Laxatives vary based on how they work and the side effects they have. Certain stimulant, lubricant and saline laxatives are used to evacuate the colon for rectal and bowel examinations, and may be supplemented by enemas under certain circumstances. Sufficiently high doses of laxatives may cause diarrhea.
Most vegetables, with the exception of onions, mushrooms and tomatoes, should be blanched briefly before being dehydrated to limit discoloration and the risk of food-borne illnesses. You can dehydrate tomatoes, carrots, beets, greens, beans, squash, onions, peas, celery, corn, pumpkin and broccoli with good results.
I had the same problem for awhile to the point ...Once the dehydration was under control, I was able to eat a little more - basic foods like chicken, plain hamburger or steak, baked potato, bananas.....
