According to figures from a Gallup study in the last decade, almost half of Americans consume cola daily. Another study from 2025 by Business Insider mentions that the average citizen of this country consumes about 355 ml of sugary soft drinks per day, which would mean that for every person who does not drink soft drinks, another consumes approximately twice as much.

This poses a very serious public health problem for the nation, due to the high sugar content of each serving, especially considering that the popular dark cola carries even more risks.

Despite its appealing taste, regular consumption of soft drinks poses serious health risks that are often ignored.

A study published in January in Nature Medicine revealed that in 2020, approximately 2.2 million new cases of type 2 diabetes and 1.2 million new cases of cardiovascular disease worldwide were attributable to sugary drinks.

Composition of a Cola Soda

An analysis reveals that a glass of cola contains an alarming amount of harmful ingredients.

Among them are:

Sugar: approximately 10 tablespoons per serving.

Caffeine: 55 milligrams, which can disrupt sleep patterns and lead to dependence.

High-fructose corn syrup: associated with metabolic diseases such as diabetes.

Phosphoric acid: a compound that can weaken bones and contribute to osteoporosis.

Short-term effects on the body

The effects on the body after consuming a cola can be surprising. In general terms, according to medical literature, we can mention the following:

At 10 minutes: the body absorbs an amount of sugar equivalent to the recommended daily intake.

At 20 minutes: blood sugar levels spike, affecting insulin.

At 40 minutes: caffeine causes pupil dilation.

At 45 minutes: increased dopamine production,generating sensations of pleasure.

After 60 minutes: the digestive system begins to work at an accelerated pace.

Consequences of frequent consumption

Regular consumption of cola can lead the body to depend on high levels of sugar and caffeine. This not only results in a cycle of fatigue and thirst, but also represents a progressive deterioration of health.

It is crucial to consider healthier alternatives that offer real nutritional value.

Relationship of soft drinks with the increase in chronic diseases

Excessive consumption of cola has been linked to an increase in the incidence of chronic diseases in the young population, including obesity, diabetes, cardiovascular diseases, and certain types of cancer. Scientific evidence supports the notion that high consumption of these beverages is a risk factor for the development of multiple pathologies, especially in young people, where the intake of sugary drinks is prevalent. Excessive intake is associated with childhood and adolescent obesity, which in turn increases the risk of type 2 diabetes, hypertension, and cardiovascular diseases. Furthermore, recent studies have shown that regular consumption of sugary soft drinks can accelerate cellular aging and increase mortality from various causes. Frequent consumption of cola causes hormonal imbalances, insulin-glucose dysregulation, and oxidative stress, which can lead to increased adiposity and insulin resistance. These effects increase the likelihood of developing metabolic and neoplastic diseases, as well as exacerbating the onset of respiratory illnesses such as asthma. Likewise, the consumption of artificial sweeteners, present in light or zero versions, has also been linked to associated risks, including mortality from cardiovascular and digestive diseases. In studies conducted on adolescents and young university students, high consumption of cola and other sugary drinks has been linked to a higher prevalence of obesity and lipid disorders. Evidence indicates that reducing the intake of these beverages is crucial to preventing future chronic diseases in the young population. Dark colas, even more harmful. Dark colas are more harmful to the body mainly due to their phosphoric acid, sugar, and caffeine content. The phosphoric acid present in these drinks is associated with kidney damage, promotes the formation of kidney stones, and can cause high levels of phosphorus in the blood, which increases the risk of heart disease, bone weakness, and joint pain. The caffeine in these drinks can also cause insomnia.arrhythmias and negative effects on cardiovascular health.

Finally, the bubbles in these drinks stimulate acid production in the stomach, causing abdominal bloating and affecting the feeling of satiety, which can contribute to weight gain.
