Irritable bowel syndrome (IBS) affects an estimated 12% of the U.S. population, causing symptoms such as abdominal cramps, bloating, diarrhea, and constipation. While some individuals experience only mild discomfort, others find their daily life disrupted by the condition. Despite its prevalence, IBS remains complex, with no single known cause.

Doctors and dietitians increasingly advise patients to focus on identifying and avoiding specific food triggers, particularly sugar.

Why Sugar Can Be a Gut Trigger

When you eat sugar, your small intestine breaks it down using specific enzymes. Once processed, the sugar is absorbed into the bloodstream for energy. But for people with IBS, this process can go awry.

Some may lack sufficient enzymes to digest certain sugars, resulting in digestive distress. Others may have altered gut bacteria or hormonal fluctuations that make their digestive system more sensitive. Not all sugars cause issues for everyone with IBS, so identifying personal triggers is a crucial step in managing the condition.

The Worst Offenders: High FODMAP Sugars

Many sugars that worsen IBS symptoms fall into a category known as high FODMAP foods, short for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are carbohydrates that are poorly absorbed in the small intestine and can ferment in the colon, leading to gas, bloating, and other IBS symptoms.

Sucrose (Table Sugar):

Common in desserts, baked goods, and even savory packaged foods, sucrose is made of glucose and fructose. It’s one of the most frequently used sweeteners and a known trigger for some people with IBS.

Fructose:

Found naturally in fruit and added to many sugary beverages and snacks, fructose is another major culprit. High-fructose fruits like apples, grapes, and pears, along with honey and agave, may worsen symptoms. Safer alternatives include citrus fruits, cantaloupe, and berries.

Lactose:

A sugar found in milk and dairy products, lactose requires the enzyme lactase for digestion. Many adults don’t produce enough lactase, which can lead to lactose intolerance—especially problematic for people with IBS.

Are Sugar Substitutes Any Better?

Many people with IBS turn to sugar-free alternatives, but not all substitutes are safe bets.

Sorbitol and Xylitol, often found in sugar-free gum and candy, are known to trigger abdominal cramps and diarrhea in people with IBS. While stevia may be a safer alternative, more research is needed. Even natural sweeteners like honey or agave should be approached with caution due to their high fructose content.

It’s Not Just Sugar: Other Foods to Watch

Sugar isn’t the only food that may cause trouble. Other common IBS triggers include:

• Beans and lentils
• Cruciferous vegetables (like broccoli and cauliflower)
• Onions and garlic
• Gluten
• Chocolate and spicy foods
• Fried or processed foods
• Caffeine and alcohol

An elimination diet guided by a registered dietitian may help pinpoint which of these are problematic.

Could It Be Sucrose Intolerance?

In some cases, symptoms similar to IBS may actually be caused by congenital sucrase-isomaltase deficiency (CSID), a rare genetic disorder. People with CSID lack the enzymes needed to digest sucrose and maltose, leading to symptoms like bloating and diarrhea immediately after eating sugar-containing foods. This condition is usually diagnosed in childhood and can lead to developmental issues if not managed.

Sweet Solutions for IBS Relief

Living with IBS doesn’t mean you have to completely give up sweets, but moderation and awareness are key. Some people find they can tolerate small amounts of certain sugars without triggering symptoms, while others need to avoid them entirely.

Ahead of Holi and Eid, and during Ramadan, when demand of cooking oil spikes for meal preparation, every year, substandard quality items hit the market. This year too this happened and to curb this practice, the Uttar Pradesh Food Safety and Drug Administration (UPFSDA) issued 37 notices for non compliance to sellers selling substandard oil. The Food Safety Department also seized oil worth Rs. 6.43 crore.

The UPFSDA inspected 64 manufacturing units across Uttar Pradesh and seized 4,16,494 litres of suspicious edible oil.

What Is Substandard Oil?

Substandard cooking oil refers to edible oils that are adulterated, improperly refined, reused, or of low quality, often containing harmful compounds due to poor manufacturing, such as high-heat processing or chemical contamination. FSSAI reports have indicated that up to 30.7% of edible oils in some markets are of poor quality or adulterated.

As per a 2024 study published in the International Journal of Biochemistry and Molecular Biology, common oil sources shows that most edible oils are extracted from seeds, while certain fruits such as olives, coconuts, and palm fruits are also used to produce oil. However, adulteration remains a major concern. Oils like Argemone oil, mineral oil, castor oil, karanja oil, olive oil, cottonseed oil, and paraffin oil are often blended with edible oils and ghee. Some adulterated products may even contain toxic substances such as cyanide and banned colouring agents.

Mustard oil and soybean oil are particularly vulnerable to adulteration through the deliberate addition of substances such as cyanide, mineral oil, karanja oil, Argemone oil, and linseed oil—practices that pose serious risks to consumer health and safety. Similarly, sesame oil is frequently mixed with other oils including avocado, olive, canola, walnut, peanut, and perilla oils.

