Vitamin D Deficiency Is Widespread And On The Increase - Science Daily, 6/30/09 - "A new report issued by the International Osteoporosis Foundation (IOF) and published in the scientific journal Osteoporosis International1, shows that populations across the globe are suffering from the impact of low levels of vitamin D. The problem is widespread and on the increase, with potentially severe repercussions for overall health and fracture rates" - See vitamin D at Amazon.com.

Orange Juice Worse For Teeth Than Whitening Agents - Science Daily, 6/30/09 - "the effects of 6 percent hydrogen peroxide, the common ingredient in professional and over-the-counter whitening products, are insignificant compared to acidic fruit juices. Orange juice markedly decreased hardness and increased roughness of tooth enamel"

Metabolic Factors May Play A Role In Risk For Breast Cancer - Science Daily, 6/30/09 - "The metabolic syndrome is characterized by elevated insulin levels, and in recent years scientists have proposed that insulin may contribute directly or indirectly to the development of breast cancer ... women who had the metabolic syndrome during the three to five years prior to breast cancer diagnosis had roughly a doubling of risk ... Findings also showed significant associations with elevated blood glucose levels, triglycerides and diastolic blood pressure. For diastolic blood pressure, the result was stronger, with more than a two-fold increased risk (relative risk = 2.4). Generally, for both triglycerides and glucose the relative risk was about 1.7 for all breast cancer"

Patients With Moderate To Severe Periodontitis Need Evaluation For Heart Disease Risk - Science Daily, 6/30/09 - "Periodontitis is common, with mild to moderate forms affecting 30 to 50% of adults and the severe generalized form affecting 5 to 15% of all adults in the USA. In addition, there is now strong evidence that people with periodontitis are at increased risk of atherosclerotic CVD — the accumulation of lipid products within the arterial vascular wall"

Antioxidant may boost exercise endurance - msnbc.com, 6/29/09 - "Compared with days of no supplementation, the quercetin supplement periods were associated with a modest — nearly 4 percent — increase in maximum oxygen uptake. Quercetin was also associated with a 13 percent increase in "ride time" before the volunteers were too fatigued to continue" - See quercetin at Amazon.com.

Aerobic Activity May Keep The Brain Young - Science Daily, 6/29/09 - "The brain’s blood vessels naturally narrow and become more tortuous with advancing age, but the study showed the cerebrovascular patterns of active patients appeared “younger” than those of relatively inactive subjects. The brains of these less active patients had increased tortuosity produced by vessel elongation and wider expansion curves"

High Levels Of Cycling Training Damage Sperm: What Can Be Done To Protect Triathletes From Infertility? - Science Daily, 6/29/09 - "While all triathletes had less than 10% of normal-looking sperm, the men with less than 4% – at which percentage they would generally be considered to have significant fertility problems – were systematically covering over 300km per week on their bicycles"

Superfood Soy Linked To Reduction In Smoker's Lung Damage Risk - Science Daily, 6/28/09 - "Soy consumption was found to be positively correlated with lung function and inversely associated with the risk of COPD. It has been suggested that flavonoids from soy foods act as an anti-inflammatory agent in the lung, and can protect against tobacco carcinogens for smokers"

Omega-3 deficiency causes 96,000 US deaths per year, say researchers - Nutra USA, 6/26/09 - "this new study validates that Omega-3 EPA/DHA is more than just part of a healthy diet...it's a matter of life and death ...

Dietary Fat Linked To Pancreatic Cancer - Science Daily, 6/26/09 - "Participants who consumed high amounts of saturated fats had 36% higher relative rates of pancreatic cancer compared with those who consumed low amounts"

Study: Overweight People Live Longer - WebMD, 6/25/09 - "There is more evidence that people who are overweight tend to live longer than people who are underweight, normal weight, or obese ... Those classified as underweight were 73% more likely to die ... Those classified as extremely obese with BMI of 35 or greater were 36% more likely to die ... Those classified as obese with BMI 30-34.9 had about the same risk of death ... Those classified as overweight with BMI 25-29.9 were 17% less likely to die"

High Carbohydrate Foods Can Cause Heart Attacks - Science Daily, 6/25/09 - "Doctors have known for decades that foods like white bread and corn flakes aren't good for cardiac health ... foods with a high glycemic index distended brachial arteries for several hours ... Enormous peaks indicating arterial stress were found in the high glycemic index groups: the cornflakes and sugar group ... During the consumption of foods high in sugar, there appears to be a temporary and sudden dysfunction in the endothelial walls of the arteries ... Endothelial health can be traced back to almost every disorder and disease in the body. It is "the riskiest of the risk factors,""

Alcohol consumption as a risk factor for dementia and cognitive decline: meta-analysis of prospective studies - Am J Geriatr Psychiatry. 2009 Jul;17(7):542-55 - "Alzheimer disease (AD) ... vascular dementia (VaD) ... The pooled relative risks (RRs) of AD, VaD, and Any dementia for light to moderate drinkers compared with nondrinkers were 0.72 (95% CI = 0.61-0.86), 0.75 (95% CI = 0.57-0.98), and 0.74 (95% CI = 0.61-0.91), respectively. When the more generally classified "drinkers," were compared with "nondrinkers," they had a reduced risk of AD (RR = 0.66, 95% CI = 0.47-0.94) and Any dementia (RR = 0.53, 95% CI = 0.53-0.82) but not cognitive decline. There were not enough data to examine VaD risk among "drinkers." Those classified as heavy drinkers did not have an increased risk of Any dementia compared with nondrinkers, but this may reflect sampling bias. Our results suggest that alcohol drinkers in late life have reduced risk of dementia. It is unclear whether this reflects selection effects in cohort studies commencing in late life, a protective effect of alcohol consumption throughout adulthood, or a specific benefit of alcohol in late life"

Red Wine Protects against Ethanol-Induced Oxidative Stress in Rat Liver - J Agric Food Chem. 2009 Jun 23 - "Red wine (RW) is rich in polyphenolic antioxidants, often reported as hepatoprotective agents ... Six-month-old Wistar rats were treated with RW or EtOH; controls were pair-fed. EtOH increased 8-hydroxy-2'-deoxyguanosine and decreased reduced and oxidized glutathione. These animals also displayed stimulated superoxide dismutase, catalase, and glutathione reductase activities. RW treatment decreased malondialdehyde and reduced glutathione levels. Glutathione-S-transferase and selenium-dependent glutathione peroxidase activities were stimulated and glutathione reductase activity was inhibited by RW intake. No modifications were detected in nuclear factor-kappa B or alkaline phosphatase activities. EtOH consumption induced fibrosis in portal spaces and hepatocyte lipid accumulation that were absent with RW treatment. This paper highlights the importance of RW nonalcoholic components and the relevance of biological matrix in the study of EtOH oxidative effects"

Dietary lycopene and tomato extract supplementations inhibit nonalcoholic steatohepatitis-promoted hepatocarcinogenesis in rats - Int J Cancer. 2009 Jun 23 - "Epidemiological and experimental studies provide supportive evidence that lycopene (LY), a major carotenoid from tomatoes and tomato products, may act as a chemopreventive agent against certain types of cancers. We recently showed that high-fat diet (HFD)-induced nonalcoholic steatohepatitis (NASH) promoted diethylnitrosamine (DEN)-initiated hepatocarcinogenesis in a rat model ... tomato extract (TE) ... These data indicate that LY and TE can inhibit NASH-promoted hepatocarcinogenesis mainly as a result of reduced oxidative stress, which could be fulfilled through different mechanisms" - See Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com.

Folate intake and the risk of colorectal cancer in a Korean population - Eur J Clin Nutr. 2009 Jun 24 - "Cases were more frequently found to have a family history of CRC among first-degree relatives, to consume more alcohol, to be more likely current smokers and less likely to participate in vigorous physical activity than the controls. In the overall data for men and women combined, multivariate ORs (95% confidence interval (CI), P for trend) comparing the highest vs the lowest quartile of dietary folate intake were: 0.47 (0.32-0.69, < 0.001) for CRC, 0.42 (0.26-0.69, < 0.001) for colon cancer and 0.48 (0.28-0.81, 0.007) for rectal cancer. An inverse association was also found in women with dietary folate intake: 0.36 (0.20-0.64, < 0.001) for CRC, 0.34 (0.16-0.70, 0.001) for colon cancer and 0.30 (0.12-0.74, 0.026) for rectal cancer, but not in men. In addition, the total folate intake of women was strongly associated with a reduced risk of rectal cancer (OR, 0.38; 95% CI, 0.17-0.88; P for trend=0.04). ... We found a statistically significant relationship between higher dietary folate intake and reduced risk of CRC, colon cancer and rectal cancer in women. A significant association is indicated between higher total folate intake and reduced risk of rectal cancer in women"

• Efficacy of a Vitamin/Nutriceutical Formulation for Early-stage Alzheimer's Disease: A 1-Year, Open-Label Pilot Study With an 16-Month Caregiver Extension - Am J Alzheimers Dis Other Demen. 2008 Dec 1 - "We examined the efficacy of a vitamin/nutriceutical formulation (folate, vitamin B6, alpha-tocopherol, S-adenosyl methionine, N-acetyl cysteine, and acetyl-L-carnitine) in a 12-month, open-label trial with 14 community-dwelling individuals with early-stage Alzheimer's disease. Participants improved in the Dementia Rating Scale and Clock-drawing tests (Clox 1 and 2). Family caregivers reported improvement in multiple domains of the Neuropsychiatric Inventory (NPI) and maintenance of performance in the Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADL). Sustained performance was reported by caregivers for those participants who continued in an 16-month extension. Performance on the NPI was equivalent to published findings at 3 to 6 months for donepezil and exceeded that of galantamine and their historical placebos. Participants demonstrated superior performance for more than 12 months in NPI and ADL versus those receiving naproxen and rofecoxib or their placebo group. This formulation holds promise for treatment of early-stage Alzheimer's disease prior to and/or as a supplement for pharmacological approaches"
