INCREASE IN FOOD ALLERGIES
re-write
There is evidence to suggest that the consumption of junk food, which is high in advanced glycation end products (AGEs), could be contributing to the increase in food allergies. However, it is important to note that there are many potential causes of food allergies, and a combination of genetic and environmental factors likely plays a role.
AGEs are compounds that are formed when sugars and proteins react with each other in a process known as glycation. They are found in high levels in many processed foods, such as fast food, cakes, and snacks, and have been linked to a range of health problems, including inflammation, insulin resistance, and oxidative stress.
The study referenced in the question found that children with food allergies had higher levels of AGEs under their skin than children with respiratory allergies or no allergies. This suggests that there may be a link between AGEs and food allergies, although further research is needed to confirm this.
It is worth noting that many other factors have been implicated in the rise in food allergies, including changes in diet, changes in the gut microbiome, and increased exposure to environmental toxins. It is likely that a complex interplay of factors is responsible for the increase in food allergies seen in recent years.
When a sugar molecule binds to a protein or fat under heat, it results in glycation. This is a common occurrence when cooking foods such as steak or potatoes in oil, giving them a delicious brown crust. However, this process is not particularly beneficial for your health. Highly processed foods tend to have higher levels of advanced glycation end products (AGEs), which are formed during glycation.
According to Dr. Roberto Berni Canani, an associate professor of pediatrics at the University of Naples and lead investigator of a study on the subject, higher levels of AGEs among children with allergies might indicate a “missing link” in current models of food allergies.
While prior studies have suggested that dietary sources of AGEs may contribute to the increasing prevalence of food allergies, Dr. Wendy Sue Swanson, a pediatrician at Seattle Children’s Hospital and chief medical officer of Before Brands, points out that there are multiple factors at play. It is crucial to understand all the ways in which our environment has influenced the development of food allergies. Although processed foods may lack protein diversity, more research is required to comprehend the precise role of AGEs in food allergy development.
Regardless of the exact cause, the prevalence of food allergies has increased by nearly 200% in the past two decades, according to Dr. Tania Elliott, an associate attending physician at NYU Langone Health and a national spokesperson for the American College of Allergy, Asthma, and Immunology. Dr. Lakiea Wright, a physician in internal medicine and allergy and immunology at Brigham and Women’s Hospital in Boston and the medical director at Thermo Fisher Scientific, agrees that the cause of food allergies is thought to be multifactorial, involving both genetics and the environment.
Dr. Wendy Sue Swanson, a pediatrician at Seattle Children’s Hospital, listed several primary factors believed to contribute to the rise in food allergy incidence in a Healthline article:
- Timing of introduction of foods: Delaying the introduction of highly allergenic foods, such as peanuts and eggs, is believed to have contributed to the increase in food allergies.
- Hygiene hypothesis: We are now cleaner, using antibacterial soaps and hand sanitizers. However, our immune system may have become more tolerant with more exposure to microbes.
- Climate change: The way crops grow due to temperature shifts may make them more immunogenic, provoking the immune system and leading to food allergy development.
- Dietary patterns: The consumption of more processed foods and fewer fruits and vegetables globally affects our gut microbiome.
- Genes and environment: This includes genetic makeup and maternal exposures to allergens, including prenatal maternal diet, pollution, and chemicals.
Dr. Douglas Jones, from Rocky Mountain Allergy at Tanner Clinic in Utah, also suggested that early antibiotic use may influence gut health and increase the likelihood of developing allergies. Early use of antacids in children may also be problematic, as it changes the pH of the stomach and how the body perceives the absorbed food.
Allergies can be prevented or treated by taking various approaches. In the case of peanut allergies, environmental approaches such as early introduction of peanuts into the diet may help in preventing allergies. However, attempts at oral immunotherapy have had mixed results, and researchers are still working on a monthly injection that could help children with peanut allergies. For other allergies, early introduction of a variety of foods for babies may be helpful. Pediatricians are advising parents to introduce potentially allergenic foods at an early age, typically starting at 4 to 6 months, when a baby’s immune system is still developing. This approach builds tolerance over time so that the baby can grow accustomed to a wide range of foods. For everyone else, the primary treatment for food allergies is to avoid the allergenic foods by reading labels and working closely with a doctor. Vaccines for allergies are still in the development phase.

Food allergies have become increasingly prevalent over the past few decades, with a nearly 200% increase in incidence. While the exact causes of this rise in food allergies are not yet fully understood, research has identified several potential factors that may be contributing to this trend.
One such factor is the consumption of processed and junk foods, which tend to be high in advanced glycation end products (AGEs). AGEs are compounds that form when proteins or fats bind with sugar molecules during cooking or processing. These compounds are known to be associated with inflammation, oxidative stress, and insulin resistance, and they have been linked to a range of health problems.
A study of children with food allergies found that they had higher levels of AGEs under their skin than children with no allergies or only respiratory allergies, suggesting a possible link between AGEs and food allergies. However, more research is needed to confirm this relationship.
Other factors that may contribute to the rise in food allergies include changes in diet, changes in the gut microbiome, increased exposure to environmental toxins, delayed introduction of allergenic foods, use of antibiotics and antacids at an early age, and genetic and environmental factors.
Prevention and treatment of food allergies can take many forms, including early introduction of allergenic foods, avoidance of allergenic foods, and oral immunotherapy. Researchers are also working on developing vaccines for food allergies. Pediatricians advise introducing potentially allergenic foods at an early age to build tolerance over time and help babies grow accustomed to a wide range of foods. For those with food allergies, reading labels and working closely with a doctor are essential for avoiding allergenic foods and managing symptoms.
