In-Depth Information
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 abbrevi-
ations for measures such as teaspoons, cups, and tablespoons, and uses numerical digits for quanti-
ties (e.g., 1 egg, 2 cups) rather than spelling them out (one egg, two cups). Some common
substitutions are shown in Fig. 14.27. Your program should display a warning such as, “Always con-
sult your physician before making significant changes to your diet.”
Your program should take into consideration that replacements are not always one-for-one.
For example, if a cake recipe calls for three eggs, it might reasonably use six egg whites instead.

Your program should consider the user's health concerns, such as high cholesterol, high blood pres-
sure, weight loss, gluten allergy, and so on. For high cholesterol, the program should suggest substi-
tutes for eggs and dairy products; if the user wishes to lose weight, low-calorie substitutes for
ingredients such as sugar should be suggested.

Spam (or junk e-mail) costs U.S. organizations billions of dollars a year in
