But do remember that it's only saturated fats which increase LDL, not poly- or mono-unsaturated, which you don't want to cut, probably.
Also, replacing sat fats with poly- or mon-unsaturated generally has only a modest impact, depending on how much you're cutting by: for every 1% of daily calories from sat fats replaced by unsaturated or carbs, figure something like 0.03 - 0.05 mmol/L reduction in LDL. So to get a 0.3 mmol/L reduction in LDL via this method, figure replacing something like 5% - 10% of yr daily calories from sat fats with something else.
(All fats are about 9 cals per g. If you're eating 2,000 cal per day, that means replacing 100 - 200 sat fat cals = about 11 - 22 sat fat g)
Another dietary thing you might try is upping fibre. This generally reduces LDL, maybe quite effectively, but it's pretty variable, I think.
I think every just about food has some combination of satfats, poly-unsatfats and mono-unsatfats, so if you're trying to optimise it's a juggling act. Eg:
- If you cut almonds you're cutting a small amount of satfats but a much larger amount of mono and poly. Probably not a good move. I eat a ton of them and they are loaded with other nutrients - one of the last things I'd ever cut.
- It works a bit better with peanuts, because they have a higher proportion of satfats, but they still have a lot more unsaturated. I eat quite a lot of them, partly because they are a pretty good source of protein, and they offer a pretty good protein/satfat trade-off compared to many other foods.
- Cheese has more satfats than unsaturated and it's one of the first things I cut when I was zapping my LDL. YMMV; depends how aggressive you want to be.
- Avocados - as for peanuts, higher satfats than eg almonds but still much less than unsatfats, and great load of other nutrients and fibre. You can take my avocado when you prise it out of my cold dead hand.
Hmmm. It's all a bit of a vortex, I suppose. Why not just take a statin if you want to crunch your LDL? It will almost certainly have a bigger impact than diet changes.
Anyway, this is a useful tool for juggling:

Me: Started with LDL = 3.2. I'm "high risk" so I wanted to bring it down as low as possible, probably more aggressively than you need to. I eat less than 6% cals from satfats, mainly plant based, and 70g+ of fibre. and I take the max dose of the strongest statin. My LDL is now 0.7, about as low as you can get it without moving on to newer stronger meds.
Of that reduction by 2.5, I estimate about 1.8 is due to statin and 0.7 to replacing satfats and increasing fibre.
