Abstract
Mushrooms are the gifts of the non-green revolution; they are not limited by land demand or specific growth requirements. Nearly 14,000 species of mushrooms are on record thus far; of these, only 2200 species are deemed edible. Only 650 species from this list have been cultivated and consumed. Farmed on waste, mushrooms are rich reservoirs of proteins, polysaccharides, metabolites, minerals and vitamins. In the following review, various edible mushrooms have been listed and their nutritional aspects and their associated contributions have been discussed. Furthermore, the commercial mushroom-based products that are on the market have been surveyed. The challenges facing the use of mushroom and mushroom products as foods, functional foods and nutraceuticals have been presented. The need to seek options to troubleshoot the current limitations has also been discussed.
