How are they controlling for deaths from other causes, e.g. cardiovascular disease? If you're not dead from some other cause then you're going to be more likely to die from cancer, even if vegetables are actually conferring a significant anti-cancer benefit.
I see that they are using people years to track followup, but I'm not clear from the methodology whether this is enough to fully control for this issue.
- wapz 10y agoAre you stating that death from cardiovascular disease would be higher (or lower) from people who don't eat fruits/vegetables which means they have a "lower" chance of getting cancer? My guess would be that they didn't take that into account and that the deaths from cardiovascular (or other diseases) would be ignored in the assumption they are "similar" between the two sides.
- Alex3917 10y agoTo rephrase, I'm suggesting that eating vegetables may lower the risk of cardiovascular disease. If you don't die from cardiovascular disease, then it's more likely that cancer is the thing you do die from. So even if eating vegetables reduces your risk of cancer, you could actually be more likely to die from cancer if you eat vegetables.
- wapz 10y agoAhh thanks for the clarification. Your logic makes a lot of sense. I believe there was a study that showed pesticides may cause cancer (it was probably done in mice or something) from a long time ago but this is just the top of my head so I don't know if there's any relation to fruit/veggie consumption.
