Don't eat these 7 foods if you're prone to cold sores
Cold sores are caused by the herpes simplex virus and can be both painful and disruptive. While a poor diet can weaken the immune system and increase susceptibility, certain healthy foods may also trigger outbreaks. According to a study published in NIH, foods high in arginine, an amino acid that the virus feeds on, are particularly linked to recurring cold sores. Being aware of these foods and limiting them can help reduce the frequency and severity of outbreaks. This guide highlights seven arginine-rich foods that are best avoided or moderated for anyone prone to cold sores while still supporting overall health. What are cold sores and its symptoms Cold sores, also known as fever blisters, are a common viral infection that appears as tiny, fluid-filled blisters on and around the lips, often grouped together in patches. When these blisters break, they form scabs that can last for several days, with the sores typically healing within two to three weeks without leaving scars. Cold sores are usually caused by herpes simplex virus type 1 (HSV-1), and less commonly by herpes simplex virus type 2 (HSV-2). They spread through close contact, such as kissing, and can be transmitted even when sores are not visible. Cold sore symptoms: Tingling and itching: A day or so before blisters appear, you may feel itching, burning, or tingling around the lips. Blisters: Small, fluid-filled blisters usually form along the border of the lips and sometimes around the nose, cheeks, or inside the mouth. Oozing and crusting: The blisters may merge, burst, and ooze, leaving shallow open sores that eventually crust over as they heal. 7 everyday foods that may trigger cold sore outbreaks Nuts Nuts are a staple of a healthy diet, packed with protein, fibre, and minerals, but they are also one of the worst triggers for cold sores. Peanuts, walnuts, and hazelnuts, in particular, contain high amounts of arginine, as do peanut butter and other nut spreads. Even dishes like curries or baked goods that include nuts can contribute to outbreaks, especially if combined with spicy ingredients that irritate sensitive skin. While nuts offer many health benefits, moderation is key for those susceptible to cold sores. Pumpkin Seeds and Other Seeds Seeds like pumpkin and sesame are highly nutritious but are also rich in arginine. These are commonly added to salads, smoothies, and baked goods, making them easy to consume in larger quantities than intended. For those with frequent cold sore flare-ups, reducing seed intake or substituting them with lower-arginine seeds, such as sunflower seeds in moderation, may help prevent triggers without compromising overall nutrition. Chocolate Chocolate is widely enjoyed, especially dark chocolate for its antioxidant content. However, darker varieties tend to have higher levels of arginine, which can provoke cold sore outbreaks. Even small amounts may be enough to trigger symptoms in sensitive individuals. During periods of high susceptibility, limiting chocolate consumption or opting for alternatives like carob may reduce the risk of an outbreak. Spirulina Spirulina, the blue-green algae celebrated for its superfood status, is often added to smoothies and protein shakes for its high nutrient content. Unfortunately, it is also rich in arginine. While it can support overall health, those prone to cold sores may need to avoid spirulina or use it sparingly to prevent flare-ups. Squash Squash, a favourite winter vegetable, is surprisingly high in arginine. While nutritious and versatile in soups and roasted dishes, squash can contribute to cold sore outbreaks in sensitive individuals. If you are susceptible, consider replacing squash with lower-arginine vegetables, such as carrots, zucchini, or bell peppers, to maintain a healthy diet without triggering symptoms. Oats Oats are a wholesome breakfast option, full of fibre and nutrients. However, they also contain a significant amount of arginine. For people prone to cold sores, this means that even a morning bowl of oatmeal could contribute to flare-ups. Swapping oats for alternatives like quinoa flakes, rice porridge, or other whole foods can offer similar nutrition while reducing arginine intake. Wheat Wheat is found in most breads, pastas, and baked goods, making it difficult to avoid completely. Its high arginine content can increase the likelihood of cold sore outbreaks. Opting for gluten-free grains, such as rice, buckwheat, or millet, is a practical way to enjoy baked and cooked dishes without the arginine overload. Cold sore prevention : Supplements, lysine-rich foods , and immune support Muscle-building supplements often contain concentrated arginine, which can trigger cold sore outbreaks. Those prone to cold sores should check supplement labels carefully and avoid products high in arginine. Balancing your diet with lysine-rich foods can help counteract arginine and reduce symptoms. Foods such as fish, beans, and dairy provide lysine and can be included alongside lower-arginine meals. Supporting your immune system with nutrients like vitamin C, vitamin D, zinc, and herbs such as echinacea may also help prevent outbreaks. Topical treatments like petroleum jelly or bio-propolis ointments can soothe blisters, while antiviral medications are available for persistent cases. Cold sores are caused by the herpes simplex virus type 1 (HSV-1), which remains dormant in the body after the initial infection. Outbreaks are often triggered by stress, weakened immunity, or environmental factors. Foods high in arginine can exacerbate this, making dietary awareness a valuable part of cold sore management. By being mindful of high-arginine foods and balancing them with lysine-rich options, you can reduce the frequency and severity of cold sore outbreaks while maintaining a healthy, nutrient-rich diet.

