Warning! Diet sodas and soft drinks may triple the risk of stroke and dementia
Stroke
has raised concerns about the health impacts of diet sodas and soft drinks. Researchers found that individuals who consume one or more artificially sweetened beverages daily may face nearly three times the risk of ischemic stroke and Alzheimer's dementia compared to those who rarely drink these beverages.
The study tracked over 2,800 adults aged 45 and older for ten years, highlighting a strong association between diet soda consumption and serious neurological conditions. While the findings do not establish direct causation, they suggest a need for caution and further research into the long-term effects of artificial sweeteners.
The study and its findings on diet sodas and cold drinks
The research involved participants reporting their beverage consumption habits, including diet sodas and other cold drinks, at several intervals and monitoring their health outcomes over a decade.
Those who drank at least one artificially sweetened cold drink daily showed hazard ratios close to 3.0 for both ischemic stroke and Alzheimer's dementia, indicating a significantly increased risk. The study controlled for various factors such as age, gender, diet quality, and physical activity, strengthening the reliability of the association.
Although the exact types of artificial sweeteners were not specified, the results add to growing concerns over the safety of these common additives.
How diet sodas affect the body
Diet sodas, despite containing little to no sugar, often rely on artificial sweeteners that can disrupt the body's metabolic processes. These sweeteners may affect gut bacteria, influence glucose regulation, and alter brain chemistry, potentially increasing vulnerability to neurological diseases. Furthermore, the caffeine and phosphoric acid in sodas contribute to elevated blood pressure and mineral depletion, factors known to negatively impact brain and cardiovascular health.
Beyond stroke and dementia, regular consumption of diet and sugary sodas has also been linked to:
Obesity: 1.6 times increased risk per additional soda
Heart disease:
20% higher risk from just one can per day
Type 2 diabetes:
26% higher risk for those consuming 1 or 2 cans daily
Tooth decay and bone loss:
Due to sugar and acid erosion
Kidney damage:
From sodium and phosphoric acid damaging kidneys and bones over time
What happens inside your body within one hour of drinking a can of soft drink?
Immediately:
A flood of sugar enters your body with just one can.
Within 20 minutes:
Blood sugar spikes, triggering a surge of insulin.
Around 40 minutes:
Caffeine is fully absorbed, increasing blood pressure and causing the liver to release more sugar into the bloodstream. Dopamine surges stimulate the brain's pleasure centers.
After 60 minutes:
Phosphoric acid binds calcium and other essential minerals in your gut, while caffeine's diuretic effect causes these minerals to be flushed out through urine.
Expert recommendations and caution
Lead researchers emphasize that while the study shows a strong association, it does not prove that diet sodas directly cause stroke or dementia. They recommend moderation and suggest prioritizing water and natural beverages for daily hydration.
Public health authorities continue to review evidence on artificial sweeteners, but this research adds to the argument for cautious consumption, especially among older adults and those with existing health risks.
As more evidence emerges about the potential dangers of diet sodas and soft drinks, consumers should be aware of the possible long-term health implications. Choosing healthier hydration options and reducing reliance on artificially sweetened beverages may help lower the risk of serious neurological and cardiovascular conditions. Further studies are needed to fully understand the mechanisms behind these associations and to guide safe dietary choices.

