Animal vs. Plant-Based Proteins

There is currently a trend in replacing animal proteins with plant proteins by shifting towards a more plant-based diet, as promoted in Western countries. However, such reduction may not only impair protein adequacy, but also the adequacy in other nutrients.

 

 

In a newly concluded study, linear programming optimization was used to assess the minimum protein level (Model Set#1) and the minimum animal protein contribution to total proteins (Model Set#2) that are compatible with the fulfilment of all nutrient-based recommendations.[1] 

Five French subpopulations were included. The findings showed that the animal protein contribution to total proteins compatible with meeting all nutrient-based recommendations at no additional cost varies between 45% and 60% depending on the group of adults considered.[1] The authors concluded that total replacement of animal proteins with plant proteins may lead to protein inadequacy if additional cost is not available to supplement the shortfall.
