    "What Are Nutritional Diseases?

    In their book, The Modern Nutritional Diseases, Fred and Alice Ottoboni, retired Public Health Service scientists, list the following.
    * Obesity
    * Diabetes II
    * Cardiovascular Diseases
    * Stroke.
    * Cancer.

    Modern nutritional diseases are just that. They haven't always been the ugly part of our life. They were introduced when people had to get their food from grocery stores, when people traded their whole foods from the family farm for those manufactured by the food processing industry. "

    "Coronary Heart Disease Mortality and Blood Cholesterol

    In the Seven Countries study, there were great differences in coronary heart disease (CHD) mortality at similar blood cholesterol levels.

    In this study Dr. Keys pointed to a correlation between deaths from coronary heart disease and serum cholesterol in 15 populations in seven countries.

    Dr Ravnskov plotted his original data which was not available in the research summaries. Particularly interesting were differences between two localities within the same country or nearby islands in each of 4 of the seven countries.

    West Finland had about 45 CHD (coronary heart disease) deaths at a median cholesterol level of 250 mg/dl. However North Karelia, also in Finland, had over 200 CHD deaths at about 260 mg/dl.

    The island of Crete had only 20 CHD deaths at cholesterol levels of about 200. The nearby island of Corfu had about 85 CHD deaths at a cholesterol level of about 190 mg/dl."

Hyperlipid: Professor John Yudkin and Dr Ancel Keys - 1 views

  •  
    "Here's a page or so (p163-4) from John Yudkin's book "Pure White and Deadly", 1972 edition. Yudkin begins the chapter with an apology for talking about such uncomfortable disagreements in public. But he liked the truth.

    This quote covers opinion from Prof John Yudkin and Dr Meyer Friedman. You can hear their dislike of Keys. Keys was the architect of what has become the current world obesity epidemic and never one to let the truth get in the way of a good idea, as with his six nations "fat causes heart disease" study. Unfortunately Meyer's list of those easily misled did not include gullible politicians who set food policy. Keys was a very successful politico, with intense conviction of his own correctness. Fine if he had been right, which he wasn't."

MELATONIN DEFICIENCY - 0 views

    "In recent years, melatonin has been heralded as everything from snake-oil to miracle cure-all. As is often the case, the truth seems to lie somewhere in between. But make no mistake about it, melatonin is not a vitamin or supplement; despite it's over-the-counter accessibility, it is a hormone in the same category as estrogen, testosterone and thyroid hormone. Hormones, as a whole, are some of the most powerful regulatory chemicals functioning within the body. Therefore, hormone-containing supplements and medications should always be used judiciously, never indiscriminately or haphazardly. "

Ginkgo Biloba Doesn't Slow Mental Decline - 0 views

    "Dec. 29, 2009 - The hot-selling herbal supplement ginkgo biloba doesn't slow age-related mental decline, a six-year clinical study shows.

    The study has already shown that ginkgo does not prevent dementia or Alzheimer's disease in the elderly.

    Now study leader Steven T. DeKosky, MD, and colleagues have sifted through the data to look for some sign that ginkgo might slow mental decline in healthy, aging individuals -- or, perhaps, in those already showing the first signs of cognitive impairment.

    No such sign was found.

    "Compared with placebo, the use of Ginkgo biloba, 120 mg twice daily, did not result in less cognitive decline in older adults with normal cognition or with mild cognitive impairment," the researchers conclude."

Drug from mushroom may help treat cancer - UPI.com - 0 views

  •  
    "NOTTINGHAM, England, Dec. 29 (UPI) -- A drug derived from a mushroom -- cordycepin -- may be used to treat some cancers, British researchers say.

    Dr. Cornelia de Moor of The University of Nottingham in England and colleagues are investigating the drug originally extracted from a rare parasitic mushroom called cordyceps that grows on caterpillars.

    The researchers say low-dose cordycepin seems to inhibit the uncontrolled growth and division of cells and at high doses it also inhibits growth by stopping cells from sticking together. Both of these effects, they say, probably have the same underlying mechanism -- interfering with the production of cell proteins.

