Prostokvasha (clotted sour milk): Nutritional Values & Calorie Data

Nutritional Overview

Prostokvasha (clotted sour milk) is a dairy or egg-based product that forms a staple part of many diets. Per 100g serving, it provides 55 kcal of energy, 3.0g of protein, 4.5g of carbohydrates, and 2.5g of fat.

It is a good source of protein, providing 3.0g per 100g (around 22% of its energy), approximately 6% of the UK Reference Nutrient Intake of 50g per day. Under UK/EU nutrition-claim rules, that meets the "high protein" threshold of at least 20% of energy from protein. Protein plays a key role in muscle repair, immune function, and keeping you feeling full for longer.

With just 2.5g of fat per 100g, it meets the UK/EU "low fat" nutrition-claim threshold. This makes it a lighter option for those monitoring their fat intake as part of a heart-healthy or weight-management diet.

With only 4.5g of sugar per 100g, it meets the UK/EU "low sugar" nutrition-claim threshold. This makes it a suitable choice for those reducing their sugar intake as part of a balanced diet.

With 115mg of calcium per 100g, it contributes meaningfully to daily calcium needs (the UK recommendation is 700mg for adults). Calcium is vital for maintaining strong bones and teeth, as well as supporting normal muscle and nerve function.

Each 100g serving contains 0.10g of salt, meeting the UK/EU "low salt" nutrition-claim threshold. The NHS recommends adults consume no more than 6g of salt per day, so choosing lower-salt foods like this one makes it easier to stay within that limit and supports healthy blood pressure.

Prostokvasha (clotted sour milk) is suitable for vegetarian, halal and kosher diets, making it a versatile choice for households with mixed dietary requirements.
