Dietary Patterns and High Cholesterol Management
Adopting healthy dietary patterns is a key strategy for managing high cholesterol. Diets such as the Mediterranean diet, the Dietary Approaches to Stop Hypertension (DASH), the Portfolio diet, vegetarian diets, and low-carbohydrate diets are all recommended for reducing cardiovascular risk and improving cholesterol profiles. These diets emphasize increased intake of fruits, vegetables, whole grains, legumes, nuts, and healthy fats, while limiting saturated fats and cholesterol-rich foods. Consistent adherence to these dietary patterns has been shown to lower LDL cholesterol and overall cardiovascular risk in both the general population and individuals with familial hypercholesterolemia (FH) Popiołek-Kalisz2025Siddique2020Gomez-Delgado2020.
Role of Specific Nutrients and Foods in Lowering Cholesterol
Saturated Fat and Dietary Cholesterol
Reducing saturated fat intake is particularly important for lowering LDL cholesterol, especially in people with genetic predispositions like FH. Lowering dietary cholesterol also contributes to modest reductions in serum cholesterol, but the effect is smaller compared to reducing saturated fat. Combining reductions in saturated fat, dietary cholesterol, and trans fats, along with increasing soluble fiber, is most effective for lowering cholesterol levels Gidding2019Popiołek-Kalisz2025Grundy2016+1 MORE.
Soluble Fiber and Plant-Based Foods
Increasing soluble fiber intake—found in foods like oats, legumes, fruits, and vegetables—can significantly lower LDL cholesterol. Plant-based foods, including soy protein and certain probiotic strains, also contribute to cholesterol reduction Ge2024Popiołek-Kalisz2025Gomez-Delgado2020.
Phytosterols and Other Supplements
Phytosterols (plant sterols and stanols), berberine, garlic supplements, and polyphenol extracts have been shown to reduce total and LDL cholesterol by 3–25% in people with high cholesterol. These supplements work by blocking cholesterol absorption in the intestines, increasing bile acid excretion, and enhancing the liver’s ability to clear LDL cholesterol Ge2024Malhotra2014Shafiq2010+1 MORE.
Mycoprotein and Alternative Proteins
Replacing meat and fish with mycoprotein, a fungal-derived protein source, has also been shown to reduce serum cholesterol in overweight and hypercholesterolemic adults .
Dietary Interventions in Familial Hypercholesterolemia
For individuals with familial hypercholesterolemia, dietary management is an important supportive therapy alongside medication. While medication remains the cornerstone of treatment, dietary changes—especially reducing saturated fat and increasing fiber and phytosterols—provide additional benefits. However, evidence from clinical trials is limited regarding the long-term impact of diet alone on major health outcomes in FH, highlighting the need for more research Malhotra2014Shafiq2010Gidding2019+1 MORE.
Personalized Nutrition and Lifestyle
Personalized nutrition, which tailors dietary recommendations to individual needs and preferences, can help optimize cholesterol management. This approach may include weight management, increased physical activity, and adjustments in macronutrient intake to achieve the best results for each person .
Conclusion
Dietary management plays a crucial role in lowering high cholesterol and reducing cardiovascular risk. The most effective strategies include adopting healthy dietary patterns, reducing saturated fat and cholesterol intake, increasing soluble fiber, and considering supplements like phytosterols. For those with familial hypercholesterolemia, dietary changes complement medication and provide additional health benefits. Personalized nutrition and lifestyle modifications further enhance cholesterol control and overall heart health Ge2024Malhotra2014Shafiq2010+7 MORE.