New blood pressure guidelines urge zero alcohol and earlier hypertension treatment
The American Heart Association (AHA) and American College of Cardiology (ACC) have published new guidelines on the prevention and management of hypertension with their first major update in six years, as per CNN Health. The change that stands out most is the revision of the treatment initiation thresholds as well as the complete cessation of alcohol intake. AHA and ACC share new guidelines on the prevention of hypertension (Freepik) Hypertension Prevalence and Risks The AHA and ACC estimated that almost half of the adult population in the United States is classified as having hypertension. The World Health Organization calls hypertension is commonly called the 'silent killer' disease as it is mostly asymptomatic. The AHA and ACC further explain that in more severe cases, patients may have symptoms such as headaches, breathlessness, light-headedness, or epistaxis. It is important to control blood pressure as these symptoms tend to occur in the later stages of the illness. The thresholds have not changed, with the AHA and ACC defining normal blood pressure as less than 120/80 mmHg, elevated from 120-129/80 mmHg, and hypertension as 130 mmHg. Systolic blood pressure is the first number, a contraction of the heart, and the second number is the pressure during heart relaxation, or diastolic blood pressure. Also read: Doctor shares what happens when diabetes and hypertension co-exist, know the signs and lifestyle habits to better manage Key Changes in the New Guidelines Under the latest recommendations, people diagnosed with stage 1 hypertension with a systolic reading between 130 and 139 will first be directed to the diet and activity intervention stream. They will be advised on regular exercise, a healthy diet, low salt intake, and a regular routine. Now treatment is advised after three to six months with no lifestyle changes to diet. This is a shift from the 2017 guidelines, which usually started treatment at 140. Another big change is the guideline recommending no alcohol consumption whatsoever. Prior guidelines accepted alcohol intake in moderation. However, new studies show that alcohol is a risk factor for hypertension for most people. 'We put forward the ideal as abstinence,' Dr. Daniel Jones, the AHA guideline writing committee chair and a professor emeritus at the University of Mississippi School of Medicine, said. The guidelines also recommend limiting sodium intake to 2,300 mg a day, with 1,500 mg being optimum, alongside increasing potassium through food or potassium-containing salt substitutes. Additionally, following the DASH diet, which encourages intake of fruits and vegetables, whole grains, lean meat, and low-fat dairy, is beneficial. Adopting the right strategies is important in managing stress and healthy body weight. 150 minutes of exercise is ideal to see results. Individuals with a high body mass index are recommended to reduce 5% of their body weight. Women who are pregnant or planning to conceive a baby should closely monitor their blood pressure, as high BP can be harmful for both the mother and the child. Reducing blood pressure is beneficial for the kidneys, too, and reduces the risk of dementia. If Blood pressure is left unchecked, it can lead to other serious issues. Such as Kidney damage, heart disease, brain stroke, and loss of vision. Over time, it can also cause the blood vessels to be damaged and increase the risk of life-threatening problems such as coronary artery tamponade and cardiac arrest. If it is diagnosed and managed timely manner, it can lead to reversal of the disease, leading to a healthy life. FAQs Q1. What is considered high blood pressure? A1. A reading of 130/80 mmHg or higher. Q2. Can lifestyle changes lower blood pressure? A2. Yes, through diet, exercise, and stress management. Q3. Is there a need for medication at all? A3. Under normal circumstances, no, although medication may be necessary in the case of elevated readings.

Neuroscientist says this one exercise could protect your brain and keep memory strong for years
Alzheimer's disease affects an estimated 6.7 million older adults in the United States, a figure expected to double by 2060. While there is currently no cure, research suggests that certain lifestyle habits can help reduce the risk, and one particular type of exercise appears to be especially effective. Independence Day 2025 Before Trump, British used tariffs to kill Indian textile Bank of Azad Hind: When Netaji gave India its own currency Swadeshi 2.0: India is no longer just a market, it's a maker Dementia remains one of the biggest global health challenges of the 21st century. Alzheimer's, the most common form, is a progressive and irreversible condition that causes functional, cognitive, and behavioural decline. Age and genetics are known risk factors, but studies have found that around 35% of dementia risk is linked to modifiable factors such as high blood pressure in midlife, obesity, smoking, social isolation, hearing loss, depression, diabetes, and low physical activity. The Exercise That Stands Out Physical activity has long been recognised as a protective factor for brain health. However, according to a report in TOI, new research points towards a specific approach that may offer even greater benefits, dual-task exercise. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Undo Dr Robert W.B. Love, a neuroscientist specialising in Alzheimer's prevention, was quoted in TOI highlighting that this type of exercise involves engaging both the body and the mind at the same time. Dr Heather Sandison, a naturopathic doctor, was quoted as explaining in TOI that dual-task exercise means 'doing something physical while also challenging the brain', for example, walking while having a conversation. What Research Reveals A 2022 review, published in the Journal of Alzheimer's Disease and cited by TOI, examined how dual-task training, activities combining physical movement with mental challenges, affected older adults with cognitive decline. The review found that 2–5 weekly sessions, each lasting between 30 and 120 minutes, led to noticeable improvements in memory, attention, problem-solving, balance, and walking speed. Live Events The researchers also noted a surprising benefit: reduced levels of ß-amyloid, a protein linked to Alzheimer's disease. As reported in TOI, this is because dual-task activities require the brain to process information, coordinate movement, and maintain focus all at once. This simultaneous demand engages multiple brain networks, strengthens neural connections, and promotes neuroplasticity, the brain's ability to adapt and form new pathways. No Single Solution Experts emphasised, as reported in TOI, that no single habit can guarantee protection against Alzheimer's. The most effective strategy combines regular dual-task exercise with other healthy lifestyle choices, such as a balanced diet, staying socially engaged, and managing health conditions like hypertension and diabetes. The message is clear: while there is no magic bullet for preventing Alzheimer's, combining mental and physical stimulation through dual-task activities could be a valuable tool in preserving both cognitive skills and independence in later life.

