Fresh pears and fresh raspberries are super high natural fiber foods with 8 grams per serving, (unsweetened). If they are frozen, they loss much of the fiber, down to only 2 grams for the raspberries.

Dairy can create that problem for many. I think someone mentioned that above. I use the Fiber One from General Mills that provides 51% of a daily recommendation and that doesn't really get me 'moving' the best.

Are you getting soluable and insoluable fiber? That's the key. Old fashioned Oatmeal or steel cut Oatmeal are the ones that need longer cooking because they are more dense, so they "scrub" your insides better! Plus Oatmeal is low fat, no sodium and with the pear chunked up in it, you don't need to add a sweetener! I can even eat it without butter or at least only a tiny 1/2 teaspoon or sometimes I go wild and use a whole teaspoonful!

Pears baby, I'm telling you. They really work for me.

If you don't have to worry about sugar (diabetic?) too much try eatting 1 large pear and oatmeal for a few days. That has been helping me a lot. Prunes don't help nor does all the Miralax, stool softeners, and fiber supplements that I take every day, with doctors orders to do so. Some of us are just more prone to being constipated than others.

Exercise helps too. And when I drink coffee with caffiene, I try to drink equal amounts of plain water.

FiberCon pills work the best of all I've tried. I saw an article in a magazine that compared the top selling fiber supplements and that was the brand shown to work the best. I agree.
