How can I lower my cholesterol levels?

How to Lower Cholesterol

To lower cholesterol effectively, limit saturated fat to less than 7% of total energy intake, restrict dietary cholesterol to under 200 mg/day, add 2 grams daily of plant stanols/sterols, increase soluble fiber to 10-25 grams daily, achieve modest weight loss if overweight, and engage in regular physical activity. 1

Dietary Fat Modification

The cornerstone of cholesterol management is reducing saturated and trans fatty acids:

• Saturated fat should be limited to less than 10% of energy intake, and preferably to less than 7% 1
• Trans-unsaturated fatty acids should be minimized or eliminated entirely 1
• Dietary cholesterol intake should be restricted to less than 200 mg/day 1
• When replacing saturated fat, substitute with either carbohydrates (preferably from whole grains and fiber-rich sources) or monounsaturated fats 1

The American Heart Association guidelines emphasize selecting fat-free or low-fat dairy products, using lean cuts of meat, removing poultry skin, and limiting processed meats high in saturated fat 1.

Functional Foods and Supplements

Plant stanols/sterols at 2 grams per day can lower LDL cholesterol by 8-29 mg/dL 1:

• These are available in fortified margarines, orange juice, and soft gel capsules 1
• Must be consumed daily to sustain LDL cholesterol reductions, similar to taking medication 1
• The American Heart Association recognizes plant stanols/sterols as a therapeutic option for individuals with elevated LDL cholesterol 1

Soluble (viscous) fiber at 10-25 grams daily enhances LDL cholesterol lowering 1:

• Each gram of soluble fiber decreases LDL cholesterol by approximately 2.2 mg/dL 1
• Sources include psyllium, beta-glucans, and fiber-rich whole grains 2

Weight Management and Physical Activity

Modest weight loss significantly improves lipid profiles 1:

• Weight reduction leads to decreased plasma triglycerides and modest lowering of LDL cholesterol 1
• Even small amounts of weight loss (before reaching ideal body weight) produce beneficial effects 1
• Dyslipidemia is strongly associated with abdominal (visceral) fat distribution 1

Regular physical activity is essential 1:

• Exercise reduces plasma triglycerides and improves insulin sensitivity 1
• Physical activity should be increased as part of the comprehensive approach 1

Dietary Pattern Recommendations

Consume a diet rich in vegetables and fruits 1:

• Deeply colored vegetables and fruits (spinach, carrots, peaches, berries) should be emphasized 1
• Whole vegetables and fruits are preferred over juices 1

Select whole-grain products and limit refined carbohydrates 1:

• Replacing saturated fat with carbohydrates from whole grains shows beneficial or neutral effects on triglycerides 1
• High-sugar, nutrient-poor, calorie-dense foods should be avoided 1

Monitoring and Timeline

LDL cholesterol response should be evaluated after 6 weeks of dietary changes 1:

• If LDL goal is not achieved after initial 6 weeks, intensify dietary modifications by reinforcing saturated fat and cholesterol reduction 1
• Add plant stanols/sterols and increase soluble fiber if not already implemented 1
• Monitor adherence to therapeutic lifestyle changes every 4-6 months 1
• Assess LDL-C as early as 4 weeks after initiating interventions when clinically appropriate 3

Special Considerations for Metabolic Syndrome

For individuals with elevated triglycerides, reduced HDL cholesterol, and small dense LDL particles (metabolic syndrome pattern):

• All the above dietary modifications apply, with particular emphasis on weight loss and physical activity 1
• Dietary saturated fat restriction is especially important 1
• Incorporation of monounsaturated fats may be beneficial 1
• Improved glycemic control (if diabetic) helps address this lipid pattern 1

When Pharmacotherapy Becomes Necessary

If lifestyle modifications for 3 months do not achieve target LDL cholesterol levels (optimal <100 mg/dL, target <200 mg/dL total cholesterol), medical intervention should be considered 4:

• Approximately half of patients with elevated LDL cholesterol will ultimately require lipid-lowering drugs to achieve treatment goals 5
• Statins are the preferred first-line pharmacological treatment 5
• Ezetimibe can be used in combination with a statin or alone when additional LDL-C lowering is needed 3
