The annual commemoration of anti-fascist volunteers who fought fascism in Spain now includes a key contribution from Italian comrades

THE taste of food is something that seems fundamental. In Marx’s view, expressed in A Contribution to the Critique of Political Economy (1859), a physical property like taste provides a measure of the use-value of a commodity as distinct from its exchange-value: “From the taste of wheat, it is not possible to tell who produced it, a Russian serf, a French peasant or an English capitalist.”
Today, humanity consumes nearly 800 million metric tons of wheat a year. Other foods such as potatoes, rice, and different cereal crops are essential to diets around the world.
All of these contain large amounts of carbohydrates in the form of starch molecules. These molecules were made by the plants as an energy store. When plants photosynthesise, they use sunlight to convert water and carbon dioxide into glucose molecules.
Science has always been mixed up with money and power, but as a decorative facade for megayachts, it risks leaving reality behind altogether, write ROX MIDDLETON, LIAM SHAW and MIRIAM GAUNTLETT
