Can we live without sugar in our body? – Latest News, Breaking News, Top News Headlines


A healthy diet is associated with low sugar consumption, but that does not mean that we should give it up completely

Consuming a lot of sugar can cause health problems, from tooth decay to obesity and diabetes. This is why it sounds reasonable that we lower the amount of sugar we eat, but what happens if we cut it completely?

Low in carbohydrates

In general we think of sugar, as that crystalline substance that we add to some sweet foods or to our coffee, but that is just sucrose, one of the many sugars that exist.

Sugars they are part of a type of nutrients: carbohydrates. These along with proteins and lipidsThey are vital for our body to function properly.

Carbohydrates can be classified into sugars, starches and fiberto. The latter is not actually a nutrient, because it is a type of carbohydrate that we cannot digest, but which is very important for the processes of digestion.

Among the many current nutrition trends are low-carbohydrate diets, in which the consumption of foods such as potatoes and bread, which contain starches and everything that contains sugars, such as rdrinks and desserts.

Does not contain sugar

Sugars are important to the body because they provide energy: cellular respiration is the metabolic process in which these compounds are converted into adenosine triphosphate, ATP, the molecule that our cells can use as an energy resource.

Much of the functioning of our body depends on the intake of sugars: nothing more brain consumes 20% of the energy produced, from glucose metabolism.

So if we completely cut out sugars it could be that our body does not work completely well. But it turns out that the body has a « rescue » mechanism for those situations.

On the one hand, the lipid metabolism it can provide energy and, on the other hand, it can also produce glucose from compounds such as amino acids, which we obtain from proteins, in the process called gluconeogenesis.

No calories

Low-carb diets build on these mechanisms in which the body takes advantage of other nutrients that it has on hand instead of carbohydrates, and for that reason, if they are followed properly and with medical supervision, they can give benefits.

But it is practically impossible, and not entirely healthy, for us to stop eating sugars completely.

If we eat fruits and vegetables we are ingesting carbohydrates: in some more than in others, which we can notice in its taste, for example a banana has more sugar than a cucumber, but in the end all fruits and vegetables contain a certain amount of carbohydrates.

If we don’t want to overindulge in our sugar intake, the answer is not to stop fruits, but rather to limit our consumption of processed foods to which sugar is added, or have sodas or sweet drinks.

Why it is not possible to survive without consuming « calories », but it is important that most of them come from foods that provide us with other nutrients and not just energy. Think about that when you make your grocery list.
