There seems to be so much controversy around carbohydrates. How much do we really need? What’s the ratio for a healthy diet? Can we actually take in too little? How much is too much? Do they make us fat?
Depending on where the information is coming from you will get various answers BUT little of it seems to stems from any real hard evidence or truth. Most of the speculation or information about carbohydrates is just old, out-dated, and IMO just wrong.
So, I am going to debunk the myth and set the record straight once and for all.
First, the lower limit of dietary carbohydrates compatible to sustain life is ZERO provided adequate amounts of protein and fat is consumed.
To prove this fact, look up the term essential protein. You will find there is a list of 20 amino acids 10 of which are essential “MEANING” you absolutely must get them from your diet or your body will break down. (1)
Then look up the term essential fat. You will find that there are two fatty acids you absolutely must get from your diet or your body won’t function properly. (2)
Now try to look up the term essential carbohydrate. You will be amazed to know that there is NO SUCH THING. You’ve heard me correct, carbohydrates are not essential to our survival.
Now don’t misunderstand me, I said “CARBOHYDRATES” not “GLUCOSE”. You see, we are lead to believe that we need carbohydrates for energy ‘especially brain function’. The fact is, the brain runs on about 120 grams of glucose per/day to function and operate BUT it’s a huge misconception that we need to get that supply from dietary carbohydrates.
Our body has the amazing ability to convert fatty acids or certain glucogenic amino acids to glucose through a process called Gluconeogenesis or (GNG). SO, even on a diet made up of ZERO carbohydrates “which I am not advocating at all” our body would still produce plenty of glucose to meet the brains energy demands. (3)
Look, I agree, some carbohydrates in our diet are healthy (especially vegetable based) or (low glycemic fruits and starches in proportionate amounts), but not 40 to 60 percent deriving mostly from sources like breads, cereals, rice, and pasta.
So, let’s ask ourselves why we put such a HUGE emphasis on, as well as grossly over-consume, the one food that our body requires no physiological need?