Why many women over age 52 have a higher risk of getting STIs
STIs are on the rise — but it's not just frat bros and free-lovers feeling the burn. While younger people still account for the majority of cases, studies show that some of the steepest spikes are happening in people 55 and up. Experts have offered several explanations for the surge, but research suggests there's a risk factor affecting many midlife and older women that has largely flown under the radar and could be playing a key role. Advertisement 4 More Americans are having sex in their senior years thanks to advancements in medicine. Monkey Business – More than a million American women hit menopause each year — and it's not just hot flashes and mood swings they're facing. The transition, which wraps up around age 52 on average, marks the end of reproductive years and is driven by a drop in estrogen as the ovaries slow hormone production. While vaginal dryness and loss of elasticity are well-known symptoms, research from Ohio State University (OSU) shows that menopause can also weaken the vaginal tissue itself, making it more prone to tearing. Advertisement That vulnerability comes down to changes at the cellular level. The vagina's surface is made up of multiple layers held together by key proteins like desmoglein-1 (DSG1) and desmocollin-1 (DSC1). 'These proteins strengthen the vaginal lining and restrict pathogen access to deeper tissue, reducing the risk of infection,' Dr. Thomas L. Cherpes, associate professor of otolaryngology at OSU, wrote in The Conversation. Advertisement 4 Menopause can bring a host of uncomfortable symptoms, including vaginal changes. – In their research, Cherpes and his colleagues found that postmenopausal women have significantly lower levels of DSG1 and DSC1 than women who haven't gone through the transition. To see how this might impact infection risk, the researchers removed the ovaries of mice in a lab to mimic estrogen loss in postmenopausal women. Compared to mice with intact ovaries, those without had far lower levels of DSG1 and DSC1 in their vaginal tissue. Advertisement The team also found that these mice were more vulnerable to infection with herpes simplex virus type 2 (HSV-2), which causes genital herpes. They were less able to clear chlamydia infections from the lower genital tract as well. The findings help explain why postmenopausal women are more susceptible to STIs than their younger counterparts. Notably, when Cherpes and his colleagues applied estrogen cream to the mice without ovaries, it restored the vaginal lining's integrity and fully protected them from HSV-2 infection. 4 The vaginal tissue is more vulnerable to tearing after menopause, opening the door to infection. megaflopp – 'While additional research is needed, findings from our lab suggest that estrogen-containing compounds used to relieve vaginal irritation and other symptoms of genitourinary syndrome of menopause can also reduce susceptibility to STIs among older adults,' Cherpes wrote. Sex doesn't stop — and neither do the risks Americans might not like to talk about it, but older adults are still very much having sex. A 2018 survey found nearly 40% of people aged 65 to 80 are sexually active, and almost two-thirds remain interested in sex. Advertisement More recent AARP data shows that 26% of 60- to 69-year-olds and 17% of those 70 and older have sex weekly. 'Hormone-replacement therapy, vaginal lubricants and the approval of sildenafil (Viagra) and its relatives have extended people's sex lives,' Dr. Sandra Adamson Fryhofer told the American Medical Association. But while more people are living longer and staying sexually active, more are also paying the price. 4 Sex-crazed seniors are fueling a major spike in STIs nationwide. David – Advertisement 'Rates are highest in the under 25 age group, which accounts for about 50% of STIs, but we're definitely seeing a rise in infections in the older population, particularly in people over 65,' Dr. Angelina Gangestad said in an interview with University Hospitals. Between 2010 and 2023, the number of Americans over 65 diagnosed with chlamydia, gonorrhea or syphilis rose by roughly three-, five- and sevenfold, respectively, according to the Centers for Disease Control and Prevention. Research also suggests women over 50 are at greater risk for HIV than their younger peers. Advertisement In addition to the effects of menopause, experts say several other factors are likely fueling the rise. Condom use is significantly lower among older adults compared to younger people. One study found that just 3% of Americans aged 60 and older have used a condom in the past year. Older adults also tend to have less knowledge about STIs, including how they spread, what symptoms look like and how to prevent them. Advertisement To make matters worse, research suggests that many doctors don't ask older patients about their sex lives — and seniors aren't exactly jumping to bring it up with their family or friends, either. 'No one wants to think about grandma doing this,' Matthew Lee Smith, an associate professor at the Texas A&M School of Public Health, told NBC News. 'You certainly aren't going to ask grandma if she was wearing condoms — and that's part of the problem, because every individual regardless of age has the right to intimacy.'

