Conventional wisdom at the time held that the more animals were fed, the better they’d fare. But McKay noticed something different: Long after the well-fed rats began to show signs of aging, those on a nutrient-dense but super-low-calorie diet retained a silky sheen to their fur, remained alert and agile and lacked the age-related health problems of their more gluttonous peers. In the end, the calorie-restricted mice also lived about 300 days longer — nearly a third of a lifetime in rat years.
Fast forward to 2020, and studies in everything from fruit flies and worms to monkeys and people have confirmed that sharply restricting calories (by 20-40 percent) while maintaining essential nutrients can fend off age-related diseases and, in some cases, extend lifespan. The problem: People like to eat, so almost no one is willing to do it. And it can be dangerous. Continue reading →
How many times do we have to say it? Eat less; move more; live longer. Here, it is supported by a new study presented at the Association of Academic Physiatrists Annual Meeting in Orlando.
Good exercise habits formed in adolescence correlate positively with exercise habits in adults, and adults with good exercise habits have better physical performance and appropriate body-mass index scores for their age, according to the study.
Regular exercise habits can lead to better physical fitness and mental health in people of all ages. However, research shows that people in the United States and Canada tend to exercise less as their age increases, and the most significant drop-offs in exercise habits take place during the teenage and early adult years. For this retrospective study, researchers in Taiwan wanted to know if exercise habits formed in adolescence could affect physical fitness in later adulthood, and to assess the relationship between adolescent and adult exercise habits and its influence on later physical fitness.

As a senior citizen who has had family members suffer from dementia and Alzheimer’s Disease, I want to know everything I can about aging and cognition, so this study from Florida Atlantic University piqued my interest.
The neighborhood environment may positively or negatively influence one’s ability to maintain cognitive function with age. Since older adults spend less time outside, the neighborhood environment increases in importance with age. Studies suggest physical aspects of the neighborhood such as the availability of sidewalks and parks, and more social and walking destinations, may be associated with better cognitive functioning. Beneficial neighborhood environments can provide spaces for exercise, mental stimulation, socializing and reducing stress. To date, few studies have examined how the neighborhood’s physical environment relates to cognition in older adults. Continue reading →
Life expectancy — the average number of years a newborn can expect to live — increased in the U.S. by almost 10 years between 1959 and 2016, from 69.9 years to 78.9 years. However, it declined for three consecutive years after 2014, driven largely by a higher mortality rate in middle-aged people of all racial groups.
In the NIA-supported study, researchers at Virginia Commonwealth University analyzed data from the National Center for Health Statistics, the U.S. Mortality Database, and CDC Wonder. They found that from 1999 to 2010, the number of deaths per 100,000 people decreased for all age groups. This decline is attributable to reduced death rates from several specific causes, including heart attacks, motor vehicle injuries, HIV infection and cancer.
Older adults who move more than average, either in the form of daily exercise or just routine physical activity such as housework, may maintain more of their memory and thinking skills than people who are less active than average, even if they have brain lesions or bio-markers linked to dementia, according to a study by Rush University Medical Center.
Women who can exercise vigorously are at significantly lower risk of dying from heart disease, cancer and other causes. The research was presented 7 December at EuroEcho 2019, a scientific congress of the European Society of Cardiology (ESC).
Study author Dr Jesús Peteiro, of University Hospital A Coruña, Spain advised women: “Exercise as much as you can. Fitness protects against death from any cause.”
Exercise is good for health and longevity, but information on women is scarce. Women generally live longer than men, so dedicated studies are needed. This study examined exercise capacity and heart function during exercise in women and their links with survival. The study included 4,714 adult women referred for treadmill exercise echocardiography because of known or suspected coronary artery disease. Continue reading →
I have to admit that I have been seeing items and ads about CoQ10 for years and never paid it much attention. I stumbled across this rundown in Medical News Today and was amazed at its functionality. I thought it would interest you.
CoQ10 is an antioxidant that exists in almost every cell of the human body. CoQ10 deficiency is associated with various medical conditions, such as heart disease, cancer, and Alzheimer’s disease.
Although the body naturally produces CoQ10, some people may benefit from taking supplements. Overall, CoQ10 supplements appear relatively safe and cause few side effects. Supplements are not regulated by the Food and Drug Administration (FDA) for purity or verified for labeling accuracy, so purchase only those products that have been tested by an independent lab.
People who are interested in trying CoQ10 supplements may want to consult a healthcare professional first. Experts do not recommend CoQ10 for people taking blood-thinning medications, insulin, or certain chemotherapy drugs.Continue reading →
Cognitive impairment without dementia (CIND), or mild cognitive impairment, is a condition that affects your memory and may put you at risk for Alzheimer’s disease and dementia. According to the U.S. National Library for Medicine, signs of mild cognitive impairment may include frequently losing things, forgetting to go to events and appointments, and having more trouble coming up with words than other people of your age.
