Allergy Statistics
The economic impact of childhood food allergy in the United States
Key points: The overall economic cost of food allergy was estimated at $4184 per year per child. This cost included clinician visits, emergency department visits, and hospitalizations; time taken off work for medical visits, out-of-pocket expenses, special foods, and work costs related to a caregiver needing to leave or change jobs. Caregivers reported a willingness to pay an estimated $3504 per year per child for food allergy treatment. (most food allergy websites reference this study)
The Economic Burden of Food Allergy: What We Know and What We Need to Learn
Epidemiology and Burden of Food Allergy
Key points: 59 new therapeutic agents approved by the FDA from 2015 to 2016, the median estimated direct cost of pivotal efficacy trials was $19 million, with half of the trial cost estimates ranging from $12 million to $33 million. At the extremes of the distribution were 100-fold cost differences, and patient enrollment varied from fewer than 15 patients to more than 8000 patients. A critical question in health care is the extent of scientific evidence that should be required to establish that a new therapeutic agent has benefits that outweigh its risks.
Prevalence and Severity of Food Allergies Among US Adults
Key points: A significant number of adults in the US have food allergies. This study examines the prevalence, severity, and health care utilization related to food allergies among US adults. Based on a cross-sectional survey of over 40,000 adults, it was found that 10.8% of US adults (over 26 million) have convincing food allergies, though nearly 19% self-reported having a food allergy. The most common allergens were shellfish, milk, peanuts, tree nuts, and fin fish. Notably, 51% of food-allergic adults experienced severe reactions, 45% were allergic to multiple foods, and 48% developed food allergies as adults. The study highlights the need for proper testing and counseling to prevent unnecessary food avoidance and improve quality of life.

Peanut Allergy
Fatty-Acid-Based Membrane Lipidome Profile of Peanut Allergy Patients: An Exploratory Study of a Lifelong Health Condition
Key points: Results: Increased omega 6:3 fatty acid ratios were found in the allergic population compared to the non-allergic control group.
Factors Associated with the Development of Peanut Allergy in Childhood
Key points: There was no evidence of peanut allergy linked to the maternal diet, and peanut-specific reaction proteins were not detectable in the cord blood of the children Peanut allergy was independently associated with other factors including intake of soy (about 80% of soy is acid based per serving)
Comprehensive metabolomics identifies the alarmin uric acid as a critical signal for the induction of peanut allergy
Key points: High acid levels were found in mice and similarly high levels were also found in children with peanut allergies. When acid levels were lowered in the mice, peanut allergy markers reduced; when they added acid back in the allergy symptoms returned. Elevated acid level likely plays a critical role in the development of peanut allergies, likely due to its ability to activate skin surface immune cells.
Multiscale study of the oral and gut environments in children with high- and low-threshold peanut allergy
Key points: Children with high peanut allergies showed evidence of bacterial infection and poor levels of healthy bacteria in the gut which aids in digestion and the immune response in the intestine. These findings support inclusion of germ elimination and gut restoration as part of the process to reducing and eliminating allergies reactions, an alternative to simply avoiding trigger foods, as the absence of normal healthy gut bacteria opens the door for a lowered immune response and an increased chance for food reactions.
The age-specific microbiome of children with milk, egg, and peanut allergy
Key points: This study assessed the microbiome of children with milk, egg or peanut allergy (<3 years, 3-18 years) compared with similar aged children without food allergy. Groups were not significantly different in age, gender at birth, race, mode of delivery, breastfeeding duration, or antibiotic exposure. Dysbiosis associates with food allergy, most prominent in older children with peanut allergy. Younger children with and without food allergy have fewer differences in gut microbiota. These findings support gut restoration as part of the process to reducing and eliminating allergies reactions, an alternative to simply avoiding trigger foods.
Enhanced Gut Microbiome Capacity for Amino Acid Metabolism is associated with Peanut Oral Immunotherapy Failure
Key points: This study revealed that when peanut OIT doesn't work, it may be related to issues with bile levels and difficulty with amino acid management which are key in peanut digestion. Peanuts are high in protein and fats, which requires bile and a working amino acid breakdown pathway in order to digest. Peanut allergy is likely associated with difficulty digesting peanuts, which is why solutions to resolving peanut allergies could involve a focus on liver and gallbladder health in the production and management of bile, in addition to optimizing acid metabolism pathways.
Key points: OIT that includes berberine and dong quai could improve peanut tolerance with more lasting results.
Immunity and Allergies
The pathophysiology of anaphylaxis
Key points: "Although there is broad consensus on many aspects of the treatment of anaphylaxis, such recommendations are based largely on observational studies, extrapolation from retrospective case reviews, and a few clinical trials." Anaphylaxis symptoms look different depending on the tissues involved in the reaction. In addition to the traditional symtptoms, reactions can include intense itching, welts/hives, nausea/vomiting, abdominal pain, and diarrhea.
Blood Gas Temperature Correction
Key points: traditional laws of physiology (ex: Henderson-Hasselback Equation) state that blood becomes more acidic as temperature rises. At more neutral temperatures, bicarbonate is present in blood which is more basic. As temperature rises, it's chemical structure changes to carbon dioxide which makes blood more acidic. The reverse happens when temperature decreases and blood can return to a more basic state.

FAQS
What is holistic nutrition?
Holistic nutrition is a holistic approach to health and wellness that focuses on the whole person, not just their diet. It takes into account all aspects of your life, including your physical and mental health, your environment, and your relationships. Holistic nutritionists believe that food is a powerful tool that can be used to heal the body, mind, and spirit.
What is the difference between a holistic nutritionist and a registered dietitian?
A holistic nutritionist is a practitioner who uses food and lifestyle changes to promote health and well-being. Holistic nutritionists typically have a background in nutrition, but they are not required to have a degree from an accredited university.
How much does it cost to see a holistic nutritionist?
The cost of seeing a holistic nutritionist can vary depending on the practitioner's experience, location, and the services offered. Most holistic nutritionists charge by the hour, but some may also offer packages or discounts.
