High blood triglyceride levels can be lowered by reducing the intake of carbohydrates, fats and alcohol, reports Everyday Health. However, calories need to be restricted as well, as any excess calories are automatically converted to fat by the body.
An obvious dietary change to reduce blood triglyceride levels is to reduce fat intake, according to Everyday Health. Specifically, saturated and trans fats must be eliminated from the diet, which are common in fast foods and animal products. A daily limit of 200 milligrams of cholesterol is recommended. Unsaturated fats such as olive or vegetable oils may be substituted for these fat sources. Alcohol must be avoided, as it is essentially a non-nutritious source of carbohydrates and only adds to triglyceride levels. Likewise, any added or refined sugars should be cut from the diet.
Foods such as fruits, vegetables, and low or nonfat dairy products are recommended by Everyday Health to fight high triglycerides. High-fiber foods should be emphasized, as these foods fill up the stomach before excessive amounts of calories can be consumed. Fish is recommended as a protein source and should be eaten twice a week if possible. Fish contain higher levels of omega-3 fatty acids, which aid in the reduction of triglyceride levels. Despite undergoing these dietary changes, an individual may still require medication to successfully manage his triglyceride level.
