Higher Urinary Levels Of Commonly Used Plastic Compound, BPA, Linked To Cardiovascular Disease, Diabetes - Science Daily, 9/16/08 - "Higher levels of urinary Bisphenol A (BPA), a chemical compound commonly used in plastic packaging for food and beverages, is associated with cardiovascular disease, type 2 diabetes and liver-enzyme abnormalities ... Widespread and continuous exposure to BPA, primarily through food but also through drinking water, dental sealants, dermal exposure, and inhalation of household dusts, is evident from the presence of detectable levels of BPA in more than 90 percent of the U.S. population ... participants in the highest BPA concentration quartile had nearly three times the odds of cardiovascular disease compared with those in the lowest quartile. Similarly, those in the highest BPA concentration quartile had 2.4 times the odds of diabetes compared with those in the lowest quartile ... higher BPA concentrations were associated with clinically abnormal concentrations for three liver enzymes"

Clean living 'slows cell ageing' - BBC News, 9/15/08 - "Among 24 men asked to adopt healthy lifestyle changes for a US study in The Lancet Oncology, levels of telomerase increased by 29% on average ... Telomerase repairs and lengthens telomeres, which cap and protect the ends of chromosomes housing DNA ... These consisted of a diet high in fruit and vegetables, supplements of vitamins and fish oils, an exercise regimen and classes in stress management, relaxation techniques and breathing exercises"

Vitamin C Intake May Reduce Fracture Risk - Medscape, 9/15/08 - "Basically, people who had higher levels of vitamin C intake had half the rate of hip fractures as people who had the lowest vitamin C [levels]"

Psychological Distress May Increase Risk of Breast Cancer - Medscape, 9/15/08 - "The team evaluated interactions between breast cancer and severe life events -- such as loss of a parent or divorce of parents before age 20, or loss of a close relative or spouse -- and mild to moderate life events -- e.g., separation from a spouse, loss of a job, an economic crisis, or severe illness in a close relative ... Multivariate analysis revealed a positive association (odds ratio, 1.62) between exposure to more than one adverse life event and breast cancer. "It wasn't enough to be exposed to one life event, a woman had to be exposed to more than one event,""

Chemo Nausea Patch Approved - WebMD, 9/15/08 - "The FDA has approved Sancuso, a five-day patch that fights nausea from cancer chemotherapy"

8 natural pain relievers - MSNBC, 9/14/08 - "Capsaicin: For arthritis, shingles, or neuropathy ... InflaThera or Zyflamend: For arthritis ... Aquamin: For osteoarthritis ... SAM-e (S adenosylmethionine): For osteoarthritis ... Fish oil: For joint pain from arthritis or autoimmune disorders ... Methylsulfonyl-methane (MSM): For osteoarthritis"

Flaxseed Oil Pills vs. Fish Oil Pills - WebMD, 9/12/08 - "As expected, blood levels of EPA and DHA rose in the fish oil group, and ALA rose in the flaxseed oil group. EPA levels also rose in the flaxseed oil group, but only at the higher doses (2.4 to 3.6 grams per day). The researchers write that it's "quite attainable" to get that much ALA from foods without taking supplements ... Since flaxseed oil doesn't contain EPA, the firefighters' bodies must have converted some of the ALA into EPA. That didn't seem to happen at the lower doses of flaxseed oil ... DHA was a different story. The flaxseed oil group didn't get any increase in DHA levels; DHA only rose in the fish oil group"

COPD? Eat Your Veggies - Science Daily, 9/12/08 - "Sulforapane has been shown to be able to restore antioxidant gene expression in human epithelial tissue in which DJ-1 has been reduced. Isothicyanate compounds such as that found in broccoli inhibit KEAP1, and thus prevent it from degrading NRF2"

