正常人的食物摄入量已在实验室和自然环境中自由生活条件下进行了研究。对于现实世界摄入量的测量，饮食日记技术并不完善，并且往往会低估实际摄入量，但它似乎很敏感，可以检测对饮食行为的微妙影响，并产生可靠有效的测量结果。现实世界的研究显示自然环境的多元丰富性，可以调查摄入调节的复杂性，甚至可以调查因果关系。现实世界的研究可以克服实验室研究的一些弱点，即对饮食的限制常常被消除或缺失，对饮食的促进性影响往往被控制或消除，变量的重要性可能被高估，并且由于研究持续时间短而可能错过重要的影响。现实世界的研究表明，一系列广泛的生理、心理和社会变量可能对摄入量产生强大而直接的影响。补偿机制（包括一些延迟 2 至 3 天运行的机制）会根据之前的过度行为进行调整。遗传影响食物摄入调节的各个方面，从体型的决定到个人偏好和社会倾向的微妙性，以及环境因素影响个人的程度。因此，现实世界的研究提供了宝贵的教训，并且需要更多的东西来补充实验室研究。营养 2000；16：800-813。 (C) 爱思唯尔科学公司。2000。
Food intake by normal humans has been investigated both in the laboratory and under free-living conditions in the natural environment. For measurement of real-world intake, the diet-diary technique is imperfect and tends to underestimate actual intakes but it appears to be sensitive, can detect subtle influences on eating behavior, and produces reliable and valid measures. Research studies in the real world show the multivariate richness of the natural environment, which allows investigation of the complexities of intake regulation, and even causation can be investigated Real-world research can overcome some of the weaknesses of laboratory studies, where constraints on eating are often removed or missing, facilitatory influences on eating are often controlled or eliminated, the importance of variables can be overestimated, and important influences can be missed because of the short durations of the studies. Real-world studies have shown a wide array of physiologic, psychological, and social variables that can have potent and immediate effects on intake. Compensatory mechanisms, including some that operate with a 2- to 3-d delay, adjust for prior excesses. Heredity affects all aspect of food-intake regulation, from the determination of body size to the subtleties of the individual preferences and social proclivities and the;extent to which environmental factors affect the individual. Hence, real-world research teaches valuable lessons, and much morels needed to complement laboratory studies. Nutrition 2000;16: 800-813. (C) Elsevier Science Inc. 2000.
