BACKGROUND Dietary acid charge enhances bone loss. Bicarbonate or alkali diet decreases bone resorption in humans. We compared the effect of an alkaline mineral water, rich in bicarbonate, with that of an acid one, rich in calcium only, on bone markers, in young women with a normal calcium intake. METHODS This study compared water A (per litre: 520 mg Ca, 291 mg HCO(3)(-), 1160 mg SO(4)(-), P...

INTRODUCTION A sufficient intake of calcium enables correct bone mineralization. The bioavailability of calcium in water is similar to that in milk. OBJECTIVE To determine the concentration of calcium in public drinking water and bottled mineral water. METHODS We used ion chromatography to analyse the calcium concentrations of public drinking waters in a representative sample of 108 Spanish...

INTRODUCTION An appropriate magnesium intake has proved to have beneficial effects on bone health, reduce insulin resistance and prevent atherosclerosis. OBJECTIVE To determine the concentration of magnesium in drinking water and bottled mineral water in Spain and assess its daily contribution to dietary recommendations. METHODS We used ion chromatography to analyse the magnesium concentrat...

Catechol-O-methyltransferase (COMT) is a magnesium-dependent, catecholamine-metabolizing enzyme, whose impaired activity has been positively associated with cardiovascular diseases, particularly hypertension. Consumption of some natural mineral-rich waters has been shown to exert protective effects on cardiovascular risk factors, eg. by decreasing arterial blood pressure and blood lipids. Howev...

Copper effects on human health represent a relevant issue in modern nutrition. One of the difficulties in assessing the early, acute effects of copper ingested via drinking water is that the taste of copper may influence the response and the capacity to taste copper in different waters is unknown. The purpose of the study was to determine the taste threshold of copper in different types of wate...

Water is arguably the most essential nutrient for terrestrial animals. Thus, it isn’t surprising that water quality plays a significant role in animal health and productivity. Never in great supply, high quality water for livestock and wildlife is becoming scarcer as the result of competition by mineral development and urbanization. While animals can, and often do, subsist upon less-than-perfec...

The different types of mineral industries wastes are characterized. Total tonnage in the world of finely ground wastes from i.a. flotation and leaching operations amounts to around 1 500 million tons per annum. The major environmental problems arise from slowly settling fine particles, dissolved metal ions and chemicals retained in the effluent. The paper discusses the toxic effects of dissolve...

Consuming a high-fructose diet induces metabolic syndrome (MS)-like features, including endothelial dysfunction. Erectile dysfunction is an early manifestation of endothelial dysfunction and systemic vascular disease. Because mineral deficiency intensifies the deleterious effects of fructose consumption and mineral ingestion is protective against MS, we aimed to characterize the effects of 8 we...
