While Cheddar and Mozzarella are good sources (around 3.1 mg/100g), French Maroilles cheese is cited as having the highest zinc content, with about 9 mg per 100g, though specific content varies by cheese type, origin, and milk source, with cow's milk cheeses generally being high.
Cow cheeses generally showed the highest zinc content (1.83–7.75 mg/100 g cheese), followed by sheep cheeses (1.34–3.69 mg/100 g), and cheeses from mixed milk (0.39–4.54 mg/100 g). The only cheese from buffalo milk (Mozzarella di Bufala Campana PDO) showed a zinc content of 2.14 mg/100 g.
To get 100% of your daily zinc, focus on oysters, which are exceptionally rich in zinc, but also incorporate red meat, poultry, seafood (crab, lobster), and plant sources like nuts, legumes (chickpeas, lentils), and whole grains (oats, wheat germ) into a balanced diet, remembering that absorption is best from animal sources.
The food highest in zinc is oysters, which contain significantly more zinc per serving than any other food, followed by other shellfish like crab and lobster, and then red meats such as beef, lamb, and pork. Other excellent sources include poultry, nuts (cashews, pumpkin seeds), legumes (lentils, chickpeas), dairy products, eggs, and fortified cereals, though zinc from plant sources is less easily absorbed.
Safety and side effects
Zinc supplements taken by mouth may cause: Diarrhea. Dizziness.
Early symptoms of zinc deficiency include a loss of appetite and, in infants and children, slowed growth and development. People may lose their hair in patches. They may feel sluggish and irritable. Taste and smell may be impaired.
If you have vitamin B12–deficiency anemia, you may have the typical symptoms of anemia at first, such as fatigue, paleness, shortness of breath, headaches, or dizziness. If left untreated, you may start to notice brain and nervous system symptoms.
Below are the 10 best foods that are high in zinc.
Conditions that may cause zinc deficiency include:
Zinc is an essential micronutrient with many health benefits. Fruits that are richest in zinc include pomegranate, wild blueberries, avocado, and others. Zinc is an essential micronutrient with many health benefits. It is good for your immune system and cell growth.
One serving of chickpeas (100 grams) contains 1.5 milligrams of zinc, and a half-cup of kidney beans has 0.9 milligrams.
Given that zinc aids in the rapid division and proliferation of hair cells, it, therefore, promotes the growth of strong and resilient hair strands and contributes to overall hair health. It provides the building blocks needed for healthy follicle development and helps to fortify the foundation from which hair grows.
The common plant foods highest in zinc are legumes, nuts, seeds, and oatmeal. The table below shows the zinc content of selected plant foods (USDA National Nutrient Database for Standard Reference).
Phytates (phytic acid) in whole grains, seeds, legumes, some nuts—can decrease the absorption of iron, zinc, magnesium, and calcium. [2,3] Saponins in legumes, whole grains—can interfere with normal nutrient absorption.
To know if you have a zinc deficiency, look for symptoms like hair loss, skin rashes (especially around mouth/nose/buttocks), slow wound healing, frequent infections, diarrhea, loss of appetite, and changes in taste or smell, as wells as fatigue, irritability, and developmental delays in children. A doctor can confirm with blood tests, but often diagnoses based on symptoms, dietary history, and risk factors like poor diet or absorption issues, as blood tests can be tricky to interpret.
Thus, in general, increased dietary protein leads to increased zinc intake and a higher bioavailability of the zinc provided. The type of protein in a meal will also affect zinc bioavailability.
In serious cases, medicines called chelators, which remove zinc from the bloodstream may be needed, and the person may need to be hospitalized.
To get 100% of your daily zinc, focus on oysters, which are exceptionally rich in zinc, but also incorporate red meat, poultry, seafood (crab, lobster), and plant sources like nuts, legumes (chickpeas, lentils), and whole grains (oats, wheat germ) into a balanced diet, remembering that absorption is best from animal sources.

Our study successfully supplemented vitamin D deficiency through vitamin D monotherapy. This significantly reduced the recurrence rate of vertigo. Furthermore, in our study, neither the vitamin D group nor the placebo group reported any adverse effects.
People need vitamin B-12 for the brain to work well. If not treated, vitamin B-12 deficiency can lead to issues with the nerves, brain or spinal cord. These might include lasting tingling in the hands and feet or trouble with balance.
