Introduction
Have you ever seen an apple pierced with several nails and wondered why? This old tradition might look strange, but it was historically used to increase iron intake naturally. Before modern supplements, people in various cultures relied on this simple method to help fight iron deficiency. But does it really work, and is it safe? Let’s explore the history, science, and safety of this practice.
Why Did People Put Nails in Apples?
Iron deficiency was common, especially where meat was scarce or expensive. People discovered that inserting iron nails into acidic fruits like apples triggered a chemical reaction: the fruit’s natural acids release small amounts of iron from the metal. Eating the apple provided an early, homemade iron supplement.
This method was used to help prevent or treat anemia, a condition caused by low iron levels that can lead to fatigue, weakness, and pale skin.
