How to Boil an Egg? Scientists Claim to Have Cracked the Recipe.

A colleague approached Ernesto Di Maio, a materials scientist in Naples, Italy, and an expert in plastic foams, with a blunt suggestion: “You should do something cooler.” The colleague had a project in mind, Dr. Di Maio recalled. He wanted a perfectly boiled egg.

The task was harder than it might seem, as many home cooks know. The yolk and the egg white, or albumen, have different chemical compositions, which call for different heating temperatures. Dr. Di Maio and his colleagues also welcomed the chance to one-up the Michelin-star chef Carlo Cracco, an egg evangelist who charges $52 for an egg yolk dish at his restaurant in Milan.

The scientists devised a way of cooking an egg that requires no special culinary skill or fancy gadgets. It took about 300 eggs, though the researchers “didn’t eat all of them,” said Pellegrino Musto, a polymer expert at the National Research Council of Italy.

The researchers said their method, published on Thursday, preserves the distinct textures of the egg as well as its nutritional value.

The two parts of the egg require different cooking temperatures because they have different chemical components. “The albumen is mainly composed of water and proteins,” said Emilia Di Lorenzo, a graduate student in Dr. Di Maio’s lab at the University of Naples Federico II who recently published a paper on foaming pizza. “Yolk, on the other hand, is much richer in nutrients.”

Hard-boiling an egg is a popular approach that calls for at least 10 minutes of immersion in boiling water. That is long enough for the yolk to be thoroughly cooked. But it’s also plenty of time for the albumen’s proteins to unfold and clump, expelling water molecules as they become heated. The approach can also create a green ring around the yolk, which indicates the presence of smelly ferrous sulfide.

“Many times people say that they don’t like the rubberiness of the egg white, or the graininess of the yolk in a hard-boiled egg,” said Nelson Serrano-Bahri, a chef and the director of innovation at the American Egg Board, the egg industry’s main trade association, which has lately been dealing with soaring prices and worries about the bird flu.

A soft boil, on the other hand, needs a much shorter cooking period. That keeps the albumen from turning hard — but may also keep the yolk too soft. Ms. Di Lorenzo explained that the yolk is rich in lipids which, when heated, become more fluid. Though some people prefer a runny yolk, others find it revolting.

A third method, known as sous vide, cooks an egg for an hour in a water bath of 150 degrees Fahrenheit. That’s the ideal temperature for the yolk, but the prolonged exposure is less optimal for the albumen because the water is not hot enough to denature its proteins.

Ms. Di Lorenzo was blunt about the sous vide approach: “It’s runny. I am not a big fan.”

The scientists’ new method, derived with the help of fluid dynamics software, calls for alternating between boiling and lukewarm water: The egg gets two minutes in 212-degree water, followed by two minutes at 86 degrees, with the cycle repeated eight times. Dr. Di Maio explained that the average temperature of the two immersions, 150 degrees, is ideal for the yolk, while the hotter bath is sufficient to cook the albumen.

“The very key of our method is to have a well-cooked albumen without wasting the yolk,” Dr. Di Maio said.

Relative to the other methods, the periodic baths did a better job of preserving the egg’s nutrients, the study found. The authors noted a higher concentration of polyphenols, compounds that protect against DNA damage.

“It’s probably brilliant — but who is the method for?” asked Deb Perelman, who runs the popular Smitten Kitchen blog. “For home cooking, there’s always a necessary balance of perfect versus a reasonable effort.”

Her preferred foolproof method involves a long ice bath after the egg is cooked. In a recipe for The New York Times, J. Kenji López-Alt proposed steaming the egg in a single inch of water.

“It’s a matter of taste,” Ms. Di Lorenzo said. If science is universal, food is deeply personal. Some people even eat raw eggs.

There is one big drawback to the new Italian technique. “It’s more difficult to peel the periodic egg because everything is softer,” Dr. Di Maio said.

But Mr. Serrano-Bahri said that the Egg Board was on the case. “We are running a study to figure out that,” he said. “I could have an answer for you in the coming months.”

Diabetes surge among Americans could be driven by ‘healthy’ breakfasts, doctor warns

Diabetes surge among Americans could be driven by ‘healthy’ breakfasts, doctor warns

NEWYou can now listen to Fox News articles!

Americans consume foods every day that are marketed as “healthy,” when they could be quietly destroying their health, one doctor warns.

Dr. Mark Hyman, physician and co-founder of Function Health in California, says that much of America’s daily diet is filled with unhealthy ingredients.

“The amount of refined starches and sugars that are everywhere is just staggering to me, given what we know about how harmful they are,” he shared in an interview with Fox News Digital. “I don’t think people really understand.”

Hyman, author of the new book “Food Fix Uncensored,” said he’s “astounded” by what people are eating, especially for breakfast.

“People just eat sugar for breakfast,” he said. “They have muffins, they have bagels, they have croissants, they have sugar-sweetened coffees and teas.”

In addition to the traditionally sweet options for breakfast, some cereal brands and breakfast staples have adopted new “protein-packed” menu items and products, following health trends that encourage eating more protein.

