    This study used the 1987-88 USDA Nationwide Food Consumption Survey to investigate the contribution meat products make to intakes of nutrients at risk of inadequate or excessive consumption by women. The study is unique in that meat nutrients were extracted from mixed dishes, providing a more accurate picture of consumption. Cluster analysis was used to classify nonpregnant, nonlactating women 19 years and older based on their consumption patterns of total meat and individual meats (beef, poultry, processed meats, pork and seafoods) as percent of caloric intake. Total fat and SFA intakes exceeded National Research Council (NRC) goals regardless of meat intake level. Results indicate an inverse relationship of total energy intake and calories from all meats. Total fat intakes had a small, positive relationship with meat calories. Saturated fatty acid (SFA) intakes appeared to have a weak, positive relationship. Vitamin B6 intakes were below the RDA in all clusters but were adequate relative to protein intakes. Iron intakes of women under age 51 were less than 70% of RDA. Zinc had a strong, positive association with total meat intake. Individuals that did not consume beef met only 48% to 62% of RDA. An analysis to determine if increases in vitamin 86, iron, and zinc seen with high meat intake were due to increased meat or caloric intake showed that total fat and SFA increased 12% and 8%, respectively, when ≤ 2 ounces of meat and ≤ 6 ounces of meat were consumed. All of the increase was derived from meat. Vitamin B6, iron, and zinc increased 100%, 59%, and 132%, respectively; 77%, 64%, and 90% were due to meat. In summary, women\u27s diets were significantly low in iron and zinc, which are strongly present in meat products, especially beef. Intakes of vitamin B6 appear to meet calculated needs, but some women may be at risk due to the increased requirements found with age and the low bioavailabilty of plant sources. Attempting to reduce total fat and SFA intakes by reducing meat intake, especially red meat, may have a deleterious effect on women\u27s nutrient status

    Nonleptonic two-body charmless B decays involving a tensor meson in the Perturbative QCD Approach

    Full text link
    Two-body charmless hadronic B decays involving a light tensor meson in the final states are studied in the perturbative QCD approach based on kTk_T factorization. From our calculations, we find that the decay branching ratios for color allowed tree-dominated decays Ba20π+B\to a_{2}^{0}\pi^{+} and Ba2π+B\to a_{2}^{-}\pi^{+} modes are of order 10610^{-6} and 10510^{-5}, respectively. While other color suppressed tree-dominated decays have very small branching ratios. In general, the branching ratios of most decays are in the range of 10510^{-5} to 10810^{-8}, which are bigger by one or two orders of magnitude than those predictions obtained in Isgur-Scora-Grinstein-Wise II model and in the covariant light-front approach, but consistent with the recent experimental measurements and the QCD factorization calculations. Since the decays with a tensor meson emitted from vacuum are prohibited in naive factorization, the contributions of nonfactorizable and annihilation diagrams are very important to these decays, which are calculable in our perturbative QCD approach. We also give predictions to the direct CP asymmetries, some of which are large enough for the future experiments to measure. Because we considered the mixing between f2f_{2} and f2f_{2}', the decay rates are enhanced significantly for some decays involving f2f_{2}^{\prime} meson, even with a small mixing angle.Comment: 26 pages, 2 figure

    Annihilation Type Radiative Decays of BB Meson in Perturbative QCD Approach

    Full text link
    With the perturbative QCD approach based on kTk_T factorization, we study the pure annihilation type radiative decays B0ϕγB^0 \to \phi\gamma and B0J/ψγB^0\to J/\psi \gamma. We find that the branching ratio of B0ϕγB^0 \to \phi\gamma is (2.70.60.6+0.3+1.2)×1011(2.7^{+0.3+1.2}_{-0.6-0.6})\times10^{-11}, which is too small to be measured in the current BB factories of BaBar and Belle. The branching ratio of B0J/ψγB^0\to J/\psi \gamma is (4.50.50.6+0.6+0.7)×107({4.5^{+0.6+0.7}_{-0.5-0.6}})\times10^{-7}, which is just at the corner of being observable in the BB factories. A larger branching ratio BR(Bs0J/ψγ)5×106BR(B_s^0 \to J/\psi \gamma) \simeq 5 \times 10^{-6} is also predicted. These decay modes will help us testing the standard model and searching for new physics signals.Comment: 4 pages, revtex, with 1 eps figur
