Final answer:
The claim that plant sources of fat are beneficial for the heart, as they are typically high in monounsaturated and polyunsaturated fatty acids, is true. These fats lower LDL cholesterol and decrease heart disease risk.
Step-by-step explanation:
The statement that plant sources of fat are good for the heart because they are usually high in monounsaturated and polyunsaturated fatty acids is True. These types of fats are healthier than saturated fats because they tend to lower LDL cholesterol levels and reduce the risk of heart disease. Plant oils like olive and peanut oil, nuts such as almonds and pecans, and avocados are predominantly monounsaturated fat sources. On the other hand, polyunsaturated fats are found in plant oils like soybean and corn oil, fish, flaxseed, and some nuts. A balance of these unsaturated fatty acids is key, particularly emphasizing omega-3 fatty acids found in fish like salmon, which are known for their heart-health benefits.