My go-to exercise is biking. My dog comes along when the weather is willing. At 79, everything seems to be working …
Some experts believe that risk factors for heart disease also are risk factors for dementia and late-life cognitive decline and dementia. Recently, researchers examined two potential ways to slow the development of CIND based on what we know about preventing heart disease. They published the results of their study in the Journal of the American Geriatrics Society.Continue reading →
“It is important to say that it is never too late to begin exercising. The average participant in our study was around 60 years old at baseline, and improvement in cardio-respiratory fitness was strongly linked to lower dementia risk. Those who had poor fitness in the 1980s but improved it within the next decade could expect to live two years longer without dementia,” says Atefe Tari of the Cardiac Exercise Research Group (CERG) at the Norwegian University of Science and Technology (NTNU).
Colder temperatures, inclement weather, reductions in the amount of daylight, and the spread of cold and flu viruses can all have a significant impact on your winter well-being, making it more challenging for you to stay safe and healthy.
Here are four important tips and tricks to help you cope with the cold weather, care for your immune system, and stay active until spring arrives, from Western Connecticut Medical Group.
A little prevention in the fall can help everyone — and especially older adults — avoid serious wintertime accidents. Precautions include preventing falls by installing handrails and fixing uneven or steep stairs before the weather turns cold and icy.
Fall is also a great time to work on increasing your flexibility. Increasing your flexibility decreases your risk of falling. And if you do fall, flexibility helps to decrease the severity of the injury. Stretching several times a week can improve your flexibility. Traditional stretching, yoga, tai chi, or Pilates are all great ways to stay flexible. Continue reading →
A recent two-year clinical trial in Finland (the FINGER Study) reported that a combination of physical activity, nutritional guidance, cognitive training, social activities and management of heart health risk factors protected cognition in healthy older adults who were identified as being at increased risk of cognitive decline. Currently no pharmacological treatments are available that rival this effect.
“There is an urgent need to expand this work to test the generalizability, adaptability and sustainability of the FINGER study’s findings in geographically and culturally diverse populations in the U.S. and across the globe,” Morris said. “While there is no proven cure or prevention for dementia, current research shows that combining healthy lifestyle factors may counteract risk and help stave off dementia.” Continue reading →
Despite the evidence on risk factors for frailty, and the substantial progress that has been made in frailty awareness, the biological mechanisms underlying its development are still far from understood and translation from research to clinical practice remains a challenge, according to a new series on Frailty just published by The Lancet. Linda P. Fried, MD, MPH, dean of Columbia University Mailman School of Public Health and DeLamar Professor of Public Health Practice, and Professor of Epidemiology and Medicine, was part of an international group of experts who contributed to the series of papers which provide an up-to-date clinical overview on preventing, identifying and managing frailty as well as its global impact and burden. The series also offers evidence-based interventions for individuals with frailty. The findings are published online.
In the paper on Clinical Practice and Public Health, Fried, a renowned gerontologist and expert on aging, highlights two emerging lines of life course evidence on frailty. First, Fried and colleagues make the point that the risk of adverse outcomes can be predicted. Secondly, there is a clinical syndrome of frailty which is an outcome of biologic aging, although risk levels are substantially higher among those with certain diagnoses and comorbidities. She also notes that while great strides have been made in understanding frailty in the past two decades, many gaps in knowledge remain: no universal consensus exists on the definition of frailty or its assessment, and more robust, high-quality trials of strategies to prevent and manage frailty are needed.
Regular exercise is highly beneficial for all patients with cardiovascular disease regardless of age, report investigators in the Canadian Journal of Cardiology, published by Elsevier. Their results showed that the patients who benefited most from cardiac rehabilitation were those who started out with the greatest physical impairment. Continue reading →
I know that we are late in September and a lot of folks will be putting away their bikes ‘for the season.’ I ride year ’round here in Chicago and enjoy it. If you are one of those who haven’t ridden in a while and would like to take up a super form of exercise, I hope you will consider cycling. There are still a few good weeks left before the cold sets in. You can get started now.
The Harvard Health Publications has a nice positive blog post on starting cycling again presumably as a senior.
Heidi Godman, Executive Editor of the Harvard Health Letter, states that she loved riding as a kid, but now only rides occasionally.
“It’s fun, it’s socially oriented, and it gets you outside and exercising,” says Dr. Clare Safran-Norton, a physical therapist at Harvard-affiliated Brigham and Women’s Hospital. Plus, cycling is an aerobic activity, it’s easy on the joints, and it helps build muscle and bone. Continue reading →
When Toni Morrison died on Aug. 5, the world lost one of its most influential literary voices.
But Morrison wasn’t a literary wunderkind. “The Bluest Eye,” Morrison’s first novel, wasn’t published until she was 39. And her last, “God Help the Child,” appeared when she was 84. Morrison published four novels, four children’s books, many essays and other works of nonfiction after the age of 70.
Morrison isn’t unique in this regard. Numerous writers produce significant work well into their 70s, 80s and even their 90s. Herman Wouk, for example, was 97…
