17 Jul 2024 --- By using blood fat profiles, researchers have confirmed the health benefits of switching to a diet rich in plant-based unsaturated fats instead of one high in saturated animal fats. These dietary changes affect the fat composition in the blood, which influences long-term disease risk. Although the WHO recommends replacing saturated fats with plant-based unsaturated oils to reduce cardiometabolic risk, research to verify this has been challenging. The new study uses lipidomics — detailed lipid (fat) measurements — which enabled the research team to link diet and disease.
