Abstract

Cambodjas rige ferskvandsressourcer er beskrevet som blandt de mest produktive i verden. Sammen med ris udgør fisk og andre akvatiske dyr (OAA) en vigtig del af Cambodjas traditionelle kost. Fiskene i den Cambodjanske kost dækker flere hundrede ferskvandsarter fra Mekong-flodsystemet. Nogle arter spises hele, med ben og hoved. Fisk er en fremragende kilde til animalsk protein af høj kvalitet, mikronæringsstoffer og essentielle fedtsyrer, såsom n-3
langkædede flerumættede fedtsyrer (LC PUFA). Fisk og deres bidrag til LC PUFA har mange sundhedsmæssige fordele, herunder stimulering af børn kognitive udvikling.

På trods af de rige og produktive akvatiske føderessourcer rangerer Cambodja blandt de mest fødevareusikre lande i verden med en høj forekomst af underernæring. Spædbørns overgangskost i Cambodja mangler variation og indtaget af fisk er ernæringsmæssigt utilstrækkeligt. WinFood-projektet i Cambodja havde til formål at udvikle ernæringsrigtige produkter til spædbørn baseret på traditionelle fødevarer (primært ris og fisk), egnet til distribuering som forarbejdede pakkede produkter (PCFP). Fiskebaseret PCFP har potentiale
til at bidrage til at forbedre overgangskosten i Cambodia ved at give adgang til et nærende, praktisk og stadig kulturelt traditionelt produkt.

Hovedformålet med denne afhandling er at undersøge potentialet for at produkter baseret på lokale ferskvandsfisk kan bidrage til bedre ernæring blandt børn i Cambodja, ud fra perspektiver på behov, indvirkningen på n-3 LC PUFA status, og omsorgspersoners præferencer og prioritering til at betale for sådanne produkter.

The mothers demonstrated advanced knowledge of aquatic foods recognizing on average 113 fish species and 14 OAA species available in their surrounding aquatic environment, and consuming 69 different species the previous rainy season. The diversity in children{\textquoteright}s diets were much less diverse. The RCT study found no differences in blood n-3 long-chained polyunsaturated fatty acids (LC PUFA) between the fish-based and the non-fish-based groups. A stratified sample of children no longer breastfed at 15 months of age indicated that the effect of the intervention foods was modified by positive impact of breastfeeding on LC PUFA. The WTP analysis showed that rural participants were willing to pay more than participants in rural settings for fish-based PCFP. Various brands of global and local PCFP products were available on the market. Caretakers were familiar with those brands but only few had ever consumed them. Most participants considered homemade porridge healthier, more practical, and preferred by children. In conclusion, fish-based PCF is potentially a feasible nutrition intervention because it can improve fish consumption in children, and potentially improve fatty acid status, especially in non-breastfed children.",
