What to eat before bed, going by HealthLink BC, is not much: a light snack if you're hungry, and no heavy meal close to bedtime. I sell beds, not food, so I'm passing on its sleep advice: no caffeine for at least 4 to 6 hours before bed, and no alcohol late in the evening.
A bedtime snack is a small amount of food eaten in the last hour or two before sleep, sized to take the edge off hunger rather than fill you up. Merit Home Furniture sells beds and what goes on them across four Vancouver Island stores, and I'm a co-owner who works in the Duncan store. Every health point that follows comes from a named source: HealthLink BC, Health Canada, Canada's Food Guide, the alcohol guidance from the CCSA, or a published study. Where a study is small, I give its size.
None of this replaces a doctor. Heartburn that wakes you, or tiredness that gets in the way of your day, is worth raising with one, and HealthLink BC's warning signs are near the end.
What to eat before bed: the HealthLink BC and Canada's Food Guide view
What to eat before bed starts with portion size. HealthLink BC's page on improving sleep says to avoid heavy meals close to bedtime, and that "a light snack may help you sleep". It also says not to go to bed thirsty, but not to drink so much that you're up in the night to use the bathroom. A glass of water within reach covers the first part, and how high a nightstand should sit has a guide of its own. The page doesn't name one right snack, and no Canadian health body I could find does either.
Canada's Food Guide fills in what a snack can be. Its healthy snacks page suggests eating snacks when you feel hungry, "and not just out of routine", in small portions rather than straight from a big container. Its ideas for snacks at home include these:
- whole grain toast with nut butter and banana
- lower fat yogurt topped with frozen berries and walnuts
- lower fat cheese and whole grain crackers with cherry tomatoes
- whole grain cereal with fruit slices and milk, or an unsweetened fortified plant-based beverage
The guide wrote those for any time of day, not for bedtime, though milk and walnuts in them have had sleep studies. Its wider advice holds at night too: plenty of vegetables, fruits, whole grains and protein foods, with water as your drink of choice.
Should I eat before bed if I'm hungry?
Eating before bed when you're hungry is what Canada's Food Guide describes: a snack because you're hungry, kept small. HealthLink BC's light snack line points the same way. The exception is reflux. HealthLink BC's heartburn advice says late-night snacks "aren't a good idea" for people with heartburn. It asks them to wait 2 to 3 hours after eating before lying down. Without heartburn, a small snack and a glass of water sit inside what both sources describe.
What should I eat at 10pm at night?
A 10pm snack depends on when you go to bed. With a bedtime near 11, HealthLink BC's light snack fits, such as something from the Food Guide list above in a small bowl. Someone with heartburn going to bed at 11 would be eating inside that 2 to 3 hour window, so for them the snack belongs earlier in the evening. Coffee, black tea, cola and chocolate at 10pm all land inside the caffeine-free hours HealthLink BC asks for.
Best foods to eat before bed: what nine studies tested, and their limits
Foods for sleep come up in a handful of studies, and most of them are small. The table sets out each one with its size and what it measured. Read every finding as "research suggests", not as settled. Each row is a single study: one tested a branded juice blend, and one was done in rats.
