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,...

Cardio- and cerebrovascular responses to the energy drink Red Bull in young adults: a randomized cross-over study

Grasser, Erik K. ; Yepuri, Gayathri ; Dulloo, Abdul G. ; Montani, Jean-Pierre

In: European Journal of Nutrition, 2014, p. 1–11

Purpose: Energy drinks are beverages containing vasoactive metabolites, usually a combination of caffeine, taurine, glucuronolactone and sugars. There are concerns about the safety of energy drinks with some countries banning their sales. We determined the acute effects of a popular energy drink, Red Bull, on cardiovascular and hemodynamic variables, cerebrovascular parameters and microvascular...

Hepatic mitochondrial energetics during catch-Up fat with high-Fat diets rich in lard or safflower oil

Crescenzo, Raffaella ; Bianco, Francesca ; Falcone, Italia ; Tsalouhidou, Sofia ; Yepuri, Gayathri ; Mougios, Vassilis ; Dulloo, Abdul G. ; Liverini, Giovanna ; Iossa, Susanna

In: Obesity, 2011, p. -

We have investigated whether altered hepatic mitochondrial energetics could explain the differential effects of high-fat diets with low or high ω6 polyunsaturated fatty acid content (lard vs. safflower oil) on the efficiency of body fat recovery (catch-up fat) during refeeding after caloric restriction. After 2 weeks of caloric restriction, rats were isocalorically refed with a low-fat diet (LF)...

Dietary modulation of body composition and insulin sensitivity during catch-up growth in rats: effects of oils rich in n-6 or n-3 PUFA

Yepuri, Gayathri ; Marcelino, Helena ; Shahkhalili, Yasaman ; Aprikian, Olivier ; Macé, Katherine ; Seydoux, Josiane ; Miles, Jennifer L. ; Montani, Jean-Pierre ; Dulloo, Abdul G.

In: British Journal of Nutrition, 2011, vol. 105, p. 1750-1763

The present study investigates whether excessive fat accumulation and hyperinsulinaemia during catch-up growth on high-fat diets are altered by n-6 and n-3 PUFA derived from oils rich in either linoleic acid (LA), α-linolenic acid (ALA), arachidonic acid (AA) or DHA. It has been shown that, compared with food-restricted rats refed a high-fat (lard) diet low in PUFA, those refed...
