Diet plays a very important role when it comes to your health. There are many people who have to adhere to strict diets because of certain conditions they have. While the basic understanding that we need all kinds of foods to fulfill our body’s needs, sometimes these foods can also cause harm to your body. For example, lactose intolerant people cannot eat or consume any kind of dairy product as their bodies do not have the necessary compounds, known as lactose, to break down dairy foods. Similarly, there are many foods that may be ok for others to consume, but not for people who have digestive issues like IBS. But this new clinical trial may be able to help us know what food we can eat based on our blood test! The blood test, called inFoods IBS, looks for a special type of antibody in the blood. Antibodies are like tiny soldiers that our bodies make to fight off things that could make us sick.

IBS is a very common problem, affecting a large number of people. Many people know that what they eat can make their IBS symptoms worse, but it's often hard to figure out exactly which foods are the culprits. This is because everyone is different, and what triggers one person might not trigger another. Doctors hear from patients all the time, asking for help in determining which foods are causing their problems. So, finding a reliable way to pinpoint those foods is important. This test is attempting to provide that reliability.

How Does This Blood Test Work?

Basically, the test is looking for an antibody called IgG. When the gut reacts badly to a food, it makes more of this IgG antibody. The test checks for reactions to 18 common foods, like wheat, milk, and certain fruits. If the test finds high levels of the IgG antibody for a certain food, it means that food is likely causing problems. Therefore, the patient should try to remove that food from their diet.

Many people with IBS struggle to find relief from their stomach pain and discomfort. This new study looked at whether a special blood test could help. The idea was to see if the test could tell people which foods were making their IBS worse. The results were encouraging. When people changed their diets based on what the blood test showed, about 60% of them felt less stomach pain. This is better than the 42% who felt better when they just tried a general diet change. This shows that the blood test might be a useful tool for people with IBS to get real relief.

How Does This Personalized Nutrition Approach Work?

Many doctors suggest that people with IBS try elimination diets, where they cut out certain foods to see if their symptoms improve. However, these diets can be very hard to follow, because they often require people to cut out a lot of different foods. Doctors are always looking for ways to give patients care that's tailored to their specific needs. In the case of IBS, that means figuring out exactly which foods each person should avoid.

This blood test is a step in that direction. Experts are calling it a move towards "precision nutrition." This means that instead of giving everyone the same diet advice, doctors could use the blood test to create a personalized plan for each patient. While more research is needed, this test brings hope that doctors will soon be able to give much more precise dietary recommendations to those people that suffer from IBS. While this test is yet to be approved by FDA, it could be a world of comfort and ease for people who suffer with IBS.

A recent study has found proof that an autoimmune reaction is triggering certain neurological symptoms seen in some long COVID patients. The study, conducted in healthy mice, found that the mice exhibited symptoms mirroring those of affected patients to some extent.

What is Long COVID?

While it has been a long time since the end of the COVID pandemic, its effects continue to linger even today. Several patients who contracted COVID continue to suffer.

Autoantibodies Behind Long COVID Symptoms?

A US NIH-funded research group, directed by Drs. Akiko Iwasaki and Tamas L. Horvath of the Yale University School of Medicine and Dr. David Putrino of the Icahn School of Medicine at Mount Sinai recently found that autoantibodies could be triggering these neurological symptoms in some long COVID patients.

Antibodies, in a healthy person, help fight infections. In patients with autoimmune diseases, these antibodies target the body’s own tissues. They are called autoantibodies.

The study also discovered that patients who had these autoantibodies are more likely to experience similar symptoms. For example, people with autoantibodies are more likely to face symptoms like loss of taste and smell. They are also more likely to experience nausea and joint pain.

The Mouse Experiment

The researchers conducted the study by transferring purified antibodies from long COVID patients into healthy mice. It was discovered that the mice developed the following changes that resembled the donors' symptoms:

• Antibodies from patients with chronic pain caused increased pain sensitivity

• Antibodies from patients with dizziness caused balance problems

• Antibodies from fatigued patients reduced treadmill endurance

The recent breakthrough in long COVID research has brought the healthcare industry one step closer to personalizing care for those affected.

Dr. Putrino says, “Our study now shows that if you are in a subgroup of Long COVID patients who have autoantibodies circulating in your body, this is a quantifiable sign that you may be a good candidate for these drugs.”

Long COVID Patients More Likely To Develop Heart Diseases

The study finds that cardiovascular diseases were more common among long COVID patients. It concluded that 11.9% of those with long COVID have CVD compared to 6.8% without this condition.

Specifically, it further revealed that long COVID was associated with a higher risk of chest pain and heart attack, but not coronary heart disease and stroke.

There is a growing belief that ‘sugar feeds cancer.’ Because of this, many people think that stopping sugar and carbohydrates completely can starve cancer cells and help defeat the disease. However, the trend may have side effects. This half-truth is becoming dangerous for many patients. This trend is making it even more difficult for patients to cope with the side effects of chemotherapy.

This fact is not entirely unscientific, but it is incomplete. In 1924, the German scientist Otto Warburg found that cancer cells consume more glucose than normal cells. This phenomenon is known as the Warburg Effect.

