Thick, succulent stems and oval leaves. Eaten raw in salads or cooked like spinach. Single 100g serving provides 400mg omega-3 ALA (highest of any leafy green), significant magnesium, potassium, vitamin A, and vitamin C. Also contains melatonin at notable levels — one of the few food sources of melatonin beyond tart cherry.
Free from unsprayed gardens and fields — the most affordable food in the database. Sold at farmers markets in summer. Some health food stores. Seeds for home growing are cheap and easy.
The omega-3 ALA content makes purslane unique among vegetables. For the Black community with historically lower access to quality fatty fish (the primary omega-3 source), purslane represents an ancestral plant-based omega-3 source that was literally growing for free in the yard. ALA converts in the body to EPA and DHA at a limited rate (10-15%), but the anti-inflammatory baseline benefit of dietary ALA is documented. The melatonin content is clinically relevant: purslane has some of the highest melatonin concentrations of any vegetable (1.5-4.4mg/100g in some studies — comparable to supplemental melatonin doses). Given the Black sleep gap and the documented relationship between melatonin and melanin production pathways, purslane as a daily food may support sleep architecture. The magnesium content compounds this — magnesium deficiency is the primary nutritional driver of insomnia.
Raw: in salads, adds a mild, slightly lemony, slightly sour crunch. Cooked: sauté 2-3 min with garlic and olive oil (wilts like spinach). Add to soups and stews. Blend raw into smoothies. Available fresh in farmers markets or forageable (from unsprayed areas). Seeds can be grown in a pot on a windowsill — very easy.
