Study shows daycare may protect kids from leukemia

Study shows daycare may protect kids from leukemia - Yahoo! News/Reuters
2008.04.28
"...children who attended daycare or playgroups have a 30 percent lower risk of developing the most common form of childhood leukemia compared to those who do not...the review of 14 studies showed children who started daycare at age 1 or 2 had the most protection...The study did not identify how social contact may guard against leukemia but it adds to evidence that children exposed to infections early in life somehow gain protection against the rare disease, Buffler said. Scientists believe two things must happen for most types of childhood cancer. The first is some kind of genetic mutation that a child is born with followed by a trigger in childhood such as an infection that results in the disease, she added."This is just more evidence pointing to the role that some type of infection early in life could stimulate the immune system,"..."

Vitamins A, C and E are 'a waste of time and may even shorten your life

Vitamins A, C and E are 'a waste of time and may even shorten your life'| News | This is London
2008.04.16
"Vitamins taken by around a third of the population do not extend life and may even cause premature death, according to a respected group of international scientists...After reviewing 67 studies involving more than 230,000 men and women, the experts say there is no convincing evidence that taking supplements of the antioxidant vitamins A, C and E can make you healthier...Vitamin A was linked to a 16 per cent increase in mortality, beta-carotene - the pigment found in carrots, tomatoes and broccoli which the body converts into vitamin A - to a 7 per cent increase and vitamin E to a 4 per cent increase. However, there was no significant detrimental effect caused by vitamin C..."

This isn't surprising and in line with other meta studies. By now the message is clear, try and get these vitamins through fruit and vegetables. If one is looking to increase longevity a bit beyond exercise and diet then compounds that increase endogenous antioxidants are an entirely different matter. There are plenty of such compounds - a few are: bacopa, curcumin, cocoa, milk thistle, ashwagandha, alpha lipoic acid, tea extracts, resveratrol and so on.

2008.04.11
"WASHINGTON (Reuters) -
Trans-fats, which are being phased out of food because they clog arteries, may raise the risk of
getting breast cancer, European researchers reported on Friday...women with the highest blood levels of trans-fats had about twice the risk of breast cancer compared to women with the lowest levels...Women with higher levels of omega-3 fatty acids, being studied for their potential benefits to health, were not any less likely to have breast cancer, the researchers found...Obese women are more likely to develop breast cancer, among other types of cancer, and high-fat diets are also linked with breast cancer."

Too little childhood sleep tied to later health problems

Too little childhood sleep tied to later problems - Yahoo! News: (Reuters) -
2008.04.07
"Getting too little sleep doubles a young child's risk of being overweight and raises the chances
of later anxiety and depression...In a study involving 915 children in
Massachusetts, they found that those who slept less than 12 hours a day in the first two years of life were twice as likely to be overweight at age 3 than children who slept longer...Another team of researchers led by Alice Gregory of the University of London examined the long-term emotional fallout from too little sleep in childhood. They gathered sleep data on 2,076 Dutch children ages 4 to 16, and then questioned them as adults years later about various emotional and behavioral symptoms...The children who slept less than others reported more anxiety, depression and aggressive behavior as adults..."

Green Tea Helps Beat Superbugs, Study Suggests

Green Tea Helps Beat Superbugs, Study Suggests - ScienceDaily
2008.04.01
"The pharmacy researchers have shown that drinking green tea helps the action of important antibiotics in their fight against resistant superbugs, making them up to three times more effective..."In every single case green tea enhanced the bacteria-killing activity of the antibiotics. For example the killing effect of chloramphenicol was 99.99% better when taken with green tea than when taken on its own in some circumstances."...Green tea also made 20% of drug-resistant bacteria susceptible to one of the cephalosporin antibiotics. These are important antibiotics that new drug resistant strains of bacteria have evolved to resist...The results surprised the researchers, showing that in almost every case and for all types of antibiotics tested, drinking green tea at the same time as taking the medicines seemed to reduce the bacteria's drug resistance, even in superbug strains, and increase the action of the antibiotics. In some cases, even a low concentration of green tea was effective..."
