Now, a new study has found promising evidence about the potential role of a specific vitamin in supporting cognitive function.</p><p>Researchers from <b>Emory University</b> examined whether <b>vitamin D</b> supplement intake was associated with cognitive function in people with mild cognitive impairment (MCI) and disrupted sleep. The findings were published in the journal <i>Sleep Medicine</i>.</p><p>The study focused on <b>54 adults</b> with diagnosed or suspected MCI who also reported sleep problems. MCI is a condition involving changes in memory and other thinking abilities that are greater than expected with normal aging but do not necessarily interfere significantly with daily activities.</p><img src="https://www.cronista.com/resizer/v2/UPZNNYCM6ZHEVMLQIKAXUOBP6A.jpg?auth=b9dbe29f58eb432560da8af382a496e11b007d5762ae7c2ec6c6e42e95143fa4&smart=true&width=1200&height=900" alt="A new study suggests that a common vitamin could be linked to better cognitive performance in older adults experiencing both memory problems and sleep disturbances." height="900" width="1200"/><p>Participants completed the <b>Montreal Cognitive Assessment (MoCA)</b>, a screening tool commonly used to evaluate cognitive abilities. They also reported whether they took vitamin D supplements and, if so, the type and daily amount.</p><h2>What the researchers found about vitamin D and cognition</h2><p>Participants who reported taking <b>5,000 IU or more of vitamin D per day</b> had higher MoCA scores than those who did not take vitamin D supplements. The association remained after researchers adjusted for factors including age, sex, body mass index, vitamin D type and education.</p><p>The researchers also found that the results did not significantly differ between people taking <b>vitamin D2</b> and those taking <b>vitamin D3</b>. Lower doses of vitamin D were not significantly associated with differences in overall MoCA scores.</p><p>The study’s authors described the findings as an indication that higher daily vitamin D intake may be associated with better cognition in people experiencing both <b>sleep disturbances and mild cognitive impairment</b>. They said this population may represent an important stage for studying factors that could potentially be modified as cognitive changes emerge.</p><p>Sleep problems are particularly relevant in this population. The researchers noted that sleep disturbances affect a substantial proportion of people with MCI and that sleep problems and cognitive decline may be interconnected.</p>]]></content:encoded><media:content url="https://www.cronista.com/resizer/v2/D7E6JQIBLNHOXNZROP2WBFYMVM.jpg?auth=848212e83789b3e22ceb81d660922638a5f3a282a900094917537bc6740f7e66&amp;smart=true&amp;width=1200&amp;height=900" type="image/jpeg" height="900" width="1200"><media:description type="plain"><![CDATA[New scientific study reveals how a single vitamin could improve cognition in adults with memory and sleep problems.

But how effective is it really?</p><p>Scientific research suggests that the answer depends largely on <b>the concentration of hydrogen peroxide, the microorganism being targeted and how long the surface remains in contact with the solution</b>.</p><p>A study published in the <i>Journal of Food Protection</i> tested several household products against three foodborne pathogens: <b>Listeria monocytogenes, Escherichia coli O157 and Salmonella Typhimurium</b>. </p><p>Researchers tested hydrogen peroxide at concentrations of <b>1.5% and 3%</b>, along with vinegar, baking soda, bleach and other household compounds.</p><h2>What science says about hydrogen peroxide as a disinfectant</h2><p>The study found that <b>3% hydrogen peroxide</b> produced a greater than 5-log reduction in both <i>Salmonella Typhimurium</i> and <i>E. coli O157</i> after <b>one minute at 25°C</b>. A 5-log reduction corresponds to a reduction of 99.999% in the number of microorganisms under the conditions of the test.