The prices of winter vegetables in South Korea have increased significantly due to cold weather, decreased sunlight, and increased heating costs. The retail price of zucchini has risen by 52% compared to last year, and the prices of other vegetables such as crickets, water parsley, carrots, and onions have also increased. The growing area of farmhouses has decreased due to labor shortages, leading to an unstable supply and demand. As a result, restaurants are using frozen vegetables or replacing them with less expensive ingredients. The food service industry is being hit hard by these price increases.
