In a study designed to estimate intake of PUFAs, identify sources of PUFA and estimate the proportion of US children aged 12-60 months eating fish by age, race and ethnicity it was found that 47% of children do not consume fish. The results from the study indicated DHA intake was low across all groups, and only 53.7% of children reported eating fish in the last 30 days. The study also found a greater percentage of non-Hispanic black children ate fish overall, and Mexican American children were more likely to have eaten shellfish than non-Hispanic white children. Total n-3 intake did not significantly change with age, but total n-6 intake increased significantly. Compared to other countries, US children consumed higher intake of total n-6 and demonstrated lower DHA and EPA intakes.
Dietary Patterns, n-3 Fatty Acids Intake from Seafood and High Levels of Anxiety Symptoms during Pregnancy: Findings from the Avon Longitudinal Study of Parents and ChildrenAuthors: Juliana dos Santos Vaz, et al. / Journal: PLOS One, July 2013
Excessive anxiety during pregnancy is associated with low birth weight, shorter length of gestation, and negative effects on infant brain development, including stress regulation. Among over 9,500 pregnant women in the UK, those with no intake of omega-3s from seafood had a 53% greater likelihood of high levels of anxiety when compared to pregnant women who got at least 1.5 grams omega-3s from seafood per week.
Intake of fish and marine n-3 polyunsaturated fatty acids and risk of breast cancer: meta-analysis of data from 21 independent prospective cohort studiesAuthors: Ju-Sheng Zheng, et al. / Journal: British Medical Journal, June 2013
Higher consumption of dietary marine n-3 PUFA is associated with a lower risk of breast cancer. The associations of fish and alpha linolenic acid intake with risk warrant further investigation of prospective cohort studies. These findings could have public health implications with regard to prevention of breast cancer through dietary and lifestyle interventions.
