Vitamin D,Calcium Needed For Better Bones

Calcium Needed For Better Bones

Attention to bone health is important for all ages, not just older adults. Researchers are finding a number of factors that can affect bone from conception forward. The dietary and lifestyle habits of a mother can affect the bone status of her unborn child. The years of childhood and adolescence, are when bones become longer and stronger. During middle and older age, the goal is to maintain the bone that has been acquired.

Through all these stages, nutrition is key. Vitamin D appears to play a large role beginning during pregnancy. Pregnant women need to cover their own needs as well as the needs of their child. With all the new research on this important vitamin, there is controversy as to exactly what that requirement should be, but many suggest at least a baseline intake of 1000 IU a day, some say as much as much as 2000 or more, especially for a mom of multiples.

Farmed Trout on List of Healthy Fish Choices

salmon-fibro

Salmon, tuna, and other fish are loaded with heart-healthy omega-3 fatty acids, so they must be good for you, right? Not so fast—some types of fish have more mercury than others, and others are harvested from the ocean or farmed in a way that’s harmful to the environment.

Now, a new list has come to the rescue: It sorts through the confusion by rating fish in terms of levels of omega-3 fatty acids, mercury and other toxins, and in terms of their sustainability or ocean-friendly status. (more…)

Full Results of AIDS Vaccine Trial Confirm Modest Benefit

Health Vaccine

The full results of a landmark trial of an AIDS vaccine show that the shot did have limited success in protecting recipients from HIV.

But the study, published Tuesday in the New England Journal of Medicine, also suggests that this effect fades with time and may not work well for those at highest risk from HIV, such as people who engage in risky sexual practices or abuse intravenous drugs.

“Although our study provided preliminary evidence that an HIV vaccine regimen has the potential to prevent infection, it did not have the power to address two intriguing questions: vaccine efficacy may have decreased over the first year after vaccination, and vaccine efficacy may have been greater in persons at lower risk of infection,” wrote the researchers who tested the vaccine on more than 16,000 young adult volunteers in Thailand.

Scientists hope work with poison gas can be a lifesaver

Health News

A wiry, slightly hunched man presses in a few numbers, the electronic lock gives way with a beep and the group presses into the crowded laboratory, plastered with ominous warnings about toxins and biohazards.

Guiding the visitors at the Fred Hutchinson Cancer Research Center is Mark Roth, a 50-year-old biologist with a tall forehead, thinning red hair and a perpetual wry smile. He asks his assistant, Jennifer Blackwood, if the rat is ready. It is. She turns a dial, and the sealed enclosure starts to fill with poison gas — hydrogen sulfide. An ounce could kill dozens of people. (more…)

Nutrition for Skin Care

foodsSummer is the time to spice it up! Many spices contain strong antioxidants that help mitigate the damage caused by sun exposure. Spices are also rich in antioxidants: Antioxidants help prevent skin cancer by reducing inflammation, decreasing free radicals and preventing thymine dimmers.

Ginger has been shown to suppress colon cancer production in rats. Curry, which contains turmeric, is a very strong antioxidant which has been shown to decrease cancer production. Basil, cinnamon, clove, nutmeg, oregano and thyme have also been shown to have strong antioxidant activity.

Don’t be afraid to cook with spices for fear of decreasing their health benefits. One study looked at the effect of heat and cooking on the antioxidant properties of these spices and found that heating them to 180°C in the cooking process for 10 minutes did not affect the efficacy of antioxidant activity.

Flu Can Raise Chances of Heart Attack

fluPeople suffering from the flu may be at higher risk for having a heart attack, especially those with heart disease and diabetes, British researchers report.

Because both seasonal and the pandemic H1N1 swine flu are circulating this fall and winter, people at risk for heart attacks are urged to get a seasonal flu shot and an H1N1 flu shot, which may reduce the chance of getting the flu and thereby lower the risk for a heart attack, experts say.

“Influenza is most concerning because of its secondary complications,” said Dr. Marc Siegel, an associate professor of medicine at New York University School of Medicine in New York City.

“Most of the time with influenza, death or hospitalization isn’t because of the influenza, it’s because influenza puts you in a weakened state — it’s a stress on the system,” he said. “So, it is not surprising that you would have the increased risk of a myocardial infarction during or right after an influenza infection.”

In addition, the flu virus may have a negative effect directly on the heart, Siegel said. “Flu stresses and strains the system,” he added.

To determine the risk of heart attack among those with flu, a research team led by Andrew C. Hayward, a senior lecturer in infectious disease epidemiology at the UCL Centre for Infectious Disease Epidemiology in London, looked at 39 studies conducted between 1932 and 2008. (more…)

Taking showers ‘can make you ill’

ShowerShowering may be bad for your health, say US scientists, who have shown that dirty shower heads can deliver a face full of harmful bacteria. Tests revealed nearly a third of devices harbour significant levels of a bug that causes lung disease. Levels of Mycobacterium avium were 100 times higher than those found in typical household water supplies. M. avium forms a biofilm that clings to the inside of the shower head, reports the National Academy of Science.

In the Proceedings journal, the study authors say their findings might explain why there have been more cases of these lung infections in recent years, linked with people tending to take more showers and fewer baths. Water spurting from shower heads can distribute bacteria-filled droplets that suspend themselves in the air and can easily be inhaled into the deepest parts of the lungs, say the scientists from the University of Colorado at Boulder.

Potential threat

Lead researcher Professor Norman Pace, said: “If you are getting a face full of water when you first turn your shower on, that means you are probably getting a particularly high load of Mycobacterium avium, which may not be too healthy.” (more…)
