Abstract
BackgroundA farming environment confers strong protection against allergy development. We have previously shown that farming mothers consume more full-fat dairy than control mothers, who instead consume more low-fat dairy, margarine, and oils; margarine and oil intake was associated with increased risk of allergy development in their children.ObjectivesThe aims of this study were to investigate the differences in diet between children in farming and control families at 1 year of age, to investigate the relation between the diets of the mothers and their children, and to relate the children's diet to allergy development.DesignThe diet of 1-year-old children from dairy farming families (n=28) and from control families in the same rural area (n=37) was assessed by 24-h dietary recalls, followed by 24-h food diaries. Allergy was diagnosed by pediatricians at 3 years of age using strict predefined criteria.ResultsFarm children had a higher intake of farm milk, whole cream, cholesterol, saturated fat, and fat in total and tended to eat more butter, while controls consumed more carbohydrates and poultry and tended to eat more margarine. Farm children also had higher intakes of homemade porridge/gruel, oily fish, and iodine. The intake of butter and whole milk in children and mothers correlated significantly in farm families but not in controls. A weak negative association was found between seafood intake and allergy development, while allergy was positively associated with the intake of pork as well as zinc in the control group; these intakes also correlated with each other.ConclusionsConsistent with mothers in farming families, the children consumed more full-fat dairy and saturated fat than did controls, but this could not be linked to the low risk of allergy in the farming group. Seafood intake might protect against allergy development, in accordance with earlier findings.

A farming environment confers strong protection against allergy development
Fish consumption did not differ notably between the farm and control mothers in our cohort [13], we found that the proportions of the long-chain omega-3 (n-3) polyunsaturated fatty acid (PUFA) eicosapentaenoic acid (EPA) in serum phospholipids in 4-month-old infants were associated with less allergy development; serum EPA correlated with the breast milk proportions of EPA, which in turn correlated with the maternal consumption of oily fish during lactation
Summary
We have previously shown that farming mothers consume more full-fat dairy than control mothers, who instead consume more low-fat dairy, margarine, and oils; margarine and oil intake was associated with increased risk of allergy development in their children. Objectives: The aims of this study were to investigate the differences in diet between children in farming and control families at 1 year of age, to investigate the relation between the diets of the mothers and their children, and to relate the children’s diet to allergy development. The intake of butter and whole milk in children and mothers correlated significantly in farm families but not in controls. Conclusions: Consistent with mothers in farming families, the children consumed more full-fat dairy and saturated fat than did controls, but this could not be linked to the low risk of allergy in the farming group. Seafood intake might protect against allergy development, in accordance with earlier findings
