Longevity and National Traditions of Butter Consumption

To reveal a possible correlation between butter consumption, longevity, and quality of life, the authors reviewed the cultural and historical traditions of butter production and consumption in different countries and performed a quantitative analysis of butter consumption per capita by continent. The correlation analysis covered 182 countries and was summarized as a regression model. The model showed that a per capita consumption of ≤7.5 kg correlates with a long life expectancy. Russians consume 2.8 kg of butter per capita, which exceeds the 2 kg recommended by the Ministry of Health but remains far beyond the critical limit revealed in this study. The global average life expectancy for 2.8 kg is 79 years, which exceeds the life span of 78 years targeted by the National Project of Long and Active Life for 2030.
