Warning: A Hungry Spouse Is An Angry Spouse

April 16, 2014 8:11 am 0 comments

Anger cheese-classic-lmanagement training? How about a cheese sandwich? That, according to researchers at Ohio State University, may be all it takes to chill out an angry spouse. HealthDay reports that researchers at the school monitored the glucose levels of 107 middle-aged, married couples, who were also asked measure their anger levels by sticking in a voodoo doll representing their partner. The greater one’s anger, the more pins they were asked to use, stopping at 51. The same couples later faced off in a video game, where their hostility was expressed in the amount of violence they brought to the game. Yes, you are correct: when the researchers looked for a correlation between glucose readings and anger, they found it. People with lower blood glucose readings — those that fell under 98 milligrams per deciliter (mg/dL) — tended to be more aggressive toward their partners than those with evening readings over 121 mg/dL. The correlation hel even after researchers took into account how satisfied people said they were in their relationships, overall, and the sex of the partner who was being aggressive. Wait, there’s more: women tended to have higher daily pin-stick counts than men.

Get Used To It: Decline Begins At 24

By noStarCraft_II_-_Box_Artw, if researchers at Simon Fraser University are correct, most SportsGeezer readers have been getting a little slower and a little less sharp for decades. Yes, decades. In fact, based on an analysis of digital performance records of 3,305 StarCraft 2 players aged 16 to 44, researchers have concluded that our cognitive performance starts going downhill at age 24. The good news for those who are well past 24? “Older players, though slower, seem to compensate by employing simpler strategies and using the game’s interface more efficiently than younger players, enabling them to retain their skill, despite cognitive motor-speed loss.” Read more in Science Daily.

Overeating Sends “Good” Brown Fat Into “Death Spiral”

April 14, 2014 7:59 am 1 comment

Turns out that overeating Highest-Calorie-Foodshigh calorie foods is doubly troublesome: not only does it increase the production of “bad” white fat, it also leads to dysfunction in “good” brown fat cells, cells that, when functioning normally, actually burn calories. Futurity reports that the revelation comes from researchers at Boston University, who used experimental models to demonstrate that “over-nutrition” leads to a cellular signaling dysfunction that causes brown fat cells to lose neighboring blood vessels, depriving the cells of oxygen. This, in turn, causes the brown fat cells to lose their mitochondria, which leads to their inability to burn fatty acids and produce heat. Sounds bad, and it is: This collapse, the researchers report, can have far-reaching effects on the development of metabolic conditions, such as diabetes or cardiovascular disease. Or, as one researcher put it: “In addition to the expansion of white fat cells, our study shows that overeating causes brown fat cells to get locked into a death spiral.”

“Faking It” Fails. Yes, In Bed

April 11, 2014 7:40 am 1 comment

That’s rigstop-faking-it-story-500x280ht, the researchers at Waterloo University who studied the “sexual communication” of 84 couples are talking about “faking it” in the sack. Their conclusion? It’s a nice gesture, so to speak, but “on average, both men and women have fairly accurate and unbiased perceptions of their partners’ sexual satisfaction.” Lead author Erin Fallis said the researchers also found that “having good communication about sexual issues helped participants to understand their partners’ sexual satisfaction. However, even if sexual communication was lacking, a person could still be fairly accurate in gauging his or her partner’s sexual satisfaction if he or she was able to read emotions well.” Read more from the University of Waterloo.

Green Tomatoes Help Put On Muscle, May Help Lose Fat

April 10, 2014 11:07 am 0 comments

Yet another good thing about the color green. Green tomatoes, according to researchers at the University of Iowa, are loaded with a compound (tomatidine) that has a surprising ability to build muscle an6a01156faa621f970c0134856cfc3a970c-320wid protect against muscle atrophy. A university news release reports that researchers used a systems biology tool called the Connectivity Map to identify a small molecule compound that might be used to treat muscle atrophy. After zeroing in on tomatidine, they found that the compound generates changes in gene expression that are opposite to the changes that occur when people are affected by muscle atrophy. The researchers then tested tomatidine’s effects on skeletal muscle, and found that it stimulates growth of cultured muscle cells from humans. Next, the researchers added tomatidine to the diet of mice, and found that healthy mice supplemented with tomatidine grew bigger muscles, became stronger and could exercise longer.  Perhaps most importantly, they found that tomatidine prevented and treated muscle atrophy. Wait, there’s more: although mice fed tomatidine had larger muscles, their overall body weight didn’t change, because of a corresponding loss of fat. Get the picture?

