The "Foods and Meals" page is where you will be able to manage the foods and meals in your personal registry. There are three options to choose from on that page:

The first option is to "Add/Update a Food". Upon selecting this option, you will be prompted to provide information about the food you wish to add. This information includes:
- The name of the food
- The unit of measurement (ounces, grams, cups, or maybe the food itself, like in the case of an egg)
- The serving size (how many of your unit of measurement)
- The number of calories in one serving
- The number of grams of carbs in one serving
- The number of grams of protein in one serving
- The number of grams of fat in one serving

The second option is to "Add a Meal", which requires you to enter the name of the ingredient(s) alongside the serving size of the ingredient(s). Meals can contain any number of ingredients, and you can add more ingredients by clicking the "Add Ingredient" button. Reversely, you can remove the most recently added ingredient by clicking the "Remove Ingredient" button.

The third and final option is to "Remove a Food/Meal", which requires you to enter the name of the food/meal you'd like to remove. After that is entered, your selection will be removed from the registry and you won't have to provide any further information.

The "Today's Nutrition" page is where you will be able to update and view your calories and macros for the current day. There are two options to choose from on that page:

The first option will be to "Add a Food/Meal to Today's Nutrition". Upon selecting this option, you will be prompted to provide the name and the number of servings for the food/meal you wish to log. The program will then increment the total calories, carbs, protein, and fat for the day based on your inputted food/meal's nutrition facts (and number of servings).

The second and final option will be to "Remove a Food/Meal From Today's Nutrition". Upon selecting this option, you will be prompted to provide just the name of the food/meal you would like to remove from the log. The program will then decrement the total calories, carbs, protein, and fat for the day based on your inputted food/meal's nutrition facts (and number of servings that the program detects).
