In the United States, about 10% of children under 18 are affected by ADHD, which is more common in boys than in girls. ADHD symptoms usually show up in childhood and persist until puberty or even after adulthood. At present, there is no cure method, including drug, psychotherapy, training to alleviate symptoms.

According to the Daily Mail of March 28, a new study shows that the diet of pregnant mothers may increase the risk of attention deficit hyperactivity disorder (ADHD) in their babies. In the past, it was often recommended that pregnant women eat nuts, soybeans and other foods rich in omega-3 and omega-6 fatty acids, but this recent study shows that these foods are too late, which increases the risk of distraction and hyperactivity in babies by at least 13%.

Previous studies have shown that mothers who eat nutritious foods during pregnancy preparation and pregnancy can affect their children's metabolic health. However, the Barcelona Institute for Global Health (ISGlobal) said the study was the first to show that the diet of expectant mothers causes neurodevelopmental disorders in children.

_-3 and_-6 fatty acids are two kinds of polyunsaturated acids. Instead of producing the enzymes they need, the human body gets them from nuts and eggs such as salmon, walnuts, cashew nuts and soybeans. These fatty acids are very important for the health of the central nervous system during pregnancy and after birth. _-6 unsaturated fatty acids can stimulate inflammation, while_-3 unsaturated fatty acids have anti-inflammatory effect, experts believe that the balance between the two is very important.

In the past studies, it was found that the contents of_-3 and_-6 unsaturated fatty acids in children with attention deficit hyperactivity disorder (ADHD) were high, and the specific reasons were not yet clear.

In this new study, the team studied 600 children who participated in the INMA project. The project is run by several Spanish teams to study environmental pollutants during pregnancy and the first year of life, and to analyze their impact on child development. Umbilical cord plasma samples were collected and questionnaires were distributed to the subjects.

In umbilical cord blood samples from 7-year-old children, ADHD symptoms were more frequent in children with higher proportion of omega-3 and omega-6 unsaturated fatty acids. The risk of ADHD symptoms increases by 13% for each unit of increase in the proportion. In 4-year-old children or doctors, the proportion of two fatty acids was not related to ADHD symptoms. In addition, two questionnaires were used to assess children's ADHD symptoms such as distraction, hyperactivity and impulsiveness. One was filled out by a teacher of a 4-year-old child and the other by a parent of a 7-year-old child.

Dr Nica Lpez-Vicente, lead author of the study and researcher at ISGlobal, said: "Our findings are consistent with previous studies and establish a relationship between the proportion of omega-3 and omega-6 unsaturated fatty acids in mothers and early neurodevelopment." Although the relationship is not clinically significant, our findings are significant for the entire population. Meaning. "

Some studies have shown that maternal diet during pregnancy has a long-term impact on newborns. A study released last week by the University of Washington Medical School showed that high levels of fat and sugar in the diet of experimental mothers during pregnancy increased the risk of heart problems in offspring. A 2008 Wellcome Foundation study also showed that unhealthy diet during pregnancy increases the risk of obesity and high cholesterol in children.

Jordi Jlvez, co-author of the study and assistant researcher at ISGlobal, said, "Early nutritional supply is critical to the structure and function of organs. In turn, organ development has an impact on health at every stage in the future." Brain development takes a long time and is prone to coding errors. So this change may lead to neurodevelopmental disorders.

In an interview with the daily mail, Andrew Chernus Andrea Chernus, New York's Chernus Nutrition, advised pregnant women to get Omega -3 unsaturated fatty acids such as salmon and sardines, and she said, "shorter lived fish contain less mercury." She also suggested limiting the intake of omega-6 unsaturated fatty acids, which are higher in edible oils such as soybean oil, corn oil and processed foods.

Tammy Lakatos Shames of Nutrition Twins, a nutrition consultancy, also recommends reducing the intake of omega-6 unsaturated fatty acids appropriately and increasing the intake of omega-3 unsaturated fatty acids. "Pregnant women take some good fish oil supplements because they are rich in DHA, which is very important for the health and development of their babies.
