The 7 Countries Study, upon which the hypothesis that saturated fat causes heart disease was based, has been proven to be highly flawed and misleading. Ancel Keys intentionally left out the data from many countries that contradicted his claims. During the last 20 years many studies have come out showing there’s no correlation between saturated fat and heart disease, and pretty weak association between high LDL and heart disease. Obesity, insulin resistance and systemic inflamation are much higher predictors. And there’s a lot of information to suggest seed oils - canola and soy bean oils especially - are quite harmful.
