Do you know what characterises a real nut?

In botanical terms, a wide variety of kernels, pulses and drupes such as almonds and pecan nuts, or capsule fruits such as the Brazil nut, are popularly – and erroneously – considered to be nuts. A real nut is characterised by a lignified pericarp which contains a single seed kernel – the nut. Two variants that have truly earned this appellation are hazelnuts and chestnuts. Because of their high magnesium and vitamin B content, chestnuts can be considered to constitute ideal “nerve nutrition”. Furthermore, their fibre content stimulates digestion and the vitamins C and E, being free radical inhibitors, protect somatic cells.
