This June 2020 review by Ron Krauss, Arne Astrup, et al. concludes that guidelines to reduce saturated fat intake are not supported by a complete assessment of the evidence. Neither controlled studies nor mechanistic evidence indicates higher saturated fat intake increases risk of atherosclerosis or heart disease. Efforts to reduce saturated fat consumption may in fact harm public health by discouraging consumption of high-quality, nutrient-dense foods and implicitly encouraging consumption of refined grains and sugars — changes that are both more reliably linked to ill health than increased intake of saturated fat.
