They absolutely do have a nervous system.
Whether or not they feel pain is debateable. Some scientists think they do, others don't, or at least don't think they experience pain like higher animals do. There are many people who believe that they are sentient beings.
Also, you might want to consult a chart about fat content in food. You are right that avacados are high in fat, but bananas are not. They have less fat per gram than carrots.
