Does kiwi have energy?

Yes. All fruits and vegetables contain carbohydrates. Carbohydrates are broken down in the body to produce energy, although some are more efficient than others. That is, complex carbohydrates, ie those found in high fiber fruits and vegetables, tend to break down and release energy slowly over time, whereas simple carbohydrates, ie processed sugar, break down and release energy quickly, and thus are used up quickly. This is why people who consume a lot of processed sugar, such as that found in many sodas, sometimes report a sudden "energy crash".
