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.

Asthma is usually associated with children. However, a large number of adults are diagnosed with asthma later in life, known as adult, onset asthma. A sharp contrast to childhood asthma, adult cases can be more long, lasting, difficult to control and very much influenced by environmental and lifestyle factors.
Smoking, air pollution, and workplaces are three known risk factors, but experts in the field are opening up the research to include diet as a possible factor that can be changed. New research indicates our diets may play a big role in asthma development and following a Mediterranean diet may significantly lower overall risk by nearly 50 percent.
The World Health Organization estimates that over 260 million individuals globally suffer from asthma.
The Mediterranean diet is inspired by traditional eating patterns in countries bordering the Mediterranean Sea, particularly in places like Spain, Greece and Italy. It recommends eating:
This diet is well known for its cardiovascular benefits and its strong anti-inflammatory and antioxidant properties have prompted scientists to explore its impact on respiratory health.
A large, scale prospective study through the Seguimiento Universidad de Navarra (SUN) Project aimed at finding out if a Mediterranean diet could lower asthma in adults. The project, done by the team at Universidad de Navarra, included data from more than 17,000 university graduates who were tracked for almost 13 years in Spain.
The study participants did not have asthma at the time of registration. Their food intake was assessed through a validated Mediterranean Diet Score (scale of 0 to 9), and incidences of asthma were recorded with the help of follow, up questionnaires.
The study showed that people sticking to the Mediterranean diet the most became adults with asthma 42 percent less than those who followed the diet the least. Additionally, after changing for confounders like age, smoking, physical activity and BMI, this protective effect was still significant from the statistical viewpoint.
The study results were covered by EMJ Reviews and appeared among respiratory research publications, thus attracting the attention of the makers of the next major public health policy measure.
Some previous cohort studies have yielded inconsistent results, and experts concur that randomized controlled trials would produce more reliable evidence.
Though additional research is necessary to be sure, the main idea is increasingly conspicuous: our diet today might determine our respiratory health over the next several years.

FSSAI (Food Safety and Standards Authority of India) has recently shared how one can spot ‘vegetables gone wrong’ before you bring them to your home.
When it comes to health, eating right plays a huge role, and that starts with bringing the right ingredients home. Even though fruits and vegetables are healthy, spotting the signs of spoiled items can be difficult. You could easily bring home bacteria and even dangerous germs like Salmonella, E. coli, and Listeria, according to the US Food Safety department.
Food safety is simple if you keep these key things in mind, according to FSSAI.
Always choose fruits that are firm and solid. If you feel soft spots, it usually means the fruit is starting to rot or was bruised during transport, which invites bacteria. Check the skin for deep cracks or holes, as these are open doors for pests.
For citrus fruits like lemons and oranges, weight is the best secret. If it feels heavy for its size, it is full of juice; if it feels light and "puffy," it is likely dry inside. Finally, don't worry about green spots on the skin; they are often just natural color marks and don't change the sweet taste inside.
Vegetables that grow underground, like carrots, beets, turnips, and sweet potatoes, should feel as strong as the earth they came from. When you pick them up, they should feel heavy and very firm to the touch.
If a carrot feels "bendy" or rubbery like a piece of plastic, it has lost its internal moisture and will be tough and tasteless rather than crunchy.
While it is tempting to grab the biggest vegetable in the pile, the "size secret" is that smaller roots are actually better. Smaller ones are usually younger, which makes them naturally sweeter, more tender, and less "woody" or fibrous when you cook them.
Grapes are very delicate because they stop ripening the moment they are clipped from the vine. To find the freshest bunch, use the "attachment rule": give the bunch a very gentle shake.
The grapes should stay firmly attached to their stems. If they fall off easily, it is a sign the fruit is old and losing its flavor. Next, look closely at the "skeleton" or the stems of the bunch.
You want to see stems that are green and flexible, which proves they were harvested recently. If the stems look brown, dry, or brittle, the grapes will likely be sour, mushy, or lacking that fresh pop.
Since onions are the base for almost every meal, picking a bad one can ruin your entire dinner. A high-quality onion should feel heavy and rock-solid all the way around, especially near the "neck" at the top.
When you give it a gentle squeeze, it should not give way or feel "hollow." If an onion feels soft or squishy, it is likely rotting on the inside where you can’t see it. Also, check for any green sprouts growing out of the top.
Sprouting means the onion is aging and using up its energy, which makes the layers inside lose their crispness and punchy flavor.

Jaggery or, also commonly known as Gurr, is considered the best alternative to white sugar however, more than often, headlines such as "adulterated jaggery has been seized" dominates our daily new.
Despite its popularity and varying uses, it is one of the most commonly adulterated foods mixed with components like baking soda, washing soda or chalk powder. But now the food Safety and Standards Authority of India (FSSAI) shares how we can do a test at home to determine jaggery adulteration with baking soda.
1. Take one 1/4th of a teaspoon of crushed jaggery in a glass container or test tube.
2. Now, add 3 ml of HCL acid, also known as hydrochloric acid, in a container or test tube.
3. If you see bubbles are formed, your jaggery
According to the agency, sodium bicarbonate (baking soda) reacts with acid in the natural sweetener and releases carbon dioxide in the form of bubbles.
FSSAI advises that while home tests can help identify basic forms of adulteration, they are not a substitute for laboratory testing. Only certified labs can conclusively determine the purity of jaggery and detect multiple adulterants at once.
1. Chemical burns in the mouth, throat, and stomach lining.
2. Severe acidity
3. Vomiting
Long-term health risks may involve:
1. Organ failure: Chronic ingestion of industrial dyes and soda puts extreme oxidative stress on the liver and kidneys, which are responsible for filtering these toxins. This can lead to permanent scarring (fibrosis).
2. Hormonal imbalance: Reports from the FDA in 2025 noted that jaggery packaged in low-grade heated plastic releases phthalates and dioxins, which act as endocrine disruptors, affecting reproductive health.
3. Hidden sugar spike: Since white sugar is a common adulterant, individuals with diabetes who consume jaggery as a "safe" alternative may experience life-threatening spikes in blood glucose levels.
