Prenatal omega-3 intake and visual function in school age

In order to examine the long-term effect of omega-3 intake during gestation on visual development, a recent Canadian study has assessed the DHA and EPA concentrations in the umbilical cord of 171 Inuit children (mean age: 11.3 years old), whose mothers had previously participated in a Cord Blood Monitoring Program. The study assessed their visual acuity, using visual evoked potentials (that measure the electrical signals to the brain generated by […]

 
 
 
 

Omega-3 and overweight

A study has evaluated the combination of omega-3 with a very low-calorie diet and regular exercise: 27 obese women underwent a 3 week inpatient period of weight reduction in which some volunteers practised 60 min/day of light to moderate exercise. All of them were randomly assigned to consume either a very low-calorie diet (2200 kJ/day) supplemented with 2.8 g/day of omega-3 (ratio 2 EPA:1 DHA) or the very low-calorie diet […]

 
 
 
 

Omega-3 and memory

The results of the study we will discuss in this post show that daily intake of omega-3 from fish oil during a 5 week period significantly improves working memory in healthy subjects (the working memory refers to the simultaneous temporary storage and processing of the information necessary for complex cognitive tasks such as language comprehension, learning and reasoning). With the objective of evaluating the effects of dietary supplementation with omega-3 […]

Prenatal depression increases risk of preeclampsia, birth difficulties and postpartum depression (which, in turn, can have negative effects on the care given to the baby and the mother herself; and is linked to the development of depression in the adolescence of the child). Nutrient requirements are higher during […]
