What dietary change is recommended to help manage cholesterol levels?

Increasing soluble fiber intake is recommended for managing cholesterol levels because soluble fiber has been shown to help lower low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. Soluble fiber helps to bind cholesterol in the digestive system, preventing its absorption into the bloodstream. As soluble fiber ferments in the gut, it forms a gel-like substance that captures cholesterol and carries it out of the body through feces. Foods high in soluble fiber include oats, barley, beans, lentils, fruits (such as apples and oranges), and vegetables like carrots.

The other options do not align with effective strategies for cholesterol management. Decreasing protein intake generally does not directly impact cholesterol levels in a beneficial way, as protein sources vary widely in their effects depending on whether they are plant-based or animal-based. Increasing saturated fat consumption is contrary to dietary recommendations for lowering cholesterol, as saturated fats can raise levels of LDL cholesterol. Reducing overall carbohydrate intake does not specifically focus on cholesterol management and may not provide the targeted benefits associated with soluble fiber consumption.
