Feeding peanut butter to babies — starting during infancy and continuing until age 5 — has been shown effective in reducing allergies into adolescence, according to a new study by King’s College London.

The LEAP-Trio study, published on Tuesday in NEJM Evidence, showed that children who consumed peanuts early in life were 71% less likely to develop peanut allergies all the way up to 13 years of age.

This was a follow-up to the Learning Early About Peanut Allergy (LEAP) clinical trial. The National Institute of Allergy and Infectious Diseases (NIAID) sponsored and co-funded both studies.

In the original trial, half the participants were asked to consume peanuts regularly from infancy until age 5, while the other half were asked to avoid the food during that period.

Researchers found that early introduction of peanuts reduced the risk of peanut allergy at age 5 by 81%.

This latest trial included 508 participants from the original study, averaging 13 years of age. 

The children were given peanuts in a “carefully controlled setting” to gauge any allergic reactions.

Peanut allergies were “significantly more prevalent” among the children who avoided peanuts in the first five years of life.

“Regular, early peanut consumption reduced the risk of peanut allergy in adolescence by 71% compared to early peanut avoidance,” the study authors wrote.

This effect persisted regardless of whether the children had eaten peanuts regularly or avoided them over a period of many years.

“The key finding of this study is that early consumption of peanut, starting early in the first year of life, confers long-term protection against peanut allergy all the way into adolescence, even without continued consumption of peanut beyond the age of five years,” lead study investigator Gideon Lack, a professor at King’s College London, told Fox News Digital.

“This is the first study to establish long-term oral tolerance as a protective strategy against peanut allergy.”

To prevent peanut allergy, young babies as early as 4 months of age should be given peanuts in the form of peanut puffs or peanut butter “regularly and frequently” — at least three times a week — over the first four to five years of life, the researchers recommended.

“I was not entirely surprised, but nevertheless impressed by the strong protective effect of early peanut consumption preventing peanut allergy all the way into adolescence,” Lack noted. 

“This indicates that lifelong tolerance may have been achieved.”

“Early introduction of infant-safe peanut foods has been proven to help prevent peanut allergies, especially but not exclusively in infants at risk for peanut allergies,” a registered dietitian told Fox News Digital.  (iStock)

Sherry Coleman Collins, a food allergy dietitian in Marietta, Georgia, was not involved in the study but shared her insights on the topic.

“Early introduction of infant-safe peanut foods has been proven to help prevent peanut allergies, especially but not exclusively in infants at risk for peanut allergies,” she told Fox News Digital. 

“In this study, they found that even if children who ate peanut foods in infancy stopped eating peanuts for a period of time, they were still protected against developing a peanut allergy,” Collins continued.

This supports the idea that tolerance to foods developed in infancy can extend into adolescence, according to Collins. 

“Infants who have moderate to severe eczema and/or egg allergy should discuss early introduction of peanut foods to help prevent peanut allergies because they are at highest risk,” she advised.

The study did have some limitations, Lack acknowledged.

“One weakness of the study is that it was carried out in a high-risk population of babies with severe eczema or hens egg allergy,” he told Fox News Digital. 

“However, the findings of the original LEAP study have now been replicated in other lower-risk normal populations and therefore are applicable to the general population.”

These findings could likely be effective for other types of food allergies, the researchers said.

FIRST ON FOX: With nearly two-thirds of nurses in the United States experiencing burnout — including 69% of those under 25 years of age, according to the American Nurses Association — many in the industry are calling for change.

A recent survey by AMN Healthcare, a health care workforce solutions company based in Texas, found that most nurses aren’t optimistic about improvements, with 80% saying they think the year 2024 will be either “no better or worse” than last year and 38% of nurses expecting it to be worse.

“The concerns that many nurses have about their profession were not created by COVID-19 and have not gone away now that the crisis has passed,” Robin Johnson, group president of nursing solutions at AMN Healthcare, who administered the survey, told Fox News Digital.

“Many nurses still feel overworked and undercompensated,” she said. 

“What they want to see is a change in their daily working conditions — better hours, fair compensation and more time with their patients.”

Amid the ongoing challenges faced by today’s nurses, six people in the profession shared what they wish they’d known before they decided to enter the field — and what advice they’d give to newcomers.

Lisbeth Votruba: ‘Nurses don’t have enough influence’

Lisbeth Votruba, a third-generation registered nurse in Belmont, Michigan, is also the chief clinical officer of AvaSure, a virtual health care platform. 

“When I first entered the profession in the 1990s, I was surprised to learn that although nurses are held to high ethical and legal standards, they do not have the influence to match that level of accountability,” said Votruba. 

