Dietary changes can indeed impact protein absorption and cholesterol levels without the use of medications like Lipitor. Consuming a diet rich in lean proteins, such as fish, poultry, legumes, and nuts, can enhance protein absorption in the body. Additionally, incorporating foods high in fiber, like fruits, vegetables, and whole grains, can help lower cholesterol levels by reducing the absorption of cholesterol in the intestines. Limiting saturated and trans fats, as well as refined sugars and carbohydrates, can also aid in managing cholesterol levels naturally. These dietary modifications can contribute to overall health and may reduce the need for cholesterol-lowering medications like Lipitor [3][2][1].
