Perspectives on Future Protein Production.

An increasing world population, rising affluence, urbanization, and changing eating habits are all contributing to the diversification of protein production. Protein is a building block of life and is an essential part of a healthy diet, providing amino acids for growth and repair. The challenges and opportunities for production of protein-rich foods from animals (meat, dairy, and aquaculture), plant-based sources (pulses), and emerging protein sources (insects, yeast, and microalgae) are discussed against the backdrop of palatability, nutrition, and sustainability.
