Tinnitus, the perception of noise or ringing in the ears without an external source, affects a significant portion of the global population. It is a common condition, affecting up to 1 in 4 adults. While there is no definitive cure, emerging research suggests that diet and lifestyle factors may play a role in tinnitus management. Tinnitus is not a disease, but it can be a sign that something is wrong with your ears or your hearing. This article explores the potential role of diet in tinnitus and other tips for managing the condition.
Understanding Tinnitus
Tinnitus is characterized by a persistent ringing or buzzing in the ears, although the sound has no external source. Its manifestations vary widely, from occasional buzzing to constant ringing, impacting various aspects of daily life such as concentration and sleep quality. Studies estimate that about 10-15% of people worldwide experience some degrees of tinnitus with 1-2% enduring severe and persistent symptoms.
Tinnitus presents as a multifaceted symptom with diverse potential causes and mechanisms. It can stem from cochlear dysfunction, such as impairment to the outer hair cells in the inner ear, resulting in aberrant neural synchrony and alterations in tonotopic representation. However, tinnitus can also emanate from various relevant anatomical structures along the central auditory pathways, with ample evidence indicating that many tinnitus forms arise from intricate interactions between peripheral and central mechanisms.
Beyond cochlear dysfunction, various factors may induce tinnitus, including exposure to loud noises, hearing impairment, emotional distress, and somatosensory influences. Conceptually, tinnitus can be viewed as a pathology rooted in neural plasticity, with both molecular and systemic components. It encompasses a cochlear component linked to its onset phase and a central aspect tied to its long-term maintenance.
Insights from animal models of tinnitus have been instrumental in identifying the location and characteristics of underlying defects, revealing heightened spontaneous activity in regions like the dorsal cochlear nucleus, inferior colliculus, and primary auditory cortex, alongside increased neural synchrony and bursting activity along the auditory pathway. Spontaneous otoacoustic emissions (SOAEs) represent one potential source of tinnitus, termed cochlear mechanical tinnitus. They are typically mild occurrences, often encountered in individuals with normal hearing and those affected by middle-ear ailments.

Tinnitus encompasses various types, with subjective and objective tinnitus being the primary classifications. Subjective tinnitus comprises approximately 99% of cases and is audible solely to the individual experiencing it. It can arise from diverse factors such as sudden exposure to loud noises, aging, hearing impairment, or conditions like Ménière's disease. In contrast, objective tinnitus, a rare occurrence affecting only about 1% of tinnitus sufferers, can be heard by the affected person and others, including medical professionals employing a stethoscope. Typically, objective tinnitus stems from vascular anomalies, neurological disorders affecting facial muscles, or patulous eustachian tubes, a condition characterized by the persistent opening of these tubes.
Additional varieties of tinnitus include somatic tinnitus, associated with movements or tactile sensations, often triggered by muscle spasms, neck misalignments, or dental issues. Pulsatile tinnitus, exhibiting a rhythmic pattern synchronized with the heart's beats, indicates alterations in blood flow near the ear. Low-frequency tinnitus, affecting individuals profoundly with tones corresponding to the lowest octaves on a piano, manifests as humming, murmuring, rumbling, or deep droning sounds. Musical tinnitus, also known as musical hallucinations or auditory imagery, is a less common type characterized by the perception of simple tones or layered melodies, prevalent among individuals with prolonged hearing loss and tinnitus history. Treatment strategies for tinnitus vary depending on its type and underlying cause.
Tinnitus profoundly impacts individuals' quality of life, affecting diverse facets such as psychological well-being, emotional stability, sleep patterns, auditory functions, and overall health-related quality of life (HRQoL). Its presence often correlates with lower HRQoL due to associated factors like hearing loss, ototoxicity, head injury, and depression, presenting a formidable challenge to individuals' overall well-being. Studies underscore the emotional toll of tinnitus, revealing a spectrum of reactions including difficulty concentrating, frustration, anger, and even depression, all of which significantly disrupt daily functioning and emotional equilibrium. The adverse effects of tinnitus extend beyond the auditory realm, encompassing psychological and emotional distress, sleep disturbances, and broader health repercussions. Moreover, tinnitus can prove debilitating, impeding individuals' ability to focus, sleep, and participate in routine activities, consequently diminishing their overall quality of life.
