A Spoonful Of THIS In Your Daily Meals Can Lower Your Risk Of Dementia

(Credit-Canva)

Affecting millions of people throughout the globe, dementia is the seventh leading cause of death. There are many different variations of the condition, Alzheimer’s being the most common. In 2021, according to the World Health Organization, 57 million people were affected worldwide. 

When it comes to what <span>factors affect the risk of dementia</span>, your dietary intake is first in line to change. What you eat can increase or decrease the chance of you getting dementia. Researchers have found that something as simple as adding a spoonful of olive oil to your meals each day could have a big impact on your health, potentially lowering your chances of dying from dementia. 

Research suggests that this common cooking oil might have protective properties for the brain, in addition to its well-known benefits for the heart, making it a potentially life-saving habit to incorporate into your daily routine. 

<h2>How Dietary Habits Directly Impact Dementia Deaths?</h2>

Published in the JAMA Network Open by the Nutrition, Obesity, and Exercise 2024, this study specifically examined how individual foods within that diet relate to death rates associated with dementia. The researchers looked at the eating habits of a large group of adults and tracking how many of them eventually died from dementia. This long-term study allowed them to see if there were any connections between specific foods people ate regularly and their risk of dying from this brain condition. While past studies hinted that the Mediterranean diet might be good for the brain, this research specifically focused on how individual foods within that diet, like olive oil, were linked to dementia-related deaths. 

<h2>Long Term Implications of Olive Oil Intake </h2>

A dedicated team of researchers from a well-known health school in the United States followed the diets of more than 92,000 adults for nearly 30 years. All of these people reported eating at least a small amount of olive oil, about half a tablespoon, every day as part of their regular meals. By following such a large group over a long period, the researchers were able to gather a lot of information about the potential long-term effects of olive oil consumption on their health, particularly in relation to dementia. 

The results of this long-term study were quite striking. They found that the people who regularly made olive oil a part of their daily diet had a significantly lower chance – about 28% lower – of dying from dementia compared to those who didn't use olive oil often or at all. This suggests that consistently including even a small amount of this oil in your meals could offer a considerable level of protection against this devastating brain condition.

<h2>Replacing Unhealthy Fats with Olive Oil </h2>

Experts pointed out that their findings support the advice to use vegetable oils like olive oil in our diets. She suggested that this recommendation might be important not only for keeping our hearts healthy but also for potentially keeping our brains healthy as we age. She also noted that choosing olive oil, which is a natural product, instead of less healthy fats like margarine and the mayonnaise you buy in stores, could be a safe way to reduce the risk of dying from dementia. 

While the study found a clear link between eating olive oil and a lower risk of dementia death, experts are still looking to understand the disease more. They have identified several things that can make a person more likely to develop the condition. While some of these risk factors, like how old you are and your genes, are things you can't change, others are related to your lifestyle choices. 

Health experts recommend several lifestyle changes that may help reduce the risk of developing dementia. These include eating a well-balanced diet rich in fruits, vegetables, and healthy fats like olive oil, maintaining a healthy body weight, engaging in regular physical activity, limiting alcohol consumption, quitting smoking, keeping your blood pressure at a healthy level, and staying socially active and connected with others

A experimental vaccine for acne has officially entered human clinical trials. The vaccine presents a new avenue of treating the underlying causes of acne, one of the most prevalent and chronic skin conditions that occur in an estimated 95% of individuals aged between 11 and 30. If it works, it may mark a paradigm shift away from long-term, side-effect-suffering therapies to a more sure, science-based immunological cure. 

Acne is more than just a teen annoyance, it's a condition involving inflammation of the skin that effects mental health, self-esteem, and quality of life. It forms when pores and follicles in the skin get blocked by extra oil, dead cells, and, in many cases, the presence of bacteria known as Cutibacterium acnes (C. acnes). The outcome: painful pimples, nodules, and cysts, usually found on the face, chest, and back. Developed by pharmaceutical giant Sanofi, the potential medical breakthrough has the potential to revolutionize treatment of acne globally. 

Hormonal fluctuations (particularly at puberty), genetics, stress, diet, and drugs are general precipitants. More recently, though, the involvement of skin-resident pathogens such as C. acnes has gained wider scientific attention, revealing new therapeutic opportunities not least, vaccines.

