Question

16.26 (Cooking with Healthier Ingredients) Obesity in America is increasing at an alarming rate. Check the map from the Centers for Disease Control and Prevention (CDC) at www.cdc.gov/ nccdphp/dnpa/Obesity/trend/maps/index.htm, which shows obesity trends in the United States over the last 20 years. As obesity increases, so do occurrences of related problems (e.g., heart disease, high blood pressure, high cholesterol, type 2 diabetes). Write a program that helps users choose healthier ingredients when cooking, and helps those allergic to certain foods (e.g., nuts, gluten) find substitutes. The program should read a recipe from a JTextArea and suggest healthier replacements for some of the ingredients. For simplicity, your program should assume the recipe has no abbreviations for measures such as teaspoons, cups, and tablespoons, and uses numerical digits for quantities (e.g., 1 egg, 2 cups) rather than spelling them out (one egg, two cups). Some common substitutions are shown in Fig. 16.27. Your program should display a warning such as,
