Final answer:
Todd should opt for toppings high in omega-3 fatty acids or polyunsaturated fats like avocado or nuts for his toast, which help manage LDL-cholesterol levels and improve heart health.
Step-by-step explanation:
Todd could choose to put ingredients rich in omega-3 fatty acids like avocado or nuts, or spreads that contain polyunsaturated fats on his whole grain toast to help with his LDL-cholesterol level.
Foods high in omega-3s, such as flaxseeds and chia seeds, that can be added to toast are particularly beneficial since they not only help to lower LDL ('bad cholesterol'), but also have the potential to elevate HDL ('good cholesterol') levels. Additionally, he should avoid toppings rich in saturated and trans fatty acids, which can increase LDL and decrease HDL levels.
Healthy dietary choices alongside regular physical activity are key to maintaining optimal cholesterol levels. The inclusion of whole grains is part of a balanced diet which supports heart health. Todd should make sure to incorporate other cholesterol-lowering foods into his diet and limit his intake of foods high in saturated fats, as suggested by health guidelines.
