Final answer:
Unsaturated fatty acids are associated with a lower risk of heart disease, while saturated and trans fatty acids increase the risk. Therefore, the claim that unsaturated fatty acids pose a greater health risk is false.
Step-by-step explanation:
The statement that unsaturated fatty acids present a greater health risk for the development of coronary heart disease is false. In fact, a diet high in unsaturated fatty acids is associated with a lower risk of heart disease, particularly due to the presence of omega-3 unsaturated fatty acids found in foods like salmon. On the other hand, saturated fatty acids, which are commonly found in animal fats and some processed foods, have been shown to increase the risk of heart disease. Additionally, trans fatty acids, often present in processed foods, can be even more detrimental to heart health than saturated fatty acids.
