Broccoli also helped reduce my Hpylori problem, although so have several other things. Broccoli worked in the same day for me too. BUT if you really cook it for a long time, it doesn't help. Just boil it really quick to get rid of any bacteria it may harbor (you never know what the people picking it are like). It should be BRIGHT NEON-ISH GREEN when you eat it. Don't boil or steam for over two minutes. In most cases 30seconds to a minute is just fine, maybe even less than that is needed. It should still be CRUNCHY when you eat it as well. If it is cooked to much it will not help you at all.
