The triacylglycerols are then assembled together with cholesterol trusted clomiphene 25mg, phospholipid buy discount clomiphene 50 mg line, and apoproteins into chylomicrons generic 100mg clomiphene fast delivery. Following absorption, fatty acids of carbon chain length 12 or less may be transported as unesterified fatty acids bound to albumin directly to the liver via the portal vein, rather than acylated into triacylglycerols. Dietary phospholipids are hydrolyzed by pancreatic phospholipase A2 and cholesterol esters by pancreatic cholesterol ester hydrolase. The lyso- phospholipids are re-esterified and packaged together with cholesterol and triacylglycerols in intestinal lipoproteins or transported as lysophospholipid via the portal system to the liver. These particles enter the circulation and within the capillaries of muscle and adipose tissue. Chylomicrons come into contact with the enzyme lipo- protein lipase, which is located on the surface of capillaries. Most of the fatty acids released in this process are taken up by adipose tissue and re-esterified into triacylglycerol for storage. Triacylglycerol fatty acids also are taken up by muscle and oxidized for energy or are released into the systemic circulation and returned to the liver. Most newly absorbed fatty acids enter adipose tissue for storage as triacylglycerol. However, in the postabsorptive state or during exercise when fat is needed for fuel, adipose tissue triacylglycerol under- goes lipolysis and free fatty acids are released into the circulation. Hydrolysis occurs via the action of the adipose tissue enzyme hormone-sensitive lipase. When plasma insulin concentrations fall in the postabsorptive state, hormone-sensitive lipase is activated to release more free fatty acids into the circulation. Thus, in the postabsorptive state, free fatty acid concentrations in plasma are high; conversely, in the postprandial state, hormone-sensitive lipase activity is suppressed and free fatty acid concentrations in plasma are low. When free fatty acid concen- trations are relatively high, muscle uptake of fatty acids is also high. As in liver, fatty acids in the muscle are transported via a carnitine-dependent pathway into mitochondria where they undergo β-oxidation, which involves removal of two carbon fragments. These two carbon units enter the citric acid cycle as acetyl coenzyme A (CoA), through which they are completely oxidized to carbon dioxide with the generation of large quantities of high- energy phosphate bonds, or they condense to form ketone bodies. However, the uptake of fatty acids in excess of the needs for oxidation for energy by muscle does result in temporary storage as triacylglycerol (Bessesen et al. High uptake of fatty acids by skeletal muscle also reduces glucose uptake by muscle and glucose oxidation (Pan et al. Oxidation of fatty acids containing up to 18 carbon atoms occurs mainly in the mito- chondria. Oxidation of excess fatty acids in the liver, which occurs in pro- longed fasting and with high intakes of medium-chain fatty acids, results in formation of large amounts of acetyl CoA that exceed the capacity for entry to the citric acid cycle. During starvation or prolonged low carbohy- drate intake, ketone bodies can become an important alternate energy substrate to glucose for the brain and muscle. High dietary intakes of medium-chain fatty acids also result in the generation of ketone bodies. This is explained by the carnitine-independent influx of medium-chain fatty acids into the mitochondria, thus by-passing this regulatory step of fatty acid entry into β-oxidation. Fatty acids of greater than 18 carbon atoms require chain shortening in peroxisomes prior to mitochondrial β-oxidation. The major pathway for triacylglycerol synthesis in liver is the 3-glycerophosphate pathway, which shows a high degree of specificity for saturated fatty acids at the sn-1(3) position and for unsaturated fatty acids at the sn-2 position. Fatty acids are generally catabolized entirely by oxidative processes from which the only excretion products are carbon dioxide and water. Small amounts of ketone bodies produced by fatty acid oxidation are excreted in urine. Fatty acids are present in the cells of the skin and intestine, thus small quantities are lost when these cells are sloughed. When saturated fatty acids are ingested along with fats con- taining appreciable amounts of unsaturated fatty acids, they are absorbed almost completely by the small intestine. In general, the longer the chain length of the fatty acid, the lower will be the efficiency of absorption. Studies with human infants have shown the absorption to be 75, 62, 92, and 94 percent of palmitic acid, stearic acid, oleic acid, and linoleic acid, respectively, from vegetable oils (Jensen et al. The absorption of palmitic acid and stearic acid from human milk is higher than from cow milk and vegetable oils (which are commonly used in infant formulas) because of the specific positioning of these long-chain saturated fatty acids at the sn-2 position of milk triacylglycerols (Carnielli et al. The intestinal absorption of palmitic acid and stearic acid from vegetable oils was 75 to 78 percent compared with 91 to 97 percent from fats with these fatty acids in the sn-2 position (Carnielli et al. Still, absorption of stearic acid was over 90 percent complete in healthy adults when contained in triacylglycerols of mixed fatty acids (Bonanome and Grundy, 1989). Following absorption, long-chain saturated fatty acids are re-esterified along with other fatty acids into triacylglycerols and released in chylomicrons.

