How do I get taller?

I`m 12 and I`m around 4`9" and I want to get taller, My friends are like 5`3" or 5`5" and some are my height. I dont think I`ve been growing that much so I need help, Even my sister is taller than me. I mostly eat meats and rice, a but I also eat egg, chicken, corn, oranges, fish, fruits, barely some vegetables, and other things. I think I get enough milk but I still dont get why im not growing, is there a problem with my diet?

Nah you sound like how I was at you're age. You just haven't reached your growth spurt yet. When I was your age I was around 4' 5" then over the summer I grew to 5' 6" and have continued to grow. It all depends on how far you are into puberty but just be patient you will grow unless you have genes that will not make you taller. Its all about genetics.