The Role of Diet in Tinnitus Management
Did you know that what you eat can affect your tinnitus? It’s true! Just like how a healthy diet can keep your body in good shape, it can also keep your ears healthy. Some people with tinnitus believe certain foods or drinks can exacerbate or reduce their symptoms. However, research on the relationship between diet and tinnitus severity is limited. Nonetheless, certain dietary choices have gained a reputation for their potential impact on tinnitus, even though their effects may vary from person to person.
Key Nutrients and Their Impact
Micronutrients, comprising vitamins and minerals, are indispensable for the body despite being needed in minute quantities. They fulfill various functions, facilitating enzyme and hormone production essential for normal growth and development. Water-soluble vitamins, such as vitamins B and C, dissolve in water and necessitate daily replenishment as they are not stored in the body. In contrast, fat-soluble vitamins like A, D, E, and K dissolve in fat and can be stored for later use. Microminerals such as calcium, magnesium, sodium, and potassium are crucial for muscle and bone health and contribute to blood pressure regulation. Trace minerals like iron, manganese, copper, zinc, and selenium play pivotal roles in muscle health, nervous system function, and cell repair.

Macronutrients: Carbohydrates serve as the primary energy source for the body, vital for various physiological functions including central nervous system, brain, kidney, and muscle function. They can be stored for later use and play a key role in intestinal health and waste elimination. Carbohydrate sources encompass simple sugars in honey and fruits and complex starches in grains, potatoes, and starchy vegetables. Proteins, essential for growth, tissue repair, and maintaining lean body mass, are composed of amino acids, some of which must be acquired through diet. Protein-rich foods include animal products like meat, poultry, fish, dairy, and plant-based sources like beans, lentils, nuts, seeds, and soy. Fats are vital for energy storage, organ cushioning, hormone synthesis, vitamin absorption, and cell membrane integrity. While trans fats should be limited, unsaturated fats in olive oil, avocados, and nuts benefit heart health.
Specific Foods to Include
Eating lots of fresh fruits and vegetables is great for your ears. These foods have vitamins and minerals that help keep your ears healthy. Encouragingly, there is evidence that both hearing loss and tinnitus may be associated with modifiable lifestyle factors including noise exposure, smoking, alcohol consumption, exercise, and diet, offering possibilities for prevention.
- Fruits and Vegetables: Fruits and vegetables, especially those that are a good source of antioxidants, are believed to reduce oxidative stress and inflammation, which can help ease symptoms.
- Vitamin B12 Rich Foods: Some studies have also linked foods high in vitamin B12 (like fish and organ meats) with reduced tinnitus severity. Vitamin B12 can help alleviate your tinnitus symptoms that are a result of noise damage. You can find vitamin B12 in mackerel, salmon, chicken, beef, and eggs.
- Potassium-Rich Foods: Foods with plenty of potassium, such as bananas and tropical fruits, may benefit your overall hearing health. potassium helps regulate the proper flow of fluids throughout the body. Potassium-rich foods that may help alleviate your symptoms include apricots, sweet potatoes, pears, papayas, bananas, yogurt, spinach, mangos, and apples.
- Zinc-Enriched Food Items: You can find this helpful nutrient in seafood such as oysters, or red meat such as beef as well as lamb. For vegetarian options for Zinc-enriched food items, you can opt for spinach which have zinc as well as iron, which improves blood supply and further enhances blood circulation that aids in tinnitus relief. Sometimes ringing in the ears can be caused by low levels of zinc, which is responsible for healing and cell growth. So make sure you keep your levels up by eating plenty of nuts, dark chocolate, yogurt, chicken, beef, spinach, lamb, and shellfish.
- Folate Enriched Foods: Folate helps improve blood flow to the inner ear by increasing circulation and can help improve tinnitus, sudden hearing loss, and age-related hearing loss. Get your daily dose of folate by eating plenty of beans, spinach, romaine lettuce, broccoli, turnip greens, asparagus, and bok choy.
- Omega-3 Fatty Acids: Fish like salmon and nuts like almonds have omega-3 fatty acids. These are good fats that can help reduce inflammation in your ears.
- Whole Grains: Whole grains like brown rice, oatmeal, and whole wheat bread have lots of vitamins and minerals.
