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.

Collagen is essential for maintaining firm skin, prevent premature aging and regulates cell proliferation. While it is usually found in animal sources, many fruits and super foods acts rich sources.
Here are natural collagen rich superfoods, you can consume:
Vitamin C Rich Fruits Guava, Amla, and kiwi help stimulate collagen supporting skin repair and hydration.
Strawberries are rich in polyphenols, reducing oxidative stress, while oranges provide hydration and vitamin for rebuilding the skin. These fruits are catalysts essential for youthful and resilient skin.
Collagen is the perfect ingredient for glowing skin and it is all over the internet–coffee, Collagen is added to coffee by mixing peptides which dissolve easily in hot liquid and powders that give comparatively quicker results. Type 1 Collagen is usually considered the best for skin.
Guavas Better Than Blueberries (Photos: Canva)
Tiny but mighty, eating blueberries not only gives you a sweet taste but also can be extremely beneficial for your entire body.
Extremely rich in antioxidants called anthocyanins, they help with slowing down brain aging. Along with this, the fruit also helps regulates blood pressure and cholesterol levels, overall improving cardiovascular health.
Although they might sound beneficial, they are pricey and inaccessible to a majority of the public.
However, experts have now revealed that guava can provide the body with more benefits than blueberries at half the price.
Why Is Guava Better Than Blueberries?Guavas are living proof that appearances are deceptive. Packed with nearly five times more Vitamin C (about 228mg) and loaded with digestive fibers, this winter fruit is perfectly suited for everyday snacking.
According to Healthline, a single guava can fulfill 12 percent of your recommended daily intake of fiber. A 2025 overview by PubMed also shows that guava leaves have been researched for managing blood sugar levels.
Guavas contain soluble fibers which slow down the digestion and absorption of sugars, preventing sudden spikes in glucose levels. Previous research also shows that regular consumption can help improve insulin sensitivity and lipid profiles, benefiting metabolic health.
With significantly higher Vitamin C content than blueberries, this fruit supports collagen production and gives you brighter skin and protection against premature aging.
While cranberries support urinary tract health by preventing bacterial adhesion and reducing inflammation, strawberries are rich in Vitamin C and folate and help with blood sugar regulation which can help stabilize glucose levels.
After all the environmental damage and aging that you have caused your skin, it deserves the utmost care and protection to rebuild and glow.
While blueberries have been linked to improving skin texture, goji berries are far rich in flavonoids that can neutralize free radicals, boost collagen and protect against UV damage.
Blackberries and raspberries are excellent sources that reduce oxidative stress and inflammation.
Experts recommend incorporating a mix of these fruits in your diet to help repair your DNA, reduce inflammation and prevent chronic conditions.

If you drink 14 drinks per week, the American Cancer Society's peer-reviewed journal Cancer, noted that you have a 25% higher risk of developing colorectal cancer. This also means that you have a 95% higher risk of developing rectal cancer as compared to those who drink an average of one drink per week.
Moderate alcohol intake is measured as seven or less drinks per week, which is associated with a lower risk. However, experts have time and again stressed that there is no safe limit of drinking.
"While the data on former drinkers were sparse, we were encouraged to see that their risk may return to that of the light drinkers,” co–senior author Erikka Loftfield of the National Institutes of Health's National Cancer Institute said in a news release.
The findings come from an analysis of U.S. adults who took part in the National Cancer Institute’s Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Researchers tracked 88,092 participants over a 20 year period and identified 1,679 cases of colorectal cancer during that time.
The data showed a clear pattern. Higher lifetime alcohol consumption was linked to a higher risk of colorectal cancer, with the strongest association seen for rectal cancer. However, the study also offered encouraging news. People who stopped drinking saw their risk decline, highlighting that lifestyle changes can still make a difference later in life.

These findings come at a time of growing concern about colorectal cancer rates, especially among younger people. Earlier this month, the American Cancer Society reported that colorectal cancer has become the leading cause of cancer-related deaths among people under 50 in the United States.
Dr. Ahmedin Jemal, senior author of the report and senior vice president of surveillance, prevention and health services research at the American Cancer Society, said the trend is alarming. He noted that the speed at which colorectal cancer rates have risen among younger adults means it can no longer be considered a disease that only affects older people.

Federal health guidance around alcohol has also shifted. Instead of specifying how many drinks are considered safe, the latest dietary guidelines advise Americans to drink less overall. People with certain health conditions are encouraged to avoid alcohol entirely.
Christopher Kahler, director of the Center for Alcohol and Addiction Studies at Brown University, has previously explained that no amount of drinking is completely risk-free. According to him, health risks increase with higher consumption, which is why current guidelines focus on reducing intake rather than defining a safe threshold.
Taken together, the research reinforces a simple message. Heavy drinking raises cancer risk, drinking less is better for health, and stopping alcohol use can help lower the chances of developing colorectal cancer. With rates rising in younger adults, experts say awareness and prevention efforts are more important than ever.
