According to Yahoo! News, women who might become pregnant should not use resveratrol supplements. Pregnancy is an especially sensitive experience and women should be cautious about the substances ingested (and inhaled). After all, cigarette smoking is known to increase the risk of premature birth. Although alcohol consumption increases the risk of spontaneous abortion, it is the dose that matters. Pregnant women are advised to avoid alcohol altogether but 1 or 2 drinks once or twice a week is permitted.
Recent resveratrol headlines should have a similar caveat. Roberts and colleagues fed pregnant female macaques a diet containing 0.37% resveratrol for 9 months.
Nutrition is complex. After decades of observation and experimentation, vitamins were discovered (over 100 years ago) to be essential for life. When vitamin intakes are too low, deficiency diseases become prevalent. When vitamin intakes are inadequate and status is suboptimal, health is compromised. Just like “The Story of the Three Bears”, researchers continue efforts to determine the amount of dietary X that is “just right”.
Semba and colleagues hypothesized that resveratrol might be the elixir of life – the single entity explaining longevity.
Obesity, diabetes, and cardiovascular disease are associated with disturbed lipid metabolism. Weight loss, increasing physical activity, and reducing saturated fat and cholesterol intake can successfully modify lipid risk profiles and cardiovascular disease risk. Nevertheless, people are always looking for magic bullets. The medical profession has found their antidote to prevent cardiovascular disease: prescription drugs, primarily statins.
Most and colleagues investigated the effects of short-term supplementation of two combinations of polyphenols on energy expenditure and lipid metabolism
When my RSS reader displayed “Dark chocolate, red wine good for the heart”, it was the promise of a good day! How much more could one want? Nutrition and pleasure in the same swallow. A deeper dive into the scientific literature helps explain mechanisms of action.
Konings and colleagues report that resveratrol supplementation decreased fat cell size and altered lipid catabolism pathways.
