Just like there are calories and calories and people and people, there are carbs and carbs. They are not all created equal. Some are healthier and some less healthy. The quality of the carbohydrate is key. Some carbohydrates are more nutritious than others. Highly processed and refined foods are often referred to as empty because most of the nutrition has been removed. They include refined sugar, white rice, and white flour products, along with other highly processed foods and alcohol—all of which can contribute to weight gain. The problem arises with using too many simple carbs in proportion to other foods you are eating: primarily fruits or too many refined processed foods in your menu. And sugars such as those found in candy, sodas, many pastries and desserts. Along with highly refined foods like pastas and white breads, these types of foods add calories but minimal nutrition. Consequently, it is wise to choose complex carbs in as natural a form as possible.
