Stroke takes an enormous toll on health. In fact, it’s the third leading cause of death in the US, according to the American Stroke Association. So imagine how much money Big Pharma could rake in if drug manufacturers came up with a medication that not only reduced the risk of having a stroke but slashed the risk of dying from a stroke in half. It turns out there’s a substance already on the market that does just that. Only, it isn’t an expensive prescription drug but a delicious, natural food — chocolate.
A report just released by Canadian scientists from McMaster University in Hamilton, Ontario, and the University of Toronto provides evidence that consuming chocolate regularly significantly reduces the odds of having a stroke. What’s more, if a person who eats chocolate does suffer a stroke, their risk of dying afterwards is almost half that of non-chocolate eaters.
The research team reached these conclusions after analyzing three studies for any links between chocolate intake and strokes. Although one study didn’t reveal any risk or benefit, two others did. A large study of 44,489 people showed that those who ate at least one serving of chocolate each week were 22 percent less likely to have a stroke than the research participants who didn’t indulge in chocolate.
Another study of 1,169 people found that when someone did experience a stroke, if they ate 50 grams of chocolate each week they were about 50 percent less likely to die afterwards than those who had strokes but didn’t eat chocolate. The researchers stated that chocolate’s abundant antioxidant content could be the key to its apparent stroke-protective effect.
“More research is needed to determine whether chocolate truly lowers stroke risk, or whether healthier people are simply more likely to eat chocolate than others,” study author Sarah Sahib, BScCA, of McMaster University, said in a statement to the media.
Historically, traditional healers have long contended that chocolate is good for body and spirit. For example, the ancient Aztecs and Mayans are believed to be the first people who drank a chocolate drink to help matters of the heart. And in recent years, scientists have found that some phytochemicals in chocolate can alter a person’s sense of well being, producing a lift similar to the feeling of being in love. As NaturalNews has previously reported (http://www.naturalnews.com/023499_c…), Harvard Medical School scientists have discovered that cocoa, which is the main component of chocolate, may literally be good for the heart — their research shows it could reduce the risk of heart disease and also cancer.

Blueberries Increase Memory

Although several studies involving laboratory animals have provided tantalizing clues that eating blueberries improves memory, could the delicious fruit actually help people retain their mental sharpness as they age? The good new appears to be “yes”. In fact, blueberries might even boost brain power. For the very first time, a study has found evidence that blueberry juice improves memory in humans.
For the research project, a team of scientists from the University of Cincinnati, the U.S. Department of Agriculture, and the Canadian Department of Agriculture worked with a group of volunteers in their 70s who suffered from early memory decline. Half the group drank the equivalent of two to two and 1/2 cups of blueberry juice every day for two months. As a control, a second group drank a different beverage that did not contain any blueberry juice.
After about eight weeks, the scientists conducted learning and memory tests to see if the research participants’ cognitive abilities had undergone any measurable changes. The results, which were recently published in the American Chemical Society’s (ACS) Journal of Agricultural and Food Chemistry, showed that the elders who had been regularly drinking blueberry juice demonstrated significant improvement in their mental faculties.
Lead researcher Robert Krikorian and colleagues concluded that eating blueberries, which are a rich source of antioxidants and phytochemicals, may help boost memory in the aged. Bottom line: the study establishes a basis for larger, comprehensive human clinical trials to further document how blueberries can be a powerful aid for keeping brains and thinking abilities healthy and strong into old age.
“These preliminary memory findings are encouraging and suggest that consistent supplementation with blueberries may offer an approach to forestall or mitigate neurodegeneration,” the researchers stated.
As NaturalNews has previously reported, blueberries have gained the attention of researchers studying a whole range of ways this remarkable fruit can protect and heal the body. For example, scientists at Rutgers University and the U.S. Department of Agriculture found in animal studies that a compound in blueberries called pterostilbene could prevent colon cancer (http://www.naturalnews.com/021951_b…).
In addition, another animal study revealed that blueberries can lower the levels of artery-clogging LDL (known as the “bad” cholesterol) as effectively as statin drugs, but without negative side effects.

