Zinc in Nigerian Foods: Why It Matters & Where to Find It

Last Updated on November 15, 2023


Zinc is a crucial mineral for the proper functioning of the human body.

Its importance cannot be overstated as it plays a vital role in numerous physiological processes.

A deficiency in zinc has been linked to various health issues and can have serious consequences.

Zinc is involved in the regulation of the immune system, DNA synthesis, cell division, and growth.

It is also needed for wound healing, taste and smell sensation, and the maintenance of healthy skin and hair.

In fact, it is estimated that zinc is required for the activity of over 300 enzymes in the body.

A lack of zinc in the diet can lead to a weakened immune system, making individuals more susceptible to infections and diseases.

It can also result in delayed wound healing, impaired growth and development, and an increased risk of cognitive disorders.

Furthermore, zinc deficiency has been associated with conditions such as diarrhea, stunted growth in children, poor pregnancy outcomes, and impaired cognitive function in both children and adults.

It can also contribute to age-related macular degeneration, a leading cause of vision loss.

It is therefore crucial to ensure an adequate intake of zinc through a balanced diet.

While zinc can be found in a variety of foods, it is important to know which sources are most abundant.

Including foods such as oysters, red meat, poultry, beans, nuts, and whole grains in your diet can help meet your daily zinc requirements.

In essence, zinc is a vital mineral for the human body, and its deficiency can have significant health implications.

By incorporating zinc-rich foods into your diet, you can ensure optimal health and well-being.

Tips for Maximizing Zinc Absorption

Combining zinc-rich foods with vitamin C

Pairing zinc-rich foods such as oysters, beef, and pumpkin seeds with sources of vitamin C like oranges, strawberries, and bell peppers can enhance zinc absorption.

The presence of vitamin C helps convert zinc into a more absorbable form for the body.

Importance of proper food preparation methods

Opt for cooking methods that preserve the zinc content in foods, such as steaming or baking instead of boiling.

Overcooking or using excessive heat can lead to zinc loss from foods, reducing the available zinc for absorption.

Avoiding foods and beverages that inhibit zinc absorption

Certain foods and beverages contain substances that interfere with zinc absorption, such as phytates found in whole grains and legumes.

While these foods are nutritious, it’s important to balance them with other sources of zinc and not rely solely on them for zinc intake.

Coffee, tea, and alcohol can also hinder zinc absorption, so it’s best to consume them in moderation and separate from zinc-rich meals.

Including animal-based zinc sources

Animal-based foods like meat, poultry, and fish provide a type of zinc that is highly bioavailable and easily absorbed by the body.

Adding these sources to your diet ensures a good supply of absorbable zinc.

Incorporating plant-based zinc sources

Plant-based foods like legumes, whole grains, nuts, and seeds can contribute to overall zinc intake.

However, these foods may also contain compounds like phytates, which can inhibit zinc absorption.

Soaking or sprouting these foods can help reduce phytate levels and improve zinc bioavailability.

Diversifying your food choices

Eating a variety of zinc-rich foods from different food groups ensures that you receive a balanced intake of zinc and other essential nutrients.

Include a mix of animal-based and plant-based sources in your meals to maximize zinc absorption.

Considering zinc supplements

If you have specific dietary restrictions or limited access to certain zinc-rich foods, consulting a healthcare professional about zinc supplements might be beneficial.

Supplements should be taken under guidance, as excessive zinc intake can have adverse effects on health.

Being mindful of zinc interactions with other minerals

Zinc absorption can be influenced by other minerals, such as calcium, iron, and copper.

High doses of these minerals or long-term supplementation can affect zinc absorption, so it’s important to maintain a balanced intake.

Monitoring zinc status

If you suspect a deficiency or are at risk of low zinc levels, consider getting your zinc levels tested by a healthcare professional.

They can guide you on appropriate zinc intake and advise on any necessary dietary adjustments.

Overall healthy diet and lifestyle

Proper nutrition and a balanced lifestyle contribute to optimum absorption and utilization of zinc and other essential nutrients.

Aim for a well-rounded diet, regular exercise, adequate sleep, and stress management to support overall health and well-being.

By following these tips for maximizing zinc absorption, you can optimize your zinc intake and ensure your body receives this essential mineral for its various functions.

Remember, small dietary changes can go a long way in promoting overall health and well-being.


Zinc is an essential nutrient that plays a vital role in the diets of Nigerians. Its importance cannot be overstated.

Zinc is necessary for proper growth, a strong immune system, and the prevention of various diseases.
