Sport and omega-3

As we have said on previous posts, human beings evolved consuming a diet that contained amounts of omega-6 and omega-3 in a ratio of about 1:1 to 2:1, but dietary changes over the past decades in the intake of these polyunsaturated fatty acids have increased this proportion. Nowadays, in Western diets the ratio is between 15:1 and 16.7:1 (optimal dietary intakes should be around 1-4:1). Needless to say, Western diets [...]

It clouds the lens, the transparent part of the eye that collects and focuses light on the retina to form clear images; it is located posterior to the cornea and iris, has no blood vessels (receives nutrients from the aqueous humor) and consists mainly of proteins (98%). In the lens, new cells are formed throughout life, but older cells are usually [...]

Anything that increases the chance of developing cancer is called a cancer risk factor; anything that decreases the chance of developing cancer is called a cancer protective factor. Breast density is a cancer [...]

 
 
 
 

EPA, DHA and brain volume

Our brain is the largest among the mammals. Yes, whales and elephants have larger brains in absolute terms, but the human brain is larger than any other in relation to body size. The human brain is triple the size of ancestors that lived 3 million years ago and it is three times as large as the brain of a chimpanzee, our closest living relative. Much of the brain expansion is [...]

 
 
 
 

How can omega-3 help children with refractory epilepsy?

About one-third of people with epilepsy will develop refractory epilepsy: they will be treatment-resistant patients (people for which medicines don’t control the seizures). Because of the impact of seizures on physical, social and psychological functions, these people may have trouble at work or school and, may even, have injuries as a result of their seizures. A special diet, called a ketogenic diet, may help control the seizures. This diet, medically [...]
