Not IBS but i am bloated daily

To whom can help,

I am 29 male...healthy, eat well, have controlled my diet, avoided a lot of foods and all the advice i could find but I havent gotten much relief. My bloating is not severe but is visable. I was wondering if excess saliva causes me to swallow more often and in turn taking in too much air to my stomach. If I sit for 5 minsutes without spitting or swallowing my mouth fills with saliva. Is this normal, could this cause bloating?
