Approximately thirty years ago, scientists connected the length of telomeres to healthy aging and life-span.
Telomeres are cap-like structures found at the end of all your chromosomes.
As you age, your cells replicate many times over. Every time they replicate, the telomeres shorten. Scientists stated that this is a significant factor of aging and eventual death.
The telomeres shorten until they can’t anymore, causing cell death.
Finding ways to lengthen the telomeres can increase longevity and life- span.
A recent study published on January 1, 2021, suggests that polyunsaturated fatty acids, particularly arachidonic acid (an omega-6 fatty acid), may be a way to lengthen the telomeres.
A separate study published on April 23, 2020, research was done on 1,649 people whose telomere length, vitamin D levels, and other tests were measured.
The researchers discovered that the study participants with a vitamin D deficiency had a significant reduction in telomere length.
Numerous studies show a connection between vitamin D and telomere length. Increased vitamin D levels can lengthen them and provide you with longer and healthier aging.
How To Get Arachidonic Acid From Yor Diet?
Liver For Increased Life-Span
Liver is one of the best sources of arachidonic acid. It contains 350mg per 100 grams of cooked edible liver. If you do not eat meat, you can try egg yolks at 280 mg per 100 grams of yolk.
Arachidonic acid has gotten a bad reputation for being harmful. However, this omega-6 fatty acid has many potential health benefits.
Arachidonic acid has the following benefits: (Source)
- helps the brain
- helps skeletal muscles
- can stop the beginning of tumor formations
- for neurological disorders
- for better exercise
- cognitive function
- helps the immune system
The American Heart Association also confirms that arachidonic acid and other omega-6 fatty acids are beneficial for health.
The precaution is to eat plenty of omega-3 fatty acids together with omega 6’s (the correct ratio). They work in synergy. The proper balance should be “omega-6 to omega-3 (4:1 ratio or 2.5:1)“.
Natural Vitamin D From Sunlight
You can get plenty of vitamin D from the sun.
Vitamin D is beneficial for: (Source)
- heart disease
- Type 2 diabetes
- cognitive impairment
- Parkinson’s disease
- autoimmune diseases
- fractures and falls and much more
As shown, vitamin D is essential for health, but now there is evidence that it is cellularly connected to longevity and how long you may live.
A deficiency in this vitamin (actually a hormone) may take healthy years from your life.
Factors That Affect How Much Vitamin D You Get From The Sun
Ordinarily, the recommended dosage of vitamin D is somewhere between 400 and 100 International Units (IUs) per day.
You can get this amount from the sun. However, several factors are involved when it comes to getting enough vitamin D from the sun, such as:
- skin type
- your age
Scientists have determined that people fall under six different skin types. The measurement is called the “Fitzpatrick Scale.“
The Fitzpatrick scale contains Type 1 Skin (always burns, never tans, pale-skinned) to Type 6 Skin (never burns – dark pigmented skin color)
The darker you are, the more sunlight exposure you will need to get enough vitamin D to meet the daily requirement.
It has been shown that people over 50 years old do not synthesize vitamin D from the sun as much as a younger person.
It is a significant reason why the elderly are deficient in this vitamin. The elderly need to get more exposure from the sun to get vitamin D’s daily requirement.
The farther you live from the equator, the lesser vitamin D your skin will be able to synthesize from the sun.
The sun’s rays are weaker. The location factor should be taken into account also.
The season of the year is evident. Your skin is covered with more clothing than in the summer. So, the sun’s rays do not contact your skin.
Also, the sun’s rays are weaker during the winter season, making it more challenging to get enough vitamin D.
In the end, you can always take vitamin D in a supplemental form if desired.
Vitamin D and polyunsaturated fatty acids, especially arachidonic acid, have been linked to the length of your telomeres.
Reduced levels of both show that your telomeres become shorter. Shorter telomeres affect life-span and healthy aging.
Liver is an excellent source of arachidonic acids, and the sunlight is an excellent natural source of vitamin D.
Adding a little more of both to your diet and life may extend your life-span, longevity, and health.
