![]() ![]() Moreover, phenolic compounds, including flavonoids, were also detected in poppy seeds 8, 9.Ĭold-pressed vegetable oils are becoming more and more popular due to their minimal processing, which is considered the basis of a healthy diet, and poppy seed oil also fits into this trend 10. Poppy seed oil also contains a significant amount of tocopherols (up to 340 mg/kg), including mainly γ-tocopherol, some amount of phytosterols (approx. The protein quality of the seeds is relatively high containing all essential amino acids with tryptophan as the limiting amino acid 8. The other fatty acids present in the oil in larger quantities are palmitic acid (14%) and oleic acid (11%) that represent saturated and monounsaturated fatty acids (SFAs and MUFAs), respectively. The oil extracted from the seeds predominantly contains polyunsaturated fatty acids (PUFAs) with linoleic acid (18:2 n−6) as the main fatty acid (60–70%) 7, 8. ![]() The main components of poppy seeds are fat (40–50%), dietary fibre (20–30%), mainly its insoluble fraction, and protein (10–20%) 7, 8. The popularity and use of poppy seeds varies depending on the part of the world, for example poppy seed noodles are a traditional dish in Poland and other Central European counties, and poppy seed pastes are made in Turkey and other Western Asian countries 6. Bread, sweets and confectionery products, such as cakes, pancakes, muffins or cookies, may contain poppy seeds in different quantities, from a small decorative addition to bread to the main ingredient of poppy seed cake (makowiec in Polish). Poppy seeds meet consumers’ preferences and are eaten in various forms, either whole or ground, and added to retailed food products or regional dishes, such as poppy seed noodles or pastes. ![]() Poppy seeds, in turn, are the source of nutrients and other bioactive compounds 3 and usually do not contain alkaloids, unless contaminated with them 4, 5. Opium poppy contains specific alkaloids, including the most known morphine, obtained from the seed capsules of this plant 1, 2. Opium poppy ( Papaver somniferum L.) is a flowering plant widely known for its culinary and pharmacological uses. In conclusion, a low and regular consumption of partially defatted poppy seeds may be beneficial in managing obesity-related disorders. Only dietary supplementation with partially defatted poppy seeds attenuated visceral fat and hepatic triglyceride accumulations and lowered blood triglyceride concentrations, and at the transcriptional level, the inhibition of SREBP-1c, which upregulates genes responsible for de novo lipogenesis, was additionally observed in this organ. Both dietary seed forms increased cholesterol accumulation in the liver. In the distal intestine, both dietary seed forms stimulated microbial acetate production, and the supplementation with partially defatted poppy seeds additionally inhibited isobutyrate and isovalerate formation, which indicates a reduction in putrefaction. However, depending on the seed form, dietary supplementation with poppy seeds differentially affected the microbial and endogenous lipid metabolism in rats. The rats fed with a high-fat diet were characterised by severe metabolic disorders, especially in the liver, and poppy seeds were unable to prevent them. The defatted poppy seeds had, among others, lower fat content and higher fibre and protein content than native poppy seeds. The aim of this study was to compare the effects of dietary supplementation with a small amount of native or partially defatted poppy seeds on gastrointestinal function and lipid metabolism in rats fed a high-fat diet. Partially defatted poppy seeds, a by-product of poppy oil cold pressing, could be an interesting dietary supplement for obesity management. ![]()
