Dietary Treatment For Epilepsy, Margaret Rebecca Sinclair

Margaret R.Sinclair

Dietary treatments for epilepsy have been used since the early 1920s, however, the use of these treatments has been replaced by anticonvulsant drugs. In the past ten years there has been a reemergence of the use of dietary treatments for epilepsy. These dietary treatments are referred to as Ketogenic Diets. There are three types of ketone diets: Classic Ketogenic Diet (KD), Medium-chain-triglyceride Ketogenic Diet (MTC), and the Modified Atkins Diet (MAD). Theses dietary treatment utilize a high-fat, adequate protein and very low carbohydrates diet to control seizures. The purpose of this report is to provide a comprehensive overview of dietary …

Inadequate Feeding Of Infant And Young Children In India: Lack Of Nutritional Information Or Food Affordability?, Nisha Malhotra

Nisha Malhotra

Why does child malnutrition persist in India? Amongst the fastest growing economies over the last two decades, India has struggled to make progress in the health of its children. In this article the author argues that the reason malnutrition persists is not limited to poverty or inadequate access to food; but that a lack of nutritional knowledge amongst families plays a very important role.

Scientific Abstract Objective: Despite a rapidly growing economy and rising income levels in India, improvements in child malnutrition have lagged. Data from the most recent National Family Health Survey reveal that the infant and young child …

Phaseolus Beans: Impact On Glycaemic Response And Chronic Disease Risk In Human Subjects, Andrea M. Hutchins, Donna M. Winham, Sharon V. Thompson

Donna Winham

Consumption of Phaseolus vulgaris bean species such as pinto, black, navy or kidney may be beneficial in the prevention and treatment of chronic diseases. In particular, conditions that are promoted by increased glycaemic stress (hyperglycaemia and hyperinsulinaemia) including diabetes, CVD and cancer seem to be reduced in individuals who eat more of these beans. The present paper discusses the influence of P. vulgaris species on glycaemic response and the impact that relationship may have on the risk of developing diabetes, CVD and cancer.

Perceptions Of Flatulence From Bean Consumption Among Adults In 3 Feeding Studies, Donna M. Winham, Andrea M. Hutchins

Donna Winham

Background: Many consumers avoid eating beans because they believe legume consumption will cause excessive intestinal gas or flatulence. An increasing body of research and the 2010 Dietary Guidelines for Americans supports the benefits of a plant-based diet, and legumes specifically, in the reduction of chronic disease risks. The purpose of the current research was to investigate the perception of increased flatulence and gastrointestinal discomfort among participants who consumed a ½ cup of beans daily for 8 or 12 weeks. Methods: Participants in three studies to test the effects of beans on heart disease biomarkers completed the same weekly questionnaire to …

A Comparison Of Iron Absorption In Adults And Infants Consuming Identical Infant Formulas, Richard F. Hurrell, Lena Davidsson, Manju B. Reddy, Peter Kastenmayer, James D. Cook

Manju B. Reddy

Fe absorption was estimated in adults and infants from the erythrocyte incorporation of Fe isotopes added to infant formula. Fe absorption was measured in adults using radioisotopes, and in infants with a stable-isotope technique. In adults, the geometric mean Fe absorption from a ready-to-feed soya formula with its native phytic acid content was 2.4%. This increased to 6.0 % (P < 0.05) after almost complete dephytinization. In infants, mean Fe absorption values were 3.9 and 8.7% respectively from the same products (P(O.05). In adults, mean Fe absorption from a spray-dried soya formula containing 110 mg ascorbic acid was 4.1 %, increasing to 5.3 % (P < 0.05) when ascorbic acid was doubled to 220 mgfl. In infants, mean Fe absorption values were 5.7 and 9.5 % (P < 0.05) from the same products. Mean Fe absorption from a milk-based formula was 6.5 % in adults compared with 6.7 % in infants. All meals in the adult and infant studies were fed using an identical meal size of 217 g. Increasing the meal size threefold in adults did not change fractional Fe absorption. Mean Fe absorption values for each meal were lower in adults than in infants, but the relative inhibitory effect of phytic acid and the enhancing effect of ascorbic acid were similar. We conclude that Fe absorption studies in adults can be used to assess the influence of enhancers and inhibitors of Fe absorption in infant formulas fed to infants. Further studies, however, are required to extend these findings to weaning foods and complete meals.

Iron Regulatory Protein 1 Is Not Required For The Modulation Of Ferritin And Transferrin Receptor Expression By Iron In A Murine Pro-B Lymphocyte Cell Line, Kevin Schalinske, Kenneth P. Blemings, Daniel W. Steffen, Opal S. Chen, Richard S. Eisenstein

Kevin Schalinske

Iron regulatory proteins (IRPs) are cytoplasmic RNA binding proteins that are central components of a sensory and regulatory network that modulates vertebrate iron homeostasis. IRPs regulate iron metabolism by binding to iron responsive element(s) (IREs) in the 5* or 3* untranslated region of ferritin or transferrin receptor (TfR) mRNAs. Two IRPs, IRP1 and IRP2, have been identified previously. IRP1 exhibits two mutually exclusive functions as an RNA binding protein or as the cytosolic isoform of aconitase. We demonstrate that the BayF3 family of murine pro-B lymphocytes represents the first example of a mammalian cell line that fails to express IRP1 …

Oral Contraceptives And Fat Patterning In Young Adult Women, Ruth E. Litchfield, Katharine K. Grunewald

Ruth E. Litchfield

. Ninety white nulliparous young women (18-26 years of age) participated in a double-blind study designed to compare fat patterning and other physical measurements in oral contraceptive (OCA) users and non- users. Oral contraceptive users (N = 30) and non-users (N = 60) were matched on a 1:2 basis for height and weight. The OCA users and non- users had similar circumference and skinfold measurements, except that OCA users had larger axilla skinfold measurements. Progestational activity of the oral contraceptives was not associated with any measurements taken. However, estrogenic activity was positively correlated with measured body weight, body mass index, …
