The food we eat directly affects our overall well-being, and that includes our hearing health. Just as certain foods are known to benefit vision, nutrition plays a vital role in maintaining and even improving auditory function. Incorporating specific nutrients and dietary patterns can potentially protect your ears from damage and delay the onset of age-related hearing loss.
The Link Between Diet and Hearing Health
Hearing is one of the most important senses for social communication and cognitive functions. Sensorineural hearing loss can have adverse and permanent consequences in all aspects of personal and social life. Research suggests a strong connection between a balanced diet rich in essential nutrients and improved hearing health. By providing our bodies with the necessary building blocks, we can support the health of our auditory system.
Studies have shown that certain dietary patterns can protect against high blood pressure, inflammation, and other undesirable conditions. Scientists have investigated whether these patterns might also affect hearing. A research team led by Drs. Gary C. Curhan and Sharon G. Curhan analyzed data from about 71,000 women who participated in the Nurses’ Health Study II between 1991 and 2013. The study found that women whose dietary patterns most resembled the alternate Mediterranean diet (AMED) or Dietary Approaches to Stop Hypertension (DASH) had about a 30% lower risk of hearing loss than women whose diets least resembled them.
Maintaining good overall health is beneficial for our hearing health as well. Certain dietary patterns seem to protect against high blood pressure, inflammation, and other undesirable conditions.
Key Nutrients for Hearing Health
Several nutrients are particularly important for maintaining and improving hearing health. These include vitamins, minerals, and fatty acids that support the function of the inner ear and protect it from damage.

Vitamins
- Vitamin B12: Found in meat, eggs, poultry, dairy products, and other foods from animals, vitamin B12 is crucial for nerve function. Strict vegetarians and vegans are at a higher risk of developing a B12 deficiency, which can affect balance and potentially contribute to hearing problems.
- Folate/Folic Acid/Vitamin B9: Abundant in spinach, bok choy, romaine lettuce, asparagus, turnip greens, broccoli, and beans (especially lentils and garbanzo beans), folate has been shown to improve tinnitus, as well as sudden and age-related hearing loss. Folate helps increase circulation, improving blood flow to the inner ear.
- Vitamin C: A potent antioxidant that helps reduce inflammation and protects cells from damage caused by oxidative stress. It is present in many fruits and vegetables such as oranges, lemons and tomatoes, but it is not present in grains at all.
- Vitamin A: Causes yellow, green and red pigments in plants such as carrots, apricots and vegetables. Vitamin A, in the form of its active metabolite or retinoic acid, is essential for the normal development of the inner ear, in addition to providing a protective role for the auditory system against continuous exposure to environmental sounds.
Minerals
- Potassium: Found in bananas, potatoes, spinach, lima beans, tomatoes, raisins, apricots, melons, oranges, yogurt, and low-fat milk, potassium regulates the amount of fluid in your blood and body tissue. Fluid in the inner ear is dependent upon a rich supply of potassium, especially in the part of the ear that translates noises into electrical impulses for the brain.
- Magnesium: Included in fruits and vegetables, such as bananas, artichokes, potatoes, spinach, tomatoes, and broccoli, magnesium helps combat free radicals and acts as a protective barrier for the delicate hair cells in the inner ear. It also reduces vascular contractions caused by sound, which occur due to the formation of free radicals.
- Zinc: Found in protein-rich foods like oysters, grass-fed beef, pumpkin seeds, tahini (ground sesame seeds), cashews, almonds, spinach, and dark chocolate, zinc boosts the body’s immune system and is responsible for cell growth and healing. It has shown promise in improving sudden sensorineural hearing loss (SSNHL) and may be effective in treating tinnitus in individuals with normal hearing.
- Iron: Low iron levels can hinder the blood flow to your cochlea, the spiral-shaped part of your inner ear responsible for hearing. So, don’t skimp on iron-rich foods like beef, salmon, and legumes.
Fatty Acids
- Omega 3s: Found in many fish (most notably salmon), walnuts, and flax and chia seeds, omega-3 fatty acids have anti-inflammatory properties that can benefit blood flow to the inner ear. Regular consumption of fish has been associated with a lower risk of hearing loss in women.
Antioxidants
Antioxidants like B12, folic acid, Omega 3s, and vitamin A are all important because they help fight off damaging free radicals. The formation of free radicals in the cochlea of the inner ear is one of the causes of sensorineural hearing loss. The most effective strategy to prevent sensorineural hearing loss is to inhibit the formation of free radicals in the cochlea, which are caused by aging, exposure to noise, ototoxic factors and other environmental damages.
