What can happen if nutrition is poor regarding nail health?

Nails are a reflection of overall health, and proper nutrition plays a crucial role in maintaining their strength and appearance. When nutrition is poor, the body lacks essential vitamins and minerals that are vital for healthy nail growth. This deficiency often results in nails becoming brittle, which means they are more prone to breaking, chipping, and peeling.

Key nutrients that contribute to nail health include protein, biotin, iron, and zinc. A lack of these nutrients can disrupt the metabolism of keratin, the protein that forms the structure of nails, leading to compromised strength. Brittle nails can also indicate underlying health issues, making it important to consider nutrition as a factor in nail care. This is why the correct answer highlights the tendency of nails to become brittle when nutrition is inadequate.
