Researchers link calorie intake to cell lifespan, cancer development (w/ Video)
"Researchers from the University of Alabama at Birmingham (UAB) have discovered that restricting consumption of glucose, the most common dietary sugar, can extend the life of healthy human-lung cells and speed the death of precancerous human-lung cells, reducing cancer's spread and growth rate.
The research has wide-ranging potential in age-related science, including ways in which calorie-intake restriction can benefit longevity and help prevent diseases like cancer that have been linked to aging, said principal investigator Trygve Tollefsbol, Ph.D., D.O., a professor in the Department of Biology.
"These results further verify the potential health benefits of controlling calorie intake." Tollefsbol said. "Our research indicates that calorie reduction extends the lifespan of healthy human cells and aids the body's natural ability to kill off cancer-forming cells.
DHA revisions offer hope to health claim rejections
"The affirmation that the omega-3 DHA can benefit cognitive and eye health offers hope to previously rejected claims. And it's business as usual regarding the overall health claims process, despite ratification of the Lisbon Treaty, said a European Commission representative.
At the NutraIngredients Health Claims 2010 conference in Brussels, the EC's Lars Korsholm explained the regulatory state-of-play for DHA claims.
“I think it will offer some hope to previously rejected claims in the sense that these claims that are now subject for discussion are generic in the sense that if other food business operators than those who actually submitted the application can claim to fulfill the conditions of use then they are equally entitled to use the claim,” explains Korsholm.
The statements come in relation to an October decision whereby the European Food Safety Authority (EFSA) affirmed that the omega-3 fatty acids, DHA and ALA, can benefit eye and cognitive development in babies.
Responding to the public comment period for Merck Selbstmedikation GmbH’s article 14 cognitive development claim that was rejected in March, EFSA affirmed its original stance that there was no need for additional supplementation of DHA (docosahexaenoic acid) and ALA (alpha-linolenic acid) because it already existed at adequate levels in the diet.
It supported their role in foetal and newborn eye and brain development but said there was an adequate supply in breast milk. "
Calorie intake linked to cell lifespan, cancer development

Conclusion: Vitamin D supplementation during the first year of life is associated with a reduced risk of schizophrenia in males. Preventing hypovitaminosis D during early life may reduce the incidence of schizophrenia.

Developmental toxicity evaluation of berberine in rats and mice.

BACKGROUND: Berberine, a plant alkaloid, is found in some herbal teas and health-related products. It is a component of goldenseal, an herbal supplement. Berberine chloride dihydrate (BCD) was evaluated for developmental toxicity in rats and mice.
METHODS: Berberine chloride dihydrate was administered in the feed to timed-mated Sprague-Dawley (CD) rats (0, 3625, 7250, or 14,500 ppm; on gestational days [GD] 6-20), and Swiss Albino (CD-1) mice (0, 3500, 5250, or 7000 ppm; on GD 6-17). Ingested doses were 0, 282, 531, and 1313 mg/kg/day (rats) and 0, 569, 841, and 1155 mg/kg/day (mice).
RESULTS:There were no maternal deaths. The rat maternal lowest observed adverse effect level (LOAEL), based on reduced maternal weight gain, was 7250 ppm. The rat developmental toxicity LOAEL, based on reduced fetal body weight per litter, was 14,500 ppm. In the mouse study, equivocal maternal and developmental toxicity LOAELs were 5250 ppm. Due to scattering of feed in the high dose groups, a gavage study at 1000 mg/kg/day was conducted in both species.
CONCLUSIONS: In rats, maternal, but not fetal adverse effects were noted. The maternal toxicity LOAEL remained at 7250 ppm (531 mg/kg/day) based on the feed study and the developmental toxicity NOAEL was raised to 1000 mg/kg/day BCD based on the gavage study. In the mouse, 33% of the treated females died. Surviving animals had increased relative water intake, and average fetal body weight per litter decreased 5-6% with no change in live litter size. The maternal toxicity LOAEL remained at 5250 ppm (841 mg/kg/day) BCD, based on increased water consumption. The developmental toxicity LOAEL was raised to 1000 mg/kg/day BCD based on decreased fetal body weight.

New Research by D*action Member Dr. Cedric Garland Suggests Role Low Levels of Vitamin D Play in Cancer Development
San Diego, CA (PRWEB) May 25, 2009 -- Coming on the heels of the publishing in the Annals of Epidemiology of a new study led by Dr. Cedric Garland, on the preventive measures of vitamin D, GrassrootsHealth D*action Project is calling on physicians, health clinics and groups throughout the country to recognize the need for determining vitamin D levels and to ensure the public have their blood levels of vitamin D tested.
According to research from the newly published study by Cedric F. Garland, Dr. P.H., FACE, Department of Family and Preventive Medicine and Moores Cancer Center of the University of California, San Diego (UCSD), "It is projected that raising the minimum year-around serum 25(OH)D level to 40-60 ng/ml (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three quarters of deaths from these diseases, in the US and Canada."
