A new chapter for CAST
CAST is evolving. We’re building a stronger, smarter, more connected community—where members shape science, students grow as leaders, and agricultural knowledge feeds the future.
Supporting science since 1972.
The Council for Agricultural Science and Technology (CAST) is a nonprofit organization composed of scientific societies and many individual, student, company, nonprofit, and associate society members. Together, we assemble, interpret, and communicate credible, science-based information.

CAST members help us address some of the most important issues that impact our planet, such as how to feed the world’s population, water and soil conservation, and much more.
CAST convenes and coordinates networks of experts to assemble, interpret, and communicate credible, unbiased, science-based information to policymakers, the media, the private sector, and the public. Our primary work is the publication of task force reports, commentaries, special publications, and issue papers written by volunteer experts—economists, legal experts and scientists from many disciplines.
Protein is essential for human health, yet the way it is produced and consumed intersects with global challenges—nutrition, food security, sustainability, and equity. No single protein source perfectly meets human amino acid needs, and relying exclusively on either plant or animal proteins can lead to nutritional gaps or unintended consequences. This paper provides evidence-based guidance on combining complementary protein sources to achieve balanced diets while considering environmental impacts. By understanding protein quality, digestibility, and nutrient density, stakeholders can make informed decisions that promote health and sustainability worldwide.
