Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects millions of people, both children and adults. The key characteristics are hyperactivity, impulsivity, and inattention. Because of many obstacles, researchers have been searching for other therapies—inclining to include diet intervention to control the symptoms of ADHD more effectively. One interesting area of research is that for chili peppers! Yes, you read it correctly, scientists are studying the effects of chilli peppers in order to help ease symptoms of ADHD through their action on gut microbiota and the gut-brain axis.

The gut-brain axis (GBA) is a two-way communication system that connects the gastrointestinal tract with the central nervous system. It has significant roles in brain function, emotional control, and cognitive processes. The most recent research indicates that gut microbiota- bacteria living in the digestive system can potentially affect ADHD by impacting the production of neurotransmitters and brain structure.

People with ADHD tend to have reduced levels of healthy gut bacteria, including Lactobacillus, and a less diverse gut microbiota. This imbalance can contribute to greater neuroinflammation and oxidative stress, both of which are involved in ADHD pathology.

Gut microbiota also control the production of dopamine and serotonin, two neurotransmitters critical for attention, impulse control, and emotional stability.

Can Chili Peppers Be A Natural Treatment For ADHD?

Chili peppers have bioactive molecules, such as capsaicin, vitamin C, and polyunsaturated fatty acids (PUFAs), that could affect symptoms of ADHD through modulation of the gut microbiota and neurotransmitter concentration.

Capsaicin, the phytochemical in chili peppers, has been found to modulate neurotransmitter levels. Experiments with animals reveal that capsaicin boosts the levels of serotonin and dopamine in the brain, which has the potential to enhance attention and impulse control.

Additionally, capsaicin has been shown to inhibit neuroinflammation and oxidative stress, both of which are associated with ADHD pathology. Through the reduction of these variables, capsaicin could help to decrease some ADHD symptoms. While animal models offer promising information, human studies are needed to ascertain if capsaicin supplementation can produce a concrete effect on ADHD symptoms.

Role of Vitamin C and Gut Microbiobe

Chili peppers are a rich source of vitamin C, a potent antioxidant that enhances immune function, neurotransmitter production, and iron absorption. New evidence indicates that vitamin C can also increase the prevalence of helpful microbes such as Lachnospiraceae in the gut microbiota. Gut microbial balance has been implicated in neurodevelopmental diseases such as ADHD, and vitamin C's activity in regulating gut microbes could potentially be used as a therapy.

Moreover, vitamin C also decreases brain inflammation, which tends to be higher in patients with ADHD.

Chili peppers are also rich in PUFAs, such as omega-3 and omega-6 fatty acids. Studies have established that patients with ADHD tend to have lower levels of omega-3 PUFAs, which are important for brain function, synaptic plasticity, and regulation of neurotransmitters. Omega-3 supplementation has been shown to enhance memory function and boost short-chain fatty acid (SCFA)-producing gut bacteria, which promote brain and gut health.

Given that PUFAs have anti-inflammatory properties and maintain cognitive function, their occurrence in chili peppers contributes to the accumulating data indicating dietary intervention may be effective in modulating ADHD symptoms.

Although chili peppers have bioactive substances that could affect the gut-brain axis and help alleviate ADHD symptoms, their impact is speculative until stricter human trials are carried out. Being a readily available food item, peppers can be used as a possible adjunct therapy, which can be added to conventional ADHD treatments. Peppers, however, cannot be used as a substitute for established medical therapies, including behavioral therapy and prescription drugs.

The developing connection between nutrition, gut microbiome, and ADHD has paved the way for exploring non-medication interventions. Chili peppers, rich in capsaicin, vitamin C, and PUFAs, represent a novel yet unproven method for modulating ADHD symptoms. While early research points towards a possible intervention by chili peppers in modulating neurotransmitter content and minimizing neuroinflammation, human studies are essential to validate the observations.

Introducing Eggs Before Age One May Lower Allergy Risk by 17%: Study

Updated Jun 10, 2026 | 02:00 AM IST

SummaryThe Australian study showed that the reduction in egg allergy was more pronounced in babies with eczema, a known risk factor for food allergies. Among these children, egg allergy rates were reduced from 35 per cent to 22 per cent.

