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.

Obesity during the 20s and 30s can fuel the risk of many lifestyle disorders like type 2 diabetes, cardiovascular diseases, metabolic syndrome, non-alcoholic fatty liver disease, sleep apnea and many others.

But according to a large study published in Annals of Internal Medicine, obesity could also increase the risk of developing cancer before midlife. The study identified higher chances of thyroid, endometrial and ovarian cancers.

How Was The Study Conducted?

Researchers examined health records of 6,313,338 adults in South Korea, aged between 20 to 39 years, who had no previous history of cancer.

Participants were followed for an average of 11.2 years to study the relationship between body weight and cancer risk.

During the follow-up period, 151,893 cancer cases were recorded. The findings showed that cancer risk increased in people with higher body mass index (BMI).

The researchers found that the 10-year total incidence of cancer was 1.84% among people with normal body weight. This increased to 2.24% among those with class I obesity and 2.62% among those with class II obesity.

In other words, the 10-year cancer incidence was approximately 0.78 percentage points higher among people with class II obesity than among those with normal weight.

The researchers also found that people with abdominal obesity were at higher cancer risk than those who didn’t have.

Among people with class I obesity, the 10-year cancer incidence was 2.45% in those with abdominal obesity, compared with 2.13% in those without it.

“Because abdominal obesity may be an important indicator for distinguishing cancer risk, it is important to manage waist circumference along with weight from a young age,” the authors wrote.

Three Cancers Linked To Early Adulthood Obesity

The study identified particularly strong associations between obesity and cancers involving the thyroid and female reproductive system.

Thyroid cancer: Excess body weight has previously been linked with changes in metabolic and hormonal changes that may affect thyroid cancer development.

Endometrial cancer: Obesity can increase oestrogen levels because fat tissue produces this hormone. Prolonged exposure to excess oestrogen can stimulate the growth of the uterine lining and increase the risk of endometrial cancer.

Ovarian cancer: The relationship between obesity and ovarian cancer is complex and may involve inflammation, insulin resistance and hormonal changes.

Obesity & Cancer Risk

Obesity causes several biological changes that may contribute to cancer development. One of them is chronic inflammation.

Excess fat tissue can fuel inflammation that may create an favourable environment for abnormal cell growth.

Obesity can also lead to insulin resistance, in which the body’s cells respond less effectively to insulin. This can cause higher insulin levels, which may fuel cell growth and proliferation.

Hormonal changes are also a factor. Fat tissue produces oestrogen, and higher levels of this hormone have been linked with cancers like endometrial and ovarian.

The study authors wrote, "Some cancers have recently become more common even among younger people, and this study confirmed that obesity in young adults is significantly associated with the development of these cancers."

Scientists have discovered a previously unknown mechanism that could explain why high cholesterol diet makes it challenging for the liver to remove bad cholesterol from the bloodstream. Researchers have also identified an experimental drug that blocks this process, offering a new method for treating high cholesterol.

The findings are published in the journal Nature by researchers from the University of California San Diego School of Medicine. Their experiments showed that blocking a specific enzyme called cathepsin A (CTSA) helped retain the liver's ability to clear low-density lipoprotein (LDL), commonly known as bad cholesterol.

In mice, inhibiting this enzyme stabilised LDL receptors in liver cells, reducing LDL cholesterol.

"We've known for a long time that a high-cholesterol diet reduces the liver's ability to clear cholesterol from the blood, but we didn't fully understand why," said senior author Alan Saltiel, professor of medicine at UC San Diego School of Medicine. "This new discovery explains a critical piece of that puzzle."

More About The Experiment

The liver plays a key role in regulating cholesterol levels. It uses LDL receptors located on the surface of liver cells to capture LDL cholesterol from the bloodstream.

When fewer of these receptors are available, the liver becomes less efficient at removing LDL cholesterol, allowing it to increase in the bloodstream. The researchers discovered that consuming high amounts of dietary cholesterol activates a protein called Ral. This increases the activity of CTSA, an enzyme that breaks down LDL receptors.

As these receptors are lost, the liver's ability to clear bad cholesterol declines. When researchers blocked CTSA using a small molecule inhibitor, LDL receptors became more stable and LDL cholesterol levels decreased dramatically in mice.

