Raw milk, long debated as healthier and nutritious than pasteurized milk by enthusiasts but strongly cautioned against by health practitioners, is now a hot topic in health and wellness circles with the increasing popularity of "natural" and "unprocessed" foods. The dangers surrounding raw milk have been brought to the forefront with the outbreak of H5N1 bird flu, highlighting the risk of contamination in raw milk supplies. All about raw milk, its risks, and the latest science.

What Is Raw Milk?

Raw milk is unpasteurized milk taken directly from cows, goats, or other similar animals. Unpasteurized milk does not go through the heat treatment process meant to destroy harmful pathogens and bacteria. Raw milk proponents say that pasteurization kills nutrients and enzymes. And that might be one false claim after another, as science continues to disprove it.

According to Dr. Meghan Davis of Johns Hopkins Bloomberg School of Public Health, pasteurization does not significantly alter the concentration of minerals or the quality of proteins in milk. In fact, it's a critical step to ensure food safety, particularly for animal-derived products prone to contamination.

Wellness influencers have in recent times advocated for raw milk as the "clean" and "natural" alternative to commercial milk distributed in stores, using claims from improved digestion to the stimulation of the immune system. However, these claims are not scientifically proven. Although raw milk contains antibodies, the amounts are too small to be worth anything for health.

Health Risks of Drinking Raw Milk

Raw milk consumption poses immense risks. It can become contaminated in two major ways:

1. Internal Contamination: Pathogens such as E. coli, Salmonella, and Campylobacter can seep into milk through infected animals.

2. External Contamination: Polluted water, dirt, manure, and contaminated equipment introduce harmful microorganisms.

The infections acquired from raw milk include diarrhea, stomach cramps, nausea, and fever, and severe effects can be experienced by infants, the elderly, pregnant women, and even immunocompromised people. Some other rare but serious diseases like hemolytic uremic syndrome, which may bring about renal failure or stroke, have also been associated with raw milk.

Bird Flu Impact on Raw Milk Safety

Raw milk has become a focal point of the latest bird flu outbreak as preliminary genetic analysis indicates the H5N1 virus, which causes avian flu, may have begun infecting cattle earlier than thought. And the CDC says viral particles have been found in raw milk, which adds one more risk to consuming unpasteurized dairy.

A notable case was with sick and dead cats on a Texas dairy farm that resulted from ingesting unpasteurized milk from infected cows. This presents how unpasteurized milk can be a vector for transmitting diseases.

Legal Status of Unpasteurized Milk

To reduce the risk, the FDA prohibited the interstate sale of unpasteurized milk in the United States. Different states, however, have their respective regulations on this matter:

- 20 states completely banned the sale of unpasteurized milk.

- 30 states allow raw milk sales under specified conditions.

Although these laws exist for protection of public health, many consumers are not even aware of the dangers associated with their consumption.

Why Pasteurization Is Important

Pasteurization destroys harmful bacteria without affecting the nutritional content of milk. Several studies in *Nutrition Today* report that pasteurization does not change the nutrient profile of milk. Pasteurized milk is free from pathogens and, therefore, also a safer alternative for all consumers, especially vulnerable ones.

Myths About Raw Milk Products

It's not just raw milk that's hazardous. Cheese, yogurt, and ice cream with unpasteurized milk carry the same dangers. To anyone tempted by the supposed health value of raw dairy, experts say in one voice: stick to pasteurized, and avoid illnesses like bird flu or salmonella infection.

Should You Drink Raw Milk?

Health organizations, including the FDA, CDC, and American Academy of Pediatrics, strongly advise against consuming raw milk. Beyond the personal health risks, drinking raw milk can also endanger others by increasing the spread of harmful bacteria and viruses.

The emergence of H5N1 in cattle and its link to raw milk calls the world to wake up to better preparedness. Like COVID-19, bird flu has demonstrated vulnerabilities in our food safety systems. The presence of avian flu in raw milk underscores the imperative for strict rules, public education, and investments in the prevention of these diseases.

Could this outbreak push governments and health organizations to step up surveillance and vaccination efforts against zoonotic diseases? The lessons learned from COVID-19 suggest a coordinated approach is essential to prevent future pandemics.

On the other hand, raw milk is far riskier and has far fewer benefits than its apparent healthy, "natural" choice. From bacterial contamination to the allowance of viruses like H5N1, there is evidence that is clear: pasteurization cannot be wished away. As we face new health challenges, it will be science over trends that safeguard public health.