Eggs are a great source of protein. At the same time, they are one of the most common foods that cause allergies in children.

A new study conducted in Australia showed that introducing eggs to children before the age of one may reduce the risk of allergy by 17 per cent. The findings were published in the journal JAMA Pediatrics.

Jennifer Koplin, Associate Professor at the Child Health Research Centre at The University of Queensland, said: “Australia has one of the highest rates of food allergy in the world, with one in 10 infants allergic to one or more foods".

To curb the allergy rates, the Australian infant feeding guidelines, issued by the Australasian Society of Clinical Immunology and Allergy in 2016, revolutionized allergy prevention by advising parents to introduce well-cooked egg and smooth peanut butter soon after starting solid foods, generally around six months of age.

The research, led by a team from UQ and the Murdoch Children's Research Institute, examined 7,200 children in two Australian population-based studies to assess whether egg allergy rates had declined since the introduction of the guidelines. The risk of allergy decreased by 17 per cent among babies who started eating eggs early.

“Most parents followed the guidelines, and these results provide reassurance that this advice will help reduce the chance of their child developing an egg allergy,” Dr Koplin said.

Lesser Allergy In Infants With Eczema

According to Associate Professor Rachel Peters of the Murdoch Children's Research Institute, the reduction in egg allergy was more pronounced in babies with eczema, a known risk factor for food allergies. Among these children, egg allergy rates were reduced from 35 per cent to 22 per cent.

“The introduction of the 2016 guidelines was a major change from most advice given in the 1990s and early 2000s, which recommended parents delay giving eggs and other allergenic foods until 1–3 years of age if there was a strong family history of allergy,” Dr Peters said.

Allergenic Foods Before Age One

Other common allergy-causing foods, such as cow's milk, fish, sesame, wheat, and tree nuts, are also recommended to be included in a child's diet before one year of age. Dr Koplin, however, urged for more research into food allergies.

Common Symptoms of Egg Allergy

According to the Mayo Clinic, egg allergy symptoms usually start a few minutes to a few hours after eating eggs or foods containing eggs. While egg allergies can occur as early as infancy, most children outgrow their egg allergy by age 16.

Egg allergy symptoms can include:

  • Skin swelling or itchy bumps called hives — the most common egg allergy reaction.
  • Stuffy or runny nose and sneezing, also known as allergic rhinitis.
  • Digestive symptoms such as cramps, upset stomach and vomiting.
  • Asthma symptoms such as coughing, wheezing, chest tightness or shortness of breath.

World Food Safety Day 2026: WHO Debunks 5 Dangerous Food Safety Myths

Updated Jun 7, 2026 | 01:00 PM IST

SummaryAs we observe World Food Safety Day 2026, it is crucial to address food myths that can harm anyone. Knowing the 5 dangerous food-related mistakes identified by the World Health Organization (WHO) is important.

Food is arguably one of the most important parts of life, as it is essentially the fuel that the body runs on. Food is so important to life that slight complications, changes, or missteps can cause great harm to you. If the food is unsafe, then that can act like poison as well. According to the World Health Organization (WHO), unsafe food causes around 866 million illnesses and 1.5 million deaths every year.

The WHO, in its recent report, reveals that children under 5 years of age experience 29 per cent of the health burden due to unsafe food, with 143,000 deaths in 2021.

WHO Director-General Dr Tedros Adhanom Ghebreyesus said, “Food safety is not an abstract issue – it touches every meal, every family, every day. Unsafe food has always been a major public health concern, but until now, we lacked the bigger picture of its staggering human and economic toll. These new estimates change that.”

Thus, it is crucial to know what to eat, how to eat, and protect yourself from foodborne diseases. And there is a strong connection between unsafe food and food myths; misunderstandings in the kitchen can cost you dearly, so knowing popular food myths from the global health body, WHO, is crucial.

5 Dangerous Food Safety Myths

Can You Tell If Food Is Safe To Eat By Its Look And Smell?

