This includes factors such as the quantity, quality, timing and nutrient components of every meal. Physical maturation follows the same course for all children, although rates will differ between individuals. Post-natal growth spans three age periods: infancy , which is the first year of life; childhood , which extends from infancy to around 10 years of age; and adolescence , which is defined as between 10 and 18 years of age.
Brain development in humans is remarkably resistant to permanent damage from protein-energy malnutrition. However, specific nutrients have crucial roles. Iodine deficiency is the most important and widespread nutrient deficiency; it causes endemic cretinism, associated with deaf-mutism and cerebral palsy. Iodine deficiency during pregnancy causes both maternal and fetal hypothyroxinemia, resulting in irreversible impairment of brain development at a critical stage. Neuropathological data place this after 14 wk, perhaps continuing through the third trimester. Gross brain structure, including the gyral pattern of the cerebral cortex, develops normally; the insult affects neuron and dendrite growth. Recent magnetic-resonance-imaging MRI images of neurological cretin brains show remarkably normal appearance except for gliotic lesions of the globus pallidus, correlating with the proximal motor rigidity seen clinically.

Here we will look at the short-term effects of what children eat then at the longer term influence of certain dietary choices. Fourteen percent of UK school children skip breakfast, with this being more likely in the case of secondary school children and in areas of deprivation [i].

During the first years, toddlers acquire particular cognitive and motor skills. Their spoken vocabulary increases significantly, they gain greater motor coordination and they become able to concentrate on tasks for slightly longer periods. Among those environmental determinants, visual and sound stimulation contribute importantly to the development of neural circuits. Understanding the role of some key nutrients involved in the brain neural development of toddlers, the European food safety authority EFSA has approved certain health claims related to those nutrients Table 1.

Summary of review 1. What we know : It is likely that nutrition deficiency during pregnancy and early childhood affects individual cognition, behaviour, long term productivity and also negatively impacts economic development. What this article adds : Severe acute malnutrition, chronic undernutrition intrauterine growth retardation and stunting , iron deficiency anaemia and iodine deficiency are key risk factors for poor motor, cognitive, and socio-emotional development and should be a global priority. Effective strategies to address these forms of undernutrition exist; the evidence for impact of other forms of undernutrition on brain development is lacking. Robust research to evaluate interventions in low and middle income countries is needed. Adequate nutrition is necessary for normal brain development. Nutrition is especially important during pregnancy and infancy, which are crucial periods for the formation of the brain, laying the foundation for the development of cognitive, motor, and socio-emotional skills throughout childhood and adulthood.
See our Coronavirus resources for early childhood professionals. Parenting Resource. Brain development is most sensitive to a baby's nutrition between mid-gestation and two years of age. Children who are malnourished—not just fussy eaters but truly deprived of adequate calories and protein in their diet—throughout this period do not adequately grow, either physically or mentally. Their brains are smaller than normal because of reduced dendritic growth, reduced myelination, and the production of fewer glia supporting cells in the brain which continue to form after birth and are responsible for producing myelin.
Nutrition has been called the single greatest environmental influence on babies in the womb and during infancy 1 , and it remains essential throughout the first years of life. A proper balance of nutrients in this formative period is critical for normal brain development. Similarly, there is growing evidence that DHA, an essential fatty acid, is a key component of the intensive production of synapses that makes the first years of life a critical period of learning and development. Many other nutrients—choline, folic acid, and zinc, to name just a few—have been linked specifically to early brain functioning. The role of nutrition in brain development is complex. Early shortages can reduce cell production; later shortages can affect cell size and complexity. Nutrient deficits also affect the complex chemical processes of the brain and can lead to less efficient communication between brain cells.
Отключение ТРАНСТЕКСТА было логичным шагом в случае возникновения чрезвычайной ситуации, а ведь тот был уверен, что в машину проник вирус. К несчастью, это был самый надежный способ собрать в шифровалке всех сотрудников Отдела обеспечения системной безопасности. После таких экстренных действий на главном коммутаторе раздавался сигнал общей тревоги.
