Diet

People’s diets vary from one country to another. Diets can also vary within a single country. Geographic differences explain part of this variation. For example, people who live near the ocean might eat greater amounts of fish than people who live farther inland. People living in cool regions with short growing seasons depend on crops that mature quickly, such as potatoes. In warm, wet lowlands where the soil retains water, rice is often a staple.

Geographic factors are less important today than they were a century ago. Improved methods of agriculture and transportation, as well as increased trade and tourism, have made more types of food available to a wider variety of people.

Improved methods of food processing, preservation, storage, and shipping allow many people to enjoy foods produced far from their homes. Spanish olive oil, French cheeses, and sardines from Norway, for example, are eaten as far away as Australia.

Local traditions and customs play a role in determining what foods people eat and how they are prepared. English tradition encourages roast beef and Yorkshire pudding, a type of bread, be eaten together. Many Asians serve rice with almost every meal.

Economic factors also affect what people eat. In the U.S. state of Maine, lobster is usually a relatively inexpensive food. The shellfish is native to the state’s coastal areas and has been a traditional food for hundreds of years. However, lobster is a luxury item in the Midwest, where it must be flown in. Lobster dishes served in Iowa may cost two to three times what they do in Maine.

In developed countries, many people have enough money to buy a variety of nutritious foods. Malnutrition is not a large problem, and people have a long lifespan. But even in these countries, there are many people who cannot buy these foods because resources are not evenly distributed throughout the population. In some places, healthy, nutritious food can be more expensive than so-called “junk food,” which has many calories but little nutritional benefit.

Even those who can afford healthy food may eat poorly. The diets of many people in developed countries are too high in the fats, salt, and refined sugars found in junk food. These diets are too low in fruits, vegetables, and fiber.

In developing countries, malnutrition is more common. A poor harvest, flood, or drought may cause famine, because the community or nation is not economically able to import food.

The diets of the urban and rural populations of developing countries are often quite different. People in urban areas eat more processed foods, while people who live in rural areas may have access to fresh milk, fruits, and vegetables. However, people living in rural areas are the first to be affected by a poor harvest.

Food and Culture

People do not eat only to obtain nutrients and ward off hunger and starvation. People’s eating habits are strongly influenced by culture. Rituals around preparing, sharing, and consuming food serve social roles as well as biological ones.

Religion sometimes plays a role in what, and when, people eat. Followers of the Jain religion, for example, strongly believe in nonviolence toward all living things. Strict Jains never eat meat. Many Jains also refrain from eating potatoes and other tubers because many small organisms are harmed as the tubers are pulled from the earth.

Jewish kashrut law and Muslim dhabihah law outline many rules for eating. Both include a ban on pork. Food that is prepared according to kashrut law is called kosher, while food that is prepared according to dhabihah law is called halal.

During the month of Ramadan, Muslims fast, or avoid eating, during daylight hours. Typically, Muslims will eat one meal before dawn and one after sunset, but nothing at all while the sun is shining. Ramadan is considered a time for inner reflection, devotion to God, and self-control.

Feasting is also an important ritual, both for religious and nonreligious reasons. Most religious fasting periods, such as Ramadan, are followed by holiday feasts. Eid al-Fitr is the Islamic holiday following Ramadan. One of the ways Muslims celebrate Eid is to donate food to the poor.

Nonreligious holidays often include feasts as well. In the United States, people gather to eat turkey, stuffing, cranberry sauce, and pumpkin pie on Thanksgiving. In China, families celebrate the Chinese New Year with foods that symbolize luck and prosperity, such as long noodles, chickens, fish, oysters, dumplings, tangerines, oranges, and sticky rice cakes.

Many people make dietary choices based on ethics—beliefs about what is right and wrong. For instance, some people choose not to eat meat out of concern for the environment. Livestock is one of the leading contributors to carbon emissions, and some people reduce the amount of beef they eat to reduce their “carbon footprint.” Many people avoid eating meat out of concern for animal welfare.

Vegetarians avoid eating all meat and fish. Vegans avoid all animal products, including eggs, milk, cheese, and honey. Some people who are not vegetarians may raise or buy humanely produced animal products such as free-range chicken and grass-fed beef.

Other ethics-based food practices include choosing organic or locally grown foods. People who choose organic foods may do so because of the reduced number of chemicals in the food. Organic food relies little on genetic modification or pesticides. Organic food also releases fewer chemicals into the environment in the form of runoff.

The “locavore” movement values the reduced environmental impact of local foods. There are fewer transportation costs, such as greenhouse gas emissions, with local foods.

