Carbohydrates
Carbohydrates — fiber, starches and sugars — are essential food nutrients that your body turns into glucose to give you the energy to function. Complex carbs in fruits, vegetables and whole-grain products are less likely to spike blood sugar than simple carbs (sugars). Low-carb diets like keto can be high in fats.
What are carbohydrates?
Carbohydrates (also called carbs) are a type of macronutrient found in certain foods and drinks. Sugars, starches and fiber are carbohydrates.
Other macronutrients include fat and protein. Your body needs these macronutrients to stay healthy.
How does the body process carbohydrates?
Your digestive system breaks down carbs into glucose or blood sugar. Your bloodstream absorbs glucose and uses it as energy to fuel your body.
The amount of carbs you consume affects blood sugar. Taking in a lot of carbs can raise blood sugar levels. High blood sugar (hyperglycemia) can put you at risk for diabetes. Some people who don’t consume enough carbs have low blood sugar (hypoglycemia).
What are total carbohydrates?
Foods and drinks can have three types of carbohydrates: starches, sugars and fiber. The words “total carbohydrates” on a food’s nutrient label refers to a combination of all three types.
A food’s chemical structure, and how quickly your body digests it, determine whether the food is a complex or simple carb. Complex carbs are less likely to cause spikes in blood sugar. They also contain vitamins, minerals and fiber that your body needs.
Too many simple carbs can contribute to weight gain. They can also increase your risk of diabetes, heart disease and high cholesterol
