I am 17 1/2 years old girl and have 4'10 height. What can I do to grow taller by atleast 3-4 inches?? please tell me what diet to follow......

Healthy lifestyle. You are most likely to reach your tallest potential height by following a healthy diet, getting appropriate sleep & and remaining physically active.Nothing you eat or drink will add inches.You can stunt your growth by the opposite, poor diet/sleep/inactivity can all take a toll.At 17.5 it is likely your growth centers have closed, and you are finished. Learn to accept your size.
