People with poor dental hygiene are 21% more likely to develop dementia in later life, new research suggests. According to the study, recently published in the Journal of the American Geriatrics Society, poor oral health and tooth loss increased the risk of Alzheimer's disease. The study authors said their findings emphasize the importance of monitoring, as well as management of “periodontal health in the context of dementia prevention”. They added that because of this finding, dental professionals are in a great position to track and intervene should a patient's periodontal health begin to deteriorate. “Our mouth is full of bacteria (good and bad). We need these bacteria to live in equilibrium and when our dental hygiene is missing, the bad bacteria can overcome and install in our gums. There is evidence that bacteria can travel to the brain and participate with neurodegeneration that will ultimately decline our cognitive health,” she told Healthline. “Oral health is important for our overall quality of life. Taking care of our mouth is as important as taking care of our body. Our mouth is more exposed to the environment, and it is the entrance to our entire body,” she added. The research has spoken: Brush your teeth two to three times a day and visit a dentist twice a year as routine, or sooner if you notice a change in your dental health. *Image by Reto Gerber from Pixabay
The American Heart Association (AHA) has added sleep to its cardiovascular health checklist for the first time. Sleep now joins diet, exercise, tobacco use, weight, cholesterol, blood sugar levels and blood pressure on the association's list of factors people can modify to stay healthy. The AHA published its new checklist, called “Life’s Essential 8,” in the journal Circulation on June 29. The old checklist, created in 2010, was known as “Life’s Simple 7.” “Not only is sleep health related to the other things that play a role in heart health, it seems to also be directly related to cardiovascular health itself,” says Michael Grandner, PhD, the director of the sleep and health research program at the University of Arizona College of Medicine in Tucson, who helped compile the new AHA checklist. “Sleep is changeable, and studies show that you can improve aspects of heart health just by improving sleep,” Dr. Grandner says. People who get less than six hours of good quality sleep a night are at increased risk of obesity, high blood pressure and type 2 diabetes, as well as worse mental and cognitive health, Grandner says. Likewise, those who get more than nine hours of sleep a night are also less likely to be healthy and more likely to die prematurely, he added. *Image by Wokandapix from Pixabay
The Mediterranean diet, which features plenty of vegetables, fruits, herbs, nuts, beans and whole grains, has long been lauded for its heart health benefits. But now a new study shows that it could also improve brain function in elderly people, even when only eaten for a year. According to the research published in the BMJ, following a Mediterranean diet for just 12 months can inhibit production of inflammatory chemicals in elderly individuals that can lead to loss of cognitive function, as well as prevent the development of chronic diseases such as diabetes, cancer and atherosclerosis. For the study, 612 elderly people from France, Italy, the Netherlands, Poland and the United Kingdom has their gut microbiome analysed. Then, 323 of them were put on a special diet, based on Mediterranean principles, for one year, while the rest were asked to eat as they normally would. After 12 months, all of the study participants had their gut microbiome re-analysed. Those who had followed the Mediterranean diet saw beneficial changes to the microbiome in their digestive system. The rate at which bacterial diversity was lost slowed and the production of potentially harmful inflammatory markers was reduced. Furthermore, there was also a growth of beneficial bacteria linked to improved memory and brain function. So-called “keystone” species, critical for a stable “gut ecosystem”, were also boosted, helping to slow signs of frailty, such as walking speed and hand grip strength. “Our findings support the feasibility of changing the habitual diet to modulate the gut microbiota which in turn has the potential to promote healthier aging,” the study authors said.
