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).
Swiss isn't the only type of cheese that contains zinc; cheddar makes the list too. With almost one milligram of zinc per slice, cheddar cheese gets you closer to your total zinc daily value. Add a slice of cheddar to your grass-fed beef burger and you'll meet about 75 percent of your total daily zinc goals.
Sources of Zinc. The richest food sources of zinc include meat, fish, and seafood [3]. Oysters contain more zinc per serving than any other food, but beef contributes 20% of zinc intakes from food in the United States because it is commonly consumed [7]. Eggs and dairy products also contain zinc [3].
Although bananas are rich in carbohydrate, fiber, protein, fat, and vitamins A, C, and B6 they are largely deficient of iron (Fe), iodine, and zinc (Zn).
Food Sources
Meats, poultry, and seafood are rich in zinc. Some plant foods like legumes and whole grains are also good sources of zinc, but they also contain phytates that can bind to the mineral, lowering its absorption.
Egg is rich in phosphorus, calcium, potassium, and contains moderate amounts of sodium (142 mg per 100 g of whole egg) (Table 3). It also contains all essential trace elements including copper, iron, magnesium, manganese, selenium, and zinc (Table 3), with egg yolk being the major contributor to iron and zinc supply.
That makes chicken a good source of the mineral. While the jury is still out on which came first, eggs also contain zinc — about 0.6 mg per large egg, per the USDA — so crack one open today to help optimize your levels of the nutrient.
Yogurt is a rich source of dietary minerals, and the NDBsr26 reports that a 100-g serving of plain low-fat yogurt includes amounts of calcium at 183 mg, magnesium at 17 mg, potassium at 234 mg, phosphorous at 144 mg, and zinc at 0.9 mg (14).
Phytate, which is a natural component of plants, severely decreases intestinal zinc bioavailability and is regarded as the main nutritional inhibitor of zinc absorption.
Feta is also high in phosphorus, iron, manganese, selenium, zinc and potassium. Vitamins: Feta cheese packs in vitamin B6, Vitamin A and phosphorous.
Vegetarians tend to eat higher levels of legumes, soybeans, beans, nuts, and whole-grain food products. While they are healthful food choices, they can impair the body's ability to absorb zinc due to the presence of phytates. These substances bind to zinc, so the body cannot absorb it.
The best way to avoid zinc deficiency for most people is to eat foods that are high in zinc. These include oysters, meat and fish. Smaller amounts of zinc can be found in cereals, legumes, dairy foods and seeds.
Different foods also have different levels of Zn bioavailability. For example, white bread has a Zn content of 10.00 mg·kg−1, a phytic acid content of 99 mg·100 g−1, and phytic acid/Zn molar ratio of 9.8.
A low-fat curd or yoghurt gives us good bacteria for a healthy gut and also provides enough amount of zinc. A cup of curd or yoghurt contains 1.5 mg of zinc.
Chicken is an excellent source of lean protein, which contribute to muscle growth and development. But many of us do not know that it is also rich in zinc content. Eating chicken regularly is good for your bones, heart health and immunity.
When boiled, a single medium sized potato contains about half the daily adult requirement of vitamin C, as well as significant amounts of iron, potassium, fiber and zinc.
Zinc. A serving of peanut butter provides 0.85 mg of zinc. This is 7.7 percent of the recommended daily intake of 11 mg for men, and 10.6 percent of the RDA of 8 mg for women. Zinc is necessary for immunity, protein synthesis, and DNA formation.
Canned Tuna is a Healthy Choice
That's because seafood is rich in important nutrients, such as a vitamins B12 and D, iron, zinc, magnesium, phosphorous, selenium and beneficial omega-3s called EPA and DHA.
Zinc sulfate is the least expensive form, but it is the least easily absorbed and may cause stomach upset. More easily absorbed forms of zinc are zinc picolinate, zinc citrate, zinc acetate, zinc glycerate, and zinc monomethionine.
Bovine milk contains ~3–4 mg/L of zinc, of which 95% is associated with the casein micelles and the rest is associated with citrate molecules in the aqueous phase [49].
