Wheat bran is an insoluble fiber.
This fiber helps move waste through our digestive tracts, helping prevent constipation, but is also not digested. With all the power failures and brownouts, I'm concerned about which foods in my refrigerator I can eat and which ones I should throw away. In the event of a power failure, place the freezer packs next to the most perishable foods in the refrigerator compartment, and keep the refrigerator and freezer doors otherwise closed. Frozen foods, if the door remains closed, can safely last a day or two. Fresh fruits and vegetables, hard and processed cheeses, condiments and butter will usually last up to five hours at room temperature.
