The potential link between episodes of diverticulitis or hemorrhoidal proctitis and diets with selected plant foods : a case-control study
2021
Diverticulitis and hemorrhoidal proctitis in the population are significant public health problems. We studied the potential association between the intake of certain plant foods and diverticulitis or hemorrhoidal episodes through a case–control study including 410 cases and 401 controls. We used a semiquantitative food frequency questionnaire. The intake was additionally quantified according to a 24 h recall. The plant foods or derived food products were categorized by their main chemical components into ethanol, caffeine/theine/theobromine, capsaicin, alliin, acids, eugenol, and miscellaneous foods such as curcumin. The mean score for overall intake of plant foods under consideration was …

Effect of low levels of dietary fish oil on fatty acid desaturation and tissue fatty acids in obese and lean rats
1995
The effect of very low levels of dietary long-chain n-3 fatty acids on delta 6 desaturation of linoleic acid (18:2n-6) and alpha-linolenic acid (18:3n-3), and on delta 5 desaturation of dihomo-gamma-linolenic acid (20:3n-6), in liver microsomes and its influence on tissue fatty acids were examined in obese and lean Zucker rats and in Wistar rats. Animals fed for 12 wk a balanced diet containing ca. 200 mg of long-chain polyunsaturated n-3 fatty acids per 100 g of diet were compared to those fed the same amount of alpha-linolenic acid. Low amounts of long-chain n-3 fatty acids greatly inhibited delta 6 desaturation of 18:2n-6 and delta 5 desaturation of 20:3n-6, while delta 6 desaturation of…
Low-protein diet prevents tissue lipoprotein lipase activity increase in growing rats
2000
The time course of changes in tissue lipolytic activities was studied in young rats during theconsumption of a low-protein diet containing 50 g protein/kg (40 g wheat gluten +10 g casein/kg) for 28 d followed by balanced refeeding with 200 g protein/kg (160 g wheat gluten +40 gcasein/kg) for 28 d. Lipoprotein lipase (LPL) activities were compared with the values of acontrol group fed a balanced diet containing 200 g protein/kg for 56 d. At the end of proteinmalnutrition period, the epididymal fat tissue LPL activity represented 36 %, and that of heartand gastrocnemius was 44 %, of those of the control group. These differences wereaccompanied by lower serum- and VLDL-triacylglycerols (TAG), …
Lipid content and essential fatty acid (EFA) composition of mature Congolese breast milk are influenced by mothers' nutritional status: Impact on inf…
1998
To measure the lipid content and the fatty acid (FA) composition of breast milk as part of a nutritional survey of the essential fatty acid (EFA) status of 5 months old Congolese infants.Cross sectional nutrition survey.A suburban district of Brazzaville (capital of the Congo).A random sample of nursing mothers and their 5 months old infants (n = 102). Data collection procedures: The mothers were questioned on their socio-economic status, dietary habits, and their body mass index (BMI) was measured. Breast milk samples were collected from each mother. Milk lipid content and fatty acid composition were determined.Compared with milk from various countries, Congolese women's mature breast milk…
Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight
2021
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia…
Iron Fortification of Milk and Dairy Products
2013
Blood haemoglobin level is used to define anaemia. Thresholds are given by category of age, of sex, and also of physiological status such as pregnancy. For example, the threshold is 120 g L–1 of haemoglobin in blood for a nonpregnant adult woman, 110 for a pregnant woman, 130 for a man older than 15 years, 110 for a child under 5 years… Iron deficiency constitutes the most important worldwide problem of human nutrition. In 2005, 1.62 billions of people were concerned by iron deficiency. Iron deficiency is encountered mostly in poor countries and particularly in Western Pacific, except Australia and New Zealand, in India and Pakistan, in the great majority of countries in Africa, in South Am…
Promoting Food Waste Reduction at Primary Schools. A Case Study
2021
Food waste (FW) has recently attracted the interest of different institutions and has been the focus of many studies due to its important environmental, social and economic impact. This paper aims to analyze whether a didactic intervention, consisting of informing teachers and pupils and involving pupils in reducing FW, could bring about changes in the level of knowledge and attitude towards FW and in the amount of FW generated during the mid-morning break and lunch at schools. This study was conducted at a public Primary School in Valencia (Spain). Subtle changes in the level of knowledge and attitude towards FW were detected in teachers and pupils after the intervention. Around 30% of FW …
Temari Parasitologia alimentària Grau en Nutrició Humana i Dietètica
2013
Presentacions de l´assignatura lliçó per lliçó L'assignatura Parasitologia alimentària (33950) és una matèria de caràcter obligatori de tercer curs del grau en Nutrició Humana i Dietètica, que s'imparteix en la Facultat de Farmàcia de la Universitat de València. En l'actual pla d'estudis disposa de 6 crèdits ECTS amb caràcter semestral. Les parasitosis, sobretot les intestinals, tenen un efecte negatiu sobre el desenvolupament cognitiu i físic de les persones que s'associen a manques nutricionals, especialment de ferro i vitamina A. El binomi paràsit-malnutrició és el més important, comú i persistent problema de salut dels països en desenvolupament. L'objectiu fonamental és mostrar als estu…
