Blackberries’ health benefits are incredibly versatile. Like many other berries, the fruit is rich in vitamin C as well as antioxidants known as bioflavonoids.
Beyond that, eating blackberries can aid with digestion and staying alert, and tightens tissue, leading to younger-looking skin. There are around 62 calories in a single serving of the berries.
Most types of lettuce — whether it’s romaine or iceberg — only have about 10 to 2o calories per serving. And although lettuce won’t add a lot of protein to your diet, it will add plenty of vitamins and nutrients like folate, iron, and vitamins A and C.
