THE RIGHT NUTRITION
“A healthy balance of proteins, fats, grains, vegetables, dairy and fruits is important to a child’s diet”, said Dr Lian Wee Bin, a paediatrician and neonatologist at the SpecialKids Child Health & Development Clinic. “Avoid saturated fats, added sugars and sodium-high foods,” she advised.
Several nutrients are essential for brain development, such as DHA, a fatty acid that is the structural constituent of membranes in the central nervous system; lutein, an antioxidant that protects the brain against harmful free radicals; and natural Vitamin E.
“Having sufficient DHA in the diet improves a growing child’s learning ability,” said Dr Lian. “Lutein protects DHA by reducing the oxidative damage related to free radicals. Its presence in neural tissues has recently been positively correlated with cognitive function. Natural Vitamin E helps to maintain cognition and brain plasticity.”
There are also gangliosides, which make up 10 per cent of the brain’s total lipid mass. As they are concentrated at the synapses where brain cells communicate with one another, gangliosides play a critical role in brain development.
Said Dr Lian: “Gangliosides are functionally involved in neurotransmission, supporting the formation of synapses and neural circuits, all of which form the structural basis of memory and learning. For infants, dietary gangliosides can impact positively on cognitive function.”
In addition to feeding children a healthy diet, parents may want to take note of recent advances in nutritional prebiotics.
Dr Lee Bee Wah, a consultant paediatrician and clinical paediatric immunologist at Mount Elizabeth Medical Centre, said that as the immune system resides primarily in the gut, nutrition plays an important role in developing children’s immunity.
For example, some formula milk brands contain 2'-FL, a milk oligosaccharide that has been associated with a reduction in the incidence of upper respiratory tract infections. The latest innovation is a blend of five types of milk oligosaccharides, which aims to feed good bacteria in the gut to strengthen the child’s immune system.
“Studies have shown that milk oligosaccharides may directly inhibit the invasion of viruses by blocking the adhesion of these organisms to the lining of the oropharynx – for respiratory viruses – and the gut, for gastroenteritis viruses,” explained Dr Lee. “Some clinical studies have also shown that infants who consume milk containing these oligosaccharides have fewer infections, compared to infants who consume milk without oligosaccharide supplementation.”
