Too Much Sugar Can Cau
se Heart Failure
A study published by The Journal of the American Heart Association has found that consuming just one molecule of a glucose metabolite known as glucose phosphate 6 (GP6) can lead to improper heart function. People consuming diets high in sugars and refined carbohydrates are most likely to build up high levels of GP6, leading to cardiac distress. The findings were announced at the American Heart Association’s 50th Annual Conference on Cardiovascular Disease Epidemiology and Prevention, and provide hope that the message about the dangers of a high carbohydrate diet may finally be trickling down to the general public.

Men with Muscle Are 40% Less Likely To Die From Cancer
A study published in the journal Cancer Epidemiology, Biomarkers and Prevention has shown that men with stronger muscles from weight training are 40% less likely to die from cancer than those who do not train. The study was conducted by an international team of researchers and was comprised of 8,677 men who were monitored from 1980-2003. Each participant underwent regular monitoring which included medical checkups and tests of their muscular strength. The results showed that men who trained with weights and had the highest levels of strength were up to 40% less likely to die from tumors, and even those who had what was considered excess abdominal fat still seemed to receive the same benefit from regular weight training.
Ibuprofen or Acetaminophen Increase Muscle Strength in Resistance Training
A study conducted by Ball State University has found that using ibuprofen or acetaminophen at recommended dosages has the ability to increase muscle strength and muscle mass. In the study researchers split thirty-six men and wom
en into groups that received acetaminophen, ibuprofen, or a placebo. Participants were required to undergo three months of weight training conducted in a human performance laboratory to monitor training intensity. At the conclusion of the study the groups that received ibuprofen and acetaminophen showed enhanced protein synthesis according to intramuscular changes recorded by Magnetic Resonance Imaging (MRI).

Scientists Identify Four Genes that Influence LDL Cholesterol
Researchers from Texas Biomedic
al Research Institute have identified four genes that they believe have the ability influence levels of LDL cholesterol in the blood. The study, which was published in the Journal of Lipid Research, was conducted on a group of 1,500 baboons that were divided and fed high fat, high cholesterol diets for seven weeks. Scientists then used gene technology and genetic sequencing to identify the four genes that were expressed in the groups that contained high and low levels of LDL cholesterol. The four genes have been identified as TENC1, ERBB3, ACVR1B, and DGKA, all of which are genes that are also known to be associated with the cancer as well. Researchers are optimistic that by identifying the genes responsible for heart disease they will one day be able to design individual treatments at the genetic level.

Good Night’s Sleep Protects Heart
According to a large study conducted by researchers in the Netherlands, getting a good night’s sleep can decrease the risk of cardiac disease in already healthy individuals. Researchers tracked over 14,00
0 men and women for over a decade, during which time they found that those who exercised regularly, did not smoke, drank alcohol in moderation, and ate a healthy diet were 57% less likely to acquire cardiac disease. Those who did develop some form of cardiovascular disease were 67% less likely to die from related complications. In addition to the previously mentioned lifestyle factors, researchers found that individuals who were able to regularly sleep at least seven hours per night had amplified results that showed a 65% lower risk of acquiring cardiac disease and an astounding 83% reduction in death from cardiovascular disease.