Accolades for Mediterranean Diet - WebMD, 9/11/08 - "people who followed a strict Mediterranean diet were: ... 9% less likely to die from heart disease or other cardiovascular problems ... 6% less likely to develop cancer or die from it ... 13% less likely to have Parkinson's or Alzheimer's disease"

Untapped Potential Of Antidepressants For Cancer - Science Daily, 9/11/08 - "Antidepressants work by affecting levels of chemicals known as prostaglandins. These are ephemeral, infinitesimal signallers self-regulating every cell in the body, including those serving mood and immunity ... Prostaglandins are responsible, paradoxically, for both cell function and dysfunction. Excessive prostaglandin synthesis depresses immune function and may induce cancer ... An ideal anticancer agent would inhibit prostaglandins in such a manner as to shut down the pathogenesis of cancer. The article indicates that antidepressants have such properties"

Can Fruits, Vegetables Cut Colon Cancer Risk? - WebMD, 9/11/08 - "Based on those answers, the researchers concluded that men who ate the most fruits and vegetables were 26% less likely to develop colorectal cancer than men who ate the least ... No decrease in risk associated with fruit and vegetable consumption was seen for women"

Cortisol And Fatty Liver: Researchers Find Cause Of Severe Metabolic Disorders - Science Daily, 9/11/08 - "The researchers in Herzig's team specifically switched off the cortisol receptor in the livers of mice, thus blocking the hormone's effect. As a result, the triglyceride level in the livers of the experimental animals dropped considerably"

Statins Lower Risk of Recurrent Stroke in Both Elderly, Younger Patients - Doctor's Guide, 9/10/08 - "Within each group, about half of the people received atorvastatin and about half received a placebo. The participants were then followed for an average of 4.5 years ... Low-density lipoprotein (LDL) cholesterol was lowered by an average of 61 points during the study for the elderly group, and by 59 points for the younger group. Those in the younger group reduced their risk for another stroke by 26% and the elderly group reduced their risk by 10%"

Bleeding Gums Linked To Heart Disease - Science Daily, 9/10/08 - "People with poor dental hygiene and those who don't brush their teeth regularly end up with bleeding gums, which provide an entry to the bloodstream for up to 700 different types of bacteria found in our mouths. This increases the risk of having a heart attack"

Eating Fish While Pregnant, Longer Breastfeeding Lead to Better Infant Development - Doctor's Guide, 9/10/08 - "Both higher fish consumption and longer breastfeeding are linked to better physical and cognitive development in infants" - See Mega Twin EPA at Amazon.com.

As Head And Neck Cancer Risks Evolve, More Treatment Options Emerge - Science Daily, 9/10/08 - "a compound from green tea enhances the effects of a FDA-approved drug (erlotinib) against head and neck cancer cells in animals, suggesting that it could work similarly in humans. The results are published in the September issue of International Journal of Cancer ... More than two-thirds of patients come to doctors with locally and regionally advanced disease, and their prognoses are dismal ... But head and neck cancers are potentially curable when diagnosed at an early stage" - Note:  I took about 8 capsules of green tea extract per day when I had my neck cancer.  Maybe that's one of the things that save me.

Vitamin K2 linked to better heart health - NutraUSA, 9/10/08 - "When the intakes of K1 and K2 were divided into four groups from the lowest to highest, no association was found between K1 intakes and calcification. However, high consumption of K2 (about 45 micrograms per day) was associated with 20 per cent decreased coronary calcification, compared with low consumption of K2 (about 18micrograms per day)" - See Vitamin K products at iHerb.  Related study:

  • Vitamin K may reverse arterial calcification - Nutra USA, 4/3/07 - "using 10-week old male Wistar Kyoto rats ... high-vitamin K intake (both K1 and K2) not only blocked the progress of further calcium accumulation but also lead to a greater than 37 per cent reduction of previously accumulated arterial calcium precipitates within six weeks"

Type 2 Diabetes: Control Blood Sugar, Blood Pressure - WebMD, 9/10/08 - "If you've got type 2 diabetes, the sooner you get intense about reining in your blood sugar, the better. It also pays to buckle down on your blood pressure and stay that way"

