Final answer:
In the future, the important sources of protein in people's diets may include insects, plant-based proteins, and protein powders.
Step-by-step explanation:
In the future, there are several potential sources of protein that may become increasingly important in people's diets:
- Insects: In many parts of the world, insects are already consumed as a source of protein. More than 2 billion people currently eat insects daily, and this number may increase in the future.
- Plant-based proteins: Plant protein foods contribute over 60% of the per capita supply of protein globally. Sustainability concerns and the need to reduce the reliance on animal-derived foods may lead to a greater emphasis on plant-based protein sources.
- Protein powders: Processed and manufactured protein powders, such as soy and rice protein, are already popular and may continue to gain importance in the future.
