Understanding nutrition labels

Reading and understanding nutrition labels

Figuring out exactly what the nutrition labels mean can be tedious. You might be wondering what you should be focusing on and what is the meaning for each line item.

We have reproduced an actual nutrition label below and will explain how to read it.

1. Serving size

   Information regarding servings per pack and recommended serving size will be shown on each nutrition label.

   In this example, the product is a canned drink and the whole can is meant as one serving size of 240ml.

   Many other products – for example, canned soup or a tin of sardines – list the serving size as 4 servings. This will be clearly shown under the serving size area of the label.

   Serving size is probably the first important item to note as the rest of the information is dependent on the serving size.

2. Average composition

   This area on the label tells you what the product comprises in terms of energy, fat, protein, carbohydrates, sugar, and salt.

   Some labels also contain additional information like vitamins and mineral content. However, it must be pointed out that the Malaysian food regulations state that vitamin and mineral content can only be declared if there is a significant content of vitamins and minerals in the product. This is to protect consumers from misleading information.

   1. Energy
      • Calories are an important factor in the nutrition content of food. This can be found listed under Energy.
      • Let’s talk about the kcal unit of measurement. Where food is concerned, 1 kcal actually equals 1 Calorie. The confusion is due to the scientific definition of calories, which is the amount of heat required to raise one kilogram of water by 1 degree Celsius. Just remember that 1 kcal = 1 Calorie.
      • Energy is also sometimes listed as kJ (kilojoules). This is just another unit of measurement that some people are more familiar with.
   2. Fat
      • Fat content is shown in grams, and this shows how much fat the product contains. Some labels break down the type of fat into saturated fat and trans-fat.
      • While your body needs fat, too much fat in a product is not good and alarm bells should ring if there is a high trans-fat content on the label. That's what you should look out for.
   3. Other nutrients
      • The rest of the information shows the amounts of protein, carbohydrates, sugar, and sodium (salt). Once again, look out for products with high sugar and/or sodium content. Too much of either of these is usually not a good sign.
   4. Product composition value
      • There are two columns that reflect the value of the product composition:
        • One column shows the composition for one serving size.
        • The other column shows the composition for 100ml or 100g of the product.
      • This is particularly useful when you compare the composition values of two different products that may not have the same serving size.
      • By standardising it to 100ml (liquid) or 100g (solid), the consumer is able to make a fair comparison without being influenced or confused by serving size.
