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.

If you're making a smoothie for a health boost, especially for your brain and heart, you might want to leave out bananas. New research suggests that adding a banana to your drink can actually block your body from absorbing key healthy compounds.

Bananas have always been a big favorite for healthy drinks and desserts. You may have seen many healthy smoothie recipes like banana and coffee smoothie, or bananas and berries, being listed along with other healthy food recipes. While it does have many health benefits, how healthy it is with other nutrients involved has been questioned.

Researchers at the University of California-Davis found that bananas interfere with the absorption of powerful nutrients called flavanols. These compounds are fantastic for health, but if you blend them with a banana, you might not get the benefit you're looking for.

Should You Add Bananas In Health Smoothies?

The researchers found that bananas block how well we absorb flavanol. Flavanols are beneficial natural chemicals found in foods like berries, apples, grapes, and cocoa. When you eat enough of them regularly, they are known to help your memory, reduce swelling inside your body, which is called inflammation, and make your blood flow better.

So, why does the banana stop this? The culprit is a specific enzyme, a kind of protein, that is found in high amounts in bananas. It's called polyphenol oxidase (PPO). This is the same enzyme that makes a peeled banana or apple slice turn brown quickly. The researchers found that when PPO mixes with flavanols in the blender, it somehow stops your body from being able to use them. Lead researcher Javier Ottaviani said it was surprising to see how quickly even just one banana dropped the levels of flavanols your body could absorb.

Why Do Bananas Block Nutrients?

The scientists conducted a very clear experiment to figure this out. They had people drink three different things and then measured the flavanols in their bodies, by testing their blood and urine:

The Banana Test

A smoothie made with banana, which is high in the PPO enzyme.

The Berry Test

A smoothie made with mixed berries, which are low in the PPO enzyme.

The Control Test

A plain capsule of pure flavanols, just to see what 100% absorption looked like.

The results were impossible to ignore, the people who drank the banana smoothie had 84% less flavanols show up in their system compared to the people who took the pure flavanol capsule. This clearly proved that the banana was the reason the healthy compounds weren't getting absorbed.

How to Get Your Daily Flavanols?

If you're trying to meet the daily recommendation of flavanols, which is about 400 to 600 milligrams, to help your heart and overall health, you need to be smart about your smoothies.

The main takeaway is to skip the bananas if you're mixing it with high-flavanol foods like berries. If your smoothie already contains ingredients that are low in the PPO enzyme—like berries, pineapple, oranges, mango, or yogurt—then you are maximizing the amount of healthy flavanols your body will actually get. This finding opens the door for more research into how simple acts of cooking or preparing food, like how you brew tea (a major flavanol source), can change the nutrients you absorb.

Intermittent fasting is an eating plan that alternates between periods of eating and fasting on a set schedule. Studies show that intermittent fasting can help manage weight and even reduce the risk of certain diseases. But some people worry whether fasting could harm the brain or lead to cognitive decline.

Researchers addressed this concern in a paper published in Psychological Bulletin, reporting that short-term fasting of less than 24 hours does not appear to affect the mental performance of adults.

What Is Intermittent Fasting?

Intermittent fasting is an eating pattern that involves alternating between times when you don’t eat and times when you do, sometimes with calorie restrictions on specific days.

This practice dates back thousands of years and is woven into several cultural and religious traditions. Scientists began studying it for weight control in the early 1900s, and recent research has expanded to explore its broader health effects.

There are three widely followed types of intermittent fasting, as per Healthline:

• Time-restricted eating: You eat within a fixed time window and fast during the remaining hours. The 16/8 pattern is the most popular, where you eat during an 8-hour window and fast for 16 hours (including sleep). Other variations include 14/10 and 20/4.
• Alternate-day fasting: You rotate between normal eating days and fasting days, when you consume very few calories, around 500 on average. Some prefer spreading this limited intake across the day, while others eat one small meal.
• 5:2 fasting: Instead of alternating daily, this plan limits calorie intake to 500–800 calories on two chosen days each week, while the rest of the week follows a regular eating routine.

Intermittent Fasting and Brain Health: How Are They Related?

Only recently have scientists started exploring how intermittent fasting influences the brain. Early findings suggest it might offer certain cognitive benefits as we age and even help reduce symptoms of anxiety or depression.

“Many people assume fasting will make it hard to focus or perform well at work or school,” said David Moreau, PhD, a neuroscientist at the University of Auckland and senior author of the study. “Our findings show that for most healthy adults, short-term fasting doesn’t significantly impact mental sharpness.”

