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.

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.

Chronic inflammation can cause major diseases like type 2 diabetes, cardiovascular disease, and cancer; thus, while thinking about staying healthy for a long time, it is a very important part of it. The disease is also a silent one that silently harms tissues over time and serves as a major reason for lifestyle conditions like Type 2 diabetes, obesity, and heart disease. Thus, reversing it becomes very important,

Recent study by researchers at Ohio State University, published in the journal Molecular Nutrition and Food Research, is a ray of hope for reversing this issue through dietary changes. The study finds that the drinking of specially formulated tomato-soy juice may reduce inflammation.

How Does Tomato-Soy Juice Fight Inflammation?

This beverage has a couple of potent reasons behind its success in the study against inflammation, namely lycopene and soy isoflavones. Notably, lycopene has antioxidant and carotenoid properties that enable it to neutralize free radicals, which cause cellular damage and fuel chronic inflammation. On the other hand, soy isoflavones possess plant-based nutrients called flavonoids, which have unique anti-inflammatory properties that can copy or modulate hormone signaling to calm overactive immune responses.

How Soy Helps Reduce High BP?

Those taking soy foods around 60–80 grams daily can expect a 28–29 per cent reduction in blood pressure. One hundred grams of soy is roughly equivalent to one cup of cooked beans or lentils, or a palm-sized serving of tofu. Higher soy consumption led to a 19 per cent lower risk of hypertension. Soy foods additionally contain compounds called isoflavones, which may further contribute to blood pressure regulation.

The study shows that tomato-soy juice reduced three major pro-inflammatory proteins in the blood, including interleukin-12 (IL-12p70), interleukin-5 (IL-5), and granulocyte-macrophage colony-stimulating factor (GM-CSF). The drink also lowers tumor necrosis factor-alpha (TNF-α), which is linked with chronic inflammatory diseases.

Are Soya Chunks Good For Gut Health?

Soy foods may support heart health. It is believed to reduce inflammation in blood vessels and improve their flexibility, lowering the risk of heart disease and stroke. Some studies even link soy consumption to a 15 percent lower risk of death from heart disease.

The ‘high-protein’ tag attached to soy products such as soya nuggets, soya chaap, and even soy milk is misleading. As industrially processed foods often contain 80 to 90 percent refined flour, consumers get empty calories that spike blood sugar, disrupt hormonal balance, and fuel inflammation.
