| high extinction microscopy | <technique> Polarized-light, interference, fluorescence, and other modes of microscopy using polarization rectifiers and other devices to achieve a high degree of back- ground extinction in order to bring out the signal originating from a very small degree of birefringence, optical path difference, fluorescence etc. (05 Aug 1998) |
| high-fat diet | A diet containing large amounts of fat. (05 Mar 2000) |
| high-fibre diet | A diet high in the nondigestible part of plants, which is fibre. Fibre is found in fruits, vegetables, whole grains, and legumes. Insoluble fibre increases stool bulk, decreases transit time of food in the bowel, and decreases constipation and the risk of colon cancer. Soluble fibre delays absorption of glucose, which helps to control blood sugar in diabetes mellitus, and delays absorption of lipids, which helps to control hyperlipidemia. Recommended in treatment of diverticular disease of the colon. (05 Mar 2000) |
