Lowering triglyceride levels can require a change in dietary and lifestyle habits. If these steps are implemented, then it is possible for some people to see lower triglyceride levels in a matter of a few days, according to the University of Massachusetts Medical School.
Although triglycerides are important in the body for energy, a high triglyceride count may increase the risk for heart disease, according to Mayo Clinic. The normal level of triglyceride, which is a type of fat, should be less than 150 milligrams per deciliter.
When triglyceride levels are high, the American Heart Association recommends lowering these levels by changes in diet and lifestyle habits, notes Mayo Clinic. Foods that contain excess sugar, refined carbohydrates and fats should be eliminated from the diet. Foods to eat, which can lower these levels, include tuna, salmon, beans, oat bran, fruits, vegetables and whole grains. Changes in lifestyle habits can entail losing weight, exercising and not consuming alcohol.
