Protein or monounsaturated fats are good replacements for saturated fat.We've all heard that it's important to reduce the amount of saturated fat saturated fat, any solid fat that is an ester of glycerol and a saturated fatty acid. The molecules of a saturated fat have only single bonds between carbon atoms; if double bonds are present in the fatty acid portion of the molecule, the fat is said to be unsaturated 1. not holding all of a solute which can be held in solution by the solvent. 2. denoting compounds in which two or more atoms are united by double or triple bonds. un·sat·u·rat·ed (. Unsaturated fats unsaturated fat: see saturated fat. generally have lower melting points than saturated fats and are often liquids (oils) at room temperature. in our diets. What's less certain is which nutrient should replace saturated fat. Should we be eating more protein, more carbohydrate, or more unsaturated fat? A recent study tried replacing saturated fat with either protein (2/3 plant protein and 1/3 animal protein), carbohydrate, or monounsaturated monounsaturated /mono·un·sat·u·rat·ed/ (mon?o-un-sach´er-at?ed) of a chemical compound, containing one double or triple bond. mon·o·un·sat·u·rat·ed (m  n fat (canola and olive oil, nuts and seeds) and then determining the effect of this on blood pressure and LDL LDL - Low Density Lipoprotein (so-called 'bad' cholesterol)LDL - Lightwave Data Links (AT&T) LDL - Linux Distribution List LDL - Litho Density Log (Oil Industry) LDL - Loudness Discomfort Level (audiology) LDL - Low Density Level (asset supply management) LDL - Low Density Protein LDL - Lower Detection Limit LDL - Lower Deviation Level (bad) cholesterol. Study participants were 164 adults with mildly elevated blood pressure blood pressure, force exerted by the blood upon the walls of the arteries. The pressure in the arteries originates in the pumping action of the heart, and pressure waves can be felt at the wrist and at other points where arteries lie near the surface of the body (see pulse). Since the heart can pump blood into the large arteries more quickly than it can be absorbed and released by the tiny arterioles and capillaries, considerable inner pressure always exists in. They were on each diet for six weeks. All diets were low in cholesterol and sodium and high in fruits and vegetables. Blood pressure and total, LDL, and HDL cholesterol decreased on all three diets. Compared with the higher carbohydrate diet, the higher protein diet further decreased blood pressure, LDL cholesterol, and triglycerides triglyceride /tri·glyc·er·ide/ (-glis´er-id) a compound consisting of three molecules of fatty acid esterified to glycerol; a neutral fat that is the usual storage form of lipids in animals. tri·glyc·er·ide (tr and lowered HDL (good) cholesterol. The higher unsaturated fat diet also further decreased blood pressure and triglycerides but did not decrease LDL cholesterol. HDL cholesterol was higher on the high unsaturated fat diet. All three diets lowered the risk of heart disease, with higher protein and higher unsaturated fat diets having a greater effect than higher carbohydrates. This study suggests that, for those with high blood pressure, a somewhat higher protein intake (with at least half from plant sources) or a somewhat higher intake of unsaturated fat, along with low sodium intake and generous amounts of fruits and vegetables, can help to reduce blood pressure and may lead to lower cholesterol levels and a reduced risk of heart disease.
