Fatty liver is a duck or goose is known as Foie Gras. But humans get it too. Here it’s known as fatty liver disease or non alcoholic steatohepatitis (NASH). How do we get NASH? It all comes down to what we eat.
Foods are broken down in the stomach and small intestine for easier absorption. Proteins are broken into amino acids. Fats are broken into fatty acids. Carbohydrates, composed of chains of sugars, are broken into smaller sugars. Carbohydrates raise blood glucose where proteins and fats do not. Some carbohydrates, particularly sugars and refined grains raise blood glucose effectively, which stimulates insulin release.
Dietary protein also raises insulin levels but not blood glucose by simultaneously raises other hormones such as glucagon and incretins. Dietary fats raise both blood glucose and insulin levels minimally. Absorption of fatty acids differs markedly from both amino acids and sugars. Amino acids and sugars are delivered through the intestinal bloodstream, known as the portal circulation, to the liver for processing. The liver requires insulin signaling for proper management of these incoming nutrients.
