Millions of American kids are allergic to peanuts… and for some, being exposed to peanuts can be fatal. But a study in The New England Journal of Medicine shows that gradually ramping up exposure to tiny amounts of peanut protein every day for a year can make it safer. At the start of the study, none of the nearly 500 four-to-17 year old subjects could tolerate eating even one-tenth of a peanut. After a year of treatment, two-thirds of them could eat at least two whole peanuts… so an accidental exposure was no longer life threatening.
More American children are living in three-generation households than ever before. A study in the journal Demography shows that nearly 10 percent of children, or about seven million kids, are living with both a parent and grandparent. That’s nearly double the figures from roughly 20 years ago. Multi-generational homes are more common among the economically disadvantaged… but researchers say the fastest growing group now includes moms who are older, wealthier, more educated. And single.
If you thought volunteering to help out a co-worker is a good thing… think again. A study in The Journal of Applied Psychology shows that it’s better to wait to be asked before you help. Scientists say helpers who jump in without being asked often don’t have a good handle on what they’re doing, so they don’t get much gratitude for it… and the person being helped starts feeling incompetent. Better to stick to your own business, researchers say… until you’re asked.
And finally… if you can’t get enough coffee, it may be all in your genes. A study in the journal Scientific Reports finds that people who are genetic super-tasters for the bitter taste of caffeine are 20 percent more likely than average to drink at least four cups of coffee per day.
Some people are more likely than others to become persistent opioid users after surgery, and a new report from “Choices Matter” finds that millennial women are at greatest risk. Researchers say the number of women age 18 to 34 who become persistent opioid users six months after surgery rose by 17 percent last year alone. Forty percent more women than men continue using opioid painkillers long after surgery, and while 12 percent of patients overall become addicted or dependent on them after surgery, that number is 18 percent among millennials.
Over the last decade or so, a number of studies have come out suggesting that a glass of wine per day is good for your heart. But a new study finds that the risks of drinking far outweigh the benefits. In fact, researchers say consuming just one drink per day, every day increases the risk of premature death by 20 percent. The study in the journal Alcoholism: Clinical and Experimental Research explains that daily drinking increases cancer risk so much that it overshadows any heart benefit.
A person’s mix of intestinal bacteria can mean the difference between being thin or obese. Now a new study shows that the bacteria in an infant’s mouth can predict obesity. The study in the journal Scientific Reports finds that a child’s oral bacteria at age two can predict obesity two years later. Researchers hope the finding may lead to preventive steps for children who are found to be at risk.
Lung cancer deaths in California are 28 percent lower than the rest of the country, and that gap is increasing by almost a percentage point per year. What are they doing right? A new study in the journal Cancer Prevention Research gives credit to the state’s aggressive anti-smoking campaign. Researchers say the campaign has resulted in a 39 percent lower rate of people who start smoking compared to the U.S. as a whole, a 30 percent lower consumption of cigarettes among those who do smoke, and a 24 percent higher early quit rate.
And finally… if you want to avoid getting sick this flu season, science has proven a way to increase the odds—turn on your tv. A study in the journal BMC Infectious Disease shows that people who watch more tv get sick with the flu less often. The reason is pretty obvious. Those people are staying home and have a lot less chance to catch a flu virus from someone else.
