研究发现摄入高糖饮食或影响大脑中多巴胺的作用_我的网站

A |     At the invitation of Chinese President Xi Jinping, King of the Hashemite Kingdom of Jordan Abdullah II ibn Al Hussein will pay a state visit to China from August 18 to 24, according to Chinese Foreign Ministry on Monday.    This visit marks King Abdullah II's ninth visit to China since his accession to the throne, said foreign ministry spokesperson Lin Jian at a regular press briefing on the same day.    Lin said that during the visit, President Xi will hold talks with King Abdullah II, exchanging their opinions on bilateral relations and international and regional issues of mutual interest. Premier Li Qiang and Chairman of the Standing Committee of the National People's Congress Zhao Leji will meet with him respectively, Lin added.    King Abdullah II will also visit Shanghai and Shenzhen, Lin said.    Noting China and Jordan enjoy traditional friendship, Lin said under the strategic guidance of President Xi and King Abdullah II, China-Jordan relations have maintained steady growth in recent years, with fruitful cooperation across many fields and deepening friendly exchanges between the two countries.    China will work with Jordan to take this visit as an opportunity to jointly enhance political mutual trust, expand mutually beneficial cooperation, promote people-to-people exchanges and deepen collaboration on multilateral occasions, to take the bilateral strategic partnership to a new height and make positive contributions to regional peace, stability, and development, said the spokesperson.                    。    摄入太多糖与一些健康问题有关，包括胰岛素抵抗、2型糖尿病和某些癌症的发展、心脏病风险增加、视力下降等。密歇根大学的新研究发现，它还可能影响大脑中多巴胺的作用。在苍蝇、啮齿类动物和人类的大脑内，有依赖多巴胺这种神经递质来处理甜味食物的神经回路。研究发现，当摄入高糖饮食时，苍蝇大脑中的奖励信号要么延迟，要么减少，削弱了它们对食物的饱腹感，增加了它们的食量。研究人员发现，当这些奖励信号减少时，研究中的苍蝇就不会感到那么满足，最终会连续吃上几个小时......正如预料的那样，吃得太多的苍蝇最后都长胖了。幸运的是，研究发现，用更健康的饮食取代高糖饮食，可以逆转这种抑制作用，神经回路恢复了敏感度，食物消耗最终减少。

B | 这可能有助于解释以下这种情况：许多人报告说，当他们改用像生酮饮食这样的低碳水化合物饮食方案时，他们感到食欲减少。
