What Are PUFAs (Polyunsaturated Fats)?

food pufas

You might have seen me talk about PUFAs before, but what the heck are they?
▪️
There are three different kinds of fats and in their molecular structure: ❎Saturated fats have NO double bonds between carbon atoms, making them the most stable
➕Monounsaturated fats have one (mono) double bond making them less stable
➕➕Polyunsaturated fats (PUFAs) have more than one (poly) double bond, making them the least stable
▪️
PUFAs are what you’ve grown up eating. They include industrial seed and vegetable oils like canola, safflower, cottonseed, rapeseed, grapeseed, palm kernel seed and corn. They also include “healthy” oils like fish, flax and hemp, as well as margarines.
▪️
In the 1950s Ancel Keys unveiled his biased, money and personal ambition-driven Diet-Heart hypothesis that blamed saturated fat for heart disease. In 1955 President Eisenhower had a heart attack and the whole world started eating less fat and only the “heart-healthy” kind (PUFAs).
▪️
"The rush to banish animal fats from our diets has exposed us to the health risks of trans fats and oxidizing vegetable oils.” - Nina Tiecholz, The Big Fat Surprise
▪️
PUFAs go rancid when exposed to light, heat and/or oxygen. They create oxidative stress and free radicals, and in excess can be drivers of disease.
▪️
They also lack fat-soluble vitamins like REAL Vitamin A (retinol), K and D, which we need for a healthy metabolism and to create energy. It’s no wonder only 88% of us are metabolically UNhealthy and we’re all chronically fatigued...we can’t create energy!
▪️
Did you know the body is more likely to store PUFAs v saturated fat?
▪️
IMO, the introduction of more PUFAs into our diets is one of the biggest reasons - if not the biggest reason - we’re all more sick, tired and fat than ever today.
▪️
Just look at MOTHER NATURE: mammalian milk contains 50% saturated fat and 15% polyunsaturated fat. Yet most of the fat in our diet is PUFA.
▪️
If we can swap crappy oils for more ancestral saturated fats that are stable, do not oxidize and have been consumed for FOREVER, we can begin to push our body towards STABILITY and health.
▪️
I challenge you to take a look in your pantry and start chucking!
