What are carbohydrates?
Carbohydrates are one of the macronutrients, nutrients we need in large amounts. You can read more about all the macronutrients in my discussion with Nurse Jenn.
Carbohydrates, or carbs, provide energy to the body. While the other macronutrients can also provide energy, carbs break down faster and are used as a main source of energy by some parts of our body, like the brain.
Unless you have certain health conditions, your body needs carbs in order to function at it’s best.
Types of carbohydrates
There are 3 types of carbs: sugar, starches and fiber.
Sugars are short chain carbs and can easily be broken down for energy use, so they are used up quickly.
Starches are long chains of carbs and take longer to break down. This helps with long term energy use.
Fiber cannot be broken down by the body so it passes through undigested. It helps regulates the sugar in our body. Soluble fiber dissolves in water. Things like oatmeal, nuts, beans and fruit are soluble.
Non-soluble fiber can’t be dissolved. It moves food through the digestive system and helps push it out. This is things like wheats, whole grains, brown rice, and legumes.
In foods, there are two types of carbs, simple or refined carbs and complex or whole carbs.
Simple carbs are processed to remove the natural fiber and nutrients in the food. Examples are table sugar, white bread, pastries, and fruit juices that have all the pulp taken out.
Complex carbs contain the fiber and nutrients. These are things like whole vegetables and fruits, legumes, and whole grains.
How does your body use carbohydrates?
Carbohydrates provide energy in the form of glucose. The pancreas produces insulin that carries the glucose into our cells to use as energy, then the leftover glucose in the blood is stored for later use.
If there is too much glucose build up, this raises blood glucose levels and may increase the chance of Type 2 diabetes.
Fat can also be used for energy but our bodies break down carbs faster than they break down fats, plus fats don’t break down into glucose and glucose is a preferred energy source by many parts of our body.
Weight Loss and Carbohydrates
Everyone is so different, so one approach to weight loss isn’t best for everyone. In general, when it comes to low carb diets, often the carbs that are cut are foods that are problematic anyway, such as simple carbs.
Since simple carbs break down quickly, so they spike your glucose levels which leads to a sugar high and t…
