Best Foods for Hot Flashes: 7 Options to Consider

Cooked soybeans, edamame, and tofu are foods to consider for hot flashes, with the strongest direct dietary evidence for cooked whole soybeans as part of a plant-based diet.

Food is not a guaranteed treatment, and the evidence does not show that every soy food works equally well. For a separate look at hydration and comfort, see the best drinks for hot flashes.

7 foods to consider for hot flashes

Use the AI symptom analyzer to organize symptoms before a medical visit; it cannot diagnose their cause.

The first three foods contain soy isoflavones, plant compounds that can interact with estrogen receptors. The other foods can fit into a balanced plant-based eating pattern, but none has been shown on its own to reduce hot flashes in the studies below.

1. Cooked whole soybeans

Cooked whole soybeans have the most relevant evidence on this list. Their isoflavones are one possible reason researchers are interested in soy during menopause, although the mechanism behind any improvement in hot flashes is not established.

In a 2023 randomized trial of 84 postmenopausal women, participants assigned a low-fat vegan diet with ½ cup (86 g) of cooked soybeans daily had a greater reduction in moderate-to-severe hot flashes over 12 weeks than those assigned no dietary changes. The diet group reported an 88% reduction, compared with 34% in the control group.

A smaller randomized trial of 38 women also found greater improvement with the combined diet and soybean approach. Both trials tested the whole eating pattern, not soybeans against an otherwise identical diet, so they cannot establish how much of the benefit came from soybeans alone.

To try the studied food and amount, add ½ cup (86 g) of cooked whole soybeans to a grain bowl, salad, or soup. That is the amount used in the trials, not a proven necessary dose or a guarantee that the same result will occur for you.

2. Edamame

Edamame are immature soybeans and contain soy isoflavones. That makes them a practical soy food to consider, but the trials above used cooked whole soybeans as part of a broader diet; they did not separately test edamame for hot flashes.

Use a serving of cooked edamame as a snack or add it to a salad. There is no established edamame dose for hot flashes, so choose an amount that fits your appetite and meals rather than assuming it is equivalent to the trial intervention.

The evidence for edamame specifically is therefore indirect. Its relationship to the studied food makes it reasonable to consider, not a proven substitute with the same effect.

3. Tofu

Tofu is made from soybeans and also provides soy isoflavones. It may be an accessible way to include soy in meals, but processing and portions differ from those of whole soybeans, so the trial results cannot be assigned to tofu itself.

Add a serving of tofu to a stir-fry, salad, or soup, prepared in a way you enjoy. No specific tofu amount has been established for reducing hot flashes.

The evidence for tofu is indirect: the listed randomized trials tested a dietary pattern containing cooked whole soybeans, not tofu alone. A person who chooses tofu instead should not expect a predictable reduction in symptoms.

4. Lentils

Lentils can provide plant protein and fiber in a meal. They can help make a plant-based eating pattern filling, but there is no demonstrated mechanism in the listed trials by which lentils themselves reduce hot flashes.

Use a serving of cooked lentils in a salad, soup, or grain bowl, or replace some meat in a familiar dish with them. An ordinary meal portion is a practical choice; there is no studied lentil dose for hot flashes.

The evidence is for the combined low-fat vegan and soybean intervention, not for lentils as an individual remedy. Include them if you like them, rather than relying on them to relieve symptoms.

5. Oats

Oats provide fiber and can be part of a varied plant-based diet. Fiber is useful for general nutrition, but the trials we found do not show that oats or their fiber directly change hot flashes.

Have a bowl of oatmeal or add oats to a meal that suits your usual routine. There is no established serving or frequency of oats for treating hot flashes.

Oats are a supportive food choice, not an evidence-based hot flash treatment. Their place on this list reflects their usefulness in a balanced eating pattern, not a trial showing that they reduce symptoms.

6. Leafy greens

Leafy greens can add fiber and nutrients to meals without requiring a restrictive diet. They may help make a plant-focused plate more varied, but no direct hot flash benefit from leafy greens was established in the listed studies.

Add a serving of cooked greens to a meal, or use washed leafy greens in a salad. Choose a portion you enjoy; no particular amount has been tested as a hot flash treatment.

The evidence for this food is indirect and limited to its role in an overall eating pattern. Eating greens is worthwhile for general nutrition, but it should not be presented as a way to control hot flashes on its own.

7. Berries

Berries provide fiber and other nutrients and can make a plant-based meal or snack more appealing. The listed studies do not establish that berries affect the temperature-regulation changes involved in hot flashes.

Add a serving of fresh or frozen berries to oatmeal, or eat them as a snack. There is no proven berry dose for reducing hot flashes, and you do not need to choose a particular type.

As with oats and leafy greens, the evidence is for a broader dietary approach that included soybeans, not for berries individually. Their role is to support variety, not to replace a treatment that helps you.

Which foods should you limit if you have hot flashes?

Some people notice hot flashes after spicy foods or very hot foods. These are personal reports, not proof that either type causes hot flashes for everyone; the listed trials did not test trigger avoidance.

If you suspect a food, note what you ate, when a hot flash occurred, and whether the pattern repeats. Try a milder or cooler version and see whether it makes a difference, while recognizing that hot flashes can vary for other reasons too.

Alcohol and caffeine are also reported as personal triggers, but they do not need to be avoided automatically. Avoid cutting out broad groups of nutritious foods based on a single episode, especially if doing so makes it harder to eat enough or maintain a varied diet.

Who should be careful, and when should you see a doctor?

Avoid soybeans, edamame, and tofu if you have a soy allergy. If you have thyroid disease, take thyroid medication, or are being treated for breast cancer, ask your clinician how soy foods fit your individual care; do not stop or change medication on your own. The food trials do not establish that soy supplements have the same benefits or safety as soy foods.

See a clinician if hot flashes are new, unexplained, disrupt sleep or daily life, or occur with fever or unexplained weight loss. Medical advice is also appropriate for symptoms during pregnancy or breastfeeding, or in a child, because hot flashes can have causes other than menopause. Seek urgent care for symptoms accompanied by chest pain, severe shortness of breath, or fainting.

If hot flashes remain bothersome, a clinician can discuss established treatment options and whether a dietary change is suitable alongside them. Food can be one part of a plan, but it does not replace an assessment when symptoms need medical attention.
