脂肪的高适口性的潜在机制可以通过回顾奖励行为期间脂肪检测和大脑模式的动物研究来评估。脂肪酸可能被味蕾上的受体识别,信号通过味觉神经传递到大脑。摄入的油在胃肠道中被分解和吸收,胃肠道也通过未知的机制向大脑发送信号。来自感觉受体和外周组织的信息被大脑整合,通过奖励系统产生对脂肪食物的强烈食欲。了解脂肪识别的机制将被证明是有价值的策略,以管理食品的高适口性的发展。
Potential mechanisms underlying the high palatability of fat can be assessed by reviewing animal studies on fat detection and brain patterns during reward behavior. Fatty acids are likely recognized by receptors on taste buds, with the signals transmitted to the brain through taste nerves. Ingested oil is broken down and absorbed in the gastrointestinal tract, which also sends signals to the brain through unknown mechanisms. Information from both sensory receptors and peripheral tissue is integrated by the brain, resulting in a strong appetite for fatty foods via a reward system. Understanding mechanisms of fat recognition will prove valuable in the development of strategies to manage the high palatability of foods.
