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.
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.
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.

An absolutely fit and healthy man, 54, a runner too, a non-smoker, non-drinker and off the drugs, suffered a stroke that caused permanent damage to him. This is after he consumed energy drinks. It all started when he suddenly noticed a weakness in his left side of the body. It started with numbness and difficulties with balance, walking, swallowing and speech. This is when his family member rushed him to a nearby stroke clinic.
According to CNN: “His blood pressure was sky high, about 254 over 150 millimeters, yet when you looked at him you’ve never know it, because he looked so well. That’s why we call hypertension the silent killer,” said Dr. Sunil Munshi, a consulting physician at Nottingham University Hospitals NHS Trust in the United Kingdom.
The man was a warehouse worker from Sherwood, Nottingham and the case is published in BMJ Case Reports, with Munshi being the senior author of the paper.
As per Dr Munshi, the patient arrived at the hospital with numbness on his left side. Scans revealed a stroke in the thalamus, a deep part of the brain responsible for balance and coordination.
“His left side was numb, and scans showed he had a stroke in the deeper part of the brain, the thalamus, which explains the unsteadiness,” Dr. Munshi said. The man was admitted, and doctors began aggressive treatment. He required five different medications before his blood pressure fell to 170. Normal adult blood pressure is below 120 over 80 millimeters of mercury. Readings of 180 over 120 or higher qualify as a medical crisis.
Once discharged, the situation worsened. At home, his blood pressure rose again, reaching 220 despite continued treatment. With no clear medical cause, doctors conducted extensive tests. Everything came back negative.
The breakthrough came only when the man casually mentioned his daily habit. To stay alert on long shifts, he drank eight highly potent energy drinks every day, two cans at four separate points. Each can contained about 160 milligrams of caffeine.
Study first author Dr. Martha Coyle noted that some energy drinks contain up to 500 milligrams of caffeine per can. For comparison, tea has about 30 milligrams and coffee about 90. In the United Kingdom, adults are advised to consume no more than 400 milligrams of caffeine a day. This man was taking in more than 1,200 milligrams, about triple the recommended limit. The US Food and Drug Administration gives the same advice.
After he stopped drinking energy beverages entirely, his blood pressure returned to normal within weeks. He is healthy today, but the stroke left lasting effects.
“I obviously wasn’t aware of the dangers,” the man told his doctors. “I have been left with numbness on the left side, in my hand, fingers, foot and toes even after eight years.”
Researchers say the problem extends far beyond caffeine. Many energy drinks contain taurine, an amino acid that can raise blood pressure even more when combined with caffeine. High sugar levels also contribute to blood vessel damage.
“These drinks contain combinations of ingredients that increase blood pressure, affect metabolism and may damage blood vessels,” Dr. Munshi said. The beverages often include ginseng, guarana, theophylline and theobromine, all stimulants that can further strain the cardiovascular system.
Doctors have documented cases of cardiac arrhythmias, hemorrhages and strokes linked to heavy energy drink use. Some young adults combine them with cocaine or methamphetamine, a mix Munshi described as capable of causing “havoc.”
Munshi believes this case should push doctors to ask patients about energy drink use, especially younger individuals presenting with heart issues or stroke-like symptoms. He said the drinks have become more potent over time and may warrant stricter regulation and clearer public warnings.
“We propose increased regulation of energy drink sales and advertising, which are often targeted at younger ages,” he said.

