In recent years there have been reports linking breast milk intake in infancy to lower blood pressure during childhood. The mechanisms underlying the relationship remain uncertain however there has been recent interest in the role of long chain polyunsaturated fatty acids (LCPUFAs). Several studies involving human adults have reported a lowering of blood pressure with n-3 fatty acid supplementation. Data relating to children are limited: however, two published randomised controlled studies report that LCPUFA supplementation in infancy may be associated with lower blood pressure in early childhood.
