Description
Summary:[Display omitted] •Mango juice by-product (JBP) modulated proteins of the immune system in children.•Mango JBP reduced gastrointestinal and respiratory infection symptoms in children.•Mango JBP is rich in extractable and non-extractable polyphenols. The study aimed to evaluate the effect of a mango juice by-product (JBP) on upper-respiratory and gastrointestinal tract infection symptoms in children (6–8 y) in a randomized, double-blind, parallel, case-control study. For two months, children drank either flavored water (control group) or a mango JBP-based beverage (0.04 g·ml−1; treatment group); such beverage provided 1.1 g, 278.6 mg and 7.8 mg of dietary fiber, extractable polyphenols (mono-to-hepta galloyl hexosides, mangiferin), and hydrolysable polyphenols (ellagic/gallic acid) per portion, respectively. Mango JBP reduced the incidence of gastrointestinal (flatulencies and abdominal inflammation; p ≤ 0.007) and upper-tract respiratory (crystalline mucus, itchy throat, runny nose, itchy nose, and sneezing; p ≤ 0.038) and such benefits were associated to increased serum levels of PAI-I, MIP-1a, and MIP-1b (p ≤ 0.04) and decreased levels of IgG, MIF, and osteopontin (p ≤ 0.01). We concluded that JBP-based beverage has immunomodulatory properties, useful to prevent or even treat common infectious diseases in school-age children.
