Taking this vitamin regularly can slow down ageing and improve longevity
Who wants to look old? Who doesn't want a longer life? Absolutely everyone!
In the quest for healthy aging, scientists are turning increasing attention to nutrients that do more than just support your basic body functions. What if I tell you there is a miracle vitamin that has shown impressive progress in slowing down the biological aging process?
According to new findings published recently from a major clinical trial in the
American Journal of Clinical Nutrition
, taking a daily dose of Vitamin D supplements could help slow down the cellular aging process by protecting telomeres.
This study went on for four years and studied over a thousand individuals (adults) and concluded that vitamin D3, also known as the sunshine vitamin, prevents the equivalent of nearly three years of aging compared to the placebo, suggesting evidence against this supplement counteracting natural biological aging at the cellular level.
The American Journal of Clinical Nutrition published a report in VITAL, a sub-study led by Mass General Brigham, which supports vitamin D supplements' potential in slowing biological aging.
Co-author JoAnn Manson, MD, highlighted VITAL's role in telomere protection and preservation.
What does it mean by countering natural biological age at the cellular level?
This process refers to slowing down or reversing the signs of aging by targeting the underlying cellular mechanisms in the body rather than just treating external symptoms such as wrinkles and fatigue. As we begin to age, our cells undergo changes such as telomere shortening, oxidative stress, and mitochondrial decline.

By focusing on these processes, researchers aim to delay the aging process not just at the surface but deep within. It is not just about appearing younger but actually about functioning like a younger, healthier person at the cellular level.
What are the properties of Vitamin D3, and why is it called the sunshine vitamin
Vitamin D3 is commonly known as cholecalciferol. A fat-soluble vitamin essential for various bodily functions. It helps to absorb calcium, which is crucial for maintaining healthy bones.
It is famously called the sunshine vitamin because the body naturally produces this when the skin is exposed to sunlight, especially UVB rays.

When our skin is exposed to sunlight, it synthesizes vitamin D3 from cholesterol. Since this is a natural process, it makes sunlight the primary and most efficient source of Vitamin D for most people. Vitamin D3 has been associated with slower cellular aging due to its role in reducing inflammation, supporting mitochondrial function, and preserving telomere length—all of which are key to aging and longevity.
Consuming vitamin D supports DNA health and repair.
Deficiency is more common than you think
Despite people knowing its importance, it still has a widespread deficiency. Particularly among older adults, the National Institute on Aging describes older adults as generally people aged 65 and above (definitions of older adulthood vary).
The World Health Organization has acknowledged that Vitamin D deficiency is a widespread and frequently underdiagnosed issue and a public health concern. This is highlighted in a joint publication by
the Lebanese Ministry of Public Health and WHO,
stating, 'Vitamin D deficiency is a public health problem that is widespread and frequently underdiagnosed."
The problem is exacerbated by the fact that vitamin D is not available in our daily food consumption, and as we age, the skin's ability to synthesize D3 from sunlight starts to diminish.
Natural resources and supplementation
While sunlight is the best source of Vitamin D, others include
Fatty fish
Fortified foods such as milk, orange juice, and cereals
Egg yolk
Mushrooms
While no single nutrient can stop the clock, maintaining adequate vitamin D3 levels may help slow down the ticking clock. Remember, nothing is a miracle; it is all about how consistently effort is applied and the right choices are made.

Mosquitoes may be attracted and hence, more likely to bite THIS blood type
We all have to deal with pesky mosquitoes, especially in warm weather. No matter how many repellents and creams we use, these little creatures somehow find a way to come and bite us, even hovering around our heads all the time! However, have you ever noticed that there are some people who are more likely to be bitten by mosquitoes than others? These people are the first ones to lather themselves up with sprays and lotions, and do not leave the house before covering themselves up fully. Research suggests that mosquitoes may be more attracted to certain blood types, making those individuals more likely to get bitten. Here's how blood type influences mosquito attraction and what other factors also play a role. Let's know more about blood types Blood types are categories based on the presence or absence of specific proteins called antigens on the surface of red blood cells. The four main blood types are: Type A: Has A antigens Type B: Has B antigens Type AB: Has both A and B antigens Type O: Has no A or B antigens These antigens can also be secreted in body fluids like saliva and sweat in some people, known as "secretors" of their blood type. Do mosquitoes prefer a blood type Multiple studies have shown that mosquitoes tend to prefer people with blood type O over other blood types. For example, a study found that mosquitoes landed on people with type O blood twice as often as on those with type A blood. People with type AB blood were bitten the least, and type B was somewhere in between. A 2004 study specifically looked at the mosquito species Aedes albopictus and found that mosquitoes landed significantly more on people with blood type O than on type A. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Dr Sarah Brewer: Take 1 Cup Before Bed, Watch Your Body Thin Down Full Nutrition Secrets Undo This was especially true for those who are secretors of their blood type antigens. Why is O blood type a mosquito favorite One reason might be related to the chemical signals mosquitoes detect on human skin. Blood type O individuals secrete a substance called the H antigen, which may be more attractive to mosquitoes than the A or B antigens present in other blood types. Mosquitoes use their sense of smell and other sensory organs to detect these antigens, which could explain their preference. However, scientists caution that blood type is just one part of the story. Mosquitoes do not rely on blood type alone to choose their victims. Other factors Besides blood type, several other factors influence how attractive a person is to mosquitoes: Body Odor: Mosquitoes are drawn to certain compounds on the skin like lactic acid and ammonia. The types and amounts of bacteria living on your skin also affect your smell, making some people more appealing to mosquitoes. Carbon Dioxide: Mosquitoes can sense carbon dioxide that people exhale. Those who breathe out more carbon dioxide, such as people who are exercising, pregnant, or have a higher metabolic rate, tend to attract more mosquitoes. Body Heat: Mosquitoes are attracted to warmth. People with higher body temperatures may get bitten more often. Clothing Color: Dark colors like black, red, and dark blue attract mosquitoes more than light colors. Alcohol Consumption: Drinking beer or alcohol may increase mosquito attraction, possibly by changing body odor or metabolism. One step to a healthier you—join Times Health+ Yoga and feel the change

