What Are Carbohydrates? Benefits, Functions & Best Sources

Carbohydrates are one of the three macronutrients that our body needs to function. The other two are protein and fat. Carbohydrates can be found in a variety of different foods, including grains, fruits, vegetables, legumes, and dairy products. They are an important source of energy for our bodies and play a role in cell growth and function. Carbohydrates are classified into two categories: simple and complex.

The first type are made up of 1-2 sugar molecules, while three or more sugar molecules  combine to form complex carbohydrates. Complex carbohydrates are a better source of energy for our bodies because they take longer to digest than simple carbohydrates. The following are the top sources of both simple and complex carbohydrates.


  • Broccoli
  • Bell peppers
  • Pumpkin


  • Bananas
  • Mango
  • Apple


  • Chickpees
  • Kidney beans
  • Lentils

1Health benefits of carbohyrates

When most people think about the health benefits of carbohydrates, they think about weight loss. While it is true that carbohydrates are an important part of a healthy diet for weight loss, there are many other health benefits of carbohydrates. Carbohydrates provide your body with energy, help you regulate blood sugar levels, and can even improve your mood. The following are the most effective and well-studied health benefits of cabohydrates

Fuel for brain

When you eat foods rich in carbohydrates, your body breaks them down into glucose, which is absorbed into the bloodstream. Glucose is the brain’s main source of energy, and it needs a steady supply to function optimally. When blood sugar levels drop too low, the brain starts to slow down and you may feel tired or fuzzyheaded.

Carbohydrates are important for cognitive function because they help keep blood sugar levels stable. In fact, research has shown that people who consume a lot of carbs tend to be smarter than those who don’t. This may be because carbs help protect against age-related decline in memory and learning ability.
