What should you eat to optimize your sleep?

Good sleep is inseparable from good health. In fact, lack of sleep can increase the risks of cardiovascular disease, weight gain, diabetes, or even depression.

Our diet directly influences the quality of our sleep. As such, maintaining an appropriate diet throughout the day helps us to benefit from a good night’s rest.

Alongside nutritionist Anthony Berthou, we explain in this article which types of nutrition to choose in order to optimize your sleep.

Our bodies follow 24-hour rhythms

Almost all of our body’s biological functions are regulated by 24-hour cycles: that’s what we call our circadian rhythm. Our internal clock acts as the conductor that will regulate different function’s circadian rhythms. In this way, it will control the production of the sleep hormone (melatonin) at the end of the day and the awake hormone (dopamine) in the morning, helps lower our body temperature and heart rate at night, and even manage memory consolidation during our sleep.

An important element will help our biological clocks to synchronize with a 24-hour rhythm: light. You see, the retina will capture variations in light, which will effectively tell our brains to secrete the appropriate daytime or nighttime hormones, making us awake or sleepy.

The sleep cycle

Our sleep is made up of a series of approximately 90-minute cycles, ranging from 4 to 6 cycles per night. Each cycle is comprised of different phases:

  • Light sleep, which lasts about 20 minutes
  • Deep sleep, which is very restorative
  • REM (rapid eye movement) sleep, which is the period in which we dream

In order to optimize your sleep, it is important for the moment we fall asleep to align as closely as possible to the moment when we naturally begin our first cycle. Conversely, when there is more time that passes between falling asleep and the beginning of the first cycle, you may feel your sleep wasn’t restorative.

To identify the beginning of our sleep cycle, the body sends us different signals: yawns, irritated eyes, drowsiness, concentration problems… So, it is essential to go to bed at the first indications of fatigue in order to not miss the “sleep train.”

Which food for which meal?

Neurotransmitters are vital to our circadian rhythm regulation:

  • In the morning, we need dopamine and norepinephrine, which are going to be our basis for waking up and getting motivated.
  • At night, we need serotonin and melatonin, which are responsible for calming down and regulating sleep.

That’s why it is necessary to prioritize a diet that boosts the production of these neurotransmitters at the right times of day.

1) Breakfast

For breakfast, it is recommended to consume a source of animal protein. These will promote dopamine production, which will stimulate us waking up and feeling motivated. Besides boosting our motivation and alertness, this dopamine production will maximize our circadian rhythm regulation. So, we are getting ready for bed as soon as we eat breakfast!

You can, for example, opt for:

1 or 2 eggs

or 1 yogurt (goat or sheep’s milk)

or 1 ounce of cheese

or 1 piece of high quality ham

There are also plant-based alternatives, especially nuts (almonds, walnuts, cashews, etc.). Chia seeds are another vegetarian alternative, even though they contain less protein per portion.

👉 Check out our article on the ideal breakfast

2) Lunch

At mid-day, it is also recommended to have some protein – animal or plant – in order have enough energy to last until the end of the day. For example, you can go for:

4.2 oz of fish or poultry

or 2 eggs

or 4.2 oz of tofu

or 5.3 oz of cooked legumes (lentils, beans, chickpeas, etc.) even if they are not the ideal option because of their carbohydrate content

These proteins should be paired with fiber-rich legumes will help you feel full and whose low glycemic index will allow for a steady release of energy in the body.

👉 Check out our article on the ideal lunch

3) Snack

For a snack, you can choose a fruit or two pieces of dark chocolate. They will serve as your carbohydrate intake: via insulin secretion, these carbohydrates will promote the production of serotonin, the neurotransmitter which is responsible for relaxation and wellbeing.

Pair this carb intake with a small handful of fatty acids (ideally walnuts and almonds), which will provide tryptophan, an amino acid from which serotonin will be synthesized.

👉 Check out our article on the ideal snack

4) Dinner

In the evening, choose a vegetarian meal without meat, fish, or eggs! In fact, tyrosine – present mostly in animal proteins – promotes dopamine production, a neurotransmitter fuels our experience of waking up and being motivated. If dopamine is ideal in the morning for getting ready, then at night our body needs to produce serotonin, a neurotransmitter responsible for calming down and regulating sleep. This serotonin is synthesized by tryptophan, an amino acid that we find in plant-based proteins: legumes, soy, wholegrain rice, sunflower seeds, chocolate…

Additionally, animal proteins contain amino acids which compete with tryptophan. These amino acids will slow down the tryptophan’s path to the brain; as such, it is not absorbed as well, which affects serotonin production, and therefore, sleep.

Lastly, animal proteins (and cooked fats in particular) put too much stress on our bodies in the evening because their digestion time is longer. The body is going to have to produce more energy, and therefore more heat, to allow this digestion. However, our bodies need to lower their temperature at night in order to sleep.