</p><p>However, the results were not identical for all three pathogens. <i>Listeria monocytogenes</i> was more resistant to the tested household compounds, and greater reductions were observed when the hydrogen peroxide treatment lasted <b>10 minutes at an initial temperature of 55°C</b>.</p><img src="https://www.cronista.com/resizer/v2/CV272XVWLVCKRAIMXVFGXAITCY.jpg?auth=ce5aea20324f2081c5408118a643fb67ed01b209d71977ee7db025327ff334a1&smart=true&width=1200&height=900" alt="Researchers tested hydrogen peroxide at concentrations of 1.5% and 3%, along with vinegar, baking soda, bleach and other household compounds." height="900" width="1200"/><p>The researchers compared the effectiveness of the products and found that, among the substances tested, <b>household bleach was more effective than 3% hydrogen peroxide</b>, followed by undiluted vinegar and other acidic compounds. Baking soda showed the lowest effectiveness against the pathogens tested.</p><p>The findings therefore suggest that hydrogen peroxide can have meaningful antimicrobial activity, but its effectiveness cannot be generalized to every type of bacteria or every household cleaning situation.</p><h2>The CDC also recognizes hydrogen peroxide as a disinfectant</h2><p>The <b>Centers for Disease Control and Prevention (CDC)</b> lists hydrogen peroxide among chemical disinfectants with documented germicidal activity. According to the agency, hydrogen peroxide has <b>bactericidal, virucidal, sporicidal and fungicidal properties</b> and is active against a wide range of microorganisms.</p><p>The CDC explains that hydrogen peroxide works by producing destructive hydroxyl free radicals that can damage <b>cell membranes, DNA and other essential components of microorganisms</b>. The agency also notes that commercially available <b>3% hydrogen peroxide is a stable and effective disinfectant when used on inanimate surfaces</b>.</p><p>The concentration and contact time are important. CDC-reviewed research found that a <b>0.5% accelerated hydrogen peroxide</b> formulation demonstrated bactericidal and virucidal activity within one minute and mycobactericidal and fungicidal activity within five minutes. Other studies cited by the agency found different exposure times depending on the concentration and microorganism involved.</p><p>This means that simply applying hydrogen peroxide to a surface and immediately wiping it away may not produce the same disinfecting effect observed in laboratory tests. <b>The product’s concentration and the required contact time matter.</b></p>]]></content:encoded><media:content url="https://www.cronista.com/resizer/v2/VA3L7WLSHVGJPAQLZ7IYIHHKEY.jpg?auth=1c6bc10e6de15c9949eae132c728ba363718b3bae574b60f732903a4770f4c66&amp;smart=true&amp;width=1200&amp;height=900" type="image/jpeg" height="900" width="1200"/></item><item><title><![CDATA[Mars begins its 38th year: How long a year lasts on the Red Planet]]></title><link>https://www.cronista.com/en/health-science/mars-begins-its-38th-year-how-long-a-year-lasts-on-the-red-planet/</link><guid isPermaLink="true">https://www.cronista.com/en/health-science/mars-begins-its-38th-year-how-long-a-year-lasts-on-the-red-planet/</guid><dc:creator><![CDATA[Oriana Luna]]></dc:creator><description></description><pubDate>Thu, 01 Oct 2026 19:53:43 +0000</pubDate><content:encoded><![CDATA[<p>On September 30, 2026, the Red Planet began its 38th year according to the Martian calendar, marking the start of another orbit around the Sun.

The beginning of a new Martian year coincides with the northern spring equinox, when spring begins in <b>Mars’ northern hemisphere</b>, and autumn begins in its southern hemisphere.</p><p>The current system for numbering Martian years dates back to 1955. That year was designated as the beginning of the first Martian year after a major global dust storm observed on the planet in 1956.</p><p>Mars also has four seasons, like Earth, but they do not all last the same amount of time.

