Description

本発明は、PYY分泌促進剤に関する。   The present invention relates to a PYY secretion promoter.

ペプチドYY(PYY)は1968年にブタの小腸より単離されたペプチドで、ニューロペプチドY(NPY)、膵ポリペプチド(PP)とともに一つのペプチドファミリーを形成している。PYYは、おもに下部消化管(回腸および結腸)の粘膜層内細胞から食後分泌される。PYYの末梢投与は膵外分泌および腸運動を抑制させることが知られている(非特許文献1、2)。これまでの研究によって、PYYの分泌を促進するものとして、レジスタントスターチ、ラクチトール及びβ−グルカンが知られている(非特許文献3、4)。
しかしながら、これらの物質のPYY分泌促進作用は十分なものとはいえない。
Peptide YY (PYY) is a peptide isolated from the small intestine of pigs in 1968, and forms one peptide family together with neuropeptide Y (NPY) and pancreatic polypeptide (PP). PYY is secreted postprandial mainly from cells in the mucosal layer of the lower gastrointestinal tract (ileum and colon). It is known that peripheral administration of PYY suppresses pancreatic exocrine secretion and intestinal motility (Non-patent Documents 1 and 2). As a result of studies so far, resistant starch, lactitol and β-glucan are known to promote the secretion of PYY (Non-patent Documents 3 and 4).
However, the PYY secretion promoting action of these substances is not sufficient.

一方、アルギン酸又はその塩は、食品の増粘剤や歯科印象剤のゲル化剤として広く使用されており、また、アルギン酸塩の1種類であるアルギン酸カリウムを用いた動物実験で、ナトリウムイオンの吸着能が他の多糖類よりも高いことを見いだし、実際にアルギン酸カリウムを摂取させることで体内のナトリウムが排出され、その結果高血圧の抑制に効果があることが報告されている(非特許文献5)。また、アルギン酸塩のうち、アルギン酸カリウムが消化管ホルモンの1種であるGIP分泌抑制作用を有することが知られている(特許文献1)。
また、促進された満腹効果を有する食品組成物として、タンパク質とバイオポリマー増粘剤を配合した食品組成物が知られており、バイオポリマー増粘剤としてアルギナート(アルギン酸塩)が例示され、分子量範囲が20万〜40万であることが好ましい旨の記載がある(特許文献2及び3)。
On the other hand, alginic acid or a salt thereof is widely used as a thickener for foods or a gelling agent for dental impression agents. In addition, sodium ions are adsorbed in animal experiments using potassium alginate, which is a kind of alginate. It has been found that the ability is higher than that of other polysaccharides, and when sodium alginate is actually ingested, sodium in the body is excreted, and as a result, it is effective in suppressing hypertension (Non-patent Document 5). . Moreover, it is known that among alginate, potassium alginate has a GIP secretion inhibitory action which is one kind of gastrointestinal hormone (Patent Document 1).
In addition, as a food composition having an accelerated satiety effect, a food composition containing a protein and a biopolymer thickener is known, and alginate (alginate) is exemplified as a biopolymer thickener, and its molecular weight range Is preferably 200,000 to 400,000 (Patent Documents 2 and 3).

しかしながら、アルギン酸又はその塩が、ヒトのPYY分泌に対してどのような作用を及ぼすかについては全く知られていない。   However, it is not known at all what effect alginic acid or a salt thereof has on human PYY secretion.
