Exercise Cuts Your Risk of Cancer by Up to 25%

Exercise is a fountain of youth available to every one

From UPI:

In findings published Thursday in the Journal of Clinical Oncology, researchers at the National Cancer Institute, the American Cancer Society, and the Harvard T.H. Chan School of Public Health report that people who engaged in physical activity as recommended by the National Institutes of Health were able to reduce their risk for seven different types of cancer by as much as 25 percent.

This included common—and deadly—forms of the disease like colon and breast cancers, as well as endometrial cancer, kidney cancer, myeloma, liver cancer, and non-Hodgkin lymphoma.

Updated federal guidelines for physical activity recommend that people should aim for two and a half to five hours per week of moderate-intensity activity or 75 to 150 minutes per week of “vigorous activity.”

You can also reduce your risk of cancer by eating the traditional Mediterranean diet smoking, by not drinking excessive alcohol, and by not smoking.

Dr David Ludwig Calls for More Research on Ketogenic Diets

Sous vide chicken and sautéed sugar snap peas. This meal is part of a ketogenic diet.

From The Journal of Nutrition:

Recently, ketogenic diets have received substantial attention from the general public and nutrition research community. These very-low-carbohydrate diets, with fat comprising >70% of calories, have been dismissed as fads. However, they have a long history in clinical medicine and human evolution. Ketogenic diets appear to be more effective than low-fat diets for treatment of obesity and diabetes. In addition to the reductions in blood glucose and insulin achievable through carbohydrate restriction, chronic ketosis might confer unique metabolic benefits of relevance to cancer, neurodegenerative conditions, and other diseases associated with insulin resistance. Based on available evidence, a well-formulated ketogenic diet does not appear to have major safety concerns for the general public and can be considered a first-line approach for obesity and diabetes. High-quality clinical trials of ketogenic diets will be needed to assess important questions about their long-term effects and full potential in clinical medicine.

Red and Processed Meats Not So Deadly After All?

From New York Times:

Public health officials for years have urged Americans to limit consumption of red meat and processed meats because of concerns that these foods are linked to heart disease, cancer and other ills.

But on Monday, in a remarkable turnabout, an international collaboration of researchers produced a series of analyses concluding that the advice, a bedrock of almost all dietary guidelines, is not backed by good scientific evidence.

Whew…What a relief! Dodged that bullet.

Do You Really Need That PPI?

“I don’t mind dying. I just don’t want to be there when it happens.” –Woody Allen

Proton pump inhibitors (PPIs) are widely used in the U.S. to treat or prevent heartburn and ulcers. For example, omeprazole is the 6th most prescribed drug in the U.S. according to one source. PPIs reduce acid production by the stomach. Doesn’t it make sense that God or Nature gave us that stomach acid for a reason? Like to kill germs or aid the digestive process?

From the British Medical Journal:

Taking PPIs is associated with a small excess of cause specific mortality including death due to cardiovascular disease, chronic kidney disease, and upper gastrointestinal cancer. The burden was also observed in patients without an indication for PPI use. Heightened vigilance in the use of PPI may be warranted.

If you suffer from frequent heatburn, try cutting down on carbohydrates.

Women With Type 2 Diabetes and Obesity-Related Cancer Risk

In general, women are a bit less likely to get cancer than men. But having type 2 diabetes and obesity negates that advantage.

“If you’re a woman with type 2 diabetes, you may be interested in a recent study done regarding obesitiy-related cancer risk. The CDC says that 40 percent of cancers in the U.S. are associated with being overweight or obese. These include cancers of the breast, gallbladder, liver, thyroid, kidneys, uterus, pancreas, upper stomach, colon and rectum, ovaries, multiple myelomas, adenocarcinoma of the esophagus, and meningiomas.

When it comes to diabetes and obesity, the duo “seem to be partly overlapping risk factors for the development of obesity-related cancer”. This especially includes breast, prostate, and colorectal cancer in those with type 2 diabetes, according to study authors.”

Regarding prostate cancer, I’ve seen one study that concluded diabetics are less likely to get prostate cancer.

Can Diet and Exercise Prevent Cancer?

You need to worry about cancer because you have a roughly four in 10 chance of coming down with invasive cancer. (Skin cancers like squamous cell and basal cell are quite common, but rarely invasive.)

Dr. David Gorski is a breast cancer surgeon. He’s looked at the scientific literature on the linkage between diet and exercises, and the risk of developing cancer.

Here’s his conclusion from a review at Science-Based Medicine:

“You can reduce your risk of cancer by staying active and exercising, eating a healthy diet with a lot of plant-based foods and minimizing intake of processed meats, limiting alcohol consumption (although I think the WCRF/AICR guidelines go a bit too far in saying that you shouldn’t drink at all if possible), and maintaining a healthy weight. (Of course, if you stay active and eat a healthy diet, maintaining a healthy weight will probably not be a problem.) Conceptually, it’s easy to do. In practice, as I’m discovering, it’s anything but easy.”

The Mediterranean diet seems to protect against cancer.

Cancel Alcohol’s Carcinogenic Effect With Exercise

It was just a few months ago we learned that you’ll die of cancer if you tipple. Well, a new study says you can counteract the carcinogenic alcohol with adequate physical activity.

A story at CNN tells us how much exercise it takes :

“Specifically, they looked at the impact of the recommended amount of weekly exercise for adults, which is 150 minutes of moderate aerobic activity. That includes brisk walking, swimming and mowing the lawn, according to the US Department of Health and Human Services. HHS also advises strength training for all major muscle groups at least twice a week.”

Source: Exercise can cancel out the booze, says study – CNN.com

The rule of thumb on how much alcohol is relatively safe to drink is 7 typical drinks a week for women, and 14 for men.

Also remember that even one or two drinks under the right circumstances can have devastating consequences.

Steve Parker, M.D.

PS: All of my books have extensive recommendations on getting started with exercise, even if you’re a 300-lb couch potato.
