Recent Longevity News for the seven days ending 9/5/07.  You should consult your doctor if you are taking any medications.

Study links low-GI kids' breakfast to less calories - Nutra USA, 9/4/07 - "The children ate on average 61 kcal less over the days they were given the low-GI breakfast, compared with the days when they ate a high-GI breakfast"

Avocados May Help Prevent Oral Cancer, Study Shows - Science Daily, 9/4/07 - "Nutrients taken from avocados are able to thwart oral cancer cells, killing some and preventing pre-cancerous cells from developing into actual cancers"

More vitamin D could mean fewer cancers: study - Reuters, 9/4/07 - "They argue that, based on their data, if Americans were able to maintain a vitamin D level of at least 55 ng/mL, 60,000 cases of colon cancer and 85,000 cases of breast cancer could be prevented every year. Worldwide, those figures could be 250,000 and 350,000, respectively ... Garland and his colleagues recommend that, in addition to modest sun exposure, adults get 2,000 IU of vitamin D per day -- which is the "tolerable upper intake level" set by U.S. health officials"

Fat Transforms Vitamin C From 'Good Cop' Into 'Bad Cop' - Science Daily, 9/4/07 - "Nitrites, which are present in human saliva, and in certain preserved foodstuffs, may be converted to cancer causing compounds called nitrosamines. Nitrosamines are formed in acidic conditions, such as those afforded by stomach acid, but vitamin C inhibits their formation, by converting nitrite to nitric oxide ... Without fat, vitamin C curbed the levels of two nitrosamines by a factor of between five and 1000. And it completely eliminated the production of the other two ... But when 10% fat was added, vitamin C actually boosted the production of nitrosamines between 8 and 140-fold"

Red Wine Compound Shown To Prevent Prostate Cancer - Science Daily, 8/31/07 - "n the study resveratrol-fed mice showed an 87 percent reduction in their risk of developing prostate tumors that contained the worst kind of cancer-staging diagnosis ... Other mice in the study, those fed resveratrol but still developed a less-serious form of prostate cancer, were 48 percent more likely to have their tumor growth halted or slowed when compared to mice who did not consume the compound ... A cancer prevention researcher lives for these days when they can make that kind of finding" - See resveratrol products at Amazon.com.

Heavy Drinking Raises Blood Pressure In Older Men Regardless Of 'Good' Cholesterol - WebMD, 8/31/07 - "When looking at men of all ages, those with the lowest level of good cholesterol had the highest blood pressure in all three groups: nondrinkers, moderate drinkers and heavy drinkers. However, high levels of good cholesterol HDL did not do as much for the heavy drinkers"

Human Papilloma Virus Vaccines May Decrease Chances Of Oral Cancer - Science Daily, 8/30/07 - "oral and oropharyngeal squamous cell carcinoma (OOSCC) have been linked to high-risk HPV strains, the same strains that cause cervical cancer ... It's possible that oral and oropharyngeal cancers could be reduced if vaccination were more widespread; however, additional research is needed"

Antioxidant To Retard Wrinkles Discovered - Science Daily, 8/30/07 - "Antioxidants operate against free radicals which cause a breakdown of many tissues in the body, including the skin. When found in small quantities in the body, free radicals are not harmful and are even involved in various physical processes. When there is an excess of free radicals, however, as occurs during normal aging or as a result of excessive exposure to ultra-violet radiation from the sun, the result, among other things, is a breakdown of the collagen and elastin fibers in the skin. When this happens, there is a loss of skin elasticity and the formation of wrinkles ... A problem with many of the commercial antioxidants found today in the market that are said to retard the aging process is that they oxidize quickly and therefore their efficiency declines with time"

High Hostility Linked with Poor Ability to Cope With Stress, Low HDL Levels - Medscape, 8/30/07 - "individuals who were very hostile were more likely to perceive problems as stressful and to cope with stress by using interpersonal hostility, self-blame, and social isolation; they also tended to have lower levels of HDL"

Flaxseed Shows Potential To Reduce Hot Flashes - Science Daily, 8/29/07 - "The frequency of hot flashes decreased 50 percent over six weeks, and the overall hot flash score decreased an average 57 percent for the women who completed the trial. Participants also reported improvements in mood, joint or muscle pain, chills and sweating; which significantly improved their health-related quality of life" - See flax seed at Amazon.com.

