L’essai clinique montre pourquoi les boissons énergétiques sont mauvaises pour le cœur

Les boissons énergétiques sont populaires, surtout chez les adolescents et les jeunes adultes. Mais un essai clinique rapporte que les boissons énergétiques ont causé des perturbations aux rythmes cardiaques et à la pression artérielle des bénévoles.

Comment les boissons énergisantes affectent-elles le cœur?

Boissons énergétiques sont le deuxième complément alimentaire le plus populaire de choix pour les adolescents et les jeunes adultes aux États-Unis, selon le Centre national de la santé complémentaire et intégrative (NCCIH).

Emballés avec de la caféine et d’autres ingrédients, tels que le guarana, la taurine, le ginsenget les vitamines B, ces boissons promettent de stimuler la concentration, d’améliorer les performances physiques et de réduire la fatigue.

Un article récent de la Revue américaine de médecine préventive augmente la popularité des boissons énergétiques en chiffres.

Le pourcentage de jeunes de 12 à 19 ans consommant des boissons énergisantes aux États-Unis est passé de 0,2 en 2003 à 1,4 en 2016. La plus forte augmentation a été chez les jeunes adultes âgés de 20 à 39 ans, passant de 0,5 à 5,5 en cette période, tandis que le chiffre est passé de 0 à 1,2 chez les adultes de 40 à 59 ans, selon les auteurs de l’étude.

Pourtant, les preuves de montage dépeint les boissons énergétiques sous une lumière différente. «Consommer des boissons énergétiques soulève des préoccupations importantes en matière de sécurité», selon le NCCIH, avec deux fois plus de visites de service d’urgence liées aux boissons énergétiques enregistrées en 2011 que dans 2007.

Dans le plus grand essai clinique randomisé et contrôlé sur le sujet à ce jour, des chercheurs de l’Université du Pacifique à Stockton, CA, ainsi que des collaborateurs d’autres institutions, identifient comment la consommation de boisson énergétique affecte le cœur.
