Grape Seed Extract May Stop Bacteria Involved in Bad Breath and Gum Disease

A new study suggests that grape seed extract may inhibit the bacteria known to cause bad breath and gum disease.

Periodontitis is a gum disease that destroys the soft tissue and bone supporting the teeth. Thirty to 50 percent of the US population suffers from the condition, which is thought to be the second most common disease worldwide.

In an in vitro study, researchers investigated whether grape seed extract could inhibit Porphyromonas gingivalis and Fusobacterium nucleatum, bacteria responsible for both periodontitis and bad breath. The researchers tested the effects of grape seed extract (97 percent polyphenols) on these two anaerobic bacteria.

The results indicated that grape seed extract exhibited antibacterial activity against the two strains. Moreover, the grape seed extract could penetrate the biofilm that surrounded the bacteria. Biofilms serve to protect bacteria against antimicrobial agents and dental plaque’s biofilm is particularly complex.

Grape seed extract also had an antioxidant activity higher than vitamins C and E, according to measures taken with the Trolox equivalent antioxidant capacity (TEAC) test. This was important to the findings of the study because gum disease originates due to the bacteria’s presence and its biofilm protection, but the disease progresses because of an excess release of reactive oxygen species that trigger the inflammatory process. Grape seed extract’s antioxidant abilities may quench the free radicals implicated in the progression of gum disease.

The researchers concluded, “These findings indicated that GSE could be used in oral hygiene for the prevention of periodontitis.”

Omega-3s Linked to Prostate Health

Men who increase their intake of omega-3-rich fish have a greater chance of surviving prostate cancer, according to a new study.

Researchers studied 20,167 men who were participating in the Physician’s Health Study. The subjects were free of cancer in 1983, when the study began. During follow-up, 2,161 men were diagnosed with prostate cancer and 230 died of the disease.

Although intake of omega-3-rich fish was unrelated to prostate cancer incidence, it was linked to survival from the disease. Among the men diagnosed with prostate cancer, those consuming fish five or more times per week had a 48 percent lower risk of prostate cancer death than did men consuming fish less than once weekly.

In this study the scientists found no link between fish consumption and a reduced incidence of prostate cancer, but the same researchers conducted an earlier study that found higher intake of the omega-3 fatty acids DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) may reduce the risk of developing prostate cancer by 41 percent.

The Deadly Truth About Diabetes


The Thin Man’s Diabetes

America‘s fastest-growing disease has a sugar-coated secret: You don’t need to be overweight for it to kill you

By: Jeff O’Connell

One of my most enduring childhood images is from a newspaper clipping. The grainy photograph freezes a lanky teen named Tom O’Connell launching a hook shot from his right thigh. Tucker, as he was known, led a team from tiny Merchantville High School in scoring and rebounding during an improbable run to the South Jersey Championship. New Jersey had its own version of Hoosiers in 1952, and for that one season, my father was his team’s Jimmy Chitwood.

Supply of hospital pharmacies operating externally due to cost savings will continue to grow all over the next years. Even today, 90% of all pharmacies pribolnichnyh organized in cooperation provisioning This shows that the Canadian pharmacy online has become not take seriously the business partner compared with the pharmaceutical industry. However, the development of recent years shows that the industry sees its price registration stronger with the number of sales, thus strengthening the competitiveness of supplying hospital pharmacies in the long term due to more efficient logistics and a lot of sales.