The best herpes test kits for 2025, according to experts
Herpes affects billions of people around the world. In fact, the World Health Organization reports that 3.8 billion people under the age of 50 have herpes simplex virus type 1 (HSV-1), the main cause of oral herpes, while an estimated 520 million people ages 15 to 49 have herpes simplex virus type 2 (HSV-2), the main cause of genital herpes. Yet, despite how prevalent this infection is, when going to your doctor specifically for a sexually transmitted infection (STI) panel, herpes is not typically included in the screening. Fortunately, there are at-home herpes test kits that can give you the answers you need without a trip to the doctor."At-home tests are generally reliable when used correctly," says Dr. Stephanie Hack, board-certified obstetrician and gynecologist. In the U.S., where there are roughly 572,000 new cases of genital herpes in individuals between the ages of 14 and 49 each year, at-home testing can be a reliable part of regular sexual health screenings. But Dr. Hack notes that not all herpes tests are created equal. A key point to keep in mind — you don't want to buy just any old test and hope for the best. When it comes to testing for herpes, you want to make sure the test you choose is accurate and easy to help us understand what to look for in the best at-home herpes tests, we spoke with a panel of four medical experts who specialize in sexual and reproductive health to get their input on self-administered herpes tests. We then used the experts' input and my own experience as a health care professional and health journalist to research the top OTC herpes tests, rating each based on cost, ease of use, time to receive results and any additional medical support offered. Here are our picks for the best at-home herpes tests for a range of needs. However, if you're concerned about other sexually transmitted infections as well, consider our top picks for the best at-home STD tests and best at-home syphilis tests. Best at-home herpes test overall Other top at-home herpes tests we recommend for 2025 Factors to consider when choosing an at-home herpes test How we chose the best at-home herpes test FAQs Meet our experts Update, July 2, 2025: We checked all product prices and availability. Our No. 1 pick for the best at-home herpes test remains unchanged. (back to top) (back to top) Choosing the right herpes test for you is a personal decision that depends on your specific needs. Before making a decision, it's a good idea to consider certain factors: Type of test: HSV-1 is generally considered the virus responsible for oral herpes, whereas genital herpes is associated more with HSV-2. However, since genital herpes can come from either herpes virus, tests that look for both types of of the virus tend to be more accurate. On the other hand, tests that screen only for HSV-2 are typically more cost-effective. Collection method: Herpes can be detected using a blood sample or a swab of the lesion if an outbreak is present. According to Dr. Jill Purdie, board-certified ob/gyn in Alpharetta, Ga., taking a swab of the sore itself is the most accurate type of test, but it's also more prone to user error than a blood sample. A swab sample also requires an active outbreak, whereas a blood test can determine whether or not you've been exposed to the virus even when an outbreak is not present. Time until results: The last thing you want to do when getting an STD test is sit around and wait for the results. Certain tests offer shorter wait times, while others might take a bit longer. All the tests on this list have a turnaround time of between one and five days. Medical support included: If you test positive, does the company offer any type of medical support? If a medical consultation is available, is it free or does it cost extra? Additionally, is treatment or a prescribing provider available? Cost: Along with the cost of the actual test, consider whether or not there are additional fees for shipping, follow-up support or treatment options. Also, consider whether or not FSA/HSA payments are accepted. Accuracy: For the most accurate results, look for a company that uses CAP- and CLIA-certified labs. Privacy: Most at-home herpes tests don't accept insurance or require extensive identifying information outside of name and address, which can go a long way toward protecting your privacy. Additionally, look for a company that offers discreet packaging when shipping. (back to top) To find the best at-home herpes tests on the market today, we first consulted a panel of medical experts who specialize in sexual health, urology and reproductive and women's health. Our team then researched a broad range of at-home HSV tests and rated each based on cost, the type of herpes viruses tested, accuracy, collection method and turnaround time. In addition, we considered the