Cette affirmation provient du fait que la cuisson des v\u00e9g\u00e9taux (dont les tomates) affaiblit la matrice fibreuse, augmentant ainsi la biodisponibilit\u00e9 des carot\u00e9no\u00efdes. <\/span>Par ailleurs, l\u2019ingestion simultan\u00e9<\/span>e<\/span> de lipides (ex<\/span>. <\/span>frites de patate douce<\/span> ou <\/span>salade de carottes <\/span>avec de l\u2019huile d\u2019olive<\/span>) augmente la <\/span>biodisponibilit\u00e9<\/span> des carot\u00e9no\u00efdes.\u00a0<\/span><\/span>\u00a0<\/span><\/p>[\/et_pb_text][\/et_pb_column][et_pb_column _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb type=\u00a0\u00bb1_3″ theme_builder_area=\u00a0\u00bbpost_content\u00a0\u00bb][et_pb_image src=\u00a0\u00bbhttps:\/\/epithelia.ca\/wp-content\/uploads\/2024\/10\/Capture-decran-le-2024-10-05-a-19.17.13.png\u00a0\u00bb _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb theme_builder_area=\u00a0\u00bbpost_content\u00a0\u00bb alt=\u00a0\u00bbTomate crue ou cuite ?\u00a0\u00bb title_text=\u00a0\u00bbTomate crue ou cuite ?\u00a0\u00bb hover_enabled=\u00a0\u00bb0″ sticky_enabled=\u00a0\u00bb0″][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb theme_builder_area=\u00a0\u00bbpost_content\u00a0\u00bb][et_pb_column _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb type=\u00a0\u00bb4_4″ theme_builder_area=\u00a0\u00bbpost_content\u00a0\u00bb][et_pb_text _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb theme_builder_area=\u00a0\u00bbpost_content\u00a0\u00bb hover_enabled=\u00a0\u00bb0″ sticky_enabled=\u00a0\u00bb0″]

Bien que cela puisse para\u00eetre bizarre, cela s\u2019av\u00e8re une r\u00e9alit\u00e9! Les carot\u00e9no\u00efdes ont une toxicit\u00e9 dite esth\u00e9tique. En revanche, le seuil de toxicit\u00e9 est rarement atteint si on adopte un r\u00e9gime alimentaire diversifi\u00e9.