    For the last decade, the focus of nutritional advice for prevention of chronic disease has been to limit or reduce
    total fat intake and to consume large amounts of carbohydrate. However, this advice is inconsistent with many
    lines of evidence indicating that unsaturated fats have beneficial metabolic effects and reduce risk of coronary
    heart disease. More recent evidence has also shown that the large majority of carbohydrates in Western diets,
    consisting of refined starches and sugars, have adverse metabolic effects and increase risks of coronary heart
    disease and type 2 diabetes. Unfortunately, a major opportunity for health improvement has been lost by failing
    to distinguish healthy from unhealthy forms of carbohydrates and fats. Recent analyses indicate that moderate
    changes in diet, together with regular physical activity and not smoking, can prevent the large majority of heart
    disease, type 2 diabetes, and some forms of cancer. These findings have substantial relevance for many populations
    in Asia, where incidence of type 2 diabetes is rising rapidly.

    Anticancer Res. 2009 Nov;29(11):4353-60.
    PMID: 20032378

    The effects of life-long dietary exposure, starting in utero, to high retinol, low vitamin D, or high retinol in combination with low vitamin D on intestinal tumorigenesis in Min/+ mice were investigated. In males, high retinol alone significantly increased the number (2.6-fold) and size (1.3-fold) of small intestinal tumours; in females no significant increase in tumour number or size was seen. In both genders, low vitamin D intake alone did not affect intestinal tumorigenesis. In males, intake of the combined high retinol/low vitamin D diet did not further increase the effects caused by high retinol alone. In females, however, the high retinol/low vitamin D-induced increase in tumour number (3.1-fold) and tumour size (1.5-fold) exceeded that of high retinol alone. In conclusion, a high dietary intake of retinol stimulated intestinal tumorigenesis in Min/+ mice. Furthermore, the results indicate a combined effect of high retinol and low vitamin D on tumorigenesis in females"

    Eicosanoids and Ischemic Heart Disease, Part II
    Here's where it gets more complicated and more interesting. The ratio of omega-6 to omega-3 matters, but so does the total amount of each. This is a graph from a 1992 paper by Dr. Lands:

    In sum, this suggests that the single best way to avoid a heart attack is to reduce omega-6 consumption and ensure an adequate source of omega-3. The lower the omega-6, the less the omega-3 matters. This is a nice theory, but where's the direct evidence? In the next post, I'll discuss the controlled trial that proved this concept once and for all: the Lyon diet-heart trial.

    Anticancer activities of various extracts of the medicinal mushroom, Ganoderma lucidum, have been widely demonstrated and are mainly associated with the presence of different bioactive polysaccharides and triterpenoids. We have evaluated and compared in vitro and in vivo the antitumor effects of two preparations from Ganoderma lucidum: a methanol extract containing total terpenoids (GLme) and a purified methanol extract containing mainly acidic terpenoids (GLpme). Both extracts inhibited tumor growth of B16 mouse melanoma cells inoculated subcutaneously into syngeneic C57BL/6 mice and reduced viability of B16 cells in vitro, whereby GLme exhibited stronger effect. Furthermore, anticancer activity of GLme was demonstrated for the first time against two other rodent tumor cell lines, L929-mouse fibrosarcoma and C6-rat astrocytoma. The mechanism of antitumor activity of GLme comprised inhibition of cell proliferation and induction of caspase-dependent apoptotic cell death mediated by upregulated p53 and inhibited Bcl-2 expression. Moreover, the antitumor effect of the GLme was associated with intensified production of reactive oxygen species, whereas their neutralization by the antioxidant, N-acetyl cysteine, resulted in partial recovery of cell viability. Thus, our results suggest that GLme might be a good candidate for treatment of diverse forms of cancers.

Lingzhi mushroom - Wikipedia, the free encyclopedia - 0 views

  •  
    "Língzhī (traditional Chinese: 靈芝; simplified Chinese: 灵芝; Japanese: reishi; Korean: yeongji, hangul: 영지) is the name for one form of the mushroom Ganoderma lucidum, and its close relative Ganoderma tsugae. Ganoderma lucidum enjoys special veneration in Asia, where it has been used as a medicinal mushroom in traditional Chinese medicine for more than 4,000 years, making it one of the oldest mushrooms known to have been used in medicine.

