If you know that it is useful for you then you can make a habit to eat fruit.
They are tasty.
They have lot of vitamins & minerals which are important for your health.
They contain lot of fibre which your stomach needs to be digested very easily & quickly.
Your skin, hair, eyes, memory, & other body systems need it. I think when you know all that you will take fruit. Always before meal, rather 2, 3 hours before.
