Is soy included in your nut allergy? I'm vegan and don't eat many nuts, although most of my protein comes from soy products. I was vegetarian for a while and used whole milk, eggs, and cheese for protein. Although I believe in the rights of living creatures so I couldn't do the dairy/eggs route any more.
There are plenty of foods that will give you enough protein, leafy greens like kale, beans, and rice are a staple of any stir fry/curry and are complete meals nutritionally.
fwiw, one of the things i love about my diet that was really hard to get used to was the difference of caloric density of vegetables vs animal products. I am constantly full and sometimes just have a hard time stuffing my face with enough food. I also am an amateur athlete so my caloric needs are probably really different than most people on this site.
>Also, would you listen to my argument about how individual red meat consumption is a drop in the bucket of climate change and isn't really worth focusing on?
I don't believe we're going to be able to change big business if we don't have the gumption to change our day to day lives. We need to live it in order to make real change, and factory farming, specifically of red meat, is the highest on the list for personal consumption. I also believe we've advanced as a society to not have to rely on killing living beings or manipulating their reproductives cycles for our benefit.
edit: I don't understand the downvotes here. I am literally informing someone about MY diet. Can you please add a response if you choose to downvote this post.
