The women in the project were asked to consume the recommended amount (2 portions per week) of an oily fish, salmon. However, the fish to be consumed by the women has been farmed by techniques developed in AquaMax that produce fish that are highly nutritious with high levels of the desired long chain omega 3 fatty acids and, of equal importance, are essentially contaminant free.
The fish has been tested by scientists at the National Institute of Nutrition and Seafood Research (Norway) and found to be of an exceptional standard in both terms of safety and nutritional content. Using this salmon the research teams have evaluated health benefits of oily fish consumption on health, nutritional status and allergic disease in pregnant women and their infants. Thus, the risk to babies in the AquaMax study from possible contaminants in the fish consumed by their mothers has been essentially eliminated.
The AquaMax Salmon used for the SIPS - Salmon in Pregnancy Study
The salmon used for SiPS was farmed specifically so as to provide fish that were rich in Ω-3 PUFAs and low in contaminants. This aquaculture, part of AQUAMAX, was made by the Skretting Aquaculture Research Centre (Stavanger, Norway) under the supervision of Grethe Rosenlund, producing more than 2 tons of salmon. The fish were filleted into 150 g portions and frozen individually in vacuum-sealed bags in Norway, from where they were shipped to Southampton and stored at -30˚C until delivery for the trial. Enough salmon was provided for the women and other family members if desired. The salmon was provided on a monthly basis and the fillets were stored in the home freezer of the participants until the day of cooking. Detailed nutrient and contaminant content of sample fillets was measured at the National Institute for Seafood and Nutrition Research, Bergen, Norway.
Each portion of salmon contained 1.16 g DHA, 14 micro-g vitamin D3, and 43 micro-g selenium. Not only was the salmon rich in protein and nutrients but it also was exceptionally low in contaminants.
Two portions per week would supply an extra 115% of Ω-3 PUFAs, 10% of selenium and 65% of dietary vitamin D when compared to the levels taken in the average UK diet.
When comparing the fish intake of the pregnant mothers on SiPS, those consuming the Aquamax salmon took in twenty times more Ω-3 PUFAs, three times more selenium and over thirty times more vitamin D than the mothers who continued their normal diet on the study.
