Impact of Perinatal Exposure to Non-caloric Sweeteners on Food Preferences and Weight Gain in the First Year of Life
31 mai 2019 mis à jour par: Martin Gotteland, University of Chile
Determination of Perinatal Exposure to Non-caloric Sweeteners. Implications for the Development of Preferences for Sweet Taste, and Weight Gain During the First Year of Life
During last years, non-caloric sweeteners (NCSs) have been increasingly incorporated into foodstuffs in replacement of sucrose in Chile.
This situation has reached a point where it is currently difficult to find sugary foods without NCSs.
As a result, the voluntary and involuntary consumption of these additives is growing significantly in the population, increasing the risk of exceeding the acceptable daily intake (ADI), especially for children.
This situation is worrying as recent evidence suggests that NCSs are not inert in the body and can trigger adverse metabolic effects.
For example, the consumption of beverages with NCSs has been shown to favor the development of obesity and type-2 diabetes in children and adults, and a recent study reported that the intake of NCSs during pregnancy was associated with a greater weight gain of the child at one year.
It is likely that certain NCSs pass into the amniotic fluid and that the fetus is exposed to some of these compounds during pregnancy.
This situation would persist in the infant through breast milk, as some studies detected sucralose and acesulfame-K in this fluid, even in mothers who claimed not to consume them.
However, the real impact of NCS exposure during the neonatal period on the child health has been few studied.
Therefore, the aim of this study is to determine the concentration of NCSs in samples of amniotic liquid and breastmilk and to correlate these data with the NCS intake by the mothers.
Mothers/children will be classified in quintiles according to the results obtained.
In the children from quintiles 1 and 5, we will also study whether neonatal exposure to NCSs may affect the sweet taste threshold and the preferences for this taste, the levels of salivary insulin and the weight gain in the first year.
Breastmilk microbiota and child fecal microbiota will be also evaluated.
