Choosing between the multitude of similar products offered by a supermarket has become almost an escape room. The options for basic foods such as bread or milk have multiplied, the range is increasingly wide, and deciding can sometimes be complicated. A good way to tip the scales one way or the other is to look at the labels of different products, compare them, and choose the one that best fits each person's nutritional needs. However, interpreting them is not always easy, as processed foods include a long list of ingredients, some of which are additives associated with a number or a technical name, and it is complicated to separate the wheat from the chaff. ARA has consulted various experts in nutrition and endocrinology to create an easy guide that allows understanding food labels and leaving the supermarket with the conviction of having chosen the best option.
