Numerous studies showed that seasonality plays a key role in optimizing the antioxidant properties of fruits and vegetables. For example, a recent Chinese study have investigated the influence of growing season (summer vs winter) on the synthesis and accumulation of phenolic compounds and antioxidant properties in five grape cultivars. The study showed that both phenolic compounds and antioxidant properties in the skin and seed of winter berries were significantly higher than those of summer berries for all of the cultivars investigated. Finally, to choose seasonal vegetables and fruits also ensures considerable saving of money.