| Food and study | What it found, and the limit |
|---|---|
| Kiwi: Lin and colleagues, Asia Pacific Journal of Clinical Nutrition, 2011 | 24 adults with sleep problems, 22 of them women, ate 2 kiwifruit an hour before bed for 4 weeks. They fell asleep faster and slept longer than before they started. There was no comparison group. |
| Tart cherry juice: Howatson and colleagues, European Journal of Nutrition, 2012 | 20 volunteers took a tart cherry juice concentrate or a placebo for 7 days. Melatonin in their urine rose, and total sleep time and sleep efficiency improved. Healthy adults, one week each. |
| Tart cherry juice: Pigeon and colleagues, Journal of Medicinal Food, 2010 | 15 older adults with insomnia had 2 weeks on a branded juice blend and 2 on a placebo. Time awake in the night dropped against placebo, but time to fall asleep and total sleep didn't. The authors called the effects modest. |
| Milk and dairy: Komada and colleagues, International Journal of Environmental Research and Public Health, 2020 | A review of 14 studies published from 1972 to 2019. The authors concluded that a balanced diet including milk and dairy helps sleep quality, while noting mixed results between the studies. |
| Fatty fish: Hansen and colleagues, Journal of Clinical Sleep Medicine, 2014 | 95 men in a secure forensic hospital in the US ate Atlantic salmon three times a week from September to February, or a meat meal. The fish group reported better daily functioning. One unusual group, all men. |
| Walnuts: Reiter and colleagues, Nutrition, 2005 | Walnuts held about 3.5 ng of melatonin per gram, and rats fed walnuts had more melatonin in their blood. No people were tested. |
| Rice: Yoneyama and colleagues, PLoS One, 2014 | 1,848 Japanese adults filled in diet and sleep questionnaires. The biggest rice eaters were less likely to report poor sleep. A survey shows a link, not a cause. |
| Passionflower tea: Ngan and Conduit, Phytotherapy Research, 2011 | 41 adults aged 18 to 35 drank a cup of passionflower or placebo tea for a week each. They rated their sleep quality higher on passionflower. Short, self-rated, healthy young adults. |
| Chamomile: Adib-Hajbaghery and Mousavi, Complementary Therapies in Medicine, 2017 | 60 people aged 60 or older at a day care centre took chamomile extract capsules or a placebo for 28 days. Sleep quality scored better on chamomile. Capsules, not tea. |
Almonds, turkey, tomatoes and pistachios show up on most bedtime food lists as well. Turkey's reputation rests on tryptophan, an amino acid. I didn't find a sleep trial of any of the four that I could check against its own abstract, so they're left out of the table rather than guessed at. White rice usually comes with a "possibly" on those lists, for the reason in the rice row.
Best fruit to eat before bed: kiwi and tart cherries
Kiwi and tart cherries are the two fruits with human sleep studies behind them. The kiwi results compare the same people with their own sleep before the study, with no group eating something else. Both cherry studies used juice or concentrate, not a bowl of fresh cherries, and the larger one had 20 people. Canada's Food Guide lists oranges, bananas and plums among its grab-and-go snacks, since they come in their own packaging. On those grounds alone, a piece of fruit is a sensible small snack, whatever the sleep studies end up showing.
Caffeine before bed: how much is in coffee, tea, chocolate and energy drinks
Caffeine before bed is the clearest case in this guide. HealthLink BC says caffeine can stimulate the body for 3 to 7 hours, and that even the small amount in decaf can interfere with sleep. Its sleep page asks for none in the 4 to 6 hours before bedtime. A separate HealthLink BC page on sleep problems puts the cut-off at 6 hours.
Health Canada's caffeine page gives the amounts. Its maximum for healthy adults is 400 mg a day, and 300 mg for people who are pregnant, planning a pregnancy or breastfeeding. Children and teens up to 18 get 2.5 mg per kilogram of body weight. The table uses Health Canada's own averages.
| Drink or food, serving | Caffeine |
|---|---|
| Brewed coffee, 237 ml (8 oz) | 135 mg |
| Filter drip coffee, 237 ml | 179 mg |
| Instant coffee, 237 ml | 76 to 106 mg |
| Decaffeinated coffee, 237 ml | 3 mg |
| Black or green tea, brewed, 237 ml | 30 to 50 mg |
| Regular cola, 355 ml (12 oz) | 36 to 46 mg |
| Chocolate cake, 80 g | 36 mg |
| Sweet chocolate candy, 28 g (1 oz) | 19 mg |
| Milk chocolate candy, 28 g | 7 mg |
| Hot cocoa from a mix, 237 ml | 5 mg |
| Caffeinated energy drink, one serving | Up to 180 mg, the legal cap |
Energy drinks aren't on Health Canada's food list. A separate Health Canada page caps caffeine from all sources at 180 mg per serving of a caffeinated energy drink. The label has to say the drink isn't recommended for those under 14, pregnant or breastfeeding women, or people sensitive to caffeine. One serving at 9pm can hold more caffeine than a mug of brewed coffee.
