Good Carbs, Bad Carbs

Carbohydrates: Good Carbs, Bad Carbs

Carbohydrates: Today, “carbohydrates” are very debatable in the world, especially because of their relationship to weight loss and the popularity of low-carbohydrate diets.


One of three energy sources is carbohydrates (two other sources are proteins and fats).

Carbs are convert to glucose during the body’s metabolism. Thus, carbs provides part of the energy needed to maintain and rebuild the body during daily activities.

Why we need carbohydrates?

Energy supply


Carbs are the main source of body energy in a balanced diet, with an energy content of about 4 kilograms of energy per gram of carbohydrate.

Carbs convert to blood sugar before they are absorbed. Glucose is used by the body for the energy needed for daily activities.

Experts believe that a mix of carbs and protein can use one to three hours before exercise.

Like a combination of whole grains, peanut butter, yogurt, nuts and raisins.

Brain nutrition


Carbs are very useful for the brain activity. Brain needs Glucose which is part carbohydrates.

Supply Glucose of the body


Glucose that is overused by the body convert to glycogen in the liver and muscle.

If this glycogen not used, will become fat over longer periods.

Simple carbohydrates


These types of carbs are made up of a variety of simple, uncooked breads, pastries and pasta with white flour.

These types of carbs have a simple molecular structure and rapidly decompose and increase blood glucose levels.

That’s why it’s also harmful to people with diabetes.

Complex carbohydrates


These types of carbs are made from simple carbohydrate and need more time in the body to become glucose, and this relaxation of the nutrient degradation process is very helpful.

These types of components include whole grains, whole beans, potatoes and some vegetables.

According to the above, it can be concluded that, contrary to the opinion of some people who think that they have a better overall health and body weight, they will avoid carbs, which are the main source of energy for the body.


By replacing simple carbohydrates with complex carbs and fiber, you can have a healthier diet and prevent diseases such as obesity, diabetes, fatty liver, fatty acids, and so on.
