Will my health suffer?!
Answers:
no reason you should suffer, otherwise Jains wouldn't exist.
Eat pumpkin for potatoes- or rice.
For the B12, eat miso, I don't believe it has bacteria in it, but is fermented using seawater. Seaweeds also have iodine and b12. Nori too.
SOybeans and tofu- stil eat them, fr the root veg, I'd just use rice, wholegrain oats, seeds and millet, quinoa istead. Lentils are pretty good, chickpeas, fava beans.
Marmite and vegemite are great things to eat. I love marmite, could eat it all day.
I think you should talk to a nutritionist. I would really miss onions and carrot juice and mushrooms. I am not a vegan but a near vegetarian as it improves the problems of Psoriasis. I have allergies to antibiotics and steroids, too
A very old hypothroid
Why are you cutting out root vegetables, mushrooms, or tempeh? Please talk to someone who knows a lot about nutrition. I never heard of this type of vegan. Can you explain more?
