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.

Malaria infected an estimated 282 million people and caused about 6,10,000 deaths worldwide in 2024, according to the World Health Organization’s (WHO) latest World Malaria Report. The report placed strong emphasis on drug resistance, warning that it remains one of the biggest threats to global elimination goals.

WHO-recommended vaccines helped prevent roughly 170 million cases and one million deaths last year, which is about nine million more than the year before. Around 95 per cent of malaria deaths occurred in the African Region, with children under five forming the largest share.

Within the WHO South-East Asia Region, India represented 73.3 per cent of all malaria cases and 88.7 per cent of all malaria-related deaths. The report also underscored that the world is nowhere close to meeting the targets set under the Global Technical Strategy for malaria 2016–2030.

However, a group of University of Nottingham researchers have now found a key protein that is an enticing target for new antimalarial interventions. The study looked at a protein called Aurora-related kinase 1 (ARK1), which plays an important role in the parasite’s unusual cell division.

ARK1 helps control the parasite’s mitosis (cell division) and organizes a structure called the spindle, which separates genetic material so new parasites can form.

Scientists turned off the ARK1 gene using genetic engineering techniques to see what would happen. Without ARK1, the parasites could not form proper spindles and failed to reproduce, suggesting the protein could be a weak spot that future malaria treatment.

"What makes this discovery so exciting is that the malaria parasite's 'Aurora' complex is very different from the version found in human cells," senior author Rita Tewari said.

What Are Anopheles Stephensi Mosquitoes?

Anopheles stephensi is a malaria-transmitting mosquito originally found in South Asia. Unlike many other malaria vectors, it thrives in cities and breeds in man-made water sources such as storage tanks, containers, and discarded tyres. It can carry both Plasmodium falciparum and P. vivax parasites.

In recent years, this mosquito has spread into several African countries, where it adapts easily and shows resistance to multiple insecticides. This expansion has increased the threat of urban malaria outbreaks, as highlighted by the World Health Organization.

At present, Anopheles stephensi has been detected in nine African countries and is proving difficult to control due to widespread insecticide resistance.

Malaria Vaccines

The report noted that WHO approved the world’s first malaria vaccines in 2021, and 24 countries have now added them to their regular immunisation schedules. Dr Tedros Adhanom Ghebreyesus, WHO Director-General, said that new preventive tools provide reason for optimism, but many obstacles remain.

He pointed out the rise in cases and deaths, the pressure from drug resistance, and the impact of reduced funding. These factors could undermine the progress achieved over the last twenty years.

Men planning to conceive should practise caution while consuming antioxidant supplements, as excessive intake may affect sperm and early craniofacial development in babies, a Frontiers in Cell and Developmental Biology study shows.

Antioxidants are often promoted as powerful supplements that can help protect the body from chronic conditions, including cancer, chronic obstructive pulmonary disease and dementia.

However, researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) found that consuming high levels of the antioxidant compounds N-acetyl-L-cysteine (NAC) and selenium (Se) can alter skull and facial shape in female children, even though the treated fathers did not exhibit obvious health problems.

Dr Michael Golding, a professor in the VMBS’ Department of Veterinary Physiology and Pharmacology, whose research team made the discovery said: "We know alcohol causes oxidative stress and we were looking to push back on it by adding a supplement known to lower oxidative stress.

"When we realized that offspring born to males that had only been given NAC were displaying skull and facial differences, it was a surprise because this molecule is universally thought to be good.

“When we sat down to think it through, we realized that it makes sense — you take a multivitamin to ensure that you’re in balance, but if the thing that you’re taking to ensure you’re in balance is unbalanced (the dose of antioxidants is too high), then you’re not doing a good thing.

“Sperm health is another performance metric; it’s just not one that we think about in everyday life. If you’re taking a high-dose antioxidant, you could be diminishing your reproductive fitness, and part of the journey toward the bad outcome is going to be the effects on the offspring.”

What Are Antioxidants?

Antioxidants are important because they protect the fundamental structure of the human body, cells. They safeguard an individual's DNA and proteins from the damage caused by free radicals.

