The Nutritional Value Checker is an interactive and educational tool designed to help users calculate and understand the nutritional content of their meals. By entering food items or selecting them from a predefined list, users can get detailed information about calories, macronutrients (carbs, proteins, fats), and other key nutritional values. This tool is perfect for health-conscious individuals, parents planning meals for their families, or educators teaching nutrition.

Key Features:

1. Food Database: A predefined list of common foods with their nutritional values. Users can also input custom foods.
2. Dynamic Calculations: Automatically calculates total calories, carbs, proteins, and fats based on selected foods.
3. PDF Download Button: Save the nutritional breakdown as a downloadable PDF for offline reference.
4. Colorful Design: A vibrant and modern layout with clear visuals to make the tool engaging and easy to use.
5. Self-Contained Container: The tool stays within its own container without interfering with the page header or footer.

Use Cases:

• Health enthusiasts can track their daily nutrient intake.
• Parents can ensure their family meals are balanced and nutritious.
• Teachers can use it as part of a nutrition lesson to educate students about healthy eating habits.

How It Works:
Users select food items from a predefined list or manually enter custom foods along with their nutritional values. The tool dynamically calculates the total nutritional content of the selected foods and displays the results in an easy-to-read format. A fully functional PDF download button allows users to save the nutritional breakdown for future reference.
