Drinking 8 Glasses Of Water A Day Is ‘Nonsense,’ Doc Says

The health recommendation to drink six to eight glasses of water a day is “thoroughly debunked nonsense,” a doctor wrote this week in a commentary in the British Medical Journal.

Many health departments and organizations tout the need to drink that much water every day, but there is no high-quality scientific evidence to support the recommendation, wrote Dr. Margaret McCartney, a general practitioner based in Scotland.

Some organizations backed by bottled-water makers — such as Hydration for Health, created by the makers of Volvic and Evian — say that it’s important to drink 1.5 to 2 liters (about 6 to 8 cups) of water a day, and that being even mildly dehydrated plays a role in disease development, McCartney wrote.

However, no such claims have ever been confirmed in studies, she said, and drinking too much water can actually be dangerous by causing low blood sodium levels (a condition called hyponatraemia) and exposing people to pollutants in the water.

“People still think that we’re all going to die or our kidneys will shrivel up if we don’t drink eight cups of water a day,” McCartney told Postmedia News. “From what I can see, there’s never been any evidence in the medical literature about it.”

The first recommendation to drink six to eight glasses of water a day has been traced back to a 1945 U.S. research paper, but even that isn’t for certain, Postmedia News reported.

The Guardian reported that humans’ thirst mechanisms are so sophisticated that if our bodies are in need of water, they’ll let us know by making us thirsty.

What to Eat to Beat Skin Cancer

You got the pale-is-the-new-tan memo years ago and have the sun smarts to prove it. Skin cancer is the most common cancer in the United States, and women age 39 and under have a higher probability of developing its most serious form, melanoma, than they do any other invasive cancer except breast cancer.

Yep; knew that. Slather on waterproof sunscreen before you exercise, sport floppy broad-brimmed hats at the beach, stay out of midday rays, and steer clear of tanning beds. Check; do all that. Still, despite your savvy and diligence, there’s a new stealth skin saver you may be missing: your diet.

“The research is preliminary but promising,” says Karen Collins, RD, clinical dietitian and nutrition adviser for the American Institute for Cancer Research in Washington, D.C. “In addition to limiting your sun exposure, eating certain foods may help reduce your risk.”

Obama Publicly Backs Means-Testing Medicare

WASHINGTON - President Barack Obama formally acknowledged on Friday that he would support a plan to means-test Medicare as a part of a deal to raise the nation’s debt ceiling.

“I have said that means-testing on Medicare, meaning people like myself — I’m going to be turning 50 in a week, so I’m starting to think a little bit more about Medicare eligibility — but you can envision a situation for somebody in my position, me having to pay a little bit more on premiums or co-pays would be appropriate. And again, that would make a difference,” the president said at a press conference. “What we are not willing to do is restructure the program in the ways we have seen coming out of the House in recent months.”

The comment was the first public acknowledgment from the White House that the president would support changing the payment structure of the entitlement program. Prior to Obama’s remarks, multiple sources in both parties told The Huffington Post that the administration was making it clear to debt ceiling negotiators that such a structural change to Medicare was on the table.

The proposal is not entirely controversial among health care economists. But it will rankle a good chunk of the president’s own party, which has sought to keep Medicare’s structure as a basic insurance program. Medicare premiums for doctors and for prescription drugs are already means tested. Making top earners pay even more — while potentially sound policy — opens the program to politically potent charge that it is health care welfare for lower income Americans.

The Obama administration’s embrace of the idea came during talks between lawmakers and Vice President Joseph Biden. The exact contours of what was proposed are not entirely clear. But a version that House Majority Leader Eric Cantor (R-Va.) proposed in later discussions would have saved the government an estimated $38 billion by charging those high-income beneficiaries 10 percent more for the cost of hospital stays and prescription drugs.

Obama’s nominal support for means-testing Medicare, however, does fit into the larger outlines of his plan for the debt ceiling debate. In an effort to both win the support of Republicans and tackle as many deficit-contributing issues as possible, the administration has placed entitlement programs like Social Security and Medicare (“sacred cows” for the Democratic Party) squarely on the table. The president also lent his support to a plan to raise the eligibility age of Medicare from 65 to 67, over the course of roughly 25 years. His team has, additionally, discussed various changes to the way in which Social Security benefits are measured and paid.
