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.

New Delhi: Many people have an irresistible urge to eat something sweet right after a meal. Although this habit is often written off as a preference or some sort of cultural habit, new scientific data suggest that post-meal sugar cravings hint at something serious: a metabolic imbalance. In an interaction with Health and Me, Dr. Aravind Badiger, technical director, BDR Pharmaceuticals, decoded the intricate science behind a sweet tooth, and as per the expert, it is because of a nutrient deficiency.

The Blood Sugar–Insulin Connection

Upon eating a meal high in carbohydrates, blood glucose levels rise. This triggers the release of insulin from the pancreas. If the meal is low in protein and fibre, insulin spikes more quickly, making the blood sugar drop sooner. This drop then triggers a signal to the brain that the body needs quick fuel, often interpreted as a desire for something sweet. This cycle, a rapid rise and fall in blood glucose levels, is known as reactive hypoglycaemia, one of the common reasons people feel the need to have dessert after meals.

The Missing Nutrient: Protein

Protein helps to regulate blood sugar levels after a meal. In addition, adequate protein:

1. Slows digestion and glucose absorption
2. Reduces insulin spikes
3. Improves satiety by elevating GLP-1 and peptide
4. Modulates hunger signals via the hypothalamus

When a meal is low in protein, the body does not get those satisfying signals it is used to receiving. This drives the brain to find sources of energy that work quickly—sugars. In fact, clinical nutrition studies indicate that balanced meals containing at least 20–30 grams of protein reduce post-meal sugar cravings significantly.

The Gut–Brain Axis Influence

Your gut microbiome also plays an important role. Meals high in simple carbohydrates encourage the growth of gut bacteria that thrive on sugar. Evidence shows that low-protein diets shift the balance of gut microbes, which further increases sweet cravings. Thus, the less protein you consume, the more your microbiome may “push” you towards sugary foods.

Emotional and Behavioural Factors

For some people, dessert cravings are psychologically conditioned. The body learns over time to attach a reward to the end of a meal by releasing small amounts of dopamine. But even in such cases, stabilisation of blood sugar through adequate protein intake reduces the emotional component of cravings.

How to Reduce Sugar Cravings After Meals

1. Include 20–30 g of protein in each meal, including eggs, dal, legumes, tofu, fish, lean meats, and dairy products.
2. Choose complex carbohydrates over refined sugars.
3. Add vegetables high in fibre to delay the absorption of glucose.
4. Drink plenty of water – mild dehydration produces symptoms similar to sugar cravings.
5. Sleep 7–8 hours; sleep deprivation increases the hunger hormone ghrelin.
6. Do not conclude every meal with sugar. It is a conditioned response and needs to be broken gradually.

A growing body of research is raising fresh concerns about how deeply smartphones are shaping not just attention spans, but also eating habits and self-image among young people. A recent study published in the Journal of Medical Internet Research has found that excessive and compulsive smartphone use may significantly increase the risk of disordered eating behaviors in adolescents and young adults.

Smartphones Could Turn Into Dependency

The study centers on what researchers describe as Problematic Smartphone Use, or PSU. This is not simply spending long hours on a device, but a pattern marked by psychological dependence, difficulty cutting back, and anxiety when separated from the phone. Unlike casual or necessary screen time, PSU begins to interfere with daily functioning and emotional well-being.

To understand the scale of the issue, researchers analyzed 35 studies involving more than 52,000 participants, with an average age of 17. The findings paint a worrying picture. Young individuals who showed signs of smartphone dependency were more likely to engage in unhealthy eating behaviors. These included emotional overeating, uncontrolled food consumption, and patterns resembling food addiction, even in the absence of a formal diagnosis.

A 7-hour Tipping Point

One of the most striking findings of the study is the identification of a potential threshold. The risk of disordered eating rose significantly among those who used their smartphones for more than seven hours a day. While this may not seem unusual in an increasingly digital world, the study suggests that crossing this limit could have tangible effects on both mental and physical health.

