High Intake of Refined Carbohydrates Increases Triglyceride Levels: Consuming a diet high in refined carbohydrates, such as white bread, pastries, and sugary beverages, can lead to an increase in triglyceride levels. When the body digests these refined carbs, they are quickly converted into glucose, which can cause a spike in blood sugar levels. In response, the body releases insulin to help cells absorb the glucose. Excess glucose that is not used for energy is converted into triglycerides and stored as fat. Over time, consistently high levels of refined carbohydrate intake can lead to elevated triglyceride levels, increasing the risk of cardiovascular disease.
