How is it unhealthy?
There are some vitamins that you can not get from non-animal sources, if you're not supplementing. You'll have to get somewhat creative to get some other nutrients in adequate amounts. The good news is that most of the deficiencies won't show up for a LONG time. You DO have to be careful that you're getting all the amino acids you're going to need. The body really is an amazing thing, but it wasn't blessed with the ability to make all the amino acids it needs.Not everyone will do it intelligently and meet all their nutritional needs and wont buy supplements which can screw you up all over the place.
