Food sugar (white) is a product that is almost 100% pure sucrose - an organic chemical compound from the group of disaccharides, consisting of glucose and fructose molecules. It is obtained mainly from sugar beets or sugar cane. From a dietary perspective, sugar is a product with high caloric density: 100g of white sugar provides approximately 400 kilocalories (kcal). Sugar is a prime example of the so-called empty calories - it does not contain any vitamins, minerals, protein or fiber. It provides the body only with easily digestible energy, which, if not immediately used by the muscles, is quickly stored as fat tissue.
Our intuitive sugar calorie calculator allows you to quickly convert the calorie content of a teaspoon, spoon or glass of sugar, which makes it easier to consciously limit sugar in your daily diet and drinks.
The impact of excessive sugar consumption on human health
Modern science leaves no doubts - excess sugar in the diet is one of the main causes of the epidemic of lifestyle diseases in the world. The most serious health consequences include:
- Obesity and overweight:Sugar added to food and drinks disrupts the hormonal balance (especially the secretion of leptin - the satiety hormone), which leads to overeating.
- Insulin resistance and type 2 diabetes:Frequent consumption of sugar causes sudden spikes in blood glucose, forcing the pancreas to produce large amounts of insulin. Over time, cells become resistant to the action of this hormone.
- Cardiovascular diseases:Excess sugar increases inflammatory processes in the body, increases the level of triglycerides in the blood and contributes to the development of atherosclerosis.
- Tooth decay:Sugar is an excellent medium for bacteria living in the oral cavity, which produce acids that destroy tooth enamel.
Table of nutritional values and macronutrients in 100g of sugar
The table below shows the nutritional profile of white beet sugar and brown cane sugar per 100 grams:
| Nutrient | White sugar (in 100g) | Brown sugar (in 100g) | Difference / Dietary conclusions |
|---|---|---|---|
| Energy value | 400 kcal | 380-390 kcal | The difference in caloric value is negligible and has no significance for health. |
| Simple carbohydrates | 99.9 g | 97.0 g | Both products are almost exclusively pure sucrose. |
| Dietary fiber | 0.0 g | 0.0 g | No fiber, quick absorption. |
| Protein | 0.0 g | 0.0 g | No building blocks. |
| Fat | 0.0 g | 0.0 g | No fat. |
| Minerals (e.g. iron, calcium) | None (0 mg) | Trace amounts (from molasses) | The amounts of minerals in brown sugar are too small to have any effect on health. |
| Glycemic Index (GI) | 70 | 65 | Both products have a high glycemic index. |
Frequently asked questions (FAQ)
How many calories does one teaspoon of sugar have?
One standard level teaspoon of sugar weighs approximately 5 grams. It provides exactly 20 kilocalories (kcal).
Is cane (brown) sugar healthier than white sugar?
No, this is a common marketing myth. Brown sugar differs from white sugar mainly in that it has not been completely purified from molasses (hence its color and aroma). Chemically, it is still the same sucrose, with almost the same caloric value and effect on the body.
What is the maximum recommended amount of sugar per day?
According to the guidelines of the World Health Organization (WHO), free sugars (added to dishes and naturally present in juices and honey) should constitute less than 10% (and optimally less than 5%) of the daily energy requirement. For an adult with a 2,000 kcal diet, this gives a maximum of 25-50 grams of sugar per day (approx. 5-10 teaspoons).
Is coconut sugar a good alternative to white sugar?
Coconut sugar has a slightly lower glycemic index (GI approx. 35-40) than white sugar due to the inulin (fiber) content, but in terms of caloric value and fructose content it is very similar. It is not a dietary product and should be consumed in small quantities.
What is the best way to replace sugar in the kitchen on a reducing diet?
The best calorie-free or low-calorie substitutes are natural and synthetic sweeteners, such as erythritol (0 kcal), xylitol (approx. 240 kcal/100g, half as much as sugar and beneficial for teeth) and stevia. They do not raise blood glucose levels.
