An ounce of prevention is worth a pound of cure.

Albert Schweitzer began working in equatorial lowlands of West Africa in 1913. He was astonished to encounter no cases of cancer among the thousands of native patients he saw each year. However, as the natives [took to] living more and more after the manner of the whites, cancer in his patient population became ever more frequent (Taubes, 2016, pp 257).

Wise elders, grand parents or statesmen have been  traditional roles for aging adults. Wisdom transforming into Alzheimer’s disease does not compute (Peper, 2014).

In 1960’s Surgeon Captain T. L. Cleave proposed that common western diseases (diabetes, colon cancer, ischemic heart disease, gallstones, obesity, diverticulosis, and dental carries), to which I would add Alzheimer’s disease, autoimmune diseases and allergies, could not be due primarily to genetic factors but to new factors in the environment to which man had not yet had time to adapt (Cleaves et al, 1969). As he states, “One such factor was the processing of food which resulted in the consumption of large quantities of pure sugar and starch.  This led to disease because man was evolutionary adjusted to eating smaller amounts of carbohydrates intimately mixed with fiber and protein.”

Clinicians and epidemiologist have consistently reported that none western cultures, whether the Masai in Africa, the Inuit in Northern Canada, the Japanese in Japan, or the Native American, had very low incidences of these western diseases. Yet, when these people adapted a western diet of highly refined carbohydrates and sugar the prevalence of these diseases increased and approached the incidence in western cultures (Burkitt & Trowell, 1975; Taubes, 2016).

Historically these illness were initially observed in the ruling class.  The affluent class was privileged and tended to eat more refined carbohydrates and sugars (white bread, cakes, pastries and sugar in coffee and tea). It is only recently that this class effect is reversed. Lower economic classes tend have a higher prevalence of these western diseases.  Affluent people can afford and often eat low processed organic foods while economically disadvantaged people cannot afford low processed foods and instead eat predominantly highly processed carbohydrate and refined foods.

Highly refined processed foods and sugar–not fats–are  significant risk factors for the development diabetes and cardiovascular disease and mortality (Imamura et al, 2015; Taubes, 2016; Yang et al, 2014) . What is not as well known is that some cancers and Alzheimer’s disease also correlates with the increase intake of refined carbohydrates and sugar (Das, 2015; Kandimalla et al, 2016; Peper, 2014).

It is highly likely that the increase in beta-amyloid protein plagues in the brain is not the cause of the Alzheimer’s but the brain’s defense mechanism to protect it from the fluctuating high insulin and glucose levels. A high sugar and simple carbohydrate diet are risk factors for inflammatory diseases such as diabetes, heart disease and metabolic syndrome.  These inflammatory diseases are recognized as a precursor for Alzheimer’s. Alzheimer’s is sometimes described as Type 3 diabetes (Kandimalla et al, 2016; Steen et al, 2005).

Taking the perspective that foods are significant risk factors for the development of these western diseases, the focus should be on prevention and less on treatment.  The research to develop drugs to treat Alzheimer’s have up till now been unsuccessful despite that the billions spent on attempting to develop new drugs. For example, the pharmaceutical company Eli Lilly has spent 3.7 billion dollars over the last decade while the National Institutes of Health spends more than half a billion dollars a year on pursuit of treatment (Coghlan, 2017).

The treatments cost of these western diseases, which at best ameliorate the disorders, is overwhelming.  In the USA, we spent $147 billion to treat obesity and $116 billion to treat diabetes. While the medical costs to treat diabetes for a single patient is about $6000/year or $400,000/lifetime (Pollan, 2009).

As a refined carbohydrates and high sugar diet is a risk factor for western diseases, the focus should be on prevention. Thus, reduce sugar and refined carbohydrates intake and increase high fiber vegetable.  To implement such a simple preventative measure means:

  1. Educate the public about the harm of sugars and refined carbohydrate foods.
  2. Ban advertising of foods that are high in sugar and refined carbohydrates.
  3. Reward companies to produce foods low in sugar and refined carbohydrates.
  4. Tax food products high in sugar and refined carbohydrates just as tobacco has been taxed.

I am positive that in the future when we  look back at the 20th and early 21st century, we will be appalled that the government allowed people to poison themselves with sugar and highly refined carbohydrates. Just as we now warn against the harm of tobacco, limit the sales to minors,  and have ongoing public health stop smoking  campaigns.

Healthy movement is the new aging

Posted: February 11, 2017 | Author: | Filed under: Exercise/movement, self-healing, Uncategorized | Tags: , , , , , , | 2 Comments

Born on 26 November 1911, Mr Robert Marchand and 105 years old, managed cycling 22.55 km (14 miles) at the national velodrome and set a new record for the furthest distance cycled in one hour for riders over 105. (Reynolds, 2017).

