If you ate a jelly doughnut for breakfast the largest component of energy would come from the?

The largest component of energy in a jelly doughnut comes from carbohydrates. Carbohydrates are the body's main source of energy, and they are broken down into glucose, which is then used for energy by the cells in the body. Jelly doughnuts are made with refined carbohydrates, such as white flour and sugar, which are quickly broken down and absorbed by the body. This can cause a spike in blood sugar levels, followed by a crash. Complex carbohydrates, such as those found in whole grains, are digested more slowly and provide a more sustained source of energy.
