Abstract
The beneficial properties of fatty acids have been undervalued for several years. In contraposition, new studies reveal that fatty acids have an essential role for human health. The aim of the study is to demonstrate the clinical applications of fatty acids present in sea buckthorn oil. The composition of fatty acids found in sea buckthorn (Hippophae rhamnoides) oil is unique for this species, presenting a vast range of health benefits for humans and therefore it is highly valued by both biomedicine and the cosmetic industry. In this way, we will see the clinical effect of monounsaturated, polyunsaturated and saturated fatty acids that constitute sea buckthorn oil and how they contribute to the correct function of the organism. Despite there being studies that support the positive effects of sea buckthorn fatty acids, they are limited. Hence, most of the results obtained in this review are from studies of isolated fatty acids instead of fatty acids extracted from sea buckthorn oil. These facts permit to demonstrate the effect of sea buckthorn fatty acids separately but we lost the possibility of detecting a synergic effect of all of them. More studies are necessary to certify the clinical application of the fatty acids present in sea buckthorn oil as well as discovering possible synergies between them.
Highlights
For several decades, the beneficial properties of fatty acids have been largely ignored
33 articles were excluded due to the fact that they did not focus on the fatty acids of sea buckthorn oil [10] and that they were written in Chinese [2]
For the sake of clarity, the present review has been structured in three main parts, covering the three fatty acids found in sea buckthorn oil: firstly, monounsaturated fatty acids omega-7 and omega-9, polyunsaturated fatty acids omega-3 and omega-6, and the saturated fatty acids
Summary
The beneficial properties of fatty acids have been largely ignored. Fatty acids have an important role in several metabolic and structural functions. They are indispensable compounds of the cell membranes, are responsible for the transport of vitamins, and regulate the concentration of lipids in plasma. Fatty acids produce a number of precursors such as eicosanoides, decosanoides, steroid hormones and biliary acid, all of them fundamental for the adequate functioning of the metabolism. They are the most important energetic nutrient –it is currently recommended that at least 20% of the total energy intake should derive from lipids–
