Study: Consuming Plant-Based Oils Instead of Butter Could Significantly Reduce Mortality

A recent study analyzing data from over 200,000 individuals over 30 years found that consuming plant-based oils instead of butter could significantly reduce mortality rates. Higher intake of oils such as soybean, canola, and olive oil was associated with lower total, cancer, and cardiovascular disease mortality, while butter intake was linked to increased risk of total and cancer mortality. The study suggests that the difference in health effects may be due to the types of fatty acids found in butter and oil, with butter being rich in saturated fats and plant-based oils containing more unsaturated fatty acids.

Replacing just 10g of butter a day with equivalent calories of plant-based oils could lower cancer deaths and overall mortality by 17%, according to the study's substitution analysis. This research adds to the growing body of evidence supporting the health benefits of a plant-based diet, including improving heart health and cardiometabolic health. Despite this evidence, many Americans still believe that animal protein is necessary for health, but the study's authors suggest that a simple dietary swap from butter to oils could lead to significant long-term health benefits and prevent a substantial number of deaths from chronic diseases.
