Yes, cholesterol levels can rise shortly after eating, especially if the meal is high in saturated fats. When we consume foods high in saturated fats, our bodies produce more cholesterol to help digest and absorb these fats.

It is important to maintain a balanced diet and limit intake of foods high in saturated fats to help manage cholesterol levels. **
