First up - i'm a crank - my opinions are far from the 'conventional wisdom' that saturated fats are bad.
It's a big topic and i won't get far before i get bored with my two finger typing.
Basically back in the 60/70's there were two schools of thought
- the british scientists who thought sugar (and carbs) caused heart disease
-and the americans, who said it was cholesterol (and fat- guilty by association) that did it.
The americans won and for 60 years they have been demonising cholesterol and saturated fat,
If you are interested then these links will bring you up to date
- it's not hard to find the complete opposite being preached by someone else so you need to decide who you trust - me, i trust 3 million years of evolution

This guy is worth listening to, PhD in nutritional science - he covers the whole subject and you won't find a more complete summary of the topic,

i think he's been on a ketogenic diet (very low carb) for a couple of years while being a surgeon and athlete with no damage to his kidneys
Olive oil is good if it is not old and oxidised (rancid)
"Olive oil isn’t harvested by leaving open containers under leaking, dripping olives on the branch, nor is that liquid sloshing around inside a coconut pure oil. I’m not trying to disparage processing in and of itself. It takes a certain amount of processing to get any sort of oil, but a good general rule is to avoid consuming the oils that require processing on a large scale. If it involves an industrial plant, multiple stainless steel vats, a deodorizer, a de-gummer, and the harsh petroleum-derived solvent known as hexane, I wouldn’t eat it."
