According to the National Sleep Foundation, changes in sleep patterns are a part of the aging process. Many people experience difficulty falling asleep and then staying asleep as they age, and that difficulty can make men and women over 50 feel more tired during the day.

But even though difficulty sleeping may be a part of aging, that does not mean men and women over 50 cannot take steps to improve their sleeping patterns. For example, certain snack foods may help to improve quality of sleep, especially when these foods replace less healthy snacking options. While men and women over 50 should always consult with their physicians before making any changes to their diets, the AARP notes that the following are a handful of snack foods that promote better sleep.

• Almonds: Magnesium is a mineral with muscle-relaxing properties, and almonds contain enough magnesium to help men and women get a better night’s sleep. A small amount of almonds before bed might be enough to make falling and staying asleep easier.

• Bananas: Much like almonds, bananas provide a substantial amount of magnesium. Bananas also contain the amino acid tryptophan, which many people associate with Thanksgiving turkey. While tryptophan might be most often associated with the sleepiness people feel after eating a holiday meal, it also has been linked to better sleep quality, so a banana shortly before bed might be just what you need to fall and stay asleep.

• Cheese and crackers: One more traditional snack may just help you get a better night’s sleep. Cheese and crackers contain tryptophan and carbohydrates, which can induce a better night’s sleep and help you fall asleep sooner.

• Cherries: Cherries contain the sleep hormone melatonin, and the AARP notes that recent studies indicated that participants who drank tart cherry juice on a daily basis fell asleep more quickly and slept longer and better than participants who did not.

• Hummus: The primary ingredient in hummus is chickpeas, which are loaded with tryptophan, folate and vitamin B6. Folate has proven especially beneficial to older men and women who need help regulating their sleep patterns, while vitamin B6 helps the body regulate its clock.

• Peanut butter: Peanut butter is another snacking item loaded with tryptophan.

• Walnuts: Like cherries, walnuts contain melatonin, which can contribute to a longer, more restful night’s sleep. Walnuts also can help regulate stress, which is a leading cause of sleeping difficulty.

Many men and women experience difficulty sleeping as they age. But the right foods may just help combat such problems and help men and women get a more adequate night’s sleep.
