Sugar is an absolutely safe product if you use it correctly and in moderation. If we recall the school curriculum, the sucrose molecule consists of two monosaccharides of glucose and fructose. Once in the body, sugar is finally broken down in the human body to these simple carbohydrates. Both glucose and fructose are included in a number of natural foods that people have been eating for many centuries. These are honey, fruits, berries, vegetables, cereals. Glucose is the main physiological source of energy for the full functioning of the whole body: the brain, muscles, lungs and other vital organs. Glucose provides relaxation and sedation, as it is able to increase the level of the hormone of joy, serotonin. That is why after a piece of chocolate, a glass of soda or sweet fruit, we feel a surge of strength and mood improvement.
The taste of sugar is clear and pleasant to a person from infancy. The famous molecular biologist John Medina , who is the author of a number of popular scientific works on the physiology of the brain, writes that a person develops a love for sweets in his prenatal state. At about 7 months of gestation, the child shows a change in swallowing behavior when her mother eats sugary foods . And then, when the baby already has a connection of taste buds with the corresponding parts of the brain, they perceive the sweet taste as pleasant.
At the stage of breastfeeding, the sweet taste of breast milk containing milk sugar - lactose, fixes the human body’s attitude to sweet taste, as desirable, pleasant, calming and reducing anxiety.
Sweet taste makes you saturated with carbohydrates in order to maintain the necessary level of energy and strength. On average, the human body consists of proteins (19.6%), fats (14.7%), carbohydrates (1%), minerals (4.9%) and water (58.8%). He constantly spends his reserves on replenishing the expended energy, which is necessary for the normal functioning of internal organs, maintaining physical and mental activity .
More than 50% of this energy we get from carbohydrates. The need for carbohydrates in adults is 4-6 g per 1 kg of body weight, and with heavy physical work or active sports - 8 g per 1 kg. Of these, 80-90% (300-400g per day) should be complex starchy carbohydrates (vegetables, fruits and cereals), and the consumption of fast carbohydrates, mainly sugar contained in (juices, sweet soda, grapes, sweets, bananas , dried fruits, chocolate, honey) should not exceed 10-20% of the daily caloric intake (about 50-100g per day). Fast carbohydrates are easily absorbed by the body and quickly replenish energy costs, especially with active physical exertion. Since this energy is necessary for the normal functioning of the body, regular consumption of a reasonable amount of sugar is not contraindicated in healthy people. The risk is only its excessive amount. The share of easily digestible carbohydrates (glucose, sucrose, lactose, etc.) in healthy people should not exceed 25% of the total amount of carbohydrates in the diet. Excessive intake of simple carbohydrates provokes an increase in blood sugar and, as a result, negatively affects the functioning of the pancreas. To a healthy person who does not have problems with carbohydrate metabolism or being overweight, there will be no harm from moderate consumption of sugar-containing foods or drinks.
Thus, there is no need to exclude sugar from your diet, which means you can without be wary of treating yourself to a chocolate bar or a glass of sweet soda like cola, thereby gaining a boost of energy and good mood throughout the day.
Remember that it’s important to just follow the sugar intake and, most importantly, maintain a healthy lifestyle and constant care tsya on svotm diet, making it the most balanced and complete.
