Carbs is a shortened term for carbohydrates. Carbohydrates are one of the three main macronutrients, along with proteins and fats, that our bodies need to function properly. They provide energy in the form of calories and can be found in many foods such as bread, pasta, rice, fruits, vegetables, and dairy products. The body breaks down carbohydrates into glucose, which is then used by cells for energy or stored for later use.
