WHY do we NEED Carbohydrates?

on November 6, 2013

I just made my first 100%!!! My FNS classes are moving s-l-o-w-l-y along and I’m passing w/ a 90% avg but today on the CARBOHYDRATES test I scored 100!!! WooHoo~ Sooo…let’s talk a lil’ about carbs WE DO NEED SOME CARBS IN OUR DIETS!! I’ve said before that though we are limiting our carb intake we are not to ELIMINATE them! Eliminating carbs completely will put our bodies into KETOSIS (Abnormally high concentration of ketone bodies in body tissues and fluids.)
The body needs a MINIMUM of 50 to 100 grams of carbohydrate daily. The body needs some (complex) carbohydrates to completely break down fat and prevent the buildup of ketone bodies in the blood. Notice I said MINIMUM; on a 2000 cal/day diet an acceptable range would be 225-325g; this is considered to be on the HIGH side for those of us striving to lose rather than maintain. A good rule of thumb is to consume under 30g (no more than 45g) w/ each meal…keeping in mind that you’re eating every 2.5-3 hours
“In the absence of carbohydrate, both proteins and fats can be used for energy. Although most cells can break down fat for energy, brain cells and developing red blood cells require a constant supply of glucose. (After an extended period of starvation, the brain adapts and is able to use ketones from fat breakdown for part of its energy needs.) If glycogen stores are depleted and glucose is not provided in the diet, the body must make its own glucose from protein to maintain blood levels and supply glucose to the brain. Adequate consumption of dietary carbohydrate spares body proteins from being broken down and used to make glucose. Even when fat provides the fuel for cells, cells require a small amount of carbohydrate to completely break down fat to release energy. When no carbohydrate is available, the liver cannot break down fat completely. Instead, it produces small compounds called ketone bodies. Most cells can use ketone bodies for energy.
When ketone bodies are produced more quickly than the body can use them, ketone levels build up in the blood and can cause a condition known as ketosis. People vulnerable to ketosis include those who consume only small amounts of carbohydrate or who cannot metabolize blood glucose normally. Ketosis is most commonly caused by very low carbohydrate diets, starvation, uncontrolled diabetes mellitus, and chronic alcoholism. Ketosis also can develop when fluid intake is too low to allow the kidneys to excrete excess ketone bodies. As the concentration of ketone bodies increases, the blood becomes too acidic. The body loses water as it excretes excess ketones in urine, and dehydration is a common consequence of ketosis.”
Chalk that up to just one more reason why we need to increase water intake to that of feeling that our eyeballs are continuously floating 😉
I ain’t gonna lie…I’M FEELING SMART (teehee)
