Omega-3 and eye disorders age-related

Eye health and quality of life are related, it is therefore important the prevention and control of eye disorders, above all keeping in mind that they are common and can go unnoticed for a long time (because some have no symptoms at first). We should visit an ophthalmologist at least in the same way we should do with the dentist, for example, since early treatment is key to prevent some […]


Findings that support an increased dietary consumption of omega-3 in older people

Healthy ageing is generally defined as survival without chronic diseases or cognitive and physical dysfunction after age 65, but the definition of the World Health Organization includes other aspects; it defines healthy ageing as the process of developing and maintaining the functional ability that enables wellbeing in older age. Functional ability is having the capabilities that enable all people to be and do what they have reason to value: meet […]


EPA and DHA potential effects on Alzheimer's risk

Alzheimer disease is the most common neurodegenerative disorder (it constitutes 60-80% of all dementias) worldwide, with 1 in 5 people aged >80 y having Alzheimer. Globally, 35.6 million people are living with dementia and this number is expected to reach 115.4 million by 2050. With the aging and the life expectancy of the world population increasing, developing interventions to prevent and treat Alzheimer disease/dementia has become an public health priority. […]


A good news for aging people

Dementia is not a specific disorder, but a general term for a decline in mental ability severe enough to interfere with daily life (memory loss is an example). Alzheimer’s is the most common type of dementia (it accounts for 60 to 80 % of cases); vascular dementia, which occurs after a stroke (a cerebral infarction), is the second most common dementia type. It is estimated that 46.8 million people worldwide […]


Omega-3 fatty acids supplementation could improve visual acuity development

In a recent global analysis of 38 studies that had been conducted on the effects of omega-3 fatty acids consumption on child cognitive development (which altogether involved 5,541 participants), the outcomes showed that, in comparison with placebo (an innocuous substance), omega-3 fatty acids supplementation improved visual acuity development. Visual acuity is a measure of the finest detail that can be recognized by the visual system, the clarity or sharpness of […]


DHA contributes to the brain and visual development of infants

DHA is a structural constituent of cell membranes; although it is present in other tissues (for example, it is also found in high concentrations in the visual system), its concentrations in the central nervous system are unique in terms of its high levels. DHA accumulation in the fetal brain takes place mainly during the last trimester of pregnancy and continues at very high rates up to the end of the […]