Most people assume that low- or no-sugar drinks are a healthier alternative to regular sodas, but new research suggests that might not be the full picture. A large-scale study presented at UEG Week 2025 found that both sugar-sweetened beverages (SSBs) and low- or non-sugar-sweetened beverages (LNSSBs) are linked to an increased risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD), a condition previously known as non-alcoholic fatty liver disease.

What Is MASLD?

According to the Cleveland Clinic, MASLD—short for metabolic dysfunction-associated steatotic liver disease, is a condition in which extra fat accumulates in the liver. It was previously called nonalcoholic fatty liver disease (NAFLD). Unlike liver damage caused by heavy drinking, MASLD is linked to metabolic risk factors such as obesity, type 2 diabetes, high blood pressure, and high cholesterol. If left untreated, it can progress to more serious liver problems.

What The Study Found

Researchers analyzed data from 123,788 participants in the UK Biobank who did not have liver disease at the start of the study. Participants reported their beverage consumption through multiple 24-hour dietary questionnaires, giving researchers insight into how both sugary and “diet” drinks might affect liver health.

The results were striking: individuals consuming more than 250 grams per day of either SSBs or LNSSBs faced significantly higher risks of MASLD, about 60% higher for LNSSBs and 50% higher for SSBs. Over a median follow-up of 10.3 years, 1,178 participants were diagnosed with MASLD, and 108 died from liver-related causes. Interestingly, LNSSBs, but not SSBs, showed a notable link to liver-related mortality. Both drink types were also tied to increased liver fat.

Understanding MASLD and Its Growing Impact

MASLD occurs when excess fat builds up in the liver, which can eventually lead to inflammation, fatigue, abdominal pain, and loss of appetite. Once considered less common, MASLD has now become the most widespread chronic liver disease globally, affecting more than 30% of the population. It is also emerging as a leading cause of liver-related deaths worldwide.

Lead author Lihe Liu emphasized, “SSBs have long been scrutinized, while their ‘diet’ counterparts are often seen as a healthier choice. Our study shows that both types of beverages are widely consumed, yet their effects on liver health have not been fully understood.”

Liu added, “Even modest consumption of LNSSBs, like a single can per day, was linked to a higher risk of MASLD. These findings challenge the perception that ‘diet’ drinks are harmless and highlight the need to reconsider their role in our diets, especially as MASLD continues to grow as a public health concern.”

Why Both Sugary and Diet Drinks May Harm the Liver

The researchers explained potential mechanisms behind the risks. SSBs, with their high sugar content, can spike blood glucose and insulin, promote weight gain, and increase uric acid levels, all contributing to liver fat accumulation. LNSSBs may affect liver health differently: by altering the gut microbiome, disrupting feelings of fullness, triggering sugar cravings, or even stimulating insulin secretion.

Water Remains the Safest Choice

Experts recommend limiting both sugar-sweetened and artificially sweetened beverages. Replacing either type with water showed a significant reduction in MASLD risk, about 13% for SSBs and 15% for LNSSBs. Simply switching between SSBs and LNSSBs did not reduce risk.

The researchers plan to investigate causal mechanisms more deeply with long-term studies, including randomized and genetic trials. They aim to better understand how sugar and its substitutes interact with the gut microbiome and influence liver disease.

Arterial plaque buildup is one of the biggest drivers of heart disease, yet most people don’t realise how silently it develops. When fatty deposits, cholesterol, calcium, and cellular waste accumulate along the artery walls, they gradually harden and narrow the vessels, a condition known as atherosclerosis. This restricts blood flow, makes the heart work harder, and increases the risk of heart attack and stroke.

While medication and lifestyle changes are standard recommendations, growing research, including a study by the University of Sunshine Coast, Australia, suggests that one everyday food may offer surprising protection: beetroot.

Why Arterial Blockage Happens

Plaque develops over years. High levels of LDL cholesterol damage the artery lining, allowing lipids to stick and form deposits. Inflammation accelerates this process, making the plaque harder and more unstable. When a plaque ruptures, it can trigger a clot that blocks blood flow completely, leading to a heart attack. Because early atherosclerosis has almost no symptoms, prevention becomes essential.

