What are carbohydrates?

According to Dictionary.com, the definition of a carbohydrate is:

“any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones, or change to such substances on simple chemical transformations, as hydrolysis, oxidation, or reduction, and that form the supporting tissues of plants and are important food for animals and people”

Simple as that! Right?

Actually not! Unless you are some sort of highly academic bio-chemist or scientist, this definition means absolutely nothing.

On a more serious side, carbohydrates, commonly referred to as carbs, are sugars, fibers, and starches derived from food groups including fruit and vegetables, grains, and dairy products, which supply energy to the body.

They make up one of the three macronutrients or macros, which also include fat and protein, and are essential to the proper functioning of the body.

These macros cannot be produced by the body and must be acquired through foods.

Because carbohydrate ultimately turn to sugar, there is a common misconception that all carbs are bad.

Carbohydrates, as we mentioned above are essential for a proper functioning body, and can be broken into 2 categories, good carbs and bad carbs.

Good carbs, or complex carbohydrates are generally derived from whole grains, fruits, vegetables, beans and legumes, while bad carbs generally come from low nutrient foods like cakes and cookies, sodas, processed foods such as white bread and white rice, and pastas.

The properties of good carbs are:

  • Low calorie count
  • High nutrient value
  • No processed sugars or grains
  • Contains natural fiber
  • Low in sodium
  • Limited saturated fat
  • Low in cholesterol
  • No trans fats

The properties of bad carbs are:

  • High caloric count
  • Contains refined sugars
  • Contains processed grains
  • Very few if any nutrients
  • Low in fiber, high sodium
  • High in saturated fat, trans fat, and cholesterol

You can use this list of good carbs versus bad carbs to determine where your eating patterns fit and adjust your diet accordingly.
