Omega-3 and impact of air pollution

Air quality in most cities worldwide fails to meet World Health Organization guidelines for safe levels. About half of the people living in cities reporting on air quality is exposed to air pollution that is at least 2.5 times higher than the levels recommended by this organization. More than likely, all of us are exposed to air pollution in some degree. Air pollution is a mixture of gases, liquid droplets […]

In a study designed to evaluate the effect of fish oil supplementation rich in DHA, with and without regular exercise, on heart rate variability (the variation in the time interval between heartbeats) in overweight adults with risk factors for coronary disease, fish oil supplementation improved heart rate variability (compared with placebo). And it also reduced heart rate at rest and during submaximal exercise (physical activity whose intensity increases at regular […]


Winning the battle against free radicals

They are molecules that are formed when we do exercise, when our body produce energy and when we are exposed to environmental factors as cigarette smoke, environmental pollution or UV radiation. The feared free radicals are such because they can cause oxidative stress, which is the result of an imbalance between pro-oxidants and antioxidants molecules, and this […]


Where is the border line between permissive diet and poor nutrition?

At this stage, we already know that long-chain omega-3 fatty acids from fish oil play an important role in cognitive performance throughout all life phases, from childhood (brain development) to old-age (to defer cognitive decline and prevent age-related eye-diseases). With respect to childhood and according to some studies, it would seem as if children with low literacy ability and who are malnourished with low omega-3 intakes may benefit most from […]
