Some saturated fat is good for us.

Omega-3s are very, very good for us.

Monounsaturated fats are good for us. They have one double bond and usually considered “heart healthy” or neutral in their effects.

Omega-6s are good for us if balanced with the 3’s.( if not processed and refined to death.) Corn oil is a common one.

Reused (reheated) vegetable oils are really, really bad. When used repeatedly as the oil for deep fried foods, they are really, really, bad.

Trans fats are “metabolic”s poison. The acceptable level in the diet is zero. Read the product’s Nutrition Facts label.

Extra virgin (EVOO) olive oil is in a class by itself, although a plant oil. It contains a lot of compounds called phenols which are antioxidants. Translation: The stuff is really good for you and is a major component of the Mediterranean Diet (a favored way to spend the rest of your diet choices.)