Argemone oil, in particular, is derived from the seeds of the Argemone mexicana plant and is commonly mixed with mustard oil. Its seeds are spherical, blackish-brown, and have a net-like surface, closely resembling mustard seeds, which makes detection more difficult.

What Happens When You Consume Adulterated Edible Oils?

Adulteration, in general, makes edible oils and ghee unsafe for consumption and significantly reduces their nutritional value. According to the Indian Council of Medical Research, many adulterants can cause permanent organ damage. History offers stark warnings: in Spain, the sale of non-edible rapeseed oil falsely marketed as olive oil led to more than 600 deaths in what became known as the Spanish toxic oil syndrome.

Argemone-contaminated oils have triggered major outbreaks in several countries, including a severe epidemic dropsy crisis in New Delhi in 1998. Reported symptoms included retinal haemorrhages, anaemia, kidney dysfunction, and severe protein deficiency. Some adulterated oils may also contain carcinogenic substances such as polycyclic aromatic hydrocarbons (PAHs), increasing long-term cancer risk.

Other adulterants pose additional dangers. Castor oil contamination can cause severe gastrointestinal distress. Mineral oil adulteration is linked to liver toxicity and cancer risk. Cottonseed oil, when improperly blended, increases exposure to high levels of polyunsaturated fats, potentially contributing to obesity, diabetes, and other lifestyle-related diseases. In some alarming cases, soybean and mustard oils have been found adulterated with burnt mobil oil containing polychlorinated biphenyls (PCBs), toxic chemicals associated with liver damage, neurological changes, dehydration, respiratory irritation, and systemic organ harm.

Adulteration can also trigger allergic reactions. If peanut oil is used as an undeclared adulterant, it may cause severe allergic responses in susceptible individuals.

The most concerning aspect is that loose or unpackaged edible oils are more prone to contamination and adulteration. What may appear to be a simple cost-cutting practice can, in reality, expose consumers to life-threatening toxins, chronic disease risks, and irreversible organ damage.

In a world where stress, anxiety and declining mental well-being are becoming increasingly common, many people are looking for simple lifestyle habits that can promote positive mood and psychological resilience.

New research suggests that eating around three servings of flavonoid-rich foods everyday, especially fruits such as blueberries, strawberries, apples and citrus fruits, may be linked with higher levels of happiness and optimism over time.

A large-scale observational study utilized data from the US Nurses Health Study 2026, one of the largest and longest running health studies focused on women. Scientists at Queens University Belfast and Harvard T.H. Chan School of Public Health analyzed the eating habits and mental health of tens of thousands of women aged 60 and over for a period of up to 18 years.

Participants who consumed about three servings per day of flavonoid-rich foods were found to be three percent more likely to maintain sustained happiness over time and about six percent more likely to maintain long-term optimism

According to the authors, greater consumption of particular fruits such as blueberries and strawberries in some instances correlated with an 8-16 percent higher probability of being psychologically well over time.

Although the percentage increments may seem minor, the team of researchers point out that tiny effects at the population level can have a significant impact, particularly when the observation period is as long as almost twenty years.

The results were additionally featured in a press release of the International Blueberry Organization, which stressed the public health impact of regularly eating flavonoid-rich fruits.

Why Are Flavonoids Important?

• Berries (blueberries, strawberries)
• Apples and pears
• Citrus fruits (oranges, grapefruit)
• Tea and red wine

How Does Diet Affect Happiness?

1. Reduced Inflammation: Chronic low-grade inflammation has been associated with depressive symptoms. Flavonoids may help dampen inflammatory pathways in the body.

2. Antioxidant Protection: One of the most dangerous byproducts of metabolism is oxidative stress and the damage it causes to our cells, including neurons involved in emotional regulation. Flavonoids are effective in the neutralization of free radicals.

3. Improved Vascular Function: Better blood vessel function may enhance cerebral blood flow, supporting optimal brain performance.

Surprisingly, the researchers also retained that an individual with higher levels of optimism was more likely to maintain healthy diets over time, hence, the possibility of a "virtuous cycle" mood and nutrition may reinforce one another.

A Simple, Actionable Takeaway

• Blueberries with breakfast
• An apple as an afternoon snack
• Citrus slices in a salad
• A cup of tea in the evening

While research keeps delving into the complex connection between diet and mental health, the takeaway message that emerges is: our diet not only supplies energy to our bodies but it also influences the quality of our mood and outlook on life.

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.

What Is the Mediterranean Diet?

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:

• Fruits and vegetables
• Whole grains
• Legumes and nuts
• Olive oil as the primary fat source
• Moderate fish consumption
• Limited red and processed meats

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.

The Study That Sparked Attention

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.

Why Does Diet Affect Asthma?

• Omega-3 fatty acids from fish, which help regulate inflammatory pathways
• Polyphenols and antioxidants from fruits and vegetables, which reduce oxidative stress
• Healthy monounsaturated fats from olive oil, which may support immune balance

What To Remember

Some previous cohort studies have yielded inconsistent results, and experts concur that randomized controlled trials would produce more reliable evidence.

The Bigger Picture

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.
