Dining out is a popular pastime, but it's essential to be aware of potential food safety risks. We all have our go to foods whenever we are at a restaurant and enjoy the prospect of getting to eat their favorite meal. But even in the most high-end restaurants, the risk of getting sick always lingers. You never know when or what may cause issues for you

Food poisoning is a common problem that can lead to things like nausea, diarrhea, vomiting, and stomach upset. The Centers for Disease Control and Prevention (CDC) estimates that about 48 million people in the United States get sick from food poisoning each year. While sometimes it is unavoidable, being aware of these things can help you understand things that can go wrong and taking precautions when eating at restaurants. It's crucial to be informed to protect your health and enjoy your dining experience without worry. Here are some foods you should either avoid or be careful while eating.

Foods You Should Be Careful About While Dining Out

Eggs

Even eggs that look fine can have Salmonella bacteria. These bacteria can make you sick with stomach cramps, diarrhea, fever, and vomiting. Restaurants can cause outbreaks if they don't cook eggs to 160 degrees Fahrenheit, store them at the wrong temperature, use unpasteurized eggs, or use dirty cooking tools. These bad practices let bacteria grow and make people sick. So, it's important to cook and handle eggs the right way.

Pre-Cut Melons

Melons that are cut up ahead of time, like in fruit salads, are more likely to cause food poisoning. When you cut a melon, bacteria on the outside can get to the inside. If lots of fruit is cut in one place, it's easier for bacteria to spread. Since people eat melons raw, there's no cooking to kill the germs. These germs, like Listeria, Salmonella, or E. coli, can make you really sick. So, be careful with pre-cut melons.

Sprouts

Sprouts are healthy, but they grow in warm, wet places where bacteria like Listeria like to live. Even washing sprouts doesn't always get rid of these germs. And because people usually eat sprouts raw, there's no cooking to kill the bacteria. This makes sprouts a big cause of food poisoning. There have been lots of outbreaks linked to sprouts, with many people getting sick and even ending up in the hospital. So, it's a good idea to avoid sprouts, especially at restaurants.

Undercooked Meat

Meat that isn't cooked enough can have harmful bacteria like Salmonella, E. coli, and Campylobacter. Campylobacter is a common cause of diarrhea. Ground beef is extra risky because it's often made from meat from many different cows. If one cow is sick, all the ground beef can be contaminated. While quickly cooking the outside of a steak can kill surface germs, undercooked ground beef and other meats are still dangerous. Cooking meat all the way through is super important.

Fishes

Some fish can cause specific kinds of food poisoning. Ciguatera poisoning happens when you eat fish that ate poisonous algae, like grouper, sea bass, and red snapper. Cooking doesn't get rid of these poisons. Scombroid poisoning can happen if fish like tuna, sardines, and mahi-mahi aren't stored correctly, which lets bacteria make poisons. Cooking doesn't help with this either. It's important for restaurants to get their fish from good places and keep it stored at the right temperature.

Oyster

Oysters filter water, which means they can collect bacteria and viruses. A big risk is vibriosis, which is caused by Vibrio bacteria that live in warm ocean water where oysters grow. Eating raw or undercooked oysters is very risky. These bacteria can cause serious sickness, and sometimes even infections in the blood. Cooking oysters completely to at least 145 degrees Fahrenheit makes them much safer. So, cooked oysters are a better choice.

Leafy Greens

Greens like lettuce and spinach can get contaminated with bacteria from things like dirty water, animal poop, and not handling them correctly. Even washing them might not get rid of all the germs, especially if they're inside the leaves. Bacteria can grow fast on greens that are wilted or slimy. Restaurants need to get their greens from good farms, wash them really well, and store them correctly. Choosing fresh, crispy greens helps reduce the risk.

Steer clear of certain food items in buffets

Buffets have a higher chance of food poisoning for a few reasons. Many people use the same serving spoons, which spreads germs. Food can sit out for too long at the wrong temperature, letting bacteria grow. Also, people might cough or sneeze near the food. Common germs at buffets include bacteria like E. coli, Salmonella, and Listeria, and viruses like norovirus. Restaurants need to check food temperatures, change serving spoons often, and make sure everyone is washing their hands.

