My understanding is that most foods contain fats which are essential. But the saturated fats are the ones that could possibly cause the most problem. So to reduce them might be an idea.
Like so much advice it depends on the individual.
As someone who has been using fats for fuel instead of carbohydrates for a number of years now - saturated fats pose no risk to me because I break them down for energy and they do not contribute to my cholesterol levels.
In fact since embarking on a very high fat very low carb regime four years ago my cholesterol levels are healthy whereas they were dangerously unhealthy prior to my change of diet and I had early stage non alcoholic fatty liver disease.
Prior to my high fat very low carb diet I had avoided saturated fat and ate polyunsaturated and kept to a low fat and unprocessed food and high fibre diet with no sugar and lots of vegetables and always cooked from basic ingredients.
So for some people - mainly those who are fine with keeping their carbs very low to ensure the fats get metabolised - saturated fats (I stick to unprocessed still - coconut oil, olive oil, butter and lard and cocoa butter) are beneficial.
If I reduced my fat intake I would quickly become headachy and tired and lose concentration and not have the energy to exercise etc The body needs fuel and if one doesn't provide it as carbs then one needs to provide it as fat and unsaturated fats are these days recognised to be far more problematic than saturated fats.
I had links to the science behind it somewhere but haven't the time to dig them out right now - maybe I will find them later if people are interested.
A small amount of unprocessed saturated fats in a carb-fuelled lifestyle is safer and healthier than polyunsaturated processed fats.
