Why is my parents so nosey? like overprotective much?

Vicky grew up with many pets and has a profound love of animals. at the age of 20, she sees a documentary on the internet that showed how domestic animals such as cows, pigs, and chickens are raised for the purpose of slaughter. the footage and information deeply disturb her, so she declares herself a vegetarian; she doesn’t feel right about eating meat anymore. after investigating the matter a little more, vicky decides that being a lacto-ovo vegetarian is the best fit because she wants to keep consuming dairy products and eggs. vicky is a little concerned about getting enough protein and essential amino acids from her diet because she’s quite active and plays college volleyball. do you think that vicky can reasonably get enough protein from her new diet, considering she stands 5 feet 11 inches tall and weighs 155 pounds
