Limiting nutrients is never the way when it comes to being healthy. If you think you're being healthy by eliminating foods, you are mistaken!
Eating a balance from all food groups is what healthy eating is about! You are making yourself sick and weakening your immune system by restricting yourself!
You would also develop really bad cravings towards foods you cut out.
Dieting and missing foods doesn't teach you to get sustainable longterm results! It's just a gimmick for short term gain with health consequences.
