Fibre, also known as roughage, is important for your overall health. A person needs fibre for digestion, weight control, to manage cholesterol and blood sugar and to strengthen bones. However, have you ever wondered if there is a right time to consume fibre and its supplements?
How Much Fibre Does One Require In A Day?The recommended daily intake of fibre is 25 grams per day for women and 38 grams per day for men. However, some experts estimate as much as 95 per cent of the population doesn’t ingest this much fibre, and may require fibre supplements due to dietary and age restrictions. On the other hand, ingesting too much fibre, while uncommon for most people, can lead to several uncomfortable digestive and health-related side effects.
No, Fibre can be consumed throughout the day. However, one needs to be careful while consuming fibre supplements. There is limited research which underscores that timing does matter. Many studies suggest taking fibre supplements at meal times can help your body absorb them better and may make them more effective. No matter when you consume the supplements, consistency is the key. Irregular intake of fibre supplements can trigger discomfort like bloating, gas, and changing bowel patterns.
Most research suggests that taking fibre supplements with food can help improve digestion and prevent digestive discomfort. Taking fibre before a meal may help control your appetite and help you feel full. Taking it after a meal may support digestion by bulking up your stool. Some people may experience discomfort when taking a fibre supplement too close to mealtimes. Unless your healthcare provider or registered dietitian says otherwise, consider taking fibre at least 30 minutes before or after eating. You should also drink plenty of water.
Consuming excess fibre or its supplements can result in bloating. Insoluble fibre found in whole grains, vegetables, and nuts, can increase gas production during digestion, causing bloating. It can also cause abdominal pain. Too much fibre can cause the digestive system to work harder than usual, leading to abdominal cramping or discomfort. This occurs as fibre moves slowly through the intestines, increasing the workload on the digestive muscles.
Flatulence (Gas) is another issue. Fibre-rich foods, especially legumes, vegetables, and grains, produce gas as they break down in the intestines. This is a normal byproduct of digestion, but excessive fibre can lead to more gas than the body can comfortably handle.
Soluble fibre, found in oats, beans, and fruits, absorbs water, which can lead to overly loose stools or diarrhoea, as excess water may remain in the intestines. On the flip side, an abrupt increase in fibre without enough water intake can cause constipation. Fibre requires water to move smoothly through the digestive tract, so dehydration or insufficient hydration can lead to harder stools.
High-fibre foods tend to be bulkier, and consuming too much can lead to temporary weight gain due to water retention and slower movement of fibre through the digestive tract. Additionally, fibre can make you feel fuller, causing temporary bloating. Excessive fibre intake can cause a blockage in the intestines, particularly in people with Crohn’s disease or other inflammatory bowel conditions. Since fibre isn’t fully broken down, it can accumulate, potentially causing an obstruction.
Fibre helps slow down the absorption of sugar, leading to more stable blood sugar levels. However, too much fibre may lower blood sugar too drastically, which is a concern for people with diabetes who may be monitoring their blood sugar levels closely.

Intermittent fasting has built a reputation as a modern shortcut to weight loss. Social media, wellness blogs, and celebrity endorsements have helped position it as more effective than simply eating less. But a large scientific review now suggests the reality is far less dramatic.
Researchers analyzing global evidence found fasting plans do not outperform conventional calorie controlled diets. In fact, the results were only slightly better than not dieting at all.
The analysis examined 22 studies involving adults who were overweight or living with obesity. Participants followed different fasting approaches including alternate day fasting, the 5:2 diet, and time restricted eating. Across the board, weight loss outcomes closely matched traditional dietary advice.
Lead author Dr Luis Garegnani told the Guardian, “Intermittent fasting is not a miracle solution, but it can be one option among several for weight management.” He added, “It likely yields results similar to traditional dietary approaches for weight loss. It doesn’t appear clearly better, but it’s not worse either.”
Participants who followed fasting routines lost about 3 percent of their body weight. Doctors generally consider 5 percent loss clinically meaningful for improving health markers like blood pressure and diabetes risk.
This means most people in the trials did not reach the level where measurable health benefits usually begin.
The review also noted the studies were short term, lasting up to 12 months. So while fasting did produce some reduction, the scale of change remained modest.
Surprisingly, the research found little evidence that fasting improved quality of life more than other diets. Researchers also pointed out that none of the studies actually asked participants how satisfied they were with fasting routines.
Garegnani told the Guardian that many fasting studies are short and often inconsistent in design, making firm conclusions difficult. Given how widely fasting is promoted, he said clarifying expectations is important.
Intermittent fasting involves limiting eating to specific hours or skipping food on certain days. Supporters claim it can boost metabolism, improve brain function, and slow ageing.
Some biological theories do support potential benefits. Dr Zhila Semnani Azad from the National University of Singapore explained that metabolism follows circadian rhythms, and fasting may influence how the body uses fat. Research in animals suggests fasting can improve insulin sensitivity and reduce inflammation. It may also trigger autophagy, a cellular recycling process linked to ageing.
However, she noted that there is no universal definition of intermittent fasting, which makes comparing studies difficult.
Professor Maik Pietzner from the Berlin Institute of Health said the limited weight loss was not entirely surprising. He explained that people often become less physically active during fasting periods, which may offset calorie reduction.
He told the Guardian, “If people feel better on such diet regimens, I wouldn’t stop them, but there’s no robust evidence for positive effects beyond a possible moderate weight loss.”
His research also shows the body tolerates food scarcity very well. Even complete fasting for short periods causes only minor biological changes.
The findings suggest intermittent fasting is not harmful for most people but it is not superior either. Traditional balanced diets remain just as effective for weight management.
In simple terms, fasting works mainly because people eat fewer calories, not because it triggers a special fat burning state.
For those who enjoy structured eating windows, fasting may still be a practical lifestyle choice. But the study reinforces a clear message. Sustainable habits matter more than trendy diet patterns, and no eating schedule replaces long term consistency.

