Question: Is whole wheat considered a whole grain? As I understand it, foods with a low glycemic index are supposed to leave you feeling fuller, take longer to digest, and have health benefits. I thought whole grains were supposed to do those things too, but I’ve also read on the Internet that there’s no difference between wheat flour and white flour. What’s the truth?
Bipolar Disorder, also known as manic–depressive disorder, is a condition characterized by alternating states of elevated energy, cognition and mood, with periods of irritable mood and depression. The extreme mood swings experienced by patients with bipolar disorder have been strongly associated with disruptions in circadian rhythms — the 24-hour cycle of biological processes that govern our day and night activity.
Lithium is one of the most common treatments for bipolar disorder. However, little research has been done to find out if and how lithium impacts the brain and peripheral body clockwork. A new study published in the open access journal PLoS ONE reveals a novel link between lithium, bipolar disorder and circadian rhythms [1].
Just as clothing styles come in and out of fashion, diagnoses go through fads as well. While this is rarely true of diagnoses issued by traditional healthcare practitioners, health-related Internet sites (particularly those promoting alternative medicine) and some practitioners of alternative medicine may be susceptible to these diagnostic trends. One such fad diagnosis is lactose intolerance, which is sometimes blamed for everything from hyperactivity to joint pain.

You really do feel hungrier than you used to, and still the pounds keep creeping back on. This is the conclusion that Dr. Joseph Proietto and his colleagues at the University of Melbourne just published in the New England Journal of Medicine [1].

Water is essential for life, yet less than 1% of water on the planet is safe to drink. This is especially a problem in developing countries or during natural disasters. Take Hurricane Katrina: back in 2005 when it hit the Gulf Coast, one of the biggest needs for storm victims was access to clean drinking water.
In the United States and Europe, people take it for granted that when they turn on the faucet, clean water will flow out. Indeed, a single flush of a toilet in the West uses more water than most Africans have to perform an entire day’s washing, cleaning, cooking and drinking [2].
Securing access to safe water worldwide is vitally important. Clean water is essential for agriculture, food and energy production, recreation and reduction of poverty. More than 2 million people, most of them children, die every year from water-borne diseases. And time is of the essence: by 2020, more people could die of water-related diseases than those that have died due to HIV/AIDS [2].
