In 2015, the World Health Organization cautioned that processed meats (salted, cured, fermented, or smoked) might increase the risk of cancer. This claim was well-backed by science. Research from that year found that eating 50 grams of processed meat per day raises the chances of colorectal cancer by 18%. Processed red meat poses the most risk, and 3% of all cancers are linked to it, according to Cancer Research UK. Still, experts say that this is a reason to limit processed meat, not cut it out. The occasional hamburger shouldn’t hurt you.
Some juice claims they contains fruit, but that doesn’t make it healthier than soda. In 2019, a study in The BMJ reported that even 100% real fruit juice is “significantly associated with the risk of overall cancer.” Although juices are a bit better than soda due to their vitamins and fiber, their high sugar content still poses a risk. Dr. Mathilde Touvier, who lead the research, recommends consuming less than one cup of juice per day. He added that, despite fruit juice’s healthy reputation, participants also suffered from type 2 diabetes and obesity, which are risk factors for cancer.