Because certain micronutrients buy discount clomiphene 50mg, saturated fats buy clomiphene 50 mg with mastercard, and cholesterol are consumed mainly through animal foods buy clomiphene 25 mg on line, it is possible that diets low in saturated fat and cholesterol are associated with low intakes of these micronutrients. When the micronutrient intakes of Seventh-day Adventist vegetarians and nonvegetarians were measured, there were no significant reductions in micronutrient intakes with the lower saturated fat (7. Similarly, the intakes of most micronutrients were not significantly lower for vegans, except for vitamin B12 (0. Analysis of nutritionally adequate menus indicates that there is a mini- mum amount of saturated fat that can be consumed so that sufficient levels of linoleic and α-linolenic acid are consumed (as an example see Appendix Tables G-1 and G-2). Other than soy products that are high in n-6 and n-3 fatty acids, many vegetable-based fat sources are also high in saturated fatty acids, and these differences should be considered in plan- ning menus. To minimize saturated fatty acid intake requires decreased intake of animal fats (e. Saturated fatty acids can be reduced by choosing lean cuts of meat, trimming away visible fat on meats, and eating smaller por- tions. The amount of butter that is added to foods can be minimized or replaced with vegetable oils or nonhydrogenated vegetable oil spreads. Vegetable oils, such as canola and safflower oil, can be used to replace more saturated oils such as coconut and palm oil. Such changes can reduce saturated fat intake without altering the intake of essential nutrients. A reduction in the frequency of intake or serving size of certain foods such as liver (375 mg/3 oz slice) and eggs (250 mg/egg) can help reduce the intake of cholesterol, as well as foods that contain eggs, such as cheese- cake (170 mg/slice) and custard pie (170 mg/slice). There are a number of meats and dairy products that contain low amounts of cholesterol (e. Therefore, there are a variety of foods that are low in saturated fat and cholesterol and also abundant in essential nutrients such as iron, zinc, and calcium. Trans fatty acids are high in stick margarine and those foods containing vegetable shortenings that have been subjected to hydrogenation. Examples of foods that contain relatively high levels of trans fatty acids include cakes, pastries, doughnuts, and french fries (Litin and Sacks, 1993). Therefore, the intake of trans fatty acids can be reduced without limiting the intake of most essential nutrients by decreasing the serving size and frequency of intake of these foods, or by using unhardened oil. Several studies suggest that these changes are primarily due to a reduction in lipid uptake by adipocytes (Pariza et al. Blankson and coworkers (2000) conducted a study in overweight and obese men and women given either placebo or 1. After 12 weeks, none of the groups exhibited significant reductions in body weight or body mass index. Ip and Scimeca (1997) conducted a study in female rats chemically induced for mammary tumors and fed a diet containing either 2 percent or 12 percent linoleic acid. A number of adverse clinical effects, including impaired laxation and increased risk of cancer, obesity, heart disease, and type 2 diabetes, have been associated with the chronic consumption of low amounts of Dietary Fiber or Functional Fiber. The studies to support a beneficial role of these fibers are reviewed in Chapter 7. Certain animal studies have shown that some fibers can actually enhance mineral absorption (Demigné et al. There are several potential mechanisms by which ingestion of Dietary Fiber may actually enhance mineral status. For example, a more acidic pH in the colon is produced with fiber fermentation, and this results in more ionized calcium, which is better absorbed (Rémésy et al. Dietary Fiber in the colon can also stimulate bacterial fermentation, which has been associated with increases in calcium, magnesium, and potassium absorption (Demigné et al. Many fiber sources, such as karaya gum, sugar beet fiber, and coarse bran, are also excellent sources of minerals (Behall et al. Several investigators have shown that inulin and fructooligosaccharides actually enhance calcium and magnesium absorption (Coudray et al. There is also indirect evidence of this same enhancement with calcium in humans (Trinidad et al. A direct effect of fiber on mineral absorption has also been reported in humans where inulin increased the apparent absorption and balance of calcium (Coudray et al. Gastrointestinal distress can occur with the consumption of high fiber diets, but this often subsides with time. Epidemiological analysis from 53 devel- oping countries indicated that 56 percent of deaths in young children were due to the potentiating effects of malnutrition in infectious diseases (Pelletier et al. The increased duration or susceptibility to infec- tious diseases such as respiratory infections and diarrhea are due, in part, to the involvement of protein in immune function. Impaired Growth Low protein intake during pregnancy is correlated with a higher inci- dence of low birth weight (King, 2000). These deficits can be corrected by the provision of a high protein diet (Badaloo et al. Low Birth Weight Rush and coworkers (1980) found decreases in both gestational length and birth weight and increases in very early premature births and mortal- ity with high density protein supplementation (additional 40 g/d) in poor, black pregnant women at risk of having low birth weight infants. In contrast, Adams and coworkers (1978) reported no differences from the controls in mean birth weights of infants of mothers at risk of having a low birth weight infant when these women were supplemented with 40 g/d of protein.
