Since I entered my 8th decade (I'm now 76) and then, 4 years ago, had bowel surgery, I have not been able to tolerate baked beans!!! And I used to really really love BB on toast - every day if wanted!
Now I can't tolerate a whole lot of things I used to love - sweetcorn, indian food, cabbage, sprouts, onions (fried or raw) and any rich foods! Bubble and squeak and cauliflower cheese are definitely wind makers, but if I make these dishes, I still have a small spoonful and then remind my husband that I've had them!
If I am going out with friends for the day or an evening, I just don't eat any of these foods for 12 hours before we all meet up!
I find it does help to have five or six small meals a day instead of the regular three. Not easy to do if you still work or are on some sort of schedule.
NfkDumpling mentioned that farts don't smell as we get older - I definitely agree with that. My husband is only 71 and I have to leave the room sometimes - Yuk!
