Cancer is the second leading cause of death worldwide, killing over 10 million people yearly—a number higher than deaths from wars, crime, and accidents combined.
Almost 40 percent of cancer cases are related to the foods in our fridge, especially due to processed foods, red meat, sugary drinks, alcohol, salt, and high-fat dairy.
Processed meats (like ham, bacon, sausages, hot dogs) increase colorectal cancer risk by 18 percent (50 grams daily) and stomach cancer risk by nearly 30 percent due to nitrates/nitrites and nitrosamines (IARC, WHO, 2015).
Red meat (beef, pork, lamb), especially when grilled or fried, raises colorectal cancer risk by 12 percent (100 grams daily). No safe threshold—risk rises with quantity (WCRF, 2018).
Sugary drinks and soda strongly lead to obesity, which increases risk of several cancers by up to 84 percent (colorectal, breast, endometrial, pancreatic, and more) (meta-analyses, 2019).
Alcohol has no safe dosage—even 1 drink per day raises cancer risk by 4–7 percent (breast, liver, throat, colorectal cancers), with the risk rising sharply with more intake (IARC, 2012).
Smoked foods (meat, fish, cheese) increase stomach cancer risk by up to 50 percent and esophageal cancer by 40 percent (due to polycyclic aromatic hydrocarbons and nitrosamines) (Japanese cohort studies, 2013).
Pickled and salty foods (including kimchi, pickles) can raise stomach cancer risk by 20–50 percent or more, mainly because of high salt and nitrosamine content.
Fried foods (like fries, chips, fried meat) increase risk of colon and pancreatic cancer by 20 percent; acrylamides formed in high-heat frying are linked to endometrial and ovarian cancers.
Full-fat dairy products raise prostate cancer risk by 34 percent (two or more glasses daily); also increase breast and ovarian cancer risk by 10–20 percent due to hormones and insulin-like growth factor (meta-analysis, 2016).