'Next pandemic far from over': Delhi HC asks for Centre's report on sample collection policy
'Next pandemic far from over': Delhi HC asks for Centre's report on sample collection policy NEW DELHI: Observing that the "next Covid-19 pandemic" is far from over, Delhi High Court has called for a status report from the Centre on what decision has been taken regarding the policy for sample collection, sample collection centres and sample transport. On May 28, a single judge bench of Justice Anish Dayal said that the matter assumed urgency considering reports of Covid-19 being active in the community. The bench noted that there was no update provided by the Centre regarding the result of the meeting held on May 30, 2023. It said that, at first glance, the contempt petition may not subsist considering the decision to form sub-committees. "However, considering that the next Covid pandemic is far from over and, in fact, active amongst the community today, as per news reports, the vacuum, if any, of steps taken post the meeting of 30 May 2023, is a serious issue," the court said. The matter will now be heard on July 18. The court was hearing a contempt plea filed by a doctor, Rohit Jain, alleging non-compliance by the authorities of an order passed by a division bench on Jan 27, 2023. The bench had disposed of Jain's plea on the issue while directing central govt to treat it as a representation and decide the same within 12 weeks by way of a reasoned order. According to Jain, despite the said orders, no guidelines were framed by the Centre with respect to the establishment of minimum standards for sample collection, sample collection centres and sample transport. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch vàng CFDs với sàn môi giới tin cậy IC Markets Tìm hiểu thêm Undo A meeting was held under the chairmanship of the additional director general of health services on May 30, 2023, where Jain was also invited to be present, based on the judicial orders. A decision was taken to constitute four sub-committees of experts in pathology, biochemistry, haematology and microbiology. The members of the committee were to define standard operating procedure for sample collection, sample collection centres and the sample transport policy. The guidelines were to include storage standards as well, the order notes. There were other actions which were decided to be taken in the said meeting, the court noted. The court observed that though it is sanguine that steps were taken and protocols were in place, it is imperative for the authorities to place the same on record.

Ahmedabad teen with cardiac issues 2nd to die of Covid in two days
Image used is for representational purposes only AHMEDABAD: The city on Sunday recorded the second death of a Covid-19 positive patient within two days. An 18-year-old girl from Vinzol area, who was admitted to LG Hospital with complaints of respiratory illness, succumbed to the viral infection Sunday night. Meanwhile, Gujarat added 95 fresh Covid cases taking the total active cases to 397, according to data released by the state health department Monday. Of these, 22 are hospitalized Dr Bhavin Solanki, medical officer of Ahmedabad Municipal Corporation, confirmed the death and said that known comorbidities for the patient included cardiac issues. "We received details from the hospital. There were reports of the girl being pregnant, but we are yet to verify it. She had a hospitalisation period of about two days," he told TOI. On Saturday, a 47-year-old woman from Danilimda, who was also admitted to LG Hospital, died due to health complications. In both cases, the authorities were silent on the cause of death. Experts, however, pointed at breathlessness and pulmonary infections as possible reasons for their demise. It is notable that in this wave, more than 50% of the patients are below 50 years of age. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Over 40 and Struggling With Belly Fat? Try 1 Teaspoon Daily (See Results Fast!) getfittoday Undo In Ahmedabad, out of 140-odd cases, about 10% are below one year of age, said sources. The youngest patient was two days old, whereas another patient at Civil Hospital was eight months old, according to hospital data. It is notable that Gujarat ranks fourth in the country in terms of active cases at 338. Kerala leads the tally with 1,435 active cases as at 8 am on Monday, followed by 506 in Maharashtra, and 483 in Delhi. Some other states with high cases include West Bengal at 331 and Karnataka at 253. In 24 hours ending 8 am, Gujarat added 18 new cases, according to Covid dashboard of the Ministry of Health and Family Welfare (MoHFW). Since January 1, India has recorded 32 deaths related to Covid, according to the dashboard, including four in the past 24 hours. TOI had reported earlier that the prevalent strains in Covid positive cases in Gujarat include LF.7 in four cases, and LF.7.9 and XFG each have three cases each out of 15 positive samples analysed in the state till last week. Experts said that all are Omicron variants and so far, there has been no major threat associated with the variants with low morbidity and mortality across India. "The double season this month has caused a rise in flu-like symptoms among patients. The symptoms of Covid are no different. Covid is endemic now, and there is no need to be alarmed with rise or fall in the number of cases reported. Majority of the patients do not show any major effect due to acquired immunity," said a city-based physician.