company's reputation and follow-up support. Specifically, we looked at whether or not the option for a health care consultation or treatment was available. After compiling the data, we narrowed our list of the best herpes tests based on specific testing needs, such as turnaround time and additional medical support. (back to top) Herpes is primarily detected in one of two ways: through antibodies in the blood or by the presence of the virus in a lesion. Urine tests are less common but can be used in combination with another sample method to ensure accuracy. To date, there are not any fully at-home rapid tests that can detect the herpes virus, so all "at-home" tests require you to pre-purchase the test online, then collect the sample yourself and mail it to the lab or visit a certified lab to have the sample specimen taken for you. Regardless of the option you choose, at-home herpes enable you to get tested without making an appointment with your primary care doctor. Herpes is a virus that causes skin infections and painful sores on the body, primarily around the mouth and genital areas. Aleece Fosnight, a board-certified physician assistant specializing in sexual medicine, women's health, and urology, tells us: "There are several types of herpes including varicella-zoster, the virus responsible for chicken pox. But the herpes simplex virus — or HSV — comes in two forms: HSV-1 mainly causes oral herpes — also known as cold sores HSV-2 is associated with genital herpes HSV-1 is spread through skin-to-skin contact and saliva and mainly causes oral herpes, also known as cold sores. HSV-2, on the other hand, is usually spread through sexual contact, resulting in genital herpes. Although herpes is most contagious during an outbreak, herpes simplex 1 and 2 can also be transmitted when there are no visible sores or symptoms. Unlike most other STDs that can only be spread through bodily fluids, HSV-1 and 2 can be transmitted through close skin-to-skin contact. "Both types of herpes can cause small, painful blisters around the site of the infection," says Dr. Rashid Bani, medical director at Your Sexual Health. Moreover, both types can infect your face or genitals. Although HSV-2 is responsible for most cases of genital herpes, you can get genital herpes from HSV-1 (and vice versa). Painful sores or blisters are the most common symptom of herpes, Purdie tells us. With oral herpes, there is typically just one blister, whereas genital herpes often appears in a cluster. Other common signs can include: Fever or flu-like symptoms Headaches Body and muscle aches Swollen lymph nodes in the neck or groin area Tingling, burning or itching sensation Unusual vaginal discharge Painful urination It's important to note, though, that not everyone who's infected with herpes will show symptoms. In fact, most people with HSV are asymptomatic and may not even realize they have it. You should get tested if you begin to experience symptoms or notice any sores around your genitals, says Hack. One exception would be if you've had sex with a partner who has genital herpes. In that case, it's important to remember that it can take time for your body to develop HSV antibodies. The incubation period for herpes is typically two to 12 days, but it can take even longer. In some cases, it can take up to 16 weeks or more for HSV to be detected in your blood, Fosnight says. Our experts agree that at-home tests are generally reliable when used correctly, so it's crucial you follow the directions for sample collection exactly as stated by the company. While the most accurate way to detect herpes is through a viral culture or PCR test via a swab of the blister or lesion, "blood tests, which look for HSV antibodies in a blood sample, can be used if you don't have an active outbreak or sore," says Hack. If you test positive for herpes, the next step should be to consult a healthcare provider to discuss possible treatment options. While there is no cure, treatments are available to help speed up healing, prevent or shorten outbreaks and reduce the chances of spreading it to partners. Your doctor may also advise getting retested after a positive test result, especially if you have no symptoms. "No HSV test is perfect, and false results can occur," says Hack. For example, one study found that herpes IgM testing resulted in many false positives for HSV-2 and many false negatives for HSV-1. False negatives can occur if the infection is very new since your body hasn't developed the antibodies yet. On the other hand, false positives can occur due to cross-reactivity. Antibody tests can sometimes react to other viruses in the same family (e.g., HSV-1 or the varicella-zoster virus). In other words, you may test positive for herpes type 2 when, in fact, you only have type 1. Because of that, it's always a good idea to discuss your results and sexual history with a doctor.

