Food safety concerns are up and front in the country again, with recent recalls hitting the retail shelves of organically grown carrots, slivered onions, and liverwurst sold by brands that include Boar's Head and McDonald's. Some question whether these high-profile incidents herald deeper challenges for the U.S. food safety system. But experts caution not to panic-and they point to improvements in detection and response as reasons why recall news is so prominent.

While the increase in recalls may alarm, it could be a sign that foodborne illnesses are increasingly being found and handled faster rather than a sign of a failing system. Rutgers University food science department chair Don Schaffner said the tools of whole genome sequencing now allow health officials to pinpoint and track an outbreak with precision in a way that simply wasn't possible before. That quick identification allows public health officials to move fast-to interview victims, trace sources of contamination-when a problem surfaces.

Public health expert Craig Hedberg at the University of Minnesota comments that many of these outbreaks would have otherwise gone undetected. Advanced surveillance and laboratory analysis allow small clusters of illness to be linked directly to a source, so recalls can be issued and public advisories can be released on time.

"When these outbreaks are identified and investigated, steps can be taken to protect public health," Hedberg says. "That's why there's a strong interest in keeping the public informed." Food Recalls Are on the Rise, but is it Necessarily Bad News?

Outbreaks of foodborne illnesses are by nature hard to predict. According to Schaffner, the recent clustering of high-profile incidents could simply be coincidental and not indicative of a systemic problem.

The eating habits and food production also make their contribution to the changes in food safety. Food safety expert Darin Detwiler from Northeastern University points out that the more people choose ready meals and restaurant meals, the greater the complexity of food supply chains becomes. Ingredients travel further, go through multiple processing steps, and change hands several times before consumers get them, and the possibilities of contamination increase.

Is the patchwork approach to blame for food safety regulation?

The U.S. food safety system operates on an intricate network of agencies, each covering different aspects of regulation; the USDA focuses on meat and poultry, while the FDA monitors most other food items, including overseeing recalls. In outbreak situations, the CDC works in conjunction with local health departments to investigate and contain the spread of illnesses.

Despite this overall framework, gaps in food safety can occur. Civil litigation serves as a safety net when food-borne diseases slip through regulatory cracks. According to Timothy Lytton, a professor at Georgia State College of Law, liability suits compel food producers to adhere to strict safety standards. Insurance companies, which cover potential risks, will also help through counseling and the promotion of incentives to minimize the risk involved.

Protecting Yourself from Foodborne Illness

As regulatory agencies and companies continue to work on the safety of food, it also remains crucially important for consumers to be proactive at home. Here are some steps:

1. Monitoring Food Recalls: Stay on top of recalls through FDA updates and remove affected products from your kitchen.

2. Hygiene and Its Practices: Be sure to wash your hands thoroughly with soap and water before touching and after handling food.

3. Wash Fresh Fruits and Vegetables: Even those that are pre-washed should still be washed under running water to remove unseen bacteria, especially from crevices or wounded areas.

4. Prevent Cross-Contamination: Separate cutting boards and utensils must be used for raw meat and fresh fruits and vegetables.

5. Cook Food Properly: Meat, Poultry, and Seafood must be cooked to a safe internal temperature to kill harmful microorganisms.

While food recalls can be scary, they are also a reflection of advances in monitoring and responding to food safety. For instance, due to advances in technology and surveillance, outbreaks may now be detected and contained faster than ever before, thus mitigating the potential risks to public health.

Meanwhile, the increased complexity of the food industry underscores that vigilance needs to be taken at every step of the supply chain. With knowledge, safe food-handling practices, consumers can participate actively in protecting themselves and their families from foodborne diseases.

In the end, the increasing profile of food recalls is as much a story of solutions as of problems — reminding one and all that protecting our food supply is a shared responsibility that involves regulators, producers, and consumers.

There is a reason why when we think about coffee, we only see ‘caffeine’ in big, bold letters. It helps up wake up, stay energetic, alert, sharpens our attention and helps us fight the midday grogginess at work. So, little attention has been paid to other components of coffee.

But new research suggests some of coffee’s effects on the brain may have little to do with caffeine.

A study published in Nature Communications found that both caffeinated and decaffeinated coffee were linked to changes in the gut microbiome, mood and stress. But improvements in learning and memory were seen specifically among people who drank decaffeinated coffee.

The findings suggest that coffee’s effects on the brain could involve its many other compounds and the gut-brain connection, rather than caffeine alone.

How Was The Study Conducted

Researchers from APC Microbiome Ireland at University College Cork studied 62 people. Thirty-one were regular coffee drinkers, while 31 did not normally drink coffee.

