A recent paper in The Journal of Nutrition reports that there is promising, although still developing, scientific evidence linking regular yogurt intake with a lower chance of developing type 2 diabetes (T2D). These findings supported the Food and Drug Administration’s 2024 decision to permit a qualified health claim for yogurt.

The agency stated that steady yogurt consumption appears to be tied to reduced T2D risk and that the new claim can help guide public messaging to encourage people to eat more yogurt, which also raises intake of nutrients many people lack, such as calcium. To understand this connection more clearly, we spoke with Prof. (Dr.) Supriya Awasthi, Dean and Professor at the School of Allied Health Sciences, Noida International University.

What Is Type 2 Diabetes?

Type 2 diabetes is a long-term condition in which the body does not make enough insulin or does not respond to it properly. This leads to high blood sugar levels that gradually damage nerves, blood vessels, and several organs. It is the most widespread form of diabetes. According to the Mayo Clinic, it can often be delayed or prevented by staying active and maintaining a healthy weight.

Yogurt, a simple and widely consumed dairy food, has attracted attention for its possible protective effect. Fermented foods like yogurt contain helpful bacteria known as probiotics. These bacteria support gut health. Research on the gut is still progressing, but scientists now believe the balance of gut bacteria may affect many health concerns, including obesity and diabetes.

Since type 2 diabetes is one of the most common lifestyle-related disorders worldwide, experts continue to study how daily food choices shape its risk. But can a weekly serving of yogurt truly matter? Dr Supriya said that it can, especially when yogurt is part of an overall balanced eating pattern.

Yogurt And Diabetes Type 2

Yogurt offers probiotics that help keep the gut microbiome in good condition. A healthy gut environment supports better metabolism, lowers inflammation, and improves how the body handles glucose. Ongoing inflammation and poor gut balance are well-known contributors to insulin resistance, which is the driving factor behind type 2 diabetes. According to Dr Supriya, regular yogurt intake may ease these problems and help the body manage blood sugar more effectively.

She also explained that yogurt’s protein content and naturally low glycemic index offer added advantages. She said, “Protein keeps you satisfied longer and helps curb sudden cravings. Foods with a low glycemic index do not raise blood sugar quickly. This can help prevent spikes in insulin and reduce the chances of developing insulin resistance over time.”

Several studies show that people who include plain or low-fat yogurt in their weekly meals tend to manage their weight better, which is an important part of lowering diabetes risk.

Is Yogurt Bad For Diabetic Patients?

Yogurt is not harmful for people with diabetes, but choosing the right kind is essential. Many flavored or sweetened yogurts contain large amounts of added sugar, which can raise the risk of diabetes complications. The best choices are plain, unsweetened, low-fat, or Greek yogurt. These provide strong nutritional value without unnecessary sugar. Adding fruits, nuts, or seeds can improve taste in a healthy way.

Dr Supriya said, “While yogurt can support better metabolic health, it should not be viewed as a cure on its own. Its benefits are strongest when combined with a healthy routine that includes regular physical activity, weight control, fiber-rich meals, and limited sweets.” Even so, having yogurt two to four times a week may help maintain steadier blood sugar and lower long-term risk for type 2 diabetes.

Eating yogurt each week can be a simple and useful step in a diabetes-prevention plan. Its probiotics, protein, and gentle effect on blood sugar make it a valuable food for metabolic wellbeing. By choosing plain, low-sugar varieties and pairing them with healthy lifestyle habits, people can take a small but meaningful step toward lowering their chances of developing type 2 diabetes.

The meningococcal B vaccine (4CMenB) is completely ineffective in preventing gonorrhea -- a sexually transmitted infection (STI) --, especially among high-risk groups like gay and bisexual men, according to the results of the world’s largest randomized control trial (RCT).

Gonorrhea is a common bacterial STI caused by the bacterium Neisseria gonorrheae, and is transmitted through unprotected sex.

Even as antimicrobial resistance in gonorrhea has increased rapidly in recent years, Australian researchers explored the efficacy of 4CMenB against the disease.

The large randomized, placebo-controlled trial involving 587 gay and bisexual men showed that the risk of gonorrhea incidence remains essentially the same even after vaccination.

“Across both arms, the gonorrhea incidence was virtually the same -- at around 48 per cent per year, indicating very clearly that the vaccine had no effect on preventing gonorrhea,” said Professor Kate Seib, from Griffith University, in Australia, who led the trial.

In light of the study, the researchers stressed the need to explore other options to combat gonorrhea, such as condoms and regular testing.

The 4CMenB Vaccine

While meningococcal disease (caused by Neisseria meningitidis) and gonorrhea (caused by Neisseria gonorrhoeae) are distinct infections, both are caused by Neisseria bacteria, which share 80-90 percent genetic material.

The bacterium N. meningitidis primarily causes meningitis and septicemia, and observational studies have shown that meningococcal B (MenB) vaccines such as the 4CMenB offer 33-40 percent cross-protection against gonorrhea.

However, the latest study, presented at the Conference on Retroviruses and Opportunistic Infections in Denver, US, found no protection against gonorrhea.

The study “provides strong evidence that the 4CMenB meningococcal vaccine is not effective at preventing gonorrhea in gay and bisexual men who are at high risk of contracting it,” Seib said.

According to the US National Institute of Health, the 4CMenB vaccine is a highly effective, protein-based vaccine designed to protect against invasive meningococcal disease (IMD) serogroup B.

Approved in over 50 countries, it offers 71-95 percent effectiveness in infants and 100 percent in adolescents.

