These studies suggest that reducing processed foods, increasing fruits, vegetables, nuts, fish oils, and omega-3 fatty acids, and incorporating specific ingredients like enriched-conglycinin soybean, soluble fiber, and inulin can help reduce triglyceride levels.

Elevated triglyceride levels are a significant risk factor for cardiovascular diseases and other chronic conditions. Various dietary strategies have been identified to help reduce triglycerides effectively. This article synthesizes the latest research on foods and dietary components that can lower triglyceride levels.
Fish and fish oils are rich in omega-3 fatty acids, which have been shown to significantly reduce triglyceride levels. Studies indicate that incorporating fish oil into the diet can lead to substantial decreases in plasma triglycerides, with reductions as high as 64% in hypertriglyceridemic patients . Additionally, consuming 80 grams per day of omega-3-rich fish can decrease triglycerides by 8.2%. Chronic intake of fish oil also reduces postprandial triglyceride levels, suggesting its effectiveness in both fasting and non-fasting states.
Increasing the intake of fruits, vegetables, and nuts is another effective strategy. A dietary model showed that reducing processed foods by 50% while increasing the intake of fruits (75-225 g/day), vegetables (75-225 g/day), and nuts (10-40 g/day) can decrease triglycerides by up to 4.3%. These minimally processed foods are rich in fiber and essential nutrients that contribute to lipid metabolism.
Soybean products, particularly those enriched with β-conglycinin, have been found to improve lipid metabolism and reduce triglyceride levels. A study demonstrated that consuming β-conglycinin-rich soybean significantly decreased triglyceride levels in adults, especially in those with baseline triglyceride levels of 100 mg/dL or higher.
Cacao by-products have also shown promise in reducing triglycerides. In a study involving overweight subjects, the consumption of cacao by-products, combined with a reduced-calorie diet and aerobic exercise, led to a significant reduction in triglyceride levels by 27.9%. This suggests that cacao by-products could be a beneficial addition to dietary interventions aimed at lowering triglycerides.
Inulin, a type of nondigestible carbohydrate, has been shown to reduce hepatic lipogenesis and plasma triglyceride concentrations when added to a high-carbohydrate, low-fat diet. Similarly, soluble fiber has been noted to lower postprandial triglyceride responses, making it a valuable component in managing triglyceride levels.
Adhering to a Mediterranean diet, which emphasizes the consumption of fruits, vegetables, whole grains, low-fat dairy, and fish or other omega-3 fatty acids, is strongly recommended. This diet not only lowers triglycerides but also reduces cardiovascular disease risk and overall mortality.
Incorporating specific foods and dietary components such as omega-3 fatty acids from fish, fruits, vegetables, nuts, soybean products, cacao by-products, and soluble fiber can effectively reduce triglyceride levels. Adopting a Mediterranean diet further enhances these benefits, contributing to better cardiovascular health and reduced chronic disease risk.
