Hypercholesterolemia
Conditions
Brief summary
The goal of this study is to evaluate the hypolipidemic effect (reduction of Low Density Lipoprotein Cholesterol "LDL-C" values) of calcium-bicarbonate mineral water "Lete" (alkaline water, high in bicarbonate and calcium ions and low in sodium) compared to control oligomineral water "Sorgesana" on healthy volunteers
Detailed description
This sponsored, monocentric and interventional study will consist of a screening visit, a baseline visit, a phone contact one month after the baseline visit and two follow-up visits in person, two and four months after the baseline visit. After signing the informed consent and verifying the eligibility criteria, 160 healthy subjects will be randomized in a 1:1 double-blind ratio to one of two study arms. During the baseline visit, informations regarding the patient's medical history, demographic, anthropometric and blood pressure data and concomitant medications will be collected and the patient will be asked to complete a questionnaire related to physical activity assessment and to undergo an evaluation test for proper nutrition. Then, a blood sample will be taken for hematochemical analysis to evaluate the study endpoints. Finally, during the two follow-up visits, treatment adherence will be assessed, a blood sample will be taken for hematochemical analysis and the patient will be asked to complete the questionnaire and to undergo the evaluation test for proper nutrition. Additionally, at the second follow-up visit, anthropometric and blood pressure data will be collected
