A green microscopic organism could be the next superfood, following in the footsteps of now popular staples like salmon and kale, according to a new study.

Chlorella Vulgaris, or freshwater alga, is a nutrient dense microalga that can be sustainably cultivated, researchers at the University of Birmingham said in their report published in the Journal of Food Science. After evaluating its viability as a food substitute, researchers found that it “shows great potential as a nutritious food ingredient.”