Sanofi's April 2024-initiated clinical trial is a Phase I/II trial to be conducted through 2027. It will assess both the safety and effectiveness of the <span>acne vaccine</span> in adults between the ages of 18–45 with moderate to severe facial acne.

The research will consist of about 400 participants who will be administered different levels of the vaccine — up to three shots throughout the study. There will be a control group that will get a placebo, which will enable researchers to compare and measure the actual effect of the vaccine.

While Sanofi has not issued full technical information, publicly available reports show the vaccine employs mRNA technology — a game-changing technique well known throughout the COVID-19 pandemic. Such a vaccine functions by teaching the body's immune system to attack particular proteins — in this instance, most likely those manufactured by C. acnes — to eliminate their acne-causing impact.

<h2>Why an Acne Vaccine Might Change Skin Therapies?</h2>

Treatment of current acne is symptom-oriented. The following are the measures used:

<ul><li>Topical and oral retinoids to enhance skin turnover</li><li>Antibiotics to decrease bacterial overgrowth</li><li>Hormonal therapy (for example, birth control pills) to moderate internal stimuli</li></ul>

Yet, such treatments are severely constrained. Retinoids are known to create such severe dryness and have been implicated in mood alteration, whereas long-term use of antibiotics leads to drug resistance — an increasingly mounting public health challenge. Hormonal treatment is not appropriate for all consumers and necessitates regular medical supervision.

An acne vaccine, however, presents the possibility of longer-lasting relief without daily treatment. It might decrease reliance on drugs, lower side effects, and possibly stop acne flare-ups from occurring at all by addressing underlying reasons — and not only the symptoms.

<h2>When Might the Acne Vaccine Arrive?</h2>

Despite the excitement, Sanofi’s vaccine is still in the early stages of development. Results from this Phase I/II trial are expected post-2027, and if they are promising, the vaccine would then move into larger-scale Phase III trials, which could take several more years.

Globally, historically, it can take a decade or more from the point of conception to the time when any new vaccine is being distributed worldwide.

In addition to demonstrating efficacy, scientists have to figure out how frequently the vaccine must be given, how long the immunity will last, and if it can be used preventatively in people who are genetically or hormonally predisposed to acne.

Encouragingly, Sanofi also hopes to start another Phase I trial in 2027 for those with less severe acne, further broadening the reach of the vaccine.

<h2>Are There Any Other Acne Vaccines Being Developed?</h2>

Sanofi is not the only one in the race. Scientists at the University of California, San Diego, are working on a vaccine that attacks a mutated form of an enzyme known as hyaluronidase, present in the acne-producing strains of C. acnes. The enzyme dissolves hyaluronic acid, a naturally occurring molecule in the skin that keeps it hydrated and intact. When disrupted, it initiates immune reactions that result in inflammation, the defining feature of acne.

However, these alternative vaccines are still in preclinical stages, placing Sanofi’s candidate at the forefront of global acne vaccine research.

While the acne vaccine remains a fantasy at this point, its promise is huge. It may revolutionize acne treatment in the same manner vaccines have altered the way infectious diseases are treated. For millions of people suffering from chronic acne and its mental price tag, the prospect of unblemished skin from one injection means more than medical progress — it means empowerment, self-esteem, and freedom. Here are some natural ways you can combat and manage your acne prone skin by checking your skin type and following the below steps:

1. Stay hydrated and drink 2–3 liters of water daily. Incorporate water-rich fruits and vegetables like watermelon, cucumber, and oranges. Herbal teas with ginger, lemon, or chamomile aid digestion and promote glowing skin.

2. Follow a balanced diet based on your Ayurvedic prakriti and elevated doshas. Include whole grains, dairy, seasonal fruits, and antioxidant-rich foods like tomatoes, broccoli, and papaya. Avoid fried, refined, and processed foods, as well as excessive sugar, salt, and red meat.

3. Regular exercise promotes blood circulation, detoxification, and skin nourishment. Activities like yoga, walking, or dancing improve oxygen flow, flushing out toxins and revitalizing the skin.

4. Maintain a consistent sleep schedule. Restful sleep stimulates growth hormones, promoting collagen and elastin production, which keeps skin firm and youthful.