Chocolate is the easy one to forget. A slice of chocolate cake carries about as much caffeine as a can of cola, by Health Canada's figures. For a light sleeper, an after-dinner coffee and a chocolate dessert add up.
Alcohol before bed: what a nightcap does to your sleep
After a drink you may fall asleep with no trouble, but HealthLink BC says alcohol before bed can wake you up later in the night. Its sleep advice is not to drink alcohol late in the evening. Its insomnia page lists alcohol, caffeine and tobacco among the things that can lead to insomnia.
Canada's Guidance on Alcohol and Health, from the Canadian Centre on Substance Use and Addiction (CCSA), replaced the low-risk drinking guidelines issued in 2011. It sets out risk on a weekly scale:
- 0 drinks a week: not drinking has benefits, and the CCSA names better health and better sleep.
- 2 standard drinks or less per week: you're likely to avoid alcohol-related consequences for yourself or others.
- 3 to 6 standard drinks per week: the risk of several cancers, including breast and colon cancer, goes up.
- 7 standard drinks or more per week: the risk of heart disease or stroke rises significantly.
The CCSA also links more than 2 standard drinks on one occasion to a higher risk of harm, injuries included. HealthLink BC's sleep page still prints the older daily limits, so I've gone with the newer CCSA scale. For anyone finding it hard to cut back, the CCSA suggests talking to a physician or healthcare provider.
What foods should you avoid before bed?
With heartburn, the foods to avoid before bed are those HealthLink BC says may make it worse: chocolate, mint, alcohol, pepper, spicy foods, high-fat foods and caffeine drinks. Tea, coffee, cola and energy drinks are its examples. GERD, or gastroesophageal reflux disease, means the valve at the top of the stomach doesn't close tightly enough, so stomach contents move back up. HealthLink BC adds that heartburn is usually worse after eating, and often worse lying down.
The same pages give the timing. HealthLink BC asks people with GERD to eat several small meals rather than a few large ones, and to wait 2 to 3 hours after eating before lying down. Its food list is personal too. If one food makes your symptoms worse, it suggests stopping it for a while to see whether they ease.
Without reflux, the broad version still holds. The HealthLink BC sleep page puts heavy meals near bedtime on its avoid list, beside caffeine and late alcohol. A large curry at 10pm, a rich dessert and a coffee after it are three strikes against the same night.
Raising the head of the bed for night-time heartburn
Raising the head of the bed is the one item on HealthLink BC's GERD list that involves the bed itself. For night-time symptoms, it suggests 15 to 20 centimetres (6 to 8 inches). On a bed frame with legs, blocks or risers under the two head-end legs can do it. An adjustable base lifts the head section of the mattress on a motor instead. Merit lists the Restwell Peak adjustable base for our Duncan and Port Alberni stores at $999.00 to $1,099.00 before applicable taxes. The Restwell Pinnacle base, which adds massage, is listed for the same two stores at $1,499.00 to $1,849.00.
A base is furniture, not treatment, and nobody at Merit can judge your reflux. Whether a raised head suits it is a question for your doctor. How these bases work with mattresses and frames is set out in our guide to adjustable bed bases.
What is the 3:2:1 rule before bed?
The 3:2:1 rule is a rule of thumb passed around online, and the versions vary. The common one counts back from bedtime: no food in the last 3 hours, no work in the last 2, no screens in the last hour. I couldn't find it on any HealthLink BC or Health Canada page. Its food step sits close to HealthLink BC's timing for people with reflux. Its screen step matches HealthLink BC's advice to keep phones and tablets out of the hours before bed.
