Fitness Cuts (Some) Cancer Risk In Half

March 27, 2015 7:33 am 0 comments

First, the numbers: 13,949 men were given a treadmill test to determine cardiorespiratory fitness (CRF). During an average 6.5 years, 1,310 of them were diagnosed with prostate cancer, 200 with lung cancer and 181 men with coloimagesrectal cancer. Researchers found that men with a high CRF in midlife had a 55 percent lower risk of lung cancer and a 44 percent lower risk of colorectal cancer compared to men with low CRF. And now the bad news: the same association was not seen between midlife CRF and prostate cancer. Why? Science Daily reports that the researchers don’t really know, but they speculate men with high CRF may be more prone to undergo preventive screenings and therefore have a greater opportunity to be diagnosed with prostate cancer. Wait, there’s more: The study also found that high CRF in midlife was associated with a 32 percent lower risk for cancer death among men who developed lung, colorectal or prostate cancer at Medicare age compared with men with low CRF.

Don’t Get Angry: It’s Bad For Your Health

March 26, 2015 9:05 am 0 comments

How bad, exactly, isimages-1 anger for your health? Let this article in the Wall Street Journal count the ways. The journal reports that anger releases adrenaline and cortisol, which can trigger an increase in heart rate, blood pressure and sugar metabolism. That’s great if you’re being attacked by a saber-toothed tiger, but it’s not so great when you’re sitting in traffic. Long term health effects can include damage to the heart, and increased blood pressure and blood flow can damage the lining of arteries. Want studies? Here you go: A study of 300 heart attack patients published in March in the European Heart Journal: Acute Cardiovascular Care found that those who had experienced intense anger had an 8.5 times greater risk of heart attack in the two hours after the outburst than they would normally. Yes 8.5. And this: a review of nine previously conducted studies on anger and cardiovascular problems found a higher rate of problems including strokes, heart attacks and arrhythmia, or irregular heartbeat, in the two hours following an outburst of anger. Read more in the Wall Street Journal, and relax.

To Live Longer, Eat Whole Grains

March 25, 2015 7:43 am 0 comments

imagesReaders who would prefer a longer life should note well: Researchers at Harvard Medical School tracked about 370,000 people -all aged from 50 to 71- from the mid-1990s, when they took surveys, through the year 2009. The envelope please… the researchers found that those who ate the most fiber were 17 percent less likely to die during the study period than those who ate the least. But wait, the risk of death during the study was pretty low to begin with; only about 12 percent (just over 46,000) of the people died during the study period. HealthDay reports on a few other things that might influence the findings: Those who ate the most fiber were more likely to be educated, less likely to be obese and less likely to smoke than those who ate the least. The whole grain eaters also ate much less red meat. OK, how many whole grains does one have to eat to be a whole grain eater?  The researchers defined heavy eaters of whole grains — those with the greatest life span benefits — as those who ate 34 grams of whole grains for every 1,000 calories they consumed per day. That’s the  equivalent of five slices of whole wheat bread or 5 cups of whole-grain breakfast cereal.

More Exercise = Better Sex

March 24, 2015 7:54 am 0 comments

Let’s gobc-a+case+for+romance right to the numbers: How much exercise does a man have to do to have noticeably better sex? Answer: Two hours of strenuous exercise, 3.5 hours of moderate exercise, or six hours of light exercise a week. For those readers interested in more information, there’s this: HealthDay reports that researchers at the Cedars-Sinai Center for Integrated Research in Cancer and Lifestyle in Los Angeles surveyed nearly 300 men about  their physical activity levels and their ability to have erections and orgasms, the quality and frequency of erections, and their overall sexual function. The envelope please…. the researchers found that better sex was reported by those who engaged in the equivalent of two hours of strenuous exercise, 3.5 hours of moderate exercise, or six hours of light exercise a week. Wait, there’s more: the men who exercised less had lower sexual function scores.

Vitamin D May Slow Some Prostate Cancer

March 23, 2015 9:02 am 0 comments

imgresOver the years, vitamin D has been hailed, and often unhailed, as a cure for several unpleasant conditions. Now comes research from the Medical University of South Carolina suggesting that it can slow the progression of some non-aggressive prostate cancers. Science Daily reports that researchers at the school conducted a randomized, controlled clinical trial, which assigned 37 men undergoing elective prostatectomies either to a group that received 4,000 U of vitamin D per day, or to a placebo group that didn’t receive vitamin D. The men’s prostate glands were removed and examined 60 days later. The envelope please… Preliminary results show that many of the men who received vitamin D showed improvements in their prostate tumors, while the tumors in the placebo group either stayed the same or got worse. Note well: all of the men in the study had low-grade prostate cancers, with Gleason scores of 6 and below. There is no evidence that vitamin D can slow aggressive prostate cancer.

