Yea... No.
The economic lesson is: restaurants that solely use good fats like avo/olive oil will go out of business. Because it cuts into their already slim profit margin. They're incentivized to use shit oils like Soy & Rape seed/Canola, & Sysco supply chains.
Granted, outliers exist. But I do my best to not eat takeout, it's almost guaranteed to have a poisonous or detrimental components.
Don't practice willful self harm, it's like punching yourself in the face.
