What one or two sustainable heart-healthy swaps improved your lipid profile?

[EmilyVG]

After a recent cholesterol panel showed my LDL is borderline high, my doctor recommended adopting a more heart-healthy diet, but I'm finding the information overload confusing with conflicting advice on fats, carbs, and specific diets like Mediterranean or DASH. I cook for my family, so any changes need to be practical and budget-friendly. For those who have successfully improved their lipid profiles through dietary changes, what were the one or two most impactful yet sustainable swaps you made in your everyday meals, and how did you handle social situations or cravings without feeling overly restricted?
