Common primary sources of saturated fats in the diet include foods like red meat, full-fat dairy products, butter, and processed snacks. These fats are often found in items like cookies, cakes, and fried foods. While the body requires some saturated fat for essential functions, excessive consumption can lead to increased levels of LDL cholesterol and heightened risks of heart disease. It’s important to balance these sources with healthier fat options such as monounsaturated and polyunsaturated fats from fish, nuts, and oils.
