On the other hand, our results of mean TWI per kg of body weight were close to those reported onwater turnover by Fusch et al. in 1993 in the same age groups(3). Three-quarters of the infants and most toddlers had a TWI/energy ratio below the AI set for their age(5), but overall our results were higher than those reported in Mexico(23). This in line with the high energy densities of the diets we reported previously as increasing with age and the introduction of solid foods, on average from 64 to 85 kcal/100g and even over 100 kcal/g in more than 10% of children older than 18 months (44). The gradual increase of non-adherence to the AI after six months of age was linked to the increasingly significant share of solid food with age. The decreasing consumption of formula or milk was not compensated for by the drinking of water. The reported median age for the introduction of solid food in the study sample was 4.9 (3.9–5.9) months(44).