Beetroot: A Natural Artery-Friendly Food

Beetroot has emerged as one of the most heart-friendly foods due to its exceptional nutritional profile. Rich in nitrates, antioxidants, fibre, minerals, and bioactive compounds, it is being studied for its ability to influence blood pressure, reduce inflammation, and possibly slow arterial stiffening, all key factors in preventing plaque formation.

Lowers Blood Pressure Naturally

One of the best-researched benefits of beetroot is its effect on blood pressure. Dietary nitrates in beets convert into nitric oxide, a molecule that helps arteries relax, expand, and carry blood more efficiently. Clinical studies show that drinking beetroot juice can lower systolic blood pressure by 4–10 mmHg within hours. Over time, this improved vascular flexibility may reduce strain on the heart and keep arteries healthier.

Reduces Inflammation, a Key Driver of Plaque

Chronic inflammation is a major contributor to plaque buildup. Beetroots contain betalains, powerful antioxidants with anti-inflammatory properties. Research suggests these compounds may help lower markers of inflammation in the body, ultimately slowing the progression of arterial damage.

May Limit Arterial Stiffness

Arterial stiffness is a strong predictor of heart attack and stroke. Studies have found that beetroot juice can reduce arterial stiffness in both young adults and older individuals. More flexible arteries allow for smoother blood flow, reducing the pressure that contributes to plaque formation and rupture.

Improves Muscle Recovery and Heart Efficiency

Beetroot has been found to improve oxygen efficiency in the body, meaning muscles — including the heart — need less effort to perform the same tasks. This can indirectly protect the cardiovascular system, especially during physical exertion.

Supports a Healthy Cholesterol Balance

The fiber and antioxidants in beetroot may help improve lipid levels by lowering LDL cholesterol and supporting the removal of excess fats. While not a substitute for medication, it complements a heart-healthy diet.

If you're making a smoothie for a health boost, especially for your brain and heart, you might want to leave out bananas. New research suggests that adding a banana to your drink can actually block your body from absorbing key healthy compounds.

Bananas have always been a big favorite for healthy drinks and desserts. You may have seen many healthy smoothie recipes like banana and coffee smoothie, or bananas and berries, being listed along with other healthy food recipes. While it does have many health benefits, how healthy it is with other nutrients involved has been questioned.

Researchers at the University of California-Davis found that bananas interfere with the absorption of powerful nutrients called flavanols. These compounds are fantastic for health, but if you blend them with a banana, you might not get the benefit you're looking for.

Should You Add Bananas In Health Smoothies?

The researchers found that bananas block how well we absorb flavanol. Flavanols are beneficial natural chemicals found in foods like berries, apples, grapes, and cocoa. When you eat enough of them regularly, they are known to help your memory, reduce swelling inside your body, which is called inflammation, and make your blood flow better.

So, why does the banana stop this? The culprit is a specific enzyme, a kind of protein, that is found in high amounts in bananas. It's called polyphenol oxidase (PPO). This is the same enzyme that makes a peeled banana or apple slice turn brown quickly. The researchers found that when PPO mixes with flavanols in the blender, it somehow stops your body from being able to use them. Lead researcher Javier Ottaviani said it was surprising to see how quickly even just one banana dropped the levels of flavanols your body could absorb.

Why Do Bananas Block Nutrients?

The scientists conducted a very clear experiment to figure this out. They had people drink three different things and then measured the flavanols in their bodies, by testing their blood and urine:

The Banana Test

A smoothie made with banana, which is high in the PPO enzyme.

The Berry Test

A smoothie made with mixed berries, which are low in the PPO enzyme.

The Control Test

A plain capsule of pure flavanols, just to see what 100% absorption looked like.

The results were impossible to ignore, the people who drank the banana smoothie had 84% less flavanols show up in their system compared to the people who took the pure flavanol capsule. This clearly proved that the banana was the reason the healthy compounds weren't getting absorbed.

How to Get Your Daily Flavanols?

If you're trying to meet the daily recommendation of flavanols, which is about 400 to 600 milligrams, to help your heart and overall health, you need to be smart about your smoothies.

The main takeaway is to skip the bananas if you're mixing it with high-flavanol foods like berries. If your smoothie already contains ingredients that are low in the PPO enzyme—like berries, pineapple, oranges, mango, or yogurt—then you are maximizing the amount of healthy flavanols your body will actually get. This finding opens the door for more research into how simple acts of cooking or preparing food, like how you brew tea (a major flavanol source), can change the nutrients you absorb.
