1) eating the same vegetables (or anything else for that matter) is never
recommendable.
variety is the key to a balanced diet.

2) you can't overdose on beta carotene when thinking of vitamin a toxicity
because it's only split to vitamin a on demand.

problems with very high beta carotene (probably not possible to reach this
level with food) however may arise if you are smoking. (see the finland
study on smokers and beta carotene)
