Flat leaf or curly leaf….

Parsley is known as a common garnish that is frequently displayed to “dress-up” a dinner plate.
However, many are unaware that this garnish is actually a nutrient-dense garden herb, cultivated worldwide, and which is loaded with vitamins and antioxidants.
Low-calorie parsley is rich in vitamins A, C and K along with powerful nutrients and antioxidants, which may help prevent cell damage, improve bone health, protect eye health, and may also lower the risk of certain diseases.
You may incorporate dried or fresh parsley leaves easily into your diet by adding them to soups, salads, marinades, and sauces.