Foods to Avoid or Limit
Stay away from common trigger foods like caffeine, salty foods, and any meals with artificial additives. If you suspect that a particular food is contributing to your tinnitus, avoid eating any for a week. Then reintroduce the food and take notice if you experience any adverse effects. Here, I introduce some important information about foods that trigger tinnitus, not just what they are, but why they make tinnitus worse. Once you understand this information, it will help you understand the why the best tinnitus diet is anti-inflammatory in nature. A tinnitus diet is not for weight loss; it’s to help you avoid tinnitus trigger foods and improve your brain health.
- Caffeine: Caffeine is in coffee, tea, soda, and even chocolate. Too much caffeine can make tinnitus worse because it can make you feel more anxious and stressed. Higher caffeine intake can often exacerbate tinnitus symptoms. It can also disrupt sleep, which itself can trigger the migraine reaction in the brain. Some studies show caffeine intake may help tinnitus. How does this make sense, when we know it's on the bad list? The reason is that your brain becomes addicted to caffeine. When you don't have it, you get symptoms like headache or tinnitus.
- Salt: Eating too much salt can raise your blood pressure. High blood pressure can make tinnitus worse because it can reduce the blood flow to your ears. Excessive salt intake (sodium chloride) can lead to fluid retention, electrolyte imbalances, and increased blood pressure, all of which are potential tinnitus triggers. The effects can trigger the migraine process in the brain. Avoiding high salt intake does not just mean avoiding regular table salt.
- Sugar: Too much sugar can lead to problems with your blood sugar levels. This can affect your ears and make tinnitus worse. High blood sugar-or more commonly, sharp fluctuations in blood sugar-can trigger tinnitus. Sudden changes can activate stress hormones like cortisol and adrenaline, which affect blood vessel tone and blood flow in the brain and inner ear. Cutting out sugar can help stabilize blood sugar and reduce the chances of triggering the migraine process.
- Alcohol: Beer and wine frequently trigger the migraine reaction in the brain, worsening tinnitus. This is because fermented products are foods that trigger tinnitus.
- Fatty Foods: Fatty foods do not necessarily trigger tinnitus, but a dietary pattern high in fat can make tinnitus worse due to its effect on blood vessels and inner ear circulation. A high fat diet or one that raises bad cholesterol (like red meat intake) can lead to arterial disease, which reduces blood flow to the inner ear. Trans fats, such as seen in fried foods, can trigger an inflammatory reaction in the body. Inflammation in general is one of the risk factors for triggering the migraine reaction.
- Artificial Sweeteners: Artificial sweeteners like aspartame should be avoided by tinnitus patients. Aspartame can trigger the migraine reaction by altering neurotransmitter levels in the brain.
- Glutamate: Glutamate is a neurotransmitter in the brain involved in signal transmission between neurons and plays a crucial role in various brain functions. Glutamate is the “G” in MSG. It is used in processed foods as a preservative and flavor enhancer. Certain foods sometimes hide MSG under different names like autolyzed yeast powder.
- Tyramine: Tyramine is a compound found in certain foods (such as fermented foods) where there is breakdown of the amino acid tyrosine. It is known to trigger the migraine reaction in the brain due to its ability to cause blood vessels to constrict and then expand, leading to changes in blood flow.
- Histamine: Histamine is a compound involved in various physiological processes, including immune response and neurotransmission. In the context of tinnitus, histamine act as a vasodilator, promoting blood vessel dilation and potentially contributing to the migraine reaction.
The Importance of Hydration
Drinking enough water is very important for your overall health, including your ear health. When you’re dehydrated, it can affect your ears and make tinnitus worse. Dehydration can contribute to tinnitus in a number of ways. For instance, dehydration can directly affect the fluid filled structures of the inner ear. Dehydration reduces blood flow, leading to poor blood circulation to the inner ear.
Hydration is pivotal in managing tinnitus, as dehydration can worsen symptoms and contribute to conditions that trigger tinnitus, such as high blood pressure, compromised hearing health, and ear infections. Ensuring adequate hydration is essential for sustaining healthy hearing, as the ears rely on fluid for optimal function. Studies have indicated that decreased vitamins B2, B3, water, and protein intake may correlate with tinnitus and related discomfort. Moreover, research conducted in Korea revealed a significant association between water intake and tinnitus, with individuals experiencing tinnitus displaying lower water consumption. This finding underscores the significance of maintaining adequate hydration, particularly during middle age when many individuals are engaged in active careers.

