Cornsalad, also known as mâche or lamb's lettuce, is a cold-hardy European green traditionally harvested in winter months. Despite its delicate appearance, this nutrient-dense leafy vegetable delivers remarkable micronutrient concentration per serving. With 2.18 mg of iron per 100g—among the highest in leafy greens—cornsalad supports oxygen transport and mitochondrial function critical for cellular longevity. The 459 mg potassium content aids blood pressure regulation and cardiovascular health, while 38.2 mg vitamin C per 100g supports collagen synthesis and immune resilience. Its mild, slightly nutty flavor and tender texture make it accessible for raw consumption, maximizing retention of heat-sensitive nutrients. The low caloric density (21 kcal/100g) combined with bioavailable micronutrients makes cornsalad an efficient nutrient-per-calorie choice. Traditional use in Mediterranean and Northern European cuisines reflects centuries of nutritional wisdom, while modern research validates its role in cardiovascular and metabolic health optimization for healthy aging.
Iron content (2.18 mg/100g) supports hemoglobin synthesis and mitochondrial cytochrome oxidase function, improving cellular oxygen utilization and aerobic capacity
High potassium-to-sodium ratio (459:4) supports endothelial function and reduces arterial stiffness through potassium's role in vascular smooth muscle relaxation
Vitamin C (38.2 mg/100g) acts as a cofactor for collagen cross-linking and promotes neutrophil function, supporting skin integrity and infection resistance
Selenium (0.9 mcg/100g) is essential for glutathione peroxidase synthesis, a critical antioxidant enzyme protecting cells from oxidative stress and supporting thyroid health
Magnesium (13 mg/100g) and phosphorus (53 mg/100g) support bone mineral density and ATP synthesis for metabolic efficiency
As a raw leafy green with no anti-nutrients or digestive inhibitors, cornsalad is optimal for any meal or eating window. Consumed with meals containing fat improves vitamin A absorption; pairing with vitamin C sources at same meal enhances iron bioavailability.
Fasting-compatible
While compatible with fasting protocols, consuming with a small fat source (nuts, seeds, oil) during eating windows maximizes fat-soluble nutrient absorption. Iron content supports energy; consider midday consumption for sustained metabolic function.
