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.

Does Timing Matter?

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.

Should You Take It With Food?

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.

What Happens When You Consume Excessive Fibre?

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.

Raw oysters from a single company have been linked to a Salmonella outbreak across multiple states in the US. At least 27 people have been sickened in 12 states and five hospitalised, according to the US Centers for Disease Control and Prevention (CDC). No deaths have been reported so far.

The outbreak has been pinned down to oysters harvested by Little Wicomico Oyster Company from the Little Wicomico River in Virginia. The company voluntarily recalled oysters harvested between September 18 and October 8, 2026. The river was temporarily closed to shellfish harvesting.

Pennsylvania has reported eight infections, becoming the state with the highest number of cases currently, followed by New York with four and Virginia with three. The recalled oysters were distributed to restaurants and retailers in 16 states and Washington, DC, and may have reached other locations.

Oysters That Appear Fresh Can Still Make You Sick

Contaminated shellfish may not always show signs of spoilage. Therefore, the US Food and Drug Administration (FDA) warns - “Food containing Salmonella may look, smell, and taste normal.”

Oysters can become contaminated with harmful bacteria in the environment where they grow. Eating them raw or undercooked means the bacteria may survive and cause infection. Their appearance, smell and taste cannot reliably establish whether they are safe to eat.

The CDC's investigation found that 10 of the 13 people interviewed about their food exposure had eaten raw oysters before becoming ill. Investigators also found that the oysters eaten by several affected people shared a common source, supporting the link to the Virginia harvest area.

Symptoms Of Salmonella Infection

Salmonella infection may cause:

• Diarrhoea
• Fever
• Abdominal cramps
• Nausea and vomiting

Symptoms usually begin within six hours to six days after the bacteria enters your body. Many people recover within four to seven days without treatment, but some may develop severe illness and need medical care.

It can become serious in young children, older adults aged 65 and above and people with weak immune systems. The bacteria can occasionally enter the bloodstream and cause more severe infections.

The CDC has warned that the actual number of infections may be higher than reported because some people recover without seeking medical care or getting tested.

What Should Consumers Do?

The FDA advises consumers not to eat recalled oysters from Little Wicomico Oyster Company, identified by harvester certification number VA-1421-SP, that were harvested from the Little Wicomico River between September 18 and October 8, 2026.

Restaurants and retailers should not sell or serve these oysters. Consumers who have them should discard them or contact the seller. Any surfaces or containers that came into contact with the recalled shellfish should be cleaned and sanitised to prevent contamination.

Anyone who ate the recalled oysters and develops symptoms should contact a healthcare provider and mention the possible Salmonella exposure. Bloody diarrhoea, a high fever, signs of dehydration, or vomiting that prevents someone from keeping fluids down warrant prompt medical attention.

The investigation is ongoing, and health officials are continuing to trace the source and distribution of the contaminated oysters.

An 84-day clinical trial has found that a high-fibre diet improved blood sugar control and reduced body weight more effectively than metformin, the standard first-line diabetes drug, in adults newly diagnosed with both type 2 diabetes and obesity.

Researchers led by Li Y and colleagues enrolled adults aged 18 to 70 with newly diagnosed type 2 diabetes and obesity, according to the study published in Frontiers in Microbiology.

Participants were randomly assigned to either a high-fibre dietary intervention, using two standardised fibre formulations plus dietary guidance, or metformin monotherapy, given according to routine clinical practice. Neither group combined the two approaches.

Researchers tracked diet through food frequency questionnaires and 24-hour dietary recalls, and measured outcomes including HbA1c, BMI, fasting blood glucose, and glucose responses during meal tolerance tests.

Fibre beat the drug on blood sugar and weight

By the end of the trial, the high-fibre group had significantly lower HbA1c and BMI than the metformin group, per the study. Continuous glucose monitoring showed the fibre group had more stable blood sugar overall, with lower average glucose levels and less variability throughout the day.

The fibre group also came out ahead on body composition: lower waist-to-hip ratios, lower leg, trunk and total body fat mass, and lower triglyceride levels compared with the metformin group, the researchers reported.

How the gut bacteria changed

The high-fibre diet reshaped participants’ gut microbiota in ways metformin didn’t. By day 28, the diet had enriched bacteria from the Bifidobacterium and Lactobacillus genera, both generally considered beneficial, while reducing Bilophila wadsworthia, a bacterium linked to gut inflammation, according to the study. Metformin, by contrast, produced little detectable change in gut bacteria.

Several bacterial species associated with fermenting carbohydrates increased specifically in the fibre group. Participants whose acetate levels, a byproduct of that fermentation, rose the most also saw significantly greater drops in HbA1c at both day 28 and day 56, and these participants tended to have distinct gut microbiome profiles at the start of the trial.

Why fibre may work this way

The likely mechanism involves short-chain fatty acids like acetate, produced when gut bacteria ferment fibre. These compounds are thought to boost secretion of GLP-1, the same gut hormone that newer diabetes drugs like semaglutide are designed to mimic, which in turn improves insulin sensitivity and promotes fullness, according to a separate summary of the research by News-Medical.

This isn’t an isolated finding. A separate, smaller crossover trial of 34 newly diagnosed patients, published in a different study, similarly found that early high-fibre nutrition therapy produced rapid improvements in glycaemic control alongside reshaping of the gut microbiome, reinforcing the idea that timing and gut-level changes both matter.

The study’s authors concluded that a high-fibre dietary intervention could be a promising strategy for managing newly diagnosed diabesity, outperforming metformin alone on both blood sugar and weight-related outcomes. They noted that larger trials with longer follow-up are needed to confirm how durable these benefits are and to better understand the exact microbiome mechanisms involved.
