Low-energy diets render motor neurons vulnerable to degeneration

This paper is a bit old but I am posting it to keep it in focus for a discussion.   Please notice that low fat vegan diets often tend to be "low energy"!

Mattson MP, Cutler RG, Camandola S. Energy intake and amyotrophic lateral sclerosis. Neuromolecular Med. 2007;9(1):17-20


Roy Walford, a physician and scientist who pioneered research on the anti-aging effects of caloric restriction and subjected himself to a low-energy diet, recently died from amyotrophic lateral sclerosis (ALS). Information from his case, epidemiological findings, and recent controlled studies in mouse models of ALS suggest that low-energy diets might render motor neurons vulnerable to degeneration, whereas high-energy diets are ameliorative. This contrasts with the effects of low-energy diets on various neuronal populations in the brain that respond adaptively, activating pathways that promote plasticity and resistance to disease. One reason that motor neurons might be selectively vulnerable to low-energy diets is that they are unable to engage neuroprotective responses to energetic stress response involving the protein chaperones, such as, heat-shock protein-70 [*].


*) In addition to that, ketone bodies (often very low on low-energy diets) would have been protective against neural damage caused by the stress response, see:

This video illustrates what kind of diet did Dr. Walford followed for about 10 years before his death (see around 7m into video). 

Vegan promoter warns vegans against Parkinson's!


This is 2 years old, I just rediscovered it in my heretical files.  Worth reading.


From Dr. Fuhrman's latest e-mail [around Apr 02, 2009] :

Leaders of the Vegan Movement Develop Parkinson's: Case Studies

Herbert Shelton (1895 - 1985) a naturopath and chiropractor and the influential founder of the American Natural Hygiene Society and Nature Cure movement in America and prolific health writer advocated a natural food vegetarian diet of mostly raw fruits, vegetables and nuts. I read all of his highly motivating books, newsletters and writings in my teens. He lived in Texas, was physically fit, grew lots of his own food and ate carefully and fasted periodically. Of course he did not get cancer, he did not get heart disease, but he died of Parkinson's disease and was so severely affected by the age of 78 that even walking was difficult. In 1973 when I met him he was already severely hunched over and had a difficult time walking and caring for himself. Though he lived many years with this significant disability, the quality of his later years was extremely poor.

Prominent Vegetarian and Health Advocate - this leader in the natural health movement and a personal friend to me also suffered from and eventually died from a fall related to his Parkinson's disease. During his young adult life he embarked on the path of healthy living and vegetarianism. A follower of Shelton's works, he operated a large health food store, one of the first to sell organic fruits and vegetables in America; he became a leader in the health food industry. Of course he was not at risk of cancer or heart disease with his excellent diet, but he developed Parkinson's which limited the quality of his later years.

When he was developing his Parkinsonian tremors, I ordered blood tests and was shocked to see his blood results showing almost a zero DHA [*] level on his fatty acid test, in spite of adequate ALA consumption from nuts and seeds eaten daily. I had never seen a DHA level that low before. Since that time I have drawn DHA blood levels on other patients with Parkinson's and also found very low DHA levels.
Was it a coincidence, that these leaders in the natural food, vegetarian movement, who ate a very healthy vegan diet and no junk food would both develop Parkinson's? I thought to myself--could it be that deficiencies in DHA predispose one to Parkinson's? Do men have worse ability to convert short chain omega-3 into long chain DHA? Is that why Parkinson's affects more men than women? Is there evidence to suggest that DHA deficiencies lead to later life neurologic problems? Are there primate studies to show DHA deficiencies in monkeys leads to Parkinson's? The answer to all of these questions is a resounding, yes.

*) DHA - Docosahexanoic acid, omega-3 type of fat commonly present in animal produce, especially in brain, spinal cord, nerves and egg yolks.  This type of fat is generally not present in plant based products, with very few exceptions (some algae).

In addition, a high carb nutrition would probably offer less natural protection against neuro degenerative diseases because of low level of ketone bodies.  For example non-ketogenic diet would be less protective against stress-induced neural damage, see:  Ketone bodies protect neurons from stress hormone-induced damage

46% sugar diet causes breast cancer...


Underfunded Scientists Force Lipstick-Covered Rat With Cancer To Run Through Maze

... in mice, as medical "scientists" have recently discovered in this study.   Strangely, that is not what they officially concluded, that's why I put the word in quotes!   The lethal mice diet consisted of 46% of sugar (31% sucrose + 10% maltodextrin + 5% dextrin), 21% of milk fat and 19% of casein.   Read more about that in this post by Denise Minger.

Low fat diets could increase heart disease risk...

... say nutrition experts.

Home-made(*) pork lard. Obviously, it has to be good!

Saw this article link on THE SPARK OF REASON blog (thanks!).

The article describes a symposium called "The Great Fat Debate: Is There Validity In the Age-Old Dietary Guidance?" at the American Dietetic Association’s (ADA) Food and Nutrition Conference and Expo. It would have been a usual boring scientific waffle following a vacuous hedge-all-bets type of philosophy, had it not been for some quotes of Dr. Walter Willett's presentation. He is one of the few prominent medical officials (director) not following the "speak but say nothing" strategy. At least not since a couple of years ago.

Quotes (of Dr.W.Willett):

"If anything, the literature shows a slight advantage of the high fat diet," he said. "The focus on fat in dietary guidelines has been a massive distraction. ... We should remove total fat from nutrition facts panels on the back of packs."

He added that while the pervasive dietary guidance given to consumers has been to eat fats sparingly, to load up on starch and eat non-fat products, "the food industry quickly realized sugar was cheaper than fat and laughed all the way to the bank."

And assistant professor of medicine at Harvard Medical School Dr. Mozaffarian:

... agreed with the other speakers about a lack of evidence linking total fat consumption and cardiovascular disease risk.

*) Chop pork belly into finger-sized slices or mince, put in a slow-cooker overnight, sieve-out the cracklings from liquid lard, while hot. Pour to plastic tubs. Feed the cat.
