PREDICTING SENSORY COHESIVENESS, HARDNESS AND SPRINGINESS OF SOLID FOODS FROM INSTRUMENTAL MEASUREMENTS

JOURNAL OF TEXTURE STUDIES, Issue 2 2008
R. DI MONACO
ABSTRACT The sensory evaluation of cohesiveness, hardness and springiness of 15 solid food samples was performed by eight trained assessors. The rheologic response of the 15 samples was estimated by performing cyclic compression tests and stress,relaxation tests. From the force,deformation curves of the first two cycles of the compression test, texture profile analysis parameters related to cohesiveness, hardness and springiness were calculated. Young's modulus (E), strain (di) and stress (si) at peak as well as irrecoverable strain (ri) and irrecoverable work (Li) were monitored during the first five cycles. From the stress,relaxation response, Peleg's linearization model parameters, K1 and K2, were estimated by best-fit regression. These parameters were used for predicting sensory attributes. Hardness and springiness were both accurately predicted by rheologic properties, while cohesiveness prediction was less representative. PRACTICAL APPLICATIONS This study contributes to enhance the knowledge in the research area of sensory instrumental correlation. Also, the research allows to better understanding that no single instrument is able to measure all texture attributes adequately. In fact, the results demonstrate that both stress,relaxation and cyclic compression tests need to be performed for the correct prediction of sensory responses. [source]

CRISPY/CRUNCHY CRUSTS OF CELLULAR SOLID FOODS: A LITERATURE REVIEW WITH DISCUSSION

JOURNAL OF TEXTURE STUDIES, Issue 5 2004
HANNEMIEKE LUYTEN
ABSTRACT Literature on the crispy/crunchy behavior of cellular solid foods with a crust is discussed. The emphasis is on products with a dry crispy or crunchy crust as bread and various snacks and especially on mesoscopic and macroscopic aspects. Successively, the sensory sensations involved, the mechanical and fracture behavior of crispy/crunchy products, morphological aspects, and the relation between crispy and crunchy behavior and mobility of the macromolecules and plasticizer (primarily water) involved, are discussed. Finally, some ideas for an integrated approach of crispy/crunchy behavior of cellular solid foods with a dry crust will be discussed. [source]

Patterns in current anaesthesiological peri-operative practice for colonic resections: a survey in five northern-European countries

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2006
P. Hannemann
Background:, For colorectal surgery, evidence suggests that optimal management includes: no pre-operative fasting, a thoracic epidural analgesia continued for 2 days post-operatively, and avoidance of fluid overload. In addition, no long-acting benzodiazepines on the day of surgery and use of short-acting anaesthetic medication may be beneficial. We examined whether these strategies have been adopted in five northern-European countries. Methods:, In 2003, a questionnaire concerning peri-operative anaesthetic routines in elective, open colonic cancer resection was sent to the chief anaesthesiologist in 258 digestive surgical centres in Scotland, the Netherlands, Denmark, Sweden and Norway. Results:, The response rate was 74% (n = 191). Although periods of pre-operative fasting up to 48 h were reported, most (> 85%) responders in all countries declared to adhere to guidelines for pre-operative fasting and oral clear liquids were permitted until 2,3 h before anaesthesia. Solid food was permitted up to 6,8 h prior to anaesthesia. In all countries more than 85% of the responders indicated that epidural anaesthesia was routinely used. Except for Denmark, long-acting benzodiazepines were still widely used. Short-acting anaesthetics were used in all countries except Scotland where isoflurane is the anaesthetic of choice. With the exception of Denmark, intravenous fluids were used unrestrictedly. Conclusion:, In northern Europe, most anaesthesiologists adhere to evidence-based optimal management strategies on pre-operative fasting, thoracic epidurals and short-acting anaesthetics. However, premedication with longer-acting agents is still common. Avoidance of fluid overload has not yet found its way into daily practice. This may leave patients undergoing elective colonic surgery at risk of oversedation and excessive fluid administration with potential adverse effects on surgical outcome. [source]

Introduction of solids and formula to breastfed infants: a longitudinal prospective study in Uppsala, Sweden

