## **Core Concept**
The World Health Organization (WHO) advocates dietary changes to prevent heart diseases, focusing on reducing the risk factors associated with cardiovascular diseases (CVD). These recommendations primarily involve modifications in the intake of certain nutrients and food components to promote heart health.

## **Why the Correct Answer is Right**
The correct answer, , involves understanding the specific dietary recommendations made by the WHO for the prevention of heart diseases. Typically, these recommendations include reducing the intake of saturated fats and trans fats, increasing the consumption of fruits, vegetables, and whole grains, and limiting dietary cholesterol and sodium. The WHO's emphasis is on a balanced diet that helps maintain healthy blood pressure, cholesterol levels, and body weight.

## **Why Each Wrong Option is Incorrect**

- **Option B:** This could involve increasing the consumption of fruits and vegetables, aligning with WHO recommendations. Fruits and vegetables are rich in fiber, vitamins, and minerals that help protect against heart disease.
- **Option C:** This might involve reducing dietary cholesterol, which aligns with WHO guidelines. High dietary cholesterol is associated with increased risk of heart disease.
- **Option D:** This could suggest reducing sodium intake, which is also in line with WHO recommendations. High sodium intake is linked to high blood pressure, a major risk factor for heart disease.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that the WHO recommends a daily intake of at least 5 servings (400g) of fruits and vegetables to reduce the risk of chronic diseases, including heart disease. Additionally, limiting sodium intake to less than 5g per day is advised.

## **Correct Answer: A. increase intake of saturated fats**
