Chronic low grade systemic inflammation is characteristic of obesity and may explain the link between obesity and chronic disease. There is evidence for infiltration of immune and inflammatory cells into adipose tissue, that leads to systemic inflammation (and subsequent organ damage). Compared to normal weight adolescents, obese adolescents have lower serum […]


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).

In the past 50 years, sperm density has fallen by 40%. Spermatozoa from asthenozoospermic (reduced motility or vitality of sperm) and oligozoospermic (reduced number […]
