Broccoli Could Reverse The Heart Damaging Effects Of Diabetes: "ScienceDaily (Aug. 26, 2008) — Researchers have discovered eating broccoli could undo the damage caused by diabetes to heart blood vessels...a broccoli compound called Sulforaphane. This compound can encourage the body to produce more enzymes to protect the vessels, as well as reduce high levels of molecules which cause significant cell damage...Past studies have shown that a diet rich in vegetables – particularly brassica vegetables such as broccoli – is linked to decreased risk of heart disease and stroke...The results of the study showed that Sulforaphane reversed this increase in ROS by 73 per cent...Sulforaphane activated a protein in the body called nrf2, which protects cells and tissues from oxidative stress by activating protective antioxidant and detoxifying enzymes. The study showed the presence of Sulforaphane in human microvascular cells doubled the activation of nrf2..."

Black Raspberries Slow Cancer By Altering Hundreds Of Genes
Black Raspberries Slow Cancer By Altering Hundreds Of Genes: "ScienceDaily (Aug. 27, 2008) — New research strongly suggests that a mix of preventative agents, such as those found in concentrated black raspberries, may more effectively inhibit cancer development than single agents aimed at shutting down a particular gene...Researchers at the Ohio State University Comprehensive Cancer Center examined the effect of freeze-dried black raspberries on genes altered by a chemical carcinogen in an animal model of esophageal cancer...The carcinogen affected the activity of some 2,200 genes in the animals’ esophagus in only one week, but 460 of those genes were restored to normal activity in animals that consumed freeze-dried black raspberry powder as part of their diet during the exposure...“We have clearly shown that berries, which contain a variety of anticancer compounds, have a genome-wide effect on the expression of genes involved in cancer development,”...Stoner notes that black raspberries have vitamins, minerals, phenols and phytosterols, many of which individually are known to prevent cancer in animals...“Freeze drying the berries concentrates these elements about ten times, giving us a power pack of chemoprevention agents that can influence the different signaling pathways that are deregulated in cancer,” he says...“What’s emerging from studies in cancer chemoprevention is that using single compounds alone is not enough,” Stoner says. “And berries are not enough. We never get 100 percent tumor inhibition with berries. So we need to think about another food that we can add to them that will boost the chemopreventive activities of berries alone.”..."
Another part of the equation must surely be the chemoprevention found in cruciferous vegetables - such as sulforaphanes in broccoli.

Use Of Cleaning Products During Pregnancy Increases Risk Of Asthma In Young Children: "ScienceDaily (Aug. 7, 2008) — Women who use a lot of household cleaning products when they are pregnant, or shortly after giving birth, are increasing their child’s risk of developing asthma. That’s according to the Avon Longitudinal Study of Parents of Children (ALSPAC, also known as Children of the Nineties), that recruited over 13,000 children from before birth and has followed them to post 16...early life exposure to the chemicals contained in household cleaning products was linked to a 41% increase in a child’s chances of developing asthma by the age of 7 years...“Previous research has shown that a child’s risk of developing asthma is lower if he or she is exposed to bacteria or bacterial products (endotoxins) in early life (‘hygiene hypothesis’), probably because it assists in the development of a child’s immune system...However, our research suggests that one possible mechanism for this hypothesis may involve the chemicals found in domestic cleaning products. These chemicals have been linked to increased risk of asthma with additional evidence from studies of workers who have exposure to cleaning chemicals”."

Spices May Protect Against Consequences Of High Blood Sugar: "ScienceDaily (Aug. 7, 2008) — Herbs and spices are rich in antioxidants, and a new University of Georgia study suggests they are also potent inhibitors of tissue damage and inflammation caused by high levels of blood sugar...when blood sugar levels are high, a process known as protein glycation occurs in which the sugar bonds with proteins to eventually form what are known as advanced glycation end products, also known as AGE compounds. The acronym is fitting because these compounds activate the immune system, resulting in the inflammation and tissue damage associated with aging and diabetes...The researchers found a strong and direct correlation between the phenol content of common herbs and spices and their ability to inhibit the formation of AGE compounds. Spices such as cloves and cinnamon had phenol levels that were 30 percent and 18 percent of dry weight, respectively, while herbs such as oregano and sage were eight and six percent phenol by dry weight, respectively. For comparison, blueberries – which are widely touted for their antioxidant capabilities – contain roughly five percent phenol by dry weight..."

