A
Food labels appear on almost every product sold in supermarkets today. These labels give important information about what is inside the package. They show how much energy the food contains, along with details about sugar, fat, salt, and other parts of the food. Most countries now require companies to print this information clearly on their products. The main goal is to help people make better choices about what they eat.

The energy in food is measured in units called calories. A calorie is the amount of energy needed to raise the temperature of water by one degree. When people eat food, their bodies use this energy to work, move, and stay alive. Different foods contain different amounts of calories. For example, one apple has about 95 calories, while a chocolate bar can have 250 calories or more. Labels show this number so people know how much energy they will get from eating the food.
C
Labels also list the main types of food substances. Carbohydrates are one important type, and they give the body quick energy. Bread, rice, and pasta contain high amounts of carbohydrates. Proteins help build and repair muscles and other body parts. Meat, fish, eggs, and beans are good sources of protein. Fats provide energy too, but they contain more calories than carbohydrates or proteins. Butter, oil, and cheese have high fat levels.
D
Sugar information appears separately on many labels because eating too much sugar can cause health problems. Sugar makes food taste sweet, but it can lead to weight gain and tooth damage. Some foods contain natural sugars, like the sugar in fruit. Other foods have added sugar that companies put in during production. Labels in some countries now show both types separately. This helps people see how much extra sugar has been added to products like soft drinks and breakfast cereals.
E
Salt is another substance that labels show clearly. The body needs a small amount of salt to work properly, but too much salt can be dangerous. It can raise blood pressure and increase the risk of heart disease. Many processed foods contain high levels of salt to make them taste better and last longer. Ready meals, canned soups, and snack foods often have more salt than people expect. By reading labels, people can compare products and choose ones with less salt.
F
The serving size section tells people how much food the label information describes. This is important because packages often contain more than one serving. For instance, a bottle of juice might show 100 calories per serving, but the bottle contains two servings. This means drinking the whole bottle gives 200 calories, not 100. Many people miss this detail and eat or drink more than they realize. Understanding serving sizes helps people control how much they consume.
G
Some labels now use simple symbols or colors to make information easier to understand. Traffic light labels use red, yellow, and green colors. Red means the food is high in something like sugar or salt. Yellow means medium amounts. Green means low amounts. People can see these colors quickly without reading all the numbers. This system works well in busy shops where people make fast decisions. Studies show that colored labels help people choose healthier options more often than labels with only numbers.