The regular coffee drinkers first stopped consuming coffee for two weeks. Researchers then collected stool and urine samples and monitored their mood, stress, cognition and other measures.

Coffee was subsequently reintroduced, with participants receiving either caffeinated or decaffeinated coffee for three weeks. The researchers found that both forms of coffee were associated with changes in gut bacteria and metabolites. But when it came to cognitive effects, there was a striking finding.

Decaffeinated Coffee Improved Memory

Participants who drank decaffeinated coffee showed significant improvements in learning and memory. For example, they made fewer errors on a test examining learning and memory. They also showed improvements in episodic memory, which involves remembering information and experiences.

The caffeinated group did not show the same results. This helped researchers find out that the non-caffeine components of coffee may have some positive cognitive effects.

But the researchers also acknowledge that some of the improvement could have happened due to participants becoming more familiar with the tests over time.

Decaf Coffee's Effect On Brain

Coffee contains thousands of chemical compounds, including polyphenols. These compounds can interact with gut microbes and influence the production of metabolites, which can then affect the body and brain. This is where the gut-brain axis comes into the picture.

The gut and brain are in constant communication through several processes involving the nervous system, immune system, hormones and chemicals produced by gut bacteria.

The study found that coffee consumption altered the composition and activity of gut microbes and changed certain metabolites. Some bacteria, including Eggerthella species and Cryptobacterium curtum, were more found in more quantity among coffee drinkers.

Researchers believe these microbial changes could help explain some of coffee’s effects on mood and cognition.

Effects Of Caffeinated Coffee

Participants drinking caffeinated coffee experienced reduced anxiety and other psychological effects, while some measures of attention and cognitive performance also improved.

Both caffeinated and decaffeinated coffee showed lower signs of stress, depression and impulsivity.

So the study does not suggest that decaf is universally better for the brain. Instead, it shows that different components of coffee may produce different effects.

It also adds another layer to the increasingly complicated story of coffee and health. Coffee may be more than a delivery system for caffeine. Its polyphenols and other compounds may interact with gut bacteria, influencing metabolism, inflammation, mood and brain function.

Red Bull got relief after Delhi High Court overturned a Food Safety and Standards Authority of India (FSSAI) order that instructed the Austrian beverage giant to drop its ‘energy drink’ label. In a recent ruling, the court made its decision after it found that the Indian food regulator did not give sufficient time to the company to present its case.

While the legal fight between the food regulator and the billion-dollar beverage giant boils down to just two words on a can, the health question is much bigger: What does drinking an energy drink like Red Bull actually do to the body?

FSSAI Vs Red Bull

FSSAI had said India does not have a notified food standard specifically defining an “energy drink”, objecting to brands like Red Bull making claims like boosting energy or enhancing focus.

The regulator's concerns also included linked to what these beverages actually contain, particularly excessive caffeine, sugar, and other controversial ingredients like taurine.

The biggest concern that the lawsuit is built upon is what causes the sudden surge of ‘energy’ after someone consumes this drink. Is it giving your body useful energy?

Red Bull’s Ingredients And What It Does To Your Body

Caffeine

One of the main ingredients responsible for the immediate feeling of energy alertness is caffeine. Caffeine stimulates the central nervous system, making you feel more awake and less tired. But that boost does not mean the drink is providing the body with sustained energy in the nutritional sense.

Depending on the product, energy drinks can also contain substantial amounts of added sugar, which adds calories but does not make the drink healthier.

The caffeine content of energy drinks varies considerably. The US FDA notes that energy drinks can contain roughly 41 to 246 mg of caffeine per 12 fluid ounces, depending on the product.

The energy boost claim may comes from the caffeine content, which is what consumers should be mindful about. Too much caffeine can lead to faster heartbeat, palpitations, increased blood pressure, anxiety, jitters, headaches, nausea and sleep disruption. For most healthy adults, the FDA cites 400 mg of caffeine a day.

Energy drinks can also temporarily increase blood pressure and cardiovascular load. A 2024 review and meta-analysis of randomised trials found that energy drinks acutely increased systolic and diastolic blood pressure in healthy adults.

Excess caffeine in young people can cause palpitations, increased heart rate and blood pressure, anxiety, sleep problems and digestive symptoms. Therefore, the FDA and medical experts advise against energy drinks for children and teenagers.

This is also why energy drinks have attracted regulatory restrictions worldwide. England, for example, plans to prohibit their sale to under-16s from April next year.

Sugar

The sugar content is another reason to be careful about how often you drink energy drinks. Regular and frequent consumption of high amounts of added sugar, through liquid calories like energy drinks, can increase overall calorie intake and contribute to weight gain and obesity.

