PORÓWNANIE WPŁYWU DIETY MIĘSNEJ I WEGETARIAŃSKIEJ NA WYSTĘPOWANIE RAKA JELITA GRUBEGO

Dear Editor,
We recently read an interesting article by Yad Di et al. [1] describing the impact of a meat-based diet on gastrointestinal cancers. We were particularly intrigued by its implications for colorectal cancer. Meat-based diets continue to be one of the most commonly adopted eating patterns. In our opinion, this article addresses an important issue, and the analysis of the relationship between colorectal cancer and meat consumption may promote a shift towards a vegetarian diet. As known, colorectal is one of the most prevalent cancers, and a modifiable factor influencing its occurrence is diet.
In this scientific study [1], 40 cohorts covering a total of 3,780,590 individuals were selected. Analyses indicated that higher consumption of red meat was associated with an increased risk of both colon and rectal cancer. This association has also been investigated by other researchers. A study conducted by Bernstein et al. demonstrated a strong correlation between the amount and frequency of meat consumption and colorectal cancer [2,3]. Additionally, studies have noted that increased consumption of grilled, stewed, or processed red meat also raises the risk of colorectal cancer [4].
Given the rising consumption of red and processed meat, we believe it is essential to educate about the potential health consequences. Instead of consuming meat, incorporating plant-based products into the diet is advisable. Particularly relevant to the topic of a vegetarian diet is a study conducted by Orlich et al. [5]. From 2002 to 2007, they observed 96,354 patients categorized into groups based on their diet, including non-vegetarians, vegans, lacto-ovo vegetarians (who also consume eggs, milk, dairy products, honey), pescovegetarians (including fish and seafood consumption), and flexitarians (severely restricted consumption of red meat but not entirely eliminated). The patients were followed for an average of 7.3 years, during which 380 cases of colon cancer and 110 cases of rectal cancer were recorded. Significantly lower incidences of colorectal cancer were observed among patients following a vegetarian diet compared to those consuming meat. Lower incidence was also observed among patients following various forms of a vegetarian diet [5]. The study estimated that a vegetarian dietary pattern could reduce the incidence of colorectal cancer by up to 20%. Additionally, it is worth noting that a vegetarian diet reduces the occurrence of obesity...
