Of course, all bets are off when you have diverticulitis. Adding more fiber to the diet would exacerbate the situation and most folks over age 60 have this problem. Most everyone on this forum is over age 60.

Now, if you began a high fiber diet when you were relatively young, the chances of developing diverticulitis decreases dramatically. However, if you have ever had problems with constipation during your older years, you most likely have developed diverticuli in your colon and things such as nuts, most fruits, etc... will produce adverse effects.

Good luck,