Research has shown that a diet high in antioxidants may help individuals prevent chronic diseases and mental health issues. But on the contrary, having too many antioxidants in your body could confuse your cells' responses, leading to more damage than intented.

How Do Antioxidants Protect Your Body?

Antioxidants basically neutralize free radicals in the body. These free radicals are extra atoms that are produced during the body's internal processes and also by some external factors.

Overproduction of these free radicals, during the process of oxidation in the human body, damages cell membranes and other structures, including cellular proteins, lipids and DNA. Oxidation can be exacerbated by stress, smoking, alcohol, sunlight and pollution.

In the long run, they can lead to diseases such as cancer and heart diseases. It is pertinent to note that the brain is prone to oxidative stress due to its high metabolic activity. Here, the role of antioxidants becomes particularly important as they fight oxidative stress which could otherwise lead to stroke, traumatic brain injury or neurodegenerative diseases like Alzheimer's.

If you take large amounts of antioxidants, then it could hamper the cell's defence mechanisms and normal signalling. Different types of antioxidants also have different properties, so they may not be interchangeable. Therefore, health experts advise people to be mindful of the amount of antioxidant-rich food they are including in your diet. Notably, studies have found that antioxidant supplements have a lower impact such as natural food items.

Here Are Top 10 Antioxidant Rich Food:

• Blueberries: Packed with anthocyanins, which help fight oxidative stress and inflammation.
• Dark Chocolate (70 percent cacao or higher): Rich in flavonoids, known for their heart health and antioxidant properties.
• Spinach: Contains vitamins C and E, flavonoids, and carotenoids, all potent antioxidants.
• Nuts (especially almonds and walnuts): High in vitamin E and other antioxidant compounds that protect cells from damage.
• Green Tea: Loaded with polyphenols, particularly catechins, which are powerful antioxidants.
• Kale: Full of vitamins A, C, and K, along with flavonoids, which support immune function.
• Tomatoes: Rich in lycopene, a carotenoid antioxidant that supports skin health and may reduce the risk of certain cancers.
• Carrots: High in beta-carotene, which is converted to vitamin A and offers strong antioxidant benefits.
• Avocados: Packed with healthy fats, vitamin E, and carotenoids, helping to reduce oxidative stress.
• Pomegranates: Contain punicalagins and anthocyanins, powerful antioxidants that may help lower inflammation and improve heart health.

A simple biomarker blood test can now detect dementia in women 25 years before symptoms appear, a JAMA study suggests.

Researchers from the University of California San Diego have found a protein in the blood called plasma phosphorylated tau 217 (p-tau217), a protein linked to the brain changes seen in Alzheimer’s disease.

The researchers found a strong association between higher levels of p-tau217 in the blood and a higher chance of developing both mild cognitive impairment (MCI) and dementia, a key contributer in the developemnt of Alzheimer’s.

Neuroscientist Linda McEvoy, from the Kaiser Permanente Washington Health Research Institute: "Blood-based biomarkers like p-tau217 are especially promising because they are far less invasive and potentially more accessible than brain imaging or spinal fluid tests.

"This is important for accelerating research into the factors that affect risk of dementia and for evaluating strategies that may reduce risk."

The connection between higher p-tau217 and dementia was stronger in women over 70, the researchers also found, and in those carrying the APOE ε4 gene that has been linked to Alzheimer's disease in the past.

What Is Dementia?

Dementia is an umbrella term used to describe a significant decline in mental function that is serious enough to affect everyday life. It commonly impacts memory, thinking, and reasoning skills.

Dementia itself is not a single disease but a collection of symptoms caused by underlying conditions such as Alzheimer’s disease or vascular dementia.

Common signs include memory problems, confusion, difficulty finding words, changes in mood or behaviour and trouble completing familiar tasks.

These symptoms usually worsen over time and are not considered a normal part of ageing. Although there is no cure, treatment options can help manage symptoms, and early diagnosis plays an important role in care planning.

Alzheimer’s Disease: The Leading Cause of Dementia

Alzheimer's disease is one of the most common forms of dementia and mostly affects adults over the age of 65.

About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.

Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure for this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.
