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.

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.

Mediterranean Diet With Extra Olive Oil May Prevent Breast Cancer

From my pantry...

From my larder…

A Mediterranean-style diet with supplemental extra-virgin olive oil seemed to reduce the incidence of breast cancer in a Spanish population. This is consistent with prior observational studies that link the Mediterranean diet with lower rates of breast and other cancers (colon, prostate, uterus, and melanoma).

The study population involved 4,000 women who were followed for five years. Thirty-five new cases of breast cancer occurred in this PREDIMED study sub-analysis.

The comparison diets were a reduced-fat diet and Mediterranean diet supplemented with mixed nuts.

This is a relatively small study, so results may not be entirely reliable.

Action Plan

If you’re a woman hoping to avoid breast cancer, consider the Mediterranean diet and be sure to eat plenty of extra-virgin olive oil. A good way to do this is to use home-made vinaigrettes.

Steve Parker, M.D.

PS: Even if you think Spaniards are jovial, you won’t find any in my books.

Which Cancers Does Exercise Prevent?

Needs a bit more hormetic stress

“Would you spot me, bro?”

I’ve always assumed that exercise reduces the risk of cancer, contributing to the well-established fact that folks who exercise live longer than others.

But a recent study found a positive association between exercise and two cancers: melanoma and prostate. “Positive association” means the more you exercise, the higher your risk of melanoma and prostate cancer (if you have a prostate).

The good news is that exercise was linked to lower risk of 13 other cancers.

Here’s a quote for the New York Times Well blog:

The researchers found a reduced risk of breast, lung and colon cancers, which had been reported in earlier research. But they also found a lower risk of tumors in the liver, esophagus, kidney, stomach, endometrium, blood, bone marrow, head and neck, rectum and bladder.

And the reductions in risk for any of these 13 cancers rose steeply as people exercised more. When the researchers compared the top 10 percent of exercisers, meaning those who spent the most time each week engaging in moderate or vigorous workouts, to the 10 percent who were the least active, the exercisers were as much as 20 percent less likely to develop most of the cancers in the study.

I’m surprised the protective effect of exercise against cancer wasn’t stronger.

Action Plan

So how much physical activity does it take to prevent cancer? And what type of exercise? We await further studies for specific answers.

I’m hedging my bets with a combination of aerobic and strength training two or three times a week.

Steve Parker, M.D.

PS: If you think cancer’s bad, read one of my books. Wait, that didn’t come out right.
