Digestion Research Paper

The DRI recommends that I consume a minimum of 25 grams of fiber daily. My current intake of dietary fiber falls short of meeting my recommended amount. Fiber is important in a healthy diet. It is beneficial in maintaining good digestive health and with prevention of diseases, including colon and rectal cancer. Adequate amounts of fiber also decrease the risk of heart disease by lowering the amount of LDL cholesterol within the blood.

Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication, or chewing, performed by the teeth. The purpose of chewing

When a person thinks of digestion they usually think about what happens in the stomach. A lot has happened to digest the food way before it gets to the stomach. It starts in the mouth or oral cavity. It is a process called mechanical digestion. First, Mastication begins. Mastication is the chewing of the food. A person will crush, grind and tear the food apart. That gets the food ready for deglutition. Deglutition is the swallowing of the mashed up food. When we swallow peristalsis begins. Peristalsis is what happens

The tongue and teeth mechanically break food into smaller pieces through process of mastication, salivary enzymes in the saliva begin the process of chemical digestion.

The mouth is where the digestion first begins as firstly the scent of the food will travel to the nose causing the salivary glands in the mouth to produce saliva as there are three pairs that do this. As you are chewing the food with your teeth the food starts to get broken down more saliva is produced along with the breaking down. The secretion will be transferred into the mouth and the tongue as the salivary glands are causing it to do this. Also, the digestive juice contains an enzyme which is known as salivary amylase which now begins the digestion of carbohydrates as well as lubricating the mouth in order to help with the bolus formation.

he digestive system is a physiological marvel, composed of finely orchestrated chemical and physical activities. The food we ingest must be broken down to its molecular form for us to get the nutrients we need, and digestion involves a complex sequence of mechanical and chemical processes designed to achieve this goal as efficiently as possible. As food passes through the gastrointestinal tract, it is progressively broken down by the mechanical action of smooth muscle and the chemical action of enzymes until most nutrients have been extracted and absorbed into the blood.

Smell that yummy pumpkin pie? Mouth is getting watery. You start to salivate. That is the beginning process of digestion getting you ready to eat that delicious pumpkin pie. That’s why people say digestion starts in your mouth. The digestive tract also known as the alimentary canal, the liver, pancreas, and other abdominal organs make up the digestive system. The esophagus, the stomach, and the intestines, (from the mouth to the anus) all belongs in the alimentary canal. In an adult the whole

Eating more fiber will help improve your digestive system and improve the intake of carbohydrates and lipids. A greater intake of fiber will

Fibre is important because it: stimulates the digestive tract and helps it work efficiently; encourages the presence of health-giving bacteria in the large intestine. A good source of fibre is include brown rice, high fibre/multigrain gluten-free breads.

The digestive process begins at the mouth. When you eat food, obviously, it enters your mouth first. Then, in the mouth mechanical digestion, the physical act of breaking down food, happens through the means of your teeth. Chemical Digestion , the act of breaking down food through chemicals, also happens in the mouth due to the enzymes found in the saliva. Saliva

The digestion starts here as soon as you take a bite of your food. By chewing your food it breaks the food into pieces so that is easy to digest, and the saliva mixes with food to begin the process of breaking it down into a form that your body can take. The throat also known as the (pharynx) is the next stop and from here; the food goes to the esophagus or swallowing tube. The esophagus is a muscular tube extending from the pharynx to the stomach. By means of a series of contractions, called peristalsis, the esophagus delivers food to the stomach.

Fiber is essential for healthy digestion. It also helps regulate blood pressure and can reduce the risk of heart disease. If you are not eating a lot of fruits, vegetables and whole grains, then you may be deficient in fiber. Most people are not getting enough fiber.

Fiber can help lower cholesterol levels and reduce the risk of diabetes (a risk factor for heart disease) and certain types of cancer. “We recommend about 25 grams of fiber a day, for men a bit more. It’s based on your weight,” Young says. “Most Americans eat much, much less than that. If you follow a good diet, you’ll get enough, but so many of us don’t.”

The digestive system is a group of organs working together to convert food into energy. The food digested is also tied into basic nutrients to feed the body. The digestive system is something called the tube within a tube. This is because it is a hollow structure with two openings that run the height of your body. The digestive tract consists of two parts the gastrointestinal tract known as GI tract and a set of accessory organs. GI tract starting at the oral cavity, through abdominal cavity and end at the anus. Major accessory organs include pancreas, liver, and gallbladder. There are 5 basic processes the digestive system have. The processes include and ingestion, mixing digestion, absorption, and defecation. Ingestion is the first step which is when the food and liquids are taken in the mouth and eaten. Mixing is when the smooth muscles in the walls of the GI tract mixes the food and send it through the tract. Next is digestion where the food is broken down by mechanical and chemical processes. Absorption is the epithelial

According to the Mayo Clinic, probiotics are good bacteria that are either the same as or similar to the bacteria that occur naturally in your body. Probiotics can be found in some food supplements, and works by decreasing the number of "bad" bacteria in your gut that can cause infections or inflammation and restoring bacterial balance.