Erythritol sweetener, commonly found in most of the food we consume, whether it is a protein bar or energy drink could be linked to stroke risk. While it is considered as a safer alternative to sugar as a natural sweetener, a study from the University of Colorado suggests it could damage cells in the blood-brain barrier.
The blood-brain barrier is brain's security system that keeps the harmful substance off the limits, while letting in nutrients. Research also suggests that it would lead to serious consequences for heart health and stroke risk.
In the latest study, researchers exposed cells that form the blood–brain barrier to erythritol levels typically seen after consuming a soft drink sweetened with the compound. What followed was a cascade of cellular damage that could leave the brain more vulnerable to blood clots, one of the leading causes of stroke.
The researchers found that erythritol triggered intense oxidative stress, overwhelming cells with unstable molecules known as free radicals. At the same time, it weakened the body’s natural antioxidant defences. This double hit impaired normal cell function and, in some cases, led to cell death.
Damage to blood–brain barrier cells is particularly concerning because this barrier plays a crucial role in protecting the brain from harmful substances circulating in the bloodstream. When its integrity is compromised, the risk of neurological injury rises sharply.
Even more troubling was erythritol’s effect on how blood vessels regulate blood flow. Healthy blood vessels constantly adjust their width—expanding when organs need more oxygen and nutrients, and narrowing when demand is lower.
This process depends on a delicate balance between two molecules: nitric oxide, which relaxes blood vessels, and endothelin-1, which causes them to constrict. The study found that erythritol disrupted this balance by reducing nitric oxide production while increasing endothelin-1 levels.
The result is blood vessels that stay constricted longer than they should, potentially restricting blood flow to the brain. This kind of dysfunction is a known warning sign for ischaemic stroke, the most common form of stroke caused by blocked blood vessels.
The most alarming finding in the study was how body's natural protect against blood clot is disturbed. Under normal circumstances, cells release a substance called tissue plasminogen activator, which is described as a natural 'clot buster', which helps dissolve clots before they become dangerous. However, erythritol could interfere with this protective mechanism and allow clots to persist and cause damage.
Several have shown that people with higher blood levels of erythritol face significantly increased risks of cardiovascular events. In one major study, individuals with the highest erythritol levels were nearly twice as likely to suffer a heart attack or stroke.
However, researchers caution that the experiments were conducted on isolated cells rather than full blood vessels. More advanced models that better replicate human physiology will be needed to confirm the findings.
Erythritol occupies a unique space in the sweetener world. Classified as a sugar alcohol rather than an artificial sweetener, it escaped recent World Health Organization guidance discouraging artificial sweeteners for weight control. Its sugar-like taste has also made it a favorite in “keto-friendly” and sugar-free foods.

Ultra-processed foods (UPFs) have been dominating nutrition debates in recent months, but experts say not all UPFs deserve equal concern. Some may be far more disruptive to metabolic and heart health than others, depending on ingredients and frequency of consumption.
UPFs are industrially manufactured products that typically contain refined flours, industrial seed oils, added sugars, preservatives, emulsifiers and stabilizers. Several studies have linked high UPF consumption to obesity, metabolic disorders and cardiovascular disease. One recent study even suggested that eliminating UPFs could significantly accelerate weight loss, while others have connected them to a higher risk of chronic illness.
Speaking to Fox News Digital, Eric Berg, a Florida chiropractor and health educator known online as "the Knowledge Doc," highlighted five commonly consumed ultra-processed foods that may warrant extra caution.
Ketchup may seem harmless, but many commercial varieties contain significant amounts of added sugar, often in the form of corn syrup. Even when consumed in small quantities, frequent use can steadily increase daily sugar intake.
Over time, this added sugar may contribute to excess calories and disrupt metabolic health. Checking ingredient labels and opting for low-sugar or sugar-free alternatives can help reduce this hidden source of sweetness.
Yogurt is widely perceived as a health food, but flavored versions can be misleading. Many contain added sugars, artificial sweeteners and stabilizers that outweigh their nutritional benefits.
While yogurt itself can support gut health—especially when fermented with beneficial bacteria—experts stress that the health impact depends heavily on sugar content, ingredients and portion size. Choosing plain yogurt and adding fresh fruit or natural sweeteners at home is often a better option.
Soda crackers are often marketed as a light or “safe” snack, yet they frequently contain refined flours, added sugars and unhealthy oils. These refined ingredients are quickly digested, which may trigger blood sugar spikes, particularly when eaten without fiber or protein.
Healthier alternatives include whole-food-based crackers made from nuts or seeds, which offer more fibre, nutrients and longer-lasting satiety.
Candy bars are one of the most obvious examples of ultra-processed foods. They are typically made with refined starches, seed oils and artificial additives while offering little to no nutritional value.
Frequent consumption of such products has been linked by nutrition experts to poorer metabolic health over time. The concern isn’t just sugar, but the combination of unhealthy fats, refined carbohydrates and additives that may collectively strain cardiovascular and metabolic systems.
Interestingly, it’s not the ice cream itself but the factory-made cone that raises red flags. These cones are often ultra-processed, containing refined flours, added sugars, unhealthy oils and artificial ingredients.
When paired with commercial ice cream, the result can be a “double hit” of sugar, unhealthy fats and additives, significantly lowering the overall nutritional quality of the treat.
Experts emphasize that moderation matters, and occasional indulgence isn’t the issue. The real concern lies in habitual consumption of ultra-processed foods that quietly dominate daily diets. Reading labels, prioritising whole foods and being mindful of ingredient lists can go a long way in protecting long-term health.
