The Hobbit’s Secret Weapon: Vitamin D

Hobbits.1

A couple of scientists have now determined why hobbits and elves usually win over orcs, even when they are severely outnumbered. The good guys’ secret weapon? Vitamin D.

This is of course a tongue-in-cheek statement. Being both a fantasy nerd and a Vitamin D nerd I find it quite funny.

However, imagine if it weren’t fantasy literature that was examined, but real history – perhaps the result would have been the same? What do you think?

    The "abstract" in the Medical Journal of Australia is a hilarious spoof on nutritional research papers.

    Tolkien rather stereotypically uses light to connote good and dark to connote evil, so as good/light triumphs over evil/dark, vitamin D repleteness triumphs over vitamin D deficiency.

    One might expect that the dairy and meat eating, low carb Mongols had a vitamin D advantage over the high-carb, grain-eating Jurchens. I have read the LCHF Mongols had an advantage over the carb-eating Jurchens that enabled the Mongols to outlast the Jurchens, since the Jurchens would have blood sugar lows hours after eating whereas the Mongols could go on and on and on without stopping to eat, and so were victorious.

    In the 1980’s we were told to replace our cooking lard with vegetable seed oils because lard was loaded with saturated fat. Lard from pastured pigs is second only to Cod fish liver oil in vitamin D content. Isn’t it ironic how many people are deficient in vitamin D nowadays ?
    Hmm, I wonder why ?

    It could also be the anti-inflammatory and energy-supporting effects of near-infrared (NIR) fraction of sunlight, not only the vitamin D production :)

    It would explain why the orcs have such bad teeth.

    If you are hungry and you know it; Eat some fat!

    If you are hungry and you know it eat some fat!

    If your hungry and you know it your diet should surely show it!

    If your hungry and you know it some fat!

    (2nd Verse)

    If your on a ketogenic diet and you know it eat low carbs

    If your on a ketogenic diet and you know it eat low carbs

    If you are on a ketogenic diet your eating habits should surely show it

    If you are on a ketogenic diet eat low carbs

    On a less lyrical note:

    Eric’s comment: Does this equate to HFLC is also good for our brains? (IMO yes!)

    High good and low bad cholesterol levels are healthy for the brain, too

    (SACRAMENTO, Calif.) -- High levels of "good" cholesterol and low levels of "bad" cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer's disease, in a pattern that mirrors the relationship between good and bad cholesterol in cardiovascular disease, UC Davis researchers have found.
    "Our study shows that both higher levels of HDL — good — and lower levels of LDL — bad — cholesterol in the bloodstream are associated with lower levels of amyloid plaque deposits in the brain," said Bruce Reed, lead study author and associate director of the UC Davis Alzheimer's Disease Center.
    The relationship between elevated cholesterol and increased risk of Alzheimer's disease has been known for some time, but the current study is the first to specifically link cholesterol to amyloid deposits in living human study participants, Reed said.
    "Unhealthy patterns of cholesterol could be directly causing the higher levels of amyloid known to contribute to Alzheimer's, in the same way that such patterns promote heart disease," he said.
    The study, "Associations Between Serum Cholesterol Levels and Cerebral Amyloidosis," is published online today in JAMA Neurology.
    In the United States, cholesterol levels are measured in milligrams (mg) of cholesterol per deciliter (dL) of blood. For HDL cholesterol, a level of 60 mg/dl or higher is best. For LDL cholesterol, a level of 70 mg/dL or lower is recommended for people at very high risk of heart disease.
    Charles DeCarli, director of the Alzheimer's Disease Center and an author of the study, said it is a wake-up call that, just as people can influence their late-life brain health by limiting vascular brain injury through controlling their blood pressure, the same is true of getting a handle on their serum cholesterol levels.
    "If you have an LDL above 100 or an HDL that is less than 40, even if you're taking a statin drug, you want to make sure that you are getting those numbers into alignment," DeCarli said. "You have to get the HDL up and the LDL down."
    The study was conducted in 74 diverse male and female individuals 70 years and older who were recruited from California stroke clinics, support groups, senior facilities and the Alzheimer's Disease Center. They included three individuals with mild dementia, 33 who were cognitively normal and 38 who had mild cognitive impairment.
    The participants' amyloid levels were obtained using a tracer that binds with amyloid plaques and imaging their brains using PET scans. Higher fasting levels of LDL and lower levels of HDL both were associated with greater brain amyloid — a first-time finding linking cholesterol fractions in the blood and amyloid deposition in the brain. The researchers did not study the mechanism for how cholesterol promotes amyloid deposits.
    Recent guidelines instituted by the American College of Cardiology, the American Heart Association and the National Heart, Lung, and Blood Institute have suggested abandoning guidelines for LDL targets. Reed said that recommendation may be an instance in which the adage that "what's good for the heart is good for the brain" does not apply.
    "This study provides a reason to certainly continue cholesterol treatment in people who are developing memory loss regardless of concerns regarding their cardiovascular health," said Reed, a professor in the UC Davis Department of Neurology.
    "It also suggests a method of lowering amyloid levels in people who are middle aged, when such build-up is just starting," he said. "If modifying cholesterol levels in the brain early in life turns out to reduce amyloid deposits late in life, we could potentially make a significant difference in reducing the prevalence of Alzheimer's, a goal of an enormous amount of research and drug development effort."

    The research was supported by grants P01 AG12435, AG034570 and P30 AG10129 from the National Institute on Aging of the National Institutes of Health. Villeneuve received support from the Canadian Institutes of Health.
    The UC Davis Alzheimer's Disease Center is one of only 27 research centers designated by the National Institutes of Health's National Institute on Aging. The center's goal is to translate research advances into improved diagnosis and treatment for patients while focusing on the long-term goal of finding a way to prevent or cure Alzheimer's disease. Also funded by the state of California, the center allows researchers to study the effects of the disease on a uniquely diverse population. For more information, visit http://alzheimer.ucdavis.edu
