The importance of zinc for health
Zinc is one of the most abundant trace elements in the human body. It is found mainly in the muscles (60 to 65%), bones (20%), liver and skin.
It is essential for the proper functioning of the immune system, for the effective healing of wounds, and for keeping skin, hair and nails in perfect health. Even in small quantities, it plays a vital role in metabolism, the process of cell division and the creation of proteins.
The health benefits of zinc
- Boosts the immune system: zinc plays a key role in boosting the immune system, stimulating the production of white blood cells and helping to fight infections. It can even reduce the duration of colds if consumed as soon as the first signs appear.
- Helps healing: it is a powerful antioxidant, helping to combat cell ageing and acting on skin problems (acne, stretch marks, etc.) by promoting healing. Zinc supports skin regeneration and is commonly used to treat burns, cuts and other injuries.
- Ideal for skin, nails and hair: it promotes healthy skin by reducing inflammation and regulating sebum secretion, helping to prevent acne. It is also vital for strong hair and nails, acting on keratin synthesis to help increase hair mass.
- During pregnancy: zinc plays a crucial role in the healthy development of the foetus. Not only does it contribute to cell growth and development, but it is also involved in DNA synthesis and the optimal functioning of the immune system. Adequate zinc intake during pregnancy is essential to minimise the risk of complications and ensure the well-being of both mother and child.
- Regulation of hormonal activity: it has an impact on hormonal balance, particularly with regard to insulin, the hormone responsible for regulating blood sugar levels. By influencing its activity, zinc helps to maintain a balanced metabolism, preventing blood sugar fluctuations that can lead to diabetes or insulin resistance.
How can I tell if I'm zinc deficient?
Signs of zinc deficiency can include hair loss, skin problems, increased susceptibility to infections, night vision problems and difficulties with wound healing. If you suspect a deficiency, it is advisable to consult a healthcare professional for a proper diagnosis and treatment.
What are the best food sources of zinc?
Food sources such as red meat, seafood (particularly oysters), legumes, nuts and seeds are excellent for achieving the recommended daily intake of zinc. A varied diet is generally enough to meet the body's needs.
Zinc supplements, combined with a healthy and varied diet, may be useful for certain populations, such as vegetarians, senior citizens or people with specific medical conditions, provided that the recommended doses are respected to avoid over-consumption.
Warnings and side effects of zinc
High doses, or even overdoses, of zinc can sometimes cause side effects such as abdominal pain, nausea, headaches, etc.
Not recommended for pregnant or breast-feeding women, or for people undergoing specific medical treatment, without prior medical advice.
About zinc
Used since ancient times for its medicinal virtues and in the creation of alloys such as brass, zinc's role in human well-being has only recently been recognised, highlighting the importance of nutritional research.
