Central Americans and Mexicans, Diets of

The diets of peoples in Mexico and Central America (Guatemala, Nicaragua, Honduras, El Salvador, Belize, and Costa Rica) have several commonalities, though within the region great differences in methods of preparation and in local recipes exist. The basis of the traditional diet in this part of the world is corn (maize) and beans, with the addition of meat, animal products, local fruits, and vegetables. As in other parts of the world, the diet of people in this area has expanded to include more processed foods. In many parts of Mexico and Central America, access to a variety of foods remains limited, and undernutrition, particularly among children, is a major problem. Although access to an increased variety of foods can improve the adequacy of both macronutrient and micronutrient status, there is evidence that the use of processed foods is contributing to the rapidly increasing prevalence of obesity and diet-related chronic diseases such as diabetes.

Traditional Dietary Habits

The central staple in the region is maize, which is generally ground and treated with lime and then pressed into flat cakes called tortillas. In Mexico and Guatemala, these are flat and thin, while in other Central American countries tortillas are thicker. In El Salvador, for example, small, thick cakes of maize, filled with meat, cheese, or beans, are called pupusas. Maize is also used in a variety of other preparations, including tacos, tamales, and a thin gruel called atole. The complementary staple in the region is beans (frijoles), most commonly black or pinto beans. Rice is also widely used, particularly in the southernmost countries, such as El Salvador, Honduras, Nicaragua, and Costa Rica. Historically, major changes in the traditional diet occurred during colonial times, when the Spaniards and others introduced the region to wheat bread, dairy products, and sugar. Wheat is commonly consumed in the form of white rolls or sweet rolls, or, in the northern part of Mexico, as a flour-based tortilla. Noodles (fideos), served in soups or mixed with vegetables, have also become popular.

The consumption of meat and animal products, although popular, is often limited due to their cost. Beef, pork, chicken, fish, and eggs are all used. Traditional cheeses are prepared locally throughout the region as queso del pais, a mild, soft, white cheese, and milk is regularly used in café con leche and with cereal gruels.

Commonly Used Fruits and Vegetables

The region is a rich source of a variety of fruits and vegetables. Best known among these are the chile peppers, tomatoes, and tomatillos that are used in the salsas of Mexico. Avocado is also very popular in Mexican and Central American cuisines. Other commonly used vegetables include calabaza (pumpkin), carrots, plantains, onions, locally grown greens, and cacti. Fruits are seasonal but abundant in the rural areas and include guavas, papayas, mangoes, melons, pineapples, bananas, oranges, and limes, as well as less-known local fruits such as nances, mamey, and tunas (prickly pears from cacti). Traditional drinks (frescos, chichas, or liquados) are made with fruit, water, and sugar.

Methods of Cooking

The traditional preparation of maize involves boiling and soaking dried maize in a lime-water solution and then grinding it to form a soft dough called masa. Soaking in lime softens the maize and is an important source of calcium in the diet. The masa is shaped and cooked on a flat metal or clay surface over an open fire. In some areas, lard or margarine, milk, cheese, and/or baking powder may be added to the tortilla during preparation. Beans are generally boiled with seasonings such as onion, garlic, and sometimes tomato or chile peppers. They are served either in a soupy liquid or are "refried" with lard or oil into a drier, and higher fat, preparation.

Meat, poultry, and fish are commonly prepared in local variations of thin soup (caldo or sopa), or thicker soups or stews (cocido) with vegetables. In Mexico and Guatemala, grilled meats are cut into pieces and eaten directly on corn tortillas as tacos.

These are often served with a variety of salsas based on tomato or tomatillo with onion, chile, coriander leaves (cilantro), and other local seasonings. Tamales are made with corn (or corn and rice) dough that is stuffed with chicken and vegetables. The tamales are steamed after being wrapped in banana leaves. Salvadorian pupusas are toasted tortillas filled with cheese, beans, or pork rind eaten with coleslaw and a special hot sauce.
