Healthy eating habits

We must eat different foods in order to obtain the calories and nutrients we need. But how to choose the right foods to have a healthy diet? Here are some guidelines: Eat mainly vegetables, legumes and fruit. A diet rich in vegetables (potatoes don’t count) and fruits can decrease the probability of having a cardiovascular disease, cataract and macular degeneration, and possibly protects against some types of cancers. Eat whole […]


DHA and prevention of cognitive problems

During gestation, DHA accumulates in brain tissue (especially during the third trimester). After birth and during childhood, DHA levels continue to increase in the areas associated with mental processes that enable us to plan, focus attention, remember instructions, and perform multiple tasks successfully (cortical areas). And during adolescence the increasing in DHA levels goes on, while the human brain matures. Over the past 30 years, evidence from animal and clinical […]


What is memory and how it works?

Memory refers to the processes used to acquire, store, retain, and later retrieve information. How it works? Information is encoded and stored for later use (retrieval), when we need to use it. Long-term memory can be declarative (the memory of events, that can be consciously recalled) or procedural (the unconscious memory of how to do things). In turn, declarative memory can be subdivided into episodic memory and semantic memory. Episodic […]


Omega-3 for aggressive behaviour

Today, we share a curious new: Prisoners with lower omega-3 index (EPA + DHA level in red blood cells) are more aggressive and have higher scores in attention deficit disorder scales. Lately, it has been observed that omega-3 supplementation contributes to a decrease in aggressive behaviour in prison populations. In order to evaluate this observation, a group of Australian researchers have conducted a study with 136 adult male prisoners: their […]


Omega-3 supplementation in the treatment of children with ADHD

Attention Deficit/ Hyperactivity Disorder (ADHD) is a common child disorder, often treated with stimulant medication (methylphenidate). But lately, the interest in non-pharmacological treatments is increasing, due mainly by the secondary effects of medication. These approaches include dietary supplementation with omega-3 fatty acids. To evaluate the effects of dietary omega-3 fatty acid supplementation on ADHD symptoms in boys aged 8-14 years with and without ADHD, 44 boys with ADHD and 39 […]


Omega-3 may improve antidepressant response

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants. They improve mood and behaviour in people with depression and generally have fewer side effects than most other antidepressants. But up to 50% patients do not respond to treatment with SSRIs. Recently, a group of researchers have performed a study in which increasing fatty fish (rich in EPA and DHA) intake appears to increase the percentage of response in […]
