Tinnitus, characterized by the perception of noise or ringing in the ears without an external source, affects a significant portion of the global population. While there is no definitive cure, emerging research suggests that diet and lifestyle factors may play a role in tinnitus management. This article explores the relationship between diet, lifestyle, and tinnitus, examining the existing evidence and potential mechanisms.
Understanding Tinnitus
Tinnitus is not a disease, but a symptom of an underlying condition affecting the hearing system. It is usually subjective, which is when a person experiences a high-pitched ringing or buzzing noise that occurs even though there is no such sound in reality. These audible experiences can come and go or be constant. However, tinnitus can also be objective, in which there is an actual sound that a doctor can also hear during a physical examination.
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.

Types of Tinnitus
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.
Impact on Quality of Life
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
While food doesn’t take the place of medical intervention, eating wholesome, nutrient-dense food can help aid your body to heal itself and can even help alleviate your tinnitus symptoms.
Macronutrients and Micronutrients
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.

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.
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. For instance, a 2018 study found associations between persistent tinnitus and higher intake of fruits, vegetables, bread, fish, and eggs, while dairy and caffeinated coffee intake were linked to reduced odds of persistent tinnitus. Additionally, higher caffeine intake was associated with a lower risk of incident tinnitus in women.
Important Vitamins and Minerals
Several vitamins and minerals are believed to play a role in maintaining hearing health and potentially alleviating tinnitus symptoms:
- Vitamin B12: 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. In a multivariate model, higher intake of vitamin B12 was associated with reduced odds of tinnitus.
- Zinc: 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: 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.
- Potassium: 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.
Foods to Include in Your Diet
- Fruits and Vegetables: Fruits and veggies are full of vitamins and minerals that help keep your ears healthy. For example, foods rich in vitamins A, C, and E, and magnesium can protect your ears from damage. Certain fruits are found to be particularly helpful when it comes to relieving tinnitus, especially foods that are rich in potassium. These include bananas, pears, and tropical fruits such as pineapples, papayas, and mangoes. These foods help lower the blood pressure and encourage proper blood circulation to the ears.
- Fish: Fish like salmon, tuna, and mackerel have omega-3 fatty acids. These healthy fats help reduce inflammation and improve blood flow in your ears.
- Nuts and Seeds: Nuts and seeds like almonds, walnuts, and flaxseeds are great for your ears.
- Whole Grains: Whole grains like brown rice, oats, and whole wheat bread are good for your blood flow.
- Garlic: You can add garlic to your regular cooking each day to help improve blood flow as well as decreasing any inflammation that you may have in your body. Some people like having a clove of raw garlic first thing in the morning, but that option may be a bit overpowering for others. If you do not particularly fancy the strong taste of garlic, you can opt for daily supplements of odorless garlic.
- Bromelain: Tinnitus can have adverse effects on the body, which can lead to inflammation. However, bromelain, which is found in pineapple, can help reduce inflammation in the body, thus lessening the effects of tinnitus.
Potential Dietary Triggers to Avoid
Potential dietary triggers of tinnitus encompass caffeine, sodium, salicylates, aspartame, sugar, and unhealthy fats. Caffeine, prevalent in beverages like coffee, tea, hot chocolate, and energy drinks, can exacerbate tinnitus symptoms by elevating blood pressure and stimulating nerve cell activity. Sodium, commonly found in processed and fast foods and snack items, can constrict blood vessels and elevate blood pressure, worsening tinnitus symptoms. Salicylates, natural compounds in fruits, vegetables, nuts, and oils, may accumulate in the body and provoke adverse reactions, potentially exacerbating tinnitus symptoms in sensitive individuals. Aspartame, an artificial sweetener, is suspected to be linked to tinnitus due to its potential toxicity to the brain and inner ear, particularly under conditions of heat exposure or prolonged storage. Problems with sugar metabolism, such as hyperinsulinemia, may also contribute to tinnitus symptoms, and adherence to a diabetic diet could alleviate symptoms for some individuals. Unhealthy fats, including saturated and trans fats, can impede circulation and diminish blood flow, potentially intensifying tinnitus severity.
- Salt: Eating too much salt can increase blood pressure, which can make tinnitus worse.
- Caffeine: Drinks with caffeine, like coffee, tea, and soda, can sometimes make tinnitus worse.
- Sugar: Too much sugar can affect your blood flow and make tinnitus worse.
- Alcohol: Drinking too much alcohol can make tinnitus worse.
- Glutamate: 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.
- 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.
- 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.
The Importance of Hydration
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.

Elimination Diet
An elimination diet involves systematically removing specific foods or food groups from one's diet to identify which are causing the problem. The good news is that elimination diets are temporary. We generally recommend avoiding foods in the following categories.
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.
Lifestyle Factors and Tinnitus
Beyond diet, several lifestyle factors can influence tinnitus:
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.
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.
Other Treatment Options for Tinnitus
The National Institute on Deafness and Other Communication Disorders lists the following treatment options that doctors may recommend for someone with tinnitus:
- Treating the underlying issue, such as addressing earwax and jaw joint problems, stopping medications that cause symptoms, or managing blood pressures. 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.
- Sound therapies, including hearing aids to help improve hearing and sound generators to help with sleep. Modern hearing aids not only improve hearing but also offer features specifically designed to reduce tinnitus symptoms. By amplifying external sounds, they help mask the internal noise caused by tinnitus, providing noticeable relief for many people.
- Behavioral therapies, including cognitive behavioral therapy to help reduce negative thoughts about tinnitus and tinnitus retraining therapy that helps the brain to ignore tinnitus sounds.
- Drugs to assist with side effects of tinnitus, such as antidepressants and antianxiety medication.
Researchers are also investigating new treatment strategies, such as noninvasive electrical stimulation and deep brain stimulation.
Seeking Professional Help
Anyone with symptoms of tinnitus should speak with a healthcare professional. A doctor can diagnose the condition and provide a personalized treatment plan to help manage symptoms. People who already have tinnitus should also seek medical advice before beginning to fast. The same is true of people who are considering making other radical changes to their diet. A healthcare professional can help people make changes to their diet without experiencing nutritional imbalances or any other risks to their overall health. Audiologists may also recommend other tinnitus management options such as hearing aids for tinnitus, cognitive behavioral therapy, etc.
