(NaturalNews) 30 years ago the famous Nobel laureate Linus Pauling said that vitamin C supplements can prevent cancer, a highly controversial statement at the time. Now a team of Johns Hopkins scientists have shown that vitamin C stops the growth of some tumors in mice. The Study The study was lead by Chi Dang, M.D., Ph.D., professor of medicine and oncology and Johns Hopkins Family Professor in Oncology Research. Their work is detailed in Cancer Cell, Volume 12, Issue 3, 230-238, 11 September, 2007. They found that the antioxidants' actual role may be to destabilize a tumor's ability to grow under conditions where there isn't enough oxygen to feed it. The conventional belief is that vitamin C helps prevent cancer growth by grabbing up volatile oxygen free radical molecules and preventing the damage they do to our DNA. "The potential anticancer benefits of antioxidants have been the driving force for many clinical and preclinical studies," Says Dang. "By uncovering the mechanism behind antioxidants, we are now better suited to maximize their therapeutic use."

Feb 23, 2009 (CIDRAP News) - In a development that could create new tools to prevent and treat seasonal and pandemic influenza, researchers have identified and tested human monoclonal antibodies (mAbs) that can neutralize influenza A viruses, including lethal H5N1 avian influenza.\n\nThe findings raise hopes for a universal flu vaccine and shed light on new options for preventing and treating influenza infections, researchers from Dana-Farber Cancer Center, Burnham Institute for Medical Research, and the US Centers for Disease Control and Prevention (CDC) reported yesterday in an early online edition of Nature Structural and Molecular Biology. The study was supported by a grant from the National Institute of Allergy and Infectious Diseases (NIAID).

Feb. 20, 2009 (San Diego) -- High doses of B vitamins may help prevent stroke in high-risk people, new research suggests.\n\nThe finding comes from the Heart Outcomes Prevention Evaluation 2 trial of more than 5,500 men and women with heart disease. Participants were assigned to a daily regime

Authors of the study reported that carnitine deficiency is a risk factor and should be viewed as a mechanism in hepatic carcinogenesis, and that long-term L-carnitine supplementation prevents the development of liver cancer. Therefore, carnitine supplementation alone or in combination with other natural chemopreventive compounds could be used to prevent, slow or reverse the occurrence of liver cance

Prevention of nonvertebral fractures with oral vitamin D and dose dependency: a meta-analysis of randomized controlled trials. Bischoff-Ferrari HA, Willett WC, Wong JB, Stuck AE, Staehelin HB, Orav EJ, Thoma A, Kiel DP, Henschkowski J. Arch Intern Med. 2009 Mar 23;169(6):551-61. PMID: 19307517 Conclusion Nonvertebral fracture prevention with vitamin D is dose dependent, and a higher dose should reduce fractures by at least 20% for individuals aged 65 years or older.

ScienceDaily (May 22, 2009) - A new article in the journal Risk Analysis assessed various ways in which aerosol transmission of the flu, a central mode of diffusion which involves breathing droplets in the air, can be reduced. Results show that face protection is a key infection control measure for influenza and can thus affect how people should try to protect themselves from the swine flu. Lawrence M. Wein, Ph.D., and Michael P. Atkinson of Stanford University constructed a mathematical model of aerosol transmission of the flu to explore infection control measures in the home. Their model predicted that the use of face protection including N95 respirators (these fit tight around the face and are often worn by construction workers) and surgical masks (these fit looser around the face and are often worn by dental hygienists) are effective in preventing the flu. The filters in surgical masks keep out 98 percent of the virus. Also, only 30 percent of the benefits of the respirators and masks are achieved if they are used only after an infected person develops symptoms. "Our research aids in the understanding of the efficacy of infection control measures for influenza, and provides a framework about the routes of transmission," the authors conclude. This timely article has the potential to impact current efforts and recommendations to control the so-called swine flu by international, national and local governments in perspective. This study is published in the journal Risk Analysis.

There is new research out this morning from South Dakota State University which offers evidence that including flax in the diet may help prevent colorectal tumors or keep tumors from growing as quickly when they do form. Professor C. Dwivedi, head of SDSU's Department of Pharmaceutical Sciences, directed the study. The study was conducted in mice that develop spontaneous intestinal tumors. This strain of mouse is often used as a model by cancer researchers due to this mutation.

(SACRAMENTO, Calif.) - Osteoporosis affects many women and can cause painful, disabling and even life-threatening fractures. Researchers from the UC Davis Department of Internal Medicine are seeking a simple, inexpensive way to prevent the disease. Strontium citrate is a widely available, over-the-counter dietary supplement promoted to "improve bone health." Strontium is a natural element found in bone in all people. Strontium citrate is another form of strontium ranelate, a proven medication prescribed across Europe and Australia to treat and prevent osteoporosis and related fractures. Unlike pharmaceuticals, strontium citrate is not a prescribed medication and is inexpensive.

European experts in cancer and nutrition are meeting in Zurich, Switzerland late this month to discuss cutting-edge research in one of the most important and fiercely debated topics in cancer prevention: the link between diet and cancer. There is growing evidence that many cancers may be prevented through healthy lifestyle, including a nutritionally balanced diet. In addition, nutritional problems can also have a negative impact on cancer management and the lives of patients. Other presentations will include new data on topics such as: Childhood nutrition and later breast cancer risk The anti-tumour effects of green tea Malnutrition and patient distress in cancer Possible anti-tumour effects of soy extracts in mice Estrogens in beef and cancer risk

Pomegranate juice is remarkably rich in antioxidants, such as soluble polyphenols, tannins, and anthocyanins, which scavenge free radicals and help prevent DNA damage that can lead to a number of serious health conditions. It is also believed to have antiatherosclerotic properties, as studies in Israel have shown that the fruit juice, taken daily, prevented the thickening of arteries and slowed down cholesterol oxidation by almost half (Clin Nutr. 2004 Jun;23(3):423-33).

ScienceDaily (May 12, 2009) - Taking folic acid supplements for at least a year before conception is associated with reduction in the risk of premature birth, according to a study by Radek Bukowski (from the University of Texas Medical Branch, United States of America) and colleagues. Although most pregnancies last about 40 weeks, many babies (for example around 12% in the United States) are born before 37 completed weeks of pregnancy. Babies born prematurely are less likely to survive than full-term babies and are more likely to have breathing difficulties and learning or developmental disabilities. Currently, there are no effective methods of prevention or treatment of premature (preterm) birth, but previous studies have suggested that lower concentrations of folate (folic acid) are associated with shorter duration of pregnancy. Bukowski and colleagues therefore tested this idea, by analyzing data collected from a cohort of nearly 35,000 pregnant women. The results of this study showed that taking folate supplements for at least one year before conception was associated with a 70% reduction in spontaneous premature birth between 20 and 28 weeks (a reduction from 0.27% to 0.04%), and a 50% reduction between 28 and 32 weeks (reduction from 0.38% to 0.18%), as compared to the rate of preterm birth when mothers did not take additional folate supplementation. Folate supplementation for less than a year before conception was not linked to a reduction in the risk of premature birth in this study, and folate supplementation was not associated with any other complications of pregnancy. In a related commentary also published in this week's PLoS Medicine, Nicholas Fisk from the University of Brisbane, Australia, and colleagues (who were not involved in the original study) say "Methodologically, the study has several strengths... It is based on a huge dataset, with prospective recording of dietary supplements and potential confounders, and gestational age determined accu
