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.

High-protein diets have become increasingly popular among fitness enthusiasts and health-conscious masses.

However, a new scientific review suggests that many adults, particularly those who are sedentary, maybe consuming more protein than they actually need.

The study also shows that eating less protein rather than more may support healthier ageing by improving metabolism and reducing age-related biological changes.

Are Low Protein Diets The Key To Live Longer?

The review, published by Cell Press, studied data from more than 350 studies investigating how dietary protein affects ageing and metabolic health.

Researchers concluded that reducing overall protein intake, or restricting certain amino acids like methionine, isoleucine, and valine, activates biological pathways linked to better metabolic function, cellular maintenance, and lower inflammation.

According to the researchers, several of these benefits appear to be driven by fibroblast growth factor 21 (FGF21), a hormone that rises when protein intake falls.

Higher FGF21 levels have been associated with better insulin sensitivity, better blood sugar regulation, increased energy expenditure, and healthier ageing in experimental models.

Lead author Dr Dudley Lamming, professor at the University of Wisconsin-Madison, said the growing popularity of protein-enriched foods may not benefit everyone.

"Our review suggests that reducing protein intake, rather than calories, may provide many of the same metabolic benefits while being easier for people to follow," the research team noted, adding that protein recommendations may need to be tailored according to an individual's age and physical activity rather than using a one-size-fits-all approach.

Excessively High-Protein Diets May Increase Metabolic Burden

HealthandMe spoke to Dr. Mukesh Thakur, Director - Internal Medicine, Acute Medicine & Clinical Transformation, Sir H. N. Reliance Foundation Hospital, to find out who should and should not cut back on protein to improve longevity.

The doctor says that protein is essential for maintaining muscle mass, supporting immune function, and promoting overall health.

Dr Thakur says, "The optimal amount of protein varies depending on factors such as age, overall health status, and, most importantly, an individual's level of physical activity. For people who are largely sedentary, consuming very high amounts of protein may not offer additional health benefits."

He added that if the excess protein consumed is not utilized to build or maintain muscle through regular physical activity, it may contribute to excess calorie intake and increase metabolic stress.

He also explains, "Emerging research also suggests that chronically high protein intake, particularly from animal sources, may overstimulate biological pathways such as IGF-1 and mTOR, which have been linked to accelerated ageing in experimental studies."

To sum up, for individuals with obesity or diabetes, excessively high-protein diets can be particularly concerning, as they may increase the metabolic burden and are not necessarily associated with better health outcomes.

Conclusion

The researchers caution that the findings should not be interpreted as a recommendation for everyone to reduce protein intake.

While sedentary adults consuming excessive protein may benefit from moderation, adequate protein remains essential for older adults, athletes, pregnant women, children, and people recovering from illness or surgery to maintain muscle mass and overall health.

Today, protein has found its way into everything from coffee and cereal to chips and even water. But a new scientific review suggests that for many adults, especially those who are not physically active, consuming more protein than needed may offer little benefit and could even have pose unintended health consequences.

Published in Cell Press Blue, the review analyzed more than 350 studies on restriction of protein, aging, metabolism, and longevity across humans and animal models.

Researchers concluded that while protein remains essential in one's diet, most sedentary adults are likely consuming more than they need. It also found that bringing down excess protein intake may support healthier aging.

“It’s absolutely crystal clear that there are benefits of protein to muscle growth and exercise response of active individuals,” said Dr. Dudley Lamming, aging researcher at the University of Wisconsin-Madison and the review’s corresponding author.

“But because most people are relatively sedentary, many people are likely consuming more protein than they actually need, which probably has negative health consequences,” he added.

Can Eating Less Protein Help?

The researchers explain that eating less protein appears to activate several biological pathways that are associated to healthy aging.

One key player is fibroblast growth factor 21 (FGF21), a hormone that rises when protein intake is reduced.

Higher FGF21 levels have been associated with increased energy expenditure, better blood sugar control, lower inflammation, and healthier metabolism. Animal studies have also linked elevated FGF21 to longer lifespan.

The review also highlights specific amino acids, including methionine, isoleucine, and valine, which may influence aging-related processes when consumed in excess. Restricting these amino acids appears to alleviate cellular stress and improve metabolic health in experimental studies.