Hoping Two Sirtris Drugs Carry a Side Effect - Longer Life
Hoping Two Drugs Carry a Side Effect - Longer Life - NYTimes.com:
2008.07.22
"...The new drugs are called sirtuin activators, meaning that they activate an enzyme called sirtuin. The basic theory is that all or most species have an ancient strategy for riding out famines: switch resources from reproduction to tissue maintenance. A healthy diet but with 30 percent fewer calories than usual triggers this reaction in mice and is the one intervention that reliably increases their life span. The mice seem to live longer because they are somehow protected from the usual diseases that kill them...The Sirtris drug being tested in diabetic patients is a special formulation of resveratrol that delivers a bloodstream dose five times as high as the chemical alone. This drug, called SRT501, has passed safety tests and, at least in small-scale trials, has reduced the patients’ glucose levels...The other drug is a small synthetic chemical that is a thousand times as potent as resveratrol in activating sirtuin and can be given at a much smaller dose. Safety tests in people have just started, with no adverse effects so far...The hope is that activating sirtuins in people would, like a calorically restricted diet in mice, avert degenerative diseases of aging like diabetes, heart disease, cancer and Alzheimer’s. There is no Food and Drug Administration category for longevity drugs, so if the company is to submit a drug for approval, it needs to be for a specific disease...Dr. Christoph Westphal, the chief executive of Sirtris, said of the potential of the drugs, “I think that if we are right, this could extend life span by 5 or 10 percent.”...Resveratrol seems to exert many influences on the body, some of which are not exerted through sirtuin. “None of us should be naïve enough to think resveratrol won’t have multiple effects, including some you don’t want,” Dr. Vallance said...According to a study published on July 3 in the journal Cell Metabolism by Dr. Sinclair and Dr. Rafael de Cabo of the National Institute on Aging, resveratrol given to aging mice reduced their cataracts, strengthened their bones, improved coordination and enhanced their health in several other ways. Yet despite their better health, the mice lived no longer than usual..."

Stomach Bug Appears To Protect Kids From Asthma
Stomach Bug Appears To Protect Kids From Asthma, Says New Study: "ScienceDaily (July 20, 2008) — A long-time microbial inhabitant of the human stomach may protect children from developing asthma, according to a new study among more than 7,000 subjects led by NYU Langone Medical Center researchers. Helicobacter pylori, a bacterium that has co-existed with humans for at least 50,000 years, may lead to peptic ulcers and stomach cancer. Yet, kids between the ages of 3 and 13 are nearly 59 percent less likely to have asthma if they carry the bug, the researchers report...Asthma has been rising steadily for the past half-century. Meanwhile H. pylori, once nearly universal in humans, has been slowly disappearing from developed countries over the past century due to increased antibiotic use, which kills off the bacteria, and cleaner water and homes...The rise in asthma over the past decades, Dr. Blaser says, could stem from the fact that a stomach harboring H. pylori has a different immunological status from one lacking the bug. When H. pylori is present, the stomach is lined with immune cells called regulatory T cells that control the body's response to invaders. Without these cells, a child can be more sensitive to allergens..."Our hypothesis is that if you have Helicobacter you have a greater population of regulatory T-cells that are setting a higher threshold for sensitization," Dr. Blaser explains. "For example, if a child doesn't have Helicobacter and has contact with two or three cockroaches, he may get sensitized to them. But if Helicobacter is directing the immune response, then even if a child comes into contact with many cockroaches he may not get sensitized because his immune system is more tolerant."...In other words, the presence of the bacteria in the stomach may influence how a child's immune system develops: if a child does not encounter Helicobacter early on, the immune system may not learn how to regulate a response to allergens. Therefore, the child may be more likely to mount the kinds of inflammatory responses that trigger asthma..."

