|Raspberry is the fruit of Rubus idaeus, a shrub of the Rosaceae which is a medium-sized family of flowering plants. Its nutritional properties are close to those of strawberry. The berry also contains contain vitamin E as well as certain mineral salts such as potassium. But the berry has more than that; this is why you can find some people dare to claim “black raspberry cancer treatment.”
Raspberry Cancer Benefits
Raspberry is much more than just a delicious summer fruit. This fruit also offers many interesting nutritional intake which can help your body to get rid of diseases, while keeping you in shape. They are full of a variety of important nutrients and have a low glycemic index. So rich in health benefits, raspberry is a nearly perfect food that should be eaten very often.
Raspberry is known for being richest in ellagic acid, a powerful an antioxidant polyphenol found in many fruits and vegetables (chestnuts, raspberries, strawberries, cranberries, walnuts, pecans, pomegranates…) which shown to prevent and slow cancer development. It also contains antioxidant anthocyanins and flavonol quercetin with a rate of 3 mg / 100 g, which is not only anticancer but also a good facilitator of intestinal transit. The black species are even more powerful; this is the reason of some claims “black raspberry cancer prevention” you can find all over the internet.
Anti-cancer benefits of raspberries have been long attributed to their antioxidant properties and anti-inflammatory phytonutrients. In animal studies involving breast, cervix, colon, esophagus and prostate, phytonutrients in raspberries have demonstrated to play a great role in decreasing oxidative stress and inflammation, thus modifying development or reproduction of cancer cells. But new “raspberry cancer research” has shown that anti-cancer properties may extend beyond their antioxidant and anti-inflammatory properties.
Phytonutrients in raspberries may be able to modify the signals that are sent to potential or pre-existing cancerous cells. In the case of existing cancer cells, phytonutrients like tannic acid, ellagic acid, may be able to reduce the number of cancer cells by sending signals that encourage the cancerous cells to self-destruct (programmed cell death, apoptosis) which cancer cells do not undergo.
But not all raspberries are the same when it comes to anti cancer benefits. A recent study has found some types of raspberries have a remarkably different phytochemistry as well as different biological activities. Extracts from Rubus rosifolius (also known as Rubus jamaicensis) showed greatest potential to inhibit the growth of cancerous cells, mostly in colon cancer, breast cancer, lung cancer, and stomach cancer. That is, although all raspberries provide great quantities of phytonutrients to fight cancer, Rubus jamaicensis is the champion.
But Rubus rosifolius is rare in certain areas in the United States, except in San Francisco neighborhoods where it produces a lot. It is native to rainforest and tall open forest of the Himalayas, East Asia, and eastern Australia. It is also found abundantly in the Brazilian states Minas Gerais, Rio de Janeiro and to the south as far as Rio Grande do Sul.
