Carbs: All are not Bad

When the humans were evolving they didn’t know the art of agriculture. So they didn’t know to grow the edible plants. At this stage their diet was obtained from killing the animas. Thus their diet consisted mainly of fats and proteins. When agriculture was established, then humans added the carbohydrates into their food menu.

Carbs or Carbohydrates have become much maligned food from sometime. Many people say they are not good for health. These are mostly sugars. Sugars they say lead to diabetes, obesity and tooth decay.

Carbohydrates are one of the three essential categories of food along with fats and proteins. Carbohydrates provide energy to the body, fats also provide energy and fat and proteins build the bony structure of the body.

What are the carbohydrates?

Chemically carbohydrates are compounds made from Carbon, hydrogen and oxygen. There are many categories of the carbohydrates. Carbohydrates are synthesized in nature by plants and trees by a process called photosynthesis. This way they convert carbon dioxide and water into Glucose which is the starting material for making higher or complex carbohydrates like disaccharides, starches and cellulose. Human beings can’t digest cellulose.

Monosaccharides

Monosaccharides are the simplest sugars. Two of the most popular ones are Glucose and Fructose. Whereas Glucose contains only sugar, Fructose contains vitamins and minerals alongwith sugar. These are derived mostly from fruits. Thus Fructose are better than glucose.

Disaccharides

Disaccharide means their skeleton is made of two Glucose units. Examples are Sucrose, lactose and maltose.

Starches

Starches are very complex molecules made from large numbers of Glucose units joined together. These are obtained from grains like wheat, barley and maize etc. Due to their complex structure, they are slow to breakdown into human consumable monomers.

How Carbohydrates provide energy?

Carbohydrates are like fuel in a vehicle. Carbohydrates are oxidised by Oxygen we inhale. During oxidation energy is released alongwith water and carbondioxide which are exhaled and again caught by plants and trees for making sugars for themselves and humans and animals.

Why body prefers carbohydrates than fat?

Fat provides about thrice the energy than same amount of carbohydrate. Even then body prefers it especially for giving instant energy to the brain. The reason is the ease with which carbohydrates can be broken down into energy. Also the byproducts are easy to get rid by the body.

Complex carbohydrates like starch take much longer to get hydrolyzed. First of all when we eat them, an enzyme called Amylase which is present in our saliva catalysis the starch breakdown in the belly. Thus the breakdown is slow and not instant and sustained over a longer period of time thus providing lower but sustained amounts of energy.

So in the nutshell the whole foods grains are better and useful to be taken. Carbohydrates from these are not harmful but useful.
