Armpit smell like onion after switching deodorant

I recently learned deodorant with aluminum causes breast cancer so I stopped using that brand, I switched to Tom's but when I work out I smell like that ketchup, onion sundae spongebob made! Whoo wee!!! I'm literally a walking chinese restaurant leaving the gym I be so ripe! I'm not gonna switch back, I've increased the amount of water I drink and I'm eating better no meat but good grief after a work out I still stink... can anyone relate? Any remedies?
