Highly depends on what you're trying to skill up. Yes the foods make a noticeable difference if you use them correctly, however people have neither qualified exactly how they work nor quantified how much they actually increase skill up rate. Use your own discretion.
Any particular reason you want to skill up outside of Abyssea, anyway? I find that you can just toss on regen atmas and basically do it while watching Youtube, it's nice.
