Association of Serum Polyunsaturated Fatty Acids (PUFAs) and Children's Dietary Inflammatory Index (C-DII) with Recurrent Respiratory Infections in Children: A Cross-Sectional Study.

To assess the associations between serum and dietary polyunsaturated fatty acids (PUFAs), as well as the inflammatory potential of diet measured by the Children's Dietary Inflammatory Index (C-DII), and recurrent respiratory infections (RRIs) in children. We enrolled 44 children aged 3-16 years with RRIs and 44 healthy controls. Dietary intake was assessed using a 7-day food record from which PUFA intake and C-DII were calculated.

Iron status and dietary iron intake of vegetarian children from Poland.

Background/aim: In Poland, vegetarian diets are becoming more and more popular. The aim of this study was to examine the effect of iron intake on iron status in vegetarian children.

Methods: Dietary iron intake, iron food sources, blood count, serum iron, ferritin level and total iron-binding capacity were estimated in two groups of children, namely vegetarians (n = 22) and omnivores (n = 18) of both sexes, aged from 2 to 18 years.

Impact of vegetarian diet on serum immunoglobulin levels in children.

Background: Nutrition plays an important role in immune response. We evaluated the effect of nutrient intake on serum immunoglobulin levels in vegetarian and omnivore children.

Methods: Serum immunoglobulin levels and iron status were estimated in 22 vegetarian and 18 omnivore children.
