Could you post those studies, if you have them at hand? I know someone who has got increasingly cultish around their diet and I'm collecting things to show them how silly they are.
Here's a link explaining the research. And note, it was included as the source of the data I mentioned about, except the
omitted the bits that contradicted what they wanted to say
http://www.ahchealthenews.com/2015/03/19/pescatarian-diet-cuts-risk-of-colon-cancer/While a diet consisting of primarily fruits and vegetables is associated with a significantly lower risk of all colorectal cancer, adding fish to a diet reduces the risk of colon cancer even more. Those are the findings of a North American study involving 77,659 Seventh Day Adventist men and women who were followed for more than seven years. The study demonstrated that vegetarians, compared to non-vegetarians, had a 22 percent lower risk of developing all colorectal cancers – 19 percent lower risk for colon cancer specifically and 29 percent lower risk for rectal cancer.
The colorectal cancer risk was even lower – 43 percent — for vegetarians who also ate fish and 8 percent lower in semi-vegetarians. For vegans – those who consume no foods from animals, including milk, eggs and other dairy products — the risk for colorectal cancer was reduced by 16 percent.
Ok, this is the most objective outline of the data in question.
Vegan - 16% lower chance of these cancers.
Vegetarian - 22% lower chance of these cancers.
Notice here that being strictly vegan makes you sicker.Pescatarian -
43% lower chance of these cancers.
From this data, it's better for gut health to be vegetarian than vegan, and best to be a pescetarian.
Also, Yoink as to why this is important:
Colorectal cancer is the second leading cause of death in the United States.
It's the second biggest killer in the USA, so medical concern about how to minimize it is justified.
Basically, articles like the previous one I posted took this data and presented it as "don't eat any meat at all" removing the context:
https://www.upi.com/Health_News/2018/09/11/Going-vegetarian-may-lower-colon-cancer-risk/1611536711171/And a study of 77,000 adults published in JAMA Internal Medicine found that you can also lower your risk of this cancer by making changes in your diet right now, whatever your age.
...
On average, eating vegetarian may lower colon cancer risk by 19 percent and rectal cancer by 29 percent compared to non-vegetarians -- people who eat meat at least once a week. Besides eating less meat, the vegetarians in the study ate fewer sweets, snacks, refined grains and high-calorie beverages and more fruits, vegetables, whole grains, beans and nuts.
So, in other words it's clearly from the same study data as the other one, but they deliberately excluded the "fish eaters are healthier" point and the "vegans are less healthy" point, because they're pushing a particular agenda, and inconvenient facts needed to be jettisoned. Notably however, they do make it clear here that
no effort at all was taken to control the data for other eating habits. People who make
conscious decisions about what to eat are healthier, and this confounds the data unless you control for it. "meat eater" might include people who eat pizza every night and drink soda every day in the data, so it's not sufficient to just group people based on an ideology then just say "look the meat eaters are sicker - don't eat any meat". The data wasn't fine-grained enough to say that.
That's why you also have other studies showing vegetarians in fact get more of these cancers when different controls are in place:
