Download file to see previous pages Different non-starch polysaccharides have unique physical-chemical properties very vital to their physiological properties owing to the structural variability. The physicochemical properties of NSP such as viscosity, water-holding capacity, fermentation, and the capacity to bind organic and inorganic molecules makes it an essential component of the diet. According to (Mann, et al., 2007), these physiological properties associated with their consumption include; a. Reduced bowel passage time and improved stool bulk. It helps prevent constipation by increasing bulk of the gut content by their ability to bind water, thus allowing easy passage through the human intestine. Hence speeds the passage of foods through the digestive system, which facilitates regular defecation. b. Reducing concentrations of post-prandial blood glucose and /or insulin. This means that it enhances improvements in glucose tolerance and the insulin response by adding bulk and weight to the diet. There are improvements in glucose tolerance and the insulin response since NSP attracts water.. c. Reducing concentrations of blood total and/or LDL cholesterol. It reduces hyperlipidemia, hypertension, and other coronary heart disease risk factors by lowering total and LDL cholesterol. d. Reduces the risk of colon cancer. There is the reduced risk of developing some cancers such as Colorectal through balancing intestinal pH and restricts the production of harmful by-products of protein. e. Improves gastrointestinal health. There are improvements in gastrointestinal health through toning of the gut muscles plus fermentation of NSP improves absorption of minerals, especially calcium. The short chain fatty acids assist to lower the pH of the colon, inhibiting the growth of pathogenic organisms, increasing mineral absorption, maintaining normal bowel structure and function, preventing or alleviating colon-based diarrhea, and stimulating the colonic blood flow and fluid and electrolyte uptake. ...Download file to see next pagesRead More

Advanced Clinical Nutrition

...Advanced Clinical Nutrition QUESTION Inflammation and CVD Describe the relationship between inflammation andcardiovascular disease. There is no proof to show that inflammation causes cardiovascular disease. However, it has been found that in cardiovascular diseases like myocardial infarcts (heart attacks), inflammation plays an important role. Inflammation is the response of the body to injurious agents, foreign bodies or disease causing organisms. The response of the body is aimed at getting rid of these substances from the body. Research is ongoing to show how inflammation plays a role in cardiovascular diseases like heart attack and stroke. Many theories have been advanced to explain this analogy. But...

...Nutrition Need/Problem ment The prevalence and incidence of obesity among young children has grown significantly. This is demonstrated by research reports which articulate the doubling of obesity among young children between the years of 4 and 5. In addition, the incidence of obesity among kindergarten children has been established to be more than 33%. Since obesity affects both the physical and cognitive functioning, the increased prevalence among children is a significant problem and concern within the country. It is I this regard that a program that is aimed at reducing the incidence and prevalence of this condition among preschool children is justifiable.

...?Other (s) Clinical Biochemistry and Advanced Assessment in Nutrition Similarities and differences between Pyruvate Dehydrogenase Complex and Branched Chain Ketoacid Dehydrogenase Complex There are a number of similarities and differences regarding the functionality and nutrient requirements of Pyruvate Dehydrogenase and Branched Chain Ketoacid Dehydrogenase enzyme complexes. Pyruvate dehydrogenase complex is an important enxyme complex that particularly works by transforming pyruvate into acetyl-CoA through a process known as pyruvate decarboxylation (Smolle 196). The resultant product (acetyl-CoA) is then normally used during the citric acid cycle to enhance cell respiration. Structurally and...

...Nutrition There are many diseases that can result in great problems including mortality and morbidity if not treated. Many of these diseases occur due to deficiency of an important nutrient. There are two forms of PEM, marasmus and kwashiorkor which despite belonging to the same category have considerable differences. Kwashiorkor is the disease that occurs due to deficiency of protein in the body. It is more commonly found in children then the adults. The typical onset of disease is most common in children of ages, one till five. Kwashiorkor may be caused by malnutrition, eating foods rich in carbohydrates and fats but not protein, having problems in gastrointestinal tract which inhibits absorption of protein or any...

... Zinc The appendages and the skin are rich in zinc although it is present in all other organs, fluids and tissues of the body (Bhowmik et al. 1344). It serves as a catalyst for enzyme responsible for the replication of the DNA, protein synthesis, and transcription of the gene and RNA (Bhowmik et al. 1351). At the cellular level, it is important for the survival of the cells. It is vital for a number of human functions, namely growth and development, immune and neuropsychiatric functions, bone metabolism and wound healing. In 1994, zinc was considered an essential human nutrient by the National research Council. The council set a daily allowance of 15 milligrams oral intake for males, 19 milligrams for females and 9 milligrams... Zinc The...
