Dietary Interventions for Lowering Cholesterol

Primary Dietary Targets for LDL Cholesterol Reduction

The American Heart Association recommends reducing saturated fat to <7% of total energy intake, as saturated fat has a greater impact on raising LDL cholesterol than dietary cholesterol itself 2, 4, 5
Limit trans fat to <1% of energy intake by avoiding partially hydrogenated oils found in commercially fried and baked products 2
General population should limit dietary cholesterol to <300 mg/day, while individuals with elevated LDL, diabetes, or cardiovascular disease should limit it to <200 mg/day 1, 2, 4, 6

Consume 2 g/day of plant stanols/sterols, available in fortified margarines, orange juice, or soft gel capsules, which lowers LDL cholesterol by 10-15% 1, 4
Increase soluble fiber to 10-25 g/day from sources like oats, beans, vegetables, and psyllium, which provides 5-10% LDL cholesterol reduction 4, 5
Replace saturated fats with polyunsaturated or monounsaturated fats, rather than simply reducing total fat, and choose liquid vegetable oils over animal fats 2, 6

Select fat-free or low-fat dairy products instead of full-fat versions, and choose lean cuts of meat, removing poultry skin before eating 1, 2
Limit processed meats high in saturated fat, and use grilling, baking, or broiling instead of frying 1
Emphasize deeply colored vegetables and fruits, and replace refined grains with whole grains 1

Evaluate LDL response after 6 weeks of dietary changes, and re-evaluate after another 6 weeks before considering medication 4
Monitor adherence every 4-6 months, and expect a total potential LDL reduction of approximately 20% with comprehensive dietary intervention 4

Weight loss enhances all lipid-lowering dietary interventions, and even modest weight loss improves dyslipidemia before reaching ideal body weight 4, 5
Individuals with elevated triglycerides should use a moderate-fat diet with monounsaturated fats, rather than a very low-fat/high-carbohydrate diet 4
Older adults can benefit from small improvements in LDL, given high event rates 1
