Berry fruits help the brain stay healthy in several ways

Berry fruits help the brain stay healthy in several ways: Strong scientific evidence exists that eating blueberries, blackberries, strawberries and other berry fruits has beneficial effects on the brain and may help prevent age-related memory loss and other changes, scientists report.

Blueberry powder may control triple negative breast cancer

In continuation of my update on blue berry's usefulness....

Blueberry powder may control triple negative breast cancer: In several studies recently conducted at the Beckman Research Institute at the City of Hope, Duarte, CA researchers found that feeding blueberry powder to mice significantly reduced the growth and spread of triple negative breast cancer cells, a very aggressive form of cancer.

When Having the Blues is a Good Thing: Blueberries & Cancer Prevention

In continuation of my up date on the usefulness of blue berries.

Now researchers from the Department of Nutrition Sciences at the University of Alabama at Birmingham, lead by Laura Newton have come up with another interesting finding about blue berries, i.e., as little as a cup a day can help prevent cell damage linked to cancer.

As per the claim by the researchers, free radicals, atoms that contain an odd number of electrons and are highly reactive, can cause cellular damage, one of the factors in the development of cancer; many believe a diet filled with fruits and vegetables may help reduce the risk. 

Lead researcher says

"Studies suggest that antioxidants may help prevent the free-radical damage associated with cancer"

Researchers add that, Blueberries also are rich in vitamin C, which helps the immune system and can help the body to absorb iron. "Vitamin C also helps to keep blood vessels firm, offering protection from bruising. Blueberry juice and other products may be nutritious but often contain less fiber than the whole fruit, and added sugar or corn syrup may decrease their nutritional value. Consuming fresh, raw blueberries provides the most benefits; the average serving size of raw blueberries is one cup, which contains about 80 calories...

Blueberry consumption is beneficial for hepatic diseases....

We know that blueberry has many chemicals such as anthocyanins, proanthocyanidins, resveratrol, flavonols and tannins and how blueberry inhibit mechanisms of cancer cell development and inflammation in vitro. Similar to red grape, some blueberry species contain in their skins significant levels of resveratrol a phytochemical. 

Now research team led by Ming-Liang Cheng, MD, from Department of Infectious Diseases, Guiyang Medical College, Guiyang,  have found that blueberries could reduce liver indices, serum levels of hyaluronic acid and alanine aminotransferase, and increase levels of superoxide dismutase and decrease levels of malondialdehyde in liver homogenates compared with the model group.  Meanwhile, the stage of hepatic fibrosis was significantly weakened. Blueberries increased the activity of glutathione-S-transferase in liver homogenates and the expression of Nrf2 and Nqo1 compared with the normal group, but there was no significant difference compared with the model group. 

The authors suggest that blueberry consumption is beneficial for hepatic diseases (including fibrosis)....

I read an article in the same lines, where in the  researchers from Miyazaki prefecture of southern Japan and University of Miyazaki, screened nearly 300 different agricultural products for potential compounds that suppress HCV replication and uncovered a strong candidate in the leaves of rabbit-eye blueberry (native to the southeastern US). They purified the compound and identified it as proanthocyandin (a polyphenol similar to the beneficial chemicals found in grapes and wine). While proanthocyandin can be harmful, Kataoka and colleagues noted its effective concentration against HCV was 100 times less than the toxic threshold. The researchers are  hoping to explore the detailed mechanisms of how this chemical stops HCV replication....
