Ozempic works by mimicking the hormone GLP-1, which suppresses hunger and regulates blood sugar levels. All semaglutide medications work like that. These drugs are great for those trying to shed extra pounds in their body, however, there's a catch. All of these blockbuster weight loss drugs are synthetic and not sustainable in the long run. But wait, what if I told you that researchers have found a component in your everyday breakfast that can do just the same?
Researchers also tested several types of dietary fibre, including dextrin, pectin, resistant starch, and cellulose. However, none of these fibres showed the same impact on weight reduction or fat loss as beta-glucan, despite significantly altering the gut microbiome. "We know that fibre is important and beneficial; the problem is that there are so many different types of fibre," explained Frank Duca, a biomedical scientist from the University of Arizona. The study aimed to determine which type of fibre is most effective for weight loss and glucose regulation, providing valuable insights for consumers and the agricultural industry.
Dietary fibre is a plant-based nutrient found in whole grains, fruits, and vegetables. It serves as the primary energy source for beneficial gut bacteria, playing a vital role in digestive health. Despite its importance, less than 5 per cent of people in the US consume the recommended 25–30 grams of fibre per day. A high-fiber diet is known to be protective against weight gain. Foods rich in fibre tend to have lower energy density, meaning they provide fewer calories per gram of food. This allows individuals to consume the same volume of food while reducing their caloric intake. Additionally, fibre-rich foods are often bulky and filling, promoting satiety.
Soluble fibre, such as beta-glucan, forms a gel-like substance in the digestive tract, slowing stomach emptying and extending the feeling of fullness. This delayed digestion also results in a slower absorption of sugars, helping to maintain stable blood sugar levels and prevent insulin spikes, which have been linked to obesity and an increased risk of diabetes.

Participating in ultra-marathons can cause damage to your red blood cells' flexibility and hamper their oxygen-carrying capacity, a study suggests.
A study published in the American Society of Hematology’s journal Blood Red Cells & Iron notes that extreme forms of exercise may harm, rather than support, overall health.
In the case of ultra-marathons, runners experience breakdown of normal red blood cells during races. Over time, their red blood cells become less flexible and potentially reduce their ability to efficiently carry oxygen, nutrients and waste products throughout the body.
Travis Nemkov, associate professor in the department of biochemistry and molecular genetics at the University of Colorado Anschutz and the study’s lead author said of the results: “Participating in events like these can cause general inflammation in the body and damage red blood cells.
“Based on these data, we don’t have guidance as to whether people should or should not participate in these types of events; what we can say is, when they do, that persistent stress is damaging the most abundant cell in the body.”
Red blood cells transport oxygen and waste throughout the body and must be flexible enough to squeeze through small blood vessels. When red blood cells become inflexible or rigid, they lose their ability to deform and navigate through the body's smallest vessels, leading to impaired oxygen delivery, blockage of blood flow, and rapid destruction by the body's filtration system.
This can lead to low hemoglobin and anemia which can pave the way for diseases like Sickle Cell Disease (SCD), thalassemia, hereditary spherocytosis, and, in some cases, the "storage lesion" of blood in transfusion banks.