ACTA PAEDIATRICA, Issue 5 2001
A Hörnell
The introduction of solids and formula was studied among 506 breastfed infants in Uppsala, Sweden, based on daily recordings during the first year. The mothers had previously breastfed at least 1 infant for at least 4 mo. Thirty-four per cent of the infants were introduced to solids before the age of 4 mo (4,6 mo is recommended in Sweden). Accustoming the infants to solids was a lengthy process. Life-table analyses showed a median duration of 28 d from the first introduction of solids to consumption of >10 ml daily, and 46 d before the infants ate 100 ml of solids in 1 d for the first time. These durations were longer the younger the infant was at the introduction of solids. Thirty-two per cent of infants given formula consumed 100 ml the first time it was given, and 49% did so within 1 wk, regardless of infant age. Conclusion: Parents and healthcare personnel need to be aware that accustoming breastfed infants to solid food is a lengthy process, and that there is a strong age effect on this duration. It is also important to consider what consequences the (usually) more abrupt introduction of formula might have on breastfeeding. [source]

The feeding behavior of Trichogramma brassicae: new evidence for selective ingestion of solid food

ENTOMOLOGIA EXPERIMENTALIS ET APPLICATA, Issue 1 2000
Z.X. Wu
Abstract A descriptive study of the feeding behavior and structures of Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) was conducted. Based on direct observational and biochemical evidence, larvae feed predominantly on particulate materials, starting ca. 25 h post-oviposition. Feeding lasted for ca. 9 h, at 25±1 °C. During this feeding period the shape of the larvae changed from vermiform to pyriform and then to sacciform, resulting in a ca. 40-fold increase in body size. Larvae used elaborate feeding behaviors as they pulled solid food particles to their oral opening, broke small particles from larger ones, and took the particles into the stomodaeum, which is a powerful pump. In the stomodaeum, peristaltic movement further macerated the particles, which eventually passed through the cardiac valve into the midgut. As indicated by changes in fluorescently labeled casein, digestive enzymes aid in the extra-oral chemical digestion of food. The contents of the gut, during and shortly after feeding, were almost entirely closely packed solid particles. The behavioral activity of feeding larvae centered almost exclusively on processing and ingesting solid food particles. The rapid larval growth is much more plausibly explained by their feeding on the highly concentrated nutrients found in solid foods, rather than the extensive concentration required if dilute liquids were the principal source of nutrients. The implications of these findings for the development of practical artificial diets are discussed. [source]

Pre-operative fasting: a nationwide survey of German anaesthesia departments

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2010
J.-P. BREUER
Background: Shorter pre-operative fasting improves clinical outcome without an increased risk. Since October 2004, German Anaesthesiology Societies have officially recommended a fast of 2 h for clear fluids and 6 h for solid food before elective surgery. We conducted a nationwide survey to evaluate the current clinical practice in Germany. Methods: Between July 2006 and January 2007, standardized questionnaires were mailed to 3751 Anaesthesiology Society members in leading positions requesting anonymous response. Results: The overall response rate was 66% (n=2418). Of those, 2148 (92%) claimed familiarity with the new guidelines. About a third (n=806, 34%) reported full adherence to the new recommendations, whereas 1043 (45%) reported an eased fasting practice. Traditional Nil per os after midnight was still recommended by 157 (7%). Commonest reasons reported for adopting the new guidelines were: ,improved pre-operative comfort' (84%), and ,increased patient satisfaction' (83%); reasons against were: ,low flexibility in operation room management' (19%), and ,increased risk of aspiration' (13%). Conclusion: Despite the apparent understanding of the benefits from reduced pre-operative fasting, full implementation of the guidelines remains poor in German anaesthesiology departments. [source]

ORIGINAL ARTICLE: Description of development of rumen ecosystem by PCR assay in milk-fed, weaned and finished lambs in an intensive fattening system

JOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 5 2010
A. Belanche
Summary This study examined the reticulo-rumen characteristics of the microbial community and its fermentative characteristics in milk-fed, at weaning and finished lambs in a conventional fattening system. Five lambs were assigned to each of three groups: milk-fed lambs slaughtered at 30 days (T30), weaned lambs slaughtered at 45 days (T45) and ,finished lambs' slaughtered at 90 days (T90). At slaughter, rumen size, fermentation parameters (pH, volatile fatty acids and microbial enzyme activity) and protozoal counts were recorded. Quantitative PCR was used to quantify the genes encoding 16S and 18S ribosomal DNA of the rumen bacterial and protozoal populations, respectively, and the sequential colonization of the rumen by cellulolytic (Ruminococcus albus, Ruminococcus flavefaciens) and amylolytic (Prevotella ruminicola, Streptococcus bovis) bacteria, and protozoa (Entodinium sp.). Denaturing gradient gel electrophoresis was used to study the development of rumen microbiota biodiversity. Intake of solid food before weaning caused a significant increase in rumen weight (p < 0.0001) and bacterial DNA (p < 0.05) and volatile fatty acid analysis concentration (p < 0.01), whereas pH declined. In milk-fed lambs, cellulolytic bacteria were evident after 30 days. Thereafter, in the 45-day and 90-day groups, the proportions of R. flavefaciens decreased and R. albus increased. Amylolytic bacteria were present in milk-fed lambs; the proportion of P. ruminicola increased in fattening lambs and S. bovis was the least abundant species. Protozoal concentrations were irregular; milk-fed lambs had a significant number of protozoa species from Entodinium and subfamily Isotrichiidae, but they disappeared at weaning. Lamb rumen were refaunated in some individuals at 90 days (Entodinium and subfamily Diplodiniinae spp.), although individual concentrations were variable. [source]

Life-style Correlates of Tooth Loss in an Adult Midwestern Population

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 3 2004
Barbara E. K. Klein MD
Abstract Objectives: To describe life-style correlates of tooth loss in a representative rural American population. Methods: Information on tooth loss as well as past medical history and life-style factors was obtained in a well-defined cohort of 2,764 persons 53,96 years of age in Beaver Dam, WI (1998,2000). Results: There were 1,992 (68.2%) persons missing some and 447 (15.3%) missing all of their teeth. In univariable analyses, age, cigarette smoking, heavy drinking, education, multivitamin use, and diabetes status were associated with tooth loss. Tooth loss was associated with poorer self-rated health and with difficulty eating solid food and inability to enjoy some food. In multivariable models age, education, smoking, heavy drinking, and diabetes were significantly associated with tooth loss. Conclusions: Tooth loss is common in older persons and is associated with many risk factors including education, smoking, and heavy drinking. It is possible that modifying these may influence risk of tooth loss. [source]

Acrylamide levels in Finnish foodstuffs analysed with liquid chromatography tandem mass spectrometry

MOLECULAR NUTRITION & FOOD RESEARCH (FORMERLY NAHRUNG/FOOD), Issue 2 2007
Susanna Eerola
Abstract Sample clean-up and HPLC with tandem mass spectrometric detection (LC-MS/MS) was validated for the routine analysis of acrylamide in various foodstuffs. The method used proved to be reliable and the detection limit for routine monitoring was sensitive enough for foods and drinks (38 ,g/kg for foods and 5 ,g/L for drinks). The RSDs for repeatability and day-to-day variation were below 15% in all food matrices. Two hundred and one samples which included more than 30 different types of food and foods manufactured and prepared in various ways were analysed. The main types of food analysed were potato and cereal-based foods, processed foods (pizza, minced beef meat, meat balls, chicken nuggets, potato-ham casserole and fried bacon) and coffee. Acrylamide was detected at levels, ranging from nondetectable to 1480 ,g/kg level in solid food, with crisp bread exhibiting the highest levels. In drinks, the highest value (29 ,g/L) was found in regular coffee drinks. [source]

Dietary prevention of allergic diseases in infants and small children

PEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 1 2008
Amendment to previous published articles in Pediatric Allergy, Clinical Immunology, European Academy of Allergology, Immunology 200, by an expert group set up by the Section on Pediatrics
Because of scientific fraud four trials have been excluded from the original Cochrane meta-analysis on formulas containing hydrolyzed protein for prevention of allergy and food intolerance in infants. Unlike the conclusions of the revised Cochrane review the export group set up by the Section on Paediatrics, European Academy of Allergology and Clinical Immunology (SP-EAACI) do not find that the exclusion of the four trials demands a change of the previous recommendations regarding primary dietary prevention of allergic diseases. Ideally, recommendations on primary dietary prevention should be based only on the results of randomized and quasi-randomized trials (selection criteria in the Cochrane review). However, regarding breastfeeding randomization is unethical, Therefore, in the development of recommendations on dietary primary prevention, high-quality systematic reviews of high-quality cohort studies should be included in the evidence base. The study type combined with assessment of the methodological quality determines the level of evidence. In view of some methodological concerns in the Cochrane meta-analysis, particularly regarding definitions and diagnostic criteria for outcome measures and inclusion of non peer-reviewed studies/reports, a revision of the Cochrane analysis may seem warranted. Based on analysis of published peer-reviewed observational and interventional studies the results still indicate that breastfeeding is highly recommended for all infants irrespective of atopic heredity. A dietary regimen is effective in the prevention of allergic diseases in high-risk infants, particularly in early infancy regarding food allergy and eczema. The most effective dietary regimen is exclusively breastfeeding for at least 4,6 months or, in absence of breast milk, formulas with documented reduced allergenicity for at least the first 4 months, combined with avoidance of solid food and cow's milk for the first 4 months.

Begging for information: mother,offspring food sharing among wild Bornean orangutans

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 6 2008
Adrian V. Jaeggi
Abstract Transfer of solid food from mothers or other adults to dependent offspring is commonly observed in various primate species and both nutritional and informational benefits have been proposed to explain the function of such food sharing. Predictions from these hypotheses are tested using observational data on wild orangutans (Pongo pygmaeus wurmbii) at Tuanan, Central Borneo, Indonesia. In 1,145,hr of focal observation and 458 recorded food interactions between four pairs of females with offspring it was found that virtually all transfers were initiated by the offspring and that younger infants solicited food more often and did so for a greater variety of items than older offspring. All offspring primarily solicited food that was difficult to process, i.e., inaccessible to them. Furthermore, the amount of food solicitation was negatively correlated with ecological competence. Hence food sharing seemed to be related to an offspring's skill level, as suggested by the informational hypothesis. In contrast, offspring did not solicit high-quality items more than low-quality items and food sharing did not peak around the age of weaning, as predicted by the nutritional hypothesis. Mothers were usually passively tolerant, allowing offspring to take food but hardly ever provisioned. Parent,offspring conflict concerning food sharing was only observed well after weaning. Thus, by taking food directly from the mother, young orangutans were able to obtain information about the affordances and nutritional value of food items that were otherwise out of their reach and could familiarize themselves with the mother's diet. In species such as orangutans or other apes, characterized by a broad diet that requires extractive foraging, informational food transfer may be vital for an immature to acquire complex feeding skills and adult diet.

Superior palatability of crushed lercanidipine compared with amlodipine among children

BRITISH JOURNAL OF CLINICAL PHARMACOLOGY, Issue 2 2010
Gregorio Milani
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT , Among children, medication palatability is crucial for adherence to therapeutic regimen. , Since there is a lack of appropriate formulations for children prescribed drugs originally designed for adults, parents crush available tablets and administer the medication mixed with solid food or a palatable drink. , Crushed amlodipine, a very popular calcium channel blocker, is bitter and unpalatable. WHAT THIS STUDY ADDS , From the perspective of the child with arterial hypertension, the taste of pulverized lercanidipine is superior to that of pulverized amlodipine. AIMS To compare the taste of equivalent doses of pulverized amlodipine and lercanidipine, two calcium channel blockers, among children with kidney disease. METHODS Each child received a test dose of 1 mg of amlodipine besylate and 2 mg of lercanidipine in a single-blinded fashion. Children indicated their preference by pointing to the appropriate face on a visual analogue scale (VAS) that depicts five degrees of pleasure. RESULTS The VAS palatability score assigned to lercanidipine was higher than that assigned to amlodipine both in nine children 4,7 years of age (P < 0.005) and in 10 children 8,11 years of age (P < 0.005). The preference for lercanidipine was statistically significant in both girls (P < 0.02) and boys (P < 0.001) and in both children initially presented amlodipine (P < 0.005) and children initially presented lercanidipine (P < 0.005). CONCLUSIONS There is a lack of appropriate formulations for children prescribed drugs originally designed for adults, such as calcium channel blockers. Parents therefore crush available tablets and administer the medication mixed with solid food or a palatable drink. From the perspective of the child, the taste of pulverized lercanidipine is superior to that of pulverized amlodipine. [source]

