Food Calorie Table: How to Read the Numbers

You open a package or a food app and see a calorie number. The number is there, but what it means in practice is often unclear. Let's sort out where the numbers in calorie tables come from and how to understand them calmly.

What calorie content is and what it is measured in

A calorie is a unit of energy. The energy value of a food is the amount of energy the body gets from it. Food gives the body energy to function: to breathe, walk, think, and stay warm. On packaging, energy is given in kilocalories (kcal) or kilojoules (kJ).

A guide for adults: about 2,500 kcal per day for the average man and about 2,000 kcal for the average woman. The exact number depends on age, weight, height, and activity. If you eat and drink more energy than you use, weight goes up: the body stores the excess as fat. If you take in less, weight goes down because the body draws energy from its stores.

How a food calorie table is organized

In a calorie table, you look at the energy number. What to pay attention to:

• the energy on the packaging is listed under the heading "energy";
• calorie content shows the amount of energy, not the overall healthfulness of the food;
• calorie information is sometimes available in restaurant menus.

Which foods have the most calories

Foods and drinks with a lot of calories, sugar, and fat are often easier to find. Outside the home, such food is easier to come across: vending machines, canteens, and holiday tables do not always offer healthy options with fewer calories. Less healthy food may cost less than healthier food.

The cooking method also matters: baking and grilling are considered healthier methods than frying.

Which foods have few calories

There is no single list of low-calorie foods; nutritious foods include fruits, vegetables, starchy foods, protein, and unsaturated fats. Such food provides vitamins, minerals, and fiber.

Calorie content, however, remains only a measure of energy. A low number by itself does not indicate that a food is healthy and does not replace an assessment of the diet as a whole. There is no single list of sweets by calorie content; they can be compared by the number under the heading "energy" on the packaging.

What calorie content does not show about a food's healthfulness

Calorie content answers one question: how much energy. It says nothing about vitamins, minerals, fiber, or how much salt and added sugar the food contains. Two foods with the same number can be completely different in composition — you cannot choose the "better" one by a single number.

Weight and health depend on more than arithmetic. They are influenced by home, work, and surroundings, family habits and genes, sleep, emotions, certain medications, and chronic conditions. Adults are advised to get at least 150 minutes of physical activity per week. When it comes to weight, a doctor assesses the situation: they look at body mass index and overall health and advise what weight is healthy specifically for you.

A calorie table and calorie counting are not in themselves a reason to call an ambulance; 103/112 — for signs that threaten life, for example suspected stroke or heart attack.
