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.

Magnesium has become one of the most talked-about nutrients in the supplement space, especially among people looking to improve sleep, reduce stress, and support brain health. While experts consistently stress that magnesium-rich foods should be the first line of defense, supplements are often recommended when dietary intake falls short, provided they are taken after consulting a doctor.
Magnesium plays a critical role in brain function and overall health. It is involved in more than 300 enzymatic processes in the body, influencing everything from nerve signalling and muscle function to bone strength and sleep regulation. But not all magnesium supplements are the same, and choosing the wrong form could mean wasting money or dealing with unwanted side effects.
In an Instagram video published on February 2, neuroscientist Robert WB Love, who focuses on brain health and Alzheimer’s disease prevention, explained the differences between commonly available forms of magnesium. He also stressed why women above 50, in particular, should take magnesium intake seriously.
According to Love, magnesium is essential for maintaining a healthy brain and body. He warned that when the body does not get enough magnesium through food or supplements, it compensates by pulling magnesium from the bones.
“Women over 50, listen up,” he said in the video. “If you don’t eat enough magnesium-rich foods or take a magnesium supplement to get the right amount, your body will literally steal magnesium from your bones to use in vital processes throughout the body.”
This, he explained, is why consistent magnesium intake is not just important for brain health but also for protecting bone strength as women age. Ensuring adequate magnesium through diet and supplementation can help support both cognitive function and skeletal health.
Magnesium citrate is one of the most widely available forms, largely because it is inexpensive. However, Love described it as a low-quality option for brain health.
“It’s hard to absorb and can upset your stomach,” he explained, adding that many people experience digestive discomfort after taking it. Because of its poor absorption, magnesium citrate may not deliver meaningful benefits to the brain, making it a less effective choice overall.
Magnesium glycinate, according to the neuroscientist, is one of the better options available. It is well absorbed, gentle on the stomach, and beneficial for the brain and the rest of the body.
He also highlighted its positive impact on sleep and stress levels. Many people report sleeping better when they take magnesium glycinate before bedtime, making it a popular choice for those struggling with restlessness or anxiety.
Magnesium threonate stands out because of its ability to cross the blood-brain barrier. Love explained that this allows it to directly enter the brain, making it the most potent form for cognitive health.
However, it is more expensive and harder to find than other forms. Despite this, he noted that both magnesium threonate and magnesium glycinate are excellent options for brain support.
Love also pointed to magnesium taurate, a form that does not get much attention. According to him, it is particularly beneficial for heart health.
“What’s good for your heart is good for your brain,” he emphasised, suggesting that magnesium taurate may offer indirect brain benefits by supporting cardiovascular function.