This finding has subsequently been validated in numerous studies. This is also the reason why cancer cells appear clearly in PET-CT scans. They absorb glucose-like substances more aggressively than normal cells. But this does not mean cancer can be “starved” by reducing sugar in food.

Why The Body Still Needs Glucose?

Glucose is an essential fuel for the human body. The brain, heart, red blood cells, and immune system all depend on it.

If a person completely stops eating carbohydrates, the body starts producing glucose on its own. It breaks down muscles and proteins to make energy. This process is known as gluconeogenesis. This means the cancer cells still receive fuel, but the patient’s body becomes weaker day by day. This condition is described as ‘cancer cachexia.’

In this condition, body weight and muscle mass reduce rapidly. Such patients often cannot tolerate chemotherapy and surgery properly. In some cases, their protein levels and white blood cell counts had dropped too much.

As a result, doctors had to delay treatment, reduce medicine doses, or even stop some treatment cycles. Irony is painful. In trying to starve cancer, patients sometimes end up weakening their own bodies so much that proper treatment becomes difficult.

In my clinic, I see it almost every week. In such a case, a cancer patient walks in visibly frail. She almost had lost several kilograms over the past month. When I asked about her diet, her IT professional son said that she has cut out sugar entirely. The reason behind this was the same reel-based knowledge about sugar and cancer cells. His son strictly follows this half-truth. Due to her weakness, we had to push back her treatment for a few weeks.

What Cancer Patients Should Eat

We simply suggest avoiding foods that rapidly increase blood sugar levels. These include refined sugar, sweets, soft drinks, maida, and highly processed foods. We advise cancer patients to eat complex carbohydrates, whole grains, pulses, vegetables, healthy fats, and enough protein. The best way is not to cut sugar entirely, but to lower the glycemic load.

Will Fasting help?

Some animal studies have shown the benefits of fasting during cancer treatment. However, there is still not enough evidence in humans. For patients who are already weak or losing weight rapidly, long fasting can become harmful.

The Goal Is to Stay Strong During Treatment

Cancer cells use more glucose, but starving the body cannot stop cancer. If you want to help your body, then avoid refined sugar and junk food, but continue eating balanced meals. Because sufficient protein and calories are extremely important. Practising long fasting without medical advice is harmful. The goal should be to keep the body stable and strong, not weak.

The purpose of cancer nutrition is to nourish the patient, not to starve them. Proper nutrition helps the body tolerate treatment and fight disease more effectively. What is needed is to reduce the intake of refined sugar and foods with a high glycemic index, not to declare every carbohydrate an enemy. After all, one cannot win the battle against disease by weakening the body.

A new oral weight-loss drug is showing promising results for people living with obesity or who are overweight. In a phase II clinical trial published in Nature Medicine, participants taking the experimental medication aleniglipron lost up to 12% of their body weight over 36 weeks.

The study included contributions from Robert Kushner, MD, professor emeritus of medicine at Northwestern University and a longtime expert in obesity treatment.

Aleniglipron belongs to the GLP-1 family of drugs, the same class as popular medications such as Ozempic and Wegovy. These treatments help people lose weight by mimicking a natural hormone that reduces appetite, increases feelings of fullness, and helps regulate blood sugar levels.

What makes aleniglipron different is that it comes in pill form. Most currently available GLP-1 medications require injections and often need special storage, which can make them less convenient and more difficult for some patients to access.

Researchers believe an oral option could make treatment easier for many people. Because aleniglipron is a small-molecule drug—meaning it is chemically manufactured rather than peptide-based—it can be produced more efficiently and potentially at a lower cost.

“Aleniglipron is different because it’s a small molecule that can be taken with or without food,” Kushner said. “Most medicines people take every day, from aspirin to blood pressure drugs, are small molecules. That also creates opportunities to combine it with other treatments in the future.”

If further studies confirm its safety and effectiveness, aleniglipron could offer a more convenient alternative to injectable GLP-1 medications and help expand access to obesity treatment.

Why Is GLP-1 Drug A Medical Breakthrough?

Dr Shubham Vatsya explains that it took 20 years of research for scientists to come up with these medicines. This drug underwent proper lengthy trials, and have been approved by the US Food and Drug Administration (FDA), "which is not obtained by giving any bribe".

He also noted that when a person is not able to lose weight, Ozempic and drugs alike give a "head start" to them, along with a hope.

Talking about side effects, he says that every drug has its side effects, this is where a doctor's role comes in.

"Now, the person who is not able to lose weight, if you tell him 'you hit 100 kg bench press', he will break his shoulder. He needs a kickstart somewhere. This is what weight loss drugs allow," he says.

He also points out that the scientists who made GLP-1 agonists got a Nobel Prize, which "cannot be a scam". This is what makes weight loss drugs truly different.

What Are GLP-1 Drugs?

GLP-1 Drugs stand for Glucagon-like peptide 1, a naturally occurring hormones that helps regulate blood sugar and appetite after eating. It was first identified almost 50 years ago and scientists have since uncovered its role in type 2 diabetes.
