There's a certain line in pumping iron that makes me laugh, it's said by Arnold himself...you may have an idea what i'm talking about, i say no more here lol
Haha, but seriously, those things can be eaten in small-moderate amounts and do no harm. It's only when people binge that it gets dangerous. IMO anyway.
Food is a baraka. Alhamdulilah. So it cant be 'bad' per say. As long as you exercise, use your common sense and take it moderation, (something which Islam preaches, anyhow) then there's really nothing to worry about.
