To test the viability of the Mediterranean diet as an affordable low-energy-density model for dietary change.
Foods characteristic of the Mediterranean diet were identified using previously published criteria. For these foods, energy density (kJ/100 g) and nutrient density in relation to both energy ($/MJ) and nutrient cost were examined.
Some nutrient-rich low-energy-density foods associated with the Mediterranean diet were expensive, however, others that also fit within the Mediterranean dietary pattern were not.
The Mediterranean diet provides a socially acceptable framework for the inclusion of grains, pulses, legumes, nuts, vegetables and both fresh and dried fruit into a nutrient-rich everyday diet. The precise balance between good nutrition, affordability and acceptable social norms is an area that deserves further study. The new Mediterranean diet can be a valuable tool in helping to stem the global obesity epidemic.
检验地中海饮食作为一种经济实惠的低能量密度饮食模式进行饮食改变的可行性。
使用先前发表的标准来确定地中海饮食中特有的食物。对于这些食物，我们检查了与能量（$/MJ）和营养素成本相关的能量密度（kJ/100g）和营养素密度。
与地中海饮食相关的一些营养丰富但能量密度低的食物价格昂贵，但也有一些其他符合地中海饮食模式的食物价格并不昂贵。
地中海饮食为在日常饮食中纳入谷物、豆类、豆类、坚果、蔬菜以及新鲜和干果提供了一个社会可接受的框架。良好的营养、可负担性和可接受的社会规范之间的精确平衡是一个值得进一步研究的领域。新的地中海饮食可以成为帮助遏制全球肥胖流行的有力工具。
