'Leaves are an excellent source of healthy fibre. Lack of fibre (usually due to a diet of processed foods and animal products) causes pain, constipation and disease. Adequate fibre results in regular soft stools and health. The fibre in leaves is particularly beneficial and much healthier than excessive amounts of bran (from wheat) which can act as an intestinal irritant. In fact the fibre present in fresh raw leaves encourages the "friendly" lactobacteria - mainly Lactobacillus acidophillus in the intestines to proliferate and grow there. These bacteria thrive on green stuff. Inside us they make B vitamins (including B12) and vitamin K.'
