Children who drank cow’s milk “basic” for a year grow more than those who were breastfed because of the fact that cow milk composed of high rich protein.
A high consumption of cow’s milk before the age of one year is associated in several studies to a size and weight gain faster than breastfeeding. But rapid weight gain in infancy may increase the risk of obesity later in childhood, and risk of cardiovascular disease in adulthood.
A new study of British children in 1112 to better understand the reasons for the rapid weight gain in infancy. The children were classified according to that at the age of 8 months they were breastfed, they received an infant formula (based on cow milk adapted) or conventional supermarket like they drank cow’s milk. Weight and height were measured 14 times until the age of 10 years.
Results: Children who drank milk from cows classic (at least 600 mL per day) at the age of eight months were significantly heavier than breastfed children for the duration of the study, the greatest difference occurring in age of 18 months. Their body mass index was also significantly higher. They were larger, between 25 and 43 months. Between 8 and 37 months, children fed milk formulas (which provide less protein than milk basic cow) were also heavier and taller than breastfed infants, since these formulas represented more than 600 mL per day the age of eight months.
The study published in the American Journal of Clinical Nutrition suggests that small children who drink cow’s milk have trouble regulating their energy consumption. At the age of eight months, they swallow nearly 180 more calories and 72% more protein that breastfed children. Children taking an infant formula also receive more calories than breastfed children and almost 20% more protein.
About 20% of cow’s milk calories come from protein, 2 to 3 times more than in breast milk. These non-standard amount of protein has an impact on the level of growth hormone and growth factors, especially that of IGF-1, which is substantially increased at any age when consuming milk products.
This study supports the recommendations of the American Academy of Pediatrics and those of the Ministry of Health of the United Kingdom: no “basic” cow milk before one year.
