The fats that you eat could be the difference between a long healthy life and one where you

0:06.8

battle chronic disease. But choosing healthy fats, thanks to marketing and low quality information online,

0:12.4

is really harder than it needs to be. Here is a scenario that most of us are faced with each week.

0:18.5

Picture this. You're standing in the grocery store, staring at rows

0:22.5

of cooking oils, extra virgin olive oil, coconut oil, canola oil, avocado oil, ghee, and then only a

0:29.1

short walk away butter and margarine in the refrigerated section. Which one or ones should you choose?

0:34.6

If you've ever felt overwhelmed by this decision, you're not alone. By the end of

0:38.8

this video, you'll navigate the grocery store like a nutrition expert, or at least that's my hope,

Saturated fatty acids like those that predominate in butter, ghee, coconut oil, palm

oil, cocoa butter, have single bonds between the carbon atoms.

1:23.9

The absence of double bonds allows the fats to pack tightly at room temperature, forming a solid like butter.

1:31.3

Whereas unsaturated fats, like those that predominate in olive oil, canola oil, avocado oil, etc.,

1:37.3

have one or more double bonds between carbon atoms, sometimes referred to as a kink in the carbon chain,

1:43.3

preventing the

1:44.8

fats from packing tightly together, which is why they're a liquid at room temperature.

If a fatty acid has one double bond, it's a mono-unsaturated fat. If it has two or more double
