Is Cold-Smoked Mackerel Harmful? A Doctor Weighs In Iziaslav, Ukraine – June 3, 2025 – A recent video posted online by Dr. Vasyl Ornat, a physician from Iziaslav, has sparked discussion about the health risks associated with consuming cold-smoked mackerel. Dr. Ornat, responding to a viewer's question, explains that while the nitrates used in preserving the fish are indeed potentially harmful, moderate consumption is not a significant health threat. "In all methods of processing this meat, so-called nitrates are used," Dr. Ornat states in the video. "They are considered harmful products." However, he adds that consuming mackerel less than ten times a week is unlikely to pose a health risk. He concludes with a humorous observation: "Excessive breathing causes cancer, so the best recommendation would be not to breathe." This humorous statement underscores the importance of moderation in food consumption. Dr. Ornat's video highlights the importance of balanced information and responsible consumption of processed foods.