“Highly processed food is not food.”

“Now, we’re seeing this halo of protein in certain things,” Hyman said, mentioning that many protein smoothies are “full of sugar.”

The doctor also noted that some popular cereals are now marketed as having protein in them. “My joke is, if it has a health claim on the label, it’s definitely bad for you,” he said.

Instead of starting the day with a “quick fix” or processed food, Hyman suggests choosing whole sources of protein and fat for breakfast, adding that “if there’s a little carbohydrate in there, it’s fine.”

For his own breakfast, Hyman said he has a protein shake with whey protein, avocado and frozen berries. Eggs and avocados are also a great protein-and-fat combo option, he added.

“It’s not that complicated — people need to just think about their breakfast not being dessert,” he said. “No wonder we’re in this cycle of obesity and diabetes. One in three teenage kids now has type 2 diabetes or pre-diabetes. That’s just criminal.”

Instead of counting calories and being in a caloric deficit as a way to lose weight and stay healthy, Hyman instead suggests focusing on how certain foods make you feel and how they impact your health.

“When you look at the way in which different types of calories affect your biology, you can just choose what you’re eating, and then you don’t have to worry about how much,” he told Fox News Digital.

“For example, if you eat a diet that doesn’t cause your insulin to spike — which is low in starch and sugar, higher in protein and fat — you won’t develop those swings in blood sugar, you won’t develop the spikes in insulin, you won’t deposit hungry fat … You will break that cycle.”

People are more likely to “self-regulate when they eat real food” instead of processed foods, which “bypasses the normal mechanisms of satiety, fullness and brain chemistry,” according to Hyman.

“Ultraprocessed food and junk food or highly processed food is not food,” he said. “It doesn’t support the health and well-being of an organism. It doesn’t do that. It does the opposite.”

Scientists make startling discovery when examining prostate cancer tissue

Scientists make startling discovery when examining prostate cancer tissue

NEWYou can now listen to Fox News articles!

Small fragments of plastic were found in the tumors of most prostate cancer patients, according to a new study from NYU Langone Health. 

In past studies, microplastics have been found in almost every human organ and in bodily fluids, but their impact on human health still isn’t fully understood.

The researchers analyzed tissue samples from 10 patients with prostate cancer who underwent surgery to remove the entire organ. 

Using visuals of both benign samples and tumor samples, as well as specialized equipment, the scientists identified plastic particles in 90% of the tumor samples and 70% of benign tissue samples, according to the study press release.

The cancerous tissue contained on average more than double the amount of plastic as healthy prostate tissue samples, the study found. This equates to about 40 micrograms of plastic per gram of tissue compared to 16 micrograms.

Researchers avoided contaminating the samples with other plastics by substituting standard tools with those made of aluminum, cotton and other non-plastic material, the release noted.

The scientists say this is the first direct evidence linking microplastics to prostate cancer.

“By uncovering yet another potential health concern posed by plastic, our findings highlight the need for stricter regulatory measures to limit the public’s exposure to these substances, which are everywhere in the environment,” said senior study author Vittorio Albergamo, assistant professor in the department of pediatrics at NYU Grossman School of Medicine, in the release.

The study findings were presented during the American Society of Clinical Oncology’s Genitourinary Cancers Symposium in San Francisco on Feb. 26.

“What is most striking is not that microplastics were detected, but that they were found embedded within tumor tissue itself,” Dr. David Sidransky, oncologist and medical advisor at SpotitEarly, a startup that offers an at-home breath-based test to detect early-stage cancer, told Fox News Digital.

“While complete avoidance is unrealistic, people can take practical steps to reduce exposure.”

“We already know microplastics are present in water, air, blood and even placental tissue. Their detection in prostate tumors suggests systemic distribution and long-term bioaccumulation,” added Maryland-based Sidransky, who was not involved in the study.

Study limitations

Albergamo cautioned that a larger sample is needed to confirm the findings. Additionally, Sidransky noted that the presence of microplastics alone does not prove they cause cancer.

“Tumors can act as ‘biologic sinks,’ meaning they may accumulate circulating particles simply because of altered vasculature and permeability,” he said.

A key unanswered question, according to the doctor, is whether microplastics are biologically active in ways that “promote DNA damage, immune modulation or chronic inflammation within the prostate.”

About one in eight men in the U.S. will be diagnosed with prostate cancer at some point in their lifetime, according to the Centers for Disease Control and Prevention.

The most actionable step men can take is appropriate screening and early detection, according to doctors. (iStock)

For those concerned about microplastics, Sidransky offered some insights.

“I believe the appropriate response is curiosity, not panic, and a commitment to understand more,” he said.

“While complete avoidance is unrealistic, people can take practical steps to reduce exposure, such as minimizing heating food in plastic containers, reducing bottled water consumption when possible, and favoring glass or stainless steel alternatives.”

The most actionable step men can take, however, is getting appropriate screenings to help ensure early detection, according to the doctor. Screening discussions should be individualized based on age, family history and other risk factors.
