Omega-3 and cognitive performance in adolescents

The brain develops until after age 20. During adolescence, the brain area most in development is the prefrontal cortex (an area especially enriched in DHA), which is very important in higher cognitive functions (inhibition and interference, working memory, and cognitive flexibility). These functions are used in reasoning and problem solving. So, they are important for academic success, although, of course, school performance depends also on other factors such as time […]

 
 
 
 

Delaying ovarian aging

In animal models, higher dietary omega-3 polyunsaturated fatty acids extend reproductive lifespan. In women with normal weight (but not in obese women) with normal ovarian reserve, dietary administration of 4 g/day of EPA + DHA decreases serum follicle-stimulating hormone (FSH) levels. In women, FSH helps control the production of eggs by the ovaries and the menstrual cycle (in men, FSH helps control the production of sperm). Ovarian reserve is the […]

 
 
 
 

Omega-3 and muscle health

Skeletal muscle is highly adaptable to diet and physical activity levels. So, the response of skeletal muscle to exercise can be modified by the nutritional status. The amount and type of fat in the diet play an important role in regulating body metabolic health: saturated fatty acids have been linked with the development of metabolic dysfunction while some monounsaturated fatty acids and polyunsaturated fatty acids have positive effects on metabolic […]

 
 
 
 

More about omega-3 and dyslexia

Dyslexia is a persistent difficulty in learning to read and write, despite having adequate general ability, motivation, and environment (which involves problems in short-term memory, sequencing of words or numbers, abnormalities of visual perception, and difficulties with spatial orientation). It is the most common learning disability, since it represents 80% to 90% of all learning disabilities. Evidence suggests that there is a connection between defects in polyunsaturated fatty acid metabolism […]

 
 
 
 

Omega-3, computers and vision

One in every 20 women over the age of 50 complain of one or more “dry eye” symptoms in the United States. When the ocular surface constituents (cornea, conjunctiva, eyelids, and tear film) and the lacrimal glands fail in preserving its integrity, “dry eyes” appears. This disorder usually affects people aged 50 years or more, particularly women, and has many risk factors (genetic, age, sex, nutrition, environmental conditions, lifestyle, working […]

 
 
 
 

EPA, DHA, and endometrial cancer type I

Endometrial cancer (endometrium is the inner lining of the womb) is the most common gynecologic cancer and the fourth most common for women worldwide. A PTEN gene mutation is present in approximately 40-80% of endometrial cancer cases, but its mutations have been also found in other types of cancer: prostate and colorectal cancers, some brain tumors and melanoma (skin cancer). This gene provides instructions to our body for making an […]
