Fuel for Performance - Sweet Potato
by Drew Whitehead
When most people look at a sweet potato they do not think, “high performance fuel”. They think, “mmmmm that would be good with marshmallows melted on top!” That is how I pictured sweet potatoes while growing up. Over the past year of eating gluten free and JERF’ing it up – #jerf : just eat real food :) I have experienced how much sweet potatoes fuel athletic performance. After my naturopath found I had a candida overgrowth from eating too many grains and sugars, I began asking myself, ”How can I get enough carbs to utilize during my workouts, races and competitions without bread? How can I get enough fiber without grains? How can I have energy without sugar?” I found myself researching for an optimal way of eating and sweet potatoes became a big part of my eating. My athletic performance has improved, I feel better, my pH is stable and my body composition is steady at 6.5%. If you are looking for some quick race fuel for your performance considering sweet potatoes may be a good idea. Here are some sweet potato benefits and facts:
