Lemon peels are often discarded without a second thought, but they are a powerhouse of nutrients and beneficial compounds. In many ways, the peel is even more beneficial than the lemon juice itself.
Here’s a detailed look at the many benefits of lemon peels, from health to household.
Health and Nutritional Benefits
Lemon peels are packed with essential vitamins, minerals, and fiber.
1. Rich in Nutrients and Antioxidants:
· Vitamin C: A tablespoon of lemon peel provides about 9% of your Daily Value (DV). Vitamin C is crucial for immune function and skin health.
· Fiber: The peel is an excellent source of fiber, which aids digestion, helps regulate blood sugar, and supports gut health.
· Potassium: Important for heart health and fluid balance.
· Calcium: For bone health.
· Potent Plant Compounds: They contain powerful antioxidants like flavonoids (e.g., diosmin, hesperidin) and limonene, which fight oxidative stress and inflammation in the body.
2. Supports Oral Health:
· The peel contains citric acid and antimicrobial compounds that can help combat the bacteria that cause bad breath and cavities. Rubbing a fresh peel on your teeth (rinsing afterward) is a traditional remedy, but be cautious as the acid can also affect enamel.
3. Boosts Immune Function:
· The high concentration of Vitamin C and bioflavonoids in the peel works synergistically to strengthen the immune system and help your body fight off infections.
4. May Promote Heart Health:
· The fiber, potassium, and antioxidants (like hesperidin) in lemon peels can contribute to heart health by helping to lower LDL ("bad") cholesterol, regulate blood pressure, and improve blood vessel function.
5. Possesses Antimicrobial and Antifungal Properties:
· Studies have shown that the extracts from lemon peel have activity against various harmful microorganisms, including E. coli, S. aureus, and certain fungi like Candida.
6. May Aid in Cancer Prevention:
· Some test-tube and animal studies suggest that compounds in lemon peel, like limonene and flavonoids, may have anti-cancer properties. However, more human research is needed in this area.
Practical and Household Uses
Beyond health, lemon peels are incredibly versatile around the home.
1. Natural Cleaner and Deodorizer:
· All-Purpose Cleaner: Soak lemon peels in a jar of white vinegar for a few weeks. Strain the liquid, dilute with water, and use it to clean countertops, glass, and other surfaces. It cuts through grease and leaves a fresh scent.
· Garbage Disposal Freshener: Toss a few frozen lemon peels into your garbage disposal and run it with cold water. It will clean the blades and eliminate foul odors.
· Room Freshener: Simmer lemon peels in a pot of water with herbs like rosemary or mint for a natural, chemical-free air freshener.
2. Culinary Uses (The Zest is Best!):
· Flavor Booster: Use a microplane or zester to add fresh lemon zest to salad dressings, marinades, baked goods, pasta, seafood, and cocktails. The zest contains the most potent essential oils and flavor.
· Lemon Sugar/Olive Oil: Add strips of peel to a jar of sugar to make lemon sugar for baking, or to a bottle of olive oil for a citrus-infused cooking oil.
· Candied Lemon Peel: A delicious treat that can be eaten on its own or used as a garnish for desserts.
3. Beauty and Personal Care:
· Skin Exfoliant: Mix dried, powdered lemon peel with honey or yogurt to create a gentle, brightening face mask or scrub. The citric acid can help exfoliate dead skin cells.
· DIY Bath Soak: Add a handful of fresh or dried lemon peels to your bath for a refreshing and invigorating soak.
Important Precautions and How to Use
· Wash Thoroughly: Always wash lemons scrubbing the skin under running water to remove dirt, bacteria, and pesticide residues.
· Buy Organic When Possible: If you plan to consume the peel regularly, opting for organic lemons is best to minimize pesticide exposure.
· Moderation is Key: Due to the high citric acid content, consuming large amounts of lemon peel can be harsh on tooth enamel and the digestive system. Start with small amounts, like a teaspoon of zest.
· Not a Substitute for Medical Advice: While beneficial, lemon peels are not a cure-all and should be part of a balanced diet.
How to Prepare and Store
· Zesting: Use a fine grater or a special zesting tool to remove the outer, yellow layer. Avoid the bitter white pith underneath.
· Peeling: Use a vegetable peeler to remove long strips of peel for infusions.
· Drying: Spread the peels on a baking sheet and dry them in a low-temperature oven (around 150°F / 65°C) or in a dehydrator. Once completely dry and brittle, you can store them in an airtight container for months and grind them into a powder as needed.
In summary, don't throw away that lemon peel! It's a fragrant, flavorful, and functional part of the fruit that can boost your health, enhance your cooking, and clean your home.
