I don't think I'm alone when it comes to wanting to age gracefully. As I age, I'm worried that when I retire, I may not be as mentally and physically fit to enjoy retirement. That's one reason I'm drawn to natural health and wanting to make sure I am providing my body with a rich diet full of all the nutrition elements it needs to stay healthy.
It's another reason why I spend a lot of time reading the latest research on how to stay healthy.
This morning I can across this article in Inverse named LIFE EXTENSION: 5 PROMISING BREAKTHROUGHS THAT COULD BE GAME-CHANGERS.
I'm going to highlight some of the main points in the article and provide a link for you to read the full article on your own and make your own judgements.
5. THE RELATIONSHIP OF NUTRITION AND AGING"There’s plenty of evidence for the benefits of doing the boring stuff, such as eating right. A study of large groups of ordinary people shows that keeping the weight off, not smoking, restricting alcohol to moderate amounts, and eating at least five servings of fruit and vegetable a day can increase your life expectancy by seven to 14 years compared with someone who smokes, drinks too much and is overweight.""Cutting down calories even more — by about a third, so-called dietary restriction — improves health and extends life in mice and monkeys, as long as they eat the right stuff, though that’s a tough ask for people constantly exposed to food temptation. The less extreme versions of time-restricted or intermittent fasting — only eating during an eight-hour window each day, or fasting for two days every week — are thought to reduce the risk of middle-aged people getting age-related diseases."
None of this should come as a surprise too any of us who have been following nutrition news. I love good food - so keeping my calories count low is hard. Keeping it balanced is also a struggle.
4. BENEFITS OF EXERCISE ON AGING"You can’t outrun a bad diet, but that doesn’t mean that exercise does not do good things. Globally, inactivity directly causes roughly 10% of all premature deaths from chronic diseases, such as coronary heart disease, type 2 diabetes, and various cancers. If everyone on Earth got enough exercise tomorrow, the effect would probably be to increase healthy human life expectancy by almost a year.But how much exercise is optimal? Very high levels are actually bad for you, not simply in terms of torn muscles or sprained ligaments. It can suppress the immune system and increase the risk of upper respiratory illness. Just over 30 minutes a day of moderate to vigorous physical activity is enough for most people. Not only does that make you stronger and fitter, but it has also been shown to reduce harmful inflammation and even improve mood."
Another non-shocker - we all can probably agree to this without much dissection. Yet to stay active for many of us takes mindful effort. I have a hard time with most forms of exercise - some just bore me to death. You can't get me to jog or get on a treadmill. Yet I will chase that little yellow ball all day doing on a tennis court. I encourage you to find an activity that you can enjoyably embrace multiple times a week. If that doesn't exist - find something that you don't hate. Believe me, your body and health will thank you for years to come.
3. BOOSTING THE IMMUNE SYSTEM"However fit you are and well you eat, your immune system will, unfortunately, get less effective as you get older. Poor responses to vaccination and an inability to fight infection are consequences of this “immunosenescence”. It all starts to go downhill in early adulthood when the thymus — a bowtie-shaped organ in your throat — starts to wither.That sounds bad, but it’s even more alarming when you realize that the thymus is where immune agents called T cells learn to fight infections. Closing such a major education center for T cells means that they can’t learn to recognize new infections or fight off cancer effectively in older people.You can help — a bit — by making sure you have enough key vitamins, especially A and D. A promising area of research is looking at signals that the body sends to help make more immune cells, particularly a molecule called IL-7. We may soon be able to produce drugs that contain this molecule, potentially boosting the immune system in older people.Another approach is to use the food supplement spermidine to trigger immune cells to clear out their internal garbage, such as damaged proteins, which improves the elderly immune system so much that it’s now being tested as a way of getting better responses to COVID vaccines in older people."
Now we start getting into some new territory. Most people never ask what their Thymus and its function - much less how to keep it healthy. They point out that adequate amounts of Vitamin A and D are important. They also talk about how a molecule named IL-7 which may help boost the immune system in older people. We'll have to watch for more developments with IL-7 that in the research and news reports.
To many of us here, the supplement spermidine to "clear their internal garbage" is new. Very interesting. At this time we do not have any Spermidine products to recommend. Yet, we'll keep an eye on them.
2. CELL REJUVINATION"Senescence is a toxic state that cells enter into as we get older, wreaking havoc across the body and generating chronic low-grade inflammation and disease — essentially causing biological aging. In 2009, scientists showed that middle-aged mice lived longer and stayed healthier if they were given small amounts of a drug called rapamycin, which inhibits a key protein called mTOR that helps regulate cells’ response to nutrients, stress, hormones, and damage.In the lab, drugs like rapamycin (called mTOR inhibitors) make senescent (aged) human cells look and behave like their younger selves. Though it’s too early to prescribe these drugs for general use, a new clinical trial has just been set up to test whether low-dose rapamycin can really slow down aging in people."Discovered in the soil of Easter Island, Chile, rapamycin carries with it significant mystique and [has been hailed] in the popular press as a possible “elixir of youth”. It can even improve the memory of mice with dementia-like diseases.But all drugs come with pros and cons — and as too much rapamycin suppresses the immune system, many doctors are averse to even considering it to stave off age-related diseases. However, the dose is critical and newer drugs such as RTB101 that work in a similar way to rapamycin support the immune system in older people, and can even reduce SARS-CoV-2 infection rates and severity.

1. GETTING RID OF SENESCENT CELLS IN YOUR BODYCompletely getting rid of senescent cells is another promising way forward. A growing number of lab studies in mice using drugs to kill senescent cells — so-called “senolytics” — show overall improvements in health, and as the mice aren’t dying of disease, they end up living longer too.Removing senescent cells also helps people. In a small clinical trial, people with severe lung fibrosis reported better overall function, including how far and fast they could walk, after they had been treated with senolytic drugs. But this is only the tip of the iceberg. Diabetes and obesity, as well as infection with some bacteria and viruses, can lead to more senescent cells forming. Senescent cells also make the lungs more susceptible to SARS-CoV-2 infection, which makes more cells become senescent. Importantly, getting rid of senescent cells in old mice helps them to survive such infections.Aging and infection are two-way streets. Older people get more infectious diseases as their immune systems start to run out of steam, while infection drives faster aging through senescence. Since aging and senescence are inextricably linked with both chronic and infectious diseases in older people, treating senescence is likely to improve health across the board.
We may see some of these soon as clinical trials of these new treatments are looking pretty promising!
I hope you found these as fascinating as I did. I always find it enlightening to click the links and read more of the supporting information.
