Babies who are conceived in late winter or early spring are at greater risk of developing food allergies.
Scientists say that between April and May, when a baby in the womb reaches 11 weeks of development, he is twice as likely to suffer from allergies to such common ones products like milk and eggs.
It is possible that the high level of pollen on the trees is to blame for everything, and the child is just beginning to develop antibodies.
The researchers also say that the mother's low vitamin D level after winter also plays a role, which reduces the child's immune defense.
The most vulnerable children in this regard are those born in October and November.
The researchers studied nearly 6,000 children born between April 2001 and March 2006 who were living in southeastern Finland. About 11 percent of children who had 11 weeks of fetal development between April and May were more likely to have food allergies. The same children who had 11 weeks of fetal development between December and January had only a 6 percent risk of developing allergies.
The study found that birch and alder pollen levels were highest in April and May.
Experts have previously discovered that tree pollen can trigger food allergies, and a recent study confirms this.
It is known that 6 to 8 percent of children under three years of age suffer from food allergies, and some have serious reactions.
Over the past 30 years, the number of children suffering from asthma and allergies has increased significantly, due to many factors, such as excessive cleanliness, poor diet and early use antibiotics.
Dr Kaisa Pyrhonen, who conducted the study with a team of scientists at Oulu University Hospital in Finland, says that they We found a higher incidence of food allergies in children born in October and November compared to children born during other periods.
Overall, tests showed that about 18 percent of children were allergic by age four.