A key factor driving this link appears to be body image dissatisfaction. Constant exposure to curated and often unrealistic images on social media platforms can distort perceptions of beauty and self-worth. Over time, this can lead to unhealthy comparisons and a strained relationship with food.

More Than Screen Time

Importantly, the researchers highlight that not all screen time carries the same risk. The distinction between general use and PSU is crucial. It is the compulsive nature of usage, accompanied by withdrawal symptoms and loss of control, that is most strongly associated with negative outcomes.

The study does not claim that smartphones directly cause eating disorders. Instead, they act as a contributing factor that can amplify existing vulnerabilities, particularly in impressionable age groups.

Wider Mental Health Implications

Beyond eating behaviors, excessive smartphone use has also been linked to anxiety, depression, lower physical activity levels, and reduced productivity. These interconnected issues suggest that digital habits are playing a broader role in shaping overall health.

What Could Help?

Experts suggest that small, consistent changes can make a difference. Setting clear boundaries for screen time, taking regular breaks, and engaging in offline activities such as sports or hobbies can help restore balance. Encouraging mindful use of technology, especially among younger users, is increasingly being seen as an important step in both prevention and intervention.

As smartphones continue to be an inseparable part of daily life, the study highlights the need to look beyond convenience and consider their deeper psychological impact.

Tuberculosis continues to be one of India’s most persistent infectious diseases, but beyond medicines and diagnostics, one factor often decides how well a patient recovers or resists infection in the first place: nutrition. Experts say food and lifestyle are not just supportive elements in TB care. They are central to both recovery and prevention.

Why Nutrition Matters More Than You Think

Tuberculosis and malnutrition are closely linked. The infection weakens the body, reduces appetite, and leads to weight loss, while poor nutrition further lowers immunity, making it harder to fight the disease. Research, including findings published in PubMed Central, shows that undernutrition significantly increases the risk of developing active TB and worsens outcomes during treatment.

Dr Mihir Gangakhedkar explains that TB is both a cause and effect of protein energy malnutrition. In simple terms, poor dietary habits can increase susceptibility, and the disease itself further drains nutritional reserves. To counter this, patients often require nearly 1.5 times their usual calorie intake to regain weight and strength.

What Should TB Patients Eat?

Experts agree that rebuilding the body starts with prioritizing protein and calorie intake.

Dr Sumeet Singhania recommends including protein-rich foods such as eggs, lentils, dairy products, and meat to help repair tissues and regain muscle mass. Dr Gangakhedkar echoes this, adding paneer, curd, and even protein supplements if needed.

Alongside protein, micronutrients play a critical role. Colorful fruits and vegetables provide vitamins A and C, which support immune function and recovery. Whole grains like millets offer sustained energy, which is crucial for patients dealing with fatigue.

Another key takeaway from research is consistency. The RATIONS study in India demonstrated that improving dietary intake among families of TB patients reduced disease incidence by nearly 40 percent. This highlights that nutrition is not just important for patients, but also for those living with them.

Patients are also advised to avoid processed and junk foods, which offer little nutritional value and may slow recovery.

Can Lifestyle Changes Prevent TB?

While TB spreads through airborne droplets, not everyone exposed develops the disease. Immunity plays a decisive role here.

Dr Harsha Jain emphasizes that a strong immune system can significantly reduce the risk of developing active TB. This includes maintaining a balanced diet, engaging in regular physical activity, getting adequate sleep, and managing stress.

Certain habits can increase vulnerability. Smoking damages the lungs and weakens local immunity, while excessive alcohol intake can impair overall immune response. Avoiding these is considered essential.

Environmental factors also matter. Good ventilation reduces the concentration of infectious droplets in the air, and simple practices like covering the mouth while coughing can limit transmission. Early screening, especially for high-risk individuals, adds another layer of protection.

Food, Habits And Recovery Go Hand In Hand

TB treatment is often long and demanding, but recovery is not driven by medication alone. A nutrient-rich diet helps the body heal faster, regain weight, and tolerate treatment better. At the same time, healthy lifestyle choices strengthen immunity and reduce the chances of infection or relapse.

In a country where TB remains widespread, these everyday choices can quietly make a powerful difference.
