From an article on myths and facts in cancer prevention in The New York Times comes this interesting sidebar. Specifically, among things that have not been shown to prevent cancer are:
- Exercise
- Fruits and vegetables
- Losing weight
- Low-fat diet
So why are these so often recommended?
“I think it’s wishful thinking,” said Dr. Susan Love, a breast surgeon and president of the Dr. Susan Love Research Foundation. “We would like things to be more in our control. I think that’s part of it. And in the absence of anything else, what do we tell women about how to prevent breast cancer? We tell them to exercise and eat a good diet.”
Specifically regarding fatness, the main article notes that:
- Weight loss in adulthood has not been shown to reduce cases of cancer;
- The associations between being fat and getting cancer are correlations not causations, and often weak ones at that;
- “Studies that come up with such associations are likely to be published, even though often the associations turn out to be spurious.”*
* Can I just say I love that quote? It’s such a staid, scientific way of saying “linking fat people to bad things is popular, even though it often turns out to be garbage.”
