Video 5 Chocolate has become really a health food. The idea that chocolate is healthy, is certainly not new British Ad in the 1800s presented the idea that drinking cocoa is healthy. Certain myths/ facts associated with chocolate: •Acne: It is actually not true that chocolate causes acne •Heartburn: It CAN actually cause heartburn in certain people who are susceptible. What happens is that at the base of the esophagus, we have a valve, and this valve prevents the content from the stomach, which is acidic, from coming back from refluxing into the esophagus. For some reason, eating chocolate relaxes this valve and makes it possible for the acidic contents of the stomach to come up in the esophagus. This problem is known as GERD Gastro Esophageal Reflux Disorder •Tooth Decay: It’s the sugar which is often present in chocolate that causes tooth decay. As we learned previously, in the presence of s. mutans that are present in the mouth, sugar gets converted into lactic acid and plaque lactic acid. The lactic acid is what attacks at the enamel of the teeth, and thus eats away at our teeth ( tooth decay). In fact, chocolate contains some antibacterial agent that would fight off the s.mutans •Migraines: Anecdotal evidence that chocolate can induce migraines.

Firstly, because since its high in sugar it tends to smoothen the throat (lessens the irritation of the throat). Also, chocolate contains a chemical known as theobromine. Theobromine is an antitussive; it suppresses the cough signal in the brain. The presence of theobromine is the reason why chocolate can be poisonous for some small animals. The small animals don’t have the ability of actually metabolizing theobromine and this leads to a buildup of this chemical that can be deadly. •- Heart disease: there are some benefits of chocolate. It can help prevent heart disease. Stearic acid, a type of fat present in chocolate is neutral in terms of increasing blood cholesterol levels. As we learned, there are different types of cholesterol.: Good Cholesterol (HDL) and Bad Cholesterol (LDL) and Oxidized LDL Cholesterol (the ugly- even worse than LDL) Chocolate is rich in antioxidants like the flavanols. The flavanols prevent the oxidation of LDL cholesterol into oxidized LDL Cholesterol. The darker the chocolate, the better it is for heart disease. We know that the French have a very low incidence of heart disease. Some people claim that is it associated with the consumption of wine. But there might be another explanation; French drink a lot of coffee, and coffee is the best source of antioxidants. In cafes in France they serve coffee with a small piece of chocolate; so even more antioxidants!
