Newsweek Slams Antioxidants: Yawn! (nutraingredients-usa.com)
On January 25, Newsweek published an article entitled “Antioxidants Fall From Grace: The popular dietary components may not do any good, and may actually harm.” The article treads the same old path of “antioxidant supplements do not work, and one big meta-analysis indicated they may increase your risk of mortality.”
One word: Yawn.
The world of antioxidants is moving onwards, and repeating the same old line is not benefiting anyone: Not consumers, nor industry. For those at the cutting edge of antioxidant research, now is the time to show where the science is going…More…
The 2010 Dietary Guidelines: Enjoy Your Food, but Eat Less! (Food Politics)
I’m in shock. I never would have believed they could pull this off. The new guidelines recognize that obesity is the number one public health nutrition problem in America and actually give good advice about what to do about it: eat less and eat better….Overall, the new guidelines aren’t perfect but they are a great improvement…More…
How to Get the Best Out of Broccoli (Futurity.org)
“Broccoli, prepared correctly, is an extremely potent cancer-fighting agent—three to five servings a week are enough to have an effect,” says Elizabeth Jeffrey, professor of nutrition at the University of Illinois.
“To get broccoli’s benefits, though, the enzyme myrosinase has to be present; if it’s not there, sulforaphane, broccoli’s cancer-preventive and anti-inflammatory component, doesn’t form.”
Overcooking broccoli destroys myrosinase, Jeffrey says—and powder supplements often don’t contain it. “Steaming broccoli for two to four minutes is the perfect way to protect both the enzyme and the vegetable’s nutrients.”
The study was published in the journal Nutrition and Cancer…More…
When Meal Times No Longer Focus on Food (ScienceNews)
There’s little doubt that humanity has been tipping the scales at increasingly higher weights and rates. A study now lends support to the idea that meal-time distractions can mask the cues that we really have eaten quite enough. Moreover, it finds, the caloric fallout of not paying attention to what we’re eating doesn’t necessarily end when a meal is over…More…
How maternal essential fatty acid deficiency impact on its progeny is poorly understood. Dietary insufficiency in omega-3 fatty acid has been implicated in many disorders. Researchers from Inserm and INRA and their collaborators in Spain collaboration, have studied mice fed on a diet low in omega-3 fatty acid. They discovered that reduced levels of omega-3 had deleterious consequences on synaptic functions and emotional behaviours.
Details of this work are available in the online version of the journal Nature Neuroscience…More…
How Meditation May Change the Brain (NY Times)
The researchers report that those who meditated for about 30 minutes a day for eight weeks had measurable changes in gray-matter density in parts of the brain associated with memory, sense of self, empathy and stress. The findings…appear in the Jan. 30 issue of Psychiatry Research: Neuroimaging.
M.R.I. brain scans taken before and after the participants’ meditation regimen found increased gray matter in the hippocampus, an area important for learning and memory. The images also showed a reduction of gray matter in the amygdala, a region connected to anxiety and stress. A control group that did not practice meditation showed no such changes…More…
