In nine states purchase hoodia 400 mg fast delivery, blacks were arrested on drug charges at rates more than seven times white rates hoodia 400 mg with visa. In each of 43 cities examined by the Sentencing Project hoodia 400mg with amex, blacks in 2003 were arrested at higher rates than whites, ranging from a high of 8. Between 1980 and 2003, the black-to-white ratio of drug arrests increased in all but five of the cities, and it doubled in 21 cities (King 2008, pp. Beckett, Nyrop, and Pfingst (2006) calculated black and white drug arrest rates and ratios in 18 mid-sized cities in 2000 and found ratios ranging from 1. In the 75 largest counties, 49 percent of felony drug defendants are non-Hispanic blacks and 26 percent are non- Hispanic whites (Cohen and Kyckelhahn 2010). Incarceration The racial disparity evident in drug arrests increases as cases wend their way through the criminal justice system. Black defendants constitute 44 percent and white defendants 55 percent of persons convicted of drug felonies in state courts. Among defendants convicted of drug felonies, 61 percent of whites and 70 percent of blacks are sentenced to incarceration. Whites sentenced to incarceration for drug felonies received a mean maximum sentence length of 29 months, compared with 34 months for blacks (Durose, Farole, and Rosenmerkel 2009). As Table 3 shows, the number of African Americans admitted to state prison as new court commitments on drug charges has consistently exceeded the number of whites during the past 10 years.

Among the 97,239 federal prisoners serving time for drug offenses at the end of 2009, 43. For most serious crimes, arrest and victimization survey data provide useful—although incomplete—information on the demographics of criminal offending (Like-Haislip, in this volume). Arrests primarily reflect geographic deployment of police personnel and law enforcement priorities. The principal source of national data on drug offenders comes from national surveys and self-report studies. National youth surveys have also included questions on drug offending that yield useful information. The available data leave little doubt that racial differences in drug offending do not account for the stark racial disparities in arrests and incarceration. Decades of arrest and incarceration have apparently had little impact on the use of illicit drugs.

Click to view larger Figure 2 Percentage by Race of Illicit Drug Use in Lifetime, Past Year, and Past Month Among Persons Aged 12 and Over Note: Total includes all users regardless of race or ethnicity. But because the white population in the United States is substantially greater than the black, comparable rates of drug use result in far4 greater numbers of white users. As Figure 3 shows, for example, slightly more than six times as many whites (86,537,000) report having used drugs in their lives as blacks (13,629,000).

Subscriber: Univ of Minnesota - Twin Cities; date: 23 October 2013 Race and Drugs Figure 4 shows that rates of drug use by type of drug do not substantially differ for whites, blacks, and Hispanics. African Americans rates are somewhat higher than whites’ for the listed drugs except prescription drugs, but because of the different sizes of the black and white populations, the numbers of white users for every drug greatly exceed those for black users, as Figure 5 shows. The most heavily used drug is marijuana; the number of white marijuana users was more than four times the number of black users. Prescription drugs are the second most prevalent type of illicit drug use: among persons reporting using them in the preceding month, 5,145,000 were white and 602,000 were black.

Indigestible components of starch hydrolysates generic hoodia 400mg online, as a result of heat and enzymatic treatment cheap 400 mg hoodia visa, yield indigestible dextrins that are also called resistant maltodextrins generic hoodia 400 mg with mastercard. Unlike gums, which have a high viscosity that can lead to problems in food processing and unpleasant organoleptic properties, resistant maltodextrins are easily added to foods and have a good mouth feel. Resistant maltodextrins are produced by heat/acid treat- ment of cornstarch, followed by enzymatic (amylase) treatment. The average molecular weight of resistant maltodextrins is 2,000 daltons and consists of polymers of glucose containing α-(1-4) and α-(1-6) glucosidic bonds, as well as 1-2 and 1-3 linkages. Resistant dextrins can potentially be classified as Functional Fibers when sufficient data on physiological benefits in humans are documented. Resistant starch is naturally occurring, but can also be produced by the modification of starch during the processing of foods. Resistant starch is estimated to be approximately 10 percent (2 to 20 percent) of the amount of starch consumed in the Western diet (Stephen et al. Along the gastrointestinal tract, properties of fiber result in differ- ent physiological effects. Effect on Gastric Emptying and Satiety Consumption of viscous fibers delays gastric emptying (Low, 1990; Roberfroid, 1993) and expands the effective unstirred layer, thus slowing the process of absorption once in the small intestine (Blackburn et al. A slower emptying rate means delayed digestion and absorp- tion of nutrients (Jenkins et al. For example, Stevens and coworkers (1987) showed an 11 percent reduction in energy intake with psyllium gum intake. Postprandial glucose concentration in the blood is thus lower after the consumption of viscous fiber than after consumption of digestible carbohydrate alone (Benini et al. The extended presence of nutrients in the upper small intestine may promote satiety (Sepple and Read, 1989). Fermentation Fibers may be fermented by the colonic microflora to carbon dioxide, methane, hydrogen, and short-chain fatty acids (primarily acetate, propi- onate, and butyrate). Foods rich in hemicelluloses and pectins, such as fruits and vegetables, contain Dietary Fiber that is more completely ferment- able than foods rich in celluloses, such as cereals (Cummings, 1984; Cummings and Englyst, 1987; McBurney and Thompson, 1990). There appears to be no relationship between the level of Dietary Fiber intake and fermentability up to very high levels (Livesey, 1990). Butyrate, a four-carbon, short-chain fatty acid, is the preferred energy source for colon cells (Roediger, 1982), and lack of butyrate production, absorption, or metabo- lism is thought by some to contribute to ulcerative colitis (Roediger, 1980; Roediger et al. Others have suggested that butyrate may be protec- tive against colon cancer (see “Dietary Fiber and the Prevention of Colon Cancer”). However, the relationship between butyrate and colon cancer is controversial and the subject of ongoing investigation (Lupton, 1995). Once absorbed into the colon cells, butyrate can be used as an energy source by colonocytes (Roediger, 1982); acetate and propionate travel through the portal vein to the liver, where propionate is then utilized by the liver. A small proportion of energy from fermented fiber is used for bacterial growth and mainte- nance, and bacteria are excreted in feces, which also contain short-chain fatty acids (Cummings and Branch, 1986). Differences in food composi- tion, patterns of food consumption, the administered dose of fiber, the metabolic status of the individual (e. Because the process of fermentation is anaerobic, less energy is recovered from fiber than the 4 kcal/g that is recovered from carbohy- drate. While it is still unclear as to the energy yield of fibers in humans, current data indicate that the yield is in the range of 1. Physiological Effects of Isolated and Synthetic Fibers This section summarizes the fibers for which there is a sufficient data- base that documents their beneficial physiological human effects, which is the rationale for categorizing them as Functional Fibers. It is important to note that discussions on the potential benefits of what might eventually be classified as Functional Fibers should not be construed as endorsements of those fibers. While plant-based foods are a good source of Dietary Fiber, isolated or synthetic fibers have been developed for their use as food ingredients and because of their beneficial role in human health. In 1988 Health Canada published guidelines for what they considered to be “novel fiber sources” and food products containing them that could be labeled as a source of fiber in addition to those included in their 1985 definition (Health Canada, 1988). The rationale for these guidelines was that there were safety issues unique to novel sources of fiber, and if a product was represented as containing fiber, it should have the beneficial physiological effects associated with dietary fiber that the public expects. The guidelines indicated that both safety and efficacy of the fiber source had to be estab- lished in order for the product to be identified as a source of dietary fiber in Canada, and this had to be done through experiments using humans.
