Struggling to fall asleep or wake up groggy? Registered dietitian Erin Palinski-Wade points to specific foods that can quietly improve nighttime rest — and warns about a single, widespread substance that commonly sabotages sleep when consumed too late. Small changes at dinner and in the hours before bed can make measurable differences to sleep quality tonight and over the long term.
Sleep is shaped by more than mattress comfort: what and when you eat matter. Nutrition influences hormones, brain chemistry and overnight recovery, so adjusting your evening intake can be one of the easiest, evidence-based steps toward steadier sleep patterns.

Foods that can help you sleep
Palinski-Wade highlights options that supply nutrients tied to sleep regulation — not miracle cures, but practical additions that can help your body prepare for rest.
| Food | Why it may help | How to add it to your evening |
|---|---|---|
| Cherries or tart cherry juice | Natural source of melatonin, the hormone that helps regulate sleep–wake cycles. | Small glass of tart cherry juice or a handful of cherries 60–90 minutes before bed. |
| Kiwi | Contains antioxidants and serotonin precursors linked in studies to better sleep onset and duration. | Eat one medium kiwi after dinner or as an evening snack. |
| Almonds and walnuts | Provide magnesium and healthy fats; some nuts also contain small amounts of melatonin. | A tablespoon of chopped nuts on yogurt or with a piece of fruit. |
| Fatty fish (salmon, mackerel) | Omega‑3s and vitamin D may support sleep quality and circadian regulation. | Include a modest portion at dinner a few times per week. |
| Turkey or lean poultry | Source of tryptophan, an amino acid involved in serotonin and melatonin production. | A smaller portion paired with a whole-grain side to avoid heavy meals that disrupt sleep. |
For quick reference, the simplest approach: include a small protein + whole grain or fruit at dinner, and favour foods with magnesium, tryptophan or natural melatonin. These choices support the biochemical pathways that help you fall and stay asleep.
The one substance that often undermines sleep: caffeine
Palinski-Wade singles out caffeine as the most common dietary culprit that reduces sleep quality. It can delay the timing of your body’s internal clock and decrease deep sleep, even when consumed many hours before bedtime.
How to manage it: limit coffee, tea, cola and many energy drinks in the afternoon and evening. Because caffeine’s effects vary by person, a general guideline is to avoid caffeinated beverages within six to eight hours of your planned bedtime — less for people who are particularly sensitive.
- Timing matters: A morning cup is fine for most; afternoon or evening cups are the biggest risk to sleep.
- Hidden sources: Some pain relievers, chocolate and pre-workout supplements contain caffeine.
- Alternatives: Try decaffeinated coffee, warm milk, or herbal teas like chamomile if you want a soothing drink at night.
Practical tips that tie diet to better sleep
Small habits matter more than large, abrupt changes. Palinski-Wade recommends these pragmatic steps that readers can test immediately:
– Keep evening meals modest — heavy, high-fat dinners can delay digestion and interfere with sleep.
– Aim to finish large meals at least two to three hours before bed.
– Balance carbohydrates and protein to avoid blood sugar dips that wake you in the night.
– Limit alcohol close to bedtime; while it can hasten sleep onset, it fragments sleep and lowers overnight restorative phases.
What to watch for
Dietary tweaks help many people but won’t replace medical care for chronic insomnia or sleep disorders. If poor sleep persists despite lifestyle adjustments, consult a healthcare provider. Also be mindful of individual differences: allergies, medications or medical conditions can change which foods are appropriate.
In short, incorporating a few targeted foods and cutting late-day caffeine are low-risk strategies that may improve how you sleep — and how you feel the next day. For persistent problems, however, a tailored plan with a clinician or registered dietitian, like Palinski-Wade, remains the best route.