The way we serve and eat food is as culturally important as what foods we consume. In East Asian countries, most people use chopsticks to pick up their food. In Europe and the Americas, a variety of utensils serve different purposes. A full, formal place setting can include a salad fork, dinner fork, dessert fork, teaspoon, soup spoon, butter knife, and dinner knife. In other countries, such as India and Ethiopia, many foods are picked up with pieces of flat bread rather than utensils.

Table manners vary widely from culture to culture. Manners include rules about how and where people should sit, when to begin eating, which utensils to use in certain situations and with which hand, and what behaviors might be considered rude.

In East Asian countries, it is considered rude to point at people with your chopsticks, or to rest your chopsticks standing upright in your rice. In Malaysia, eating with your left hand is considered unclean. In Japan, it is acceptable and even encouraged to make slurping noises while eating hot noodles, but not while eating soup. In Russia, it is considered polite to leave a bit of food after eating, but in Brazil, people are expected to eat everything on their plates.

Cuisine

Food and food preparation associated with a specific region are known as that region’s cuisine. Cuisine can be national, such as the fresh fish and noodles associated with Japanese food. Cuisine can also be regional or local. California cuisine, for instance, is known for mixing different types of national cuisines, such as French and Chinese.

A food’s adaptability to a specific region can define that region. Maize, native to North and Central America, is considered one of Mexico’s greatest “national treasures.” An image of Xochipilli, the Aztec god of maize, appears on Mexico's 100-peso bill.

Most cuisines feature staple foods of the region. In the Democratic Republic of Congo, boiled cassava root is a staple food. The large leaves of the cassava and a fiery pepper sauce called pili-pili are often part of a traditional Congolese meal. Fresh-picked bananas, papayas, and pineapples are frequently eaten. Animal proteins from poultry, fish, and crocodiles are also popular foods in the Democratic Republic of Congo.

Climate can also impact the cuisine of a region. Much of Russia faces cold winters, so few crops grow there. Warm soups are a large part of Russian cuisine. Borscht, or beet soup, is probably the most familiar Russian soup. Beets are vegetables that are capable of growing in the cold, hard ground. Grains that grow well in cold climates are also popular in Russian cuisine. Kasha, for example, is cooked grains, such as buckwheat, barley, or semolina. Blini, or buckwheat pancakes, are served with caviar, smoked fish, butter, and sour cream. Pickles, cucumbers, and onions are widely eaten.

Since Japan is surrounded by the ocean, fish is a mainstay of Japanese cuisine. It is prepared in a variety of ways. Sashimi, for example, is raw fish dipped in seasoned soy sauce. Tempura is prawns or slices of fish and vegetables dipped in batter and fried. Most sushi is made from flavored rice covered with slices of raw or cooked fish and vegetables.

Even non-native foods can define a region. Potatoes were introduced to Ireland in the early 17th century, probably by the explorer Sir Walter Raleigh, who brought the tubers home with him after exploring the Americas. Potatoes, especially the “lumper” variety, grow well in cold climates and rocky soil. Within 200 years, the population of Ireland was dependent on lumpers for most of their carbohydrates. A potato disease, or blight, struck Ireland in the mid-19th century, causing the so-called Irish Potato Famine. More than a million Irish people died of malnutrition, and a million more were forced to immigrate.

Often, cuisine reflects a country or region’s history. Pho, for instance, is a Vietnamese noodle soup made with large chunks of meat, vegetables, and spices, such as basil. Vietnam was a French colony from the 19th century to the middle of the 20th century. French colonists brought French cuisine with them, including the stew called pot au feu. Pho is an adaptation of pot au feu, with the most significant addition being rice noodles, which are native to Southeast Asia. “Pho” even sounds like “feu.”

The growing number of immigrants in many cities has broadened people’s tastes in food. Many foods associated with national cuisines are inventions of immigrants. Chicken tikka masala, for example, is one of the most popular “Indian” dishes in the world. Chicken tikka masala was invented by an immigrant Pakistani chef in Glasgow, Scotland.

Often, immigrants will adapt their traditional diet with foods not available in their homeland. Chinese-American food, for instance, often features tomatoes and potatoes, foods that are not native to Asia.

Cuisine varies widely, even within a specific region and a specific food. In the Carolinas region of the United States, for example, there are more than a dozen types of traditional barbecue. In this region, pork is the most familiar barbecued meat, although chicken and beef are also barbecued. Some barbecues feature a mustard-based sauce, while others feature tomato, vinegar, or molasses. Still other traditional barbecues are “dry,” and feature spice-based rubs instead of sauce.
