Celtuce (Lactuca sativa var. angustana), also called stem lettuce or Chinese lettuce, is a nutrient-dense brassica relative originating in East Asia. Unlike conventional lettuce, celtuce develops an edible thickened stem prized for its crisp texture and mild flavor. With only 18 calories per 100g and exceptional micronutrient density, celtuce offers particular value for longevity-focused diets. Its potassium content (330mg/100g) supports cardiovascular function and blood pressure regulation—critical for healthy aging. The vegetable provides meaningful folate (46mcg/100g), essential for one-carbon metabolism, DNA synthesis, and homocysteine reduction, all markers of cardiovascular and cognitive health. Celtuce also contains bioactive compounds including lactucin and lactucopicrin (sesquiterpene lactones), which preliminary research suggests may have mild sedative and anti-inflammatory properties. Its high water content (95%) combined with fiber (1.7g/100g) supports satiety and digestive health while maintaining insulin stability. The presence of lutein and beta-carotene (indicated by vitamin A content) supports ocular health—a key longevity marker. Celtuce's low sodium profile makes it ideal for blood pressure management, while its manganese content (0.688mg/100g) contributes to bone health and antioxidant defense.
Potassium regulates vascular tone and sodium balance while folate reduces homocysteine, an independent cardiovascular risk factor
High water content (95%) combined with dietary fiber promotes fullness signals while maintaining extremely low caloric density
Beta-carotene and lutein accumulate in the retina and macula, protecting against age-related macular degeneration
Lactucin and related compounds modulate inflammatory pathways and may reduce systemic inflammation markers
Folate serves as methyl donor in one-carbon metabolism, supporting epigenetic regulation and genomic stability
Celtuce works optimally in lunch meals when paired with protein and healthy fats, supporting satiety through afternoon and aiding folate-dependent processes during peak metabolic hours
Breaks a fast
While extremely low-calorie celtuce could technically fit fasting protocols, its benefits are maximized with fat for carotenoid absorption and protein for amino acid utilization

Celtuce is classified as a vegetable. Celtuce is a leafy Asian vegetable combining lettuce and celery characteristics, providing low-calorie nutrition rich in potassium, vitamin A, and folate for cellular health.
Celtuce scores 92/100 in Formulate, making it an exceptional choice. Its strongest contributions come from Manganese, Vitamin C, Folate. The score blends nutrient density, fiber, healthy fats, protein quality, bioactive compounds, and glycemic impact.
Not particularly. A 85 g serving provides about 0.7 g of protein (~1% of the 50 g daily value).
Not really. A 85 g serving provides about 1.4 g of fiber (~5% of the 28 g daily value).
In a 85 g serving, celtuce is highest in Manganese (~25% DV), Vitamin C (~18% DV).
Yes — it fits comfortably in most keto plans. A 85 g serving has about 1.7 g of net carbs (3.1 g total minus 1.4 g fiber).
Best in the midday. Celtuce works optimally in lunch meals when paired with protein and healthy fats, supporting satiety through afternoon and aiding folate-dependent processes during peak metabolic hours
A typical serving is around 85 g (~15 kcal), based on the FDA's Reference Amount Customarily Consumed for this food category. There's no fixed daily target — most adults benefit from rotating celtuce alongside several other vegetable sources.
Celtuce pairs nicely with: Pair with olive oil because fat-soluble carotenoids (vitamin A) require dietary lipids for optimal absorption; Combine with B12-rich foods (fish, eggs, fortified plant foods) since folate and B12 work synergistically in one-carbon metabolism; Mix with sulfur-containing vegetables (garlic, onions, cruciferous greens) for additive anti-inflammatory and antioxidant effects; Serve with vitamin C sources (citrus, tomatoes, peppers) to enhance iron bioavailability and support antioxidant recycling.