Dietary Patterns and Tinnitus
Research on dietary patterns and tinnitus aims to uncover potential relationships between them. While evidence linking specific foods or drinks to tinnitus severity remains inconsistent, some studies suggest dietary factors may influence conditions like Ménière’s disease, affecting the inner ear. However, conclusive links are lacking for other types of tinnitus, with research presenting contradictory findings.
- Ketogenic (Keto): May helpful in reducing tinnitus by decreasing inflammation and stabilizing blood sugar levels, which can mitigate triggers for the migraine reaction.
- Mediterranean: May help with people with tinnitus due to its emphasis on anti-inflammatory foods rich in antioxidants, healthy fats, and omega-3 fatty acids, potentially reducing inflammation and oxidative stress associated with migraine onset.
- Diabetic (Low Gl): May aid in tinnitus management by promoting stable blood sugar levels and reducing fluctuations. “Low GI” stands for low glycemic index.
- Anti-neuroinflammatory (ANI): May assist with tinnitus by incorporating foods rich in antioxidant and anti-inflammatory compounds. These can help reduce inflammation in the brain and potentially alleviate the migraine reaction that drives tinnitus.
- Antioxidant-rich: May benefit tinnitus sufferers by reducing oxidative stress and inflammation in the body, potentially decreasing the frequency and severity of tinnitus attacks. This diet is also good for hearing health and may protect against toxic noise exposure.
The best tinnitus diet is usual one or a combination of these. Most dietary supplements that helps with migraine will also help with tinnitus. Antioxidant supplements are great natural remedies for tinnitus and for hearing health. For instance, they can help prevent the progressive sensorineural hearing loss seen with aging or mitigate noise induced hearing loss.
Beyond Diet: Additional Management Strategies
In addition to dietary modifications, several other strategies can help manage tinnitus symptoms effectively.
Stress Management
Effective stress management techniques can significantly ameliorate tinnitus symptoms and alleviate the associated distress. Tinnitus and stress share a close relationship, with stress often exacerbating tinnitus symptoms, while the condition itself can induce stress and anxiety. The research underscores stress as a trigger for tinnitus or a factor in worsening existing symptoms, creating a cyclic interplay between stress and tinnitus. An array of stress management strategies can be implemented to disrupt this cycle. Relaxation techniques, such as deep breathing exercises, visualization, and self-hypnosis, have effectively reduced stress levels and tinnitus symptoms. Mindfulness-based tinnitus stress reduction programs, which emphasize deep breathing, yoga, relaxation, and meditation, offer promise in tinnitus management. Additionally, mitigating stress through exercise, problem-solving, engaging in enjoyable activities, and socializing can contribute to tinnitus management. Activities that reduce overall stress levels may positively impact tinnitus perception and reactions, given the interconnectedness of stress and tinnitus. Cognitive-behavioral therapy (CBT) serves as another valuable tool in tinnitus management by assisting individuals in identifying and reframing negative thoughts regarding tinnitus into more constructive ones. Often utilized alongside mindfulness programs, CBT has demonstrated efficacy in reducing depression and anxiety, enhancing social functioning, and improving overall mental well-being. Furthermore, adopting a daily exercise regimen, learning to regulate stress responses, and seeking support from healthcare professionals or tinnitus support groups are valuable components of stress and tinnitus management.
- Mindfulness-Based Stress Reduction (MBSR): A therapy that emphasizes “mindfulness” - a deliberate and non-judgemental awareness of one’s physical sensations, sensory perceptions, emotional reactions, and cognitive processes. Rather than struggling (often in vain) to ignore tinnitus, MBSR teaches patients to wholly accept, embrace, and control their experience. In doing so, patients put themselves in a better position to manage their condition.
- Acceptance and Commitment Therapy (ACT): Like other mindful-based approaches, ACT emphasizes the need to reduce experiential avoidance of tinnitus. Patients are taught to fully experience thoughts, perceptions, and emotions in a direct, non-judgemental way.
