Lettuce (Water content: 96%)

Lettuce offers a number of health-beneficial properties. In addition to 1 gram of fiber, one cup (72 grams) of lettuce contains more than a quarter cup (59 ml) of water. It also provides 5% of your daily folate requirements.

Folate is important for pregnant women since it helps to avoid neural tube defects. Furthermore, lettuce is high in vitamins K and A, both of which have been studied for their roles in maintaining the health of your bones and immune system. Furthermore, lettuce's combination of water and fiber makes it particularly filling for low-calorie food. A 1-cup (72-gram) serving has just 10 calories. Salads are a simple way to incorporate lettuce into your diet.
