Misconception: Plastic Containers Are Always Unsafe
Modern BPA-free plastics are safe for occasional use, but not ideal for long-term meal prep. Repeated heating or prolonged exposure increases the risk of chemical leaching.

Glass is heavier and more fragile, making it less ideal for travel or children's lunches. For these situations, lightweight plastic options are better suited.