- Biofeedback: Biofeedback is relaxation technique that teaches patients to control certain autonomic body functions, such as pulse, muscle tension, and skin temperature. The goal of biofeedback is to help people manage stress and anxiety by changing the body’s reaction to these negative influences.
- Hypnotherapy: Hypnotherapy has been shown to promote relaxation and reduce anxiety. It may also alter neural connections between areas of the brain.
Noise Management
Some find it helpful to use background noise, such as white noise machines or calming music, to mask the tinnitus sounds and make them less noticeable.
Hearing Protection
It may help to protect the ears from loud sounds. People can ask their doctor for advice on the best ear protection for concerts, events, or their workplace.
Social Activities and Hobbies
Isolation can negatively impact mental health, and may cause a person to focus more on their tinnitus. Social experiences and hobbies may provide something positive to focus on. Many tinnitus patients report feelings of social isolation, due to difficulties with interpersonal communication, sound sensitivity, and/or irritability. Unfortunately, removing yourself from social situations creates a cycle of negative reinforcements that may make tinnitus an even larger problem. Social experiences with friends, family, and peers can positively distract patients from their tinnitus symptoms. They can also improve emotional wellness, general feelings of contentment and optimism. Some patients believe that having tinnitus means they must give up activities that they enjoy. That is absolutely not the case. Some activities may even provide the benefit of directly masking the sound of tinnitus. Tinnitus patients may need to make adjustments or take certain precautions prior to engaging in specific recreational activities - particularly activities that involve loud noise.
Physical Activity and Exercise
The influence of physical activity and exercise on tinnitus is a multifaceted issue characterized by both positive and negative ramifications. On one hand, regular physical activity has demonstrated notable benefits in enhancing health-related and overall quality of life while concurrently diminishing levels of tinnitus distress. A study revealed a significant association between higher physical activity levels and improved health-related and global quality of life, coupled with reduced tinnitus distress. Furthermore, physical activity emerged as a significant factor contributing to variations in tinnitus severity, indicating its potential as a management strategy for affected individuals. Conversely, certain forms of exercise can precipitate or exacerbate tinnitus symptoms. High-impact aerobics, such as running, basketball, football, and soccer, can potentially dislodge otoconia and calcium crystals within the ears, leading to inner ear issues and tinnitus exacerbations. Additionally, exerting strain while lifting weights or engaging in heavy exertions can elevate intracranial pressure, exerting pressure on the ears and potentially resulting in perilymph fistula, which is a tear in the membrane separating the middle and inner ear, manifesting as dizziness, tinnitus, and heightened hearing sensitivity. Hence, it is imperative to recognize the potential impact of exercise on tinnitus and seek medical guidance if experiencing ringing or buzzing in the ears following physical activity.
Medical Treatments
There are also medical treatments for tinnitus, such as sound therapy, behavioral therapies, and medications. Audiologists may also recommend other tinnitus management options such as hearing aids for tinnitus, cognitive behavioral therapy, etc. Ear wax removal may also be performed to help manage tinnitus if it is established that the ringing in the ears is caused by impacted ear wax.
The Importance of Symptom Tracking and Professional Guidance
If you have tinnitus, keep a food diary. Write down what you eat and drink every day and see if you notice any changes in your tinnitus. People who are curious about what worsens their own tinnitus can:
- Start a symptom diary: People can monitor their tinnitus by documenting the date, time, and perceived severity of their symptoms, as well as factors that might influence these symptoms, such as stress levels, or transitions from loud to quiet environments.
- Use a severity scale: People can implement a straightforward rating system to gauge the severity of tinnitus symptoms. For instance, they could rate the symptoms on a scale from 1 (mild) to 10 (severe).
- Track dietary choices: People who believe certain foods worsen their tinnitus can also record the types and quantities of foods and beverages they consume.
- Identify patterns: After consistently recording symptoms and dietary preferences, review the diary entries for recurring patterns or trends.
If you have tinnitus and you think your diet might be affecting it, talk to an audiologist. They can help you understand more about how food and drinks can impact your ear health. They can also give you advice on how to change your diet to help reduce your tinnitus symptoms. Individuals should consult a healthcare professional or audiologist if they identify potential links between tinnitus symptoms and specific foods or triggers. These experts can provide guidance, conduct further assessments, and assist in creating a personalized plan to manage tinnitus effectively.
