A review of nutritional properties and health benefits of Physalis species

Plant Foods Hum Nutr. 2020 Sep;75(3):316-325. doi: 10.1007/s11130-020-00821-3.

Abstract

The Physalis genus of the Solanaceae family is home to many edible food crops including tomatillo, goldenberry, and groundcherry. These Physalis members have garnered more attention as consumer interest in novel fruits and vegetables has increased because of increasing awareness of the health benefits of eating a diverse diet. As a result of this interest, several preliminary studies were conducted of these Physalis to evaluate their nutritional and chemical profiles associated with health benefits. Results showed these crops contain many essential minerals and vitamins, notably potassium and immune system supporting Vitamin C, also known for its antioxidant activity. Beyond nutritional properties, these crops also contain a class of steroidal lactones called withanolides, which have been recognized for their antitumor, and antinflammatory properties. In some studies, withanolide extract from Physalis species have exhibited cytotoxicity towards cancers cells. Overall, this review focuses on the nutritional and physiochemical properties of tomatillo, goldenberry, and groundcherry and how they relate to human health.