Drinking Milk May Stave Off Alzheimer’s

March 20, 2015 7:46 am 2 comments

Drinking wine may beimgres good for your heart, but for brain health, you may need another beverage: milk. Researchers at the University of Kansas Medical Center who asked 60 people about their milk consumption and took scans of their brains are convinced that people who drink a lot of milk have higher levels of glutathione in their brains. Why do we care? Because glutathione could help stave off oxidative stress and the resulting damage caused by reactive chemical compounds produced during the normal metabolic process in the brain. And why do we care about that? Because oxidative stress is associated with a several unpleasant diseases and conditions, including Alzheimer’s disease and Parkinson’s disease. Got milk?

For Women, More Sleep = More Sex

March 19, 2015 7:52 am 0 comments

At least two good images-2things often happen in bed, and now researchers at the University of Michigan Sleep and Circadian Research Laboratory believe they are related. HealthDay reports that scientists at the sleep lab surveyed 171 college-age women, who kept diaries of their sleep for 14 consecutive days and reported whether they engaged in sexual activity the next day. The envelope please….yes, longer sleep time was linked with greater sexual desire the next day. Wait, there’s more: women with longer average sleep duration said they had better genital arousal than women with shorter sleep time. How long is long? On average, the women reported sleeping 7 hours, 22 minutes.

The Diet Soda/Fat Belly Question

March 18, 2015 7:52 am 0 comments

imgresDoes drinking diet soda make us fat, or do fat people drink more diet soda than thinner people; that is the question. And the answer is……nobody knows. What researchers do know is that there is an association between the consumption of noncaloric sodas and a wider waist circumference. HealthDay reports that researchers studied the findings from a previous study of more than 700 white and Latino people, all of whom were 65 or older when they entered the study. After nine years, the researchers found, the waistlines of people who never drank diet sodas increased by 0.8 inches; occasional diet soda drinkers’ abdominal girth grew by 1.8 inches; and those who drank diet soda every day expanded their waistlines expanded by more than 3 inches. Impressive.

Cancer Fatigue? Walk It Off

March 17, 2015 8:51 am 1 comment

Can walking, yes just walking, really reduce cancer-related fatigue? Researchers at McGill University think so. A McGill U news releasecancer-fatigue reports on a pilot study that assigned eight-week-long personalized walking exercises to 26 people with advanced cancer. Participants who walked less than 5,000 steps per day were told to increase their daily steps by 10 percent every week, if fatigue remained the same or improved, the number of steps was to be increased.  If the individual’s fatigue level worsened, no increase; if fatigue levels worsened for two weeks in a row, the steps were to be decreased by the same amount as the increase. The envelope please….“We found the effect on fatigue was quite strong,” the researchers wrote. “Walking promoted better physical function, and enhanced overall well-being. Interestingly, shorter bouts of low intensity exercise and shorter duration overall had a promising effect on cancer related fatigue. This is compatible with the theory of emphasizing the need to build, not deplete, resources. While our small study showed promise, more testing is needed in a full study.”

Energy Drinks Boost Blood Pressure

March 16, 2015 8:18 am 1 comment

Energy may be good thing, bimgresut energy at the price of increased blood pressure? You decide. Science Daily reports that researchers at the Mayo Clinic gave a can of a commercially available energy drink or a placebo drink to 25 healthy young adults, age 19 to 40, then measured changes in heart rate and blood pressure. Blood pressure and heart rate were recorded before and 30 minutes after energy drink/placebo drink consumption, and were also compared between people who didn’t regularly drink caffeinated beverages and regular caffeine users, defined as those who had at least one cup of coffee a day. The envelope please…The researchers found a marked rise in blood pressure after consuming the energy drink as compared to the placebo, and they found that the effect was most dramatic in people who did not typically consume much caffeine. In fact, the blood pressure increase was more than doubled in caffeine naïve adults after consuming the energy drink vs. placebo.
