It is preferable to consume a homemade chocolate bar rather than an ultra-processed industrial version, while remaining mindful of the total caloric density.

This advice is based on the distinction between whole foods and ultra-processed foods (UPF). Research, particularly observational studies (such as those published in the BMJ), suggests a correlation between high UPF consumption and various health risks, often linked to nutritional density, additives, and technological processing. By preparing one's own snack, one controls ingredient quality (fewer preservatives, potentially better-controlled glycemic index), which is a solid point validated by nutritionists. However, the statement remains cautious: energy density remains high. It is important to note that the body metabolizes calories in a similar manner, whether they come from a homemade or industrial source; the benefit therefore lies more in the quality of the nutrients provided than in an absence of caloric consequences.
