MARTINEZ ALVAREZ, Jesús Román. The energy density and the nutritional quality of diet depending on their sugar content. Nutr. Hosp. [online]. 2013, vol.28, suppl.4, pp.57-63. ISSN 1699-5198.

Sugar content in foods cannot be distinguished from added sugar, although it is true that this added sugar brings mainly energy and no other essential nutrients. On the other hand, in the context of diet, sugar helps make it more varied and palatable allowing including foods that may otherwise not be would consume, thus indirectly contributing to the intake of other nutrients. Having interest in knowing the possible relationship between a high intake of sugars and the decrease in micronutrients intake, we noted that the nutrient density of the diet might be influenced by factors such as the high presence of sugar added to food. It seems that this nutritional dilution produced by adding sugar to food is, in general, not very significant and, often, offset by the fortification in micronutrients that we usually can find in many sugary products. After a detailed analysis of the published studies on the subject, it has been found that there is no a clear evidence of the hypothetical micronutrient dilution that would occur by adding sugar to the diet. On the other hand, given that the addition of sugar to the diet doesn't seem to report any remarkable advantages from the point of view of the intake of micronutrients; It seems reasonable to promote a moderate consumption of foods and sugary drinks, so in that way, they become an important extra energy source. It should also be borne in mind that the addition of sugar to the diet does not seem remarkable report any advantage in terms of intake of micronutrients. For this reason, it seems logical that the consumption of sugary food and sweet drinks will be moderate given the ease of consumption and the likelihood of their becoming a major source of energy. Finally, it is concluded on the need for further research on the mechanisms underlying that, up to now showed no, possible displacement of micronutrients and other food components of the diet that could occur in cases of consumption of foods with a high sugar content, as well as their impact from a clinical point of view.
