#83 of 96 in Fruit · scored 66/100
Groundcherries are small, tart berries enclosed in a papery husk, rich in vitamin C and niacin with a unique bioactive compound profile. These nutrient-dense fruits offer antioxidant and anti-inflammatory benefits with minimal calories.
Representative amounts for this food, not measured for this item. Real content varies widely by variety, ripeness and storage.
These are the scored components, not a sum: the published score also reflects normalisation across the catalog, so the parts above will not add to 66.
Groundcherries (Physalis species) are indigenous to Central and South America and have been cultivated for centuries. Despite their modest caloric content (53 kcal per 100g), they deliver substantial micronutrient density, particularly vitamin C (11mg per 100g) and niacin (2.8mg per 100g), making them metabolically efficient. The fruit contains withanolides—steroid lactones also found in ashwagandha—which have demonstrated anti-inflammatory properties in preliminary research. Their tart flavor profile indicates high polyphenol content, supporting antioxidant status. The presence of significant phosphorus (40mg) and iron (1mg) supports bone health and oxygen transport. Groundcherries' low glycemic index due to their carbohydrate composition and negligible fiber notation (likely underestimated in USDA data) makes them suitable for metabolic health. The bioactive compound profile, combined with their traditional use in indigenous medicine systems, positions groundcherries as an emerging longevity food worthy of investigation in aging and inflammation research. Their seasonal availability and distinctive taste make them an accessible functional food for those seeking nutrient density without caloric burden.
Withanolides modulate NF-κB signaling pathways, reducing systemic inflammation; polyphenols provide antioxidant defense against oxidative stress
Vitamin C (11mg/100g) supports T-cell proliferation and antibody production; antioxidants protect immune cells from oxidative damage
Low glycemic load combined with polyphenolic compounds may improve insulin sensitivity and reduce postprandial glucose spikes
Niacin (2.8mg/100g) supports HDL cholesterol and vascular function; polyphenols reduce LDL oxidation
Groundcherries' low sugar content, minimal glycemic impact, and micronutrient density make them suitable across all times. Morning consumption leverages vitamin C for daytime immune support; afternoon provides sustained polyphenol antioxidant benefits. No circadian conflict with digestion or sleep.