Heart diseases are one of the leading causes of death globally, yet it is not the biggest cause of concern for people. It is not just an unhealthy lifestyle that can push you to cardiovascular diseases. Sometimes when your body lacks important components, it can tip your heart health sideways.

Unexpected things like too much stress, lack of vitamin D, as well as too much vitamin B (according to some studies) can increase your risk of heart diseases. However, a surprising deficiency that can increase your risk of heart diseases is B12. However, how is a vitamin, whose role is to support nerve and brain function, responsible for your heart health?

How Does B12 Vitamin Affect Heart Health?

Another function of vitamin is forming healthy red blood vessels and DNA. While vitamin B12 is crucial for our health, but it hasn't been clear how a person's B12 levels relate to their risk of death. To understand this better, a study published in the 2024 Archives of Gerontology and Geriatrics, conducted a comprehensive review and analysis of existing studies to find out if there's a link between B12 levels and the risk of dying from all causes, heart disease, or cancer. What they found was that

• People with very high B12 levels (over 600 pmol/L) had a 50% higher risk of death from any cause and more than double the risk of death from heart disease.
• Even moderately high levels (400-600 pmol/L) were linked to a 34% higher risk of death from any cause.

They analyzed 22 studies that included a total of 92,346 people. The results showed a clear pattern:

• For every increase of 100 pmol/L in serum vitamin B12, there was a 4% higher risk of death from any cause in the general population.
• This risk was even higher for older adults, who had a 6% higher risk of death for the same increase in B12 levels.
• The connection was a straight, linear trend, meaning the risk steadily increased as B12 levels went up.

Can A Lack Of Vitamin B12 Also Cause Heart Diseases?

To find this a 2023 study published in the BMC, looked at vitamin B12 (B12), a marker for B12 deficiency called methylmalonic acid (MMA), and the risk of death has been unclear, especially for people with coronary heart disease (CHD). This study aimed to explore how MMA and B12—from blood levels, diet, or supplements—are connected to the risk of death from any cause and from cardiovascular issues in adults with CHD.

Researchers used data from a major US health survey to conduct this study. They included 1,755 adults who already had coronary heart disease (CHD) and whose levels of B12 and a related marker called MMA were measured. The study also looked at how much B12 the participants got from their diet. These individuals were followed for an average of nearly eight years to track how many of them passed away.

The study's key findings were about the connection between B12, MMA, and mortality:

Out of the 1,755 people in the study, 980 died during the follow-up period.

The study found no significant link between a person's B12 levels (from blood, diet, or supplements) and their risk of death.

In contrast, people with the highest levels of MMA had a 70% higher risk of death from any cause and double the risk of death from cardiovascular problems compared to those with the lowest MMA levels.

Interestingly, the risk of death from high MMA levels was even greater for participants who had a sufficient amount of B12 in their blood. In fact, CHD patients with high levels of both MMA and B12 had twice the risk of death compared to those with lower levels of both.

The study suggests that for patients with coronary heart disease, high levels of MMA are strongly linked to an increased risk of death, especially from cardiovascular causes. This was true even when their blood and dietary B12 levels were normal. This "paradox" may indicate that the body's ability to properly use vitamin B12 is what's important, not just the amount present in the blood.

Conclusion

Both studies and many experts agree that lack of vitamin B12 is an alarming factor for your heart health, however too much of it is also a risk variable. Before you make changes to your diet, whether to increase or decrease your vitamin B12 intake, make sure you speak to your healthcare professional to get a better idea of how much of it do you need.

When someone close to you tests positive for COVID-19, it’s natural to feel an immediate sense of urgency. The question that often follows is simple but critical: how long should you wait before getting tested? Testing too soon can give you false reassurance, while delaying too long risks spreading the virus to others. The answer lies in understanding the incubation period, the type of test you use, and the circumstances of your exposure.

