About half of older adults struggle to fall and stay asleep at least a few nights a week, say researchers from Yale School of Medicine. In fact, insomnia is the most common sleep problem among older adults, according to the National Institute of Aging (NIA). A likely culprit: Your eating habits.

When you eat poorly, you’re likely to sleep poorly, says Chris Brantner, a sleep coach at SleepZoo, an online source of sleep-related informatyion. And when you sleep poorly, you’re more likely to eat poorly.

It’s a vicious cycle. An American Journal of Clinical Nutrition study, for example, found that sleep-deprived people are more likely to consume more calories and choose high-fat food, compared with those who sleep well.

Your waistline isn’t the only thing in jeopardy when you’re groggy. Lack of sleep can hamper your memory, increase your risk of falls, and affect your blood pressure, according to the NIA. And you probably know your mood and stress levels are impacted by your pillow time.

Fortunately, you can break the cycle by rethinking your dinner and late-night snacks. Here’s how.

Skip chili, curry, and pizza.

Fiery dishes are great—for lunch, not dinner.

“Spicy foods can cause heartburn, and 80 percent of people who suffer from regular heartburn and acid reflux will experience it at night,” Brantner says.

You may want to bump pizza and other tomato-based dishes over to lunch, too. Tomatoes are acidic and can cause nighttime heartburn, he says.

If heartburn is a regular nighttime occurrence for you, Brantner suggests trying to sleep on your left side. Studies have shown that can ease symptoms, while lying on your right aggravates it.

For acid reflux, Brantner says sleeping elevated may help. So instead of lying flat on your back, prop yourself up. That drops your stomach below your throat, helping keep the acid where it belongs.

Skip the drive-through.

Burgers and other greasy food can be tough on your digestive system, causing heartburn or general discomfort, Brantner says. What’s more, consuming high amounts of saturated fat before bed was associated with less time in deep, restorative sleep, according to a 2016 study in the Journal of Clinical Sleep Medicine. Low fiber was also linked to low-quality sleep.

Grilled, baked or roasted chicken and turkey are better main-dish options. Fiber-rich, protein-packed vegetables like chickpeas and lentils can be another terrific choice. These will help you feel full, limit excess fat, and help you sleep better.

Skip dessert.

Ending the day on a sweet note sounds nice, but that scoop of ice cream or plate of cookies can lead to poor sleep quality, says Alicia Galvin Smith, a nutritionist at Carpathia Collaborative.

Sugary foods cause insulin and blood sugar spikes, she explains. And this can lead to higher levels of the stress hormone cortisol.

“You may have trouble falling asleep, or you’ll wake up during the night,” she adds.

Skip crackers and cereal

“A common bedtime mistake is eating snacks that are primarily processed carbs, like cereal, crackers, or white bread,” Brantner says. Just like sugary desserts, these foods cause insulin and blood sugar levels to spike, resulting in poor sleep. Plus, carbohydrate-rich foods can mess with levels of melatonin, a hormone that promotes sleep.

That doesn’t mean you need to go to bed hungry. A glass of milk or a piece of cheese are two great late-night snacks. “The calcium in dairy promotes melatonin production,” Brantner says.

Smith also suggests having a handful of nuts with shaved coconut or some olives. Both options are low-sugar and contain healthy fats that won’t hamper your slumber.

Skip a nightcap

A glass of wine may relax you, but it’ll also shake you awake a few hours later.

Alcohol promotes sleep, but it’s not natural sleep, Brantner explains. After about four hours, your body metabolizes the alcohol, and the sedative effects wear off. That’s when you experience “the rebound effect,” he says. You wake up energized and may find it difficult to fall back asleep. Plus, you probably need to take a nighttime trip to the bathroom.

This disruption causes you to miss out on REM sleep, which is when your brain processes information, makes memories, and sweeps itself of toxins. A 2017 study in Neurology found people who get less REM are more likely to develop dementia or Alzheimer’s later in life.

Women tend to experience alcohol’s negative effects worse than men. “This could be related to the fact that women’s bodies metabolize alcohol quicker than men’s, so they can reach that second half of disrupted sleep more quickly,” Brantner says. His solution: If you choose to drink, hit happy hour. Stick to one to two drinks, and drink plenty of water. You’ll help your body metabolize the alcohol before bed.
