Triglycerides are a type of fat found in your blood derived from excess calories, sugar and alcohol consumption that contribute to heart disease at high levels.


  • Triglycerides come primarily from liver production and diet. Levels above 150 mg/dL indicate higher heart disease risk.
  • They circulate in blood until deposited into fat cells for storage. Excess intake surpasses fat storage capacity, elevating triglycerides.
  • High triglycerides correlate with obesity, insulin resistance, metabolic syndrome and cardiovascular disease. They lower HDL cholesterol.
  • A low carb diet, omega-3s, exercise, weight loss, limiting alcohol and certain medications help lower triglyceride levels.


  • Correcting a triglyceride level of 250 mg/dL through diet and exercise changes.
  • Keeping triglycerides under 100 mg/dL with a Mediterranean style low sugar diet.