Researchers found that <b>42.6% of the runners reported an injury during the training period</b> <b>or the race</b>, with the foot and knee among the most commonly affected areas.</p><p>The research highlights how common injuries can be among marathon runners. More recently, sports medicine doctors, physical therapists, and running coaches interviewed by <i>The New York Times</i> identified several habits that can help runners reduce their risk of injury.</p><h2>Build mileage gradually</h2><p>Increasing your running distance too quickly can place more stress on the body than it can safely handle. Sports medicine experts recommend <b>gradually increasing weekly mileage rather than making large jumps in training volume</b>.</p><p>One general guideline cited by experts is to increase total weekly mileage <b>by no more than 10% to 20%</b>. Runners preparing for a marathon may also benefit from giving their bodies at least 12 to 16 weeks to adapt to the increased workload, particularly if they are new to the distance.</p><h2>Keep easy runs at an easy pace</h2><p><b>Not every training session needs to be intense</b>. Experts recommend keeping most long runs at a genuinely easy pace, allowing runners to build aerobic endurance without constantly placing their bodies under high stress.</p><p>One practical way to measure <b>the effort is the ability to maintain a conversation without struggling for breath</b>. Runners training with a group or using fitness apps may feel pressure to increase their pace, but matching someone else’s speed is not necessarily appropriate for every workout.</p><h2>Make time for rest and recovery</h2><p>Rest is an important part of training because the body needs time to recover after physical stress. Experts recommend including recovery days rather than filling every day with demanding workouts.</p><p><b>Sleep is also part of recovery</b>. According to sports medicine experts, adequate sleep can help the muscles and bones repair themselves and may also affect athletic performance.</p><h2>Add strength training to your routine</h2><p>Running alone does not necessarily develop all of the strength needed to support the body during training. Experts recommend strengthening the legs, glutes, and core to address weaknesses and improve stability.</p><p>Exercises such as squats, lunges, Romanian deadlifts, glute bridges, and planks can target these areas. A simple routine performed at least twice a week can be enough to complement running, with the difficulty gradually increasing over time.</p><img src="https://www.cronista.com/resizer/v2/CMM7MXIAVNAAVAEANRYI3H3SOE.jpg?auth=9660d21a67ed2d507fbb2d9c069df425a6cd1e04c7b1fa632876d78897c8352a&smart=true&width=1200&height=900" alt="Experts recommend several habits that can help runners reduce their risk of injury during training." height="900" width="1200"/><h2>Do not ignore persistent pain</h2><p>Continuing to train through recurring pain can allow a minor problem to become more serious. <b>Experts recommend paying attention when discomfort persists</b> or worsens during training rather than simply hoping it disappears.</p><p>Persistent pain can also affect a runner’s gait, potentially placing additional stress on other parts of the body. If pain continues or gets worse, sports medicine specialists recommend having it evaluated.</p><h2>Use fitness trackers as a tool, not a coach</h2><p>Running watches and fitness apps can help runners monitor distance, heart rate, and other training information. However, experts caution against relying exclusively on metrics such as a device’s “readiness score” to determine how hard to train.</p><p><b>Technology</b> cannot account for every factor affecting performance and recovery, including weather, terrain, and other forms of physical or life stress. Experts recommend paying attention to how your body feels and adjusting training accordingly.</p><p>The 2024 marathon study underscores why injury prevention matters: <u>injuries were reported by 38.4% of runners during training, while 14.1% of those who started the marathon reported an injury that affected their finishing time or required medical care afterward</u>. Overall, 50.1% of the runners who reported an injury received medical care.</p>]]></content:encoded><media:content url="https://www.cronista.com/resizer/v2/KY3V5CDIGBDPRKBEINEGDK25IE.jpg?auth=9d4aa0c499b3baad2060cacd591d5922c38b94c73b436a78816ccf2d56ead0e3&amp;smart=true&amp;width=1200&amp;height=900" type="image/jpeg" height="900" width="1200"><media:description type="plain"><![CDATA[Sports medicine experts recommend gradually increasing weekly mileage rather than making large jumps in training volume.]]></media:description></media:content></item><item><title><![CDATA[There are new “bad cholesterol” values considered healthy: nearly 1 in 3 people without previous illnesses do not meet them]]></title><link>https://www.cronista.com/en/health-science/there-are-new-bad-cholesterol-values-considered-healthy-nearly-1-in-3-people-without-previous-illnesses-do-not-meet-them/</link><guid isPermaLink="true">https://www.cronista.com/en/health-science/there-are-new-bad-cholesterol-values-considered-healthy-nearly-1-in-3-people-without-previous-illnesses-do-not-meet-them/</guid><dc:creator><![CDATA[Nicolás Sanles]]></dc:creator><description></description><pubDate>Wed, 30 Sep 2026 14:17:45 +0000</pubDate><content:encoded><![CDATA[<p>The<a href="https://www.heart.org/en/health-topics/cholesterol/about-cholesterol/what-your-cholesterol-levels-mean" target="_blank" rel="noreferrer" title="https://www.heart.org/en/health-topics/cholesterol/about-cholesterol/what-your-cholesterol-levels-mean"><b> American Heart Association</b></a> explains that “<b>bad cholesterol</b>” or LDL is the kind that can build up in the arteries and, over time, narrow them, increasing the risk of cardiovascular problems.</p><p>This year, the new guideline from the <b>American Collage of Cardiology/American Heart Association</b> changed the game as far as LDL cholesterol is concerned: <u>a cardiovascular risk calculator was added and the goals were adjusted according to each patient’s risk.</u></p><p>Within the field of <b>health</b>, a common goal is to keep these levels regulated through lifestyle.

