Exercise Beats Diet in Reducing Breast Cancer Risk

exercise

Women who lose weight by exercising and eating better may reduce their risk of breast cancer more than women who lose the same amount of weight through diet alone, according to a new study of postmenopausal women. 

Both exercising and eating better are thought to reduce women’s risk of breast cancer by decreasing body fat and levels of the sex hormones related tobreast cancer, according to the researchers. But the researchers investigated whether there is any additional benefit to exercising, beyond the effect of weight loss in reducing cancer risk.

The results suggest exercising has a stronger effect on breast cancers fueled by hormones, compared with dieting, and also offers additional benefits such as preserving lean body mass, said study researcher Anne Maria May, of the University Medical Center Utrecht, in the Netherlands. “Exercise is the preferred weight loss strategy to decrease breast cancer risk,” May said.

About 240 overweight women, ages 50 to 69, who didn’t regularly exercise participated in the study, presented here this week at the annual meeting of the American Society of Clinical Oncology (ASCO). The women’s goal was to lose 11 to 13 pounds (5 to 6 kilograms) over 16 weeks. About one-third of the women dieted, whereas another third enrolled in an endurance and strength training program, working out for four hours weekly. They also followed a slightly healthier diet, with a small decrease in their calorie intake. The rest of the participants didn’t change their habits, and served as controls for the study.

By the end of the study, women in both the exercising and dieting groups achieved their weight-loss goals. However, the exercising participants preserved their lean body mass (which includes muscles and bones), and reduced more of their body fat, compared with the dieting participants.

Moreover, blood tests showed the exercising participants reduced their levels of estrogen more than dieting participants did. (Many breast cancers need estrogen to grow.) Compared with women in the control group, the exercising women showed decreases in all types of estrogen in the body, whereas women in the diet group showed a decrease in only one type of estrogen, according to the study.

The researchers also found the exercising group showed a benefit in levels of other breast cancer related hormones, such as testosterone. It is likely that physical activity influences sex hormone levels mainly through reducing body fat, May said. The findings demonstrate the importance of exercising for postmenopausal women, she said. Previous studies have shown that lack of physical activity is one of the risk factors for developing breast cancer. Other than influencing the sex hormones, it is possible that exercising affects women’s cancer risk by reducing inflammation in the body, or decreasing levels of the hormone insulin, studies have suggested.

Pills vs. Diet For Erectile Dysfunction

NF-May15-Don’t-Pop-Pills-For-Erectile-Dysfunction.-Help-Your-Heart-Instead

Erectile dysfunction is the recurrent or persistent inability to attain and/or maintain an erection in order for satisfactory sexual performance. It is present in up to 30 million men in the U.S. and approximately 100 million men worldwide. The U.S. has less than 8% of the world’s population, yet up to 30% of the impotence? We’re #1!

But hey, we’ve got red, white, and blue pills like Viagra. The problem is that the pills just cover up the symptoms of vascular disease and don’t do anything for the underlying pathology. Erectile dysfunction and our #1 killer, coronary artery disease, are just two manifestations of the same disease: inflamed, clogged, and crippled arteries, regardless of which organ it affects (See Survival of the Firmest: Erectile Dysfunction and Death).

Atherosclerosis is considered a systemic disorder that uniformly affects all major blood vessels in the body. Hardening of the arteries can lead to softening of the penis because stiffened arteries can’t relax, open wide, and let the blood flow. Thus erectile dysfunction may just be the flaccid “tip of an iceberg” in terms of a systemic disorder. For two-thirds of men showing up to emergency rooms for the first time with crushing chest pain, their penis had been trying to warn them for years that something was wrong with their circulation.

Why does it hit the penis first? Because the penile arteries in the penis are half the size of the coronary artery in our heart. So the amount of plaque we wouldn’t even feel in the heart could clog half the penile artery, causing symptomatic restriction in blood flow. That’s why erectile dysfunction has been called “penile angina.” In fact, by measuring blood flow in a man’s penis we can predict the results of his cardiac stress test with an accuracy of 80%. Male sexual function is like a penile stress test, a “window into the hearts of men.”

Forty percent of men over age forty have erectile dysfunction. 40 over 40. Men with erection difficulties in their 40s have a 50-fold increased risk of having a cardiac event (like sudden death). I said before that various things increase heart disease risk by 20% or 30%. That’s nearly 5000%, leading the latest review to ask, “is there any risk greater?” That’s because it’s not so much a risk factor for atherosclerosis as atherosclerosis itself. A man “with erectile dysfunction (even if he doesn’t have cardiac symptoms) should be considered a cardiac patient until proven otherwise.”

Erectile dysfunction is considered to be a cardiac equivalent; it’s a marker of the coronary artery one likely already has. Thus, there’s more to treating ED than establishing an erect penis; it offers an opportunity for reducing cardiovascular risk. The reason even young men should care about their cholesterol is because itpredicts erectile dysfunction later in life, which in turn predicts heart attacks, strokes, and a shortened lifespan.

Exercise May Be the Most Effective Weapon Against Aging

senior couple

Keeping active may be the secret to staying young for both mice and men. Researchers from Canada’s McMaster University discovered that endurance exercise could halt the aging process in a group of mice, even though they were genetically engineered to age faster.

These furry creatures continued to exhibit the same youthful appearance as normal mice after engaging in a treadmill exercise routine over a period of several months. In addition, the exercise program prevented premature aging in almost every organ of the morphed mice. Details on the mighty mice can be found in the journal.

The results of the analysis indicate that not only can exercise help to prevent an early death, it can also delay the aging process. The researchers said that the exercise routine provided nearly 100 percent protection against graying fur, hair loss, brain and muscle atrophy, and more.
