Which food should I avoid for high triglycerides?

Question

Hello doctor,

I just got my blood work results back, and my triglycerides are at 450, which my regular doctor said is dangerously high.

I have been trying to eat healthier for the past few months, but the numbers keep increasing instead of decreasing.

I am also taking medication for high blood pressure, and I am worried about having a heart attack. So my concerns are -

Should I be on medication specifically for triglycerides, or can diet and exercise still bring these numbers down?
Are there certain foods I should completely avoid, and how often should I be getting retested?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

A triglyceride level of 450 mg/dL is definitely on the high side and can increase your risk of pancreatitis (not just heart disease). At 27, we usually see such high numbers due to genetics, diet, alcohol, or secondary issues like diabetes or hypothyroidism.

If you have already tried eating healthier and it is still rising, we need to dig deeper and be more aggressive with management.

The probable causes of the condition include a high-carbohydrate, high-sugar diet or frequent alcohol intake, genetic factors such as familial hypertriglyceridemia, and secondary causes like diabetes, hypothyroidism, or the use of certain medications.

To understand the exact cause of your high triglycerides, you will need a few tests. A repeat fasting lipid profile should be done after six to eight weeks of lifestyle changes to see how your body responds. Your doctor will also check fasting blood sugar and HbA1c, which shows your average sugar levels over three months, to rule out diabetes. Since an underactive thyroid can raise triglycerides, a thyroid profile is important. Liver function tests will help assess whether fatty liver disease is contributing to the problem.

Based on your results, this appears to be severe hypertriglyceridemia, meaning very high triglyceride levels. This can be primary (genetic) or secondary, caused by conditions like diabetes, hypothyroidism, or lifestyle factors such as diet and inactivity. Other possibilities your doctor considers include inherited cholesterol disorders and lifestyle-related lipid imbalance.

The first and most important step is lifestyle and dietary correction. You should strictly avoid refined carbohydrates like white rice, sweets, bakery items, sugary beverages, and fried foods. Alcohol should be completely avoided, as it can sharply raise triglycerides.

Increase your intake of lean proteins such as fish, eggs, and lean meats, and include plenty of fiber-rich vegetables, which help improve cholesterol levels. Regular physical activity is essential; aim for 30 to 45 minutes of brisk walking or other cardio exercises at least five days a week, based on your comfort and fitness level.

If your triglycerides remain above 500 mg/dL even after six to eight weeks of strict diet and exercise, your doctor may start medications such as Fenofibrate or omega-3 fatty acids to bring levels down quickly. If your LDL (bad cholesterol) is also high, a statin may be added. Blood pressure should be well controlled, ideally below 130/80 mmHg, using medications if needed.

Avoid binge eating and alcohol, work toward a healthy weight with a BMI below 25, stay physically active, and keep other risk factors like blood sugar and blood pressure under good control.

For follow-up, a repeat fasting lipid profile should be done after six to eight weeks of lifestyle modifications. If triglyceride levels remain high, medication should be started, and monitoring should continue every three months until the condition stabilizes.

I hope this helps.

Thank you and take care.

Regards.
