Does coffee really stunt your growth? Examining common medical myths

The effects of coffee on your growth and the health hazard of swallowing chewing gum are just two common medical beliefs that have dogged the minds of many for years, but do they hold water?

Dr. Roshini Raj has joined Inside Edition in helping to debunk those myths.

"People used to think that coffee or caffeine may affect your risk of osteoporosis or decrease your bone growth, but that's just not true," Dr. Raj said." Coffee should not affect your growth in any way."

The doctor also takes issue with the statement that swallowed gum could linger in your digestive track for seven years.

"It's not true that gum stays in your system for seven years. It's actually digested much like the rest of the food we eat," she said.

"Cracking your knuckles, cracking your joints is perfectly fine," Dr. Raj told Inside Edition. "That actually doesn't cause any permanent or short term damage."
