The Nutrition InvestigatorThe health and nutrition blog by Dr. Roc Ordman.

There is so much legitimate nutrition news I am nearly overwhelmed. Though it makes life even more challenging that my house was destroyed in a fire Dec. 6th, along with almost all of my possessions. And that classes have just begun. But the news is so exciting, that I have actually revised the supplements that the scientific literature now justify as safe and proven that you might decide to take after you have shown the peer-reviewed publications and discussed them with your doctor. That evidence is in the articles that are summarized below and linked here: http://link.springer.com/journal/11357/35/1/page/1

Those articles support my revised supplement charts found at Supplements to consider by age and gender:http://chemistry.beloit.edu/Ordman/nutrition/indices/iformula.htm

1.Androgen depletion in humans leads to cavernous tissue reorganization and upregulation of Sirt1–eNOS axis – Translation: Thinking about sex is good for your health.
2.  Fatigability as a function of physical activity energy expenditure in older adults – Translation: Stay physically fit through exercising regularly.
3. High serum glucose levels are associated with a higher perceived age – Translation: When you consume sugar, for instance soft drinks, it causes wrinkles, so people who drink pop look much older when they mature than those who do not.
4. A complex dietary supplement augments spatial learning, brain mass, and mitochondrial electron transport chain activity in aging mice– Key ingredients include those found in Juvenon – lipoic acid and N-acetyl-carnitine – molecules we make naturally when young that are depleted with age (20? 40?) and metabolically prevent weight gain and memory loss.
5. The effect of resveratrol on lifespan depends on both gender and dietary nutrient composition in Drosophila melanogaster – Lifespan extension by resveratrol was associated with downregulation of genes in aging-related pathways.
6. Aging and vascular dysfunction: beneficial melatonin effects – Melatonin is known to modulate oxidative stress-induced senescence and pro-survival pathways.

Researchers had one group meditate, one exercise, and one as a control.  Those who meditated missed 76% fewer days of work, those who exercised missed 48% fewer. -Sci Am. Mind Nov/Dec ’12