Five-year follow-up of a randomized clinical trial of laparoscopic total versus anterior 180° fundoplication

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 2 2005
R. Ludemann
Background: Total fundoplication for gastro-oesophageal reflux disease may be followed by unwanted side-effects. A randomized trial demonstrated that an anterior 180° partial fundoplication achieved effective reflux control and was associated with fewer side-effects in the short term than total fundoplication. This paper reports longer-term (5 year) outcomes from that trial. Methods: Between December 1995 and June 1997, 107 patients were randomized to undergo either laparoscopic total fundoplication or a laparoscopic anterior 180° fundoplication. After 5 years, 101 of 103 eligible patients (51 total, 50 anterior) were available for follow-up. Each patient was interviewed by a single blinded investigator and a standardized questionnaire was completed. The questionnaire focused on symptoms and overall satisfaction with the results of fundoplication. Results: There were no significant differences between the two groups with regard to control of heartburn or patient satisfaction with the overall outcome. Dysphagia, measured by a visual analogue score for solid food and a composite dysphagia score, was worse at 5 years after total fundoplication. Symptoms of bloating, inability to belch and flatulence were also more common after total fundoplication. Reoperation was required for dysphagia in three patients after total fundoplication and for recurrent reflux in three patients after anterior fundoplication. Conclusion: Anterior 180° partial fundoplication was as effective as total fundoplication for managing the symptoms of gastro-oesophageal reflux in the longer term. It was associated with a lower incidence of side-effects, although this was offset by a slightly higher risk of recurrent reflux symptoms. Copyright © 2004 British Journal of Surgery Society Ltd.

The feeding behavior of Trichogramma brassicae: new evidence for selective ingestion of solid food

Palliation in cancer of the oesophagus , what passes down an oesophageal stent?

JOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 5 2003
A. Holdoway
Introduction: Self-expanding metal stents are becoming an increasingly popular method of palliation of dysphagia in advanced oesophageal carcinoma. Approximately 10% require intervention post-placement because of blockage (Angorn, 1981). This could be prevented by effective dietary advice. We set out to write evidence-based dietary guidelines for patients undergoing oesophageal stent insertion. A comprehensive literature search failed to identify evidence to support the present guidelines used by manufacturers and dietitians on foods allowed or to avoid and the use of fizzy drinks to ,clean' the stent. Only reference on the ability to consume a semi-solid or solid diet was made (Nedin, 2002). We therefore tested the ability of 50 foods to pass through a stent and the efficacy of fizzy water in unblocking an occluded stent. Method: Normal mouthfuls of raw and cooked, peeled/unpeeled fruit and vegetables, casseroles, griddle or grilled plain meat, poultry or fish, eggs, nuts, dried fruit and bread in various forms were tested. An adult female chewed a ,normal' mouthful of each test food and at the point of swallowing the bolus of food was passed into an expanded Ultraflex metal covered stent (internal diameter 18 mm). If occlusion occurred, water was dribbled through the stent, simulating swallowing fluid, in an attempt to unblock the stent. If the occlusion remained, the stent was agitated to mimic advice given about moving around to unblock a stent in a patient. If it remained occluded, a smaller amount of food, approximately half a mouthful, was chewed for twice as long and re-tested. To test the efficacy of fizzy water to clear an occlusion, we compared the ability of water, warm water and fizzy water to unblock a stent artificially occluded with a bolus of bread. Results: Foods that occluded the stent but passed through if eaten in half mouthfuls and chewed for twice normal chewing time included sandwiches, dry toast, apple, tinned pineapple, fresh orange segments with pith removed, up to six sultanas, chopped dried apricot, boiled egg, muesli, meat and poultry. Dry meat, fruit with pith, skins of capsicum peppers and tomatoes, more than seven sultanas and dried apricots caused occlusion. Nuts and vegetables such as lettuce, which are cited in many diet sheets as items to avoid (Nedin, 2002), passed through the stent when chewed to a normal level. The volumes of fluid required to unblock a stent occluded with bread were 5 l of fizzy water, 3.5 l of cold water or 1 l of warm water. Conclusion: If a patient has good dentition and can chew well and take small mouthfuls and prepare and cook food appropriately, it is likely that they can enjoy a wide variety of solid foods. The use of fizzy drinks to maintain the patency of the stent in patients prone to reflux is questionable, warm fluids may be more efficacious. Based on these initial findings we are updating our dietary guidelines for patients undergoing oesophageal stent insertion and hope to audit stent occlusion following implementation. [source]

