The rise in seed oil consumption has paralleled dramatic increases in obesity, heart disease, diabetes, and autoimmune conditions. Published research shows omega-6 polyunsaturated fat linoleic acid promotes oxidative stress, oxidised LDL, and chronic inflammation. The omega-6 to omega-3 ratio in Western diets shifted from 1:1 to as high as 20:1. Yet major health institutions continue to recommend seed oils as 'heart healthy,' often citing industry-funded research. The debate over seed oils vs. traditional fats remains aggressively suppressed.
