Of course, YES.

The brain uses more energy than any other organ in the human body and glucose is its source of fuel. But what happens when the brain is exposed to the excessive amount of sugars in the standard American diet? In this case, more is definitely not better.

In the brain, excess sugar impairs both our cognitive skills and our self-control (having a little sugar stimulates a craving for more). Sugar has drug-like effects in the reward center of the brain. Scientists have proposed that sweet foods—along with salty and fatty foods—can produce addiction-like effects in the human brain, driving loss of self-control, overeating, and subsequent weight gain.

In early humans, this stimulus helped lead them to calorie-rich foods, which aided survival when food was scare. But now this primitive drive contributes to our epidemics of obesity and diabetes. The behavioral and neuro-biochemical characteristics of substance abuse and overeating are quite similar, and the idea of food addiction is gaining ground among scientists.

YES!

Have you ever felt dizzy or sleepy after eating too much? I am sure, you must have. That happens because the food that we eat completely gets converted to sugar. Our body needs energy to function and this energy is gained through food. The body then breaks down the nutrients from the food in the digestive system to turn it into glucose that will then convert it into energy.

Post-eating, the body releases hormones such as amylin, glucagon and cholecystokinin. These hormones increase blood sugar levels, creating a feeling of fullness and producing insulin that will be streamed through cell tissues and provide energy for them. At the same time, the brain releases serotonin that causes drowsiness.

Moreover, food also influences melatonin production in the brain. This is the hormone that is responsible for sleepiness post-meal. Melatonin is created by converting the amino acid tryptophan into serotonin, which then turns into melatonin.

The brain is the organ that needs sugar more than others because it is known that food turns into a cloc to nourish the brain, but everything is more than it is harmful to the body through diabetes, as well as feeling dizzy and obesity.

Not all Sugars are good for the brain the most important one is glucose which is a small molecular that can easily diffuses through the blood brain barrier and utilizes by the brain to generates the required Energy needed to perform its varIous normal and important activities. Also glucose in the brain would be converted to fatty acids that are important as structural components of the brain and nervous systems. These fatty acids are large molecules and can not get through the brain due the presence of the blood brain barrier

So glucose is indispensable for the brain activity and should be maintained at normal concentrations all the time

Since 2004, I have diabetes type II. I decided not to take medicine. Because I am on low carbohydrates diet (not only sweet food but also bread, rice, potatoes,...), I focus more on my work and concentrated better details and also I can work longer hours. My understanding is that sugar could be good for brain but bad for the immunity system. I was reading somewhere that sugar accelerates aging of cells.

Dear Dr. Zin Eddine, I wish you healing and lasting health and prolong your life.

I think, yes
