Eine Blutgruppe-Diät

Blut spielt eine der wichtigsten Rollen im menschlichen Körper, denn es transportiert Sauerstoff und Nährstoffe. Blutgruppe ist ein Faktor für unsere Gesundheit und unser Wohlbefinden. Jeder Organismus ist anders und kann andere Ernährungsbedürfnisse haben. Deshalb ist es so schwer, die richtige Ernährung zu wählen, die uns hilft, Gewicht zu verlieren und unseren Körper im richtigen Zustand zu halten.

Diät für Blutgruppe 0

Menschen mit Blutgruppe 0 sind allgemein minded. Es wird ihnen empfohlen, vor allem Fleisch- und Fischprodukte zu konsumieren (schlanke Fische, schlanke Rindfleisch) und Fisch (Schwein, Halibut, Lachs, Mackerel). Menschen mit dieser Blutgruppe sind häufig an Krebs im Dickdarm erkrankt, ermüdet von Schwellungen und Unfällen. Sie sind auch anfällig für Allergie und Asthma. Minder Menschen sollten Milchprodukte, Getreide und Pflanzenprodukte reduzieren.

Diät für Blutgruppe A

Menschen mit Blutgruppe A sind so genannte rollers. Die entsprechenden Produkte in ihrer Ernährung sollten pflanzliche Produkte sein, also vegetarische Produkte. Sie haben eine sehr niedrige Immunität gegen verschiedene Krankheiten, daher benötigen sie ständige Stärkung.

Diät für Blutgruppe B

Anfänger, also Personen mit Blutgruppe B. Sie sollten Fleisch aus Hühner (vor allem Brust) und eines der häufigsten Gemüse oder Tomaten aus ihrem Speiseplan ausschließen. Menschen mit dieser Blutgruppe sind anfällig für Krankheiten wie Verstärkung oder Diabetes.

Die Ernährung für Blutgruppe AB

Alle nicht empfohlenen Produkte in der Ernährung von Blutgruppe A und Blutgruppe B sind auch grundsätzlich verboten in der Diät von Menschen in der Gruppe AB, mit Ausnahme von Tomaten. Es ist eine Diät, in der die Einschränkungen geringst sind, aber die Menschen in die Gruppe AB sollten sie sehr vernünftig nutzen. Genau wie in der Blut Gruppe B, ist es nicht empfehlenswert, Hühnerfleisch zu essen, in diesem Fall können sie ersetzt werden: Lämmchen, Schaf, Hähnchenfleisch und Kaninchen. Die Diät enthält Zitronen, die den Körper reinigen und die Verdauung des Blutes unterstützen.
