can still contain significant amounts of saponin.
Cooking at high temperatures, over 170 °C reduces gylcoalkaloid content but, depending on the original concentration prior to cooking, substantial quantities may remain. So, fire is also needed before significant consumption of potato can occur that will mostly avoid acute toxicity ie temporary or permanent adverse effects shortly after eating (including death). No one should ever eat raw potato. But through avoiding light and through cooking may not be sufficient.
While cooked potato flesh has 20-200 mg/kg of glycoalkaloid, a cooked green tuber contains ~250+ mg/kg, and cooked skins ~1500 mg/kg. 200mg/kg was used as a safety standard by the industry for many years but, many scientists believe that the figure should be substantially reduced perhaps to around ~50mg/kg. You can see that many potato foods will exceed these numbers. Google around if you want more data around this theme.
Potato glycoalkaloids increase intestinal permeability, which allows foreign compounds to gain access to the blood and body tissues, and if consumed over a long time this will contribute to chronic inflammation and associated diseases such as cancer, autoimmune disease, cardiovascular disease and diseases arising from insulin resistance.
Potatoes also contain significant amounts of lectin. This lectin almost certainly resists degradation by gut enzymes, passes thru the gut barrier and bind tissues inside our bodies. It is believed that lectins such as potato lectin play a role in autoimmune and allergic processes.
It is to be noted that from the bodies perspective it is always the total dose that is important. So, in relation to intestinal permeability it is the total dose of substances that increase intestinal permeability (eg saponins, gluten (wheat etc) etc) and those factors that tend to reduce intestinal permeability (eg vitamin D via zonulin tightens up junctions between intestinal lining "barrier" cells). Similarly, in relation to lectin load it is the total body load that is important and lections are found various other foods eg gluten is also a lectin.
In summary:
- humans only domesticated the potato 7,000 to 10,000 years ago, in a smallish part of the South American continent and consumption would have been limited to a few months of the year due seasonal nature of crop and hazards of storage (ie increased saponins). Widespread distribution and consumption of the potato by European humans has only occurred for <400 years.
- potato's have a glycemic index as high as refined sugar.
- potato's contain saponins and lectins in sufficient amounts to exert chronic effects over a period of time including reduced intestinal permeability, chronic inflammation etc
Verdict:
Potato's are not paleo. Optimists can reserve them as a treat ie the 10-15percent of "fun" foods that some versions of the paleo - primal diet permit........ If you have any susceptibility to active disease processes, particularly if increased intestinal permeability, chronic inflammation, allergy\ immune response, hyperinsulemic response etc are component then potatos are likely to exert an additive or synergistic effect in relation to other risk factors.
Why not find a substitute for potatos? For example, sweet potatos, pumpkin, carrots etc do not contain significant quantities of lections or glycoalkaloids and have lower glycemic index values.
