This, without a doubt, is the most common question that a Vegan is going to get asked. It's a perfectly reasonable questions as we've largely been brought up to believe that the only place to get protein is from animal products but it's a bit of a daft question so ask a Vegan this and you're likely to get a roll of the eyes and a tut...
As a little bit of background, Protein is used by your body in a number of ways. Most commonly from a fitness/working-out perspective you'll hear it being used to build and repair muscle after your session, hence why you see so many guys (and maybe gals!) walking around with a variety of protein shakes. Not only that though but Protein is involved in making enzymes and hormones, is the building block of bone, cartilage, skin and blood, in fact it's involved in every cell of your body. So pretty ruddy important.
We need 20 Amino Acids (the building blocks of Protein), 11 of which the human body can create itself by combining the various AAs together but 9 of which are 'essential' - meaning that the only way we can get them is by consuming them. Animal products are largely 'complete' meaning they have almost all AAs whereas plants largely don't.
That being said, a well planned Vegan/Plant-based diet will provide the full range of Amino Acids that a person requires. There are also a few complete sources of AAs available to us in the 'plant' world, including Quinoa, Buckwheat, Hempseeds, Chia Seeds to name a few and all of which I include in my diet regularly.
Look, there's no two ways about it. Protein is pretty bloody important! But as protein is involved at a cellular level in every living thing a Vegan will be hitting Protein requirements really easily. I often use hemp protein in a smoother as a little extra boost if I've had a particular hard workout but I've never needed to do anything additional other than that.
Just eat a wide range of fruits, veggies, beans and seeds and life is good!