Have you ever had a weird craving that you were not able to justify? These are not just night-time craving that happens because you spend the time studying. These cravings happen at anytime, however, even after you ate the snack, you did not feel better. If so, then there could be an underlying reason for it, including a reason which could adversely impact your health. Dr Arush Sabharwal, Bariatric and Metabolic Surgeon at SCOD Clinic explains that these cravings often relate more to the body's energy and nutrient consumption that the food item by itself.
"The irregularity in meals, a poor diet, lack of water, and inadequate amount of proteins and fibers in food can disrupt the metabolic balance in our body and increase hunger peaks. If the nutrition in our diet is not good in terms of variety and consistency, our body might send out hunger signals even if there is an adequate calorie content," says Dr Sabharwal.
Furthermore, Dr Mustkim Khan, Khan Laparoscopic Surgeon and Proctologist at SCOD Clinic says, "Digestive health is a major factor that plays a role in nutrient assimilation and the interpretation of hunger cues. Deficient digestive activity, even with regular food intake, can result in nutrient assimilation difficulties, and the body responds by creating cravings for food."
A sudden craving for sweet or creamy chocolate could be related to magnesium. As per Nebraska Medicine, chocolate bar, especially dark chocolates contain magnesium, iron and fiber. If you are anemic, or have low iron, you could be craving a chocolate, because your body is actually telling you to consume iron. While chocolate has a small amount of iron, it is easily accessible. Furthermore, craving chocolate could also indicate a magnesium deficiency, which is related to energy production and mood regulation.
When you are craving something salty, it is not only because you want something savoury, but could be because you are dehydrated.
There are several studies that show people who are on medications waste salts, known as diuretics. This is why people may crave salt. However, only some diuretic medications cause this, the main reason could be dehydration. When you sweat a lot, your body loses both water and sodium, this also leads to you craving something salty. The best thing to do would be to drink water or electrolyte solutions, approved with the World Health Organization (WHO), and your doctor.
All of them sound weird, however a condition called pica, could actually make you crave all this. This happens when your body craves non-food items. Mayo Clinic suggests that craving ice, called pagophagia, is often related to low iron, this could be with or without anemia. Several studies, including a 2010 study by Y Khan, also revealed that pica is an unusual condition where patients develop cravings for non-nutritive substance, usually linked with iron deficiency.
Craving food high in carbohydrates like pasta, or bread could be because you do not sleep well. These food items are a quick source of energy, and when you do not get enough sleep, your body craves for energy, usually the fastest source.
This indicates that you may be lacking iron and zinc. Studies have shown that red meat, while recommended to not be consumed often, could make a healthy diet. Some studies have shown benefits with a small amount of red meat.
While one reason your body craves certain food item is related to lack of nutrition, there could be other factors too, including:
As per Dr Khan, sedentary lifestyle combined with irregular eating habit could lead to disturbances in gut function and bowel regularity. "This could interfere with the proper and efficient processing of food consumed. It could impact the appetite as well. Indigestion could lead to a feeling of heaviness, bloating, etc., after eating food," he explains.

California mushrooms poisoning has led to four deaths and three people who required liver transplant. This happened after people consumed the death cap mushroom that is proliferating in California following a rainy winter.
The California Department of Public Health has urged people to avoid mushroom foraging altogether as death cap mushrooms could easily be confused with the safe and edible ones.
Since November 18, 2025, there have been more than three dozens cases of death cap poisoning. This included three people getting liver transplants, confirmed the health department. Among the cases, four were also reported to be dead. Some of whom sought medical attention suffered from rapidly evolving acute liver injury and liver failure. Other patients were required to be admitted in intensive care units. The patients age ranged from 19 months to 67 years old.
The death cap mushroom is the most poisonous mushrooms in the world. It is part of a small group of mushrooms that contain amatoxins, which are highly potent compounds and cause 90% of fatal mushroom poisoning globally. They could be found in city parks, forests, and often under oak trees.
Dr Craig Smollin, medical director for the San Francisco Division of the California Poison Control System tells PBS News that in a year, there are between two to five death cap poisonings.
"The main thing this year is just the magnitude, the number of people ingesting this mushroom," Smollin said. "Having almost 40 is very unusual."
With warm temperature along with early rains, a 'super bloom' of death caps in California could be seen.
Experts point out that eating even a small amount could be fatal. The confusing part is that the color is usually not a reliable way to detect toxicity. Furthermore, whether the mushroom is consumed raw, dried or cooked, does not make a difference.
Speaking to San Francisco Chronicle, Laura Marcelino, 36, said that her family in the Northern California town of Salinas gathered mushrooms that looks like the ones she and her husband used to forage in their native Oaxaca. "We thought it was safe".
However, the next day, her husband felt dizzy, but Marcelino was fine. They ate the mushrooms again, heating them up in a soup with tortillas. Her kids do not like mushrooms, so they were safe, as they did not have any. The next day, she and her husband became ill with vomiting, and stayed home form work.
Marcelino spent five days in a hospital, while her husband underwent a liver transplant.
In an email response to The Associated Press, the US Poison Centers said that the cases of mushroom exposure have increased, and not just the death cap. This increase was noted from September through January by 40% from the same period in the previous year. Exposure do not always result in illness or poisoning.
Experts point out that early symptoms could go away within a day, but serious to fatal liver damage can still develop within 2 to 3 days
