While it might sound strange at first, but sticking a nail into an onion is an old-school trick that actually has certain surprising benefits! Your grandmother knew something that most people don’t! Below’s why this hack is worth trying.

1️⃣ Increases Iron Absorption in Food 💪

An iron nail causes a chemical reaction in onions since they are inherently acidic. The acidity enhances the onion and any food you prepare with it by assisting in the release of iron from the nail.

✔ Wonderful for people with iron deficiency (anemia)
✔ Natural way to boost iron levels in food
✔ traditionally used in cooking to fortify meals with iron

💡 How to do it?

– Step 1: Use a clean, rust-free iron nail (boil it in water first to sterilize it).
– Step 2: Insert the nail into a whole onion and leave it for a few hours or overnight.
– Step 3: Remove the nail and use the onion in soups, stews, or sauces.

2️⃣ Natural Pest Repellent 🦟

Additionally, this trick is used in gardens! A nail inside an onion releases sulfuric compounds to repel insects and pests naturally. Put them around your plants to keep bugs away.

3️⃣ Extends Onion Freshness 🌱

Certain people believe that putting a nail in an onion helps slow down sprouting, keeping it fresh longer.

Does This Actually Work? 🤔
