Cholesterol Level Reduction Diet: essential information
Two diets, the Mediterranean diet and the DASH (Dietary Approaches to Stop Hypertension) diet, are highly recommended for managing cholesterol levels and blood pressure due to their heart-healthy components.
The Mediterranean Diet
The Mediterranean diet emphasizes a high consumption of fruits, vegetables, whole grains, legumes, nuts, and healthy fats, primarily from olive oil. It includes moderate amounts of fish, poultry, and low-fat dairy, with limited red meat and sweets. The diet is rich in monounsaturated fats (from olive oil) and fiber (from plant foods) that help lower LDL ("bad") cholesterol and regulate blood pressure. It also includes antioxidants and polyphenols that reduce inflammation and oxidative stress, both linked to heart disease. Research links the Mediterranean diet to a reduced risk of heart attack, stroke, diabetes management, lower blood pressure, and overall cardiovascular risk reduction [1][2][3][4].
The DASH Diet
The DASH diet focuses on reducing sodium intake while increasing consumption of fruits, vegetables, whole grains, lean protein (especially fish and poultry), and low-fat dairy. It encourages foods rich in potassium, calcium, and magnesium, which help lower blood pressure. The diet limits foods high in saturated fat, cholesterol, and added sugars. The DASH diet has been proven to significantly lower blood pressure and improve cholesterol profiles, reducing cardiovascular risk. Like the Mediterranean diet, it promotes dietary patterns rich in plant-based foods and healthy fats but places a stronger emphasis on sodium reduction.
Key Similarities and Benefits
| Aspect | Mediterranean Diet | DASH Diet | |----------------------------|-----------------------------------------------|---------------------------------------------| | Primary focus | Healthy fats (olive oil), antioxidants | Low sodium, minerals for blood pressure | | Fat intake | High in monounsaturated fats | Lower total fat, emphasis on lean proteins | | Fruits and vegetables | High intake | High intake | | Whole grains | Emphasized | Emphasized | | Dairy products | Moderate intake, mostly low-fat | Emphasized, low-fat | | Meat consumption | Limited red meat, moderate fish and poultry | Reduced red meat, emphasis on lean sources | | Cholesterol/lipid effect | Lowers LDL cholesterol, raises HDL, reduces inflammation | Lowers blood pressure, improves lipid profile | | Blood pressure impact | Potassium and fiber help reduce pressure | Strong focus on lowering sodium and boosting potassium |
Both diets are supported by research showing their ability to lower blood pressure and improve cholesterol profiles, thereby reducing the risk of cardiovascular disease. The Mediterranean diet additionally emphasizes anti-inflammatory and antioxidant benefits, while the DASH diet is specifically designed for hypertension management with a strong emphasis on sodium reduction.
In practice, choosing either diet supports heart health, and combining their principles can be highly effective in managing both cholesterol and blood pressure. The American Heart Association (AHA) suggests the DASH diet and Mediterranean-style diet for managing cholesterol levels. However, some people may not be able to manage their cholesterol levels with diet and lifestyle changes alone and may require medication.
Current research suggests that dietary cholesterol has a less significant impact on blood cholesterol levels than previously thought. Following the Mediterranean diet includes eating green, leafy vegetables, a variety of legumes, nuts, fresh fruits, whole grains, olive oil, and fish. People should consult a healthcare professional for advice on managing cholesterol levels. High levels of LDL cholesterol in the blood can increase a person's risk of developing cardiovascular diseases (CVD). In addition to dietary changes, individuals should take steps such as avoiding or quitting smoking, getting cholesterol levels checked regularly, and engaging in regular exercise.
The AHA published a statement indicating that the Dietary Guidelines for Americans 2015-2020 (DGA) removed the long-held recommendation to limit cholesterol to help prevent CVD. The liver creates cholesterol for the body to use, and people can also find cholesterol in the foods they eat. Making dietary changes alone may not be enough to lower cholesterol levels for some people. To help reduce their blood cholesterol levels, a person will need to limit foods that contain saturated fat. Many fruits and vegetables contain plant stanols or sterols, compounds that may help lower cholesterol. Additionally, omega-3 fatty acids, which are highly present in oily fish, may help lower LDL levels.
The Mediterranean diet is based on the traditional dietary habits of people living in the Mediterranean region. The DASH diet encourages eating vegetables, whole grains, fruits, fish, poultry, beans, nuts, seeds, vegetable oils, and fat-free or low-fat dairy products, while avoiding fatty meats, sugary beverages, sweets, sodium, full-fat dairy, and processed foods. The AHA, the American College of Cardiology (ACC), and the DGA do not provide any specific guidance regarding dietary cholesterol.
The Mediterranean diet is associated with a reduced risk of CVD and stroke, as well as improving cardiovascular health. The CDC recommends eating more foods with high amounts of fiber, such as beans and oats, as well as foods with high levels of unsaturated fats, such as olive oil, avocados, and nuts or seeds. Some people, such as those with diabetes, CVD, or familial hypercholesterolemia, may require medication to help manage their cholesterol levels. A balanced diet that includes fruits, vegetables, whole grains, lean proteins, and healthy fats, including nuts, avocados, and olive oil, may help a person manage cholesterol and blood pressure. Certain diets, including the Mediterranean and DASH diets, may help a person manage cholesterol and blood pressure as they emphasize whole foods and tend to limit sugary drinks, processed foods, and saturated fats.
Heart UK, a charity in the United Kingdom, notes that eating foods that contain cholesterol is unlikely to make a significant difference to a person's cholesterol levels in the blood. Therefore, focusing on a balanced diet rich in heart-healthy foods, such as those emphasized in the Mediterranean and DASH diets, can be an effective strategy for managing cholesterol and blood pressure levels.
- A nutritionist may recommend the Mediterranean diet, established for its heart-healthy components like the reduction of unhealthy cholesterol, regulation of blood pressure, and promotion of overall cardiovascular health.
- The DASH diet, an established diet focused on sodium reduction and promoting heart-healthy foods such as fruits, vegetables, lean proteins, and low-fat dairy, also offers benefits in lowering blood pressure and improving cholesterol profiles.
- Other nutrition experts and organizations like the American Heart Association emphasize the importance of viewing the Mediterranean diet and DASH diet not as competing diets but as complementary strategies for improving health and wellness, including managing medical-conditions like high cholesterol and blood pressure.
- Incorporating the principles of both diets, such as reducing the consumption of red meats and processed foods, while increasing fruits, vegetables, whole grains, legumes, nuts, and fish can help establish a balanced diet for promoting fitness-and-exercise, healthy nutrition, and cholesterol management.
- Unfortunately, those with certain medical-conditions, like genetic disorders such as familial hypercholesterolemia, may need to turn to more intensive measures such as medications to manage their cholesterol levels.
- In addition to dietary changes, maintaining a healthy lifestyle through regular exercise, avoiding smoking, and staying aware of one's health-and-wellness is crucial for managing cholesterol levels and reducing the risk of developing cardiovascular diseases.
- Recent science points towards the importance of plant stanols or sterols, compounds commonly found in green, leafy vegetables, certain fruits, and nuts, for helping lower cholesterol levels.
- Additionally, omega-3 fatty acids, abundant in fatty fish, have shown to be beneficial in reducing LDL cholesterol levels and promoting cardiovascular health, further supporting the heart-healthy qualities of the Mediterranean diet and other nutrition recommendations.
Additionally, CBD, often touted as a health supplement, may have potential benefits for cardiovascular health and managing other medical-conditions, though further research is required to confirm its efficacy.
