The concept that nature provides stress relief gained momentum during the early 19th century when Henry David Thoreau and Ralph Waldo Emerson, among others, began the transcendentalist movement. Past research has illustrated the many benefits of spending time in greener settings. This study considered the effects of different environments on several measures of stress.
Using a randomized double-blind placebo-controlled clinical trial, this study examined the effects of resveratrol in lowering blood glucose and other related outcomes (eg, insulin, metabolic markers, cardiovascular risk factors) in patients with type 2 diabetes.
The latest in a series of articles on beetroot as a performance-enhancer looked at the effects of the juice on cyclists' performance at high altitude. The study found that drinking beetroot juice increased plasma nitrate and nitrate levels, lowered VO2, and improved speed.
Cardiovascular disease is the leading cause of morbidity and mortality among the US population. Aged garlic extract helps to modulate multiple cardiovascular risk factors by lowering blood pressure, inhibiting platelet aggregation and adhesion, lowering cholesterol, and preventing LDL oxidation and smoking-induced oxidative damage.
This was an 8-week pilot study of daily yogic meditation versus relaxation in mildly depressed, elderly caregivers of dementia patients. The intervention group practiced Kundalini yoga with Kirtan Kriya meditation for 12 minutes daily; the placebo group listened to a prescribed relaxation CD for the same length of time. Measures of depression, mental health, cognitive function, and telomerase activity were assessed.
This publication pulled together data from several studies, both mouse and human, to assess the role of trimethylamine-N-oxide (TMAO) on atherosclerosis. TMAO is a product of carnitine metabolism by microbiota in the gut.
After 8 weeks, participants consuming the high and intermediate flavanol cocoa products did significantly better on both trail-making tests; had significantly better verbal fluency scores; and had significantly reduced insulin resistance, blood pressure, blood glucose, and levels of lipid peroxidation. None of these test results changed in participants who consumed the low-flavanol cocoa.
Infants who were introduced to fish between 6 and 12 months had a statistically significant lower incidence of wheezing at 48 months when compared to infants who were not introduced to fish in the first year of life. Infants who were introduced to fish between 0 and 6 months had slightly higher risk of wheezing at 48 months. The consumption of less than 1/2 serving per week of fatty fish was associated with a significantly higher incidence of wheezing at 48 months.