So, instead, opt for a portion of vegetable protein, as well as for foods which promote serotonin production:

Walnuts and almonds

Yogurts and cheese

Carbohydrates (whole grains or fruits)

👉 Check out our article on the ideal dinner

Sleep disruptors

Several factors can interfere with sleep and prevent restorative rest.

Dietary disruptors:

1) Coffee


Due to its caffeine quantity, coffee stimulates the nervous system for 6 hours after its consumption. To a lesser extent, tea also helps to stimulate our brains.

2) Alcohol


Even though it leads to drowsiness, alcohol also creates a release of adrenaline throughout the night and lowers melatonin levels.

3) Excess animal protein at dinner


As we’ve seen, it is better to go for vegetable proteins at night, which contain carbohydrates and tryptophan which will allow for serotonin synthesis.

4) Cabbage and fermented foods


Cabbage and fermented foods like sauerkraut can lead to bloating and therefore reduce the quality of your sleep.

5) Spices


Spices – like pepper, paprika, or chili –should be avoided at night for people with gastrointestinal sensitivities.

6) Fried fatty foods


Cooked fats – especially those that are fried – increase digestion time and can therefore disrupt sleep.

Optimize your magnesium intake!

Magnesium deficiencies are common. These deficiencies can present themselves through different ways which can disrupt sleep: sensitivity to stress, irritability, anxiety, nervousness, night cramps…

Foods with the richest magnesium content are the following:

  • Dark chocolate (min. 70% cocoa)
  • Nuts (walnuts, almonds, cashews, peanuts, hazelnuts…)
  • Legumes (lentils, chickpeas, white beans…)
  • Whole grains (buckwheat, oats, rye, brown rice…)
  • Sardines in oil
  • Seafood
  • Spinach
  • Figs

Other disruptors:

1) Stress and anxiety


Stress and anxiety affect the quality of our sleep: they create difficulties falling asleep and can lead to insomnia. Mindfulness meditation and even self-hypnosis are practices that can help to reduce stress levels before going to bed.

2) Blue light


The use of screens (computer, tv, phone) at night should be eliminated. These screens produce a blue light which activates up to 100 times more photoreceptors than white light does. As a result, they disrupt our natural circadian rhythm and reduce our sleep time. So, avoid screens as much as possible before going to sleep. The French Agency for Food, Environmental and Occupational Health & Safety (ANSES) recommends limiting the use of LED devices, which are richest in blue light. It is also necessary to fall asleep in a dark environment in order to promote melatonin secretion.

3) Heat


At night, our bodies need to lower their temperature in order to have quality sleep. So, avoid hot baths and showers before going to bed and remember to cool down your room at night to an ideal 62.5°F.

With all of these tips, wishing you good night’s sleep  🌙

    To Heidi’s comment about why having hot baths IS good before bed, sort of half agree with you but I was told ‘ Yes do have warm baths but at least an hour before bed to relax and then the body cools down in response, prepares us to sleep well but if you have it immediately before bedtime this natural response does not happen and we are over-stimulated which is not good for sleep’ so I get where Julia is coming from

        Who would want a hot bath nowadays? It’s not healthy, it’s a waste of water and as far as I’m concerned it’s a waste of time. I absolutely spend a maximum of four minutes in the shower with the water running hot for half the time, finishing off with a minute of cold water.

    Great article, it’s a shame it is promoting animal protein. We should all be focusing more on wholesome plant based foods for our own health and for our planet! Meat and animal products have been linked to many of the leading health problems, including increased risk of cancer (processed meat products are classed as carcinogen by the WHO) and cardiovascular diseases. People need to do their own research and they will soon find that going wholefood plant based is the best you can do for your own health.

      Thats your opinion and you are entitled to it but try not to try and insist people follow it. There had been a massive shift in the last few years . It is also possible to buy very good quality animal products that do not contain any nasty chemicals that impact on our health. Many so called healthy plant based products also contain disruptive chemicals

        Thank you for pointing this out, Deb and you are absolutely right, plant based foods can be incredibly unhealthy. However, vegetarianism and veganism isn’t always just about healthy eating. A lot of people choose plant based diets for ethical reasons so for those animal protein of any kind is really not an option.

      3. David

        I agree; who would eat Quorn the most processed food source ever! The thought of it makes me feel ill! I like eating natural food whatever it’s source and in any case reading the article it does suggest not eating animal based foods as your evening meal…

    Directionally sound but oversimplified. No animal protein at night? This is a bit too categorical. Very heavy red meat dinners can impair sleep in some, but light, lean protein (fish, eggs, even chicken) often improves satiety and stabilises blood sugar overnight. The idea that animal protein “blocks” tryptophan is based on small mechanistic studies, not real-life meals. The dopamine/serotonin narrative is neat, but our brain chemistry isn’t that linear. Sleep quality depends as much on meal timing, blood sugar balance, and gut comfort as it does on specific neurotransmitter precursors. What actually works best for sleep (from strongest evidence):

    Don’t go to bed hungry → a small snack (protein + carb, e.g. yogurt with berries, oatcake with nut butter) can prevent 3am wake-ups.

