Can alfalfa help people get taller?

No. Your height and body type depend on genetics. If your parents aren't tall, chances are you won't be either. There are always exceptions to the rule, but eating certain foods, exercising, stetching, etc. won't make you any taller. Wrong!! I grew 1 inch taller through stretching and hanging on a bar! Its hard work but it can be done. Alfalfa won't make you taller
