Drink milk from grass-fed cows and have a healthier heart. This is because this milk has five times more unsaturated fat than that from grain-fed cows. You can even lose weight by drinking the milk. This is a call back to the past. Today most cows in the West are grain fed. People having high levels of unsaturated fat had a third less risk of getting a heart attack. Studies have found that a diet consisting of unsaturated fats reduced cancer cells and tumours.  Though meat from grain fed cows seems to have less fat, looks can be deceiving. There is a problem with the proposition from this research. In Australia and New Zealand milking cows are fed mainly on pasture. However, people in these countries are almost as fat as US citizens and high blood pressure is just as bad. As a person ages milk consumption decreases. Australians do eat a lot of take away food. And these food establishments foister coke on you. When you order tea or coffee you can almost hear a sigh from those servin

In the twentieth century Australia was dominant in swimming at international events. This was largely due to the high consumption of meat in the diet of Australians. As time went by other nations noticed this and their athletes ate more meat. Today, Even small island nations have access to reasonably priced beef, pork, lamb and poultry. Consequently, Australia's dominance has waned. Despite consuming a lot of meat, Australians did not die at a young age. Indeed, longevity was extended. New research points to an increase in heart disease, obesity, cancer and diabetes that do tend to shorten life. An example was given of Hawaii where these diseases are rapidly increasing. Red meat is seen as the major cause. This research has flaws. Higher red meat consumption cannot be directly linked to more "modern" maladies. It could be coincidence. No tests were done on the rising consumption of refined carbohydrates. The call for more vegetables in the diet will improve

Treatment for heart disease is advancing at a rapid pace. Soon, a tiny piece of artery will be removed from a patient and a new heart conduit will be formed. This is for minor problems in the heart, less that 5mm wide. Conduits are also being made from synthetic materials. Toleration of foreign substances is not a problems because it degrades quickly. They are used to go over the outside of a graft to stop bleeding. The synthetic conduits are made of a fine poly-(glycerol sebacate) net coated with polycaprolactone and the anticoagulant heparin. Mesh holes are too small for blood to pass through. Nothing of the implant remains after three months. A new structure of endogenous cells with M2 macrophages (which reduces inflammation) remains. Though tests have only been done on rats, use in humans will probably be just as successful. Large grafts using the material will be done to see if this is feasible. This will be a welcome advance in medicine. A graft made of the body's

Just as jerky handwriting can indicate that a person has cancer, so handwriting shows if a person has heart disease. Christina Strang gave a presentation at the International Graphonomics Society in Melbourne stating that she examined the handwriting of over 1,000 people in their 60s. The handwriting expert magnified handwriting looking for traits such as momentary stop-starts, location of dots, odd shaped 'o's, etc. She found that people with cardiac problems had more "resting dots" in the upper parts of 'a', 'e' and 'o's, vis-a-vis the control group. Doctors have dismissed the findings as being too general and unscientific, in much the same way as they did with similar research into Alzheimer's, Huntington's and Parkinson's diseases. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/http://adventure--austra

Superman or indeed cyberman could soon be with us. Artificial muscles that can hold thousands of times their own weight have been invented. The breakthrough has been made by a team from four nations: Australia, Canada, the US and Korea. Carbon nanotubes were first wound into yarn in Australia. This super strong material far exceeds the flexibility of other artificial muscles. This is not strictly new. It was done several years ago but now work is under way to apply the technology. The yarn is does not yet have enough mass to be used for arm or leg muscles. Ideally, better heart valves, pumps, and positioners could be developed. The yarn has an interesting property: it can be made into a helical structure that will rotate right or left. Applying an electric charge causes it to spin. This makes it easy to propel a tiny object along in the bloodstream for example. This new discovery could revolutionize medicine. http://www.adventure--australia.blogspot.com/ http://www.tysaustral

It seems people don't live on after their partner passes away. There is a higher risk of survivors getting a heart attack in the months after losing a husband or wife. It is believed to be due to the increased heart rate from the loss. If the living partner can get through the danger period the risk dissipates. This shows that people who lose partners need medical help and support from friends and relatives during the grieving process. Doctors should pay special attention to cardiac symptoms. Persistent stress and depression should also be monitored. The research involved people aged from 33 to 91, so this tendency affects spouses of any age. Subjects wore 24 hour monitors. Heart rate was closely observed. Periods of rapid heart beat occurred during the grieving period. Overall heart rate was also higher compared to people who had not had a loss. Depression was four time higher than the norm in subjects. This persisted for several years. http://www.adventure--australia.bl

A new method of treating asthma has been discovered. Formoterol is a synthetic form of catecholamine. This is a hormone that regulates metabolism, heart rate and breathing. It increases metabolism without raising the heart rate. Tests on animals have been promising. The drug is selective in that receptors in the lungs take on the catecholamine but receptors in the heart do not. A positive side effect it that it burns fat from the body. Eight men without asthma were given the medication for a week. Their energy metabolism increased by 10 per cent. Fat was burned off by 25 per cent. Protein only fell by 15 per cent. This means people can do more with leaner bodies. We may be entering a new age where obese people no longer have to suffer. They can have healthy bodies in the normal weight range. Tests on those with asthma will set the stage for this. Subjects will be closely monitored to determine long term effects. Hopefully they will all be beneficial. http://www.adventure-

Major medical advances are a long time coming. Development of a reliable blood sugar level monitoring method for type 1 diabetes is a case in point. It has been claimed as a revolutionary achievement. It consists of a monitor connected to an insulin pump. With all the money being poured into research this should have been done years ago. Heart surgery hasn't moved much further forward than the first transplant in South Africa decades ago. Stents are still the primary treatment. The number of heart transplant recipients remains very small indeed. Artificial hearts are still not safe enough for general use. Cancer shrinking techniques have been identified but they have not been perfected. DNA treatment is a long way down the track. Much hope had been raise over stem cell research. This has slowed right down. Surgical "tricks' have been done in one-off procedures. Getting them into general hospital systems is not happening though. Drug companies are pushing very expensive med