Selenium and Omega-3s Prevent Colon Cancer
January 25, 2010

By S.L. Baker
When scientists gathered in Houston recently for the American Association for Cancer Research (AACR) Frontiers in Cancer Prevention Research Conference, they heard groundbreaking evidence about how colon cancer can be prevented. The new data wasn’t about drugs or surgery, either. Instead, two separate research groups concluded natural substances appear to protect from often deadly colon malignancies.
Colon cancer, which the American Cancer Society estimates is diagnosed in over 108,000 Americans each year, is intricately linked to adenomas, also called polyps. These lesions grow in the large bowel and start off as benign. However, they can turn into cancerous tumors and 70 to 80% of all cancers of the colon (the longest part of the large intestine) and rectum result from adenomas-turned-malignant.
So, in hopes of preventing future cancerous growths, polyps found during colonoscopies are snipped off and biopsied. Unfortunately though, pre-cancerous polyps often return. But scientists at the National Institute for Cancer Research in Genoa, Italy, conducted a long term study that shows the risk of pre-cancerous polyps (dubbed colorectal metachronous adenomas) coming back after they’ve been removed can be greatly reduced. The key? Taking specific antioxidants, including a selenium-based compound.
“Our study is the first intervention trial specifically designed to evaluate the efficacy of the selenium-based antioxidant compound on the risk of developing metachronous adenomas,” said Luigina Bonelli, M.D., head of the unit of secondary prevention and screening at the National Institute for Cancer Research, in a statement to the media.
40% reduced risk
The research team studied volunteers between the ages of 25 and 75 who had already had one or more colorectal adenomas removed. None of the participants were diagnosed with any additional colorectal disease, cancer or other life-threatening illness and none were taking vitamins or mineral supplements when the study began. The scientists randomly divided the 411 participants into two groups: those in one group received an inactive placebo and those in the second group took a daily antioxidant supplement containing a selenium compound (selenomethionnine 200 ug), zinc 30 mg, vitamin A 6,000 IU, vitamin C 180 mg and vitamin E 30 mg.
“Our results indicated that individuals who consumed antioxidants had a 40% reduction in the incidence of metachronous adenomas of the large bowel,” Bonelli said. “It is noteworthy that the benefit observed after the conclusion of the trial persisted through 13 years of follow up.”
Omega-3s help prevent colorectal cancer
Another study just released at the Frontiers in Cancer Prevention Research Conference — this one from the National Institute of Environmental Health Sciences in Research Triangle Park, North Carolina — found that omega-3 fatty acids, which are primarily found in cold water fish such as salmon, may be able to prevent colorectal cancer.
The scientists recruited 1,509 Caucasian participants (716 cancer cases and 787 controls) and 369 African-American participants (213 cancer cases and 156 controls). A validated food questionnaire was used to collect information on the frequency and amount of foods typically consumed by the research subjects in the past 12 months. Those who ate more long-chain omega-3 fatty acids had a significantly reduced risk of large bowel cancer. In fact, the highest intake was linked to an almost 40% decreased cancer risk. Unfortunately, the greatly reduced risk was only seen in white research subjects and the scientists are trying to figure out what might account for the racial disparity.
“Experimental data have shown benefits of long-chain omega-3 fatty acids in colorectal carcinogenesis, ranging from reduced tumor growth, suppression of angiogenesis and inhibition of metastasis,” research leader Sangmi Kim, Ph.D., said in a statement to the press. “Our finding of inverse association between dietary intakes of long-chain omega-3 fatty acids and distal large bowel cancer in white participants adds additional support to the hypothesis.”
These new studies linking natural substances to colon cancer prevention are part of a growing body of evidence indicating dietary measures can fight this kind of cancer successfully. For example, as NaturalNews has previously reported, the disease is primarily linked to the typical Western diet so avoiding processed food and trans fats can go far to prevent it. What’s more, blueberries have been shown to slash the risk of colon cancer by 57% and apples contain natural phytochemicals that have a protective effect against colon cancer too.

