Calcium

Consuming bicarbonate-calcium mineral water, low in sodium, can help manage calcium imbalance and support bone health in perimenopausal women.

2023 Metabolites Supplementing Low-Sodium Bicarbonate–Calcic (Lete)® Water: Effects in Women on Bone and Systemic Metabolism Marino C, Pagano I, Castaldo G, Grimaldi M, D’Elia M, Santoro A, et al.

Clinical Study Menopause Mineral Water Osteoporosis

The study involved 120 perimenopausal women who consumed 2 liters of a specific bicarbonate-calcium mineral water (Lete) daily for six months. This water was chosen because it is rich in calcium and bicarbonate but low in sodium. The study aimed to determine the impact of this water on bone health and overall metabolism. The participants’ urine and blood serum were analyzed using NMR-based metabolomic procedures. These analyses were conducted to assess the effects of the water not only on calcium metabolism but also on the broader systemic metabolism.

The findings indicated that the Lete water effectively compensated for calcium dysmetabolism and supported bone health and integrity in perimenopausal women. While the study primarily focused on bone metabolism, it also provided insights into the potential system-wide metabolic effects of this specific type of mineral water. This suggests that such water could be a valuable dietary supplement for addressing calcium-related metabolic issues, particularly in perimenopausal women.

Natural calcium-rich mineral waters offer a bioavailable calcium source, beneficial for bone health, cardiovascular function, weight management, and overall well-being.

2023 Nutrients Exploring the Potential Benefits of Natural Calcium-Rich Mineral Waters for Health and Wellness: A Systematic Review Pop MS, Cheregi DC, Onose G, Munteanu C, Popescu C, Rotariu M, et al.

Systematic Review Bone Health Cardiovascular Disease High Blood Pressure

This systematic review analyzed peer-reviewed articles, clinical trials, and experimental studies from the past decade. It focused on the health benefits of calcium-rich mineral waters, especially for individuals with lactose intolerance or on plant-based diets. The review process assessed the contribution of these waters to daily calcium intake and their bioavailability compared to other calcium sources.

The review found that natural mineral waters high in calcium can significantly enhance calcium intake, with improved absorption rates. These waters show promise in promoting bone health and cardiovascular function, including potential reductions in blood pressure and cardiovascular disease risk. Some evidence suggests benefits in weight management. However, the review highlighted the need for further research on interactions with other dietary components, effects on specific health conditions, and long-term consumption impacts. Despite these gaps, calcium-rich mineral waters are recognized as a valuable dietary calcium source for a diverse population.

Pu-erh tea's ability to lower blood pressure is primarily due to theabrownins and caffeine, which cause vasodilation irrespective of the endothelium.

2019 Frontiers in Pharmacology Pu-Erh Tea Relaxes the Thoracic Aorta of Rats by Reducing Intracellular Calcium Luo Dan, Chen Xuejiao, Zhu Xu, Liu Shuang, Li Jie, Xu Jianping, et al.

Experimental Study High Blood Pressure Pu-Erh Tea

For the research methodology, researchers used pu-erh tea aqueous extract to analyze its effects on rat thoracic aortas previously tightened by Phenylephrine or KCl. They observed the isometric tension and intracellular calcium to gauge the direct effects of the tea. The aqueous tea extract was separated into different fractions using organic solvents to identify the specific active components. They assessed the impact these had on the arteries.

The results demonstrated that the vessels relaxed in response to the pu-erh tea extract, irrespective of whether the endothelium was removed or preincubated with potassium channel blockers. Furthermore, the contractibility of the vessels induced by Phenylephrine or CaCl under different conditions was reduced. There was also a decrease in the KCl-induced increase of intracellular calcium in rat aortic smooth muscle cells. Among the different components, researchers found that the chloroform precipitate of the pu-erh tea extract resulted in the strongest vasodilation. Theabrownins, a major part of this precipitate, and caffeine were identified as the active components causing vasodilation in an endothelium-independent manner.

Consuming a diverse mix of dietary measures enhances iron absorption more effectively than focusing on single nutrients or foods, especially in young women.

2014 Nutrients Dietary Determinants of and Possible Solutions to Iron Deficiency for Young Women Living in Industrialized Countries: A Review Beck K, Conlon C, Kruger R, Coad J

Review Article Iron Deficiency

This review examined dietary factors that contribute to iron deficiency in young women residing in industrialized countries. The study analysed dietary elements such as ascorbic acid and animal protein foods - meat, fish, and poultry - that enhance iron absorption. Conversely, it also explored elements like phytic acid, soy protein, calcium, and polyphenols, which inhibit this process. Furthermore, the research also delved into the complex interactions between these dietary factors, whose consumption effects may cancel each other out.

The study made use of cross-sectional studies to deduce the relationship between diet and iron status. Through these studies, it was discovered that only meat intake consistently resulted in higher serum ferritin concentrations, indicating increased iron stores. In recent studies, the combination and timing of foods consumed were considered, yielding rather mixed results.

The results indicate that while some diet elements such as ascorbic acid and meat enhance iron absorption, their impact may be nullified when consumed alongside inhibitory foods and nutrients. Across different studies, meat intake consistently improved iron status, hinting at its potential role in mitigating iron deficiency. However, the most striking finding is that using a broad selection of dietary measures, rather than focusing on individual nutrients or foods, presents a more effective approach. This suggests dietary diversification could be crucial for preventing and treating iron deficiency, particularly in young women in industrialized countries.

Regular intake of mineral-rich water, high in sodium bicarbonate, potassium, calcium, and magnesium, potentially reduces risk of Metabolic Syndrome and atherosclerotic cardiovascular disease.

2014 International Journal of Endocrinology Relevance of a Hypersaline Sodium-Rich Naturally Sparkling Mineral Water to the Protection against Metabolic Syndrome Induction in Fructose-Fed Sprague-Dawley Rats: A Biochemical, Metabolic, and Redox Approach Pereira CD, Severo M, Araújo JR, Guimarães JT, Pestana D, Santos A, et al.

Animal Study Metabolic Syndrome Mineral Water

Researchers conducted an experiment involving Sprague-Dawley rats, an animal model representing Metabolic Syndrome. For eight weeks, the rats consumed a diet that consisted of 10% fructose. They were also provided with a hypersaline sodium-rich naturally sparkling mineral water to drink. The saline water contained high levels of bicarbonate, potassium, calcium, and magnesium, in comparison to standard tap water, which was used as a control.

The study observed various parameters, from heart rate to plasma triacylglycerols and insulin levels. It also studied hepatic (liver-based) catalase activity, leptin levels, and the weight ratios of different organs to body weight. Moreover, it took into consideration the performance of the liver's antioxidative functions by examining hepatic glutathione peroxidase activity and oxidized glutathione content.

The experiment aimed to determine the effects of the mineral-derived salts in the water on these various aspects of the rat's health, and how they might mitigate the effects of the fructose-enhanced diet that simulated the physiological conditions of Metabolic Syndrome.

Within the results, the scientific team found the intake of mineral-rich water attenuated the increases in heart rate, plasma triacylglycerols, leptin levels, hepatic catalase activity, and organ weight to body weight ratios that were induced by fructose. Furthermore, it prevented the reduction of hepatic glutathione peroxidase activity and oxidized glutathione content. Therefore, the team concluded that the mineral water seemed to have the potential to counteract the effects of the fructose diet, preventing the onset of Metabolic Syndrome. They suggested regular intake of such water could help improve metabolic and redox health.