Green tea is healthy. A statement we hear every now and then. It surely is a healthier option, but how healthy is it really? Can everyone drink green tea? Or is it only for some people, while others may have to find alternatives?
Well, first things first, green tea is actually a healthier option, however, a 2024 study published in Chemosphere shows that the tea bags these green teas are sold in expose the consumers to microplastics. This means while green tea in its purest form is healthy, the packaging may actually be harmful. What is even more surprising is that there could actually be certain people who cannot drink green tea. Are you one of them? Let's find out.
Here are the 6 kinds of people who cannot drink green tea. But, worry not, we also have some alternatives for you!
Green tea contains catechins, these are antioxidants that make green tea better than the tea we usually drink. However, they can also irritate your stomach lining and alter acid levels. These catechins increase the production of stomach acids and it could lead to discomfort, bloating, constipation, and could even worsen your acid reflux and ulcers. This is, given that you already struggle with stomach issues.
The best thing to do? Do not consume green tea on an empty stomach. Ensure that you have eaten something before you go take a sip of it.
The same catechins that we talked about earlier could in fact block the absorption of iron in your body. This could cause anemia. In fact, a 28-year-old Lynn Shazeen, who was a Matcha-enthusiast, the purest form of green tea, ended up in the ER due to 'dangerously low iron levels'. The reason? You guessed it right. She drank too much Matcha, as a result, her iron levels went down from 23 to 13.
What can you do instead? Make sure that you are consuming enough iron otherwise. Include vitamin C-rich food in your diet, as they too can help boost iron absorption.
If you are pregnant or a breastfeeding mother, consuming large amount of green tea could affect your baby's health. The caffeine in green tea could increase the risk of miscarriage and the catechins could interfere with folic acid absorption. These two passed to the baby through breast milk could overstimulate the baby.
What can you do? Experts say that new mothers or pregnant women must limit their intakes to no more than 2 cups a day.
If you are someone who does not react well to caffeine, do not drink green tea. Yes, green tea is sold as a healthier alternative, but not because it is caffeine-free, but because the amount of caffeine is less. An 8-ounce cup of green tea has somewhere between 20 to 45mg of caffeine, compared to a cup of coffee that has 95mg.
What can you do instead? Go for non-caffeinated drinks like juices, chamomile teas, or turmeric latte to ditch your Matcha latte.
Like we do not let our kids drink tea; green tea comes under the same category. The caffeine content in it could overstimulate their nervous system. Green tea also contains tannins, which gives it its bitter taste, this could block the absorption of important nutrients and could even make your kid anemic.
What to do instead? You can give your young ones unsweetened milk, or coconut water for some taste. Talk to a nutritionist to ensure that whatever drink you give your kids do not spike their blood sugar levels.
If you have:
Then, it is best to stay away from green tea, as caffeine and tannins could further make your conditions worse.
You can go with herbal tea like chamomile, or lemongrass. They are great alternatives to green tea, and also do not contain any caffeine. You can also add a little cinnamon to make it flavorful.
The alternatives are as followed:
Hibiscus Tea
You can also add a little cinnamon to make it flavorful. While giving up tea could be hard, as the ingredients in it are what makes it addictive, however, the first step is always the harder one. Once you make the first move, which is to find an alternative, all that is left for you is to make it a routine. Voila! You are now healthier.

Weight loss is one of the most discussed health topics today, with countless strategies promising results. Two approaches that have gained attention recently are the use of Ozempic, a medication designed to regulate appetite and metabolism, and the longevity diet, a mindful, whole-food approach aimed at long-term health benefits. But which is truly more effective for shedding pounds and maintaining overall well-being?
We got in touch with Dr. Pratyaksha Bhardwaj, World Record Holder Dietician and Weight Management Expert, who shared her insights on how both methods work and which might suit different individuals.
Ozempic is a prescription medication that helps regulate appetite by acting on the digestive system and influencing metabolic pathways. Dr. Bhardwaj explains, “Ozempic works quickly because it impacts the hormones that control hunger, making it easier for people to reduce their calorie intake.”
This medication is particularly useful for individuals struggling with obesity, insulin resistance, or difficulty maintaining long-term weight loss. “For people who need rapid results or are starting their weight loss journey, Ozempic can provide a significant boost,” says Dr. Bhardwaj.
However, she also cautions that Ozempic requires medical supervision and carries potential side effects. Without lifestyle changes, there is a risk of regaining weight once the treatment stops.
The longevity diet is a plant-focused way of eating that also includes periods of a fasting-mimicking diet to support long-term health. It encourages meals built around vegetables, fruits, whole grains, legumes, and nuts, while cutting back on red meat, packaged foods, and sugary items. The plan is grounded in scientific research and combines everyday nutritious eating with short stretches of a controlled, low-calorie, fully plant-based diet a few times each year.
As per Everyday Health, the diet centres on mostly plant foods, with plenty of leafy greens, seasonal fruits, whole grains, beans, lentils, nuts, and seeds. Olive oil and other healthy fats are used regularly. Protein comes mainly from plant sources, though a few servings of low-mercury fish may be included each week. It calls for limiting red and processed meats, sweets, and refined grains. Some versions suggest keeping meals within a twelve-hour window, such as between morning and early evening.
Unlike Ozempic, the longevity diet is a long-term, holistic approach to eating. Dr. Bhardwaj describes it as “a diet based on whole foods, mindful eating, timing meals according to your circadian rhythm, and creating sustainable metabolic health.”
While results are slower, the longevity diet promotes cellular integrity, reduces inflammation, balances gut health, and builds lasting healthy habits. “This isn’t a quick fix,” Dr. Bhardwaj notes, “but the benefits extend beyond weight loss, supporting overall health for the long term.”
Determining which approach is better depends largely on individual goals, medical history, and lifestyle. According to Dr. Bhardwaj, “Ozempic can provide momentum and jumpstart weight loss, especially for those facing metabolic challenges, but the longevity diet ensures long-term sustainability and better overall health.”
She emphasizes that combining knowledge from both approaches can sometimes be the most effective strategy. “Using Ozempic under medical supervision to get started, while gradually incorporating the principles of a longevity diet, can help people achieve both short-term results and long-term wellness.”
Ultimately, choosing between Ozempic and the longevity diet isn’t about one being universally better than the other, it’s about finding the method that fits your body, lifestyle, and long-term health goals.
