Study Links Breakfast Timing to Heart Risk, Experts Urge Caution on Causality

A nine-year observational study tracking 41,000 Americans examined their breakfast times and found a correlation between later breakfast hours and increased risk of death from heart disease. Participants eating breakfast between 8 and 9 a.m. had a 10 percent higher risk, while those eating between 9 and 10 a.m. faced a 19 percent higher risk. However, experts caution against interpreting these findings as direct causation. Professor Eitan Friedman, director of the Genetic Institute for Early Detection at Assuta Ramat Hahayal, explained in an interview with HaOlam HaBoker that the study's observational nature means it cannot prove a causal link between breakfast timing and lifespan. Friedman emphasized that the content and variety of breakfast are more important than the exact timing. He also highlighted that proven factors for improving life quality remain regular physical activity and avoiding smoking.
