Poor Oral Health Leads to Social and Emotional Problems A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems. Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection. The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries. "Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too." He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations. "It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation." Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods. But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.

Yes, it's still 2015, but as USA Today says, "it's never too early to plan your 2016 travels". With so many hot destinations around the globe, "where should I go?" can be difficult to answer. According to Lonely Planet, though, Brazil is a fine choice - on April 29, the travel guide named that country the top one to visit in 2016. "As if endless strands of coast and mountains splashed with rainforest didn't already add up to an unfair share of heaven , Brazil held one of the greatest sporting events in the world, the 2014 FIFA World Cup, and the 2016 Summer Olympics, another greatest one, will be followed ," explained Lonely Planet. Brazil is the largest and most populous country in South America. It boasts the Amazon, the world's largest jungle , which is home to a variety of plants and animals. But the great landscape is not the only thing Brazilians take pride in. The colors green and yellow might make most people think of Brazil's soccer team even more than its national flag. Soccer is more than a sport in Brazil; it's a way of life. In fact, the World Cup brings Brazilians together. It is interesting to note that the general elections in Brazil are usually held during the same year as the World Cup. Political parties try to take advantage of the patriotic enthusiasm created by soccer to inspire political energy. Alongside soccer, samba is another emblem of Brazil. The country's most traditional dance is highlighted every February at the Rio Carnival, which is one of the world's biggest. "Brazil has left its second-class nation status ," said former Brazilian president Luiz Inacio Lula da Silva in 2009 after Rio de Janeiro was awarded the 2016 Olympics. Brazil's growing economy, fueled by oil and aircraft factories, has made it more than just a nation of samba, soccer and beaches. These days, it might just be the best tourist destination in the world. The authors purpose in writing the article is to _ . A) explain why Brazil will be holding the two sporting events B) give an introduction of Brazil as a tourist destination C) give an objective review of Brazil as a nation D) prove that Lonely Planets recommendation is right
