Triglycerides are a type of fat found in the blood. They are used to give energy to the body, and any extras are stored in different places in case they are needed later. Triglycerides come from foods, especially butter, oils, and other fats you eat, and also from extra calories your body does not need. A high level of triglycerides has been linked to a greater chance for heart disease.

The guidelines for fasting triglyceride levels in adults are:

• Low: below 150 milligrams per deciliter (mg/dL)
• Borderline high: between 150 and 199 mg/dL
• High: between 200 and 499 mg/dL
• Very high: 500 mg/dL or higher

To lower triglyceride levels, one can follow these steps:

• Lose excess body fat using a combination of healthy eating and regular exercise
• Avoid high sugar foods such as lollies and choose foods with a low glycemic index such as legumes and wholegrain products
• Eat more fish, especially those rich in omega-3 fatty acids such as salmon, mackerel, tuna, and trout
• Cut back on alcohol
• Don’t smoke

It is important to note that a blood test can reveal whether or not you have high triglycerides, and you may need to have two or more blood tests for accurate results. It is recommended to fast for at least 12 hours before each blood test because food, particularly fatty food, can temporarily boost triglyceride levels in the blood and skew your test results.
