Animal- and plant-food-based diets and iron status: benefits and costsProceedings of the Nutrition Society - Tập 58 Số 2 - Trang 235-242 - 1999
Leif Hambræus
Fe seems to be the only nutrient deficiency that industrialized and low-income
countries have in common. Thus, Fe is one of the most critical nutrition
requirements to be met in most diets in human subjects. Fe deficiency is caused
not only by too low an intake, but is also the result of low bioavailability, as
well as an increased Fe requirement due to physiological variables or clinical
problems... hiện toàn bộ
Regulation of bone cell function by acid–base balanceProceedings of the Nutrition Society - Tập 62 Số 2 - Trang 511-520 - 2003
T Arnett
Bone growth and turnover results from the coordinated activities of two key cell
types. Bone matrix is deposited and mineralised by osteoblasts and it is
resorbed by osteoclasts, multinucleate cells that excavate pits on bone
surfaces. It has been known since the early 20th century that systemic acidosis
causes depletion of the skeleton, an effect assumed to result from
physico-chemical dissolutio... hiện toàn bộ
Biochemistry of plant secondary metabolites and their effects in animalsProceedings of the Nutrition Society - Tập 64 Số 3 - Trang 403-412 - 2005
T. Acamovic, J.D. Brooker
Plant secondary metabolites, which include a wide variety of phytochemicals,
have always been constituents of the diets of man and other animals. Although a
high proportion of these phytochemicals have been considered to be of little
value in plants (although this view is changing), they have frequently been
shown to have adverse effects on animals when ingested. The effects depend to a
great exte... hiện toàn bộ
Hypothalamic dysfunction in obesityProceedings of the Nutrition Society - Tập 71 Số 4 - Trang 521-533 - 2012
Lynda M. Williams
A growing number of studies have shown that a diet high in long chain SFA and/or
obesity cause profound changes to the energy balance centres of the hypothalamus
which results in the loss of central leptin and insulin sensitivity.
Insensitivity to these important anorexigenic messengers of nutritional status
perpetuates the development of both obesity and peripheral insulin
insensitivity. A high-f... hiện toàn bộ
Folate and vitamin B12Proceedings of the Nutrition Society - Tập 58 Số 2 - Trang 441-448 - 1999
John M. Scott
The folates are made up of a pterdine ring attached to a p-aminobenzoate and a
polyglutamyl chain. The active form is tetrahydrofolate which can have C1 units
enzymically attached. These C1 units (as a formyl group) are passed on to
enzymes in the purine pathway that insert the C−2 and C−8 into the purine ring.
A methylene group (−CH2−) attached to tetrahydrofolate is used to convert the
uracil-ty... hiện toàn bộ
Session 1: Feeding and infant development Breast-feeding and immune functionProceedings of the Nutrition Society - Tập 66 Số 3 - Trang 384-396 - 2007
Lars Hanson
The newborn receives, via the placenta, maternal IgG antibodies against the
microbes present in its surroundings, but such antibodies have a
pro-inflammatory action, initiating the complement system and phagocytes.
Although the host defence mechanisms of the neonate that involve inflammatory
reactivity are somewhat inefficient, this defence system can still have
catabolic effects. Breast-feeding c... hiện toàn bộ
Nutritional management of gut health in pigs around weaningProceedings of the Nutrition Society - Tập 66 Số 2 - Trang 260-268 - 2007
Jean Paul Lallès, Paolo Bosi, Hauke Smidt, Chris R. Stokes
Early weaning of piglets is often accompanied by a severe growth check and
diarrhoea. It is well established that this process is multi-factorial and that
post-weaning anorexia and undernutrition are major aetiological factors.
Gastrointestinal disturbances include alterations in small intestine
architecture and enzyme activities. Recent data indicate transiently-increased
mucosal permeability, di... hiện toàn bộ
Review of statutory and voluntary labelling of food allergensProceedings of the Nutrition Society - Tập 64 Số 4 - Trang 475-480 - 2005
Mark Boden, Ruth Dadswell, Sue Hattersley
Food allergy represents an increasingly important health problem, with
prevalence in Western Europe continuing to rise. While some reactions are mild,
others can include life-threatening anaphylactic shock. It is estimated that
food allergies affect 1–2% of the adult population and ≤8% of children.
Relatively few foods are to blame for a large majority of allergic reactions to
food in the UK, with... hiện toàn bộ
