Save Energy to Burn More Calories. Decreasing the Environment Temperature to 19°C and Burn 6% More Calories at Rest

Written by | published on
On the northern hemisphere, the days get shorter and the temperatures are falling. I hope you have not turned up your heatings, yet. It is not only the environment that may benefit from a more conscious management of the room temperature. As scientists from the Clinical Endocrinology Branch, NIDDK-NIH, Bethesda have found, reducing room temperature by 6°C (from 24°C to 19°C) will increase human energy expenditure (EE) be 6%! Exposure to 19° C resulted in an increase in plasma and urine norepinephrine levels (p<0.0001), and a 5.96 % (p<0.001) increase in energy expenditure without significant changes in spontaneous physical activity . Exposure to the lower temperature resulted in a significant increase in free fatty acid levels (p<0.01), fasting insulin levels (p<0.05), and a marginal decrease in postprandial glucose levels. A small but significant (p<0.002) increase in serum free T4 and urinary free cortisol (p<0.05) were observed at 19° C. This is of part...

Vitamin C Against Infections? For Men Only!

Written by | published on
Researchers ( Constantini. 2010 ) from the University medical center in Jerusalem found that contrary to popular believe, vitamin C will not help ward off the common cold in swimmers. Interestingly, they did observe a positive effect on severity and duration of infection in males, only: The duration of respiratory infections was 22% shorter in vitamin C group, but the difference was not statistically significant. However, we found a significant interaction between vitamin C effect and sex, so that vitamin C shortened the duration of infections in male swimmers by 47% (95% CI: -80% to -14%), but had no effect on female swimmers (difference in duration: +17%; 95% CI: -38% to +71%). The effect of vitamin C on the severity of URIs was also different between male and female swimmers, so that vitamin C was beneficial for males, but not for females. Hitherto, the scientists have no explanation for the observed gender bias. It could however have contributed to the equivocal  resul...

Juice Plus does not Prevent Common Colds, but Shortens Phases With Severe Symptoms

Written by | published on
If you are like me, you probably like very concrete studies. Studies such as the one published by Roll et al. in the British Journal of Nutrition ( Roll. 2011 ). In a randomised, double-blind, placebo-controlled trial, the scientists investigated the effect of 4 capsules of Juice+ on healthcare professionals (mainly nursing staff aged 18–65 years) from a university hospital in Berlin, Germany. The results are not earth-shattering, but interesting nonetheless. While supplementation did not decrease the mean number of days the subjects experienced "common cold symptoms", it did decrease the number of days with "severe" symptoms. The scientists summarize their results as follows: Intake of a dietary supplement from fruits and vegetables was associated with a 20 % reduction of moderate or severe common cold symptom days in healthcare professionals particularly exposed to patient contact. Whether you think this is worth the extra bucks for supplements you would not...