COVID-19 doesn’t reveal itself instantly. It takes some time for the virus to reproduce in your body until it can be detected by tests to the level that it is present. That window is called the incubation period, and it is usually 2 to 14 days, with infections usually appearing on days 3 to 7. Waiting too long to test results in a false-negative reading because viral load isn't adequate yet. That is why professionals call for waiting for the appropriate moment before swabbing.

When To Test For COVID If You Have Symptoms?

If you get symptoms like fever, cough, tiredness, stuffiness, or loss of smell and taste—you need to test immediately. A positive antigen test is most often accurate, but a negative one isn't always the end of the matter. Since rapid tests may not catch early infections, particularly within the first days, the FDA and CDC advise retesting 48 hours later if your initial test was negative but you continue to have symptoms.

When to Test for COVID if You Do Not Have Symptoms?

For people without symptoms but with known exposure, the CDC advises testing on Day 5 after exposure. Counting starts on the day of exposure, which is considered Day 0. By Day 5, the virus is typically detectable in most individuals. Testing earlier may be useful if you’re planning to be around vulnerable populations, but it’s important to confirm results later in the incubation period with a follow-up test.

Types of Tests for COVID-19 and Accuracy After Exposure

Rapid Antigen Tests

• Speed: 15–30 minutes.
• Advantages: Suitable for rapid decisions and testing at home.
• Drawbacks: Less sensitive, particularly in the initial periods of infection or among asymptomatic individuals.
• Optimal Use: Day 5 or later since exposure; retest after 48 hours if negative.

PCR Tests

• Speed: Results usually within 1–3 days.
• Advantages: The gold standard because highly sensitive, able to identify even traces of the virus.
• Limitations: Has to be processed in the lab, longer turnaround.
• Best Use: Day 5 after contact for best accuracy.

Antibody Tests

• Speed: Variable, but not useful immediately.
• Strengths: Can identify past infection, not current.
• Limitations: Antibodies typically show up 1–3 weeks after infection.
• Best Use: To ascertain past exposure, not to test right after contact.

Why Testing Too Early Can Give Misleading Results?

Testing within 1–2 days of exposure rarely provides accurate results. At this stage, the virus is still incubating and your immune system hasn’t produced a detectable viral load. A negative result during this period can create a false sense of security, potentially leading to unintentional spread. Waiting until Day 5, unless symptoms appear earlier significantly improves accuracy.

COVID Testing Timeline Guideline

Day 0: Exposure occurs. Begin monitoring for symptoms.

Days 1–3: Remain vigilant. Avoid social contact, but delay testing unless symptoms occur.

Day 5: Test with PCR or an antigen test. If you use an antigen test and it comes back negative, retest in 48 hours.

Day 6–7: If you received a negative test result but are still worried—or must see someone high-risk—opt for a second test.

What to Do if You Test Positive?

A positive test result indicates you should self-isolate right away, notify close contacts, and adhere to public health advice. Most individuals with mild signs or symptoms can recover at home, but individuals with high-risk conditions—e.g., chronic illness, compromised immunity, or advanced age—should see a health care provider for potential antiviral treatment.

Isolation is usually 5 days from onset of symptoms or positive test (in case of being asymptomatic), but at least 10 days of masking around other people is recommended.

What if You Test Negative?

A negative test is not always conclusive. Taken too early, or if you don't have symptoms, the virus may not be visible yet. Keep on masking, watching for symptoms, and retesting as needed. If you have a subsequent onset of symptoms after a negative test, consider the infection to be possible and retest soon.

Where to Get Tested for COVID?

Testing for COVID-19 is widely available in various settings to accommodate a variety of needs. Home rapid tests, found at pharmacies and drugstores, are convenient and provide fast results, but a follow-up test is suggested if the test is negative but symptoms are still present. Healthcare clinics and pharmacies sell antigen and PCR tests, and some have appointments. Free or low-cost testing can be found at community clinics and public health clinics, especially in outbreak situations. For patients with respiratory symptoms, most clinics ask that they pre-call to reduce waiting room exposure, and telemedicine consultations are becoming more widespread throughout many areas.