The research did note that children and teenagers experienced slight declines in attention and memory while fasting, emphasizing the need for a balanced breakfast before school. Adults, meanwhile, tended to perform a little worse later in the day while fasting, possibly because hunger can heighten natural dips in alertness due to circadian rhythm.

“Humans evolved with periods of limited food, so it makes sense our brains can function well without constant eating,” Dr. Moreau added. “Still, younger people seem more affected, which aligns with their higher energy demands.”

Intermittent Fasting Unlikely to Cause Cognitive Decline

According to recent studies, as per Healthline, intermittent fasting is unlikely to cause cognitive decline. Experts who reviewed the findings say it reinforces the safety and benefits of fasting. “The key takeaway is that fasting doesn’t harm mental performance,” said Dr. Mir Ali, bariatric surgeon and medical director at the MemorialCare Surgical Weight Loss Center, California.

The meta-analysis reviewed 63 studies across the world, including over 3,400 participants. Most individuals fasted between 8 and 24 hours, with a median duration of 12 hours.

Researchers concluded that fasting “neither enhances nor impairs mental performance.” They identified three main factors that influence cognitive function:

• Fasting duration
• Type and timing of the cognitive test
• Individual characteristics, such as age or body composition

They also noted that glycogen—the body’s stored form of glucose provides energy during normal eating. When glycogen levels fall during fasting, the body shifts to using ketones derived from fat as an alternate energy source.

How To Practise Intermittent Fasting?

Intermittent fasting is not suitable for everyone, particularly those with a history of eating disorders or women who are pregnant or breastfeeding. However, for most healthy adults, it offers flexibility in timing and approach.

During fasting hours, you can still drink water, black coffee, or unsweetened tea. Light exercise is also permitted. Healthline advises focusing on nutrient-rich meals during eating periods, staying hydrated, and maintaining good sleep habits.

For beginners, it’s best to start slowly, perhaps by fasting for 6 to 8 hours at first, then gradually extending to 8–10 hours, and eventually to the more balanced 12–14-hour fasting window.

Coffee is almost everyone's favorite, whether it is to get you up and moving in the mornings, especially when the winter comes in, or to ensure your productivity is at best, or for when you hit the gym. And, if you are wondering to drink it or not with heart disease, the good news is, you can! A new study published in JAMA Network says so.

Traditionally, coffee has been associated with being a troublemaker, however, this thing could soon be put in past, as scientists are now asking people to drink coffee, because it might actually be good for their heart.

In a first-of-its-kind clinical trial, researchers found that a daily cup of caffeinated coffee could actually protect the heart.

What Was The Study?

The study is led by researchers from UC San Francisco and the University of Adelaide. The study noted that drinking coffee every day may reduce the risk of Atrial fibrillation or A-Fib. Published in JAMA Network, the study said that coffee worked best against the condition, which is an irregular and often rapid heart rhythm that causes symptoms like palpitations, fatigue, and breathlessness. All of these could significantly increase the risk of stroke and heart failure.

It is caused by chaotic electrical signals in the upper chambers of the heart – known as atria, which leads to ineffective blood pumping and can cause blood clots to form.

Till now, those with A-Fib were advised not to drink caffeine out of fear that it may trigger symptoms. However, this trial – named DECAF - concluded that drinking a cup of caffeinated coffee a day reduced the deadly condition by 39%.

What Are The Experts Saying?

As per the researchers, and other scientists, coffee increases physical activity and reduces atrial fibrillation. Since caffeine is a diuretic, it potentially reduces blood pressure and, in turn, lowers the risk of A-Fib.

“There are many other ingredients in coffee that also have anti-inflammatory properties with positive effects,” said senior author Dr Gregory M. Marcus, who holds the Endowed Professorship in Atrial Fibrillation Research and is an electrophysiologist at UCSF Health.

How Was The Study Conducted?

Researchers wanted to understand how coffee affects people with A-Fib, so they enrolled 200 coffee drinkers who had persistent atrial fibrillation or atrial flutter. All of them were already scheduled for electrical cardioversion, a procedure that uses a controlled electric shock to reset the heart’s rhythm.

Participants were randomly split into two groups. One group had to drink at least one cup of caffeinated coffee or an espresso shot every day. The other group had to avoid all coffee and caffeine for six months. By the end of the study, the coffee group had a 39 percent lower risk of A-Fib coming back. They also showed signs of reduced inflammation.

The researchers suggested that coffee might help simply because it replaces less healthy drinks. “The results were astounding. Doctors have long told patients with A-Fib to cut back on coffee, but this trial suggests coffee is not only safe but may actually protect the heart,” said lead author Dr Christopher X. Wong of UCSF and the University of Adelaide and Royal Adelaide Hospital.
