Are food stamps a bad thing?

My grandparents are making me go on food stamps and I am extremely frustrated about it! I do not want nor do I myself need to go on food stamps. I know they're just making me go on it for themselves. I buy all of my own food because I'm a very picky eater and I don't eat or like the same foods as them. Eggs and rice are probably the only foods of theirs I actually eat. I am not okay with this in the slightest! Can't they get their own food stamps? And would me going on food stamps affect me in any negative ways? Long term and short term? Whenever I go to fill out online job applications they always ask about things like food stamps. Will this hinder me when it comes to applying to jobs?
