Health Benefits of Periwinkles
If you love snails and other shellfish, you’ll definitely want to give periwinkles a try. These small sea snails are gaining popularity among foodies, not just for their unique taste but also for their various health benefits.
Here are some of the health benefits that periwinkles can offer:
- High in protein: Periwinkles contain approximately 15% protein, making them an excellent source of this vital macronutrient. Protein plays many roles in the body, supporting muscle growth, maintaining bone health, and repairing tissues.
