Vision plays a fundamental role in how an infant perceives the world and learns. A balance of proper nutrients is essential for optimal eye development.
At birth, newborns see only vague shapes around them. Infancy and early childhood are periods of rapid eye development, with sharpness of vision developing during the first four years of life. Healthy vision plays a fundamental role in how infants and young children learn and perceive the world around them. Lutein, zeaxanthin, DHA (docosahexaenoic acid), vitamin A and vitamin E are important nutrients for healthy development of an infant’s vision. During early life, infants obtain these essentials nutrients through breastmilk.
Science shows that lutein and zeaxanthin are antioxidants concentrated in the macula, located in the back of the eye, and in the brain. Because the human body cannot make lutein or zeaxanthin, we must consume these nutrients either from foods, such as leafy green vegetables, eggs and corn, or from supplements. For breast fed babies, colostrum and breastmilk are rich sources of lutein and zeaxanthin, with the concentrations in breastmilk proportional to a mother’s intake of these nutrients.1
Lutein and zeaxanthin serve as filters of blue light, a type of light which has the potential to damage eyes. For the infant brain, research shows a preferential deposit of lutein compared to other antioxidants.2 FloraGLO Lutein supplementation has been shown to increase the antioxidant capacity in healthy, full-term newborns when administered very early in life.3
DHA and ARA are the primary omega-3 and omega-6 fatty acids found breast milk. They are both present in all human cells. However, DHA is the most abundant omega-3 fatty acid in the brain and the retina of the eye. ARA is the most abundant omega-6 fatty acid in the brain.
A mother’s intake of DHA during pregnancy influences the DHA status of the mother, her developing baby and her growing infant infant after birth. Breast milk naturally contains both DHA and ARA. Brain,4-10 vision6,11,12 and immune function13-15 benefits were reported in the children of mothers who had a higher DHA intake and/or status during pregnancy. Maternal and infant DHA status16 during lactation is also important.
Supplementation of breast feeding mothers during lactation with algal DHA increased the DHA content of her breast milk and the status of her infant. This resulted in cognitive benefits at 30 months of age17,18 and 5 years of age19. This suggests a programing effect as the benefits continued well past the point of supplementation
Vitamin A as retinal is a structural component of the visual pigments of cells in the retina that detect light, supporting night vision. Vitamin A and vitamin E are both key to normal eye development. A severe deficiency of vitamin A can lead to night blindness. Vitamin E protects the eyes against damage by fighting free radicals as an antioxidant.
