Less sugar text from tiled letter blocks and sugar pile on a spoon suggesting dieting concept

Definition

Simple sugars and refined carbohydrates offer quick but fleeting energy. They lack fiber, vitamins, and minerals making them “empty” sources of calories.

Explanation

  • Simple sugars like sucrose, fructose, glucose and dextrose spike blood sugar and insulin rapidly due to fast absorption and digestion.
  • Refined carbs including white bread, crackers, pastries and breakfast cereals provide easily accessible energy but minimal satiety or nutrition.
  • Limit added sugar and processed refined grains. Instead, choose whole foods with fiber like fruit, beans, minimally processed whole grains and starchy vegetables.
  • If cutting out simple sugars entirely, reduce gradually. Moderation is key for long-term sustainable nutrition habits.

Examples

  • Candy, soda, table sugar, agave nectar, maple syrup
  • Donuts, saltine crackers, instant potatoes, white rice

Related Terms
