Omega-3 and the consequences of air pollution

In the air that makes life possible for plants, animals and humans there are always solid and liquid particles of organic and inorganic substances suspended; but when pollutant particles dirty the air, the survival of the living beings is in jeopardy. As we have already discussed in another post, exposure to air pollution is linked to health risks. Pollutants in the air come from many different sources, but they are […]


DHA in persons with mild cognitive impairment

The hippocampus is a small region of the brain that forms an important part of the limbic system, the area that regulates emotions, and is involved in the storage of long-term memory (all past knowledge and experiences), spatial orientation, and spatial memory. Damage to the hippocampus can lead to loss of memory and difficulty in establishing new memories, and there is a correlation between hippocampal atrophy (the reduction of its […]


Omega-3 in obesity and related disorders

Obesity and the disorders associated with it (high blood pressure, high blood sugar, abnormal cholesterol levels, etc.) are a growing health problem in the developed world. They are related with a higher risk of developing metabolic syndrome, which in turn, can increase the risk of heart disease, stroke, and diabetes. Furthermore, obesity is associated with non-medical issues as diminished mobility, and social stigmatization. Adipose tissue (fat) has a very important […]


Prenatal DHA may improve attention at 5 years of age

Attention allows: alert to the existence of stimuli, select information and maintaining attention in the face of distracting stimuli. Attention is selective. The factors that promote selection can be described as either exogenous (external) or endogenous (internal): exogenous factors are the characteristics of the stimuli (such as its frequency and duration, for auditory stimuli, and intensity and brightness for visual stimuli); endogenous factors are those cognitive processes that allow the […]


Omega-3 and testicular volume

In 30-50% of couples with fertility problems the man has poor semen quality. The onset in sperm production begins at puberty, and once it has started, it continues almost constantly until death (although testicular tissue mass decreases with age and this involves changes in sperm production). Sperm quality is measured by the amount, the movement, and the size and shape of sperm. With respect to the amount, the ejaculates of […]


DHA, exercise and mitochondrial metabolism

Mitochondria are small structures floating inside the cell and act like a digestive system: they create energy rich molecules for the cell by combining oxygen (from the air we breathe) with the sugars and fats that come from the food we eat. They are the main source of energy for the body. Some cells have several thousand mitochondria (germ cells, for example) while others have none (red blood cells and […]