Can Brisk Walking Help You Live Longer?
Brisk walking is a form of walking done at a faster pace than normal usually around 5–6 km/h. It's considered a moderate-intensity aerobic exercise that gets your heart pumping, improves blood circulation, and engages multiple muscle groups without putting excessive strain on the joints. Regular brisk walking can help maintain a healthy weight, lower blood pressure, improve cardiovascular fitness, strengthen bones, and even boost mood by releasing feel-good endorphins. Since it's low-impact and accessible to most people, it's one of the simplest yet most effective ways to improve overall health and fitness. It can also help you live longer because it supports heart health, improves lung function, enhances metabolism, and reduces the risk of chronic diseases like diabetes, hypertension, and certain cancers. Studies show that even 30 minutes of brisk walking most days can lower inflammation, improve insulin sensitivity, and strengthen the immune system, all of which contribute to a healthier, more resilient body as you age. It also boosts mental well-being, reducing stress and depression, which are linked to longevity. In short, this simple habit acts like a natural 'health insurance,' helping your body stay strong and active for more years. Keep reading as we share a list of ways in which brisk walking can help you live longer. Here are 10 ways brisk walking can help you live longer 1. Strengthens heart health Brisk walking raises your heart rate, improving blood flow and oxygen delivery throughout the body. Over time, it helps lower LDL ('bad') cholesterol, increases HDL ('good') cholesterol, and reduces the risk of heart disease which is one of the leading causes of premature death. A healthier heart means your body can function more efficiently for many years. 2. Controls blood pressure Walking at a brisk pace helps blood vessels stay flexible and reduces arterial stiffness, which can lower high blood pressure. Since uncontrolled hypertension is a major risk factor for strokes and heart attacks, keeping it in check directly contributes to a longer, healthier life. 3. Improves blood sugar regulation Brisk walking improves the way your muscles use glucose for energy, enhancing insulin sensitivity. This lowers the risk of type 2 diabetes and helps those already diagnosed to manage their condition better, preventing long-term complications that can shorten life expectancy. 4. Reduces inflammation Chronic inflammation is linked to diseases like cancer, Alzheimer's, and heart disease. Brisk walking promotes better circulation and reduces inflammatory markers in the body, lowering the chances of developing these life-shortening conditions. 5. Boosts lung capacity A faster walking pace requires deeper and more efficient breathing, which strengthens respiratory muscles and improves oxygen exchange in the lungs. Better lung function means your body can supply vital organs with the oxygen they need to function well over a lifetime. 6. Helps maintain a healthy weight Carrying excess weight strains the heart, joints, and metabolism. Brisk walking burns calories, supports fat loss, and helps maintain muscle mass. This balance reduces obesity-related risks such as heart disease, fatty liver, and sleep apnea, all of which can affect longevity. 7. Supports brain health Walking briskly increases blood flow to the brain, delivering oxygen and nutrients that protect against cognitive decline. Regular walkers have a lower risk of dementia, memory loss, and depression which helps preserve mental sharpness well into old age. 8. Strengthens bones and muscles The repetitive, weight-bearing nature of walking strengthens bones, reducing osteoporosis risk. Stronger bones and muscles lower the chance of falls and fractures, which are a major cause of disability and mortality in older adults. 9. Reduces stress and improves mood Walking outdoors, especially in nature, helps reduce cortisol (the stress hormone) and boosts endorphin levels. Chronic stress can weaken immunity and accelerate aging, so this natural mood boost indirectly supports a longer life. 10. Improves sleep quality Brisk walking can help regulate your circadian rhythm, making it easier to fall asleep and stay asleep. Good-quality rest supports cell repair, hormone balance, and immune function which are factors that are crucial for long-term health and longevity. Add brisk walking to your workout routine today to liver longer. Disclaimer: This content including advice provides generic information only.
