Short-term cardiovascular responses to ingestion of mineral water in healthy non-obese adults: Impact of mineral components

Monnard, Cathriona Rosemary ; Montani, Jean-Pierre ; Grasser, Erik Konrad

In: Journal of Functional Foods, 2020, vol. 71, p. 104017

Background: The role of mineral components in the hemodynamic response to water drinking is still elusive.Methods: We conducted a randomized crossover study in 16 non-obese, healthy subjects (8 women) to investigate cardiovascular responses to water drinks differing in the mineral content. Continuous measurements included beat- to-beat blood pressure, electrocardiography derived RR-intervals,...

Cardiovascular responses to a glucose drink in young male individuals with overweight/obesity and mild alterations in glucose metabolism, but without impaired glucose tolerance

Monnard, Cathriona R. ; Grasser, Erik Konrad

In: European Journal of Nutrition, 2019, p. -

Little is known about whether mild aberrations in glucose metabolism, which are seen in overweight/obese subjects (OW/OB) without impaired glucose tolerance, affect regulator control elements for blood pressure homeostasis. Methods Hence, we measured in age-matched male subjects with normal weight (n = 16; BMI = 22.4 kg m−2) and OW/OB (n = 11; BMI = 28.6 kg m−2) continuous...

Water ingestion decreases cardiac workload time-dependent in healthy adults with no effect of gender

Monnard, Cathriona R. ; Grasser, Erik Konrad

In: Scientific Reports, 2017, vol. 7, no. 1, p. 7939

Ingestion of water entails a variety of cardiovascular responses. However, the precise effect remains elusive. We aimed to determine in healthy adults the effect of water on cardiac workload and to investigate potential gender differences. We pooled data from two controlled studies where blood pressure (BP) and heart rate (HR) were continuously recorded before and after the ingestion of...

Postprandial hypotension in older adults: Can it be prevented by drinking water before the meal?

Grobéty, Bastien ; Grasser, Erik Konrad ; Yepuri, Gayathri ; Dulloo, Abdul G. ; Montani, Jean-Pierre

In: Clinical Nutrition, 2015, vol. 34, no. 5, p. 885–891

Background & aimsAn important consequence of ageing is a tendency for postprandial blood pressure to decline, which can lead to fainting. As a possible countermeasure, we investigated in healthy older adults the impact of drinking water before a breakfast meal on postprandial cardiovascular and autonomic functions.MethodsAfter a stable cardiovascular baseline recording for at least 20 min,...

Cardiovascular and metabolic responses to tap water ingestion in young humans: does the water temperature matter?

Girona, M. ; Grasser, Erik Konrad ; Dulloo, Abdul G. ; Montani, Jean-Pierre

In: Acta Physiologica, 2014, vol. 211, no. 2, p. 358–370

Aim: Drinking water induces short-term cardiovascular and metabolic changes. These effects are considered to be triggered by gastric distension and osmotic factors, but little is known about the influence of water temperature.Methods: We determined, in a randomized crossover study, the acute cardiovascular and metabolic responses to 500 mL of tap water at 3 °C (cold), 22 °C (room) and...
