Why Healthy Fast-Food Menu Options Can Backfire

Image
Adding a healthy option can actually drive people to make even worse choices, thanks to a mind-blowing glitch of human psychology. In 2017, and to much fanfare, menu labeling for calorie counts began to be mandated in national chain restaurants. Consumers should have the information needed to make healthy food choices outside the home, right? It makes sense that caloric information on menus will help people limit their food intake to stay within their daily energy needs. But it didn’t work. It turns out calorie labels are not effective, shaving off an average of eight insignificant calories per meal. You could have totally predicted that. Why? Just as one might divine the value of front-of-pack traffic light labeling from the ferocity of the industry response against it, one could probably gauge the futility of calorie labeling by the ease with which some regulations have been passed. McDonald’s voluntarily started publishing calorie information nationally back in 2012 after a...

Which Beans Best Block the Spread of Cancer?

Image
Which legumes are best at inhibiting the matrix metalloproteinase enzymes that allow cancer to become invasive? Although we’re spending billions of dollars on fancy new types of chemotherapy, the overflowing sink that is cancer treatment is expected to rise by about 70% over the next two decades because drugs are being used to merely mop up the mess rather than turn off the faucet. You can’t really give drugs to people to prevent cancer because of the side effects and cost, but there is said to be “overwhelming…evidence that the dietary bioactive compounds found in whole plant-based foods have significant anticancer and chemopreventive [cancer-preventing] properties.” I’ve previously talked about the impact of diet and nutrition on the 10 hallmarks of cancer. The bottom line is that evidence points to a diet that includes minimal animal products and, perhaps more importantly, maximal plant foods. Some foods that seem to be especially beneficial include fruits (especially berries), ...

A Persistent Pesticide Is Linked to Alzheimer’s Risk

Image
How can we avoid the breakdown products of pesticides that may increase the risk of Alzheimer’s disease as much as if you carried APOE e4, the so-called Alzheimer’s gene? Although there is a growing list of Alzheimer’s disease susceptibility genes, those genes account for less than half of all Alzheimer’s cases. Here is the “single most compelling” piece of data on the potential control we have over the disease: When it comes to identical twins with the exact same genes, if one gets Alzheimer’s, the other usually does not. So, we have to think about all the other contributing factors beyond just genetics. There’s a list of chlorinated pesticides, including DDE (a metabolite of DDT), that the U.S. Environmental Protection Agency has classified as probable human carcinogens. But in a study—which I’ve mentioned in a video on pesticides and cancer—blood levels of DDE and other pesticides were associated not with increased cancer mortality, but increased risk of other-cause mortality. ...

How Big Is the Cancer Risk from Processed Meat?

Image
I quantify the risks of colon and rectal cancers from eating bacon, ham, hot dogs, sausage, and lunch meat. In 2018, arguably the most prestigious cancer research institution in the world, the International Agency for Research on Cancer (IARC), part of the World Health Organization, published its report on processed meat, concluding that foods like bacon, ham, hot dogs, lunch meat, and sausage are cancer-causing, classifying processed meat as a Group 1 carcinogen. “These findings,” concluded the director of the agency, “further support current public health recommendations to limit intake of meat.” Critics questioned putting processed meat in the same carcinogenic classification as asbestos and tobacco. Or, as a pesticide company roughly put it, how can eating processed meat be in the same category as mustard gas? As I discuss in my video How Much Cancer Does Processed Meat Cause? , the classifications only relate to the strength of evidence that the agent causes cancer or not, ...

The Backlash to IARC’s Report that Meat Probably Causes Cancer

Image
How did the meat industry, government, and cancer organizations respond to the confirmation that processed meat, like bacon, ham, hot dogs, and lunch meat, causes cancer? “It is rare, in the history of nations, that one finds good reasons to render homage to the generosity and altruism of governments and those in power: the birth of the International Agency for Research on Cancer [IARC] presents one of those rare occasions.” It all started with a single letter from a grieving husband, relating his wife’s suffering after being diagnosed with cancer, cascading into an open letter calling for governments to devote half of 1% of their military budgets to fight for life by attacking one of the greatest plagues that weighs on humanity. And 18 months later, the IARC was born in the World Health Organization. What was its overarching motive? Cancer prevention. As I discuss in my video, IARC: Processed Meat Like Bacon Causes Cancer , the IARC is best known for its monographs, book-sized...

Is Personalized Genetic Testing Worth It?

Image
Overrated “precision medicine” may just be serving vested interests, and consumer DNA testing can be useless—or even worse. Today, you can get your DNA sequenced—the letters of your entire genetic code spelled out—for about a thousand dollars, a bargain compared to the $100 million or so it cost 20 years ago. And for around a hundred dollars, you can get partial DNA sequencing. Direct-to-consumer genetic testing is “only a click away,” like 23andMe, for “ancestry, health, love…and more.” Unfortunately, many tests that are available today haven’t been validated properly. And, as a result, the buyer may be buying something “that is ultimately useless.” Or, results may just be just flat-out wrong. There is growing public demand for direct-to-consumer genetic tests, but when put to the test, researchers found an “alarmingly high false-positive rate.” Test results indicated that people carried a high-risk gene, but it simply wasn’t true. And this happened 40% of the time, especially wi...

Are Nuts and Peanut Butter Linked to a Longer Life?

Image
Why are nuts associated with decreased mortality, but not peanut butter? According to the largest study of risk factors for death in human history, a poor diet causes more deaths than anything. Cigarettes only kill about 8 million people a year, whereas humanity’s diet kills millions more, as you can see below and at 0:20 in my video Do the Health Benefits of Peanut Butter Include Longevity? . What are the worst aspects of our diet? Processed meat? Twinkies? Soda? No, the five deadliest things about our diet are : not enough fruit, not enough whole grains, not enough vegetables, too much salt, and not enough nuts and seeds, as shown here and at 0:42 in my video . Nuts should come as no surprise since interventional trials have shown that eating nuts improves artery function, and arterial diseases like heart disease are among our leading killers. But that’s not all nuts can do. They may also improve blood sugar control, lower cholesterol, suppress inflammation, reduce oxidative st...
