Triglycerides

Blood-borne lipids reflecting dietary fat intake and metabolic state.

Definition

Lipids transported in the blood, mainly from diet and synthesized by the liver. Elevated levels constitute a cardiovascular risk factor.

How it works

Triglycerides are the storage form of fat in the body and circulate in the blood as lipoproteins. After a meal, their concentration temporarily increases before being used as energy or stored in adipose tissue. Elevated levels (hypertriglyceridemia) can result from excessive consumption of sugars, alcohol, or saturated fats, promoting atherosclerosis. Fasting measurement provides a reliable evaluation of this parameter.

Role

Transporting lipid energy and indicator of glucose and lipid metabolism.

Examples

  • Cooking oils
  • Butter
  • Rich cheese
  • Fatty meats
  • Ultra-processed foods
  • Sugary drinks

Recommendations

Limit saturated fats and simple sugars, favor unsaturated fatty acids (fatty fish, seed oils), and maintain regular physical activity. Normal fasting levels should be less than 150 mg/dL.

Key takeaway

Elevated triglycerides increase cardiovascular risk and are controlled by diet and exercise.
