A very, very quick history lesson: Way back in the 1950’s, there was a scientist named Ancel Keys. He did some studies that indicated that high fat diets were correlated with higher risk of heart disease. There’s a ton of debate whether he presented the data correctly, but that’s a whole other story. A few years later he did some lab tests, feeding test subjects high fat diets to prove his theory.
And his “fat and cholesterol are bad” theory became the basis for low fat diet recommendations for the next 50+ years.
Well it turns out that in his lab experiments, he wasn’t feeding the subjects (both rats and people) animal fats, or natural plant fats like coconut oil. He was feeding them margarine. Man-made hydrogenated margarine. And that margarine was 48% trans fats!
Fast forward to 2015. The FDA (sort of) bans trans fats in processed foods because it significantly increases the risk of heart disease. It only took them 65 years. Actually, over 100 years… Crisco was introduced in 1911.
So… we know that trans fats are bad. That absolutely does not mean all fats are bad.
Natural fats like those found in grass-fed beef, avocados, eggs, coconut and olives are very good, nutritious foods and should be part of what you eat every day. So enjoy your fat. Cook with it, eat it, savor it. It’s good stuff.
