Why You Need More Vitamin D

Dr. Andrew Weil: 
I am raising my recommendation of 1,000 IU of vitamin D per day to 2,000 IU per day. Since 2005, when I raised it from 400 to 1,000 IU, clinical evidence has been accumulating to suggest that a higher dose is more appropriate to help maintain optimum health.
We have known for many years that we need vitamin D to facilitate calcium absorption and promote bone mineralization. But newer research has shown that we also need it for protection against a number of serious diseases. In recent years, scientists have discovered that it may help to prevent several cancers, cardiovascular disease, autoimmune disorders, psoriasis, diabetes, psychosis, and respiratory infections including colds and flu.
To focus particularly on cancer prevention, two recent meta-analyses (in which data from multiple studies is combined) conducted by the Moores Cancer Center at the University of California at San Diego and colleagues suggested that raising blood levels of vitamin D could prevent one-half of the cases of breast cancer and two-thirds of the cases of colorectal cancer in the U.S. Discussing the breast cancer analysis, study author Cedric Garland, Dr.P.H., stated that “The serum level associated with a 50 percent reduction in risk could be maintained by taking 2,000 international units of vitamin D3 daily plus, when the weather permits, spending 10 to 15 minutes a day in the sun.”

If we don't change our ways soon...
A new report by the Royal Society, chaired by Nobel prize-winning biologist Sir John Sulston warns that world population must be stabilized and consumption in wealthy nations must be reduced or the entire planet is in big trouble. As the report reads: "The number of people living on the planet has never been higher, their levels of consumption are unprecedented and vast changes are taking place in the environment. We can choose to rebalance the use of resources to a more egalitarian pattern of consumption... or we can choose to do nothing and to drift into a downward spiral of economic and environmental ills leading to a more unequal and inhospitable future."This is the same warning that President Jimmy Carter gave Americans back in the 1970's - but it was ignored when Ronald Reagan came to power with a "more positive" message basically telling Americans we can do whatever we want. And then after 9/11 - Bush told us all we should go shopping and consume ever more.And now with corporations calling the shots in Washington - long-term sustainability of the planet takes a back seat to short-term profits. If we don't change our ways soon - and embrace clean, alternative energy and educate women around the plant - then we all could be headed for a rough century.-Thom(Is there any chance we will learn in time?

The modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness.
