How much is too much

My 22 month old will eat fruit all day if I allowed it. I don’t mind most of the time but I feel like it’s excessive. I will buy a 2 piece container of Raspberries and it’ll be gone within 2-3 days because he eats so many a day. I bought a mixed fruit container a small one, but he ate half in one day. He goes through a banana a day which is fine I guess. He also eats strawberries and will have fruit smoothies too. I know it’s probably the sugar he likes but like how do I tell him no to fruit? I’m just glad he eats something decently healthy because all he likes is beige food because he’s an extremely picky eater but fruit seems to be his go to that he never turns down. Is this normal for a toddler?
