Q: pasteurized milk vs cow milk?
A: Cow milk refers to the raw dairy straight from the udder, whereas pasteurized milk is that same milk gently heated to kill harmful pathogens. While raw milk preserves natural enzymes, it carries high foodborne illness risks; pasteurization ensures safety and longer shelf life while retaining identical nutritional value.
Key Differences
- Safety: Raw milk can contain harmful bacteria like E. coli, Salmonella, and Listeria. Pasteurization eliminates these disease-causing germs, making it much safer for children, the elderly, and those with compromised immune systems.
- Nutrition: Both milks offer nearly the same amounts of protein, calcium, and fats. However, raw milk advocates point out that heat-sensitive nutrients and beneficial enzymes are lost during pasteurization. Major health agencies maintain that the nutritional differences are minimal.
- Shelf Life: Raw milk spoils quickly (usually within a few days). Pasteurized milk stays fresh much longer, typically lasting 1–3 weeks when properly refrigerated.
- Digestion: Neither form cures or prevents lactose intolerance.
Which Should You Choose?
In India, "raw" milk from local suppliers often undergoes boiling at home, which acts as a form of pasteurization. If you are sourcing milk locally, be sure to boil it to destroy potential contaminants. For immediate, ready-to-consume convenience and reliable hygiene, commercially packaged pasteurized milk (like those from Nandini, Heritage, or Aavin) is the standard and safest choice.
