Les eaux embouteillées

Bottled waters, natural mineral water and spring water, meet the specific criteria defined by the regulation. Natural mineral water is characterized by its underground origin, the stability of its composition and its “original purity”. Water is an essential nutrient whose primary function is to hydrate. However, some natural mineral water can contribute to meet the recommended daily allowances (RDA) of minerals such as calcium and magnesium. These minerals from water are well absorbed and as consequence can contribute to meeting until 64 and 44% of daily intake in calcium and magnesium respectively. This recommendation is particularly relevant for children and adolescents, pregnant and lactating women, menopausal women and the elderly whom daily needs are increased. Concerning sulphates, the studies conducted to date do not allow establishing an upper limit of consumption via drinking water as they do not conclude on adverse effects in human being. In conclusion, as part of a balanced diet, natural mineral waters represent a natural source of minerals not negligible all the more they may have beneficial effects on health.