Understanding herpes risks for pregnant mothers and babies
The virus is highly contagious and can be transmitted through direct contact with an infected person's bodily fluids, including saliva or genital secretions. Neonatal herpes, a rare but potentially life-threatening condition, occurs when a newborn contracts the virus during delivery. - Photo illustrated by Sinar Daily SHAH ALAM – Herpes, caused by the herpes simplex virus (HSV), is a common viral infection presenting in two primary forms: HSV-1, typically linked to oral infections and HSV-2, which usually causes genital infections. The virus is highly contagious and can be transmitted through direct contact with an infected person's bodily fluids, including saliva or genital secretions. While herpes infections are often manageable, they can lead to severe complications, particularly for newborns. - 123RF photo While herpes infections are often manageable, they can lead to severe complications, particularly for newborns. Neonatal herpes, a rare but potentially life-threatening condition, occurs when a newborn contracts the virus during delivery. KPJ Damansara Obstetrics and Gynaecology specialist, Professor Dr Imelda Nasreen Nasruddin @ Balchin, shared a poignant case describing the dangers of neonatal herpes. "In 1999, I witnessed an 11-day-old baby brought into the emergency department, who sadly passed away. "A post-mortem revealed that the baby's liver was filled with herpes simplex virus infection, which was the cause of death," she shared in her Facebook post. Upon further investigation, she said the mother admitted to having experienced a genital herpes infection about a month before giving birth but had not informed the midwife. "Now, medical guidelines recommend that if a pregnant mother contracts a genital herpes simplex virus infection within six weeks before her due date, the advice is to deliver via Caesarean section to protect the baby from contracting HSV," she said. Genital herpes in pregnant women often goes unnoticed, as symptoms can range from painful sores to mild irritation or even no symptoms at all. What is Herpes? Herpes is classified into two primary types: HSV-1 (oral herpes): Commonly associated with cold sores or fever blisters around the mouth and face. HSV-2 (genital herpes): Typically affects the genital and anal areas but can also occur in other parts of the body. The virus is highly contagious and can be transmitted through direct contact with an infected individual, including kissing, sharing utensils, or sexual contact. Symptoms and Diagnosis While many infected individuals experience mild or no symptoms, others may have painful sores, itching, or burning sensations in affected areas. Recurrences are common, as the virus remains dormant in the body and can reactivate during periods of stress, illness, or weakened immunity. Diagnosis is often made through physical examinations and laboratory tests such as swabs from sores or blood tests. More Like This

Cold sores may play role in Alzheimer's development, new research reveals
Cold sores may play a role in the development of Alzheimer's disease, according to a new study published in BMJ Open. Researchers examined 344,628 "case-control pairs." The pairs were matched in age, sex, geographical region and number of healthcare visits — but one had Alzheimer's disease and one did not. Of the groups studied, 1,507 people with Alzheimer's also had herpes simplex virus type 1 (HSV-1), which is the most common cause of cold sores. Only 823 people in the control group had HSV-1. First Blood Test For Alzheimer's Diagnosis Cleared By Fda Among these 2,330 people, 40% used anti-herpetic medication following their diagnosis. Those who were treated for the virus were 17% less likely to develop Alzheimer's disease than those who didn't use the treatments, the study found. Read On The Fox News App The risk of developing this form of dementia is known to rise with age. However, the chance of an HSV-1 diagnosis was 80% higher in those diagnosed with Alzheimer's, according to the research. Less commonly, cold sores can be caused by herpes simplex virus type 2 (HSV-2). Alzheimer's Disease Could Be Prevented By Antiviral Drug Already On Market The analysis places "an even greater emphasis on viewing the prevention of herpes viruses as a public health priority," the researchers said in a press release. Overall, women made up 65% of the Alzheimer's cases. Their average age was 73, and they tended to have more co-existing conditions, which were all risk factors. The study also observed the potential role of other herpes viruses, some of which were associated with an elevated risk of Alzheimer's disease. The specific connection between viruses like HSV-1 and heightened dementia risk isn't clear, the researchers noted. Click Here To Sign Up For Our Health Newsletter "However, studies have shown that inflammatory alterations in the brain caused by HSV infection are pivotal in [Alzheimer's disease] development," they said in the release. Treatment with anti-viral therapy seems to lower the risk of Alzheimer's, "suggesting that HSV-1 treatment may be protective," the study says. "There's no cure for cold sores, but treatment can help manage outbreaks," according to Mayo Clinic. "Prescription antiviral medicine or creams can help sores heal more quickly. And they may make future outbreaks happen less often and be shorter and less serious." There were some limitations in the study, the researchers acknowledged. "Due to limited data history, HSV-1 infections prior to the patient's database entry were not included in the analysis, and it is possible that some overlap exists between HSV-1 and HSV-2 diagnoses," the researchers noted. "Additionally, many individuals with HSV-1 infection are asymptomatic, and others may not seek medical care during recurrences and are therefore not clinically diagnosed and recorded in the database." While an estimated two-thirds of people under 50 are infected with HSV-1, data on symptomatic infections is limited, "as manifestations can be mild or unnoticed," the researchers added.