Household Mold Linked To Depression - Science Daily, 8/29/07 - "Shenassa said that given the results of the current study, he wouldn’t be surprised if there is a cause-and-effect association. Molds are toxins, and some research has indicated that these toxins can affect the nervous system or the immune system or impede the function of the frontal cortex, the part of the brain that plays a part in impulse control, memory, problem solving, sexual behavior, socialization and spontaneity"

Ovary removal may cause dementia risk - USA Today, 8/29/07 - "women who'd had one or both ovaries removed showed about a 50% increase in risk of the later mental problems"

Who Should Get the HPV Vaccine? - Time Magazine, 8/28/07 - "From a public health standpoint, that logic seems to makes sense. Since 80% of women who have sex will acquire the virus by age 50 (in most cases it causes no health problems and clears the body within two years), it accomplishes little to give the vaccine to older, sexually active women, who may already have HPV or have already spread it within the community. But humanpapillomavirus isn't a single virus; rather, it's a family of viruses that includes at least 100 strains, more than 30 of which are transmitted sexually. About 10 of those can cause cervical cancer; others may cause genital warts. So even if a woman has been exposed to one strain of HPV, there may well be others that she is still vulnerable to. HPV also poses a threat to men because genital warts can develop into oral cancer, and a new study in the medical journal Cancer suggests that young men be vaccinated against HPV"

Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds:

Dietary fiber intake and risk of postmenopausal breast cancer defined by estrogen and progesterone receptor status-A prospective cohort study among Swedish women - Int J Cancer. 2007 Aug 31 - "estrogen receptor (ER)/progesterone receptor (PR)-defined breast cancer risk ... When comparing the highest to the lowest quintile, we observed non-significant inverse associations between total fiber intake and the risk of all tumor subtypes; the multivariate-adjusted RRs were 0.85 (95% CI: 0.69-1.05) for overall, 0.85 (0.64-1.13) for ER+PR+, 0.83 (0.52-1.31) for ER+PR- and 0.94 (0.49-1.80) for ER-PR-. For specific fiber, we observed statistically significant risk reductions for overall (34%) and for ER+PR+ (38%) for the highest versus lowest quintile of fruit fiber, and non-significant inverse associations for other subtypes of cancer and types of fiber. Among ever-users of postmenopausal hormone (PMH), total fiber intake and especially cereal fiber were statistically significantly associated with approximately 50% reduced risk for overall and ER+PR+ tumors when comparing the highest to the lowest quartile, but no association was observed among PMH never users"

ApoB/apoA-I ratio: an independent predictor of insulin resistance in US non-diabetic subjects - Eur Heart J. 2007 Sep 1 - "In the US population, apoB/apoAI ratio is significantly associated with insulin resistance in non-diabetic subjects"

Use of Statins and Blood Pressure - Am J Hypertens. 2007 Sep;20(9):937-941 - "Compared with people not using statin medication, significantly more statin users had their blood pressure under control (52.2% v 38.0%). After adjustment for demographic factors, statin users were two times (95% confidence interval [CI], 1.46 to 2.72) more likely to have their blood pressure under control (<140/90 mm Hg) than nonusers. After further adjustment for body mass index, diabetes, smoking, exercise, low-salt diet, and antihypertensive medications, the likelihood of having blood pressure under control remained more likely among statin users (odds ratio, 1.46; 95% CI, 1.05 to 2.05)"

The red clover (Trifolium pratense) isoflavone biochanin A inhibits aromatase activity and expression - Br J Nutr. 2007 Aug 29;:1-8 - "Biochanin A is an isoflavone isolated from red clover (Trifolium pratense) ... Isoflavones resemble the structure of oestrogen, and display agonistic and antagonistic interactions with the oestrogen receptor. Overexposure of oestrogen is a major contributing factor in the development of breast cancer ... In the present study the effect of biochanin A on the gene regulation and enzyme activity of aromatase was investigated. By assaying MCF-7 cells stably transfected with CYP19, biochanin A inhibited aromatase activity and hampered cell growth attributing to the enzyme activity" - See red clover at Amazon.com.

