🧄🧅 The Hidden Health Benefits of Garlic and Onion Peels: Why You Should Never Throw Them Away
When cooking, most people instinctively toss garlic and onion peels in the trash or compost bin without a second thought. But what if those papery layers you’re discarding actually hold a treasure trove of health benefits?
Surprisingly, garlic and onion peels are rich in nutrients, antioxidants, and medicinal compounds that can be used in your kitchen and home wellness routine. Let’s explore why you might want to save those skins next time you cook.
🧅 What’s in the Peels?
Both garlic and onion peels are loaded with antioxidants — even more than the bulbs themselves. These include:
- Quercetin: A powerful anti-inflammatory and antihistamine compound
- Phenolic compounds: Known for fighting oxidative stress and inflammation
- Flavonoids: Which help protect the heart, support the immune system, and fight free radicals
- Fiber: Particularly in onion peels, which can benefit digestion
🔍 Top Health Benefits of Garlic and Onion Peels
✅ 1. Boosts Heart Health
The flavonoids and antioxidants in onion skins, especially quercetin, have been shown to help reduce blood pressure, lower LDL (bad) cholesterol, and improve circulation.
✅ 2. Supports Immune Function
Garlic skins contain allicin precursors and sulfur compounds, which may help strengthen your immune system and fight infections — much like garlic itself.
✅ 3. Anti-Inflammatory Power
Onion peels are known to help combat inflammation, which is at the root of many chronic diseases including arthritis and diabetes.
✅ 4. Improves Digestive Health
The peels are a rich source of insoluble fiber, which can help promote a healthy gut and regulate bowel movements.
✅ 5. May Support Skin and Hair Health
The antioxidants in the skins can help promote collagen production, reduce skin aging, and even be used in DIY rinses for stronger, shinier hair.
