High-Calorie Foods
Foods that contain high amounts of calories are known to increase triglyceride levels. While some high-calorie foods [9] such as avocados and nuts may have high nutritional value, it is important to contact your doctor for advice and extra guidance.
Donuts
Everyone loves donuts, except the bloodstream. Studies show that donuts contain high levels of sugar which can result in an increase in triglycerides level in the blood. The body processes glucose and converts it into fats. It would help to completely stay away or reduce your intake of donuts.
