Manganese plays an important role in the human body, being a cofactor for many enzymes involved in the metabolism of proteins, nucleic acids and fats. Manganese is also important for the proper functioning of the nervous system, the production of connective tissue and bone health.
Manganese requirement in children and adolescents
The manganese intake standards in Poland do not specify the precise demand for manganese, focusing on the sufficient daily intake of manganese (AI), ensuring the proper functioning of the body. For children aged 1-3 years, it is 1.2 mg, in the age group of 4-9 years it increases to 1.5 mg. For girls aged 10-18 years, the sufficient intake of manganese is 1.6 mg, while for boys aged 10-12 years it is 1.9 mg, and then this value increases to 2.2 mg in the age group of 13-18 years.
Manganese requirement in adults
For adult women, the Adequate Daily Intake of Manganese (AI) is 1.8 mg, while for men it is 2.3 mg. For pregnant women, the norm is 2 mg, and for breastfeeding women 2.6 mg.
Occurrence of manganese in food
Manganese is found in many plant foods, such as whole grains (buckwheat), nuts, dry legumes, and vegetables. Tea also provides significant amounts of manganese. Whole grains and legumes are particularly rich in this mineral.
