% Daily Value is how much 100 g contributes to the FDA Daily Values for adults and children 4 years and older, the figures on US nutrition labels; a dash means there is no Daily Value for that nutrient. "Not reported" means USDA has no measurement for this food, not that it contains none.
How Kefir fits common diet targets
- Net carbs
- 7.5g
- per 100 g
- Protein per 100 kcal
- 6.9g

- very low
- Net carbs are total carbohydrate minus fiber: 7.5 g − 0 g = 7.5 g per 100 g. Low-carb plans usually count these.
- Protein per 100 kcal compares how much protein each food gives for the same calories: Kefir gives 6.9 g.
- Energy density is calories per gram. At 0.52 kcal/g, Kefir is very low on the CDC's scale (very low below 0.6, low to 1.5, medium to 4, high above 4); lower-density foods give a larger portion for the same calories.
