The highest Sat.Fat sources are like Jman99 mentioned everything Coconut (Oil,Milk,Cream).
Unrefined Palmfett has also quite some sat.fat.
Butter,but personally I’d opt for Goat&Sheep dairy….they have a more favorable fatty acids composition imho….and usually better digestible.
Cacaobutter is also high in sat.fats,so you can either make your own chocolate with cacaobutter and/or Coconut Oil…..or happily eat storebougth chocolate,though I’d be causious that it doesnt have soy-lechitine in it which a lot of pre-made bars have.