Is Probiotic Yakult Helpful In The Treatment Of Irritable Bowel Syndrome? - Science Daily, 9/10/08 - "A pilot study was undertaken to determine the effect of L. strain Shirota (Yakult®) on intestinal fermentation patterns of IBS patients. After 6 week of treatment with 1 x 65 mL dose of Yakult(R) daily, 9 of 14 patients (64%) completing the study had reversal of ERBHAL, with the median time of first rise increasing from 45 to 75 min (P = 0.03). Furthermore, symptoms improved in those in whom ERBHAL was corrected"

Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

The Dark Side of Testosterone Deficiency: II. Type 2 Diabetes & Insulin Resistance - J Androl. 2008 Sep 4 - "Low testosterone precedes elevated fasting insulin, glucose, and hemoglobin A1c (HbA1C) values and may even predict the onset of diabetes. Treatment of prostate cancer patients with surgical or medical castration exacerbates IR and glycemic control, strengthening the link between testosterone deficiency and onset of type-2 diabetes and IR. Androgen therapy of hypogonadal men improves insulin sensitivity, fasting glucose and Hemoglobin A1c levels. We suggest that androgen deficiency is associated with IR, T2D and MetS, and increased visceral fat deposition, which serves as an endocrine organ, producing inflammatory cytokines thus promoting endothelial dysfunction and vascular disease"

Fish, omega-3 Polyunsaturated Fatty Acids, and Mortality From Cardiovascular Diseases in a Nationwide Community-Based Cohort of Japanese Men and Women The JACC (Japan Collaborative Cohort Study for Evaluation of Cancer Risk) Study - J Am Coll Cardiol. 2008 Sep 16;52(12):988-996 - "For mortality from total cardiovascular disease, intakes of fish and omega-3 PUFA were associated with 18% to 19% lower risk ... We found an inverse association between fish and omega-3 PUFA dietary intakes and cardiovascular mortality, especially for heart failure, suggesting a protective effect of fish intake on cardiovascular diseases" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Vitamin B12 status and rate of brain volume loss in community-dwelling elderly - Neurology. 2008 Sep 9;71(11):826-32 - "Linear regression analysis showed that associations with vitamin B(12) and holoTC remained significant after adjustment for age, sex, creatinine, education, initial brain volume, cognitive test scores, systolic blood pressure, ApoE epsilon4 status, tHcy, and folate. Using the upper (for the vitamins) or lower tertile (for the metabolites) as reference in logistic regression analysis and adjusting for the above covariates, vitamin B(12) in the bottom tertile (<308 pmol/L) was associated with increased rate of brain volume loss (odds ratio 6.17 ... Low vitamin B(12) status should be further investigated as a modifiable cause of brain atrophy and of likely subsequent cognitive impairment in the elderly" - See vitamin B12 at Amazon.com.

Low plasma eicosapentaenoic acid and depressive symptomatology are independent predictors of dementia risk - Am J Clin Nutr. 2008 Sep;88(3):714-21 - "A high plasma EPA concentration may decrease the risk of dementia, whereas high ratios of n-6 to n-3 fatty acids and of AA to DHA may increase the risk of dementia, especially in depressed older persons. The role of EPA in dementia warrants further research" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Neat Tech Stuff :

  • In my 9/3/08 newsletter I talked about converting DVD to TiVo.  I ran into a minor snag with that.  With DVD concerts, sometimes the audio is in the .ac3 format.  If that happens, in DVD2AVPI you need to select "Audio - Output Method - Demux All Track" then convert the .ac3 file to a .wav file using something like PX3 AC3 to WAV.  Also the Western Digital WDG1S5000VN 500GB My DVR Expander eSATA is $150 delivered at Amazon.com.  TiVo wants $199 plus tax and shipping.
