It includes rice or noodles, soup, vegetables, fish or meat, and pickles. The Japanese diet is rich in antioxidants that help prevent chronic diseases such as heart disease, cancer, and diabetes. Green tea is an essential part of the Japanese diet and is known for its numerous health benefits. Japanese cuisine emphasizes seasonal eating and food presentation.