Mango – Preventing Growth of Colon and Breast Cancer Cells
January 21,2010
Natural News
By S. L. Baker
Take a bite of a juicy, sweet mango and you are experiencing a delicious taste enjoyed by countless people from ancient times until today. According to the Orlando-based National Mango Board (NMG), a mango industry-sponsored research, promotion and consumer information program, mangos are known to be rich in vitamins C and A, as well as fiber. However, because little has been documented about any specific health benefits of eating the fruit, NMB has commissioned a variety of scientific studies to investigate these issues.
So far, this research initiative has turned up an unexpected and groundbreaking discovery: in laboratory experiments in Texas A&M University’s AgriLife Research department mango fruit prevented or stopped cancer growth in certain breast and colon cell lines.
Food scientists Dr. Susanne Talcott and her co-researcher husband, Dr. Steve Talcott, used the five varieties of mangos (Kent, Francine, Ataulfo, Tommy/Atkins and Haden) most common in the US and specifically tested polyphenol extracts from the fruit on colon, breast, lung, leukemia and prostate cancer cells. Polyphenols are natural substances in plants that are antioxidants with the potential to protect the body from disease. The Talcotts zeroed in on evaluating polyphenolic compounds in mangos known as gallotannins, a class of natural bioactive compounds believed to help prevent or block the growth of cancer cells.
The results? The Talcotts’ experiments showed that the mango extract demonstrated some cancer fighting ability when tested on lung, leukemia and prostate cancer cells. But when tested on the most common breast and colon cancers, mango compounds were found to have even stronger anticancer abilities. In fact, the mango extract caused the breast and colon cancer cells to undergo apoptosis — programmed cell death.
“Additionally, we found that when we tested normal colon cells side by side with the colon cancer cells, the mango polyphenolics did not harm the normal cells,” Dr. Susanne Talcott said in a statement to the press. “That is a general observation for any natural agent, that they target cancer cells and leave the healthy cells alone, in reasonable concentrations at least.”
The researchers documented that the cancer cell cycle (the division process cells go through) was interrupted by mango extract. This is crucial information, Suzanne Talcott said in a press statement, because it could explain a possible mechanism for how the cancer cells are prevented or stopped by phytochemicals in mangos. “For cells that may be on the verge of mutating or being damaged, mango polyphenolics prevent this kind of damage,” she explained.
The scientists have conducted additional research on the colon cancer cell lines because mangos contain small molecules that are readily absorbed in the colon as well as larger molecules that are not absorbed and remain present longer in the colon. Those facts could potentially make eating mangos a potent way to help prevent colon cancer. In fact, the Talcotts are hoping to next conduct a small clinical trial to see if mangos can prevent colon cancer in people at high risk for a malignancy because they have increased inflammation in their intestines.

Eating Pomegranates Reduces Risk of Breast Cancer

An acid found in pomegranates appears to block aromatase, an enzyme that converts androgen to estrogen, a hormone that plays a role in the development of breast cancer, the researchers wrote in the journal Cancer Prevention Research.
“We identified some of these chemicals in pomegranates that actually have properties that can suppress aromatase,” researcher Shiuan Chen, of the City of Hope cancer research and treatment center in Duarte, California, said in a telephone interview.
Many women who have had breast cancer take medicines called aromatase inhibitors — such as Pfizer’s Aromasin, Novartis’ Femara and AstraZeneca Plc’s Arimidex — to keep estrogen from feeding tumors.
Chen and colleagues studied whether compounds, or phytochemicals, in pomegranates can suppress aromatase and ultimately block cancer growth. They found that 10 natural compounds in the fruit may potentially prevent estrogen-related breast cancer.
Chen said the compounds would not be a replacement for aromatase inhibitors.
“We do not recommend people start taking this as a replacement for the AI’s,” Chen said. “They (pomegranate compounds) are not as potent as the real drugs so we think that the interest probably is more on the prevention end rather than in a therapeutic purpose.”
Other researchers not associated with the study told the journal that the results are promising, and suggested more studies involving animals and humans were needed to confirm the findings.
“It’s not clear that these levels could be achieved in animals or in humans because the (compounds) are not well absorbed into blood when provided in the diet,” said Gary Stoner of Ohio State University.
Dr. Powel Brown, an oncologist at the University of Texas, said in a statement that future studies should focus on testing pomegranate juice for its effect on estrogen levels, menopausal symptoms, breast density or even as a cancer preventive agent.
More than 400,000 women die from breast cancer globally every year. About 75 percent of breast cancers are estrogen-receptor positive, meaning they are fed by estrogen.
Previous research has shown that pomegranate juice is rich in antioxidants — vitamins and other substances — that may help prevent diseases such as cancer, heart disease and Alzheimer’s disease.
Color My World – Phytochemicals in Fruits Good for You
November 06, 2009

Phenolics. Flavonoids. Carotenoids. Quercetin. Phloridzin. What do these scientific names have in common? They are all types of phytonutrients, also called phytochemicals, found in fruits, vegetables, grains, legumes, nuts, and teas. And they may decrease the risk of not only minor illnesses like colds but also many of the major killers on the planet — including cancer and heart disease. Scientists have only identified a few of the suspected vast number of these natural compounds in foods that protect and build health. But two facts are clear. First, most Americans don’t get enough phytonutrients in their daily diet for optimum health and, second, there’s an easy strategy to boost your phytonutrient intake — simply eat a mix of more naturally colorful foods.
The recently released Phytonutrient Report, sponsored by the supplement company Nutrilite, used National Health and Nutrition Examination Surveys (NHANES) and USDA data to analyze what people in the U.S. typically eat each day. Because the same compounds that give plant foods various colors are related to phytonutrient content, the report divided consumption into five categories of colors — green, red, blue/purple, yellow/orange and white.
For example, the phytonutrients, isothiocyanate, lutein and isoflavones are known to be abundant in green foods such as spinach and broccoli and lycopene and ellagic acid are found in red fruits and vegetables like watermelon and tomatoes. White plant foods like onions and garlic are rich in allicin and quercetin. Anthocyanidins and resveratrol are found in purple and blue foods like grapes and blueberries while alpha-carotene, beta-carotene, hesperitin and beta-cryptoxanthin are most often in yellow/orange foods such as carrots and oranges.
The Phytonutrient Report concludes there is a phytonutrient gap in every color classification. Specifically, 88% of Americans are eating too few foods in the blue/purple category, 79% are missing out on an adequate intake of yellow and orange foods, and 78% don’t have enough red veggies and fruits in their diets. In addition, 69% lack enough daily green plant foods and 86% lack enough white plant foods.
Osteoporosis Treatments Using Fern Plant
October 30, 2009
Natural news