Sources of Dietary Fluoride Intake in 6,7-Year-Old English Children Receiving Optimally, Sub-optimally, and Non-fluoridated water

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 4 2006
Fatemeh V. Zohouri BSc, RPHNutr
Abstract Objectives:Due to increased consumption of pre-packaged drinks, tap water may no longer be the principal source of water intake and consequently fluoride intake. Little is known about the importance of solid foods as fluoride sources and how the relative contribution of foods/drinks to fluoride intake is affected by residing in fluoridated or non-fluoridated areas. This study investigated the relative contributions of different dietary sources to dietary fluoride intake and compared this in children residing in optimally artificially fluoridated, sub-optimally artificially fluoridated, and non-fluoridated areas. Methods:Thirty-three healthy children aged 6 years were recruited from fluoridated and non-fluoridated communities and categorised into three groups based on fluoride content of home tap water: optimally fluoridated (<0.7 mgF/L), sub-optimally fluoridated (>0.3 to <0.7 mgF/L) and non-fluoridated (<0.3 mgF/L) drinking water. A 3-day dietary diary collected dietary information. Samples of foods/drinks consumed were collected and analyzed for fluoride content. Results:Drinks provided 59%, 55% and 32% of dietary fluoride intake in optimally, sub-optimally and non-fluoridated areas respectively. Tap water, fruit squashes and cordials (extremely sweet non-alcoholic fruit flavoured drink concentrates) prepared with tap water, as well as cooked rice, pasta and vegetables were important sources of fluoride in optimally and sub-optimally fluoridated areas. Carbonated soft drinks and bread were the most important contributors to dietary fluoride intake in the non-fluoridated area. Conclusion:The main contributory sources to dietary fluoride differ between fluoridated and non-fluoridated areas. Estimating total fluoride intake from levels of fluoride in tap water alone is unlikely to provide a reliable quantitative measure of intake. Studies monitoring dietary fluoride exposure should consider intake from all foods and drinks. [source]

CRISPY/CRUNCHY CRUSTS OF CELLULAR SOLID FOODS: A LITERATURE REVIEW WITH DISCUSSION

Immunoglobulins in saliva of preterm and full-term infants.

MOLECULAR ORAL MICROBIOLOGY, Issue 2 2003
18 months of age, A longitudinal study from 0
The aim of this longitudinal study was to determine salivary levels of total IgA, IgG and IgM in 84 preterm and 214 full-term infants, from birth to 18 months of age. Unstimulated whole saliva was collected from each infant at birth, and subsequently at 3-monthly intervals. Immunoglobulin levels were estimated using an ELISA technique. At birth, IgA was detected in 147/214 (69%) full-term infants but only 47/84 (56%) preterm infants (P < 0.01). In the case of IgG, 61% of full-term and 56% of preterm infants showed detectable levels, whereas IgM was found in 71% and 73%, respectively. Levels of IgA and IgG rose from birth to 18 months, whereas IgM levels did not change significantly. Increases in salivary levels of IgA were associated with introduction of solid foods (P < 0.001), as well as tooth eruption (P < 0.001). Our results indicate that the majority of full-term and preterm infants are orally immunocompetent at birth. [source]

Feeding behavior of lactating brown lemur females (Eulemur fulvus) in Mayotte: influence of infant age and plant phenology

