I have been vegetarian for like 7 years and get blood results every year,a nd they are always perfectly fine, also bilirubine level is good (except hormones abit low).
But my skin turns yellow often to, only my skin, not my eyes. and its a bit more around the joints, like on my hands.
don't know what it is, I don't eat much carrots, maybe 3 times a week half a carrot (because i mostly eat a lot of different vegetables a day, I make mixed dishes a lot).
I do eat a lot of vegetables thou :P like a kg a day. broccoli almost every day, same with zucchini
Also pears and apples, sharon fruit, are my favourites
Leek like 3 times a week also
