Is standardised milk healthier than other types of milk?

Quick answer

Not by itself. Standardised milk is regular pasteurized milk whose fat is adjusted to a fixed level so every carton is the same. That makes it consistent, not healthier. Which milk suits you depends on the fat level, any added vitamins and whether you tolerate lactose; check the label. In the US, milk must have at least 3.25 percent fat.

Is standardised milk healthier than other milk?

No official source says so. Standardised (US spelling: standardized) milk is simply milk whose fat and solids have been adjusted to a set level so that each batch matches, because raw milk varies with breed, feed and season. Many packaged milks are adjusted this way, so it is often not a special category. What matters for your health is the fat level and what is added, not the word standardised.

What does standardised mean on a carton?

  • The fat content has been set to a stated percentage.
  • It is normally pasteurized, meaning heat-treated to kill harmful germs.
  • It may be homogenized, so the cream does not rise to the top.

The rules differ by country. In the US, milk must contain at least 3.25 percent milkfat and 8.25 percent milk solids not fat, and vitamin A and D may be added. Other countries use their own named grades and percentages, so read your carton and local rules.

How does it compare with other types?

Choice What differs
Whole or full cream Highest fat, most calories
Reduced or low fat Less fat and fewer calories
Skim Almost no fat
Lactose-free Lactose broken down; NIDDK says it is as healthy as regular milk

How do you choose?

  • Look at the fat percentage and calories on the Nutrition Facts or nutrition table.
  • Check whether vitamins A and D are added.
  • Choose lactose-free if regular milk upsets your stomach.
  • Ask a doctor or dietitian if you have a health condition or are choosing milk for a young child.

Not necessarily. It is often the same product with a consistent fat level. Compare the fat percentage on the label.
