I would say that if you have persistent bloating, then it is worthwhile speaking to your gp. This can be indicative of other things and depending on your age, it may be prudent to discuss this with your GP. One of the symptoms of cysts on the ovaries can be bloating, so if in doubt please check it out! I have just experienced this and a liver ultrasound has also found a cyst on my right ovary and now I am facing more tests and surgery. I had no other symptoms other than bloating, so hopefully yours is food related, but always check.
