Body size and body composition have been suggested as the best explanation for the temporal trend toward early menarche over the last 100 years. There is evidence from human and animal studies that indicates that body size is not the primary factor in influencing the occurrence of menarche. The data actually show that diet may be a primary environmental control mechanism of menarche especially since it alters hormone levels. We see diet as an etiological factor in both the long term and immediate control of menarche. In the long term it influences body size and development leading to menarche. In the short term it acts at a critical state to precipitate the onset of menarche and related physiological changes. This hypothesis does not exclude other less important factors associated with menarche. Our data shows that the present trend toward early menarche can be reversed when a balanced vegetarian diet is selected in place of the ordinary American diet.
身体大小和身体组成被认为是过去100年来初潮提前这一长期趋势的最佳解释。来自人类和动物研究的证据表明，身体大小并非影响初潮发生的主要因素。实际数据显示，饮食可能是初潮的主要环境控制机制，尤其是因为饮食会改变激素水平。我们认为饮食在初潮的长期和即时控制中都是一个病因因素。从长期来看，它影响身体大小和发育，从而导致初潮。从短期来看，它在关键阶段起作用，促使初潮及相关生理变化的开始。这一假设并不排除与初潮相关的其他不太重要的因素。我们的数据表明，当选择均衡的素食饮食来取代普通的美国饮食时，目前初潮提前的趋势是可以逆转的。
