Zinc bioaccessibility of foodstuffs after <i>in vitro</i> study in children with illnesses.

ABSTRACT:

Background

Childhood is a life stage particularly sensitive to malnutrition, including obesity, celiac disease, and food allergies. Zn is an essential element in development, metabolism, and the regulation of inflammatory processes and oxidative stress.

Objective

Zn bioaccessibility (Zn-BA), an indicator of the fraction of Zn available for intestinal absorption, is commonly evaluated through in vitro digestion models. This study applied a novel in vitro digestion-fermentation method to assess Zn-BA in various raw and cooked foods using fecal inocula from children with gluten-related disorders (GRD-CH), obesity (OB-CH), and allergy/intolerance to cow's milk protein (AICM-CH).

Results

The results showed that Zn bioaccessibility in the large intestine (Zn-B