    Avoid huge, late dinners → especially very fatty or spicy ones.

    Prioritise low-GI carbs in the evening → lentils, beans, sweet potato, whole grains — they help serotonin conversion and calm blood sugar swings.

    Magnesium-rich foods → leafy greens, seeds, nuts, cacao can promote relaxation.

    Consistent timing → your body craves routine even more than perfect food combos.

    I’m surprised and disappointed to see you advising people that they ‘must’ consume animals. It’s no secret that we can get everything we need from plant sources, and it’s essential that we shift to a plant-based food system.

    We have no need and no right to enslave and exploit other sentient beings, for food or anything else.

    Even if it wasn’t morally and ethically repugnant to do this to others, animal agriculture is the leading cause of species extinction, ocean dead zones, water pollution, habitat destruction, deforestation & human-wildlife conflict, and is one of the leading causes of our climate emergency.

    It’s breathtakingly ignorant and irresponsible to advise people to eat animals. This should be corrected in the original piece.

        Totally agree, was dismayed that outdated view/promotion of eating animal products….
        Healthy plant based diet should be advised..

      I think you’ve misunderstood the article. It doesn’t tell anyone that eating tasty animals is a ‘must’.

        It recommends it, which it shouldn’t.

        That’s your opinion Dylan, and you’re entitled. To it. As a lifetime member of PETA (People Eating Tasty Animals) I disagree.

      Concise, informative article, but completely agree with Dylan. We need to be advising people on the best plant based alternatives to animal protein. (I’m vegetarian for 50 years and in excellent health)

        I think you are being disrespectful to the extreme.

      I think it very important to allow people to make their own decisions . Personal opinions are very important but try to avoid pushing your personal agenda to everyone else as it can appear aggressive and bullying and we have had enough of that agenda and their violent methods . It does not persuade people . The Yuka app has been transformative for many and i personally object to a minority trying to change the agenda. Stick to your lifestyle but allow others to do so as well .

      I agree. It’s disappointing and outdated to be promoting animal protein as part of a healthy diet.
      I love the app but this is disappointing.

      Thank you for sharing your perspective. I respect your views on plant-based living, though I don’t share the conclusion that consuming animal products is either unnecessary or inherently unethical for everyone.

      While it’s true that many people can meet their nutritional needs on a well-planned plant-based diet, it’s also the case that others find animal products to be the most reliable or practical way to meet certain nutritional requirements. There is no single dietary approach that suits all people equally well, and acknowledging this isn’t the same as ignoring sustainability or ethics.

      I also believe it’s important to consider nuance in discussions about food systems. The environmental impact of animal agriculture varies greatly depending on farming practices, geography, and scale. Regenerative, small-scale, and pasture-based systems, for example, can support biodiversity and soil health rather than destroy them.

      In short, I don’t agree that advising the inclusion of animal products is “ignorant” or “irresponsible.” I see it instead as recognising human diversity, cultural traditions, and the complexity of nutrition and sustainability.

      It’s only advice, not a direct order and from a nutritional point of view not a moral one. You don’t have to follow the advice if it goes against your principles. However many people will find the article interesting whether they eat animal based products or not.

    This plan has worked for me! I have used prescriptions to fall asleep, woke up after 3 hours, wide awake and starving. I have used herbal supplements, no sleep. We now eat dinner for breakfast Sunday-Friday and I sleep. We do like a sit down “normal” dinner on Saturday night or when at a friends house. I have suffered from insomnia for 50 years and this simple change on when I eat animal or heavy proteins has literally changed my life. No western medical doctor has ever suggested this change. Thank You Thank You Thank You

    When I click on “ideal dinner” option, it links to an article in another language and I speak English.

      If you scroll to the bottom of the article and change the language to EN for English, it is the correct article.

    Am I understanding that it IS good to eat cheese and yogurt in the evening to produce serotonin? Would these be vegetarian products and not dairy?

      A vegan eating chickpeas and brown rice for dinner might line up with sleep science… but if they’re having a tub of processed coconut yogurt dessert, they’re in the same boat as someone else with a late-night kebab! Fake yogurts, fake cheeses, oat/almond milks is often ultra-processed with added sugars, gums, and oils, not exactly sleep-friendly.

        As with the recommendation to eat ham – you need to look around and do some research and you will actually find very healthy vegetarian and vegan foods – and tasty as well.

      My sleep pattern changed within 4 days. I love this plan and will never go back to the previous ways. We do cheat on Saturday night as we can sleep in on Sunday. We cheat if at a friends house, otherwise we stick to the plan.

    NIght temperature at 62.5? I turn our thermostat down to 73 at night, and still need a sheet, a comforter, and two blankets to keep from freezing. Maybe that’s because I live in Texas, and am used to 100° temperatures during the day! ¯\_(ツ)_/¯

      I would have trouble with 62 degrees as well. My lowest would be 67-68.
