HUMAN NUTRITION

Detailed explanation-1: -The digestion of fats begins in the first section of the small intestine, the duodenum. Globules of fat in the acidic chyme coming from the stomach are broken up by intestinal movements, and the smaller droplets become coated with bile molecules that are delivered to the duodenum through the common bile duct.

Detailed explanation-2: -The body begins breaking down fat in the mouth, using enzymes in saliva . Chewing increases the surface area of foods, allowing the enzymes to break down food more effectively. The most important chemicals that help with fat digestion in the mouth are lingual lipase and phospholipids, which turn fats into small drops.

Detailed explanation-3: -After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas. The absorption of vitamins, minerals, and other nutrients begins in the duodenum.

Detailed explanation-4: -Although the jejunum is the main intestinal compartment responsible for lipid digestion and absorption, most of the studies assessing the impact of dietary lipids on the intestinal microbiota have been performed in the ileum, colon and faeces.
