Isolated fiber: Cereal, crackers, bread, muffins.
When a food ingredient contains the word "fiber," it's code for an isolated fiber. "Wheat fiber" and "oat hull fiber" are insoluble fibers, which may help prevent constipation but don't lower blood cholesterol or blood sugar. "Oat fiber" can be either insoluble or soluble fiber. Soluble fiber may lower blood cholesterol and blood sugar but doesn't prevent constipation. Finally, isolated fibers don't contain the micronutrients and phytochemicals that foods with naturally occuring fiber contain.