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 10 2006
Laurent Tarnaud
Abstract Altmann [Baboon Mothers and Infants, University of Chicago Press, 1980] and Dunbar and Dunbar [Animal Behavior 36:970,980, 1988] provided a model that predicts the amount of time spent feeding by lactating baboon females, as related to infant age. Dunbar's model further suggests that food quality affects the amount of time that females devote to feeding activity, and is predictable from rainfall and temperature data. In this study the model was tested with data recorded from births of the Mayotte brown lemur from four maternal dyads (Eulemur fulvus). This study also examines the correlation between female activity budget, quantities of fresh plant matter ingested, and suckling duration using data collected from focal animal samples on the mother,infant dyads. The relationships among rainfall, food supply, and food quality were also tested. It appears that female brown lemurs do not devote more time to feeding during the infant growth period. The data show that female brown lemurs increased their food intake during the early-lactating period when the frequency of suckling is the highest, and before infants begin to eat substantial amounts of solid foods. Thus, the frequency of feeding reflects the cost of lactation better than suckling duration. Furthermore, females did not appear to select foods according to their availability or rainfall levels. I hypothesize that the lack of convergence between lemur data and baboon observations is due to differences between their respective environments and their feeding ecology. These data also indicate that the most significant lactating cost for the brown lemur occurs during the early lactation period. Am. J. Primatol. 68:1,12, 2006. © 2006 Wiley-Liss, Inc. [source]

Feeding practices of infants through the first year of life in Italy

ACTA PAEDIATRICA, Issue 4 2004
M Giovannini
Aim: To investigate infant feeding practices through the first year of life in Italy, and to identify factors associated with the duration of breastfeeding and early introduction of solid foods. Methods: Structured phone interviews on feeding practices were conducted with 2450 Italian-speaking mothers randomly selected among women who delivered a healthy-term singleton infant in November 1999 in Italy. Interviews were performed 30 d after delivery and when the infants were aged 3, 6, 9 and 12 mo. Type of breastfeeding was classified according to the WHO criteria. Results: Breastfeeding started in 91.1% of infants. At the age of 6 and 12mo, respectively, 46.8% and 11.8% of the infants was still breastfed, 68.4% and 27.7% received formula, and 18.3% and 65.2% were given cow's milk. Solids were introduced at the mean age of 4.3 mo (range 1.6,6.5 mo). Introduction of solids occurred before age 3 and 4 mo in 5.6% and 34.2% of infants, respectively. The first solids introduced were fruit (73.1%) and cereals (63.9%). The main factors (negatively) associated with the duration of breastfeeding were pacifier use (p > 0.0001), early introduction of formula (p > 0.0001), lower mother's age (p > 0.01) and early introduction of solids (p= 0.05). Factors (negatively) associated with the introduction of solids foods before the age of 3 mo were mother not having breastfed (p > 0.01), early introduction of formula (p > 0.01), lower infant bodyweight at the age of 1 mo (p= 0.05) and mother smoking (p= 0.05). Conclusion: The duration of breastfeeding in Italy is still inadequate, as well as compliance with international recommendations for timing of introduction of complementary foods. National guidelines, public messages and educational campaigns should be promoted in Italy. [source]

Patterns of breastfeeding in a UK longitudinal cohort study

MATERNAL & CHILD NUTRITION, Issue 1 2007
David Pontin
Abstract Although exclusive breastfeeding for the first 6 months of infant life is recommended in the UK, there is little information on the extent of exclusive breastfeeding. This study has taken the 1996 and 2003 World Health Organization (WHO) definitions of breastfeeding and investigated breastfeeding rates in the first 6 months of life in infants born to mothers enrolled in a longitudinal, representative, population-based cohort study , the Avon Longitudinal Study of Parents and Children (ALSPAC). Information about breastfeeding and introduction of solids was available for 11 490 infants at 6 months of age (81% of live births). Exclusive breastfeeding declined steadily from 54.8% in the first month to 31% in the third, and fell to 9.6% in the fourth month mainly due to the introduction of solids to the infants. In the first 2 months, complementary feeding (breastmilk and solid/semi-solid foods with any liquid including non-human milk) was used in combination, and declined from 22% in the first month to 16.8% in the second due to a switch to exclusive commercial infant formula feeding. Replacement feeding (exclusive commercial infant formula or combined with any liquid or solid/semi-solid food but excluding breastmilk) increased steadily from 21.9% in the first month to 67.1% by the seventh. This obscured the change from exclusive commercial infant formula feeding only to commercial infant formula feeding plus solids/semi-solids, a change which started in the third month and was complete by the fifth. Using categories in the 1996 and 2003 WHO definitions, such as complementary feeding and replacement feeding, presented difficulties for an analysis of the extent of breastfeeding in this population.
