Following a low-meat or meat-free diet or a vegetarian diet can reduce the risk of developing cancer.
- Eating meat five times or less per week reduces the cancer risk
- Vegetarians are extremely at lower risk of developing cancer
- Consuming fish is better than meat, as it reduces cancer risk
About 247,571 (52%) of participants ate meat more than five times per week, 205,382 (44%) of participants ate meat five or less times per week, 10,696 (2%) ate fish but not meat, and 8,685 (2%) were vegetarian or vegan. 54,961 participants (12%) developed cancer during the study period.
The researchers found that the overall cancer risk was 2% lower among those who ate meat five times or less per week, 10% lower among those who ate fish but not meat, and 14% lower among vegetarians and vegans, compared to those who ate meat more than five times per week.
When comparing the incidence of specific cancers with participants’ diet, the authors found that those who ate meat five times or less per week had a 9% lower risk of colorectal cancer, compared to those who ate meat more than five times per week.
They also found that the risk of prostate cancer was 20% lower among men who ate fish but not meat and 31% lower among men who followed a vegetarian diet, compared to those who ate meat more than five times per week.
The researchers caution that the observational nature of their study does not allow for conclusions about a causal relationship between diet and cancer risk. Additionally, as UK Biobank dietary data was collected at a single time-point, rather than over a continuous period of time, it may not be representative of participants’ lifetime diets.
