Africa-Press – Senegal. <\/strong><\/span>Quelle que soit la quantite\u0301 de calories inge\u0301re\u0301es, une alimentation ultra-transforme\u0301e a des effets de\u0301le\u0301te\u0300res notamment sur la fertilite\u0301 et la sante\u0301 cardio-me\u0301tabolique des hommes, conclut une re\u0301cente e\u0301tude clinique. \u00ab La consommation d\u2019aliments ultra-transforme\u0301s en soi, inde\u0301pendamment d\u2019un apport calorique excessif, est ne\u0301faste pour la sante\u0301 humaine \u00bb, montre notamment ce travail publie\u0301 le 28 aou\u0302t dans la revue ame\u0301ricaine Cell Metabolism et coordonne\u0301 par Romain Barre\u0300s, chercheur a\u0300 l\u2019Institut de pharmacologie mole\u0301culaire et cellulaire de Sophia Antipolis (Inserm, CNRS et universite\u0301 Co\u0302te d\u2019Azur), en France.<\/p>\n

A l\u2019e\u0301chelle mondiale, la consommation d\u2019aliments ultra-transforme\u0301s a bondi, et un nombre croissant d\u2019e\u0301tudes e\u0301pide\u0301miologiques a pointe\u0301 sa forte corre\u0301lation avec un risque e\u0301leve\u0301 de maladies chroniques (obe\u0301site\u0301, diabe\u0300te, affections cardiovasculaires…), de cancers, de troubles mentaux, soulignent les auteurs de l\u2019e\u0301tude randomise\u0301e (avec re\u0301partition ale\u0301atoire des participants).<\/p>\n

Jusqu\u2019ici, seules trois e\u0301tudes cliniques, suivant un processus similaire a\u0300 l\u2019e\u0301valuation de me\u0301dicaments, avaient cherche\u0301 a\u0300 e\u0301valuer l\u2019effet direct de cette alimentation sur la sante\u0301 et montre\u0301 qu\u2019elle entrai\u0302nait une surconsommation calorique par rapport a\u0300 une alimentation peu transforme\u0301e.<\/p>\n

Pour cette nouvelle e\u0301tude, 43 hommes de 20 a\u0300 35 ans, en bonne sante\u0301, divise\u0301s en deux groupes, ont suivi deux re\u0301gimes successifs, avec une pause de trois mois entre les deux: l\u2019un riche en aliments ultra-transforme\u0301s, l\u2019autre reposant sur des produits peu ou non transforme\u0301s, pendant trois semaines. Un sous-groupe a rec\u0327u les deux re\u0301gimes, identiques en calories, en quantite\u0301 mode\u0301re\u0301e, ade\u0301quate pour leur a\u0302ge, leur poids et leur niveau d\u2019activite\u0301 physique, l\u2019autre les deux re\u0301gimes en exce\u0300s de calories de 500 kcal quotidiennes. Des prises de sang, analyses de sperme et autres mesures (poids, choleste\u0301rol…) e\u0301taient re\u0301gulie\u0300res.<\/p>\n

Prise de poids<\/b><\/p>\n

Dans ses re\u0301sultats notables, l\u2019e\u0301tude e\u0301tablit un impact sur la fertilite\u0301 du re\u0301gime ultra-transforme\u0301: chute de l\u2019hormone stimulant la production de spermatozoi\u0308des (FSH) et de la testoste\u0301rone chez la plupart des participants, baisse du nombre de spermatozoi\u0308des mobiles. Des polluants pre\u0301sents dans les aliments ultra-transforme\u0301s, aux effets de perturbateurs endocriniens, pourraient notamment jouer un ro\u0302le, jugent les chercheurs.<\/p>\n

Autre enseignement: en trois semaines, \u00ab la consommation d\u2019aliments ultra-transforme\u0301s par rapport a\u0300 celle d\u2019aliments non transforme\u0301s a entrai\u0302ne\u0301 une prise de poids de 1,4 kg et 1,3 kg respectivement dans les groupes ayant un apport calorique ade\u0301quat et excessif \u00bb, principalement en masse graisseuse. Les individus ayant re\u0301duit le niveau de transformation de leur alimentation ont notamment perdu du poids.<\/p>\n

Les chercheurs reconnaissent des limites a\u0300 leur e\u0301tude: les participants n\u2019ayant pas e\u0301te\u0301 hospitalise\u0301s, la mesure de leur apport e\u0301nerge\u0301tique reposait sur leurs de\u0301clarations, et la dure\u0301e courte des re\u0301gimes, trois semaines, peut \u00ab avoir induit des re\u0301ponses aigue\u0308s \u00bb, dont un niveau inflammatoire qui aurait pu se stabiliser avec le temps.<\/p>\n
