When the human body ingests vitamin C, it will first be absorbed by the small intestine, so the concentration of vitamin C in the small intestine is the highest.

The histostructural characteristics of the small intestine create good conditions for the absorption of the small intestine, and the physiological functions of the small intestine are manifested in the motility, secretion, digestion and absorption of the hairy small intestine, and are closely related to drug metabolism.

For example, various forms of movement of small intestinal smooth muscle can complete the mechanical digestion of chyme such as grinding, mixing, stirring, etc., the small intestinal fluid secreted by the small intestinal gland and bile and pancreatic juice in the small intestine together to complete the chemical digestion of chyme, and there are many endocrine cells scattered in the small intestinal mucosa, which can secrete a variety of digestive tract hormones, such as secretin, cholecystokinin, gastric inhibitory peptide and motilin, etc., which have an important regulatory effect on gastrointestinal motility and secretion.

Due to the chemical digestion of pancreatic juice, small intestine fluid and bile and the mechanical digestion of small intestine movement, the digestion process of food is basically completed in the small intestine, and most of the digested nutrients are absorbed in the small intestine, so the small intestine is the most important part of digestion and absorption.

When a person eats vitamin C, the pituitary gland and kidneys have the highest concentration of vitamin C, followed by the eyeball, brain, liver, spleen and other parts.

Similarly, lamb liver and beef liver cannot be eaten together.

Milk + vitamin C

It has a certain acidity and strong reducing properties, and is easily oxidized. Milk is rich in vitamin B2 with a certain oxidizing property, and vitamin C is easily oxidized by vitamin B2 when taken at the same time, and vitamin B2 is reduced, both of which lose their effectiveness at the same time, and cannot achieve the purpose of vitamin supplementation.

Shellfish products.

Shellfish contain a lot of arsenide, but because these arsenides are in the form of 5-valent, they will not have any effect on the human body.