What Is Gonorrhea

Gonorrhea is a common STI, and sexually active people of any age can get the disease and pass it on to partners, and even to their baby during childbirth.

Gonorrhea is the second most common STI caused by bacteria, just behind chlamydia.

As per data from the World Health Organization (WHO), in 2020, there were an estimated 82.4 million new infections among adults globally.

The NIH noted that nearly 1 million new gonorrhea infections occur in the United States every year. About half of these infections occur in people ages 15 to 24.

The symptoms of Gonorrhea in men include:

• White, yellow, or green discharge from the penis
• Pain or burning (possibly severe) when peeing
• Testicular pain and swollen testicles.

Notably, the condition also occurs in women, but up to 50 percent of them won’t experience symptoms. This increases the risk of spread to other partners.

• Common symptoms in women include:
• Unusual vaginal discharge (white or yellow).
• Pain in your lower abdomen or pelvis.
• Pain during sexual intercourse
• Pain when you pee
• Bleeding between periods

A new study suggests that drinking sugary drinks can increase anxiety, among other mental issues, in adolescents by 34 percent.

Sugary drinks are known to be more harmful due to their low fiber, protein, or fat, which typically slow down digestion in solid foods. This means liquid sugar gets into your bloodstream very quickly, causing a sudden jump in blood sugar and insulin levels.

Hyper-fast intake of such drinks can also make it hard for your liver to process the sugar, especially the fructose part. n large amounts, fructose turns into fat in your liver. This buildup of fat is linked to metabolic problems that lead to Type 2 diabetes.

Apart from this, a Bournemouth University, UK literature review analyzed people aged between ten and 19 who drank fizzy drinks, colas, sweetened fruit juices, sweetened milk drinks, energy drinks, and sweetened tea or coffee and found multiple links between the beverages and anxiety diagnosis.

The gut-brain axis — the connection between the brain and the gut — may help explain the link between sugary drinks and anxiety. But gut health is influenced by many factors, including diet, stress, and sleep, which are also linked to anxiety.

Overall, the study suggests that cutting back on sugary drinks could help support teenagers’ mental health. While many studies have looked at how reducing sugary drinks improves physical health, more research is needed to see if it also benefits mental health.

WHO Asks Countries To Tax Sugary Drinks

The World Health Organization is asking countries across the world to increase taxes on sugary drinks and alcohol to reduce cases of chronic conditions such as Type 2 diabetes, obesity, heart disease and fatty liver.

In a January 13 virtual conference, WHO Director-General Dr Tedros Adhanom Ghebreyesus said: "Health taxes have been shown to reduce consumption of these harmful products, helping to prevent disease and reduce the burden on health systems.

"At the same time, they generate an income stream that governments can use to invest in health, education and social protection."

According to a recent report on sugar-sweetened beverages taxes, at least 116 countries tax sugary drinks, including sodas or carbonated canned drinks, but other high-sugar products, such as 100 per cent fruit juices, sweetened milk drinks and ready-to-drink coffees and teas, escape taxation.

Additionally, another report on alcohol taxes shows that even though 167 countries levy taxes on liquor, wine and beer, alcohol has become more affordable or remained unchanged in price in most countries since 2022, as taxes do not get adjusted for inflation and income growth.

How To Cut Back On Sugary Drinks?

Sugary drinks can feel addictive. If you find yourself hooked, try to slowly reduce how much you drink, just like you would with alcohol or tobacco. It helps to plan ahead for when you usually crave a soda.

You can start by mixing plain sparkling water with an equal amount of fruit juice or soda. Then, week by week, slowly reduce the amount of the sugary drink until you're mostly just drinking sparkling water. If it helps, add a little lemon or lime juice for flavor.

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.

What Is Low Hemoglobin?

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:

• Normal Hemoglobin Count in Grams per Deciliter (g/dL) | Normal Hemoglobin Count in Grams per Liter (g/L)
• Adult Males: 13.8–17.2 | 138–172
• Adult Females: 12.1–15.1 | 121–151

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.

Is Low Hemoglobin Ever Dangerous?

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:

• Blood loss or internal bleeding
• Certain cancers, including leukemia, lymphoma, multiple myeloma, and cancers that spread to the bone marrow
• Chronic kidney disease
• Deficiencies of folate or vitamin B12
• Hypothyroidism
• Liver disease
• Poor nutrition or malnutrition
• Myelodysplastic syndrome (MDS)
• Sarcoidosis
• Sickle cell disease and other inherited blood disorders
• Systemic lupus erythematosus
• Thalassemia, a genetic condition that reduces hemoglobin production
• Excess fluid in the body
• Cancer treatments such as chemotherapy and radiation can also lower hemoglobin levels, particularly in adults over the age of 65.

What Does Having Low Hemoglobin Feel Like?

• Feeling dizzy or lightheaded, sometimes fainting
• Muscle weakness
• Ongoing fatigue or low energy
• Pale or washed-out skin
• Frequent headaches

How Is Low Hemoglobin Treated?

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:

• Blood transfusion: If hemoglobin is low due to heavy blood loss, a transfusion may be needed to restore levels quickly.
• Vitamin supplements: When nutritional deficiencies are the cause, iron, folate, or vitamin B12 supplements are often prescribed. Hemoglobin levels usually begin to improve within six to eight weeks.
• Intravenous (IV) therapy: In cases where iron or B12 levels need to be raised rapidly, IV infusions may be recommended.
• Bone marrow transplant: This may be required when low hemoglobin is linked to certain cancers or bone marrow disorders.

If a long-term illness is responsible, managing that condition becomes the key part of treatment, alongside monitoring hemoglobin levels regularly.