Over time, excess sugar intake is also linked with a higher risk of metabolic problems like type 2 diabetes and fatty liver disease. For people who regularly consume these energy drinks, the concern is therefore not just the caffeine, but also how much added sugar they are consuming with each can.

Taurine

HealthAndMe previously reported that taurine may help fuel the growth of certain leukaemia cells. The research raised questions about taurine's role in blood cancer. The research was about the behaviour of cancer cells and does not establish that taurine-laced energy drinks cause blood cancer in humans.

Taurine occurs naturally in protein-rich foods like meat and fish and is also produced in the human body. Known for its function of maintaining fluid balance, cardiovascular support, and electrolyte regulation, taurine has been touted for years as a "health-enhancing" supplement. Taurine is also added to energy drinks for its claimed brain-boosting and anti-inflammatory effects and is marketed as a means to enhance mental concentration and physical output.

A study by University of Rochester's Wilmot Cancer Institute revealed how leukemia cancer cells hijack taurine as an energy source. Specifically, the cancer cells take in taurine to fuel glycolysis—a biological process that allows them to produce energy and proliferate at a fast rate.

The bottomline is that the Delhi High Court's ruling does not mean that Red Bull has been declared healthy. It addresses whether FSSAI followed the correct procedure when restricting the “energy drink” label. So even though Red Bull can be marketed and sold as an “energy drink”, it cannot be automatically considered healthy.

Eating more ultra-processed food (UPF) has been associated with a higher risk of several chronic health conditions, including cardiovascular disease, cancer, metabolic disorders and high blood pressure.

Yet another large review of studies involving about 9 million participants showed that every additional 100 grams of UPF consumed per day was associated with a 14% higher risk of cardiovascular events and an 11% higher risk of high blood pressure.

This is concerning because cardiovascular diseases (CVDs) are the world’s leading cause of death. In 2022, an estimated 19.8 million people died from CVDs, accounting for about 32% of all deaths globally. Heart attacks and strokes caused 85% of these deaths, as per data from the WHO.

Uncontrolled blood pressure is also worrying as it is a leading cause of heart attack, stroke, chronic kidney disease, and dementia. An estimated 1.4 billion people lived with hypertension in 2024, yet just over one in five have it under control either through medication or addressing modifiable health risks.

What Did The Study Find?

The findings, published in the open-access journal Family Medicine and Community Health, were based on 51 prospective cohort studies involving 8,819,894 participants across the Americas, Europe, Asia and Oceania.

The researchers found that people with higher UPF consumption had greater risks of several health problems:

• Cardiovascular events: 24% higher risk
• Cancer: 12% higher risk
• Overweight or obesity: 23% higher risk
• Metabolic syndrome or diabetes: 24% higher risk
• Depression or anxiety: 27% higher risk
• Digestive diseases: 31% higher risk
• High blood pressure: 11% higher risk
• Death from any cause: 18% higher risk

The researchers also examined the association with every additional 100 grams of UPF consumed per day. This was associated with:

• 14% higher risk of cardiovascular events
• 4% higher risk of cancer
• 3% higher risk of death from any cause
• 2% higher risk of metabolic syndrome or diabetes

The studies included participants aged 23 to 77 years, with follow-up periods ranging from two to 32 years.

How UPF Affects Heart Health?

The researchers said emerging evidence suggests that exposure to multiple additives in UPFs may have combined effects on health.

Some compounds that can form during food processing, including acrylamide and acrolein, have been associated with cardiovascular disease.

Laboratory research also suggests that the altered physical structure of UPFs may affect the gut microbiome and contribute to inflammation and insulin resistance.

However, the researchers noted that these mechanisms are still being investigated.

“Given that UPF-related chronic diseases often cluster as multi-morbidity, reducing consumption of UPFs and replacing them with minimally processed alternatives may be relevant for chronic disease prevention and primary care management,” the Duke-NUS Medical School researchers said.

What Are Ultra-Processed Foods?

Ultra-processed foods are industrially manufactured products that typically contain ingredients and additives not commonly used in home cooking.

They can include:

• Sugary drinks
• Processed meats
• Packaged snacks and chips
• Candy and confectionery
• Baked goods
• Refined grain products
• Ready-to-eat or ready-to-heat meals

Many UPFs are high in added sugar, sodium, and refined carbohydrates and may contain additives such as emulsifiers, sweeteners, preservatives, colorants and flavor enhancers.

Limit ultra-processed foods to lower risk of heart disease, say experts. Replacing some ultra-processed foods with minimally processed alternatives may therefore be one dietary approach to consider as part of broader chronic disease prevention.
