School starting in 2 weeks. Just visited grandchildren and swam in the ocean. Living on veggies from my bountiful garden. I am so fortunate.
FEATURE (from Scientific American Mind-Sept/Oct 12 pg 18): Open Mind, Longer Life – The trait of openness improves health through creativity, and predicts longer life. A study in the Journal of Aging and Health found only creativity – not intelligence or overall openness – decreased mortality risk, possibly because it draws on many neural networks throughout the brain.
THE JOURNAL of NUTRITION ARTICLES THIS MONTH
1. Resveratrol and quercetin (esp. in tea) work synergistically, esp. for arterial health. Restenosis is a critical complication of angioplasty and stenting. Restenosis is multifactorial, involving endothelial injury, inflammation, platelet activation, and vascular smooth muscle cell (VSMC) proliferation. Resveratrol (R) and quercetin (Q) are polyphenols that are known to exhibit vascular protective effects. In conclusion, in combination, R and Q can interact to reduce the extent of restenosis, perhaps due to their synergistic inhibition of VSMC proliferation and inflammation.
2. Obesity causes nonalcoholic fatty liver disease – Nonalcoholic fatty liver disease (NAFLD)7 has increased in parallel with central obesity, and its prevalence is anticipated to continue to increase. NAFLD is now the most common cause of liver disease in developed countries (3) and is defined as excessive lipid accumulation in the liver, i.e., hepatosteatosis (4, 5). The American Liver Foundation estimates that ~25% of the U.S. population has NAFLD and 75% of obese and 100% of morbidly obese individuals have NAFLD. Metabolic syndrome risk factors include obesity, elevated plasma TG and LDL cholesterol, reduced HDL cholesterol, high blood pressure, and fasting hyperglycemia.
3. Getting only 600 IU of vitamin D is insufficient for cardio-metabolic health – Men and women aged 20–40 y (n = 202) and ≥64 y (n = 192) received cholecalciferol up to 600 IU daily. Putative effects of vitamin D on cardio-metabolic health will only be evident at higher intakes than the current RDA of 600 IU and possibly in individuals at particular risk of CVD risk.
4. Mediterranean diet inversely associated with mortality – In men, but not in women, the score was inversely associated with total cancer mortality, particularly for pancreas cancer. Cardiovascular mortality was inversely associated with diet only in women and fruit intake, no food item of the Mediterranean diet score independently predicted mortality. Higher scores were associated with increasing age, education, and physical activity. Moreover, healthful dietary and lifestyle-related factors additively decreased the mortality likelihood. Even in a subarctic region, increasing Mediterranean diet scores were associated with a longer life, although the protective effect of diet was of small magnitude compared with other healthful dietary and lifestyle-related factors examined.
5. Low vitamins B6 and B12 status associated with impaired cognition and depression – Low plasma vitamin B-12 concentrations were associated with poorer MMSE scores and higher depression scores, and low vitamin B-6 concentrations were associated with lower MMSE and worse attention and executive function in the multivariate analysis.
6. Having children usually leads to poorer diets in women – Women living with children had greater energy intake than other women initially and those who started a family had the greatest increases over time. Five similar dietary patterns were derived from both surveys. Women living in a family at both times had higher scores on the high-fat and sugar, meat, and cooked vegetables patterns and lower scores on the Mediterranean-style and fruit patterns than other women. Women starting a family increased their consumption of the high-fat and sugar, fruit, and cooked vegetables patterns. Women not living with children at both times had increased scores on the Mediterranean-style pattern and decreased scores on the high-fat and sugar and cooked vegetables patterns compared with other women. In conclusion, starting a family is associated with changes in women’s diet that are mainly unhealthy.
7. Vitamin A important for getting an effective vaccination – The ability of oral retinoids to stimulate systemic immunity has implications for public health and therapeutic use of Vitamin A.
8. Fish oil during pregnancy enhances breast milk quality – Fish oil supplementation during pregnancy alters breast milk composition. Salmon consumption during pregnancy also alters fatty acid composition and secretory IgA concentration in human breast milk.
