The main types of fibre found in our diet are soluble and insoluble fibre. Soluble fibre dissolves in water, forming a gel-like substance that can help reduce cholesterol and glucose levels. Found in oats, peas, beans, apples, citrus fruits, carrots, barley, and psyllium. Insoluble fibre does not dissolve in water and helps add bulk to the stool and appears to help food pass more quickly through the stomach and intestines. Found in whole-wheat flour, wheat bran, nuts, beans, and vegetables, such as cauliflower, green beans, and potatoes.
