Avez-vous d\u00e9j\u00e0 croqu\u00e9 le p\u00e9pin d’un raisin\u00a0?<\/strong><\/p>\n

Il y a de grande chance que oui… et vous vous rappelez aujourd’hui encore ce go\u00fbt amer et d\u00e9sagr\u00e9able.<\/p>\n

Mais vous \u00eates-vous d\u00e9j\u00e0 demand\u00e9 pourquoi les p\u00e9pins de raisin ont un go\u00fbt si horrible\u00a0?<\/p>\n

Une histoire d’\u00e9volution<\/h2>\n

La th\u00e9orie de l’\u00e9volution nous apporte un \u00e9l\u00e9ment de r\u00e9ponse\u00a0: les p\u00e9pins de raisin ne sont pas destin\u00e9s \u00e0 \u00eatre mang\u00e9s\/dig\u00e9r\u00e9s\/d\u00e9truits, contrairement au fruit.<\/strong><\/p>\n

Pourquoi ? Parce que le p\u00e9pin de raisin contient le patrimoine g\u00e9n\u00e9tique de la plante.<\/p>\n

L’id\u00e9e est la suivante\u00a0: la vigne fabrique des fruits les plus d\u00e9licieux possibles, afin que les animaux qui passent \u00e0 proximit\u00e9 les consomment. Les p\u00e9pins, cach\u00e9s au c\u0153ur des grains de raisins, sont ing\u00e9r\u00e9s par la m\u00eame occasion, puis \u00ab\u00a0expuls\u00e9s\u00a0\u00bb car non dig\u00e9r\u00e9s. Avec un peu de chance, le p\u00e9pin germera et un nouveau pied de vigne verra le jour.<\/p>\n

C’est donc une sorte de deal entre l’animal et la plante<\/strong> : l’animal trouve de l’\u00e9nergie dans le fruit, et en retour la plante obtient un moyen de se reproduire.<\/p>\n

Mais si l’animal essaye de rompre le deal en d\u00e9truisant le p\u00e9pin, \u00e7a ne marche plus pour la plante : le p\u00e9pin est donc prot\u00e9g\u00e9<\/strong> (go\u00fbt d\u00e9sagr\u00e9able) et si l’animal croque dedans… il s’en rappelle et ne recommence pas\u00a0\ud83d\ude42<\/p>\n

\"\"<\/a><\/p>\n

Les c\u00e9r\u00e9ales ont \u00e9volu\u00e9 de mani\u00e8re similaire<\/h2>\n

Savez-vous ce que sont les graines de bl\u00e9 pour la plante \u00ab\u00a0bl\u00e9\u00a0\u00bb\u00a0?<\/p>\n

Vous l’avez devin\u00e9\u00a0: les graines du bl\u00e9 jouent un r\u00f4le similaire \u00e0 celui des p\u00e9pins de raisin pour la plante \u00ab\u00a0raisin\u00a0\u00bb<\/strong>. Il s’agit d’un petit emballage destin\u00e9 \u00e0 prot\u00e9ger du mat\u00e9riel g\u00e9n\u00e9tique qui servira \u00e0 assurer la survie de l’esp\u00e8ce.<\/p>\n

Et la nature n’a pas \u00e9t\u00e9 tr\u00e8s inventive puisqu’elle a pr\u00e9vu des m\u00e9canismes de d\u00e9fense similaire pour prot\u00e9ger les c\u00e9r\u00e9ales<\/strong>.<\/p>\n

Mangeriez-vous un bol de p\u00e9pins de raisin au petit-d\u00e9jeuner ?<\/h2>\n

Vous mangeriez bien un bol de c\u00e9r\u00e9ales pourtant \ud83d\ude09<\/p>\n

Si les c\u00e9r\u00e9ales n’ont pas un go\u00fbt aussi d\u00e9sagr\u00e9able que celui des p\u00e9pins de raisin, le concept de prot\u00e9ger l’esp\u00e8ce en prot\u00e9geant la graine est le m\u00eame\u00a0: les c\u00e9r\u00e9ales<\/strong> (comme les l\u00e9gumineuses \u00e0 vrai dire) contiennent des compos\u00e9s chimiques destin\u00e9s \u00e0 emp\u00eacher la consommation animale<\/strong> (et humaine).<\/p>\n

Pour aller plus loin, retrouvez ici un article expliquant les m\u00e9canismes de d\u00e9fense des c\u00e9r\u00e9ales<\/a>, et en quoi la consommation des c\u00e9r\u00e9ales n’est pas une bonne chose pour l’esp\u00e8ce humaine.<\/p>\n