An illustration from an 1887 book depicts the fabled “Vegetable Lamb of Tartary” as a plant with a tiny furry animal coming out of a long stalk. The reason? This wooly tree fern was once believed to literally produce sheep. That legend no doubt came about because the plant has masses of wool-like fibers that emerge on top. It grows in mountainous areas of China, northeast India, Malaysia, Myanmar, Indonesia, Thailand, Vietnam, and Japan and has long been used in Asian medicine to treat rheumatism, muscle aches and pains, nerve pain, and body aches during pregnancy.
Now scientists studying the plant, known by its botanical name Cibotium barmoetz (C. barmoetz), have found evidence it contains several powerful phytochemicals. And these natural compounds could treat the bone-thinning disorder known as osteoporosis.
A research team from the Vietnam Academy of Science and Technology (VAST) in Hanoi, Viet Nam; Chungnam National University in Daejeon, South Korea, and the Kyungpook National University’s Skeletal Diseases Genome Research Center in Daegu, South Korea, analyzed the so-called “vegetable lamb plant” as part of a larger study of Vietnamese plant-based folk medicine. In all, scientist Young Ho Kim and his colleagues isolated eight compounds from an extract of C. barmoetz rhizomes. Rhizomes are horizontal underground stems that are involved in the vigorous reproduction of these fern plants. They send new roots out of their nodes and into the soil, resulting in new stems shooting up to the surface.
As reported in the October issue of the Journal of Natural Products, published by the American Chemical Society (ACS), four of these compounds showed remarkable properties when tested in the lab. They halted the formation of 97% of osteoclast cells (which break down bone) in laboratory cultures without harming other cells. That’s important because normal strong bones depend on a healthy balance between osteoblasts (cells that build bones) and osteoclasts. If the production of osteoclasts is increased or if osteoblast production is decreased, then bones can become brittle and weak. So the C. barmoetz compounds might be able to treat osteoporosis by reducing an over-abundance of osteoclasts, thereby normalizing bone marrow function.
Osteoporosis is characterized by low bone mass and deterioration of bone tissue which can make you susceptible to fractures. According to the National Osteoporosis Foundation, 10 million people in the US now have osteoporosis (which literally means “porous bones”) and almost 34 million more are estimated to have low bone mass.

White Tea Fights Obesity
September 3, 2009
Natural News
By David Gutierrez
Regular consumption of white tea might help prevent obesity and encourage weight loss, according to a study conducted by researchers from the German health food company Beiersdorf AG and published in the journal Nutrition and Metabolism.
“In the industrialized countries, the rising incidence of obesity-associated disorders including cardiovascular diseases and diabetes constitutes a growing problem,” said Beiersdorf nutritionist Marc Winnefeld. “We’ve shown that white tea may be an ideal natural source of slimming substances.”
Made from the same plant as other true teas such as green, black or oolong tea, white tea is brewed from undamaged leaves that have been only lightly steamed, rather than being fermented or allowed to wilt or bruise. It is typically made with the youngest leaves of the plant and may also contain unopened tea buds, which are covered with a downy white hair that gives the tea variety its name.
Researchers exposed laboratory-grown human fat cells (adipocytes) to an extract of white tea. They found that exposure to the tea extract led a decrease in activity among the genes associated with new adipocyte formation, “while also prompting existing adipocytes to break down the fat they contain.”
Scientists believe that because it is the least processed variety of tea, white tea contains the highest levels of health-promoting phytochemicals. The Beiersdorf researchers believe that methylxanthines and epigallocatechin-3-gallate (EGCG) contributed to the effects seen in the current study.
The earliest evidence of white tea consumption dates to the Ming Dynasty, between 1366 and 1644 CE. It is now more popular in Western countries than in China. To prevent it from becoming bitter, white tea should not be brewed at any temperature higher than 180 degrees Fahrenheit (80C). The ideal tea to water ratio, according to experts, is 1.5 teaspoons per 200 milliliters (6.7 fluid ounces).
Previous research has linked white tea to lower blood pressure, increased bone strength and a reduced risk of cancer.