“I see trends to show this is changing, and I am doing what I can as a member of the senior leadership team of a technology company to make sure the voice of nurses is heard as health care technology is being designed,” she said.

“Nurses must be at the table for every discussion about technology that impacts the patient,” she said. 

Mat Wellnitz: ‘Wish I’d known the stress involved’

Mat Wellnitz, a registered nurse in Big Rapids, Michigan, recently retired from a rural hospital after more than 34 years, most of them spent in critical care.

“I wish I’d known the amount of stress that’s involved in nursing,” said Wellnitz. 

“I would have taken more time off for myself. It wasn’t until about a week after I retired that I realized how much stress I was blinded to.”

He added, “I used to lie down and instantly could feel my heart pounding, always thinking about work. But not anymore — and I sleep better.”

Larry Williams: ‘Your work impacts your overall health’

Larry Williams worked as a registered nurse at California’s Stanford Hospital in the intensive care unit before retiring in 2021.

“I went into nursing with my eyes wide open … There were no surprises because I worked in two different hospitals while going to school,” said Williams. 

“My advice to anyone considering nursing and health care in general is to find a way to actually work in a hospital prior to graduating. Pay attention to your strengths and weaknesses and choose an area that fits you as a person.”

“It is not the career for everyone, but it was for me.”

He also told Fox News Digital, “While you are working, pay attention to how your work is impacting your overall health. Not everyone is cut out to work in the ICU. I still have occasional work dreams, and I remember the names and faces of people I cared for who did not survive.”

Said Williams, “That is balanced by the happy memories of my peers as well as lives that I have touched … It is not the career for everyone, but it was for me.”

Karie Ryan: ‘Bedside nursing is not the only option’

“I wish I had known that bedside nursing is not the only option available in order to make an impact,” she told Fox News Digital. 

“There are so many specialty opportunities, including nursing informatics.”

She added, “If nursing schools offered exploration in nursing informatics and other subspecialties, it would open a new world of possibilities not only to those entering the field, but as a consideration for nurses later in their career who may want to transition but remain in the profession.”

Katelynn Blackburn: ‘Constant pressure took a toll’

“I wish I would have known more about how my personality would affect my profession in the medical field,” said Katelynn Blackburn. 

“I am empathetic and caring; however, the field itself comes with a lot of pain and anxiety for patients and their families,” she said. 

“The constant exposure to hardships, on top of the pressure of providing comfort and support to patients and their families, definitely took its toll on me.”

She added, “I wish I had thought less about the income and salary and more about what the actual job entails. You must find something you are passionate about and ensure that it will secure your family financially.”

Noted Blackburn, “I have always had an entrepreneurial mindset and a personality driven to achieve more — so I decided to leave to pursue something I felt more aligned with.”

Michele Acito: ‘Emotional bond is deep’

Michele Acito is executive vice president and chief nursing officer at Holy Name Medical Center in New Jersey. She joined Holy Name in 1989 as a telemetry nurse, working in the cardiovascular and intensive care units before she was promoted. Earlier in her career, she worked as a staff nurse in orthopedics at St. Joseph’s University Medical Center.

“I wish I’d known about the emotional commitment I was making,” said Acito.

“We know we will be committed to providing the best care … but the emotional bond and commitment you make to patients and families as they navigate through life-changing events is deep. As a nurse, you quickly learn how to comfort, celebrate, support and educate patients and families through the good and the difficult times.”

She added, “Today, nearly 40 years into my career, I am able to reflect on how my training as a nurse helped me to help patients and families during their most vulnerable moments. It is what makes me proud to be a nurse.”

“Another thing I wish I had known before entering the profession,” said Acito, “was how complex it would be to blend a career, a young family and a household.”

“Nursing was the perfect career for someone striving to manage it all.”

But “what I realized was that nursing was the perfect career for someone striving to manage it all and find fulfillment and purpose on a personal and professional level. It requires thoughtful prioritization, planning and support.”

Other insights: ‘A nurse is a career learner’

Acito also shared the importance of ongoing education to set up nurses for success.

“Having graduated from a BSN program, I thought I was educationally set for my entire career,” she said. “I quickly realized that was not true.”

She noted, “A nurse is a career learner. Obtaining degrees is very important to remain current with theory — but learning through continuing education is paramount to staying current in practice.”

“Technologically, nothing remains the same in health care,” said Acito. “It’s an ever-evolving field. Pursuing a nursing career in hospitals and health systems that are committed to investing in innovation and technological advancements is critically important.”

Acito also pointed out, “What I did not know then, but I know today, is that I made the best career choice when I decided to be a nurse. The hours are difficult, the stress intense, the emotional commitment deep — but the rewards are innumerable.”
