I have a question on sweet potatoes. Someone told me that eating one sweet potato before a workout is a great source of energy and it does not contain any bad cholesterol. What is your take on this?

Sweet potatoes are a great source of energy! They are full of complex carbohydrates (25 grams = 100 calories) for lasting fuel with a little protein (approx. 2 grams per cup). Sweet potatoes do not contain any cholesterol or saturated fat. They have a good fiber content, providing 4 grams per medium potato, which is beneficial for watching your cholesterol.

They are so easy to microwave and eat with a spoon right from the peel when sliced length-wise. No condiments needed! Kept cold, chunks of cooked sweet potato can be dressed up to make savory or sweet. Avoid fried sweet potato pre-workout as you don’t need the added fat slogging you down and hampering performance.
