I don't know why this is getting downvoted when it seems like a valid question to ask someone who does not eat any vegetables. Vitamin deficiencies can develop subtly into extremely serious problems. I have a condition that means I am more prone to them and, after having had mild scurvy, a vitamin D deficiency, a copper deficiency, a selenium deficiency, and many others, I would not wish them on my worst enemy. Most of the symptoms are basically not noticable, and develop so slowly that you don't realise them and tend to just get used to it, but they can cause A Lot Of Problems. Most of the main sources come from vegetables.
