In a mixed triglyceride, two or even three different fatty-acid groups are present; most fats and oils contain mixed triglycerides. triglycerideAny of an important class of naturally occurring lipids, esters in which three molecules of fatty acids are linked to glycerol. The three fatty acids may be all the same kind or different kinds. The types of triglycerides in animals vary with the species and the fats in their food. In mammals they are stored in adipose tissue until needed and then broken down to the glycerol and fatty acids. Many vegetable triglycerides (oils) are liquid at room temperature, unlike those of animals, and tend to contain a greater variety of fatty acids. In alkali, triglycerides break down to form glycerol and three molecules of soap (saponification). |

| Along these lines, a pilot study conducted in HIV-positive patients with lipodystrophy assessing the combination of dietary and exercise counseling with or without fish oil (omega-3 fatty acid) supplementation reported a significant decline in triglyceride levels at week 4 in patients receiving fish oil, that was no longer significant at week 16. Compared with the higher carbohydrate diet, the higher protein diet further decreased blood pressure, LDL cholesterol, and triglycerides and lowered HDL (good) cholesterol. In a recent study, people who ate to three kiwifruits daily for 28 days reduced their platelet aggregation response (potential for blood-clot formation) 18 percent and their blood triglyceride (fat) levels by 15 percent compared with people who ate no kiwi. |
