Chaya — the Mayan 'spinach tree,' a perennial leafy green of extraordinary nutrient density. Must be cooked before eating because the raw leaf is cyanogenic. A hardy Gulf-South superfood green.
Chaya thrives in Florida and Texas yards with almost no care, giving Gulf-South Black households a perennial, drought-tough, free green that produces through the heat when collards and spinach fail.
Cooked chaya is one of the most nutrient-dense leafy greens known — markedly higher in protein, iron, calcium, and vitamin C than spinach. The iron and calcium directly address two deficiencies common in Black American diets, the dietary nitrate and potassium support nitric-oxide blood pressure lowering, and traditional use as a green eaten with meals aligns with research on its blood-sugar-steadying fiber and polyphenols for T2D. As a hardy perennial it offers year-round greens in the hot Gulf South where tender greens struggle.
CRITICAL: chaya must be boiled or thoroughly cooked for at least 15-20 minutes before eating to break down cyanogenic glycosides; never eat it raw and never cook it in an aluminum pot (it can produce a toxic reaction with aluminum). Wear gloves harvesting some varieties — the leaf can have stinging hairs. After proper cooking it is completely safe.
