Which animal fats? Beef, for instance, is quite high in trans fat.

I personally consider all animal fats to be safe.

Butter. Olive oil.

Occasionally use peanut or vegetable oil but only for frying.

I wouldn’t use any plant fats for cooking. All of them oxidize pretty quickly.

Olive oils are often fake, unless you are paying around $20 for a small bottle.

There are a number of reputable olive oils you can buy that aren't fake. I buy from the costco lineup personally. We prefer Ottavio, the one from Spain, but I believe the Kirkland Brand was also tested.

Also, can you elaborate more on why you don't use plant fats for cooking? We do the opposite here, so I'm curious.

Yup, Costco is a great source. I emailed them and asked about the fake oils. They said they do random testing of every shipment.

First, I avoid most of the m vegetable oils in general. Not just for cooking. The only exceptions is olive and coconut. Most oils are high in omega 6 fatty acids. This skews the ratio of omega 3 to omega 6 that our body desires. But cooking or heating the oils makes them even worse. It destroys good properties, oils become rancid / oxidizes during heating.

I just don’t see the reason to even use veg oils. Food tastes so much better cooked in butter or ghee, or bacon fat, or beef tallow.

I wonder why you don't have olive trees over there. Maybe a work in progress... it takes decades to grow them. Modern machines make harvest very cheap.

In Spain we have best quality for under 5€ l, so I guess globalization has not arrived to oil.

> Olive oils are often fake

what?! fake as in, it's synthetic? Or fake as in not really olive oil, but it says it is on the label?

1. Blends with other oils 2. Just other, cheaper oils 3. Olive oil, but spoiled or rancid 4. Olive oil, but lower grade than advertised

Never heard of synthetic yet. But I’m sure that’s coming.
