Broccoli Could Reverse The Heart Damaging Effects Of Diabetes

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.

"women with the highest flavonol intake were 37 percent less likely to have ovarian cancer than women with the lowest flavonol intake...High intake of isoflavones cut ovarian cancer risk by 49 percent...Isoflavones are found in tea and soy foods, both of which have been linked to a lower ovarian cancer risk, possibly due to isoflavones' estrogen-blocking effects, Rossi and her colleagues note...Flavonols are found in many fruits and vegetables, they add. Adjusting the findings for women's fruit and vegetable intake didn't change the relationship between flavonol intake and ovarian cancer risk, the researchers note, suggesting that "flavonols may have a distinct role in explaining the effect of fruit and vegetable against ovarian cancer.""

Use Of Cleaning Products During Pregnancy Increases Risk Of Asthma In Young Children

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”."

Previous studies by others have shown that these proteins can block certain receptors in the GI tract that are the main attachment sites for E. coli, Helicobacter pylori and other disease-causing microbes, thereby preventing infection. By contrast, since cow's milk lacks these protein variants, it may not offer the same disease protection..."

Spices May Protect Against Consequences Of High Blood Sugar

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..."
