What Are Carbohydrates Used For In Our Bodies?
What are the carbohydrates used for in our body?
Carbs are varied. There are complex carbohydrates that are absorbed slowly and you hardly get an insulin reaction. On the other end of the spectrum there are refined carbs like sugar, which are rapidly absorbed in the gut and to which the body reacts swiftly with an insulin reaction to lower high blood sugars.
Generally speaking all carbs are broken down into glucose and absorbed in the gut. Glucose is the fuel that is metabolized inside the cells in the mitochondria to give us energy. This is particularly important in the brain, which lives solely by glucose as its energy supply, but our muscles, our heart, our liver, and kidneys are all very rich in mitochondria for the metabolism of glucose.
But there is a dark side to refined carbs that we need to know about: When all our glucose storage spaces in the liver and the muscles are full (glycogen is the storage form of glucose), then the liver starts processing glucose. With our sugar consumption having spiraled upwards in the last 183 years, this surplus sugar metabolism is causing more and more problems.
The liver produces triglycerides from the extra sugar and LDL cholesterol, the bad cholesterol. This causes hardening of the arteries and causes heart attacks, strokes, and high blood pressure.
We need to come to our senses and cut out processed foods (which have extra sugar in them), switch to a Mediterranean diet and only consume complex carbs, contained in legumes, vegetables, and fruit. It is also recommendable to cut out starchy foods with a glycemic index of higher than 55 in order to bring our liver metabolism back to normal (normal triglyceride and LDL cholesterol production). This will mean cutting out pasta, potatoes, rice, bread, and muffins.
