Omega-3 and obesity

In several studies it has been found that increasing the intake of omega-3 by 0,3–3,0 g/day can improve the composition of our body, reducing body weight and body fat in overweight and obese people. One of them examined the fatty acid composition of abdominal adipose tissue samples of 84 obese patients (the adipose tissue is a connective tissue consisting mainly of fat cells). The researchers found that abdominal obesity (waist-hip […]

 
 
 
 

Brain aging and DHA

Lower levels (in comparison with higher levels) of DHA in red blood cells of people free of dementia are associated with smaller brain volume and a pattern of cognitive impairment similar to the persons who have dementia. This is the conclusion reached by a study with 1575 dementia-free participants, from 58 to 76 years of age, in which they had to perform cognitive tests (to measure brain aging) and to […]

 
 
 
 

Omega-3, osteoporosis and menopause

Famous actresses as Sally Field or Carmen Maura confess to suffer from osteoporosis, the most common type of bone disease, which weakens the bones to the point they become fragile and break easily. Bone is a living tissue that is constantly being replaced by new bone, and osteoporosis occurs when the body doesn’t form enough new bone, when too much existing bone is reabsorbed by the body or both things.

My baby is so cute, but was born so small...

Do you knew that impaired fetal growth is associated with arterial wall thickening, a risk factor for cardiovascular diseases in adulthood? Each -1 kg lower birth weight translates to a 10% to 20% increase in risk of coronary artery disease many decades later. It is only a risk factor, but one we can act on. As a result of a big study, the Childhood Asthma Prevention Study (that involved children […]

 
 
 
 

Here comes the sun

Exposure to ultraviolet (UV) radiation, a form of energy emitted by the sun that we can’t see or feel, is the principal environmental cause of skin cancer, and causes mutations in the p53 gene (fundamental in the mechanisms protecting skin cells from malignant transformations). In the majority of the most common skin cancers, these mutations (a marker of early UV-induced carcinogenesis) can be observed and quantified in the blood serum, the […]

 
 
 
 

DHA and macular degeneration (II)

The Omega-3 fatty acid DHA is found in high concentration in the retina and is required for its proper function (it has been reported that DHA intake is inversely related to the risk of age-related macular degeneration – AMD). On the other hand, lutein and zeaxanthin (two carotenoids which act helping protect and maintain healthy cells) are also deposited in high quantities in the macula. The quantity of lutein and […]
