The way you eat seems very limited to me. Are you satisfied with such a narrow window of foods? I'm not an expert, but it also sounds like you're missing some of the important vitamins - namely, B12. Have you consulted a dietician on the matter?
Why limited ? there are many types of fruits and vegetables, seeds and beans. The number of combinations is huge, there are more meals I can make then meals I can't make. At first, when I started to change my life-style it was hard, but as I relearned to cook I found out that I can make more variations of food then I need to never be bored from my food. I'm doing yearly blood checks due to a medical conditions, and everything but B12 is good, so I'm taking B12 pills that you put under your tongue. The B12 issue my not be related, my close family is not vegan, not even one of them, and some of them are lacking B12 too. Not everyone can get enough B12 out of foods. What I found funny, is that people used ask about my iron and how I'm not anemic, my iron was so high on my last blood test that it was on the highest healthy value according the graph my doctor handed to me. After working out weekly for that past few years people stopped asking if I'm anemic or if I get enough protein. The only big issue is that you need to drink more water (or you will fart, a lot), which means I'm going to the toilet more.
Oh, sorry, that makes sense, Israel has a better to grew food in, from the little I know about Russian weather.
