Eating real foods (e.g., whole foods rather than highly processed foods) is good advice overall. But replacing mono and poly unsaturated fats with saturated fats is total nonsense. We have thousands of studies spanning decades showing that increased saturated fat consumption leads to elevated LDL-C and elevated LDL-C is causitively associated with higher rates of CVD. There's no reason to replace olive oil with butter and beef tallow.