    Lingzhi may possess anti-tumor, immunomodulatory and immunotherapeutic activities, supported by studies on polysaccharides, terpenes, and other bioactive compounds isolated from fruiting bodies and mycelia of this fungus (reviewed by R. R. Paterson[4] and Lindequist et al.[7]). It has also been found to inhibit platelet aggregation, and to lower blood pressure (via inhibition of angiotensin-converting enzyme[8]), cholesterol and blood sugar.[9]

    Laboratory studies have shown anti-neoplastic effects of fungal extracts or isolated compounds against some types of cancer. In an animal model, Ganoderma has been reported to prevent cancer metastasis,[10] with potency comparable to Lentinan from Shiitake mushrooms.[11]

    The mechanisms by which G. lucidum may affect cancer are unknown and they may target different stages of cancer development: inhibition of angiogenesis (formation of new, tumor-induced blood vessels, created to supply nutrients to the tumor) mediated by cytokines, cytoxicity, inhibiting migration of the cancer cells and metastasis, and inducing and enhancing apoptosis of tumor cells

    Glucose restriction can extend normal cell lifespan and impair precancerous cell growth through epigenetic control of hTERT and p16 expression.
    Li Y, Liu L, Tollefsbol TO.
    FASEB J. 2009 Dec 17. [Epub ahead of print]
    PMID: 20019239
    doi: 10.1096/fj.09-149328

    Cancer cells metabolize glucose at elevated rates and have a higher sensitivity to glucose reduction. However, the precise molecular mechanisms leading to different responses to glucose restriction between normal and cancer cells are not fully understood. We analyzed normal WI-38 and immortalized WI-38/S fetal lung fibroblasts and found that glucose restriction resulted in growth inhibition and apoptosis in WI-38/S cells, whereas it induced lifespan extension in WI-38 cells. Moreover, in WI-38/S cells glucose restriction decreased expression of hTERT (human telomerase reverse transcriptase) and increased expression of p16(INK4a). Opposite effects were found in the gene expression of hTERT and p16 in WI-38 cells in response to glucose restriction. The altered gene expression was partly due to glucose restriction-induced DNA methylation changes and chromatin remodeling of the hTERT and p16 promoters in normal and immortalized WI-38 cells. Furthermore, glucose restriction resulted in altered hTERT and p16 expression in response to epigenetic regulators in WI-38 rather than WI-38/S cells, suggesting that energy stress-induced differential epigenetic regulation may lead to different cellular fates in normal and precancerous cells. Collectively, these results provide new insights into the epigenetic mechanisms of a nutrient control strategy that may contribute to cancer therapy as well as antiaging approaches.

Calorie restriction: Scientists take important step toward 'fountain of youth' - 0 views

  •  
    "ScienceDaily (Dec. 26, 2009) - Going back for a second dessert after your holiday meal might not be the best strategy for living a long, cancer-free life say researchers from the University of Alabama at Birmingham. That's because they've shown exactly how restricted calorie diets -- specifically in the form of restricted glucose -- help human cells live longer.


    They found that the normal cells lived longer, and many of the precancerous cells died, when given less glucose. Gene activity was also measured under these same conditions. The reduced glucose caused normal cells to have a higher activity of the gene that dictates the level of telomerase, an enzyme that extends their lifespan and lower activity of a gene (p16) that slows their growth. Epigenetic effects (effects not due to gene mutations) were found to be a major cause in changing the activity of these genes as they reacted to decreased glucose levels.

    "Western science is on the cusp of developing a pharmaceutical fountain of youth" said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "This study confirms that we are on the path to persuading human cells to let us to live longer, and perhaps cancer-free, lives.""

    "NEW YORK (Reuters Health) - Want to keep your eyesight sharp as you age? Eating lots of fish packed with healthy omega-3 fatty acids could help, new research suggests.

    Among 1,837 people who had early signs of age-related macular degeneration (AMD), those with the highest consumption of omega-3 fatty acids were 30 percent less likely to progress to the advanced form of the disease over a 12-year period than those with the lowest omega-3 intake, researchers found."
