Zinc is an essential mineral that plays a crucial role in many bodily functions, including immune system function, wound healing, and cell growth and division. Foods that are high in zinc can help to ensure that the body gets enough of this important mineral.
According to the National Institutes of Health, the recommended dietary allowance (RDA) of zinc for adult men is 11 mg/day, and for adult women, it is 8 mg/day. However, many people do not consume enough zinc in their diets, which can lead to zinc deficiency and a range of negative health outcomes. (1)
Consuming foods that are high in zinc can help to ensure that the body gets enough of this important mineral. Zinc plays a crucial role in immune system function, wound healing, and cell growth and division. By promoting a healthy immune system, reducing inflammation, and supporting wound healing, zinc-rich foods can be an important aspect of maintaining good overall health and wellbeing.
Let Us See the Best Natural Sources of Zinc
1.Meat
Meat is one of the best sources of zinc, a mineral that plays a crucial role in various bodily functions such as immune system function, wound healing, and DNA synthesis. Red meat is a rich source of zinc, with a 100-gram serving of beef providing approximately 4.8 mg of zinc, which is around 44% of the recommended daily intake of zinc for adults. Other types of meat, such as pork and lamb, also contain significant amounts of zinc.
Studies have shown that the zinc in meat is highly bioavailable, meaning that it can be easily absorbed and utilized by the body. This makes meat an excellent natural source of zinc, especially for individuals who have difficulty obtaining zinc from other sources.
In addition to red meat, other animal-based foods such as poultry and seafood are also good sources of zinc. Chicken, for example, provides around 1.3 mg of zinc per 100-gram serving, while shellfish such as oysters and crab contain even higher amounts of zinc, with some varieties providing up to 7 mg of zinc per 100-gram serving.

- Crab: A 3-ounce serving of cooked crab contains about 5.7 milligrams of zinc.
- Lobster: A 3-ounce serving of cooked lobster contains about 3.4 milligrams of zinc.
- Mussels: A 3-ounce serving of cooked mussels contains about 2.3 milligrams of zinc.
- Oysters and crab contain up to 7 mg of zinc per 100-gram serving.
3. Legumes
Legumes, such as lentils, chickpeas, and beans, are a great source of plant-based protein and fiber. They are also an excellent source of zinc, with some varieties containing as much as 20% of the recommended daily value per serving. Legumes can be consumed in a variety of forms, such as in soups, stews, salads, and as a side dish. Incorporating legumes into your diet can provide a wide range of health benefits, including improved heart health, digestion, and weight management.
4. Seeds
Seeds are another great source of zinc, particularly pumpkin seeds. One ounce (28 grams) of pumpkin seeds contains about 2.2 mg of zinc. Other seeds high in zinc include hemp seeds, sesame seeds, and flaxseeds. Additionally, seeds are a good source of other important nutrients like fiber, healthy fats, and various vitamins and minerals. Incorporating a variety of seeds into your diet can help increase your overall zinc intake and provide other health benefits.
5. Nuts; Peanuts especially
Nuts and peanuts are great sources of zinc, with cashews, almonds, and peanuts being particularly high in zinc. Other types of nuts that are good sources of zinc include pine nuts, pecans, and walnuts.
In addition to zinc, nuts and peanuts are also rich in other essential nutrients such as healthy fats, protein, fiber, and antioxidants. Studies have shown that consuming nuts and peanuts regularly can help reduce the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer.
For example, a study published in the New England Journal of Medicine found that people who ate nuts regularly had a lower risk of heart disease and other chronic diseases compared to those who didn’t eat nuts.
6. Dairy Products
Dairy products zinc rich foods. Some examples of dairy products that are high in zinc include cheese, milk, and yogurt. However, it’s important to note that the zinc content of dairy products can vary based on factors such as the processing method and the type of dairy product.
For example, some types of cheese, such as cheddar and Swiss, can be good sources of zinc. A 1-ounce (28-gram) serving of cheddar cheese contains about 0.9 mg of zinc, while the same amount of Swiss cheese contains about 0.6 mg of zinc. Milk and yogurt can also be good sources of zinc, with 1 cup of milk containing about 0.9 mg of zinc and 1 cup of plain yogurt containing about 1.7 mg of zinc. (3)
7. Eggs
Eggs are a good source of zinc, with a medium-sized egg containing around 5% of the recommended daily intake. Zinc is found in the yolk of the egg, so consuming the whole egg is important to get the full benefits. Eggs are also a good source of protein, vitamins, and minerals, making them a nutritious addition to any diet.
Additionally, eggs are versatile and can be prepared in a variety of ways, making them a convenient and tasty option for increasing zinc intake. Research has also shown that consuming eggs as part of a healthy diet can help support healthy cholesterol levels and promote weight management.
One medium-sized egg contains about 0.6 milligrams of zinc, which is around 5% of the recommended daily intake for adults. Research has shown that consuming eggs regularly can increase zinc levels in the body and improve overall nutritional status. A study published in the Journal of Nutrition found that adults who ate two eggs per day for 12 weeks had higher levels of zinc in their bodies compared to those who didn’t eat eggs.
8. Whole wheat

These vegetables are not only great sources of zinc, but also offer a variety of health benefits, including improved digestion, lowered risk of chronic diseases, and enhanced immune function.
10. Dark Chocolate
Dark chocolate is a delicious treat that also happens to be high in zinc. The higher the cocoa content, the more zinc the chocolate will contain. Dark chocolate is also a good source of iron, copper, and antioxidants.
Studies have shown that consuming dark chocolate in moderation may have health benefits, such as reducing inflammation, improving heart health, and boosting brain function. However, it is important to keep in mind that chocolate is also high in calories and should be consumed in moderation as part of a balanced diet.
Several studies have investigated the potential health benefits of dark chocolate consumption. A 2012 review published in the British Journal of Nutrition found that consuming dark chocolate can lead to reductions in inflammation markers in the body, which may help to reduce the risk of chronic diseases such as cardiovascular disease and diabetes.
Another study published in the Journal of Nutrition found that consuming dark chocolate improved markers of heart health, including reducing blood pressure and improving endothelial function (the ability of blood vessels to dilate and contract).
Furthermore, a 2018 study published in the journal Appetite found that consuming dark chocolate improved cognitive function and mood in healthy adults. The study also found that dark chocolate consumption led to increased levels of the neurotransmitter serotonin, which is associated with improved mood.
Conclusion
In conclusion, zinc is an essential mineral that plays a vital role in many bodily functions, including immunity, metabolism, and wound healing. Consuming foods high in zinc is an effective way to ensure adequate intake of this important nutrient.
Meat, shellfish, legumes, seeds, nuts, dairy, eggs, and whole grains are all excellent natural sources of zinc. Incorporating these foods into your diet can help you meet your daily zinc requirements and promote overall health and wellbeing.
Additionally, dark chocolate is a delicious treat that is also high in zinc and other beneficial nutrients. While it should be consumed in moderation, dark chocolate can be a healthy addition to a well-balanced diet.
Overall, maintaining a balanced and diverse diet that includes a variety of zinc-rich foods is essential for optimal health and wellbeing.
