It reminds me of soylent, which used algae oil with the hope that algae can be produced in bioreactors to produce protein and fat. The algae successfully created algae oil (fat) but unfortunately a few people got diarrhoea from it, so soylent got rid of algae oil in the next version. As for protein, currently the most efficient form of protein is soy protein. Global hunger is the result of animal agriculture because meat is inefficient. It takes about 10 kg of feed to produce about 1 kg of beef. There is a huge loss of energy thanks to the energy needed to keep the cow alive (e.g. keep its blood warm). There is more than enough food to feed the world but because most of the food grown is fed to livestock, this is what contributes to world hunger. The answer to transition to a vegan diet.
