Fat is present in most foods. It provides a unique texture, flavor, and aroma to the food it is found in. [2] While fat is essential to life, it can be detrimental to health when consumed in excess of physiological requirements. [1] High fat diets increase risk of heart disease, weight gain, and some cancers.
[1] [3] Macronutrient composition (carbohydrate, protein or fat) of diets affects circulating SCFAs. [4] Acetate, propionate and butyrate are the three most common SCFAs. [ 3 ] Butyrate is particularly important for colon health because it is the primary energy source for colonocytes (the epithelial cells of the colon).
For example, the anti-obesity drug orlistat causes a percentage of fat to pass through the digestive tract undigested. [9] Amylase inhibitors prevent the action of enzymes that break the glycosidic bonds of starches and other complex carbohydrates, preventing the release of simple sugars and absorption by the body. Like lipase inhibitors, they ...
Visceral fat, which is more metabolically active than subcutaneous fat, has been found to produce many enzymatic signals, e.g. resistin, which increase insulin resistance and circulating VLDL particle concentrations, thus both increasing LDL particle concentrations and accelerating the development of diabetes mellitus.
Lipid metabolism is often considered the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat. [5] Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function. [6]
Malabsorption is a state arising from abnormality in absorption of food nutrients across the gastrointestinal (GI) tract. Impairment can be of single or multiple nutrients depending on the abnormality. This may lead to malnutrition and a variety of anaemias. [1]
Orlistat (Xenical) and cetilistat reduce intestinal fat absorption by inhibiting pancreatic lipase, an enzyme that breaks down triglycerides in the intestine. Without this enzyme, triglycerides from the diet are prevented from being hydrolyzed into absorbable free fatty acids and are excreted undigested. [ 31 ]
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [ 2 ] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