Liver dysfunction in paediatric obesity: a randomized, controlled trial of metformin - Acta Paediatr. 2007 Sep;96(9):1326-32 - "In obese adolescents fed ad libitum, metformin (a) prevented the rise in ALT concentrations that were observed in placebo-treated subjects at the 3 to 5 month time-points (p < 0.05); (b) reduced (p < 0.01) the percentage of all ALT values exceeding 40 U/L; and (c) caused a modest (10%) but statistically significant (p < 0.05) reduction in serum ALT in Caucasian subjects. Metformin had no effect on ALT levels or the ALT to AST ratio in the five African American adolescents enrolled in the study ... metformin might reduce the rates or severity of liver dysfunction in selected high-risk adolescents"

Effect of long-term treatment with rosiglitazone on arterial elasticity and metabolic parameters in patients with Type 2 diabetes mellitus: a 2-year follow-up study - Diabet Med. 2007 Aug 24 - "In patients treated with rosiglitazone for 2 years: the large artery elasticity index (LAEI) increased from 10.0 +/- 4.6 to 13.9 +/- 4.7 ml/mmHg x 100 after 2 years (P = 0.003). The small artery elasticity (SAEI) index increased significantly from 3.2 +/- 1.2 to 5.1 +/- 1.9 (P < 0.0001). In patients who discontinued rosiglitazone: LAEI did not change after 6 months, but decreased from 12.1 +/- 5.4 to 8.9 +/- 3.9 ml/mmHg x 10 (P < 0.0001) at the end of 2 years. SAEI increased during the first 6 months of treatment, from 3.9 +/- 1.8 to 5.1 +/- 1.5 ml/mmHg x 100 (P < 0.0001) and decreased after discontinuation of rosiglitazone (P = 0.042)"

Nutritional intervention to reduce the n-6/n-3 fatty acid ratio increases adiponectin concentration and fatty acid oxidation in healthy subjects - Eur J Clin Nutr. 2007 Aug 15 - "Dietary intervention was associated with significant reductions in TNF-alpha (baseline: 2.2 (s.d. 0.3), post-intervention: 1.5 (s.d. 0.3) pg/ml, P=0.01) and low-density lipoprotein-cholesterol (baseline: 2.5 (s.d. 0.2), post-intervention: 2.3 (s.d. 0.1) mmol/l, P=0.03) and increased adiponectin (baseline: 6.5 (s.d. 0.7), post-intervention: 7.6 (s.d. 0.6) mug/ml, P=0.02). Fasting lipid oxidation was increased (baseline: 0.7 (s.d. 0.1), post-intervention: 0.9 (s.d. 0.1) mg/kg.min, P=0.01), whereas glucose oxidation decreased in both fasting (baseline: 1.6 (s.d. 0.1), post-intervention: 1.3 (s.d. 0.1) mg/kg.min, P=0.02) and hyperinsulinaemic conditions (baseline: 3.6 (s.d. 0.1), post-intervention: 3.3 (s.d. 0.1) mg/kg.min, P=0.04). Insulin sensitivity was not affected by the intervention.  Conclusion: A decreased n-6/n-3 PUFA ratio can be achieved with simple dietary counselling, resulting in multiple, potentially favourable effects on the metabolic and inflammatory profiles"

Inflammation, Metabolic Syndrome, Erectile Dysfunction, and Coronary Artery Disease: Common Links - Eur Urol. 2007 Aug 13 - "Increased circulating levels of inflammatory and endothelial-prothrombotic compounds are related to the presence and severity of ED"

Vitamin D in preventive medicine: are we ignoring the evidence? - Br J Nutr 2003 May;89(5):552-572 - "European children and young adults often have circulating 25(OH)D levels in the insufficiency range during wintertime. Elderly subjects have mean 25(OH)D levels in the insufficiency range throughout the year. In institutionalized subjects 25(OH)D levels are often in the deficiency range. There is now general agreement that a low vitamin D status is involved in the pathogenesis of osteoporosis. Moreover, vitamin D insufficiency can lead to a disturbed muscle function. Epidemiological data also indicate a low vitamin D status in tuberculosis, rheumatoid arthritis, multiple sclerosis, inflammatory bowel diseases, hypertension, and specific types of cancer. Some intervention trials have demonstrated that supplementation with vitamin D or its metabolites is able: (i) to reduce blood pressure in hypertensive patients; (ii) to improve blood glucose levels in diabetics; (iii) to improve symptoms of rheumatoid arthritis and multiple sclerosis. The oral dose necessary to achieve adequate serum 25(OH)D levels is probably much higher than the current recommendations of 5-15 &mgr;g/d."

Total calcium intake was not associated with hip fracture risk (RR = 0.96; 95% CI: 0.68, 1.34 for 1200 compared with < 600 mg/d). Milk consumption was also not associated with a lower risk of hip fracture (P for trend = 0.21)"
