 Takeda Consumer Healthcare Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, President Mari Nogami, hereinafter "Takeda Consumer Healthcare") and Euglena Co., Ltd. (Headquarters: Minato-ku, Tokyo, President Mitsuru Izumo, hereinafter "Euglena Co., Ltd." ”) Is a powder of the microalga Euglena (Japanese name: Euglena) (hereinafter referred to as Euglena powder) in a joint research with Associate Professor Takeshi Tsuzuki in the field of food chemistry, Department of Food Function and Health Science, Graduate School of Agriculture, National University Corporation. ) And vegetable powder were ingested at the same time, and we are pleased to inform you that we have confirmed the research results suggesting an anti-obesity effect in obese model mice.
 In addition, Takeda Consumer Healthcare and Euglena Co., Ltd. have entered into a comprehensive alliance agreement to jointly consider the possibility of developing new products containing Euglena.

■ Background and purpose
 In recent years, an increasing number of people have become obese due to the accumulation of body fat due to changes in eating habits and lack of exercise. Obesity is regarded as a risk factor for myocardial infarction and stroke, and countermeasures are required. In addition, it is thought that chronic inflammation occurs in adipose tissue during obesity, which adversely affects the whole body. On the other hand, short-chain fatty acids intestinal flora produced, via the receptors on the host side of the cell has been shown to suppress the obesity, the previous joint research *1 in mice of the normal diet fed , It has been reported that Euglena powder and vegetable powder exhibits an inhibitory effect on visceral fat accumulation and an anti-inflammatory effect *3​ ​through regulation of the intestinal flora *2.
 In this study, obese model mice fed a high-fat diet were fed with paramilon powder, Euglena powder, and Euglena powder and vegetable (barley young leaves, tomorrow's leaves, kale) rich in water-soluble dietary fiber, and fed a normal diet. We evaluated whether the effects observed in the domestic mice could be confirmed in the obese model mice.

■研究内容と結果
 マウスを、①通常食を与えたマウス群(以下通常食群)、②高脂肪食を与えたマウス群(以下高脂肪食群)、③高脂肪食とパラミロン粉末を与えたマウス群(以下高脂肪食+パラミロン粉末群)、④高脂肪食とユーグレナ粉末を与えたマウス群(以下高脂肪食+ユーグレナ粉末群)、⑤高脂肪食とユーグレナ粉末と野菜粉末の混合物を与えたマウス群(以下高脂肪食+ユーグレナ粉末+野菜粉末群)の5つに分け、2ヵ月間経口摂取させました。

 As a result, the peri-adipose tissue weight and total white adipose tissue weight were significantly reduced in the high-fat diet + paramylon powder group, high-fat diet + Euglena powder group, and high-fat diet + Euglena 1 and Table 1). Furthermore, compared to the high-fat diet + paramylon powder group Euglena powder + vegetable powder group, and the simultaneous intake of vegetable powder enhances the effect of paramylon powder intake. It was confirmed (Fig. 1 and Table 1).

 In addition, a significant decrease in the area of adipose tissue around the testis was confirmed in the high-fat diet + Euglena

Figure 2

 Then, in the obese model mice, the high-fat diet + paramylon powder group, the high-fat diet + Euglena powder group and the high-fat diet + Euglena powder + vegetable powder group were compared with the high-fat diet group, and inflammatory cytokines * in the serum. We confirmed a significant decrease in IL-6, which is 4. Furthermore, it was confirmed that the high-fat diet + Euglena powder group and the high-fat diet + Euglena powder + vegetable powder group significantly enhanced the IL-6-reducing effect as compared with the high-fat diet + paramilon intake group. In the fat diet + Euglena powder + vegetable powder intake group, a significant decrease in IL-1b was confirmed compared to the high-fat diet group (Fig. 3). As a result, the anti-inflammatory effect (significant decrease in inflammatory cytokines IL-6 and IL-1b) obtained in the normal diet-fed mice in the previous joint study can be confirmed in the obese model mice by this study. It will be.

 さらに、前回の共同研究で、通常食飼育マウスのユーグレナ粉末の摂取およびユーグレナ粉末と野菜粉末の同時摂取により、腸内細菌叢が改善することを報告しましたが、高脂肪食を与えた今回の試験においても、高脂肪食+ユーグレナ粉末+野菜粉末群の混合物を摂取したマウスにおいて、腸内細菌叢が産生する短鎖脂肪酸(プロピオン酸)の有意な増加(図4)と、有害菌の減少を確認しました。

 From these results, Euglena powder and vegetable powder contributed to the anti-obesity effect through the improvement of the intestinal flora and the suppression of inflammation seen from the decrease of inflammatory cytokines. The results of this research were published in the online scientific journal "Nutrients" on January 21st.
