Many Psychotropic Medications May Be Bad for Bones - Medscape, 5/27/10 - "osteoporosis was found to be associated with the use of selective serotonin reuptake inhibitors (SSRIs), mood stabilizers other than lithium, and benzodiazepines. Use of tricyclic antidepressants was protective"

Supplement may prevent alcohol-related brain, skull defects - Science Daily, 5/27/10 - "The dietary supplement CDP-choline, sold as a brain-boosting agent and under study for stroke and traumatic brain injury, may block skull and brain damage that can result from alcohol consumption early in pregnancy ... 25 percent of mouse embryos exposed to alcohol during that critical period had defects in the fibrous joints that connect the skull ... When they added ceramide-neutralizing CDP-choline to the mouse cells, cell death and ceramide levels were reduced" - See citicholine at Amazon.com.

High blood cortisol levels significantly increases death rate in patients with acute coronary syndrome - Science Daily, 5/27/10 - "1036 patients with acute coronary syndrome were studied for an average period of 7.7 years. There were no significant differences in the serum cortisol levels between patients with and without acute coronary syndrome. However, the patients with ACS and high cortisol levels had a significantly elevated number of deaths when compared to the patients with ACS and the lowest cortisol levels. 758 total deaths were reported during the follow-up period. The ACS patients with the highest cortisol levels (i.e. the highest 25% serum cortisol) were significantly more likely to die from fatal cardiovascular events than those with the lowest cortisol levels (the lowest 25% serum cortisol). (The hazard ratio for highest versus lowest quartile of SCC was 1.89"

Brief exercise reduces impact of stress on cell aging, study shows - Science Daily, 5/27/10 - "A growing body of research suggests that short telomeres are linked to a range of health problems, including coronary heart disease and diabetes, as well as early death ... In the study, 62 post-menopausal women -- many of whom were caring for spouses or parents with dementia ... when participants were divided into groups -- an inactive group, and an active group (i.e., they met federal recommendations for 75 minutes of weekly physical activity) -- only the inactive high stress group had shorter telomeres. The active high stress group did not have shorter telomeres. In other words, stress predicted shorter telomeres in the sedentary group, but not in the active group"

Advanced Glycation End Products in Foods and a Practical Guide to Their Reduction in the Diet - J Am Diet Assoc. 2010 Jun;110(6):911-916.e12 - "Modern diets are largely heat-processed and as a result contain high levels of advanced glycation end products (AGEs). Dietary advanced glycation end products (dAGEs) are known to contribute to increased oxidant stress and inflammation, which are linked to the recent epidemics of diabetes and cardiovascular disease ... Based on the findings, dry heat promotes new dAGE formation by >10- to 100-fold above the uncooked state across food categories. Animal-derived foods that are high in fat and protein are generally AGE-rich and prone to new AGE formation during cooking. In contrast, carbohydrate-rich foods such as vegetables, fruits, whole grains, and milk contain relatively few AGEs, even after cooking. The formation of new dAGEs during cooking was prevented by the AGE inhibitory compound aminoguanidine and significantly reduced by cooking with moist heat, using shorter cooking times, cooking at lower temperatures, and by use of acidic ingredients such as lemon juice or vinegar"

Non-steroidal anti-inflammatory drug (NSAID) use and breast cancer risk in the Western New York Exposures and Breast Cancer (WEB) Study - Cancer Causes Control. 2010 May 25 - "Recent aspirin use was inversely associated with breast cancer risk (adjusted OR 0.80, 95% CI: 0.68-0.94); the strongest reduction in risk was observed among those who took >/=2 pills/day on days that aspirin was taken (OR 0.74, 95% CI: 0.61-0. 90). Adult lifetime use was also associated with breast cancer risk (>10 days/month, adjusted OR 0.68, 95% CI: 0.46-1.00). Use of ibuprofen or acetaminophen was not associated with breast cancer"

  • Why whole grains are protective: biological mechanisms - Proc Nutr Soc 2003 Feb;62(1):129-34 - "First, whole grains are concentrated sources of dietary fibre, resistant starch and oligosaccharides, carbohydrates that escape digestion in the small intestine and are fermented in the gut, producing short-chain fatty acids (SCFA). SCFA lower colonic pH, serve as an energy source for the colonocytes and may alter blood lipids. These improvements in the gut environment may provide immune protection beyond the gut. Second, whole grains are rich in antioxidants, including trace minerals and phenolic compounds, and these compounds have been linked to disease prevention. Additionally, whole grains mediate insulin and glucose responses. Although lower glycaemic load and glycaemic index have been linked to diabetes and obesity, risk of cancers such as colon and breast cancer have also been linked to high intake of readily-available carbohydrate. Finally, whole grains contain many other compounds that may protect against chronic disease. These compunds include phytate, phyto-oestrogens such as lignan, plant stanols and sterols, and vitamins and minerals."
  • Whole grains protect against atherosclerotic cardiovascular disease - Proc Nutr Soc 2003 Feb;62(1):135-42 - "Generous intake of whole grains also provides protection from development of diabetes and obesity. Diets rich in wholegrain foods tend to decrease serum LDL-cholesterol and triacylglycerol levels as well as blood pressure while increasing serum HDL-cholesterol levels. Whole-grain intake may also favourably alter antioxidant status, serum homocysteine levels, vascular reactivity and the inflammatory state. Whole-grain components that appear to make major contributions to these protective effects are: dietary fibre; vitamins; minerals; antioxidants; phytosterols; other phytochemicals. Three servings of whole grains daily are recommended to provide these health benefits"
