3. Bugs and insects
Insects and bugs are a key protein source for cultures in many parts of the non-Western world and this trend is starting to show up in the US. Promoting them as "Super foods", Don Bugito
has created snackable treats made from crickets and mealworms. And the Newport Jerky Company
sells a range of bug-based products, marketing them as "Natural" and "Paleo". When you're ready to try them, you can even buy them on Amazon.4. Plant-based protein
While similar to #1, plant-based protein isn't seeking to look and taste like meat, but replace it, nutritionally, with plant-based ingredients. Pea protein is one example that you might see at the moment. There is some unique research going into this too--Sustainable Bioproducts
is investigating how to make a complete protein from microbes that live in harsh environments like volcanoes.
