Food in season: Peas
The pea is a type of legume which has been grown by man since the Bronze Age. Historically, legumes have been associated with cultures within which people regularly attained great ages (such as the Japanese, with a soya and tofu-rich diet), and a recent study conducted under the auspices of the World Health Organisation found that eating legumes such as peas was the most important dietary predictor of survival in old age, with a 7-8% reduction in mortality hazard ratio for every 20g increase in daily legume intake.
