Walnuts Slow Prostate Cancer Growth
According to the American Cancer Society, prostate cancer is the second most common form of cancer in men. And it's estimated that the disease will claim the lives of nearly 30,000 suffers in 2014 alone. Now a new study conducted by researchers at UC Davis and published in the Journal of Medicinal Food is reporting that walnuts appear to the ability to slow the growth of prostate cancer according to a recent study. Previous studies have indicated that walnuts have the ability to slow prostate tumor size, but researchers decided to test whether or not walnuts had the ability to reduce the actual growth of the cancer itself. After an eighteen week mouse model study in which groups of mice received either walnuts, walnut oil, or a fatty substance with a similar omega-3 profile it was determined that not only did the walnuts and walnut oil slow cancer cell growth when the other substance did not, but they also decreased several biomarkers for prostate cancer, reduced inflammatory markers, and increased the expression of a tumor suppressor gene. As Hippocrates once said, "Let food be thy medicine".
Trans Fats Impair Memory in Men
Trans fats are now recognized by nearly everyone has having a wide range of adverse health effects. Numerous studies have linked trans-fat consumption to heart disease, type-2 diabetes, increased inflammation, and cancer. At a recent conference held by the American Heart Association it was revealed that trans-fat consumption has now been linked to decreased memory in young and middle aged men. Researchers from the University of California-San Diego gave food questionnaires along with tests to assess memory skills to 1,000 healthy men with no history of heart or brain disease to determine the effect that trans-fats had on memory. After controlling for factors like age, ethnicity, and level of education it was determined that men who ate the most trans-fat performed noticeably worse on the memory examination. This is the first such study to link trans-fats to cognitive impairment, but the previously known ability of trans-fats to increase inflammation, which in turn increases oxidation, would seem to explain the connection.
Fiber Supplement May Promote Weight Loss
Previous studies have linked soluble corn fiber (SCF) to increasing the amount of good bacteria present in the small and large intestine during digestion. Now, a new study conducted by researchers at the University of Illinois has found that the shift in gut bacteria from SCF and another dietary fiber commonly found in food products known as polydextrose may have the ability to significantly impact weight loss. Researchers found that consuming diets high dietary fibers such as SCF and polydextrose caused an increase in substances identified as bacteroidetes, while reducing levels of harmful bacteria known as Firmicutes. While Bacteroidetes are said to be present in greater amounts in lean people, firmicutes are said to have a greater presence in obese individuals. And although they don't exactly understand the why bacteroidetes and firmicutes are a determining factor in body composition, a connection exists none-the-less. By shifting the gut bacteria from harmful, disease promoting bacteria it healthy, weight loss inducing bacteria, researchers believe they can find a way to use this information to develop a form of treatment or management for weight loss.
Calorie Restriction Impacts Gene Expression
The debate about whether prolonged calorie restriction or fasting is optimal for bodybuilding is marginally debatable, but the impact of caloric restriction on general health is another story. Numerous studies have delivered various form of evidence to support the benefits that fasting is in fact capable of producing unique physical health benefits. Now neuroscientists at NYU - Langhorne are reporting that calorie restriction appears to have an anti-aging effect in mice. When scientists feed female mice food pellets that contained 30% less calories they found that it changed the expression of nearly 900 genes associated with aging and memory in the brain. Researchers are quick to note that the results do not point to calorie restriction being a veritable fountain of youth, but it does open doors and raise questions about the impact of our diets on our genes.
Twenty Minutes Is All It Takes
It isn't exactly a well-guarded secret that exercise is good for us. Thousands of studies have identified a wide range of benefits stemming from the obvious physical benefits, to lesser known benefits such as reducing the risk of brain disease or helping to eliminate depression by boosting serotonin levels. However, what type of exercise, and exactly how much of it we need seems to anything but a general consensus amongst experts. However, a new study published in Scientific American is reporting that twenty minutes daily of any type of exercise is all it takes to to fire up our metabolic machinery. Researchers determined that something as innocuous as a brisk walk activates areas in the brain known as white matter which are responsible for connecting neuronal pathways on opposite sides of the brain.
