Yes as long as your doctor says it's okay you can still eat regular food with a feeding tube.
Some people who have feeding tubes are unable to eat any regular food or get any other drinks and fluids down them so they get dehydrated and malnourished.
But if you're able to still eat regular food and have a feeding tube to help with the nutrition and hydration of your body then you certainly can eat some regular food when you have a feeding tube.
My Grandpa had a feeding tube and he eventually started eating some regular foods which was a good thing as it helped him to get healthier.
Then eventually he was able to stop using the feeding tube.
Speak with your doctor first though to see if they approve of you eating regular food at this time when you have the feeding tube in.
But most times it's okay to eat some regular food with the feeding tube.
