Archive for January, 2011 – A new laboratory study of the anti-aging effects of calorie restriction reveals that a likely mechanism by which calorie restriction extends lifespan is boosting the level of pyruvate in cells. The pyruvate then causes a repeated or chronic low-level oxidative stress in the body that induces a cellular response (akin to exercise stress) […]

A deficiency of omega-3 fatty acids in Western diets has been implicated in many disorders. A new laboratory study of a diet low in omega-3 fatty acids has shown that reduced levels of omega-3 had deleterious consequences on brain synaptic functions and emotional behavior. Specifically the study revealed that without adequate omega-3s, the receptors in […] – How you prepare broccoli and consume your broccoli matters, and also suggests that teaming broccoli with broccoli sprouts may make the vegetable’s anti-cancer effect almost twice as powerful, according to a new University of Illinois study. “Broccoli, prepared correctly, is an extremely potent cancer-fighting agent – three to five servings a week are […] – Scientists are reporting discovery of a potential biochemical basis for the apparent cancer-fighting ability of broccoli and its cruciferous vegetable cousins. They found for the first time that certain substances – isothiocyanates – in the vegetables appear to target and block a defective gene associated with cancer. The report of their NIH-funded research, […]

A new study provides insight into how stress impacts the brain and may help to explain why some individuals are predisposed to depression when they experience chronic stress. The research, published by Cell Press in the January 27, 2011 issue of the journal Neuron, reveals complex molecular mechanisms associated with chronic stress and may help […]

Eating trans-fats and saturated fats increase the risk of suffering depression, and olive oil protects against this mental disorder, according to research from the universities of Navarra and Las Palmas de Gran Canaria. The relation between types of dietary fat and depression was confirmed after studying 12,059 SUN Project volunteers over the course of six […]
