Microalgae as an Alternative Protein Source in Human Nutrition.

Protein is an essential part of the human diet. But with a growing global population and climate emergency, current sources of dietary protein are unable to continue to sustainably meet the global demand. To ensure future food security, new sustainable protein sources are required. Microalgae - a group of plant-like single cells - are thought to be a good option due to their sustainable farming methods and naturally high protein content. Long term health benefits of eating microalgae have been seen in humans. However, the time directly following microalgae ingestion has not been well studied but is an important period when considering a protein source. This research will compare the period after ingestion of three preparations and/or types of microalgae to a traditional source of protein.
