Back to the fashion of cod liver oil - March 3, 2004
After decades of disuse, the oil terror-of-children of past generations back to be talked about for its new properties to fight many ailments including osteoarthritis and asthma
The grandmothers were right. The cod liver oil is good for almost anything. To confirm this is a study conducted by a team of researchers according to which Welsh is also effective against osteoarthritis. In 31 patients suffering from osteoarthritis, and waiting to be operated on the knee, were given special tablets for nearly three months. For one half of the sample consisted of two capsules daily 1,000 mg of cod liver oil. To other sufferers vice versa has been given a simple placebo. Experimentation has shown that 86% of patients treated with oil at the end of treatment, was almost completely devoid of the enzyme responsible for the damage to the cartilage. Conversely, only 26% of those who took placebo were detected improvements.
The discovery of professors John Harwood and Bruce Caterson (Cardiff University) and prof. Colin Dent (orthopedic University of Wales) could therefore significantly reduce the number of hip and knee operations. In Britain, only in the last year, were two million patients suffering from osteoarthritis.
'The data suggest that the cod liver oil has a dual effect: on the one hand slows down the degeneration of cartilage in osteoarthritis, on the other hand reduces the inflammatory processes that cause pain,' said Professor Caterson.
The healthy principles of this type of oil are known for years. Thanks to the massive presence of vitamin D and A (an amount three times greater than that which there is in beef liver), cod liver oil is used to treat ear infections and allergies, enhances the functionality of the brain , and is a valid cure to stress and other behavioral disorders.
But this is not all. The hated cod liver oil, liberally administered to past generations of children, there has probably helped to combat the symptoms of asthma, of which today suffer million people, two million of them in Australia.
A study by the Institute for the Prevention of childhood asthma, concluded that Omega-3 fatty acids, which are found in canola, the tuna and cod liver oil, can significantly reduce symptoms such as coughing and wheezing, in children of parents who suffer from asthma.
The results, presented at the Australian Conference for asthma underway in Melbourne are based on a program that has followed 6,161 children from birth. The study indicates that the reduction of dust mites in bedding, and the elimination of the plush toys produces positive results in terms of allergies, but the Omega-3 supplements are even more effective against cough and wheezing. It 's too soon - says the researcher prof. Craig Mellis Bond University - to determine whether any of the children has actually contracted asthma, but the effect of Omega-3 on children of three years was "statistically impressive."
Cod liver oil for depression - August 20, 2007
In time of war was given to the children, who hated the taste. Now it turns out that its properties can also be useful to combat depression and 'a remedy that refer to other eras, when it was given to children to help them stay healthy, thanks to the high vitamin content. But now it appears that the abhorred cod liver oil also has other potential ': in particular, a study says, can' be useful to avoid depression.
Indeed, the researchers say, a tablespoon a day reduces by 30% the chance of being a victim of the disease.
In their study, which is published in the Journal of Affective Disorders, researchers at Haukeland University of Bergen in Norway, examined the health status and dietary habits of 22,000 people over 40 years. They then observed that those who do not consume cod liver oil have a significantly higher percentage of stress, anxiety and depression. In contrast, 9% of examined people, who ingest a tablespoon per day, show a lower percentage of 30% of these states of psychological discomfort. According to the researchers, this is further evidence of the beneficial effects of fatty acids called omega-3, which are a critical component of the oil.
Omega 3, according to several studies are useful to protect against stroke and heart attack, and even by the tumor. The cod liver oil is obtained by steam cooking the liver of these fish, and then press it and extract the precious liquid, which is rich in vitamin A and D. In Britain, during the Second World War, was distributed free of charge to children 5 years old, pregnant women and those who were breastfeeding.
