Down syndrome implies the presence of an additional chromosome 21 or a part of that chromosome. The cause of Down syndrome is independent of human race, economic conditions and cultural aspects. The excess of chromosomes in each cell of people with Down syndrome causes certain differences compared to people who have 46 chromosomes. Some people have only a few accompanying health, developmental or intellectual difficulties, while others have serious health conditions that require medical intervention after birth. The promotion of a healthy lifestyle for a child with Down syndrome, as well as for the child's family, is very important because it provides the basis for the adoption of correct behavior patterns that will contribute to the child's health and quality of life in adulthood. The results of a survey of 104 parents of children with Down syndrome showed that almost half of the children have some form of heart defect. From carbohydrates, children mostly consume white bread, rice, pasta and potatoes. Milk is consumed daily by 21,2 % of children, cheese by 7,7 %, and fermented milk products by 24,0 %. Children mostly consume fruits and vegetables once a day. Children usually consume meat up to 5 times a week, and fish and eggs 1-2 times a week. More than half of the children consume olive oil, and 78,8 % consume water daily. 81,7 % do not consume fast food or rarely consume it, 34,6 % sweets, and 33,7 % snacks.
