Is it normal to often forget to eat or drink and not like food?

I usually feel like eating is a waste of time, so I forget to eat or drink if I'm not reminded or forced to. I tend to go for the entire day without eating before I realize that I haven't if nobody tells me to. I only like a few foods, sometimes even thinking of any sort of food makes me somewhat nauseous. I drink a lot of tea and water, but mostly soda.
