hello friend,
Eating fresh fruits is your good thinking but there are several other food nutrients required to our body that are not completely fulfilled by fruits. The body requirement of protein, carbohydrates and other nutrients are not completely covered by taking only fruits. Better you go for proper food plan. It will be more beneficial to you.
Firstly you should have complete knowledge of all the essential vitamins, minerals and natural nutrients, their natural sources and daily requirement to the body to stay fit and healthy lifelong. I sugest you to visit some good educational health websites that cover all the information about proper health care.
