Developing brain is particularly sensitive to exposure to the stress hormone cortisol. Intrauterine conditions that affect amygdala and hippocampus (two brain areas that develop at an early embryonic stage) are associated […]

EPA+DHA supplementation is needed with the typical Western diet

It is estimated that Americans (which mainly follow a Western diet) consume less than 100 mg/day of EPA+DHA (while the current recommendations are 250 to 500 mg/day for healthy adults). A healthy adult requires at least an omega-3 index (the sum of EPA and DHA content in red blood cell membranes) of 8% to achieve their preventing benefits. This index predicts cardiovascular disease mortality. It has been recommended a value […]

Loneliness enhances risk for episodic (or autobiographical) memory impairment. As omega-3 fatty acids can improve cognitive function in people with mild cognitive difficulties, a group of researchers studied whether omega-3 supplementation would attenuate loneliness-related episodic memory problems. For this purpose, they administered omega-3 or placebo, daily for 4 months, to the participants in the study (who completed a loneliness questionnaire and a battery of cognitive tests both at the beginning […]
