High-Bicarbonate Mineral Water Reduces Fasting Blood Lipids
A French pilot study indicates that mineral water high in bicarbonate may lower fasting triglyceride levels. No effect was observed on postprandial lipid values.
A French pilot study has investigated the effect of high-bicarbonate mineral water on blood lipids. Twelve male subjects with moderately elevated cholesterol levels participated in the eight-week intervention study.
Participants consumed 1.25 liters daily of either high-bicarbonate water (4168 mg/l bicarbonate) or low-mineral water. The study found that those drinking the mineral-rich water experienced a 23% reduction in fasting triglycerides. VLDL-triglycerides also decreased by 31%, and VLDL-cholesterol showed a slight reduction.
The researchers noted that high-bicarbonate water consumption led to a decrease in fasting triglycerides. Importantly, despite the high sodium content, there was no observed increase in blood pressure.
No significant changes in blood lipids were observed in the control group or in postprandial measurements. The study authors suggest that the low-calorie nature of the test meal might explain the lack of effect on postprandial lipid values. Further research is indicated to confirm these findings.