Experimental Drug That Can Help Lower Cholesterol

The discovery has sparked interest as researchers have identified an experimental drug that targets CTSA. The drug was originally developed as a possible treatment option for heart failure. Although its development for that purpose was discontinued for other reasons, it had already completed a Phase 1 clinical trial, which evaluated its safety in humans.

This previous test could help researchers move towards studying its ability as a cholesterol treatment. However, the drug has not yet been shown to lower LDL cholesterol in humans.

"There's still a real need for new cholesterol-lowering options, since some people can't get to safe levels even with the drugs we have now," Saltiel said.

He added, "This new pathway we discovered is completely separate from anything that existing drugs target, so it gives us a new opportunity to fill that gap."

The researchers hope to test the experimental CTSA inhibitor in a Phase 2 clinical trial to determine whether it can safely and effectively lower cholesterol in people. If successful, the approach could offer another option for people who struggle to control LDL cholesterol despite using existing treatments.

Saltiel said, "Luckily, there's an experimental drug sitting on the shelf that's already been shown to be safe in humans."

"We hope to test whether this might be effective by conducting a clinical trial -- which could potentially bring a new treatment option to patients much sooner than would have been expected."

Irritable bowel syndrome (IBS) is often characterised by digestive symptoms like abdominal pain, bloating, constipation and diarrhoea. However, the condition involves more than the digestive system.

A new review published in The Lancet explains how interactions between the gut and brain, changes in the gut microbiome, immune activity and the body's response to pain can contribute to the development of symptoms.

The review, titled Irritable bowel syndrome and related disorders of gut-brain interaction, brings focuses on biological and psychological evidence behind IBS. Researchers describe it as a disorder of gut-brain interaction, in which signals between the digestive system and the central nervous system affect gut function.

The authors also discuss chronic constipation and functional diarrhoea, which belong to the bigger group of disorders related to gut-brain interaction. These conditions may affect an estimated 20% of the global population.

What Is The Gut-Brain Connection In IBS?

The gut and brain communicate continuously through a complex network that involves the central nervous system, autonomic nervous system, enteric nervous system and hypothalamic-pituitary-adrenal (HPA) axis.

The brain can influence intestinal movement, secretion and sensitivity, while signals from the gut can affect how the brain processes pain and other sensations.

In people with IBS, this communication may become disrupted. The result can be changes in bowel movements, more sensitivity to normal digestive processes and abdominal discomfort.

The authors said, “These central and peripheral mechanisms can act in an integrated way to cause IBS symptoms, via the gut-brain axis.”

For instance, a person with IBS may experience pain or bloating even when the amount of gas or intestinal movement would not cause discomfort in someone without the condition. This is due to a condition called visceral hypersensitivity, in which the nerves supplying the digestive organs become unusually sensitive to internal sensations.

The review explains that changes in both peripheral mechanisms within the gut and central mechanisms involving the brain can contribute to symptoms.

Gut Bacteria And Inflammation May Contribute To IBS

The gut microbiome, which consists of microorganisms living in the digestive tract, is another important part of the gut-brain connection.

Changes in the composition and activity of gut bacteria may impact intestinal function, immune responses and communication with the nervous system. The review identifies the following:

• Gut infections: Gastrointestinal infections can trigger IBS symptoms in some people, even after the initial infection has subsided.
• Altered gut microbiome: Changes in intestinal bacteria may affect digestion, immune activity and gut function.
• Increased intestinal permeability: Changes in the intestinal barrier may allow substances to pass through more easily, potentially contributing to immune activation.
• Low-grade inflammation: Mild inflammation in the intestinal lining and changes in immune function may contribute to symptoms.
• Abnormal gut movement: Changes in gastrointestinal motility can cause food and waste to move through the digestive tract too quickly or too slowly.
• Visceral hypersensitivity: Increased sensitivity in the gut can make normal digestive processes feel painful.

Mental Health And IBS

Psychological health is another component of the gut-brain axis. Stress, anxiety and other psychological difficulties can influence how the brain processes pain and communicates with the digestive system.

The HPA axis, which helps regulate the body's response to stress, plays a role in this process . Changes in stress levels can affect gut movement, secretion and sensitivity.

Currently, there is no single biomarker that can diagnose IBS. Doctors assess symptoms, medical history and clinical findings, while using tests to rule out other conditions.

The review highlights that some underlying mechanisms can already be measured through approved tests and questionnaires. These include abnormal bile acid metabolism, accelerated movement of contents through the colon and psychological conditions.
