Sure… this was drilled into my brain at Miami, where eating disorders were rampant. A lot of female students were legitimately consuming insufficient quantities of fat and it was a problem.
Most Americans consume WWWWWWAAAAAAAAAAYYYYYYYYYYYY too much fat though. Myself included.
Fortunately I tend to not eat too much. I tease my sister that it’s harder to gain weight than lose it. Sometimes I wonder if the hungry signals in my brain don’t work as well as others because occasionally I’ll just forget to eat until I get a headache.
There was never any evidence against dietary cholesterol. That was a marketing thing.
My father was a gastroenterologist, but he taught metabolism at a major medical school. Back in the 70s he told me that the amount of cholesterol in your blood is determined by how much cholesterol your body manufactures, and is almost uncorrelated with dietary cholesterol.
While its true that cholesterol production is partially (and importantly) driven by genetics (hormones levels, lipids, etc..) what you eat can influence the level of “good” HDL cholsterol vs “bad” LDL cholesterol.
Total cholesterol is not as relevant as some people think (unless it is absurdly high but then there is usually an underlying medical reason for this)
Focusing on eating high PUFA/MUFA foods (Polyno and mono-saturated fatty acids) tends to promote HDL choesterol vs LDL cholesterol. Saturated fats do the opposite if you eat a diet that contains a high % of them.
So yes, you can eat bacon just make sure you then also eat things like Olive Oil (high in MUFA) to balance things out.
The reason why LDL is seen as the “bad” cholesterol is that the oxidised variant of LDL cholesterol is uniformly bad for you (so the the more LDL you have in your bloodstream and the more inflammation you experience, the higher the chances of having more oxidised LDL floating around in your bloodstream. This then can create problems with blockages).
I didn’t say uncorrelated with diet, I said uncorrelated with dietary cholesterol. Eating saturated fats increases the amount of cholesterol you make. And it’s not even as simple as that, different fatty acids have different effects on your metabolism. So cocoa butter is a fairly saturated fat but is not very bad for you. Sadly, lard is a moderately unhealthy fat to eat. At least the naturally saturated fats like what’s in lard raise both your LDL and HDL cholesterol, and the HDL helps clean up after the LDL. Trans fats mostly just increase the production of LDL cholesterol, which is why they are so bad for you.
Also, sadly, as @knoath says, cured meats have been implicated in promoting cancer.
But, the good news is that eggs are pretty good for you. Eggs are one of the few foods that are really high in dietary cholesterol, and got a bad rap for a few years. But they are very dense in valuable nutrients for the number of calories they contain.
