Wissenschaftliche Erkenntnisse über Ernährung

Obwohl ketogene und kohlenhydratarme Diäten von einigen Gesundheitsexperten als umstritten angesehen werden, gibt es inzwischen hochwertige Belege, die ihre routinemäßige Anwendung zur Gewichtsabnahme und bei bestimmten Stoffwechselerkrankungen wie Typ-2-Diabetes, Bluthochdruck und einigen Formen von Dyslipidämie unterstützen. Es gibt auch vorläufige Beweise für seine Verwendung bei anderen Erkrankungen.

Es gibt wissenschaftlich fundierte Beweise dafür, dass natürlich vorkommende gesättigte Fette nicht gesundheitsschädlich sind; Warnungen über die gesundheitlichen Gefahren von rotem Fleisch basieren auf schwachen Beweisen; fettarme Diäten scheinen keine besonderen Vorteile für die Gesundheit oder das Gewicht zu haben, die über die einer kohlenhydratarmen Ernährung hinausgehen.

Hier sind einige prominente wissenschaftliche Studien, die viele Mythen, die wir über Ernährung haben, unterstützen und klären:
