Meet the Meat Alternatives: The Value of Alternative Protein Sources

Meat alternatives are non-animal-based proteins with chemical characteristics and aesthetic qualities comparable to meat. The global increase in meat consumption is associated with the adverse environmental impacts such as increased greenhouse gas emissions contributing to global warming and higher water/land use. In this review, we focus on the development, availability, and nutritional value of various meat alternatives and their impact on meat consumption.

Changing dietary patterns and drive for environmental conservation contribute to the recent increase in the consumption of environmental friendly sources of proteins such as plant-based and mycoprotein-based meat alternatives. Perceived lack of naturalness and poor cultural acceptance present as roadblocks for widespread societal acceptance for meat alternatives. Continued research and efforts are needed to make the meat alternatives more aesthetically appealing with improved nutritive value.
