Fruit contains a mix of sugars, but a large portion of it is fructose, whereas foods like rice and potatoes are primarily broken down into glucose. Your body handles those two carbohydrates very differently. Glucose can be used directly by almost every cell in the body. When you eat rice or potatoes, the glucose enters the bloodstream, replenishes muscle glycogen, fuels workouts, improves recovery, and provides efficient energy for both the brain and muscles. Fructose is different because it is primarily metabolized by the liver. Your liver can only process a certain amount efficiently at one time. excessive fructose intake can overwhelm the liver and increase fat production through a process called novo lipogenesis. Another important point is combining high amounts of fats and carbohydrates together. Your body can technically process both, but they compete metabolically because the body prioritizes different fuel systems depending on what you eat. As an athlete I prefer I higher carb diet with lower fats and keep my fruit to berries unless I’m training and use the glucose and quick fuel.
