I'm turning 20 this month, I weigh about 130, and i'm 5' 6" tall. I'm a guy. Will I get any taller? Are there foods or any way to help me get taller?
No and no
Very rarely guys will grow a little between 18 and 20, but if you're showing secondary sexual characteristics like facial hair, muscle growth, and genital growth and hair, then chances are your growth plates are fused, meaning you're done growing.
At this point, eat healthy to promote bone and muscle growth. Look to see how tall your parents are, you should be around their heights.
