When we see a bottle labeled “flavored water,” the immediate feeling is that it is something light, refreshing, almost like water… maybe with a slight hint of taste. In practice, in most cases it is a sweetened drink, and sometimes also high in sugar, closer to light juice than to water. In a 500 ml bottle of flavored water from a well-known company, for example, there are:
– 18 grams of carbohydrates – which is actually almost 4.5 teaspoons of sugar.
– 75 calories – meaning the equivalent of a small glass of juice, like eating an apple, or like eating 2 slices of light bread, and all of this in a product labeled only as “water.” With the listener in the program I spoke with him about sweeteners and their impact on our health.
List of ingredients in the bottle:
Reading the ingredients reveals:
Mineral water (about 94%): Meaning 6% is already not just water.Liquid fructose: A type of simple sugar, the kind that causes abdominal fat!Citric acid: An acid that adds a sour taste.Flavor and aroma extracts: Meaning artificial or concentrated flavoring substances.B vitamins: A marketing addition that is not always necessary.
Fructose and abdominal fat – the research link: I want to expand on the second ingredient in the water list… which is fructose. Fructose is a type of simple sugar found naturally in fruits, but also in very high amounts in sucrose (regular white sugar) and high-fructose corn syrup – which are added to a huge variety of processed foods.
Unlike glucose, which is absorbed by cells and used to produce energy, fructose is broken down mainly in the liver – where it undergoes a process that leads to fat production. Studies show that a diet rich in fructose contributes to an increase in visceral abdominal fat – the fat that surrounds internal organs and is considered especially dangerous. A study published in the “Journal of Clinical Investigation” showed that high fructose consumption over 10 weeks led to a significant increase in abdominal fat, even when total caloric intake was not excessive.
The reason: Fructose promotes fat production in the liver (de novo lipogenesis), makes appetite regulation more difficult, and is also linked to increased insulin levels and inflammation. This is also one of the reasons why added sugar – and not just calories – is linked to abdominal obesity, diabetes, and metabolic syndrome.
In simple words, liquid fructose is a simple sugar that causes abdominal fat, increases the craving for sweets, contributes empty calories – and anyone who drinks it throughout the day inside “flavored water” is definitely not drinking “just water.”

Weight gain: When calories are consumed in liquid form, the body almost does not “count” them like solid food. In other words, drinking flavored water that contains sugar does not reduce appetite in proportion to the number of calories that entered the body. The result is a situation where extra calories are consumed without reducing food intake later on.
Nutrition studies show that sweetened beverages are associated with increased daily calorie intake precisely because of this mechanism, and therefore they are considered one of the silent contributors to weight gain.
Impaired sensitivity to the natural taste of water: Regular consumption of drinks with sweet or sour flavors changes the sensitivity threshold of taste buds. Over time, plain water is perceived as “bland” or insufficient, which leads to continued dependence on sweetened drinks. This is a known adaptation mechanism that makes it harder to return to natural drinking habits, especially in children but also in adults.
The “health compensation” feeling that leads to overeating: When people choose flavored water from the perception that they are making a healthy, calorie-free choice, a feeling of “I earned it” is sometimes created, which leads to unconscious compensation in eating. This is a known effect in nutrition psychology, where a choice perceived as healthy later allows us to “permit ourselves” more, thereby harming overall calorie balance.
Unnecessary additives: Adding B vitamins to water sounds positive, but for most people who eat a balanced diet there is no real need for this. These vitamins are excreted in excess through urine, and therefore do not actually contribute to health when not required. In some cases, excessive intake of supplements over time is also not desirable.
Effect on teeth – far beyond sugar itself: After concluding that this is actually juice… when it comes to sweetened beverages, the damage to teeth does not come only from the amount of sugar, but also from the way the drink is consumed and its acidity.
The sugar in the drink serves as food for bacteria in the oral cavity, which break it down and produce acids. These acids lower the pH in the mouth and damage tooth enamel, which is the outer protective layer of the tooth.
When drinking sweetened beverages throughout the day in small sips, a situation is created of continuous acid exposure, without recovery time in which saliva can neutralize acidity and repair damage. In other words, not only quantity matters, but also frequency – “light” drinking throughout the day damages teeth more than concentrated drinking in a short time.
What to drink? Plain water! The official recommendations of health organizations, such as EFSA (European Food Safety Authority), are to drink an average of 2 liters of water per day for women and 2.5 liters for men, including water coming from food.
But in practice, individual need varies greatly – depending on weather, activity level, type of diet, and overall health. How do you know if you are drinking enough? The simplest and most reliable sign: Urine color. Very light urine (like lemonade) indicates good hydration, while dark urine suggests lack of fluids. Fatigue, headache, or unexplained hunger can also be a sign of needing water.
The most important tip is actually not to wait for thirst. Thirst is already a late sign. It is better to drink throughout the day – slowly, gradually, and train the body to receive water naturally.
Bottom line: Flavored water is not a small treat, but another marketing juice with a misleading name. Don’t be confused by words like “refreshing,” “natural,” or “water” – look at what is inside.