As clinical trials continue, dermatologists and global public health officials will keep a keen eye on results. If this vaccine passes safety and efficacy standards, it may one day redefine the world of skincare as we know it.

According to the eye foundation, hydration helps us form tears, keep our eyes hydrated and free of infections, it also helps clearing toxins from the body as well as carry essential vitamins and minerals throughout our body. 

However, a recent report has revealed a significant problem in the UK, many people don't know how their diet affects the health of their eyes. the study highlighted the lack of understanding that people have about the vital role hydration, vitamins and minerals that we need to survive. It means that people might not be making the right food choices to keep their eyes healthy in the long run, potentially leading to vision problems later in life that could have been avoided with better nutritional knowledge. 

The study, called 'SEEING SENSE: The Nation's Eye Health Knowledge And The Impact Of Diet,' was put together by MacuShield, a company that makes supplements for eye health. The name of the report itself suggests that there's a need for more common sense and understanding when it comes to looking after our eyes through what we eat.

Some people get enticed by color of eyes. While it is true that eye color may interest some people, there exists an entire tribe who have a remarkably strange eye color. This is the Buton tribe of Indonesia who have sparkling blue eyes. 

This tribe is located in the southeast Sulawesi region of Indonesia. Ever since a photo taken by geologist and photographer Korchnoi Pasaribu went viral on social media, more and more people got interested to know how people can be born with natural sparkling blue eyes.

Upon researching, it has been revealed that this eye color exists due to a rare <span>genetic disorder</span> called Waardenburg Syndrome. This causes congenital hearing loss and pigmentation deficiencies, which can turn your eyes bright blue. It can also create a white forelock, or patches of light skin. Often times, you can have one blue eye, while your other eye is brown. 

As per the National Library of Medicine's published study, Waardenburg Syndrome is a group of genetic conditions caused by mutations in genes that disrupt the migration and division of neural crest cells. 

Waardenburg syndrome involves varying degrees of congenital sensorineural hearing loss along with pigmentation abnormalities. It is divided into four types, each with unique clinical features and genetic mutations. A family history of the condition is a key risk factor, as it follows autosomal dominant or, in some subtypes, autosomal recessive inheritance patterns.

Type I (WS1): Characterized by distinctive facial features, including dystopia canthorum (wide spacing between the inner corners of the eyes). It is caused by mutations in the PAX3 gene.

<strong>Type II (WS2): </strong>Similar to WS1 but without dystopia canthorum. It can be caused by mutations in different genes, such as MITF or SNAI2.

Type III (WS3): Also known as Klein-Waardenburg syndrome, this type includes the features of WS1 along with abnormalities of the arms and hands (upper limb malformations). It is also linked to PAX3 mutations.

<strong>Type IV (WS4): </strong>Known as Waardenburg-Hirschsprung disease, this form combines typical WS features with Hirschsprung disease—a condition affecting the large intestine due to missing nerve cells in the bowel wall. Mutations in genes like EDNRB, EDN3, or SOX10 are involved.

Waardenburg syndrome is diagnosed through clinical evaluation, supported by hearing tests and, when possible, molecular genetic analysis. Management involves early hearing rehabilitation, regular eye checkups, and cosmetic support for pigmentation changes. Prognosis varies with the type and severity, but with timely intervention, most individuals can expect normal development and life expectancy.

Most people diagnosed with this condition usually inherit it from one parent who passes a copy of mutated gene to their child during conception (autosomal dominant). 

However, if an entire tribe has the similar genetic disorder, the changes are endogamous marriages and inherited Waardenburg syndrome type II and type IV in an autosomal recessive pattern, which occurs when both parents pass a copy of the mutated gene to their child during conception.

Management involves early hearing rehabilitation, regular eye checkups, and cosmetic support for pigmentation changes. Prognosis varies with the type and severity, but with timely intervention, most individuals can expect normal development and life expectancy.Is It Hereditary?Most people diagnosed with this condition usually inherit it from one parent who passes a copy of mutated gene to their child during conception (autosomal dominant). However, if an entire tribe has the similar genetic disorder, the changes are endogamous marriages and inherited Waardenburg syndrome type II and type IV in an autosomal recessive pattern, which occurs when both parents pass a copy of the mutated gene to their child during conception.