People often think that the smell and appearance of food can help us know its condition, but it's a complete hoax, as the WHO reports that most microorganisms that can make you sick don’t change the look or smell of the food.

Should Raw Poultry Be Washed Before Cooking?

This is arguably one of the popular food-related misconceptions, as in most households, the washing of chicken before cooking is seen as a healthy practice emphasizing making sure that the raw meat has been properly washed and soaked, but the WHO's report proves otherwise. The global body, washing poultry can spread harmful microorganisms to hands, surfaces, utensils, or other food.

Do Organic Fruits And Vegetables Need To Be Washed?

Some think that fruits and vegetables grown organically do not require washing, as they are not cooked with pesticides or chemical fertilizers, and that is a myth. The WHO said all produce, including organic, should be washed with clean water to remove physical contaminants and reduce the risk from any harmful microorganisms or chemicals.

Can Dishcloths Spread Dangerous Bacteria?

Another common habit is to use dishcloths to clean them after washing, and that is a big no from WHO, as dishcloths and sponges can carry and spread dangerous bacteria.

Do I Have To Refrigerate Leftover Food?

Sometimes people do not keep leftover food outside the refrigerator, and that is also a mistake because food can be dangerous to consume if left at room temperature for more than two hours.

Prediabetes affects more than 600 million people worldwide and is linked not only to an increased risk of type 2 diabetes but also to impaired brain function.

Adding a small quantity of almonds to the daily diet on their own or added to cereal, yogurt, curries, salads, and other dishes may help boost brain health and prevent a decline in cognitive function in adults with prediabetes, experts said.

Almonds contain

  • protein
  • fiber
  • saturated fat and unsaturated fat
  • 24 essential nutrients, including magnesium, potassium, and vitamin E.
A new study, published in the Journal of Nutrition, found improvements in executive function, blood sugar levels, and body composition after 24 weeks of daily almond consumption.

The findings showed that eating just a few almonds each day may benefit cognitive performance, metabolic health, and markers of inflammation and oxidative stress in middle-aged Asian Indian adults with prediabetes.

“Adults with prediabetes are vulnerable to a decline in cognitive function. Our study indicates that just one simple dietary change – adding a small quantity of almonds to the daily diet – may help support brain health and improve cognitive performance in some populations,” said Dr. Anoop Misra, co-investigator and Chairman, Fortis-CDOC Center of Excellence for Diabetes, Metabolic Diseases, and Endocrinology in New Delhi, part of the study.

He noted that daily almond consumption could help lower the risk of prediabetes progressing to type 2 diabetes, a condition associated with an increased risk of dementia.

How Was The Study Conducted?

In a 24-week study, 60 Asian Indian adults aged 40–60 with prediabetes were assigned to either a control group or an almond group.

Those in the almond group consumed 32–42 grams of almonds daily as part of a calorie-matched diet.

Researchers assessed cognitive performance, blood sugar levels, cholesterol, weight, BMI, and waist circumference before and after the study.

What Did Researchers Find?

Participants in the almond group experienced improvements in executive function and processing speed, both key measures of cognitive performance.

They also demonstrated better blood sugar control, including lower fasting blood glucose, lower blood glucose levels two hours after eating, and improvements in HbA1c, a marker of long-term blood sugar control.

Additional metabolic benefits included significant reductions in body weight, body fat, BMI, waist circumference, total cholesterol, and LDL cholesterol.

Participants consuming almonds also showed improvements in markers related to inflammation and oxidative stress.

“The findings showing improvements in cognitive function, blood sugar control, body weight, and cholesterol levels reinforce the role of almonds as a superfood. Their versatility and convenience make them an easy addition to everyday eating habits, while also providing important nutrients that support overall well-being,” said Ritika Samaddar, Regional Head, Department of Clinical Nutrition and Dietetics, Max Healthcare.

“Inflammation and oxidative stress are associated with cognitive decline. Our study found those in the almond group had lower levels of both, along with higher levels of a protective antioxidant (Vitamin E), compared with the control group,” said Dr. Seema Gulati, lead researcher of the study and Head of the Nutrition Research Group at the National Diabetes, Obesity and Cholesterol Foundation in New Delhi.
