Zinc is an essential trace mineral that plays a significant role in various physiological functions within the body. It is vital for the proper functioning of immune cells, helping to fight off infections and diseases. Zinc also plays a crucial role in skin integrity and structure, promoting healing of wounds and injuries. Additionally, it is involved in the synthesis of proteins and DNA, making it essential for growth and development.
Zinc also contains antioxidant properties that protect cells from oxidative stress and inflammation. It plays a role in hormone production, including insulin, which is important for glucose metabolism. Despite its importance, zinc deficiency affects many individuals and may cause some unpleasant symptoms. Here, let's discuss some of these.
Signs and symptoms of zinc deficiency
In an Instagram video, Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford Universities, says that the "first signs of zinc deficiency are loss of taste and smell or slow wound healing." Other symptoms include:
1. Poor immunity
Low zinc levels can lead to increased susceptibility to infections, colds, and illnesses due to a compromised immune system.
2. Hair loss
Poor zinc levels can affect hair follicles and contribute to thinning or loss of hair.
3. Slow wound healing
"Zinc plays a crucial role in tissue repair and immune signalling, which is why low zinc can take you longer to recover from cuts or infection," said Dr. Sethi.
4. Changes in taste and smell
Since zinc is necessary for the proper functioning of taste and smell sensory cells, its deficiency can reduce the ability to taste or smell, known as hypogeusia or hyposmia.
5. Skin issues
Zinc deficiency can contribute to dermatitis or rashes, particularly around the face and scalp.
6. Digestive issues
Symptoms like loss of appetite, diarrhea, or gastrointestinal issues can also indicate zinc deficiency. However, these can be associated with other health conditions as well.
7. Cognitive dysfunction
Zinc deficiency can affect cognitive functions, leading to problems with memory and attention.
8. Fatigue
Chronic fatigue or lethargy may be experienced due to compromised body functions.
9. Growth and development issues
In children, zinc deficiency can lead to stunted growth and developmental delays.
Tips to boost zinc levels in the body:
"Pumpkin seeds, chickpeas, lentils and cashews are great plant-based sources. If you eat seafood, oysters are the richest natural source," Dr. Sethi said.
To maintain adequate zinc levels, consider the following dietary and lifestyle tips:
1. Eat zinc-rich foods like:
- Meat (beef, pork, and lamb)
- Seafood (especially oysters, which are particularly high in zinc)
- Legumes (chickpeas, lentils, beans)
- Nuts and seeds (pumpkin seeds, sesame seeds, and cashews)
- Whole grains (quinoa, oats, and brown rice)
- Dairy products (milk, cheese, and yogurt)
2. Consider supplementation
If dietary intake is insufficient, consider zinc supplements. However, consult with a healthcare provider before starting any supplement, as excessive zinc can lead to toxicity.
3. Avoid phytates
Some plant-based foods contain phytates, which can inhibit zinc absorption. Soaking, sprouting, or fermenting whole grains and legumes can reduce phytate levels and enhance zinc absorption.
4. Improve gut health
A healthy gut microbiome can improve nutrient absorption, including zinc. Incorporate probiotics and fibre-rich foods for better gut health.
5. Limit alcohol consumption
Excessive alcohol intake can interfere with zinc absorption and increase the risk of deficiency.
6. Monitor medications
Certain medications can interfere with zinc absorption. Check with your doctor if you're on long-term medications to assess their impact on zinc levels.
Follow these measures to maintain healthy zinc levels for optimal health.
