According to a new report by the World Health Organisation, Bacon is BAD! More accurately, the study says that processed meats like hot dogs, sausages and bacon can cause colon cancer and red meat is also a likely cause of the disease, World Health Organisation experts say, in a potentially heavy blow for the global meat industry.
The analysis of 800 studies from around the world by the International Agency for Research on Cancer – IARC – found “sufficient evidence in humans that the consumption of processed meat causes colorectal cancer”.
“Each 50-gram portion of processed meat eaten daily increases the risk of colorectal cancer by 18 per cent,” it said in a statement.
The category includes meat that has been salted, cured, fermented or smoked, hot dogs, sausages, corned beef, dried meat like beef jerky or South African biltong, canned meat or meat-based sauces.
The finding supports “recommendations to limit intake of meat” particularly in processed forms, the IARC said :: Read the full article »»»»
25 years ago, in 1990, maternal and child malnutrition, unsafe drinking water and sanitation were the leading risks for death. Today, unsurprisingly, poor diet has overtaken third world problems as the biggest contributor to early death around the world.
According to new analysis from the leading authority on global disease diet is the second highest (clearly aside from age) killer.
Smoking cigarettes still carries the highest risk factor of premature death, followed by high blood pressure and obesity.
However, the Institute of Health Metrics and Evaluation – IMHE – says that a combination of dietary factors, from eating too few fruits and vegetables, nuts, and whole grains to too much sodium and cholesterol, is taking a toll on health across the globe.
The IMHE’s study found that the largest contributor to early death globally is high blood pressure, in which age and family history partly play a roll, but so do obesity, smoking, excessive salt consumption, lack of exercise, and drinking large amounts of alcohol.
Noteworthy, alcohol is also one of the top 10 risk factors associated with the highest number of deaths for both men and women.
The study looked at 14 dietary risk factors. Cumulatively, unhealthy eating, including diets low in fruit, whole grains, and vegetables, and diets high in red meat and sugar-sweetened beverages contributed to more deaths than any other factor, causing ischemic heart disease, stroke and diabetes :: Read the full article »»»»
The researchers have thrown cold water on the use of ice baths to soothe the overworked muscles of athletes.
According to conventional thinking, ice baths reduce inflammation and damage. however a joint study by the University of Queensland and Queensland University of Technology has found an active warm down is more effective in building muscle mass and strength.
The University of Queensland’s School of Human Movement’s Dr Llion Roberts tracked the progress of 21 men who did strength training two days a week for three months.
Half of them did an active warm down and the rest had a 10 minute ice bath at 10 degrees :: Read the full article »»»»
The bionic heart was designed by Brisbane engineer Dr Daniel Timms in 2001 while he was studying at the Queensland University of Technology.
It contains a spinning disc with small blades on each side that pump blood around the body and lungs, without a traditional pulse.
The bionic heart can last at least 10 years and could help bridge the gap between patients requiring heart transplants and the number of donor hearts available.
The team, made up of Queensland and international researchers, said the device was a significant advance on other designs that were large, prone to wear, or could only pump on the left or right side.
It is expected to be ready for human trials within three years :: Read the full article »»»»
