10 Best Zinc Rich Foods: Fruits & Vegetables Included
Dr. Rashmi ByakodiMay 13, 2024
Zinc is a crucial micronutrient that plays a vital role in over a hundred enzymatic reactions in the body. Therefore, it is imperative to include zinc-rich foods in your diet. This mineral, along with iron, is necessary in small quantities on a daily basis to support overall health and essential bodily functions.
The advantages of zinc stem from its presence in all bodily tissues. It is essential for promoting healthy cell division and acts as an antioxidant by combatting free radical damage and slowing down the ageing process. Global research has highlighted zinc deficiency as a widespread issue, with insufficient zinc intake being a primary cause.
Around 17.3% of individuals worldwide may not be consuming adequate levels of zinc in their diets. Shockingly, zinc deficiency ranks as the fifth most significant risk factor for disease worldwide. This deficiency can arise when there is a lack of zinc-rich foods in your diet or if there are difficulties in absorbing zinc due to digestive issues or poor gut health.
The encouraging news is that you can enjoy this vital mineral's numerous benefits by incorporating reliable sources of zinc into your daily meals. So, check out the top sources of zinc below:

10 Best Zinc Rich Foods: Fruits and Vegetables
Zinc is found in both animal and plant food sources. But it is best absorbed from animal protein.
Despite the availability of plant-based sources of zinc, their bioavailability is reduced due to their high phytic acid content, which hinders the absorption of this mineral. Studies indicate that individuals who follow a vegetarian or vegan diet may require up to 50% more zinc in their daily diets to meet their needs.
Nevertheless, the inhibitory effects of phytic acid on zinc absorption can be minimized through various methods such as soaking, heating, sprouting, and fermenting. Furthermore, the absorption of zinc can be enhanced by consuming yeast-based breads, sourdough breads, sprouts, and pre-soaked legumes.
Here is a list of the best zinc foods, including fruits and vegetables, that are considered the richest source of this mineral.
(Note: Make sure to consult your doctor before making any major changes in your diet.)
1. Dairy products
Dairy items like milk and cheese contain Zinc. One cup of milk has 1.0 mg of Zinc, which is 9% of the daily value (DV), whereas 100 grams of cheese provides 3.1 gm of Zinc which is 21% of the DV. The Zinc in milk and cheese is bioavailable, which means our body absorbs it quickly.
2. Shellfish
Oysters are high in Zinc and low in calories. That's because a half-dozen oysters contain about 32 milligrams of Zinc, which is about 291 per cent of the daily value for this mineral. Oysters are also rich in vitamin D, copper, and manganese.
Other shellfish, like crabs, contain 7.6 milligrams of zinc per 100 grams. This contributes 69% of the daily value. Mussels and shrimp also have a high Zinc content; they contain 14% of the daily value in 100 grams.
3. Meat
Zinc can be found in large quantities in red meat. One hundred grams of meat contains 4.8 milligrams of Zinc, almost 44 per cent of the daily value. Apart from this, meat provides other essential nutrients such as protein, vitamin B12, and iron. However, meat is also high in fat and cholesterol, so eating too much of it may increase your risk of heart disease and some cancers. It is best to eat meat in moderation.
4. Legumes
These are plant-based foods rich in Zinc. Legumes such as chickpeas, lentils, and beans have abundant Zinc in them. Around 1 cup of legumes contains the following amount of Zinc.
Chickpeas: around 2.5 mg Zinc which is 17% of the DV
Kidney beans: 1.8mg, which is 12% of the DV
Lentils: 2.5 mg of Zinc which is 17% of the DV
Additionally, legumes are low in calories and fat, and high in protein, fibre, and other nutrients. Also, legumes contain phytates, which may inhibit the absorption of Zinc in your body. However, the inhibitory effect of phytates in legumes can be minimised by soaking, sprouting, heating, and fermenting.
5. Seeds
Seeds such as hemp, pumpkin, flax, and sesame are high in Zinc. Here is a list of Zinc content in 30 grams of various seeds.
Hemp seeds provide 5.0 mg of Zinc which is 34% of the daily value
Pumpkin seeds contribute 2.1mg of Zinc which is 14% of the DV
Flaxseeds have 1.2 mg of Zinc which is 8% of the DV
Sesame seeds give 2.2 mg of Zinc which is 14% of the daily value
Apart from being high in Zinc, these seeds have vitamins, minerals, and fibre in ample amounts. They make an excellent addition to your diet if you want to lower your blood pressure and cholesterol.
6. Nuts
Nuts such as peanuts, almonds, and pine nuts contain Zinc. Cashews contain the most Zinc per serving: 30 grams of cashews contain 1.6 mg of Zinc, which is about 11% of your daily value.
Other than Zinc, nuts are also rich in vitamin E, B6, niacin, folate, magnesium, iron, selenium, phosphorus, potassium, copper, healthy unsaturated fats, and fibre. Consuming nuts is beneficial in lowering the risk factors for some diseases like cancer and diabetes.
7. Fruits and vegetables

During pregnancy and breastfeeding, women usually have a higher zinc requirement. But, adults shouldn’t get a maximum of 40 mg of zinc per day. It’s the maximum amount for adults from all sources of zinc, including food and supplements.
Benefits of zinc
Consuming the best zinc foods offers the following benefits:
Fights oxidative stress: Since zinc is an antioxidant, it can combat oxidative stress. Therefore, this mineral can reduce the risk of several diseases. It also helps in fighting off different infections.
Improves eye health: Zinc-enriched foods can activate vitamin A in the body to maintain strong vision. Therefore, the mineral can improve your night eyesight. Moreover, it prevents diminished vision by fighting inflammation and oxidation.
Strengthens the immune system: Zinc-based foods can activate T-cells to support immune function. A high level of zinc in the body can keep the common cold and other illnesses at bay.
Speeds up wound healing: The role of zinc in the human body also includes treating infections. Therefore, it can support faster recovery from wounds.
Balances hormones: Zinc is essential for the synthesis of hormones. It has been demonstrated to naturally raise testosterone levels and sperm quality. It is necessary for women to produce progesterone and oestrogen. The primary hormone responsible for maintaining a normal blood sugar level, insulin, requires zinc in order to function properly. Therefore, consuming the best sources of zinc is quite important for diabetics.
Enhances muscle repair and growth: Zinc is required to keep the skeletal and muscular systems strong since it is essential for cell growth and division. Following a zinc-rich foods chart on a regular basis also facilitates the release of growth hormone, testosterone, and insulin-like growth factor-1. All of these contribute to the development of muscle mass and the maintenance of a healthy metabolism.
Improves cardiovascular health: Adequate levels of zinc in the body are necessary to keep the cells in the cardiovascular system healthy. Moreover, this mineral improves heart health by reducing inflammation and oxidative stress.
Supports nutrient absorption: Zinc is required to use amino acids from food, which also impacts protein synthesis. Additionally, it has a role in the digestive process of carbohydrates, which are among people's main energy sources. For this reason, low energy and adrenal or chronic tiredness may result from not following a zinc-rich diet.
