Well, firstly, they tend to be low-calorie and very nutritious; and secondly, certain ingredients that make a good salad also induce sound sleep. By eating salad for dinner every night, you can minimize digestion discomfort at night, especially if you normally eat dinner very close to bedtime and also don't have any physical activity between dinnertime and bedtime. An after-dinner walk would help you digest a big meal, but if you don't like to walk at night, then have a small meal and make it a salad.

Make the right salad
When making a salad, pick foods that have a soporific effect and can help improve the quality and amount you sleep. The goal is to ensure that you get the essential vitamins and minerals that you need for a good night's sleep and that your pre-sleep food and drink are easy to digest. You can also add fruit to your salad, so you won't crave anything sweet after dinner. You'll feel satisfied, yet light. The right ingredients will mean no burps, no acid reflux, no gas or bloating — in short, no side effects of eating salad at night.

Another upside is, that when you have salad for lunch, you might end up overeating at dinner time, but if you have relatively hearty foods during the day, (for instance, bean and veggie soups with homemade sourdough bread, or rice and beans with steamed broccoli and carrots) and salad for dinner, you can easily digest the foods during the day with all the activity, and also feel energized and focused. If you cook for the family, making salad at night would mean also getting in more veggies for the rest of the family, even if it's only a small bowl for each member. You can always get creative with toppings that will keep even the kids interested.

Many vegetables and some fruits that go into your salad have high water content. They hydrate your body. Salads also retain the goodness of vitamins, minerals and some enzymes that are lost while cooking. Some raw vegetables contain important live enzymes that can help the process of digestion. Some fibrous veggies like broccoli and dark leafy greens can help clean your gut and bowels and flush your system well first thing in the morning.
