Let's not forget algae. Solazyme is already producing various food components for food companies, from algae, in highly efficient and dense factories, and at a competitive price.And i think with time it might be a cheap carbohydrates source. And those food components are much better than natural components - because you can tailor the exact chemical composition of them. And with technologies like molecular gastronomy, or making great meat substitutes out of protein(like beyond meat), food components could become the basis for a lot of food variety.
