This supports the idea that a throughout definition of MD must consider not only the types of food but also their amounts and frequency of consumption.
The Special Issue also included other aspects relating to the MD, such as serving size and translation of the MD to other diets. Firstly, D’Alessandro and coworkers performed a systematic review of dose-response meta-analyses of prospective studies, which evaluated the association between the intake of food groups belonging to a variant of the Modern Mediterranean Diet Pyramid and the risk of CVD [ 25]. Among the different aspects worth to be studied, the serving sizes of the foods seems to have a key role in order to obtain a protective or a not detrimental effect toward selected diseases. This supports the idea that a throughout definition of MD must consider not only the types of food but also their amounts and frequency of consumption. Being the efficacy and feasibility of MD for the management of chronic diseases not been extensively evaluated in non-Mediterranean settings, the paper by George and coworkers [ 26] increased knowledge about potential strategies for translating the traditional MD into a non-Mediterranean setting.
