According to a recent study, eating as little as 2 rashers of bacon, slices of ham or 2 small slices of roast beef will increase your chances of getting colon cancer. Also, according to the study alcohol was linked with an increase in colorectal cancer too. whereas fibre from bread and breakfast cereals was associated with a reduced risk. I have an issue with these studies in general, but I must admit, it looks pretty evident in this study. Relying on modern data. So my question is, given the climate impact cattle farming has on the environment and the ever growing links to cancer, is it time we looked at red and processed meat consumption? https://academic.oup.com/ije/advance-article/doi/10.1093/ije/dyz064/5470096 Abstract Background Most of the previous studies on diet and colorectal cancer were based on diets consumed during the 1990s. Methods We used Cox-regression models to estimate adjusted hazard ratios for colorectal cancer by dietary factors in the UK Biobank study. Men and women aged 40–69 years at recruitment (2006–10) reported their diet on a short food-frequency questionnaire (n = 475 581). Dietary intakes were re-measured in a large sub-sample (n = 175 402) who completed an online 24-hour dietary assessment during follow-up. Trends in risk across the baseline categories were calculated by assigning re-measured intakes to allow for measurement error and changes in intake over time. Results During an average of 5.7 years of follow-up, 2609 cases of colorectal cancer occurred. Participants who reported consuming an average of 76 g/day of red and processed meat compared with 21 g/day had a 20% [95% confidence interval (CI): 4–37] higher risk of colorectal cancer. Participants in the highest fifth of intake of fibre from bread and breakfast cereals had a 14% (95% CI: 2–24) lower risk of colorectal cancer. Alcohol was associated with an 8% (95% CI: 4–12) higher risk per 10 g/day higher intake. Fish, poultry, cheese, fruit, vegetables, tea and coffee were not associated with colorectal-cancer risk. Conclusions Consumption of red and processed meat at an average level of 76 g/d that meets the current UK government recommendation (≤90 g/day) was associated with an increased risk of colorectal cancer. Alcohol was also associated with an increased risk of colorectal cancer, whereas fibre from bread and breakfast cereals was associated with a reduced risk.
