Protein for Vegans and Vegetarians

[mill]

I have yet to post on bring4th before now.. but this is a topic I was felt compelled to input on having stopped eating meat recently .. I do my best to avoid all animal products but currently battling a love for cheese!

Anyway my boyfriend got me an alkaline food book last year and in there I read about grains such as Amaranth Quinoa and Spelt. In the book it says 'Using Amaranth in combination with Quiona and Spelt results in a complete protein as high in food value as fish, red meat of poultry.'

I havent looked into it much more than the reading in this book but I did go down to a local health food shop and buy all three cant say I feel like i'm missing anything from my diet but I have been wanting to get on the super green smoothies for a while now and after reading this I know I must!

Anyone know any more about these are sources of protein?
