Digestion And Absorption

Succus entericus is secreted by the intestinal glands of the Crypts of Lieberkuhn.

Succus entericus or intestinal juice is secreted by intestinal glands. It contains enzymes such as maltase, sucrose, lactase, enterokinase, etc. Intestinal glands are formed by the surface epithelium of the small intestine. These are two types of crypts of Lieberkuhn and Brunner's glands. Succus entericus is majorly produced by the crypts of Lieberkuhn as these glands occur throughout the small intestine. They secrete digestive enzymes and mucus. Whereas, Brunner's glands are found only in the duodenum. They secrete mucus and a small number of enzymes. The mucus helps in protecting the duodenal wall from getting digested. 

A balanced dietdoes not include carbohydrates and fats 

• Sugar: A balanced diet always limits the level of sugars that are found in beverages, candies and sweets etc. There can be problems such as weight gain, dental problems and chronic disease like diabetes.
• Saturated and trans fats: Saturated fats includes fatty meat, butter and many processed fats. Trans fats are the ones that are fried and have a lower level of good cholesterol level. All of this can lead to diseases and health problems.
• Processed food: balanced diet includes unprocessed food rather than refined food. The processed food has a higher level of unhealthy fats, high levels of salts etc.

An individual dietary needs can vary based on age, sex, activity level, and health conditions.
