Abstract
Some of the main traits of urbanization are transition in macronutrient consumption and change in eating habits. Driven by cash economy, marketing, and other socio-cultural factors, urban dwellers have shifted toward the consumption of fast and processed food rich in fat and sugar. This transition in diet has affected health adversely aggravating many chronic illnesses such as diabetes, hypertension, gastro-esophageal reflux disease, and others. Gastro-esophageal reflux disease (laryngopharyngeal reflux disease) is a known and common culprit in patients with voice problems. High fat diet and the intake of refluxogenic products cause dysfunction of the lower and upper esophageal sphincters. As a result, there is back flow of gastro-duodenal contents into the larynx and pharynx leading to a constellation of symptoms including hoarseness. The transition in diet also has been linked to body weight. Obesity is known to impact voice by impairing respiration and increasing intra-abdominal pressure. It also causes marked alteration in vocal tract configuration and anatomy. This chapter reviews the impact of urbanization-induced transition in diet on voice. The pathophysiology of dysphonia in the context of macronutrient consumption and eating habits is emphasized.
