We have talked about this several times before; it is worth the repetition!
Fruits and vegetables provide essential vitamins and minerals important for keeping the body cells and tissues in a good state thereby producing good health, (and making you look younger than you really are!).
They reduce the risk of certain cancers, stroke, heart diseases, and disease involving the digestive system. They help control the blood pressure, and people with diabetes have better blood sugar control if fruits and vegetables are correctly introduced in their meals. (Consult your doctor for details.)
They are low in calories, and hence reduce the total calories intake if major portions of daily meals are replaced with them. Many people have recorded remarkable weight loss when this is coupled with relevant exercises, like skipping.
They contain vitamins that are important in improving vision and preventing conditions that lead to loss of vision and blindness. And so on.
The benefits are numerous. And it is readily available and affordable.
Go for it! Go for the first and best food given to humanity.
