Description

本発明はスフィンゴシン類縁体を含有する食品に関する。   The present invention relates to foods containing sphingosine analogs.

皮膚の角質層は、体内からの水分の蒸散を抑制するとともに、外界からの刺激を防ぐバリア機能を有している。このバリア機能が、紫外線、界面活性剤、乾燥、機械的刺激、活性酸素、水道水中の残留塩素等により損なわれると、乾燥肌、アトピー性皮膚炎、肌あれ等を誘発することが知られている。   The stratum corneum of the skin has a barrier function that prevents transpiration of moisture from the body and prevents irritation from the outside world. It is known that when this barrier function is impaired by ultraviolet rays, surfactants, drying, mechanical stimulation, active oxygen, residual chlorine in tap water, etc., it induces dry skin, atopic dermatitis, skin roughness, etc. Yes.

従来、当該バリア機能を改善する手段としては、アルニカ、ウコン等の植物成分(例えば、特許文献1参照)やパマキン、パヒマラン等の多糖類(例えば、特許文献2参照)を外用投与する方法が報告されている。また、セラミドの経口摂取により、皮膚の水分保持機能が改善されることが報告されている(例えば、非特許文献1参照)。   Conventionally, as a means for improving the barrier function, a method of externally administering a plant component such as Arnica or Turmeric (for example, see Patent Document 1) or a polysaccharide such as Pamakin or Pahimaran (for example, see Patent Document 2) has been reported. Has been. In addition, it has been reported that oral intake of ceramide improves the water retention function of the skin (for example, see Non-Patent Document 1).

しかし、外用投与製剤は、連日全身に適用することは困難であり、また、炎症、刺激、アレルギー等引き起こす場合もある。一方、経口摂取によれば、手軽に全身へ適用することが可能であるが、セラミドの経口摂取では、必ずしも効果が十分であるとはいえない。
従って、経口摂取することにより皮膚の保湿・保護機能を十分に発揮させる方法が望まれている。
However, preparations for external administration are difficult to apply to the whole body every day, and may cause inflammation, irritation, allergies, and the like. On the other hand, oral ingestion can be easily applied to the whole body, but ceramide oral ingestion is not necessarily effective.
Therefore, there is a demand for a method for sufficiently exerting the skin moisturizing / protecting function by ingestion.

一方、スフィンゴシン類は、皮膚に塗布した場合に、しわの発生抑制及びしわの消滅に効果があることが報告されている(例えば、特許文献3参照)。しかしながら、スフィンゴシン類にバリア機能の改善や保湿作用があることは知られておらず、また、これらを経口摂取することも全く報告されていない。

On the other hand, it has been reported that sphingosines are effective in suppressing wrinkle generation and wrinkle disappearance when applied to the skin (see, for example, Patent Document 3). However, it is not known that sphingosines have an improved barrier function or a moisturizing action, and there has been no report of taking them orally.