Regular Walking Protects The Masai -- Who Eat High Fat Diet -- From Cardiovascular Disease
Regular Walking Protects The Masai -- Who Eat High Fat Diet -- From Cardiovascular Disease: "ScienceDaily (July 20, 2008) — Scientists have long been puzzled by how the Masai can avoid cardiovascular disease despite having a diet rich in animal fats. Researchers at Karolinska Institutet believe that their secret is in their regular walking...their results show that the Masai not only have a diet richer in animal fat than that of the other subjects, but also run the lowest cardiovascular risk, which is to say that they have the lowest body weights, waist-measurements and blood pressure, combined with a healthy blood lipid profile...What sets the Masai lifestyle apart is also a very high degree of physical activity. The Masai studied expended 2,500 kilocalories a day more than the basic requirement, compared with 1,500 kilocalories a day for the farmers and 891 kilocalories a day for the urbanites. According to the team, most Westerners would have to walk roughly 20 km a day to achieve the Masai level of energy expenditure...The scientists believe that the Masai are protected by their high physical activity rather than by some unknown genetic factor..."

Study: Low-carb diet best for weight, cholesterol
Study: Low-carb diet best for weight, cholesterol on Yahoo! Health:
2008.07.17
"ATLANTA - The Atkins diet may have proved itself after all: A low-carb diet and a Mediterranean-style regimen helped people lose more weight than a traditional low-fat diet in one of the longest and largest studies to compare the dueling weight-loss techniques...A bigger surprise: The low-carb diet improved cholesterol more than the other two. Some critics had predicted the opposite...all three approaches — the low-carb diet, a low-fat diet and a so-called Mediterranean diet — achieved weight loss and improved cholesterol...The study is remarkable not only because it lasted two years, much longer than most, but also because of the huge proportion of people who stuck with the diets — 85 percent...Average weight loss for those in the low-carb group was 10.3 pounds after two years. Those in the Mediterranean diet lost 10 pounds, and those on the low-fat regimen dropped 6.5...But the low-carb approach seemed to trigger the most improvement in several cholesterol measures, including the ratio of total cholesterol to HDL, the "good" cholesterol...The ratio declined by 20 percent in people on the low-carb diet, compared to 16 percent in those on the Mediterranean and 12 percent in low-fat dieters...The new study's results favored the Atkins-like approach less when subgroups such as diabetics and women were examined...Among the 36 diabetics, only those on the Mediterranean diet lowered blood sugar levels. Among the 45 women, those on the Mediterranean diet lost the most weight... "I think these data suggest that men may be much more responsive to a diet in which there are clear limits on what foods can be consumed," such as an Atkins-like diet, said Dr. William Dietz, of the Centers for Disease Control and Prevention..."

Dark Chocolate, Cocoa May Cut Blood Pressure in Overweight Adults
Study: Dark Chocolate, Cocoa May Cut Blood Pressure in Overweight Adults: WebMD
"July 11, 2008 -- Cocoa, either in a dark chocolate bar or as a hot drink, may reduce blood pressure in overweight adults...The researchers -- who included David L. Katz, MD, MPH, of the Yale Prevention Research Center -- gave some of the participants a dark chocolate bar containing 22 grams of cocoa. Other participants got a bar containing no cocoa...Before-and-after blood pressure and ultrasound tests showed better blood pressure and better blood vessel function after participants ate the dark chocolate bar, compared to the cocoa-free bar...Likewise, blood pressure and blood vessel function improved after participants drank two cups of cocoa, compared with drinking a beverage containing no cocoa...How the cocoa drink was sweetened mattered. When it contained sugar, blood pressure and blood vessel function didn't improve as much as when the cocoa was sugar-free..."

8 Burning Questions About Sunscreens
8 Burning Questions About Sunscreens: WebMD
2008.0.08
"Two ingredients favored by EWG scientists are zinc oxide and titanium dioxide, for two reasons, Sutton says. 'They protect us over this broad range of ultraviolet A (UVA) and UVB.' And these ingredients don't tend to break down as easily as other sunscreen ingredients, according to the EWG...
Sunscreens Can Damage Skin, Researchers Find:ScienceDaily (Aug. 29, 2006)
"three UV filters (octylmethoxycinnamate, benzophenone-3 and octocrylene), which are approved by the Food and Drug Administration and widely used in sunscreens, generate ROS in skin themselves when exposed to ultraviolet radiation, thus augmenting the ROS that is naturally produced. The researchers note that the additional ROS are generated only when the UV filters have penetrated into the skin and, at the same time, sunscreen has not been reapplied to prevent ultraviolet radiation from reaching these filters."

