The ancient Maya ate a mostly plant-based diet built around maize (corn), beans, squash, and chili peppers, with extras like fruits, cacao drinks, and some meat and fish when available.

Core staples: “Three Sisters”

  • Maize (corn) was the main food, eaten daily as tortillas, tamales, porridges, and thick drinks like atole and pozole.
  • Beans climbed the corn stalks and, together with maize, provided a complete protein.
  • Squash (flesh and seeds) added calories, oils, and vitamins and grew at the base of the corn plants.
  • Chili peppers were used constantly to add flavor and spice to stews, sauces, and drinks.

Other plants and flavors

  • Common fruits: avocado, guava, papaya, pineapple, soursop, and various wild fruits.
  • Vegetables and roots: sweet potatoes, cassava (yuca), jicama, tomatoes, and tomatillos for sauces and stews.
  • Seasonings and extras: vanilla, wild onions, herbs, and salt where it was accessible.

Meat, fish, and animal products

  • Domesticated animals: turkey was the main domestic meat; dogs were also eaten in some contexts.
  • Hunted game: deer, peccary (wild pig), armadillo, iguana, monkeys, and wild birds when available.
  • Fish and seafood: fish, shellfish, turtles, and manatees in riverine and coastal areas.
  • Eggs and occasional honey from native stingless bees added extra protein and sweetness.

Cacao and special drinks

  • Cacao (chocolate) was usually drunk, not eaten as a bar, often mixed with water, chili, maize, or spices and reserved for elites or rituals.
  • Maize drinks: atole (thick hot corn drink) and pozole (corn soup, often with turkey broth) flavored with chili, cacao, and herbs.

How they prepared food

  • Corn was processed with alkali (nixtamalization) to release niacin and improve nutrition, then ground for masa dough.
  • Cooking methods included boiling stews, grilling and roasting meat, steaming tamales in leaves, and stone-griddle baking for tortillas.
