Dietary fats some food for thought

So I am not a doctor, or a biologist or even a nutritionist. I am a master auto mechanic plain and simple. I have been on a lifetime journey of self discovery when it comes to one of my favorite things in life: FOOD!

Feel free to swipe my ideas, whole or in part to further any factual discussion on this topic.

My speculation regarding dietary fats is this:
We know that animal and plant fats are different. Lately plant fats are all the rage while animal fats are under continuous assault. Coconut, Avocado, olive oil and the like are all dietary heroes of the moment.

I'm wondering if animal fats from flesh are different and presumably worse nutritionally speaking than say fats from dairy or eggs.

I keep hearing about how toxins are stored in fat cells within the body and you often revisit them during weight loss. My idea is that the animal fats in eggs and milk do not contain the same toxins as fat stored in the flesh of an animal.

My apologies if this was a clunky bit of business but I just wanted to throw this into the universe for the sake of sharing ideas.
