High Meat Consumption Linked to Heightened Cancer Risk on Yahoo! Health
2007.12.11
"... "This is the largest study to look at the effect of red and processed meat on multiple cancer sites, including rarer cancers, such as laryngeal and liver cancer."...For the study, red meats included beef, pork and lamb. Processed meats included bacon, red-meat sausage, poultry sausage, luncheon meats, cold cuts, ham, regular hot dogs and low-fat hot dogs...elevated risks for colorectal and lung cancer with high consumption of both meat types along with borderline higher risks for advanced prostate cancer. High red meat intake was also associated with increased risk of esophageal and liver and a borderline increased risk for laryngeal cancer. And high processed meat consumption also was associated with borderline increased risk for bladder cancer and myeloma, a kind of bone cancer. In addition, both red meat and processed meat consumption were associated with increased pancreatic cancer risk in men, but not women...Meats are a source of saturated fat and iron, both of which have been linked to cancer, and also the source of several compounds that are known to affect cell development, they added...Cooking at high temperatures might also contribute to cancer risk, Cross added."Heterocyclic amines and polycyclic aromatic hydrocarbons are formed when meats are cooked well-done by high temperature cooking methods, such as barbecuing,"..."

Aging Gracefully Requires Taking Out The Trash - ScienceDaily

"Suppressing a cellular cleanup-mechanism known as autophagy can accelerate the accumulation of protein aggregates that leads to neural degeneration...Boosting autophagy in the nervous system of fruit flies prevented the age-dependent accumulation of cellular damage in neurons and promoted longevity..."suggests there is an age-dependent suppression of autophagy that may be a contributing factor for human neurodegenerative disorders like Alzheimer's disease"...The age-related accumulation of proteins and lipids damaged by chemically aggressive forms of oxygen is considered by most in the geriatrics field to be a normal part of the aging process. As a result in most age-associated diseases, such as Alzheimer's, damaged proteins accumulate in excessive amounts, which leads to progressive cell death in the brain...When the researchers kept the neuronal levels of Atg8a high, the genetically engineered flies were spared the ravages of time. Promoting the pathway not only prevented the accumulation of protein aggregates but also significantly extended the average lifespan. "Our experiments show for the first time genetically that autophagy can sequester and eliminate misfolded and damaged proteins, which accumulate in neurons as normal part of the aging process," says Simonsen...Insulin signaling and caloric restriction are two major determinants of longevity and they also impact the activity level of autophagy. Therefore, regulating autophagy, the pathway that directly does the cleanup work, may be the key factor in controlling the aging process..."By maintaining the expression of a rate-limiting autophagy gene in the aging nervous system there is a dramatic extension of lifespan and resistance to age-associated oxidative stress," says Finley."

"...Flies that ate a diet rich with Rhodiola rosea, an herbal supplement long used for its purported stress-relief effects, lived on an average of 10 percent longer than fly groups that didn’t eat the herb...“Although this study does not present clinical evidence that Rhodiola can extend human life, the finding that it does extend the lifespan of a model organism, combined with its known health benefits in humans, make this herb a promising candidate for further anti-aging research,” said Mahtab Jafari...the UC Irvine researchers fed adult fruit fly populations diets supplemented at different dose levels with four herbs known for their anti-aging properties. The herbs were mixed into a yeast paste, which adult flies ate for the duration of their lives. Three of the herbs – known by their Chinese names as Lu Duo Wei, Bu Zhong Yi Qi Tang and San Zhi Pian – had no effect on fruit fly longevity, while Rhodiola was found to significantly reduce mortality. On average, Rhodiola increased survival 3.5 days in males and 3.2 days in females...Jafari said she is evaluating the molecular mechanism of Rhodiola by measuring its impact on energy metabolism, oxidative stress and anti-oxidant defenses in fruit flies. She is also beginning studies in mice and in mouse and human cell cultures. These latter studies should help understand the benefits of Rhodiola seen in human trials..."

"A chemical found in many plastic products used in households caused accelerated breast development and genetic changes in newborn female lab rats, a condition that might predispose the animals to breast cancer later in life...Butyl benzyl phthalate (BBP) is commonly used to soften polymers and plastics. It's found in everything from plastic pipes, vinyl floor tiles and carpet backing to lipstick. BBP has also been found to be an endocrine disruptor, which mimics the effect of hormones. Endocrine disruptors are known to damage wildlife and have also been implicated in reduced sperm counts and neurological problems in humans..."Our study is the first one demonstrating that exposure to this compound (BBP) soon after birth results in alterations in the expression of genes present in the mammary gland," said lead researcher Dr. Jose Russo... in March, a study published in the journal Environmental Health Perspectives suggested that exposure to phthalates could be fueling the obesity epidemic by contributing to abdominal obesity and insulin resistance in men."

Exercise pill hope for depression
Exercise pill hope for depression - BBC News
2007.12.05
"While the link between exercise and improved mood is well known, the reasons behind it are not fully understood. The latest research focuses on an area of the brain called the hippocampus, which is already established as a target for antidepressant drugs. The team developed a test to see which genes in this region were made more active during exercise, and highlighted one called VGF. This gene is linked to a "growth factor" chemical involved in the development of nerve cells. This fitted with their theory that, for depression to lift, changes in the actual structure and links between brain cells are needed, not just changes in the chemicals surrounding the cells. The next step was to make a version of that chemical, and to test it on mice, where it showed an effect on their behaviour that roughly equated to antidepressant effects in humans. The researchers believe that a drug based on VGF could offer "possibly even superior efficacy" to current antidepressants. Marcus Roberts, Head of Policy at Mind, said that, currently, the use of exercise as a treatment for mental health problems should be recommended by doctors."Mind has long recommended physical exercise as a way of improving mental wellbeing, and many people who experience mental distress have told us that exercise has hugely benefited their mental health. "Our own research has shown that outdoor exercise can decrease feelings of depression and increase self-esteem by inspiring a sense of achievement - the evidence is growing that this should be treated as a clinically valid treatment."

Although keep in mind that folic acid has been linked to an increase in cancer. Key quote - "Exposure to high intakes of folic acid in early life and young adulthood may provide life-long protection from the tendency for cancer formation in different organs, such as the large intestines, whereas such exposures later in life, when cell damage has occurred, can spur on the advance of the tumor."
So what's the answer? Eat the natural form - folate, in your diet, and skip the supplement Folic acid. "Folic acid is a synthetic form of folate, a B vitamin found in a wide variety of foods including liver and green leafy vegetables. Folates are metabolised in the gut, whereas in a paper to be published in the British Journal of Nutrition in October IFR scientists suggest that folic acid is metabolised in the liver. The liver is an easily saturated system, and fortification could lead to significant unmetabolised folic acid entering the blood stream, with the potential to cause a number of health problems."

Fitness level is predictor of longevity
Fitness Level, Not Body Fat, May Be Stronger Predictor Of Longevity For Older Adults ScienceDaily

"Adults over age 60 who had higher levels of cardiorespiratory fitness lived longer than unfit adults, independent of their levels of body fat... Fit participants had lower death rates than unfit participants within each stratum of adiposity, except for two of the obesity groups. In most instances, death rates for those with higher fitness were less than half of rates for those who were unfit..."Our data provide further evidence regarding the complex long-term relationship among fitness, body size, and survival. It may be possible to reduce all-cause death rates among older adults, including those who are obese, by promoting regular physical activity, such as brisk walking for 30 minutes or more on most days of the week (about 8 kcal/kg per week), which will keep most individuals out of the low-fitness category. Enhancing functional capacity also should allow older adults to achieve a healthy lifestyle and to enjoy longer life in better health.""
