DHA protects brain cells against the effects of alcohol

It is known that alcohol abuse causes brain damage (and other health problems), leads to inflammation and cell death, causes mild-to-moderate cognitive impairment and, in case of long-term abuse, increases the risk of dementia. Brain-imaging techniques reveal structural, functional and biochemical changes in the brain of persons who abuse alcoholic beverages. In a recently published study, researchers exposed cultures of adult rat brain cells to high amounts of alcohol and […]


Women, depression and omega-3

In order to assess the relationship between omega-3 / depressive symptoms, the National Institute on Aging (USA) conducted a study from 2004 to 2009 in 1746 adults (30-65 y). Depression was evaluated using the Center for Epidemiologic Studies Depression scale, a short self-report test designed to measure depressive symptomatology in the general population. Total scores can range from 0 to 60, but a score ≥16 suggests elevated depressive symptoms. Fatty […]


Infertility problems? Intake of omega-3 fatty acids improves semen quality

It is considered that a man has fertility problems when his partner has been unable to conceive naturally after at least one year of trying (without using birth control methods and having confirmed the woman’s fertility), due to physical or hormonal problems, lifestyle or environmental factors. In the past 50 years, sperm density has fallen by 40%. Spermatozoa from asthenozoospermic (reduced motility or vitality of sperm) and oligozoospermic (reduced number […]

Omega-3 DHA and the quality of your children’s sleep

Preliminary data from a study of the University of Oxford, that involved 395 healthy children aged 7-9 years, indicate significant associations between blood omega-3 status and sleep problems in children. Both sleep problems and dietary deficiencies of omega-3 fatty acids such as DHA are associated with poor general health and with behavioural and cognitive problems (underperforming in reading, for example). In this research, supplementation with 600 mg/d of DHA for […]


Do you still have doubts about benefits of oral supplementation?

If so, pay attention to a study presented this month at the European Society for Clinical Nutrition and Metabolism annual congress: an eleven-year retrospective study (2000 to 2010) assessed the effect of inpatient oral nutritional supplement use on length of stay and 30-day readmission probability (in the case that the patient was at risk of readmission) on 1.2 million adult inpatient episodes. The study compared hospital stays where oral nutritional […]


How to improve brain function and structure in elderly people?

High intake of omega-3 fatty acids may be beneficial for the aging brain, improving its structure and the cognitive function. Sixty-five healthy subjects (50-75 years) received for 26 weeks either omega-3 fish oil (2.2 g/d) or placebo. After this period, comparisons between the two groups were made in cognitive performance, neuroimaging and blood tests. The researchers found a significant improvement in executive functions after omega-3, compared with placebo. Executive functions […]
