Es un estudio epidemiológico, pero es una hipótesis que debería investigarse experimentalmente. A las industria médica no le interesa mucho obviamente, pero un consumo de agua bajo se asocia a un 50% más de cardiopatías.

Water, Other Fluids, and Fatal Coronary Heart Disease

Abstract

Whole blood viscosity, plasma viscosity, hematocrit, and fibrinogen are considered independent risk factors for coronary heart disease and can be elevated by dehydration. The associations between fatal coronary heart disease and intake of water and fluids other than water were examined among the 8,280 male and 12,017 female participants aged 38–100 years who were without heart disease, stroke, or diabetes at baseline in 1976 in the Adventist Health Study, a prospective cohort study. A total of 246 fatal coronary heart disease events occurred during the 6-year follow-up. High daily intakes of water (five or more glasses) compared with low (two or fewer glasses) were associated with a relative risk in men of 0.46 (95% confidence interval (CI): 0.28, 0.75; p trend = 0.001) and, in women, of 0.59 (95% CI: 0.36, 0.97). A high versus low intake of fluids other than water was associated with a relative risk of 2.47 (95% CI: 1.04, 5.88) in women and of 1.46 (95% CI: 0.7, 3.03) in men. All associations remained virtually unchanged in multivariate analysis adjusting for age, smoking, hypertension, body mass index, education, and (in women only) hormone replacement therapy. Fluid intake as a putative coronary heart disease risk factor may deserve further consideration in other populations or using other study designs.

De nuevo intrigante: el consumo de agua asociado a menores tasas de diabetes tipo II

Higher plain water intake is associated with lower type 2 diabetes risk: A cross-sectional study in humans

The aim of this study was to investigate the relationship between plain water intake and type 2 diabetes (T2D) risk. It was hypothesized that higher plain water intake would be associated with a lower T2D risk score. 138 adults from Southwest and Southeast England answered a cross-sectional online survey assessing T2D risk (using the Diabetes UK risk assessment), physical activity (using the short International Physical Activity Questionnaire), and consumption of fruits, vegetables and beverages (using an adapted version of the Cambridge European Prospective Investigation into Cancer and Nutrition Food Frequency Questionnaire). There was a trend for differences in mean plain water intake between those stratified as having low, increased, moderate or high risk of T2D but these did not achieve significance (P=0°084). However, plain water intake was significantly negatively correlated with T2D risk score (τ=−0°180, P=0°005), and for every 240mL cup of water consumed per day, T2D risk score was reduced by 0°72 points (range 0–47) (B=−0°003, 95% CI=−0°006, −0°001, P=0°014). The current study has provided preliminary results which are supported by theory; mechanisms need to be explored further to determine the true effect of plain water intake on disease risk. As increasing plain water intake is a simple and cost effective dietary modification, its impact on T2D risk is important to investigate further in a randomized controlled trial. Overall, this study found that plain water intake had a significant negative correlation with T2D risk score and regression analysis suggested that water may have a role in reducing T2D risk.
