An extract derived from Pacific oysters has demonstrated the ability to reduce inflammation in intestinal cells, according to research from the University of Ferrara in Italy. This finding suggests a potential pathway for oysters to mitigate cancer risk, as chronic inflammation is a known contributing factor to various diseases, including cancer.
The study, presented at the Society for Experimental Biology conference in Florence, Italy, focused on the anti-inflammatory effects of an extract made from dried Pacific oyster meat. Researchers tested this extract on intestinal cells and observed a significant reduction in inflammation.
Chronic inflammation is implicated in a range of health issues, such as type 2 diabetes, cardiovascular disease, and inflammatory bowel disease. It can be exacerbated by a compromised intestinal barrier, often referred to as 'leaky gut,' which allows toxins and bacteria to enter the bloodstream. Some scientific discussions have pointed to gut inflammation as a potential factor in the increasing rates of bowel cancer among individuals under 50.
Giulia Trinchera, a PhD student at the University of Ferrara who worked on the study, stated that this is the first known instance of oyster tissue exhibiting anti-inflammatory effects on intestinal cells. However, she emphasized the need for further research, including additional experiments and human trials, to confirm these effects, determine optimal dosages, and identify the specific bioactive compounds responsible for the observed anti-inflammatory activity.
Previous research has highlighted the nutritional benefits of seafood, including oysters, noting their rich content of lean protein, omega-3 fatty acids, vitamin B12, iron, and selenium, all of which are associated with a lower risk of heart disease. Oysters have also been noted for their potential to boost libido, attributed to their high zinc content, which supports testosterone production and reproductive health.
In the United Kingdom, approximately 30 million oysters are consumed annually. The majority of these are non-native Pacific oysters, cultivated in various regions. Native oysters constitute a much smaller portion of the market.
