Abstract
The quality of fat in infant milk is determined by the fatty acid profile and selected indices describing nutritional value. The aim of this study was to analyze the fatty acid profile and lipid quality indices of infant formulas and compare these data with breast milk. The study material included seven types of cow's milk-based follow-on infant formulas and samples of mature breast milk. The determination of fatty acids was performed using the gas chromatography (GC) technique. Lipid quality indices were calculated based on the relevant equations. Infant formulas contained more medium-chain fatty acids (MCFAs) and oleic acid. Moreover, they contained more than 30% more linoleic acid and more than twice as much α-linolenic acid and docosahexaenoic acid. In contrast, significant amounts of trans fatty acids (TFAs) were noted in breast milk, while infant formulas contained trace amounts. Infant formulas were characterized by a lower AI (Index of Atherogenicity) (0.49-0.98) and TI (Index of Thrombogenicity) (0.48-0.60) and a higher H/H (hypocholesterolemic/hypercholesterolemic) ratio (1.93-2.30) compared with breast milk (1.47, 1.60, and 1.21, respectively). The composition of infant formulas depended on the type of fat added at the production stage and differed significantly from breast milk, particularly in terms of polyunsaturated fatty acids and lipid quality indices.

Identifying Children at Risk of Growth and Nutrient Deficiencies in the Food Allergy Clinic. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2024; 12:579-589. [PMID: 38280452 DOI: 10.1016/j.jaip.2024.01.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 01/16/2024] [Accepted: 01/19/2024] [Indexed: 01/29/2024]
Abstract
BACKGROUND Food allergies affect growth in children by decreasing the availability of nutrients through decreased dietary intake, increased dietary needs, food-medication interactions, and psychosocial burden. Guidelines on food allergy management frequently recommend nutrition counseling and growth monitoring of children with food allergies. OBJECTIVE To provide clear guidance for clinicians to identify children with food allergies who are at nutritional risk and ensure prompt intervention. METHODS We provide a narrative review summarizing information from national and international guidelines, retrospective studies, population studies, review articles, case reports, and case series to identify those with food allergy at greatest nutritional risk, determine the impact of nutritional interventions on growth, and develop guidance for risk reduction in children with food allergies. RESULTS Children with food allergies are at increased risk of nutritional deficiencies and poor growth. Nutritional assessment and intervention can improve outcomes. Identifying poor growth is an important step in the nutrition assessment. Therefore, growth should be assessed at each allergy evaluation. Interventions to ensure adequate dietary intake for growth include appropriately prescribed elimination diets, breast-feeding support and assessment, supplemental formula, vitamin and/or mineral supplementation, appropriate milk substitutes, and timely introduction of nutrient-dense complementary foods. Access to foods of appropriate nutritional value is an ongoing concern. CONCLUSION Nutrition intervention or referral to registered dietitian nutritionists with additional training and/or experience in food allergy may result in improved growth and nutrition outcomes.