Even in 2025, with better treatments and vaccines, testing is important. It catches infections early, informs isolation and treatment decisions, and safeguards at-risk populations. The CDC insists repeatedly that prompt testing—particularly following confirmed exposure—is among the best measures to slow spread.

If you’ve been exposed to COVID-19, resist the urge to test right away. Instead, monitor for symptoms and plan to test around Day 5 post-exposure. Use rapid antigen tests for quick answers, but rely on PCR tests for the most accurate results. Regardless of your test outcome, continue practicing precautions, especially around high-risk groups. Testing at the right time doesn’t just protect you—it protects your community.

Until a few years ago, a cancer diagnosis was seen as a death sentence, the simple phrase was enough to discourage people. However, with modern medicine, people have a fighting chance; they can now focus on their health and have the hope that they’ll recover. But it is not all positive.

In recent years we have seen an alarming rise in cancer diagnoses. While one likely explanation for this is that more people are aware and getting diagnosed earlier, studies have shown lifestyle choices, declining food quality and environmental factors are also to be blamed.

Now scientists have also found a gender disparity, however this difference has come as a shock to some.

A new study published in JAMA Network has uncovered a surprising trend in India: even though more women are diagnosed with cancer than men, a higher percentage of men die from the disease. This is what's known as a paradox.

Who Is Affected More By Cancer Deaths: Men Or Women?

Between 2015 and 2019, India saw more than 700,000 cancer cases.

• Women made up 51.1% of these cases.
• Men accounted for 48.9%.

Despite women having a slightly higher number of cases, the death rate tells a different story:

• 55% of all cancer deaths were among men.
• 45% were among women.

Looking ahead to 2024, the trends are similar. The estimated number of new cancer cases for women (781,277) is slightly more than for men (780,000). The crude incidence rate (CIR)—which is the number of new cases per 100,000 people—is also higher for women (113.3) than for men (107.4).

The study, which gathered data from 43 cancer registries across the country, also identified the most common types of cancer for each gender. For women, the most frequent cancers were breast, cervical, and ovarian. For men, they were oral, lung, and prostate.

Does Geography Play A Role In Cancer Cases?

that cancer cases are not spread out evenly across India—some areas have much higher rates than others. The highest rates were found in a specific region of the country.

The top five places with the highest rates of cancer were mostly in northeast India. The city of Aizawl in Mizoram had the highest rates for both men and women. Other high-risk areas included Kamrup Urban, Papumpare, and East Kasi Hills. The only exception on this list was Hyderabad.

Just how big is this difference? Another study from 2023 found that cancer rates in Aizawl were seven times higher for men and four times higher for women compared to regions in Maharashtra like Osmanabad and Beed.

Why Cancer Rates Are Higher for Women

So, why do more women in India get cancer? Experts point to several factors:

• Changes in diet, lack of physical activity, and the use of tobacco and alcohol are all risk factors.
• The rise in hormone-related cancers, such as breast and ovarian cancer, may be linked to people being more exposed to pollutants in the air and harmful chemicals in cosmetics and processed foods.
• Things like having children later in life can also increase a woman's risk.
• Financial and social barriers can play a role in a woman's health.

Why Is There A Gender Disparity Among Cancer Survivors?

Even though more women get cancer, more men die from it. This is likely because the most common cancers found in women—like breast and cervical cancers—are very treatable if they are found early. For example, the American Cancer Society states that the five-year survival rate for breast cancer is over 90% when it's diagnosed in the early stages.

However, a new and worrying trend is emerging. A study from March 2025 found that over the past decade, cancer-related deaths have been increasing more quickly among women than men. This trend is expected to continue. Experts suggest this could be because women face challenges like getting the wrong diagnosis, having limited access to good quality healthcare, and other financial and social barriers.
