We do know, all the evidence points in the direction that the western diet, high in animal products and processed foods is the number explanation for the rampant increase of cancer, diabetes and heart disease in the west.
This argument is old: we don't know because the perfect experiment has not been conducted and never will and because the studies that we have don't say what we want to hear.
If the news is bad, question the source and keep doing the same thing. This was what was done for decades with tobacco, for decades the validity of the argument that it causes cancer was questioned.
Here we are in 2019 and still 15% of adults smoke in the US. And still, the perfect experiment was never done and never will.
Take any population that is healthy, they move to the west and develop these illnesses. The places in the world that have the best health are the ones that eat fewer animal products.
The Inuit that eat only meat and fish have rampant arteriosclerosis.
People on the paleo diet have been found to have much higher levels of a biomarker linked to heart disease than people on a normal diet, for which cancer rates are increasing - https://www.sbs.com.au/news/study-links-paleo-diet-to-heart-...
When a whole country stopped eating animal products for a year (during WW one) their health as a population massively increased.
The list goes on and on, we have epidemiological studies, we have population studies, we know some of the mechanisms through which cancer is developed, we know that a plant-based diet reverses heart disease.
But we still prefer to keep saying that we just don't know, because we don't like the news.
