Complex carbohydrates are formed by tens or even hundreds of glucose molecules linked together. Two of the most important complex carbohydrates for athletes to recognize are starches and fibers.
Starches are found most plentifully in grains such as rice, wheat, and oats, but also in tubers such as potatoes and in legumes such as beans. Starch is essentially the energy that plants store as their own energy source. When we eat starches, this plant energy becomes human energy. Our bodies break down plant starch to units of glucose that are sent to our blood and taken up by our cells, or stored in our liver or muscles in long chains called glycogen.
