About sour cream

Cream fermented with lactic acid bacteria until it thickens and sharpens. Crème fraîche is the same idea with a higher fat cream and a milder culture; both are cream first and a ferment second.

Also known as Cultured cream, Smetana, Crème fraîche (related)

The evidence in depth

Best supported: Insufficient

What each association actually rests on, and the papers behind it. A rating describes the state of the research, not how impressive the food is. How we rate evidence.

Evidence is limited for sour cream and gut bacteria. It is cultured, but the strains are chosen for flavour and texture rather than for survival through the gut, and no human study has tested it.

Insufficient evidence. Not enough human research to say anything useful yet.

Nutrient values are per 100 g of the USDA reference entry named on this page and vary with variety, growing conditions, storage and preparation.

Source record: Cream, sour, cultured (USDA FoodData Central, FDC ID 171257).

% DV uses the FDA Daily Values for adults and children aged 4 and over. A dash means no Daily Value has been established for that nutrient.

Bioactive compounds

Compounds present in meaningful amounts. Presence is banded rather than quantified, because whole-food levels vary enormously with variety, growing conditions, storage and preparation.

How preparation changes things

Only effects with real support are listed. If a preparation method is missing, it is because nothing dependable is documented — not because it makes no difference.

  • fermentedReduces lactose

    Lactic acid bacteria convert part of the lactose to lactic acid during culturing, which is also what thickens the cream.

Things to know

Allergies, interactions and intake concerns. Every food gets this section — a reference where everything is uniformly good is not a reference.

  • Too much

    Concentrated dairy fat

    Sour cream is cultured cream, so it is dominated by saturated dairy fat and supplies little protein. Reduced-fat versions usually replace the fat with starch and gums.

  • Allergy

    Cow milk protein allergy

    A major regulated allergen.

  • Worth knowing

    Lactose partly consumed

    Culturing removes some of the lactose but not all of it, and cream contains less to begin with than milk. Tolerance is usually better than with milk, at the portion sizes sour cream is normally eaten in.
