Archery and the primal paleo diet

In the video link below some archery is demonstrated based on practical research.... years of it. He looked at the data and did some experiments and then looked for more information etc. Round and round the process of research, do, evaluate, research, do evaluate went on and this is the spectacular result.

The work sheds new light on recent historical battles where archery played an important role such as Crecy, Hastings, the Crusades etc. These archery techniques were known to the Egyptians and were probably around back into the paleolithic period. Because techniques are software unlike the hardware (eg pictures of archers, bows, arrows etc) it is easy to underestimate the level of sophistication of archery.

Apply this example to other physical artefacts left by our paleolithic ancestors and its easy to see that we tend to underestimate their level of sophistication. Any quick reading of readily available information makes it obvious that hunter gatherers have an encyclopaedic knowledge knowledge of edible plants, herbs, animals, weather etc. If you read around you can also see information that indicates that many of these people new about nutrition ie eating a preys eye and associated tissues cures human blindness due to vitamin A deficiency etc/ But, the archery information was a surprise to me and I wonder what else our paleo ancestors knew about that we have not recognised.

Anyway, here is that clip:

The devil Gout and the primal paleo diet

I know an elderly person who suffers from the gout and so did a bit of looking into it.

Gout is a well known disease that was rare until last century. Prior to that it afflicted the rich and wealthy. The symptoms of gout are caused by a buildup of uric acid crystals in various joints- particularly the feet, ankle or knee but, can be present in any other joint. Gout is associated with various other conditions eg high blood pressure, heart disease, diabetes, obesity and increased blood triglycerides, increased small dense LDL cholesterol and decreased HDL cholesterol.

Gout is unknown in hunter gatherer societies. For those familiar with the primal - paleo diet the above picture will sound familiar- ie unknown in primitive societies, rare in the west till after the industrial revolution, greatly increased incidence in the last few decades.

Uric acid crystals cause the inflammation\pain in gout. So, more uric acid can arise from

• eating more of it (or things made into to it)
• making more of it
• excreting less of it.

It is the balance that is critical ie for uric acid to build up input must be greater than output (loss).

• turnover of purines - 2/3 uric acid arises from turn over within the body
• eating meat and shellfish
• about 1/3 of dietary purines
• meat and shell fish are largely protein which increases uric acid excretion by kidneys.
• eating carbohydrates (grains and refined sugars) increase uric acid synthesis in liver and reduce its excretion by kidneys
•  eating protein increases uric acid excretion by kidneys. This includes protein from meat and shellfish.
•  alcohol increases uric acid production and reduces its excretion.

It is well known that gout patients under excrete uric acid from the kidneys. It should be no surprise to learn that insulin inhibits uric acid excretion by the kidneys and that a higher carbohydrate diet will result in greater levels of insulin production. Remember gout patients usually have diabetes (or are pretty damn close) have insulin resistant cells and so must synthesise a lot of insulin. A person with insulin resistance (ie secreting large amounts of insulin due to cells less sensitive to insulin) and on a high carbohydrate based diet would be expected to build up uric acid.

This would all seem to indicate a higher protein diet, reduced high glycemic index\load carbohydrates (eg no grains but vegetables with some fruit). One trial of this was done and published in 2000. Back then, the idea of high protein diet replacement drinks was considered radical and needed a prescription in some countries. Now you can buy them off the shelf at your local chemist or supermarket. Times change. It be no surprise to learn that using a paleo diet for gout is not widely known and the most widely recommended gout diet is based on limiting protein and increasing grains and refined sugars foods. This is also well known to have only a small effect, if any, on the gout which is usually described as "difficult to treat".

The reference for that small published trial is:
Dessein, Shipton, Stanwix, Joffe, Ramokgadi (2000) Beneficial effects of weight loss associated with moderate calorie/carbohydrate restriction, and increased proportional intake of protein and unsaturated fat on se rum urate and lipoprotein levels in gout: a pilot study. Ann Rheum Dis59(7):539-43.

 

There may be other trials out there as well. Researchers out there.... there may be an oppurtunity here for a clinical study of paleo diet for gout sufferers or if you are very conservative a somewhat higher protein, low glycemic index, low glycemic load trial for gout sufferers. Mediterranean would be expected to work better than the conventional western diet but a primal paleo diet would be expected to work better.

 

Now many gout sufferers are elderly, although, gout does also affect young persons. Gout sufferers often, as outlined above, may be suffering several disease and may reap significant benefits from a paleo diet and life pattern. In these cases, "to much, to soon" can be as much as problem as "to little, to late". Medications will need to be monitored and may need to be reduced over time by your doctor (who you have told about your dietary changes etc and knowing your full diagnosis\history etc is keeping an eye on his\her patient). A conservative, gentler approach could be to transition across to a paleo -primal diet over weeks rather than the "its Paleo Day 1 today" approach. An example of one way this could be done is by shifting to lower glycemic index\load foods (ie cutting back on grains\dairy and shifting to vegetables and some fruit) with meat\eggs\shelfish\fish served as a portion in every meal (including breakfast- as the conventional diet often lacks breakfast protein) ie a Mediterranean style diet for a couple of weeks and then transitioning to a paleo - primal diet. There are various methods which could be applicable but in all cases there is a need for medical input and monitoring.

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.

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).
