Study finds that fast walking can reduce lung cancer risk by 50%: A simple health indicator for cancer preventionPerhaps. Or maybe, people with healthier, more efficient lungs are able to walk faster without breathing heavier. In that case, breathing less might reduce the inhaled carcinogens, reducing the risk of lung cancer.
Looking at the actual research, the conclusions are carefully worded to avoid this sort of reporting.
Faster walking speed, whether self-reported or measured, is associated with a reduced risk of cancer development. This association appears to be partially mediated by lower inflammation and improved lipid profiles.

Or maybe, people who have healthier lungs don’t need to breathe as much to efficiently exchange oxygen for CO2. So maybe breathing less protects against lung cancer by inhaling fewer carcinogens.
There are simply too many confounding variables to control for all of them. Research like this is important, and it’s not the researchers’ fault. Notice how the conclusions are carefully worded to specifically avoid exactly this sort of news article.

Study finds that fast walking can reduce lung cancer risk by 50%: A simple health indicator for cancer preventionA research team in the Department of Pharmacology and Pharmacy at the LKS Faculty of Medicine of the University of Hong Kong (HKUMed), has conducted a pioneering study that found an association between walking speed and cancer risk. The researchers found that individuals who walk faster have a markedly lower overall risk of developing cancer, particularly lung cancer. This association was consistent regardless of whether walking speed was self-reported or objectively measured.
As always, correlation =|= causation. Walking speed is almost certainly linked to like 15 other good health indicators. Exercise is good for you, and you should do it. But these results do not support the recommendation that fast walking will reduce your chances of lung cancer. These results say that if you already walk fast that you probably have a lower chance of lung cancer. Maybe it is the healthier lungs that allow you to walk faster? Maybe it’s a genetic component that makes you walk faster AND reduces your chances of lung cancer. Maybe they fucked up the sample and all of their slow walkers lived downwind of an asbestos plant.
Again, exercise is good for you. Exercise as much as you can. Cannot stress that enough. The health value of exercise is unquestionable and universal, and a lack of exercise is bad for you in every way. Bad science is bad for everyone, though.

A lesson so many need to learnI never understood people who hate on the RAW. Like, it’s an open concept. Make it your own. Any changes can be done at the first session, and if you have an adjustment that’s better, everyone will agree and it will catch on.

Smoke pointsIf you’re cooking fresh oil over low heat, these smoke points are probably accurate. If you are using a high heat, the oil may start to smoke before the thermometer reads those temps. That’s what it means by “based on… cooking temperature.”
You’re right that the disclaimer is intended to absolve them of any responsibility, though.