What's the healthiest thing to eat late at night?
The healthiest late-night food, on Canada's Food Guide terms, is a small portion of something whole and plain. That means fruit, a few nuts, plain yogurt, a slice of whole grain toast or a bowl of whole grain cereal with milk. The guide asks for snacks with little to no added sodium, sugars or saturated fat, and suggests limiting highly processed ones. Late at night, that rules out most of what sits near a till.
Those choices also stay clear of HealthLink BC's heartburn list. Portions matter most with nuts, which are easy to eat by the handful.
Drinks count as well. Water is the Food Guide's drink of choice, and HealthLink BC's only caution is volume, so you aren't up in the night. Herbal tea before bed appears on HealthLink BC's insomnia page as part of a relaxing bedtime routine, beside a warm shower and soothing music. A late workout raises another timing question: how late exercise before bed can run before it costs sleep.
Whether eating late, or sleeping short, changes your weight is a question for another Merit guide that's still being written, and for your doctor or a dietitian.
Eating in bed: what crumbs and spills do to a mattress
Eating in bed is where food becomes a furniture question, and it's the part of this guide I can speak to from the store. HealthLink BC's sleep advice is to keep the bed for sleep and sex, which leaves the snack at the kitchen table. When it does end up in bed, a spilled glass of juice or a mug of tea soaks into the top layers of the mattress. Merit's protector guide quotes four makers, Restwell, the BC mattress maker, among them, whose warranty terms let a stain end a claim. The fine print in mattress and furniture warranties has a guide too.
A waterproof protector is the cheap fix. At Merit, the Health Guard Premium Terry protector is listed for our Duncan store at $49.00 to $79.00 before applicable taxes. It's the lowest-priced protector in the Health Guard bedding line, which also takes in pillows and sheet sets. We don't ship small items like protectors, as our pickup and delivery terms explain. A protector waits at Duncan for free pickup, or rides along with a furniture or mattress delivery. Which protector does which job, with the warranty wording, has its own guide.
Crumbs are the smaller nuisance, since they stay on the sheet and go with the next wash, one reason to keep a spare from the sheet sets we list. A pillow under a knocked-over mug is harder to rescue, and the guide to choosing a pillow for how you sleep covers when one is due for replacing.
When bedtime heartburn or poor sleep is a doctor's question
Food changes are home treatment, and HealthLink BC sets out when home treatment isn't enough. Heartburn can feel like the chest pain of a heart attack. So its GERD page says to call 9-1-1 or other emergency services immediately for heart attack symptoms, which include:
- chest pain or pressure, or a strange feeling in the chest
- sweating, shortness of breath, nausea or vomiting
- pain, pressure or a strange feeling in the back, neck, jaw or upper belly, or in one or both shoulders or arms
- light-headedness or sudden weakness, or a fast or irregular heartbeat
HealthLink BC says to call your doctor now after vomiting blood, or with bloody, black or maroon-coloured stools. Call a doctor if reflux doesn't improve after 2 weeks of home treatment, or comes with choking, trouble swallowing or a lot of weight loss you aren't trying for.
For sleep itself, HealthLink BC's sleep problems page says to talk to a doctor if daytime sleepiness gets in the way of normal things. It also says not to drive or use machinery while drowsy. After several nights of poor sleep, it suggests reviewing your medicines with a doctor or pharmacist. Kiwi or cherry juice isn't a treatment for insomnia. Pigeon's team found the juice's effects were considerably smaller than those of proven insomnia treatments, cognitive behavioural therapy among them.
For help deciding, 8-1-1 is HealthLink BC's free line anywhere in BC, with nurses there any time. The line can also put you through to a registered dietitian, weekdays 9 to 5, or a pharmacist overnight. Callers who are deaf or hard of hearing can use 7-1-1.
