"My mom thinks im not getting enough protein?"
Your mom may well be wrong, about whether you're getting enough protein. However the self declared has declared science as wrong where nutrition and protein is concerned. In fact they think that they can shame any nutritional scientist in overall knowledge, and any nutritional researcher that says otherwise, is wrong because they say so. Plant based foods can in fact meet all of the protein needs a person has. This has been backed by nutritional research that predates PETA, by about seventy years and even veganism by more than fourty years.
As someone whose diet does have meat in it, I will take science what science says over those who prefer to use incomplete science. There are nine essential amino acids that are required to make what we know as a complete protein chain. However those amino acids don't have to be singular dietary based. They can some from a multitude of sources. Also science has shown, that the body will often breakdown what's known as complete protein, and store it in the forms of the nine essential amino acids, and will make whatever protein chain is needed, for whatever specific protein need the body has.
What I use as sources for nutrition, comes from the top research facilities, and will disagree with what some vegans, some vegetarians, and especially PETA puts out. I do NOT cherry pick data, as some do, and love to do, to back their beliefs. I am NOT a dietitian, nutritionist, or any other type of medical professional. Nor am I as some that like myself whose diet does have meant and other animal based foods in it, a self declared expert or guru, on diet and nutrition.The truth is there aren't any in here that qualify as such, although there are some would have one believe otherwise.A few of us though has actual knowledge of nutrition, and whether we eat meat or not, becomes irrelevant, as we'll prefer facts over supposition, and personal biased opinion.
The advice of talking with a nutritionist is the best given though. However it should be from someone that's actually a licensed medical dietitian. Yes doctors can be helpful, but usually most has no more than one or two semesters of nutrition behind them. A few however will take a few more semesters to be more knowledgeable about nutrition. A good nutritionist will also want to see a food log or food diary, of what you've eaten, to assess, where and what shortfalls you have, and then advise you on what you need to do to correct those shortfalls.