Researchers caution that the findings do not mean everyone should start eating a low-protein diet.

Protein requirements vary depending on age, activity level, health status, and life stage. Athletes, pregnant women, people recovering from illness or surgery, and many older adults often require more protein for muscle maintenance and recovery.

“Recent recommendations have encouraged people to eat more protein, but they’ve also encouraged people to exercise more,” Lamming said. “We probably need to personalize protein recommendations based not just on age, but also on how physically active people are.”

How Much Protein Do Adults Actually Need?

For healthy adults, the recommended dietary allowance is 0.8 grams of protein per kilogram of body weight daily. Although individual needs increase with regular exercise, aging, pregnancy, or certain medical conditions.

Many adults already exceed these recommendations through regular meals alone, even before adding protein supplements.

The researchers acknowledge that much of the evidence comes from animal studies, and long-term human trials are still limited. They say future research should determine exactly who benefits from lower protein intake and who needs more.

As protein-fortified products continue to flood supermarket shelves, the researchers argue that dietary advice should become more personalized rather than assuming higher protein intake benefits everyone.

Ultra-processed foods (UPFs), typically high in salt, sugar, and unhealthy fats, have long been associated with obesity, diabetes, hypertension, and other chronic diseases.

Now, new research suggests that the vast majority of foods marketed for toddlers in the US fall into this category. A study led by the University of Texas at Austin found that more than 80% of toddler foods sold in US grocery stores are ultra-processed, while nearly half fail to meet at least one nutrient standard set by the World Health Organization (WHO) for commercial foods intended for children aged 6 to 36 months.

Researchers analyzed 2,783 toddler food products sold across 21 grocery stores in Texas. Using the Nova classification system, they found that 81% of products were ultra-processed, while 49% failed to meet at least one WHO nutrient standard.

Among the products analyzed:

• 81% were classified as ultra-processed.
• 17% exceeded WHO recommendations for sugar.
• 25% exceeded recommended sodium levels.
• 11% exceeded recommended fat levels.
• 12% exceeded recommended energy density.

Products that exceeded WHO recommendations included:

• Fruit pouches (high in sugar)
• Oat bars (high in sugar and calories)
• Mac and cheese (high in sodium and fat)
• Turkey sticks (high in sodium and fat)
• Cheese puffs (high in calories)
• Peanut butter puffs (high in sodium, fat, and calories)

“Many parents may assume that products sold on the baby/toddler food aisles of their grocery stores have to meet certain nutrient standards. Our findings highlight that half of the toddler foods available in local grocery stores do not,” said Erin A. Hudson, a University of Texas at Austin graduate student and science policy fellow with the American Society for Nutrition.

Hudson urged parents "to be vigilant in checking labels and ingredients to determine the nutrient content and processing level of products for their toddlers".

Why Is This Concerning?

The toddler years are a crucial period for developing lifelong eating habits and taste preferences. Diets high in added sugars and ultra-processed foods during early childhood may increase the risk of obesity, diabetes, cardiovascular disease, and other chronic illnesses later in life.

The researchers found that ultra-processed toddler foods were significantly more likely to be high in sugar than less-processed alternatives. Excess sugar intake in young children has been consistently linked to poor health outcomes, including obesity and metabolic disorders.

The findings come as the US Food and Drug Administration (FDA) is considering new guidelines for front-of-package nutrition labels, healthy claims and marketing of food products to children. The US currently does not require warning labels on any food products that are high in sugar, sodium or calories.

What Are Ultra-Processed Foods?

Ultra-processed foods (UPFs) are industrially manufactured products made with ingredients and additives rarely used in home cooking, including preservatives, emulsifiers, artificial sweeteners, colorants, flavor enhancers, and hydrogenated oils. They are generally high in refined carbohydrates, added sugars, unhealthy fats, and sodium, while being low in fiber and other essential nutrients.

Research suggests that diets high in UPFs may promote chronic inflammation, disrupt the gut microbiome, and impair insulin regulation over time, potentially increasing the risk of obesity, type 2 diabetes, cardiovascular disease, and other chronic illnesses from an early age.
