What type of ponge shall we eat?
Our source of carbohydrates is plants. Plants compose carbohydrates in two forms:
A- Storage carbohydrates which are :
1- Easily digested to release glucose quickly.
2- Of compact size for space economy of plant.
3- Of spacial configuration that is compatible with Amylases (starch digesting
Starch represents this group of storage carbohydrates.
B- Structural carbohydrates which are :
1- Of large intra-molecular spaces to hold water inside plant.
2- Not liable to digestion by carbohydrate digesting enzymes to guard against decay of living plants.
3- Of rigid nature for stature of plants ( y have no bones).
Cellulose & Hemicellulose represent structural carbohydrate group.
When humans eat digestible carbohydrates (starchy meals), ir digestion starts as soon as y are admixed with saliva where its amylase splits starch into linear fragments that is ended with formation of soluble glucose which is absorbed through intestine.
When y eat indigestible carbohydrates (fibers), later acquire volume and weight all way till excreted almost undigested and unchanged acquiring consistency of sponge.
When we compare digestive trip of starch and fibers, we find that starch is disappeared from digestive tract easily to appear in blood in form of glucose ,i.e. easily earned large amount of calories, while fibers (cellulose) gets heavier along whole trip and digestive tract works harder to push down water saturated fibers while extracting a small amount of calories present in digestible materials adhered to fibers, i.e. body pays calories to get rid of fibers.
Imagine immersing 2 similar pieces of sugar and sponge in water for a while, sugar will disappear and sponge will be saturated with water needing extra work to be moved off its place. This is what exactly happens upon eating starch and fibers, starch is represented with sugar and fibers represented with sponge in our example.
If you consume a digestible carbohydrate (bread, pasta, rice, desserts..etc) of 400 calories and this carbohydrate requires 150 calories to digest n you gain 250 calories that if not consumed, it would be stored as fats.
But if you consume 100 grams of-sponge- vegetables that have 25 calories and need 80 calories to digest, n you’ll lose 55 grams after excreting it.
Structural carbohydrates (cellulose) form skeleton of any vegetable or fruit and it is digestible carbohydrates amount that determines appreciation of a plant to be of a high negative calorie value.
re are up to 100 plants which contain a plenty of indigestible carbohydrates and minimal digestible carbohydrates. Some of se plants are:
Fibers also form fecal bulk that guard against possibility of serious constipation that results from consumption of diets containing much of white flour and meat.
