Canard carolin femelle et ses petits, comté d’Arapahoe, Colorado ...                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         Cette Cette sympathique famille de canard appartient à l’espèce “carolin”, baptisée ainsi en référence à l’État américain où elle a été pour la première fois observée.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      Nos amis sont donc bien originaires d’Amérique du Nord, même si parfois on peut les trouver dans quelques parcs animaliers d’Europe.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               Le mâle est particulièrement reconnaissable à son magnifique plumage coloré qu’il revêt lors de la période des amours.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 L’autre particularité de cette espèce est que, contrairement aux autres canards, ils nichent dans les arbres. C’est grâce à leurs pieds munis de griffes qu’ils peuvent accomplir cette prouesse.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           Les petits naissent ainsi en hauteur et doivent, alors qu’ils ne sont âgés que de deux jours, sauter du nid pour gagner la mare. Cela peut paraître effrayant mais heureusement peu de poussins se blessent pendant cet exercice.

Découvrez ces conseils de "Grands Mères",  sur les familles d’aliments bénéfiques pour prévenir au mieux les éventuelles maladies des yeux et garder toute sa vie une excellente vue.

                                                                                                                                                                                                                                                                                                                   * Les poissons gras  :

                                                                                                                                                                                                                                                                                                                                                           Riches en omégas 3, les poissons gras comme le thon, le hareng ou la sardine (à la vapeur ou grillé) permettent de mieux entretenir les membranes cellulaires des cellules nerveuses, dont celles de la rétine et de prévenir l’apparition de maladies oculaires liées à l’âge.

                                                                                                                                                                                                                                                                                                                                                             * * Clémentines, oranges et mandarines  :

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       Comme tous les agrumes, ces fruits que l’on trouve presque toute l’année sont riches en vitamines C. Des antioxydants très utiles et connus pour protéger la cornée et le cristallin de l’oeil, ainsi que pour aider à prévenir la cataracte, une maladie qui apparait avec l’âge et provoque notamment des éblouissements la nuit.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                

* Les carottes  :

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     A l’image de beaucoup d’autres fruits orange et jaunes, la carotte est pleine de bêtacarotène, un antioxydant précurseur de la vitamine A, et de pigments protégeant la rétine, notamment contre l’apparition de la cataracte. Attention aux carences qui peuvent provoquer une baisse de l’acuité visuelle. A cuisiner cuit ?plusieurs fois par semaine.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    

* Les myrtilles  :                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     

Réputées améliorer la vision nocturne et testées à cet effet pendant la Seconde Guerre mondiale par les pilotes de la Royal Air Force, les myrtilles associent vitamine C et anthocyanidines, des composants qui boostent l’acuité visuelle et qui ont un effet bénéfique sur la fatigue oculaire.

* L’oeuf  :                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

Grâce à ses nombreux antioxydants, dont la vitamine A, essentielle pour bien voir la nuit, cet aliment est réputé pour ses vertus protectrices, notamment contre la dégénérescence maculaire liée à l’âge (DMLA), une maladie de la rétine qui apparait avec le vieillissement.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         

* Le brocoli  :

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                Grâce à sa quantité non négligeable de délutéine et de zéaxanthine, des pigments indispensables à la bonne santé des yeux,cet ingrédient à manger en salade, cuit ou en épis, protège contre la DMLA. Consommer 5 à 6g par jour de ces pigments protègerait même de façon optimale contre la cataracte.