That tray is now at the center of a recall affecting shoppers across the <b>United States</b>.</p><p><b>Gias Foods</b>, based in<b> New York</b>, is recalling two lots of <i><b>bettergoods Authentic Italian Lemon Alfredo Fettuccine</b></i> because the product may be contaminated with <b>Listeria monocytogenes</b>. </p><p>The company’s announcement was posted by the FDA on September 15, 2026. As the agency itself makes clear, it publishes these notices as a public service and does not endorse either the product or the company.</p><h2>What the product is</h2><p>It is a frozen pasta sold under the bettergoods brand and distributed nationwide at Walmart stores. Its popularity is explained by its reach: it made its way onto shelves across the country. The affected product can be identified as follows:</p><ul><li>Yellow plastic package, 22 oz.</li><li>UPC 194346442706.</li><li>Lot L6079C or L6080C.</li><li>Expiration date 09/19/2027 or 09/20/2027, stamped on the back of the package.</li></ul><img src="https://www.cronista.com/resizer/v2/WGZQDODWQVFQLDVT5L6E32KCOE.jpeg?auth=ca42213ab7e0a3279e0d4fbda4399216c5cb2121c1f3b5000e3e4da6f8d82016&smart=true&width=1200&height=900" alt="Gias Foods, based in New York, is recalling two lots of bettergoods Authentic Italian Lemon Alfredo Fettuccine because the product may be contaminated with Listeria monocytogenes. " height="900" width="1200"/><h2>How the problem was detected</h2><p>The recall did not stem from consumer complaints. According to the company, it resulted from a routine sampling program run by the <b>Washington State Department of Agriculture</b> and the <b>Florida Department of Agriculture and Consumer Services</b>. </p><p>Those tests indicated the finished product may contain the bacteria. Gias Foods has stopped distribution, and both the FDA and the company are still investigating what caused the problem. No illnesses have been reported to date.</p><p><b>Listeria can cause serious and sometimes</b> <b>fatal infections in young children, elderly or frail people, and those with weakened immune systems</b>. In healthy people it usually causes short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea. In pregnant women, however, the infection can cause miscarriages and stillbirths.</p><p>As the <b>FDA </b>notes, <b>this bacterium can survive and grow even under refrigeration</b>. The <b>CDC </b>describes two forms of illness. One is a milder gastrointestinal form, with fever, muscle aches, nausea, vomiting and diarrhea lasting one to three days. The other is an invasive form, which occurs when the bacteria spread beyond the intestines and can include headache, stiff neck, confusion, loss of balance and seizures. </p><p>This second form is especially dangerous for newborns, adults over 65 and people with weakened immune systems. During pregnancy, symptoms may be mild or go unnoticed and still have serious consequences.</p><h2>What consumers should do</h2><ol><li><b>Check the freezer.</b> Look for a 22 oz tray of this fettuccine and verify the UPC, lot number and date on the back of the package.</li><li><b>Don’t eat it if it matches.</b> Anyone with a product from the listed lots should return it to the place of purchase for a full refund.</li><li><b>Contact the company.</b> Questions can be sent to sales@giasfoods.com, with a response promised within 24 hours.</li><li><b>Watch for symptoms.</b> Anyone who has eaten the product, especially those in a high-risk group, should monitor for symptoms and consult a health professional if any appear.</li></ol>]]></content:encoded><media:content url="https://www.cronista.com/resizer/v2/PDDDXRAFGBCMTGSDG3YIKIB4ZU.jpg?auth=532265bc4170f3feb2e431c1e5af4c631fae077330650e7c6de304ef1b888d6f&amp;smart=true&amp;width=1200&amp;height=900" type="image/jpeg" height="900" width="1200"><media:description type="plain"><![CDATA[FDA announced the recall of a popular pasta due to potential Listeria contamination.
