This study was a part of the EU supported research project Inuedo [ 25] with the main objective to elucidate the fertility in European and Inuit groups with different intake of POPs [ 26, 27].
More research into the effect of total protein intake in different populations with intakes of protein from different sources is needed to establish the effects of total protein intake and differing sources on diabetes risk.
Energy intake was calculated for the substitution scenario in order to examine whether the scenario based upon replacement of foods by low-sodium alternatives might result in different energy intakes.
"If you hold all schools accountable in the same way in spite of their vastly different intakes, you are holding them accountable for something that society can't solve and the system implodes".
Reasons for the inconsistent results in Asians may be related, in part, to the traditionally low alcohol intake in this population, the variable definition of alcohol intake in different studies, and often, the limitation of the assessment to current alcohol intake.
The CP and TDN intake in different groups was also not affected due to similar intake and digestibility of nutrients.
From the identified studies and respective populations we recorded publication reference, total number of participants, country, sex, age (mean, median, or range), recruitment time, follow-up (years), outcome reported (stroke, cardiovascular disease) and method of outcome assessment, number (rate) of events, method of assessing salt intake, and level of salt intake in different categories.
We performed post-hoc subgroup analyses by the percentage of protein intake in higher-protein diets to explore whether diets with a higher versus lower percentage protein intake resulted in different outcomes (that is, percentage protein intake >30% versus, 20 30%, versus <20%).
In addition to calculating intake in different formats the studies also grouped foods differently.
