Humans became lactase persistent through thousands of years of dairy intolerance. Drinking milk through the pain eventually rewrote human genetics.

The Pasteurized Milk Ordinance allows up to 20,000 bacteria per milliliter in finished pasteurized milk. Here’s what the federal standards actually permit, and how licensed raw dairies compare using the same measurements.

Dairy intolerance doesn’t always extend to raw milk. Many report tolerating it without symptoms, yet the mechanisms behind why have yet to be formally studied.

One amino acid separates A1 and A2 β-casein. That difference determines whether digestion produces BCM-7, an opioid peptide linked to gastrointestinal effects. Here is what the research shows.

Studies linking raw milk legalization to increased illness measured raw outbreak counts without controlling for consumption. More recent research, adjusted for consumption volume, shows outbreak rates declining as legal access has expanded.

Raw milk foodborne illness is measured two ways in the epidemiological literature: per serving consumed and per consumer. Both metrics produce low absolute rates.

Mammary glands produce no lactase. Here’s where the myth comes from, what actually does appear in bottled raw milk (and why), and what the science says about the widespread reports of people who say raw milk solved their dairy intolerance.

Multiple large European studies have linked raw milk consumption in childhood to lower rates of asthma and allergies. This article reviews what the research found.

Updated per-consumer raw milk illness data using Lando et al. 2022 (FDA) and Koski et al. 2022 (CDC). The consumer base is larger than prior estimates, putting the per-consumer illness rate at approximately 1 in 15,000 per year.

The “840 times more illness” statistic measures outbreak-reported illness per billion servings across four pathogens and not the per-consumer risk most people are asking about.

Harvard’s long-term cohort studies found a persistent link between ice cream consumption and lower diabetes and CVD risk. Here’s what the data actually shows.

Practical comparison of Charm Sciences peel plates and Neogen Petrifilm for on-farm raw milk testing with full materials lists, supplier links, and cost breakdowns from working dairies.