"Two ingredients favored by EWG scientists are zinc oxide and titanium dioxide, for two reasons, Sutton says. 'They protect us over this broad range of ultraviolet A (UVA) and UVB.' And these ingredients don't tend to break down as easily as other sunscreen ingredients, according to the EWG...
Sutton thinks some ingredients are definitely hazardous, including oxybenzone. "We have animal studies that indicate we should be concerned about hormone disruption," she says. "Oxybenzone is found to have weak estrogenic effects in fish."
What some experts suspect happens is that the body interprets the presence of the chemical as some sort of hormone. "It could be turning on or off certain functions," she says. "The hormonal balance is becoming disrupted."
In laboratory studies, some sunscreen ingredients, including Padimate-O and Ensulizole, have been linked to cell mutations that can be linked to cancer, Sutton says."

Cancer Preventive Properties Identified In Resveratrol
Cancer Preventive Properties Identified In Resveratrol, Found In Red Wine, Red Grapes:
"ScienceDaily (July 7, 2008)
Early laboratory research has shown that resveratrol, a common dietary supplement, suppresses the abnormal cell formation that leads to most types of breast cancer, suggesting a potential role for the agent in breast cancer prevention..."This is dramatic because it was able to be done with fairly low concentrations of resveratrol to stop the formation of these DNA adducts in the cells we studied," said Rogan. Although researchers experimented with up to 100 µmol/L of resveratrol, the suppression of DNA adducts was seen with 10 µmol/L. A glass of red wine contains between 9 and 28 µmol/L of resveratrol...The researchers also found that resveratrol suppressed the expression of CYP1B1 and the formation of 2,3,7,8-Tetrachlorodibenzo-p-dioxin, two known risk factors for breast cancer..."

Red Wine Reduces Harm From Red Meat
Tummy's Taste For Red Wine With Red Meat:
"ScienceDaily (July 3, 2008)
What happens when red wine meets red meat? If the rendezvous happens in the stomach, scientists in Israel are reporting, wine's bounty of healthful chemical compounds may thwart formation of harmful substances released during digestion of fat in the meat...Joseph Kanner and colleagues point out that scientists attribute wine's health benefits, including protection against cancer and heart disease, to its high levels of polyphenols, powerful antioxidants found in fruits and vegetables...The researchers found an explanation in experiments with laboratory rats fed either red meat or meat combined with red wine concentrate. Wine concentrate substantially reduced formation of two byproducts of fat digestion, malondialdehyde and hydroperoxide, which are toxic to cells. The researchers say the stomach acts as a "bioreactor" that facilitates the beneficial effects of polyphenols. The polyphenols work not only to prevent generation of cytotoxic compounds, but also as compounds which prevent the absorption of cytotoxic compounds from the gastrointestinal tract into the blood stream."

Herbal Remedy Pau d'Arco (Tabebuia impetiginosa) may reduce Obesity
Herbal Remedy Reduces Obesity And Heart Disease?:
"ScienceDaily (July 8, 2008)
With unprecedented levels of obesity across the Western world, and incidence of associated heart disease, cancer and diabetes rising, there is a major drive to find new treatments. Scientists from Germany have recently discovered that extracts of a traditional herbal remedy derived from Tabebuia impetiginosa can act to delay the absorption of dietary fat in animal models...Dr Roos and his team have shown that Tabebuia extract can reduce levels of triglycerides, a breakdown product of fat, in rats after they have been fed a fatty meal. "This result shows the extract may have a potential use in treating obesity,"...Although it is clear that Tabebuia extract can act to inhibit the absorption of dietary fat, the scientists have not yet identified the exact compounds within the extract that are responsible for the effects."
If you buy Pau d'Arco make sure you are buying it from a sustainable source. The tree is in danger and the rampant logging of the tree has also aided in rainforest destruction... so choose carefully. Nature's Way claims to be good on these counts. I have no connection with them.
