Are Vitamins Killing Women? Really?

From the title of the article below, pulled from Yahoo!, you would conclude that the researchers, who that think taking supplements increase a woman’s chance of death, are just plain morons.

Vitamins May Increase Women's Risk of Dying, Research Finds, by Joseph Brownstein of Live Science, (for the article click here)

Popping vitamins may do more harm than good, according to a new study that adds to a growing body of evidence suggesting some supplements may have health risks. Researchers from the University of Minnesota examined data from more than 38,000 women taking part in the Iowa Women's Health Study, an ongoing study with women who were around age 62 at its start in 1986. The researchers collected data on the women's supplement use in 1986, 1997 and 2004.

Women who took supplements had, on average, a 2.4 percent increased risk of dying over the course of the 19-year study, compared with women who didn't take supplements, after the researchers adjusted for factors including the woman's age and calorie intake.

"Our study, as well as other similar studies, have provided very little evidence that commonly used dietary supplements would help to prevent chronic diseases," said study author Jaakko Mursu, an epidemiologist at the University of Minnesota School of Public Health.

"We would advise people to reconsider whether they need to use supplements, and put more emphasis on a healthy diet instead," Mursu said.

MyAchingKnees comment: No doubt one should avoid bad foods and consume only healthy foods; get a moderate amount of physical exercise and activity; and, avoid toxins or a toxic environment;...... but, with today’s food supply be as low as quality as it is, taking high quality nutritional supplements is a necessity since we just cannot get all the nutrients our bodies need through foods.

A toxic combination?

The new study linked a number of individual vitamins and minerals to the slight mortality risk, including multivitamins, vitamin B6, folic acid, iron, magnesium, zinc and copper. For example, of the 12,769 women in the study who took a daily multivitamin, 40.8 percent had died by the end of 2008, whereas 39.8 percent of the 10,161 women who hadn't taken a daily multivitamin had died.

MyAchingKnees comment: Yes look at those numbers again,….40.8 percent versus 39.8 percent. The researchers are basing their conclusion on 1%. Really?

Mursu said that the design of the study did not allow the researchers to determine if there was a specific cause for the increased mortality.

"However, we do know that most compounds are toxic in high amounts, and long-term use might predispose [a person] to detrimental outcomes," he told MyHealthNewsDaily. The increased chance of dying" could be related to generally high concentration of compounds that these supplements contain. Most supplements contain higher amounts of nutrients than would be derived from food, and it is known that several compounds can be toxic in higher amounts, especially when consumed for a long time, as some of these accumulate to body," Mursu said.

Taking calcium supplements, on the other hand, actually seemed to lower the woman's death risk slightly, by 3.8 percent, although the researchers noted that there was not a relationship between consuming increasingly higher amounts of calcium and a continuing decrease in mortality rate.

Less is more!

While vitamins and minerals are necessary for proper nutrition, excess intake has not shown further benefit, and recent studies have cast some doubt on the idea that vitamin supplements provide a "safety net" for people not getting enough of a given nutrient. Instead, too much may be a problem. The study, published today (Oct. 10) in the journal Archives of Internal Medicine, is part of a series examining interventions in medicine that may be unnecessary. "Until recently, the available data regarding the adverse effects of dietary supplements has been limited and grossly under reported. We think the paradigm "the more, the better" is wrong," wrote Dr. Goran Bjelakovic and Dr. Christian Gluud, of the Center for Clinical Intervention Research at Copenhagen University Hospital in Denmark in an accompanying commentary.

"We believe that for all micronutrients, risks are associated with insufficient and too-large intake. Low levels of intake increase the risk of deficiency. High levels of intake increase the risk of toxic effects and disease," they wrote.

MyAchingKnees comment: If “high levels of (supplement) intake increase the risk of toxic effects and disease” then why hasn’t my wife or daughter or a hundred other ladies that I know who are taking high doses of pharmaceutical grade products laying dead right now? Hello? It’s the quality and purity of the products for one thing....

"Therefore, we believe that politicians and regulatory authorities should wake up to their responsibility to allow only safe products on the market," they wrote.

MyAchingKnees comment: Again, I am not in favor of the government controlling anymore things. They have done a bad enough job with what they do control so far. It is up to the consumer to figure out what are good products and what are worthless or even bad for you. There are plenty of resources out there. Make sure you are getting science based products rather than relying on products with fancy advertisements or emotional appeals.
