Latest Research on Dietary Intake: Oct – 2019

Dietary Intake and Bioavailability of Polyphenols

The main dietary sources of polyphenols square measure reviewed, and also the daily intake is calculated for a given diet containing some common fruits, vegetables and beverages. phenolic resin acids account for regarding one third of the entire intake and flavonoids account for the remaining 2 thirds. the foremost luxuriant flavonoids within the diet square measure flavanols (catechins and proanthocyanidins), anthocyanins and their oxidisation product. the most polyphenol dietary sources square measure fruit and beverages (fruit juice, wine, tea, coffee, chocolate and beer) and, to a lesser extent vegetables, dry legumes and cereals. the entire intake is ∼1 g/d. massive uncertainties stay thanks to the shortage of comprehensive knowledge on the content of a number of the most polyphenol categories in food. Bioavailability studies in humans square measure mentioned. the utmost concentration in plasma seldom exceeds one μM when the consumption of 10–100 mg of one phenolic resin compound. [1]

Dietary intake and bone mineral density

Osteoporosis, a significant pathological state all told Western countries, may be a condition during which several dietary factors are concerned. to see the influence of diet on bone mass within the proximal leg bone, the intake of fourteen nutrients was measured in 159 Caucasian ladies, aged 23-75 years and bone mineral density (BMD) quantitated within the hip by twin gauge boson absorptiometry. BMD was additionally measured within the spine and bone mineral content (BMC) in the forearm by single gauge boson absorptiometry. No important correlation was found between current metal intake and bone mass at any web site. Iron was a positive predictor of BMD within the limb neck and alcohol intake a positive predictor of BMD in the trochanteric region of the proximal leg bone in biological time ladies by multivariate analysis analysis. Iron, atomic number 30 and metal intake were absolutely correlative with forearm BMC in biological time ladies. Iron and metal were important predictors of forearm BMC in biological time and biological time ladies severally by multivariate analysis analysis. [2]

Measurement of dietary intake in children

When youngsters and adolescents square measure the target population in dietary surveys many various respondent and observer issues surface. The psychological feature skills needed to self-report food intake embody Associate in Nursing adequately developed thought of your time, an honest memory and a focus span, and a data of the names of foods. From the age of eight years there’s a fast increase within the ability of kids to self-report food intake. However, whereas psychological feature skills ought to be totally developed by adolescence, problems with motivation and body image could hinder temperament to report. 10 validation studies of energy intake knowledge have incontestable  that mis-reporting, sometimes within the direction of under-reporting, is likely. Patterns of under-reporting vary with age, and square measure influenced by weight standing and also the dietary survey technique used. what is more, proof for the existence of subject-specific responding in dietary assessment challenges the belief that continual measurements of dietary intake can eventually acquire valid knowledge. sadly, the flexibility to sight mis-reporters, by comparison with likely energy needs, is proscribed unless elaborated activity info is accessible to permit the energy intake of every subject to be evaluated one by one.

Association between blood pressure and dietary intakes of sodium and potassium among US adults using quantile regression analysis NHANES 2007–2014

Hypertension has become a serious public health challenge, and former studies have determined associations between high blood pressure and atomic number 11, potassium, and atomic number 11 to metal magnitude relation. However, very little is understood regarding however the full time of vital sign (BP) is expounded to dietary intake of atomic number 11 and metal. This study aims to look at quantile-specific associations of vital sign with dietary intake of atomic number 11 and metal. it’s supported national-level, cross sectional information for US adults aged ≥18 years from the National Health and Nutrition Examination Survey (NHANES) 2007–2014. a complete of eleven,095 eligible subjects were enclosed during this study. Quantile regression (QR) models were wont to investigate spatial arrangement effects within the dietary intake of atomic number 11 and metal on vital sign by adjusting the unsupportive factors. [4]

Practices Relating to Dietary Intake of Pregnant Women Attending Antenatal Clinic at Primary Healthcare Centres in Ile-Ife, Nigeria

Background: Inadequate dietary intake throughout gestation could be a primary proximate determinant of poor maternal and kid health. Maternal dietary practices connected info is helpful for coming up with acceptable interventions. This study was so designed to document dietary intake-related practices of pregnant girls attending prenatal  Clinics (ANCs) in Ile-Ife, Nigeria.

Design and Methods: The cross-sectional study concerned a complete of 530 willing girls attending ANCs in thirty five primary health care centers.  A pre-tested form including participants’ socio-demographic info and dietary practices measures were accustomed collect information. information were analysed victimisation descriptive statistics and Chi-square.
