Testosterone protects against heart disease

Low testosterone levels are associated with a greater risk of heart attacks, diabetes, abdominal fat deposition and abnormal blood lipid levels. Cytokins, which cause inflammation in the arteries, are the latest suspected cause of heart disease. British researchers suggest testosterone suppresses cytokins and also boosts the immune system, thereby preventing heart disease. (J Endocrinol, 178: 373-380, 2003)

High Blood Pressure and Memory

High blood pressure is defined as a reading equal to or higher than 140/90 or taking medication for high blood pressure. According to research published in the Aug. 25 print issue of Neurology; high blood pressure is linked to memory problems in people over 45.

The study found that people with high diastolic blood pressure, which is the bottom number of a blood pressure reading, were more likely to have cognitive impairment, or problems with their memory and thinking skills, than people with normal diastolic readings.

For every 10 point increase in the reading, a person?s risk for cognitive problems was 7 percent higher. The results were adjusting for other factors that could affect cognitive abilities like age, smoking status, exercise level, education, diabetes, or high cholesterol.

The study involved nearly 20,000 people 45 and older across the country that participated in the Reasons for Geographic and Racial Differences in Stroke Study and had never had a stroke or mini-stroke. A total of 1,505 of the participants, or 7.6 percent, had cognitive problems, and 9,844, or 49.6 percent, were taking medication for high blood pressure.

“It’s possible that by preventing or treating high blood pressure, we could potentially prevent cognitive impairment, which can be a precursor to dementia,” said Dr. Georgios Tsivgoulis of the University of Alabama at Birmingham, one of the study authors.

Creatine, the oldest health care in the world, more Vitamin D, 4 things for your health

I this installment of Did you know… I cover an array of topics beginning with the following:

Did you know…

…creatine is perhaps the most researched supplement on the planet? Yet new data on the benefits of supplementing with this incredible substance is still mounting. Canadian researchers compared the changes in insulin-like growth factor-1 (IGF-1) amounts in two groups of subjects. All the subjects performed at least 30 minutes of structured physical activity three to five times per week for eight weeks. The subjects were randomly assigned to one of two groups: one supplementing with creatine, the other, an isocaloric placeo. Muscle biopsies were taken before and after the training period and analyzed for IGF-1 content. The creatine group had a 24% higher level of IGF-1. The creatine group also had a 23% higher increase in type II muscle fibers. These findings were independent of dietary guidelines. (Int J Sport Nutr Exerc Metab, 2008; 18(4))

What does this mean for the average Joe? It means if you supplement with creatine, you?ll not only get the well known ?volumizing? effect, but more muscle fibers.
