Nutrition And Digestion Essay

The above explanation of digestion occurs in a ‘normal’ functioning body. There are several dilemmas involving digestion that the human body may encounter with progressed age, disease, or improper mechanics, such as lack of teeth. A major threat involving a decrease in digestion ability is malnutrition. Malnutrition does not simply refer to not eating, but also encompasses insufficient absorbance of nutrients once food has been eaten. There is a wide array of factors that may lead to malnutrition in an individual. Mechanically, the lack of teeth is a simple but yet common reason of decreased nutrition intake. Though salivary glands are stimulated upon the introduction of food to the mouth, a person with no teeth tends to avoid the more strenuous foods to chew, such as meats, carrots, lettuce, and nuts, and become partial to a lot of soft foods like potatoes and eggs, which may not necessarily be the most nutritious or balanced. Individuals with gum disease may have all their teeth, but it can become sore for them to chew their meals and, as a result, the eating dwindles. Jaw injuries or surgeries can cause discomfort and may temporarily hinder proper

The colon also known as the large intestine is an important contributor to the gastrointestinal tract. After food is absorbed in the small intestine it is pushed into the large intestine where the remaining water and vitamin k is absorbed. This is where the absorption water is most important in the G.I tract in keeping excretions regular. Also, the colon is a rich source of microorganisms. Bacteria in the colon assist in the digestion of nutrients we are not able to do because we lack those enzymes that specifically breakdown carbohydrates. To disrupt the balance of the microorganisms or bacteria would in fact cause more harm to your health.

Which then leads to weight loss and an unhealthy life style as the body is being deprived of essential vitamins and important food groups such as carbohydrates, fat and fibre, it can also cause constipation or diarrhoea as the blockages either won’t allow any waste to be released or it allows all the essential nutrients to be lost.

Therefore more bile salts are released between meals because there is no-longer a place to store them. This increased amount of bile salts will be too much for the small intestines to reabsorb. The excess bile salts will then spill over into the large intestines and blood stream and acts as a laxative causing diarrhea.

The human body is an intricate system compiled of organs, tissues and cells. Working simultaneously, these structures do not allow room for error. The digestive system is crucial system, for if error occurs within, the entire body will begin to shut down. Cirrhosis is one of the numerous digestive disorders that may occur.

Nutrition is important for professional athletes for a variety of reasons such as strength, personal health and fitness. The aim of this assignment is to find out what types of foods and combinations should an athlete consume 24 hours leading up to a game. The major section of this assignment is to find out what diets and foods help give athletes good nutrition before playing a match. These diets and foods should be consumed by most young people if they would like to be match fit and healthy. Another major item in this assignment is the food consumed by you and the strengths and weaknesses in your diet and how they could be improved.

Healthy digestion is crucial for health and wellbeing. Everything we ingest has a purpose, either it will nourish the body and act as fuel or will lead to various health conditions, some can be minor but while some lead to chronic disease. If our digestive system is not working properly, even with the best diet, nutrient absorption will be reduced.

The stomach, being the size of a smartphone, will be responsible for the storage of food so that there is enough time to properly digest larger meals (Taylor). Within the stomach, there are enzymes and hydrochloric acid that will be secreted to continue the breaking down of the food (Taylor). This breaking down of the food will disintegrate the food making it into a source of energy that will be slowly absorbed until getting into the small intestine. After the meals have been broken down, the stomach will slowly empty the substances inside into the small intestine and this process is called “chyme” (“Your Digestive System & How It works”). The small intestine, being twenty feet long in length, is divided into three parts which are the duodenum, jejunum, and ileum (Robinson). The duodenum is responsible for continuing the breaking down of the food, while both the jejunum and ileum are responsible of extracting all of the nutrients from the food (Robinson). As the food leaves the small intestine, 90% of the nutrients will be extracted to be absorbed

At that very moment your food enters your mouth the digestion process starts. Chewing is the mechanical digestion process that breaks your food into smaller pieces that are easier to digest. While in your mouth saliva secreted from the salivary glands, which is the chemical digestion, is mixed with your food to begin the process of breaking down the food into a simpler form your body can use and absorb. During this chemical digestion there are three types of saliva produced from the different types of food.

Carbs- carbohydrates are a vital source of our energy within the body. Carbs are the key nutrients that give our brains and red blood cells their energy. These carbs also come in different forms such as Fiber, which is a very important form or nutrient to our bodies. This is because fiber is tremendously important to our bodys digestive system. If someone took in too much fiber within their diet, it could cause terrible diarrhea. On the other hand, if someone does intake enough fiber in the daily diet, this could result in the cause of colon cancer. Another key nutrient for our body is fats. There are 4 types of fats ( monounsaturated, saturated, polyunsaturated, and finally trans fat). These fats help our body digest or break down vitamins D,E,A,K. the final key nutrient for our body is protein. The nutrient Protein helps the body with regulations of various hormones, fluids, enzymes, and antibodies.

The small intestine is where most of the nutrient transfer is made to the Cardiovascular System so the rest of the body is maintained and healthy.

If you don’t have strong enough stomach acid then you cannot digest your food properly because the PH is too high. This

If you do a Google search on the phrase "leaky gut", you 'll find an abundance of information regarding the importance of digestion for our bodies. What we eat and how we eat are important aspects to how we look and feel. Eating nutritious food without digesting it properly will still leave you sick and malnourished. In reading David Saxton 's book on the Puritan

Good digestion is the foundation of good health; for instance, one could theoretically eat a perfect diet and take a multivitamin, but if these nutrients aren’t optimally absorbed all that’s left is wasted time. The stomach isn’t just one giant food processor and storage system, when you really think about it, the stomach is also the barrier between the outside world and your internal physiology.

To date, tremendous efforts have been made to predict the magnitude of in vivo DDIs. Several well-established animal and cell-based models are used for studying intestinal metabolism. The traditional method of predicting intestinal metabolism using information from preclinical studies in animals has changed to the use of physiologically based pharmacokinetic models (PBPK) with in vitro-in vivo extrapolation. These models allowed incorporating intestinal transit times and heterogeneous expression levels of drug-metabolizing enzymes and transport proteins into mechanistic predictions of intestinal absorption and metabolism. In addition, these models divided the gastrointestinal tract into several compartments
