## **Core Concept**
The dietary goals for patients at high risk of coronary heart disease (CHD) focus on reducing the intake of substances that can increase the risk of heart disease, such as saturated fats, trans fats, and cholesterol, while promoting the consumption of nutrients that help lower this risk, like soluble fiber, healthy fats, and antioxidants. These dietary adjustments aim to manage lipid profiles, blood pressure, and overall cardiovascular health.

## **Why the Correct Answer is Right**
Increasing the intake of **saturated fats** (Option C) is not recommended for patients at high risk of coronary heart disease. Saturated fats can raise levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol, which is a known risk factor for CHD. Instead, dietary guidelines recommend limiting saturated fats and replacing them with unsaturated fats to help improve lipid profiles.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Increasing soluble fiber intake is beneficial as it can help lower LDL cholesterol levels. Soluble fiber forms a gel-like substance in the stomach that can bind to cholesterol and bile acids, removing them from the body, which in turn reduces the amount of cholesterol produced in the liver.
- **Option B:** Decreasing trans fatty acids is a recommended goal. Trans fats can increase LDL cholesterol and decrease high-density lipoprotein (HDL) cholesterol, or "good" cholesterol, thereby increasing the risk of heart disease.
- **Option D:** Reducing dietary cholesterol is also a recommended goal. Dietary cholesterol can raise LDL cholesterol levels, and limiting intake can help manage blood cholesterol levels.

## **Clinical Pearl / High-Yield Fact**
A key dietary recommendation for patients at risk of coronary heart disease is the **DASH diet** (Dietary Approaches to Stop Hypertension) or a similar heart-healthy eating plan that emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy products. This type of diet is rich in soluble fiber, potassium, and antioxidants, which can help manage blood pressure and cholesterol levels.

## **Correct Answer:** . Increase saturated fats.
