"The case for Golden Rice is pure hype. For Golden Rice is not particularly rich in carotene and in any case, rice is not, and never will be, the best way to deliver it. Carotene is one of the commonest organic molecules in nature. It is the yellow pigment that accompanies chlorophyll in all dark green leaves (the many different kinds known as “spinach” are a great source) and is clearly on show in yellow roots such as carrots and some varieties of cassava, and in fruits like papaya and mangoes that in the tropics can grow like weeds."
