glucostatic

Hunger drive is controlled by hypothalamus. Glucostatic thery of hunger suggests that an increase in blood glucose level increases the activity of the safety center and decreases the activity of hunger center. Low blood glucose has the opposite effects. Aminoacid levels and lipid levels have also been suggested to influence hunger and satiety. The hepotostatic theory of hunger control argues for a role of liver as an important sensor and modulator of the body energy stores. digestion

The Slow Food Movement’s Health Impact

The slow food movement is said to have originated with Italian Carlo Perrini, in part through his indignation at a McDonald’s opening in the vicinity of the Spanish Steps in Rome. From Perrrinis’ frustration with the intrusion of the American fast-food style of dining a worldwide movement has emerged. The hallmark of slow food is, as its name implies, taking the time to savor and enjoy a meal at a leisurely pace. Other elements of the slow food diet include buying and eating locally produced food, eating organic food and cooking home meals based on traditional recipes.

The slow food movement has certainly caught on, due in part to people being tired of the fast-food dining style and also out of a passion to eat healthier food. But does the slow food movement make for better health? The general outlook of the slow food movement on changing the eating habits of people does seem to assure that eating meals the slow food way will have a positive impact on your life. One major health benefit of the slow food is eating your meals slowly. Most research on the topic indicates that eating at an unhurried pace will help you promote a calm that in turn helps aid digestion.

Another health benefit of the slow food movement is its interest in getting people to buy locally grown fresh foods with minimal packaging and processing. Again, these are all ways of approaching eating that contribute to a more healthy lifestyle by reduced the amount of fat, preservatives and other chemical additives in your food. In addition, the slow food movement encourages people to buy organic produce as much as possible, thereby greatly reducing or eliminating the amount of pesticides in your diet. It seems clear that the slow food movement is designed to make you eat healthier and live a healthier lifestyle. by digestive phsiology

What is the digestive system ?

The digestive system is a technological marvel of the human body. It helps us to chew digest, extract nutriments and get rid of that which we don’t need. In order to understand the digestive system it is important to know it various organs. The digestive system includes the digestive tract, a tube extending from the mouth to the anus, as well as a host of other organs.

The first area of the digestive system and where the journey of all our food begins is the mouth or oral cavity. The mouth includes the lips, cheeks, teeth and palate and it also contains the tongue. The salivary glands and tonsils complete the mouth area. is surrounded by the lips, cheeks, teeth, and palate, and it contains the tongue. The salivary glands and tonsils are accessory organs of the oral cavity.

The mouth opens into the pharynx which continues into the esophagus. The esophagus in its turn continues into the stomach. Within the stomach the walls of the stomach have an abundance of tube like glands. These are the glands that release all the stomach acid which in turn begins to digest all the food it has received. The stomach leads to the small intestine. The small intestine itself is comprised of many different structures including the duodenum, the liver, the gallbladder and the pancreas. by digestive system blog

The next segment of the small intestine is the jejunum. The jejunum has small glands along it which help it in its major task of absorption. Father the jejunum we reach the ileum, the last segment of the small intestine. After the ileum comes the larger intestine. The purposes of the larger intestine are to convert undigested food into feces. The segments of the large intestine include the cecum, the ascending, transverse, descending and sigmoid colons and finally the rectum