Hemoglobin is the oxygen-carrying protein in red blood cells. Adequate hemoglobin levels are essential for keeping organs and tissues properly supplied with oxygen. Without enough of it, the body begins to struggle to meet its basic energy needs.
Low hemoglobin is usually identified through a blood test. It is most often measured as part of a complete blood count (CBC), which checks different components of the blood, including red and white blood cells and platelets, as per Healthline.
While exact reference ranges can vary slightly between laboratories, healthy adult hemoglobin levels usually fall within the ranges listed below. These values are different for babies, children, and teenagers:
Any reading below these ranges in adults is considered low hemoglobin and suggests that oxygen delivery in the body may be reduced, as per Mayo Clinic.
Low hemoglobin is not always an emergency. In many cases, it develops gradually and can be managed with treatment. That said, very low levels can be dangerous. A hemoglobin level below 5.0 g/dL has been linked to serious complications, including heart failure and even death. Levels under 6.5 g/dL may be considered life-threatening and require urgent medical care.
What Causes Low Hemoglobin?
One of the most common reasons for low hemoglobin is anemia. Anemia occurs when the body does not have enough healthy red blood cells. The most frequent type is iron-deficiency anemia, which develops when the body lacks enough iron to produce hemoglobin.
Other forms of anemia include pernicious anemia, which occurs when the body cannot properly absorb vitamin B12, and hemolytic anemia, where red blood cells are destroyed faster than they are produced.
Low hemoglobin can also be caused by:
Treatment depends entirely on what is causing the low hemoglobin. A healthcare provider will first identify the underlying reason before recommending treatment. Possible treatment options include:
If a long-term illness is responsible, managing that condition becomes the key part of treatment, alongside monitoring hemoglobin levels regularly.
Researchers from Denmark and Australia have discovered a new virus in the gut that can contribute to the development of colorectal cancer in the body, one of the leading causes of death in the world.
Using genetic sequencing, researchers studied the gut bacteria of cancer patients in a large Danish study and found that Bacteroides fragilis, an anaerobic, gram-negative, pleomorphic to rod-shaped bacterium, often carried a bacteriophage — a virus that infects and reproduces inside bacteria.
This allows it to produce a toxin (BFT) in the colon, promoting chronic inflammation, cell proliferation and tumor growth in the region.
People with colorectal cancer were twice as likely to have this bacteriophage in their gut bacteria. The virus also appears to be previously unknown and does not match any recorded type so far.
Although the first finding came from a small group, it was later confirmed in a larger study of 877 people with and without colorectal cancer. The results suggest that viruses hiding inside B. fragilis may play a role in cancer development.
Microbiologist Flemming Damgaard, from Odense University Hospital in Denmark: "It has been a paradox that we repeatedly find the same bacterium in connection with colorectal cancer, while at the same time it is a completely normal part of the gut in healthy people.
"We have discovered a virus that has not previously been described and which appears to be closely linked to the bacteria we find in patients with colorectal cancer."
Colon cancer develops from polyps in the colon or rectum, often taking years to show symptoms. The cancer begins when small growths called polyps form on the inner lining of the colon or rectum. Over time, changes in the DNA of these cells can cause the polyps to become cancerous.
As abnormal cells multiply, they replace healthy cells and eventually form a mass known as a tumor. This process develops slowly, often taking up to ten years for a precancerous polyp to turn into cancer and begin showing symptoms.
The American Cancer Society notes that colorectal cancer impacts around 1.9 million people every year.. In India, it is the fourth most common cancer among both men and women. In 2022, there were 64,863 new cases and 38,367 deaths.
Projections suggest that incidence will continue to rise by 2026, reflecting both lifestyle changes and improved detection.
Colon cancer can be difficult to detect because it often develops without obvious symptoms. According to experts , these are the three things you should do to protect yourself:
1. Timely risk screening
2. Knowing your cancer family history
3. Acting on early symptoms
Colon cancer rarely announces its presence with dramatic symptoms. More often, it whispers — through changes in bowel habits, subtle abdominal discomfort, or unexplained weight loss.
Some of the most commonly missed early signs include:
Persistent changes in bowel habits, especially if they last more than a few days, must be taken seriously. Narrow or ribbon-shaped stools may indicate a tumor partially blocking the colon.

Schizophrenia is a severe, chronic brain disorder that can lead psychosis, hallucinations, delusions, disorganized thinking and reduced emotional expression. It can affect how a person thinks, feels and behaves, making it hard to distinguish reality.
The chronic neurological condition affects less than one percent of the global population and typically emerges in late teens to early thirties, requiring lifelong treatment.
However, Canadian researchers have now pointed towards the placenta as a possible source of early indicators of schizophrenia risk.
According to the scientists, the placenta can "record" what happens during pregnancy and can reflect both healthy and unhealthy conditions for the baby, a phenomenon known as the placenta-brain axis.
The theory suggests that when the placenta is negatively affected, brain development may also be harmed in both the short and long term and increase the baby's risk of developing the lifelong condition.
Multiple large-scale studies have found that in pregnancies where babies are born with low birth weight, certain genetic markers in the placenta are altered. These changes are strongly linked to a higher risk of schizophrenia and other developmental problems, such as autism and learning difficulties.
There is also strong evidence that using cannabis during pregnancy can harm a baby’s brain development and increase the risk of schizophrenia.
However, while cannabis use during pregnancy is known to be linked to low birth weight, it is still unclear whether cannabis exposure affects the same placental genetic markers associated with schizophrenia.
In schizophrenia, the brain experiences structural and chemical changes that disrupt normal thinking, emotions, and behaviour. Research shows that people with schizophrenia often have reduced grey matter volume, particularly in areas involved in memory, emotion, and decision-making, like the hippocampus and prefrontal cortex.
Abnormalities in neurotransmitters, especially dopamine and glutamate, also play a key role, leading to symptoms such as hallucinations, delusions, and cognitive difficulties. Connectivity between different brain regions may become impaired, affecting the brain's ability to process information smoothly.
These changes typically emerge gradually, often beginning in late adolescence or early adulthood, and vary significantly from person to person.
According to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition), schizophrenia is diagnosed based on a set of specific symptoms. Here's the list of core symptoms:
