“…In comparison to the present study, Szlinder-Richert et al (2011) found lower amounts for the same fat soluble vitamins -7.69 µg/100 g ww for retinol, 7.46 µg/100 g ww for cholecalciferol, and only 280 µg/100 g ww for α-tocopherol in raw edible carp tissue. Ostermeyer and Schmidt (2006) studied cholecalciferol content in farmed Carp fish fillets. The result is considerably low (0.98 µg/100 g ww) compared to the presented data.…”

“…Only vitD3 has been included in the majority of studies, as quantification of 25OHD3 has been an analytical challenge. Data for vitD content in raw samples of farmed salmon and farmed trout are scarce, and primarily analysed for food databanks [15,17,[23][24][25][26][27][28][29]. The sampling system is therefore systematic to cover the market in the specific countries i.e.…”

Fatty fish are generally stated as having high vitamin D content and among these are salmon and trout. In the aquaculture industry of salmonids the two main species produced are Salmo salar (Atlantic salmon) and Onchorhynchus mykiss (rainbow trout). Published data have shown lower content of vitamin D in farmed than in wild species, but generally data on vitamin D in farmed salmon and rainbow trout are scarce. In commercial production facilities we aimed to study the variation of vitamin D in farmed salmon and rainbow trout prepared for sale to consumer. Thirteen organically produced salmon and 18 rainbow trout were sampled within the range 0.7-4.0 kg of gutted weight. All fish were ready for consumption, and analysed for content of vitamin D3, 25-hydroxyvitamin D3, and fat.Mean vitamin D3 content in salmon and rainbow trout was 1.6 ± 0.5, and 5.0 ± 2.3 µg/100 g, respectively. Compared to vitamin D3, the content of 25-hydroxyvitamin D3 was 11% and 3%, respectively. In farmed salmon a linear relationship with vitamin D3 being dependent on weight (P<0.05) as well as to fat content (P<0.05), while no similar relationship was found for farmed rainbow trout. Despite this, both species exhibit a linear correlation between fat and gutted weight (P<0.001).The results indicate that there is a difference in the storage of vitamin D between the two salmonids, as 25-found in the salmonids is challenging farmed salmon and farmed trout as an essential vitamin D source.

“…This wide vitamin A to vitamin D ratio range is the reason why fish liver oils often need further processing. In fresh fish products we observe a huge variation in the vitamin D 3 content per 100 g wet weight (Egaas and Lambertsen, 1979; Takeuchi et al, 1984, 1986; Kobayashi et al, 1995; Mattila et al, 1995a, 1997; Ostermeyer and Schmidt, 2006; Lu et al, 2007; Byrdwell et al, 2013) (Table 1). Large variations in vitamin D 3 content were found within the same species, but also between the different fish species.…”

Vitamin D is a micronutrient that is needed for optimal health throughout the whole life. Vitamin D3 (cholecalciferol) can be either synthesized in the human skin upon exposure to the UV light of the sun, or it is obtained from the diet. If the photoconversion in the skin due to reduced sun exposure (e.g., in wintertime) is insufficient, intake of adequate vitamin D from the diet is essential to health. Severe vitamin D deficiency can lead to a multitude of avoidable illnesses; among them are well-known bone diseases like osteoporosis, a number of autoimmune diseases, many different cancers, and some cardiovascular diseases like hypertension are being discussed. Vitamin D is found naturally in only very few foods. Foods containing vitamin D include some fatty fish, fish liver oils, and eggs from hens that have been fed vitamin D and some fortified foods in countries with respective regulations. Based on geographic location or food availability adequate vitamin D intake might not be sufficient on a global scale. The International Osteoporosis Foundation (IOF) has collected the 25-hydroxy-vitamin D plasma levels in populations of different countries using published data and developed a global vitamin D map. This map illustrates the parts of the world, where vitamin D did not reach adequate 25-hydroxyvitamin D plasma levels: 6.7% of the papers report 25-hydroxyvitamin D plasma levels below 25 nmol/L, which indicates vitamin D deficiency, 37.3% are below 50 nmol/Land only 11.9% found 25-hydroxyvitamin D plasma levels above 75 nmol/L target as suggested by vitamin D experts. The vitamin D map is adding further evidence to the vitamin D insufficiency pandemic debate, which is also an issue in the developed world. Besides malnutrition, a condition where the diet does not match to provide the adequate levels of nutrients including micronutrients for growth and maintenance, we obviously have a situation where enough nutrients were consumed, but lacked to reach sufficient vitamin D micronutrient levels. The latter situation is known as hidden hunger. The inadequate vitamin D status impacts on health care costs, which in turn could result in significant savings, if corrected. Since little is known about the effects on the molecular level that accompany the pandemic like epigenetic imprinting, the insufficiency-triggered gene regulations or the genetic background influence on the body to maintain metabolic resilience, future research will be needed. The nutrition community is highly interested in the molecular mechanism that underlies the vitamin D insufficiency caused effect. In recent years, novel large scale technologies have become available that allow the simultaneous acquisition of transcriptome, epigenome, proteome, or metabolome data in cells of organs. These important methods are now used for nutritional approaches summarized in emerging scientific fields of nutrigenomics, nutrigenetics, or nutriepigenetics. It is believed that with the help of these novel concepts further understanding can be generated to develop f...