Foods to Include in Your Diet
Incorporating a variety of nutrient-rich foods into your diet can support and improve your hearing health. Here are some specific foods to consider:
- Fatty Fish: Salmon, mackerel, and sardines are packed with omega-3 fatty acids, which have anti-inflammatory properties that benefit blood flow to the inner ear.
- Spinach: This nutritional powerhouse is rich in folate, which is associated with a reduced risk of age-related hearing loss.
- Blueberries: These berries are full of antioxidants that can help protect the ears from oxidative stress and potential damage caused by free radicals.
- Nuts and Seeds: Almonds, walnuts, and flaxseeds are excellent sources of nutrients, including vitamin E, which may reduce the risk of age-related hearing loss.
- Citrus Fruits: Oranges and other citrus fruits are rich in vitamin C, a potent antioxidant that helps reduce inflammation and protects cells from damage caused by oxidative stress.
- Dark Chocolate: Dark chocolate, particularly varieties with high cocoa content, can provide your body with antioxidants known as flavonoids, which can help maintain healthy blood flow to the ears.
- Green Tea: Green tea has anti-inflammatory properties that are particularly valuable for protecting the auditory system against age-related damage.
- Bananas: As a popular superfood, bananas should be consumed every day to stay healthy. They are also a good source of potassium and magnesium.
- Broccoli: Broccoli contains fiber and vitamin C and can stop the formation of free radicals in your body, which can break down your cells, resulting in several diseases. It is also a good source of magnesium.
- Garlic: Garlic has multiple health benefits. It is excellent for your heart and is extremely effective in lowering cholesterol.
- Whole Grains: Whole grains can help maintain nerve function and protect the hair cells in the inner ear while they are exposed to loud noise.
Foods to Limit or Avoid
Certain foods can negatively impact your hearing health and should be limited or avoided. These include:
- Vegetable Oils: These oils contain too many Omega 6 fatty acids. Instead, use EVOO or Canola oil, which are rich in Omega 3s.
- Margarine/Partially Hydrogenated Oils: Found mostly in processed foods, these oils can contribute to inflammation and other health problems.
- High-Fat Meats: Especially those treated with nitrates/nitrites (preservatives), high-fat meats can negatively impact overall health.
- Whole/2% Milk: Consider using a dairy substitute such as almond, rice, or coconut milk.
- Cream Cheese: Replace with goat cheese or part skim organic ricotta.
- Processed Cheeses: Opt for organic/grass-fed hard cheese instead of processed cheeses like American.
- Sugar and Artificial Sweeteners: Limit these or replace with Stevia, honey, or real maple syrup. High sugar intake can lead to spikes in blood glucose levels, which can damage the small blood vessels throughout your body - including those in your ears.
- Refined Carbohydrates: These include white breads, pasta, and any foods containing “enriched” flour, which means nutrients have been removed from the grain.
- Sodium: Maintain a higher ratio of potassium to sodium. Packaged and processed foods have WAY too much sodium. Consuming too much salt can lead to fluid retention in your body.
- Chemicals/Pesticides: Wash your produce thoroughly and buy organic when you can to minimize exposure to harmful chemicals.
- High-Cholesterol Foods: If you’re grappling with tinnitus, you’ll want to be extra cautious about high-cholesterol foods, carb overload, and caffeine, as they can exacerbate your symptoms.
As a general rule, eat food the way it was meant to be eaten. Food doesn't grow in a box, so don't buy it that way! Use herbs instead of heavy sauces and creams for added flavor.
Additional Factors for Hearing Health
In addition to diet, several other factors can influence your hearing health:

- Hydration: Dehydration can cause a reduction in the amount of fluid available for the inner ear, which is essential for transmitting sound signals to the brain.
- Exercise: Regular exercise improves blood circulation, which is beneficial for the tiny blood vessels in your ears.
- Lifestyle: Healthy lifestyle factors including continuous physical activity, good sleep quality, quitting smoking, stay away from stressful factors or relaxation, and avoiding exposure to environmental noise.
- Melatonin: Melatonin has a protective role in the hearing system and is a very effective factor in preventing permanent sensorineural hearing loss . It is produced only in the darkness of the night, so it is necessary to have enough night sleep.
