Is Raw Milk Worth The Risk? Truth About Raw Milk And Its Potential For Contamination
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.
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.
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.
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.
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.
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.
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.
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.

Women should make sure their diets include enough omega fatty acids, researchers say, after finding unusually low levels of these compounds in female Alzheimer’s patients.
This comes from an analysis of blood samples from both Alzheimer’s patients and healthy individuals, which showed that unsaturated fats, including those rich in omega fatty acids, were up to 20% lower in women living with the disease. So, could an omega-rich diet actually help reduce Alzheimer’s risk?
A major study has shown that women with Alzheimer’s have markedly lower levels of unsaturated lipids, including omega fatty acids, in their blood compared to cognitively healthy women. This points to a potential protective role for these fats in maintaining brain health.
Alzheimer’s tends to affect women more, particularly after 80, though the biological reasons are still not fully understood. To explore differences between men and women, researchers analyzed plasma samples from 841 participants in the AddNeuroMed cohort: 306 with Alzheimer’s, 165 with mild cognitive impairment, and 370 cognitively healthy controls. Using lipidomics, they studied 268 individual lipids per participant and examined how lipid composition varied by sex, while also exploring possible causal links through mediation analysis.
The findings revealed clear sex differences. Three lipid groups were linked to Alzheimer’s in women, but only one in men (p<0.05). In women with Alzheimer’s, lipids rich in highly unsaturated fatty acids, including omega fatty acids, were consistently lower, while saturated fats were higher (q<0.05). Importantly, the impact of unsaturated phospholipids on Alzheimer’s risk was independent of cholesterol, LDL, or apolipoprotein B, suggesting a direct biological effect. Men with Alzheimer’s did not show these lipid changes compared to healthy men.
These results highlight that lipid biology in Alzheimer’s is sex-specific, with women showing a clear loss of protective omega-rich fats. While this does not prove a cause-and-effect relationship, it suggests that omega-rich foods like oily fish or supplements could help reduce risk, though clinical trials are needed to confirm this.
A diet high in omega-3 fatty acids may support brain health and lower Alzheimer’s risk through anti-inflammatory, antioxidant, and neuroprotective effects. The most important omega-3s are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are essential for proper brain structure and function, according to Healthline.
About two-thirds of people with Alzheimer’s in the US are women, notes Harvard neuropsychologist Rachel Buckley, PhD. “Women actually tend to live with dementia longer than men.”
Women are more likely to develop Alzheimer’s due to a mix of biological, social, and cultural factors, including longer life expectancy, hormonal changes after menopause, and differences in education and work experience. The disease can also show up differently in women; some studies suggest tau protein spreads faster in their brains, which may delay diagnosis until later stages, according to Harvard Health.
Recent research has highlighted that the reasons for the sex gap in Alzheimer’s are complex, involving both biology and social factors. Potential contributors include women’s exposure to sex hormones, genes on the X chromosome, the presence of risk factors like hearing loss, the APOE4 genetic variant, and lower cognitive reserve related to education levels.

Magnesium supplements are everywhere. Whether you see it on pharmacy shelves or wellness blogs and social media where influencers who swear by them. You’ve probably heard someone claim that a daily magnesium tablet can help you sleep better, ease muscle cramps, or boost your mood. But do you actually need one, or is this just another wellness trend gone too far?
Magnesium is an essential mineral that plays a crucial role in over 300 biochemical reactions in the body. It helps regulate muscle and nerve function, supports a healthy immune system, builds protein, maintains blood sugar and blood pressure levels, and aids in energy production.
Because the body doesn’t produce magnesium on its own, it must come from external sources such as food or supplements. The recommended daily intake varies: 310–420 mg for adults and 30–410 mg for children, depending on age and sex.
The good news? A balanced diet can easily meet these requirements. Magnesium-rich foods include nuts and seeds, leafy green vegetables, legumes, seafood, whole grains, and meat. Even dark chocolate can help, 100 grams of dark chocolate contains around 146 mg of magnesium.
Most people get enough magnesium from food, but certain groups are more vulnerable to deficiency. These include people with gastrointestinal disorders such as Crohn’s disease or coeliac disease, those with type 2 diabetes, people who consume excessive alcohol, and older adults.
If you’re low on magnesium, you might notice symptoms such as muscle twitches, spasms, fatigue, low appetite, nausea, or an irregular heartbeat. However, the only way to confirm a deficiency is through a blood test prescribed by your doctor, which, in most cases, is covered by Medicare.
Magnesium supplements are often promoted as a solution for muscle cramps, migraines, and insomnia. But do they actually work?
While magnesium deficiency can lead to cramps, most cases of muscle cramps are not due to low magnesium. Research shows limited evidence that supplements prevent cramps, especially in older adults.
The link between magnesium and better sleep is also unclear. Some studies found it helped people fall asleep faster, while others found no significant difference.
When it comes to migraines, evidence is stronger. Studies suggest that taking 122–600 mg of magnesium daily for 4–24 weeks may reduce the frequency and severity of migraines in some people.
In general, magnesium supplements are safe when taken in the recommended amounts. However, too much can lead to nausea, abdominal cramps, and diarrhea, because magnesium draws water into the intestines.
Taking extremely large doses (around 5,000 mg daily) can cause magnesium toxicity, which is dangerous. Always check with your doctor before starting supplements, especially if you take other medications.
Magnesium is available in tablets, powders, and even topical forms like creams and bath salts. While these skin-based products may raise magnesium levels slightly, they’re less effective than oral supplements or food sources.
When buying supplements, check the label carefully. Most tablets contain 150–350 mg of magnesium, but formulations vary widely. Some also include additional nutrients like vitamins B6, C, or D, and minerals like calcium or manganese.
Be cautious with vitamin B6, high intake can cause nerve damage over time. If you already take a multivitamin containing B6, avoid magnesium supplements that also include it.

Milk is one of the most common items found in every household and is considered a wholesome food packed with calcium, protein, and vitamin D.
It plays an important role in maintaining strong bones, building muscles, and supporting overall health. Because of its nutritional richness, milk is often called a complete food. However, it is essential to ensure that the milk you consume is pure and free from adulteration. Contaminated or diluted milk can lose its nutritional value and even harm your health. Fortunately, there are simple methods you can try at home to find out whether your milk is pure or adulterated.
Food adulteration is the intentional act of reducing the quality of food by mixing or replacing it with inferior substances, or by removing essential components. The same applies to milk. While contamination of food can happen accidentally during storage, transport, or distribution, adulteration is done deliberately for profit.
Milk adulteration involves adding materials such as water, urea, detergent, or other chemicals to increase volume or extend shelf life. This practice reduces the nutritional value and can pose serious health risks to consumers.
There are a few simple ways to check for adulteration using common items at home:
Regularly drinking adulterated milk can cause several health issues from short-term stomach discomfort to severe, long-term illnesses. The exact effects depend on what substance has been added, ranging from diluted water to harmful chemicals.
