Now we will discuss about the effects of sugar on our health.
Food contains carbohydrates that are metamorphosed into glucose during digestion. As opposed to carbohydrates, Glucose is easily assimilated by the body. Glucose is the main fuel of our body. It allows the proper functioning of the organs like the brain, muscles and the pancreas for example.
In our brain:
The brain is almost exclusively glucose dependent. Our neurons continually need it, just like oxygen. While the brain represents only 2% of our weight, it uses 60% of our body's glucose. It is estimated that an adult brain consumes about 140 g of glucose a day.
Several experiments have shown that a diet rich in carbohydrates favouring the acquisition of knowledge and memorization.
In pancreas:
The pancreas has an exocrine function which consists in the development of pancreatic juice which plays a role in digestion.
It also has an Endocrine function which is involved, among others, in the manufacture of insulin whose role is to maintain constant glycemia. This function requires the synthesis of two hormones: insulin and glucagon
• During a rise in blood glucose, the pancreas releases insulin which promotes the entry of blood glucose into the storage organs. The blood sugar will then decrease and become normal again.
• glucagon has the opposite effects of insulin: it releases glucose into the blood by glycogen degradation. In case of need of sugar in our cells, when the glycemia is low, (intense exercise, fasting), glucagon, transforms the glycogen into glucose and releases it into the blood vessels. For example, glucose can be stored as glycogen in liver or muscles
Even if sugar can be very beneficial to the body, it can also be harmful:
For example, poor dental hygiene combined with sugar consumption leads to cavities. Indeed, sugar feed the mouths bacteria and help them to produce acids that demineralize enamel and create caries.
Moreover, some diseases are due to problems with blood glucose regulation. For example, diabetes is due to poor regulation of blood glucose, because of insulin that is defective or nonoperative.
The excess of sugars is not good for people suffering from these disorders. However, sugar is also harmful for people in good health. It can cause obesity, digestive disorders, drop in energy and long-term cardiovascular problems.
To end, sugar can be considered as a drogue, indeed there is a real dependence on it if we are eating too much sugar. You are eating sugar; your brain makes dopamine which is responsible of dependence and pancreas made insulin which help to decrease you’re glycemia. After that, your glycemia is too low and your body ask for food and mostly sugar. And the cycle repeats again and again.
