"오이" is the Korean word for "cucumber," a popular vegetable known for its refreshing taste and crunchy texture. It belongs to the gourd family and is often used in salads, pickles, and various dishes. Cucumbers are low in calories and high in water content, making them a healthy choice for hydration. In addition to being a staple in many cuisines, 오이 is also rich in vitamins and minerals, including vitamin K and potassium. They can be eaten raw or cooked, and are often enjoyed in summer dishes for their cooling properties.
