| low-calorie diet | A diet of 1,200 calories or less per day. (05 Mar 2000) |

| low-fat diet | A diet containing minimal amounts of fat.Diets containing low amounts of fat and cholesterol are designed to reduce the risk of heart disease and, in some cases, cancer. Dozens of such diets have been promulgated, both by medical and lay advisors. Their popularity can be attributed in part to clinical studies that have, since the 1980s, revealed, on the one hand, the hazards of eating high-fat, high-cholesterol foods and, on the other, the benefits of ingesting less saturated fat and LDL (low density lipoprotein) cholesterol. Although coronary deaths have been reduced by roughly 30% since 1970, the aim of health officials is to further reduce heart attack rates. The average cholesterol level among adult Americans has fallen from 213 to 205 mg/dl since 1978. However, the National Cholesterol Education Program recommends that individuals maintain a total cholesterol level of no more than 200 mg/dl, with LDL at less than 130 mg/dl and HDL (high density lipoprotein) around 60 mg/dl. About one-half of American adults exceed those recommendations. Low-fat, low-cholesterol diets are rich in whole grains, fresh fruits and vegetables, and legumes, and limit or exclude consumption of processed oils, dairy products, nuts and seeds, and meats. See atherosclerosis, free radicals. (05 Mar 2000) |
| low purine diet | A diet low in precursors of purines (such as tissues rich in cells with abundant nuclei, as in liver, glandular meats, etc.) to minimise formation of uric acid. Useful in treatment of patients with gout or urate-containing renal calculi. (05 Mar 2000) |
| low residue diet | A diet that leaves minimal unabsorbed components in the intestine, to minimise functional stress on the colon. (05 Mar 2000) |
| low salt diet | A diet with restricted amounts of sodium chloride, necessary in the treatment of some cases of hypertension, heart failure, and other syndromes characterised by fluid retention and/or oedema formation. (05 Mar 2000) |
| allantoic fluid | The fluid within the allantoic cavity. (05 Mar 2000) |
| amniotic fluid | <anatomy, obstetrics> The fluid that surrounds the developing foetus within the amniotic sac. This environment cushions the baby from injury and plays an important role in foetal development. (05 Feb 1998) |
| amniotic fluid embolism | Obstruction and constriction of pulmonary blood vessels by amniotic fluid entering the maternal circulation, causing obstetric shock. See: amniotic fluid syndrome. (05 Mar 2000) |
| amniotic fluid syndrome | <syndrome> Pulmonary embolic phenomena thought to be due to infusion of amniotic fluid containing epithelial squames into maternal blood vessels; shock ensues and sudden death may occur. (05 Mar 2000) |
| ascitic fluid | The serous fluid which accumulates in the peritoneal cavity in ascites. (12 Dec 1998) |
| blood-cerebrospinal fluid barrier | A barrier located at the tight junctions which surround and connect the cuboidal epithelial cells on the surface of the choroid plexus; capillaries and connective tissue stroma of the choroid do not represent a barrier to protein tracers or dyes. (05 Mar 2000) |
| body fluid compartments | The two phases between which water and other body fluids are distributed: extracellular and intracellular. (12 Dec 1998) |
| Brodie fluid | An aqueous salt solution used in manometers designed for testing gas evolution or uptake, as in cell respiration. (05 Mar 2000) |
| bronchoalveolar lavage fluid | Fluid obtained by washout of the alveolar compartment of the lung. It is used to assess biochemical and inflammatory changes in and effects of therapy on the interstitial lung tissue. (12 Dec 1998) |
| Callison's fluid | A diluting fluid for counting red blood cells, consisting of 1 ml of Loeffler's alkaline methylene blue, 1 ml of formalin, 10 ml of glycerol, 1 g of neutral ammonium oxalate, and 2.5 g of sodium chloride added to 90 ml of distilled water, mixed well, and permitted to stand until the solids are dissolved and the reagent is clear; the preparation is filtered prior to use.
