Key feature of immune system survived in humans, other primates for 60 million years
A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans - but no other known animal species. view more (2009-08-19)
Scientists question folic acid fortification
Scientists at the Institute of Food Research have highlighted possible consequences of fortifying flour with folic acid due to new evidence of how it is absorbed by the body. view more (2007-11-05)
Levels of folate in men's diets is linked to chromosomal abnormalities in their sperm
Researchers have found an association between a vitamin found in leafy green vegetables, fruit and pulses and levels of chromosomal abnormalities in men's sperm. Men who consumed high levels of folate (a water-soluble B vitamin that occurs naturally in food) and folic acid (the synthetic form of the vitamin) tended to have lower levels of abnormal... view more...

MIT biologists solve vitamin puzzle
Solving a mystery that has puzzled scientists for decades, MIT and Harvard researchers have discovered the final piece of the synthesis pathway of vitamin B12—the only vitamin synthesized exclusively by microorganisms. view more (2007-03-23)
Vitamin C injections slow tumor growth in mice
High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers, researchers from the National Institutes of Health (NIH) report in the August 5, 2008, issue of the Proceedings of the National Academy of Sciences. view more (2008-08-05)
Mutant rats offer clues to medical mystery
A research project at Rice University has brought scientists to the brink of comprehending a long-standing medical mystery that may link cardiovascular disease, osteoporosis and perhaps even Alzheimer's disease. view more (2009-02-18)
New research clarifies roles of calcium, vitamin D, and protein in bone health, fracture risk
New research shows calcium in food might do more to protect bones than supplemental calcium in pill form, according to results presented at the IOF World Congress on Osteoporosis in Toronto, Canada. Bones lose calcium as they age, making them vulnerable to osteoporosis and fractures. view more (2006-06-06)
Study suggests a little milk could go a long way for your heart
Grabbing as little as one glass of lowfat or fat free milk could help protect your heart, according to a new study published in the American Journal of Clinical Nutrition. Researchers found that adults who had at least one serving of lowfat milk or milk products each day had 37 percent lower odds of poor kidney function linked to heart disease... view more...

Vitamin A signals offer clues to treating autoimmunity
Distributed around the body, dendritic cells act as the security alarms of the immune system. After sensing the presence of intruders, dendritic cells can transmit the alarm to white blood cells or tell them to relax, depending on the signals they send out. view more (2009-03-02)
Dietary modifications may not benefit cancer patients
One study, a meta-analysis of 59 trials, found little evidence that diet is associated with survival or prognosis. The other study suggests that neither use of garlic nor vitamin supplements delays the progression of precancerous gastric lesions to cancer. view more (2006-07-19)
Newly Identified Mechanism Helps Explain Why People of African Descent Are More Vulnerable to Tuberculosis
A team of scientists has identified a cellular mechanism that may help explain the puzzle of why people of African descent are more susceptible to tuberculosis infection and why, once infected, they develop more severe states of the disease than whites. view more (2006-02-27)
Blood test identifies women at risk from Alzheimer's
Middle-aged women with high levels of a specific amino acid in their blood are twice as likely to suffer from Alzheimer's many years later, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden. view more (2009-11-09)
Antioxidant users don't live longer, analysis of studies concludes
The vitamin industry has long touted antioxidants as a way to improve health by filling in gaps in diet, but a new review of studies found no evidence that the nutrition supplements extend life. view more (2008-04-16)
Folic Acid Can Prevent Heart Disease
Folic acid is not only a safeguard against spina bifida and other birth defects in babies - it can also prevent heart disease and strokes, two of Northern Ireland's biggest killers, according to research from the University of Ulster. Research at the University has shown and folic acid and three other related B-vitamins can prevent the... view more... (2002-09-18)
Super chow, laced with semi-synthetic vitamin E derivative, inhibited spread of cancer in mice
A chemically altered form of vitamin E mixed into mouse chow dramatically reduced spread of aggressive mammary cancer in mice, suggesting that the compound in pill form could be used to treat human metastatic cancer, according to a report in the October 1 issue of the journal Cancer Research. view more (2006-10-03)
Antioxidants may slow vision loss
Scientists at Johns Hopkins have successfully blocked the advance of retinal degeneration in mice with a form of retinitis pigmentosa (RP) by treating them with vitamin E, alpha-lipoic acid and other antioxidant chemicals. view more (2006-07-20)
Depression may increase Alzheimer's risk in people with memory problems
People with memory problems who are depressed are more likely to develop Alzheimer's disease than those who aren't depressed, according to a new UCLA study. view more (2009-06-16)
Antioxidants show no clear benefit against cardiovascular events, death in high-risk women
Vitamins C and E and beta carotene, either individually or in combination, do not appear to reduce the risk of cardiovascular events or death among women at high risk for heart disease. view more (2007-08-14)
Low levels of vitamin B12 may increase risk for neural tube defects
Children born to women who have low blood levels of vitamin B12 shortly before and after conception may have an increased risk of a neural tube defect, according to an analysis by researchers at the National Institutes of Health, Trinity College Dublin, and the Health Research Board of Ireland. view more (2009-03-02)
Fatty fish consumption associated with lower risk of kidney cancer in women