Cut Yourself Some Slack. It’s Good For Your Health

April 9, 2014 7:57 am 1 comment

It’s possible that Relaxeverything that goes wrong is not your fault, but even if it is your fault, you might think about forgiving yourself. Why? Because self-compassion, otherwise known as cutting yourself some slack, has been found to be associated with lower levels of stress-induced inflammation. A Brandeis University news release reports that researchers at the school asked 41 people to rank their levels of self-compassion according to their agreement to statements such as, “I try to be understanding and patient toward aspects of my personality I do not like” and “I’m disapproving and judgmental about my own flaws and inadequacies.” The participants then took one stress test a day for two days and their levels of interleukin-6 (IL-6), an inflammatory agent linked to stress, were recorded before and after each test. After the first stress test, participants with higher self-compassion had significantly lower levels of IL-6. On the second day, the researchers found something unexpected. Those with low self-compassion had higher base levels of IL-6 before the test, suggesting that they may have been carrying the stress they experienced the day before. The bottom line: people with low self-compassion appear to be especially vulnerable to the adverse effects of stress.

Got Knee Arthritis? Drink Milk.

April 8, 2014 8:16 am 0 comments

Strange but true, or at least suggested by a recent study: milk may slow the progression of knee arthritis in women. HealthDaymilk reports that researchers at Brigham and Women’s Hospital in Boston have found that the more low-fat or fat-free milk women drank, the slower the progression of osteoarthritis of the knee. The same benefit was not true for yogurt and cheese, and there was no correlation between milk and arthritis found for men. The research, published in Arthritis Care & Research, involved 1,260 women and almost 900 men with knee arthritis. Scientists tracked the subjects diets and assessed the condition of their knees at the start of the study and again 12, 24, 36 and 48 months later. No, the researchers aren’t sure why milk slows arthritis. As they say, “more research is needed.”

Gallup Finds The Fittest Cities

And thimagese winner is…Boulder, Colorado. Gallup isn’t selling this survey as “fittest cities,” but it is saying that the winning cities are the least obese. Boulder, incidentally, comes in with an obesity rate of 12.4 percent, a few pounds below Naples, Florida, whose obesity rate, based on telephone interviews conducted as part of the Gallup-Healthways Well-Being Index survey Jan. 2-Dec. 29, 2012, and Jan. 2-Dec. 30, 2013, is 16.5.

Another Reason Not To Pee In the Pool

April 4, 2014 7:42 am 0 comments

OK, peeing in a swimming pool is gross, but if it’s insufficiently gross dissuade potential pee-ers, here’s another thing to think about. Researchers at Purdue Universityimages-1 have found that the uric acid in urine interacts with chlorine (in pools) in surprising ways, and can create hazardous “volatile disinfection byproducts,” including cyanogen chloride (CNCl) and trichloramine (NCl3). What are they? Cyanogen chloride is a toxic compound that affects many organs, including the lungs, heart and central nervous system by inhalation. Trichloramine has been associated with acute lung injury in accidental, occupational or recreational exposures to chlorine-based disinfectants. The Purdue findings were not a complete surprise. Researchers had known for years that certain airborne contaminants are created when chlorine reacts with sweat and urine in indoor swimming pools, but new findings show that uric acid from urine is definitely “an efficient precursor to the formation of CNCl and NCl3.

One-Two Punch For Body Fat: Green Tea + Exercise

April 3, 2014 7:33 am 3 comments

Exercise is a great way to lose weight, but exercise combined with green tea is even greater. A Penn State news releaseistock reports that researchers at the school found that high-fat-fed mice that exercised regularly and ingested green tea extract showed an average body mass reduction of 27.1 percent and an average abdominal fat mass reduction of 36.6 percent in just 16 weeks. Is that a lot? Well, mice that ingested green tea extract but did not exercise or those that exercised but were not given green tea extract experienced less significant changes in weight and health measurements. Wait, there’s more: the mice on the green-tea-extract-and-exercise regimen also experienced a 17 percent reduction in fasting blood glucose level, a 65 percent decrease in plasma insulin level and reduction in insulin resistance of 65 percent. Tea — Camellia sinensis — is rich in catechins, polyphenols that are natural antioxidents. The latest mouse study, incidentally, was unsurprising to scientists who had been working with people: A recent analysis of 11 human trials with green tea preparations reported a 1.31 kilogram average body weight loss in intervention groups compared to control groups.
