In 2018, a California judge was asked to rule on a question that many scientists are still attempting to answer: Does drinking coffee increase your risk of cancer?
Many scientific studies have found associations between drinking coffee and a number of health benefits, including longer life spans and reduced risk of heart attack. But some researchers say it could be linked to cancer, since a potentially carcinogenic chemical called acrylamide forms when coffee beans are roasted.
Last spring, the California judge ruled that coffee companies must post warnings about acrylamide, in accordance with Proposition 65, a state law that requires businesses to alert residents about significant exposures to toxic chemicals.
California’s Office of Environmental Health Hazard Assessment is now attempting to reverse that ruling, arguing that coffee consumption poses no significant risk. Their stance is backed by the US Food and Drug Administration, which said that cancer warnings “would be more likely to mislead consumers than to inform them.”