Meet 105-year-old Robert Marchand, the centenarian cyclist chasing a new record: https://www.youtube.com/watch?v=Ey48j6dDNEo

As people age there is an increase in Western Diseases such as hypertension, diabetes, gout, cancer, dementia and  decreases in physical fitness (Milanović et al, 2013; Tauber, 2016).   To assume that the cause of these illnesses is the natural process of aging may be too simplistic. Although aging does affect physiology, there are other factors that contribute to the increase in “Western Diseases” such as diet, lifestyle and genetics.

A significant contributing factor of Western Diseases is diet especially  the increase in sugar and simple carbohydrates. Whether you are Pima, Tohono O’odham, and Navajo American Indian Tribes in Arizona, Intuits in Northern Canada, Japanese Americans, or indigenous populations of Kenya, when these people stopped eating their traditional diet and adapted the western high glucose/fructose/simple carbohydrate diet, the degenerative Western Diseases exploded (Bjerregaard et al, 2004; Burkitt & Trowell, 1975; Knowler et al, 1990; Tauber, 2016). Diabetes, hypertension, and cancer which were previously rare skyrocketed within one generation after adapting the Western life style diet. In some of these populations, 30% or more of the adults have diabetes and a significant increase in breast cancer.

The reduction of episodic high intensity physical activity and being sedentary are additional risk factors for the onset of diabetes and cardiovascular disease (Dulloo et al, 2017). As Mensing & Mekel (2015) state, “Sitting is the new smoking.”  Sitting encourages more sitting which leads to nonuse of muscles and causes neural and muscle atrophy.  Our physiology is efficient and will prune/eliminate what is redundant.  This is reflected in the popular phrase, “Use it or lose it.”  As we sit for hours in front of digital devices, use escalators, elevators, or drive cars, we are not using the muscles involved in dynamic movement.  We are usually unaware of this degenerative process. Instead,  we may experience difficulty walking up the stairs  which encourages us to take the escalator or elevator. When we do not use the muscles or are limited in movement by discomfort and pain, we move less. As we move less, we become  weaker which is often labeled as aging instead of non use.

Just, because most people loose fitness, it may not represent what is possible or optimum.  Instead, we may want to emulate the diet and fitness program of Mr. Robert Marchand who at age 103 set a new world record and improved the distance bicycled in one hour from 24.25 km at the age of 101 to 26.92 km at the age of 103. A 11% improvement! As New York Times science writer Gretchen Reynolds reports, “Lifestyle may also matter. Mr. Marchand is “very optimistic and sociable,” The researcher who did the study, Dr. Billat says, “with many friends,” and numerous studies suggest that strong social ties are linked to a longer life. His diet is also simple, focusing on yogurt, soup, cheese, chicken and a glass of red wine at dinner (Reynolds, 2017).

The improvement in bicycling performance and physiological indicators such as ⩒O2max increased (31 to 35 ml.kg-1min-1; +13%), appeared to be due to a change in his training regimen (Billat et al 2016).  At age 101 he changed his bicycling training program from riding at a steady speed for one hour to riding 80% at an easy pace and 20% at high intensity.  This is a  type of interval training and includes enough recovery allows the body the recover and strengthen. This analogous to our evolutionary movement pattern of walking interspersed with short distance high intensity running.

As a hunter and gather we often moved steadily and then had to run very fast to escape a predator or catch an animal.  After extreme exertion, we would rest and regenerate (if we did not escape we would be lunch for the predator). Thus episodic high intensity activity with significant rest/regenerative periods is the movement pattern that allowed our species to survive and thrive. Research studies have confirmed that high intensity interval training offers more physiological benefits–increases cardiorespiratory fitness which is a strong determinant of morbidity and mortality– than moderate intensity continuous training (Weston et al, 2014).

Thus when Mr. Marchard changed his exercise pattern from moderate intensity continuous training to high intensity interval training with enough recovery time he set a new world record at age 103. Two years later he set a new world record at age 105.

Exercise improves brain function and interval training appears to improve brain function most.  When rats had prolonged exercise, the brain’s stores of energy is significantly lowered in the frontal cortex and hippocampus all areas which area involved in thinking and memory. If on the other hand, the animals had a single intense bout of exercise and were allowed to rest and feed than the brain levels of glycogen was 60% high in the frontal and hippocampus areas.  This suggest that the brain can then function better (Matsui et al, 2012).

This perspective is supported by the evolutionary hypothesis discussed by Neuroscientist Daniel Wolpert who points out that brains evolved, not to think or feel, but to direct movement. When movement is no longer needed the brain shrinks and gets reabsorbed which is illustrated by the sea squirt. This animal swims as a juvenile and then anchors on a rock and is passively moved by the currents. Once anchored, it no longer needed to coordinate movement and reabsorb its own nervous system. See Daniel Wolpert’s remarkable TED talk, The real reasons for brains.

The remarkable feat of Mr. Marchand offers suggestions for our own health. Enjoy healthy movement and exercise and incorporate our evolutionary movement patterns:  episodic high intensity followed by regeneration. At the same time include a healthy diet by reducing sugars and simple carbohydrates.  Finally, it helps to have the right genes.
