Sour Cream Benefits
Not only does sour cream taste great, but it also has some nutritional benefits.
Sources of Fermented Dairy May Have Benefits
One reason for this appears to be the abundance of bacterial species contained within fermented dairy, such as various Lactobacillus and Streptococcus strains (3).
On this note, several studies have found that fermented dairy intake may have beneficial health effects.
For example, a dose-response meta-analysis of over 29 studies demonstrated an inverse relationship between fermented dairy and cardiovascular disease (4).
Furthermore, a wide variety of research suggests that fermented dairy has a beneficial effect upon gastrointestinal health and—possibly by extension—systematic health. These benefits are likely due to the probiotic bacteria that they contain (5, 6).
Compared to regular cream, the probiotic content of sour cream may offer some additional benefits.
Rich in Important Nutrients
As we saw from the nutritional values, sour cream contains a broad range of nutrients.
Sour cream is particularly high in vitamin A in its most bioavailable (retinol) form, riboflavin (vitamin B2), calcium, and phosphorus.
After calcium, phosphorus is the most abundant mineral in the body, and approximately 85% is stored in the bones (7).
It plays a vital role in strengthening our bones and maintaining dental health (8).
Half a cup of sour cream contains approximately 7% of the daily value for phosphorus (1).
Vitamin A is essential for our eyesight, immune system, and optimal bone growth.
In particular, it plays a major role in protecting against macular degeneration (9).
The vitamin is also present in carotenoid-rich vegetables such as carrots and sweet potatoes.
However, animal foods such as sour cream supply vitamin A in its pre-formed state. This is important because vegetables contain provitamin A carotenoids, which require conversion to true vitamin A (retinol) before they can be used by the body.
On this note, retinol is thought to be approximately twelve times more bioavailable than beta-carotene (10).
A half-cup of sour cream contains around 16% of the daily value for vitamin A (1).
Riboflavin plays a host of roles in the body.
Most significantly, it produces energy through the metabolism of carbohydrates, fats, and proteins (11).
Riboflavin may also have antioxidant properties and help to fight free radical damage in the body (12).
A half-cup serve of sour cream supplies approximately 15% of the daily value.
Improves the Nutritional Value of Salad
Leafy greens used in salads contain a significant amount of fat-soluble vitamins such as vitamin A and vitamin K.
Sour cream often features as a salad dressing, which can be beneficial due to its fat content.
Additionally, using a dressing makes salad taste a lot better too.
For a quick and easy sour cream-based salad dressing, the following recipe works well:
- 1 cup sour cream
- Juice of half a lemon
- 4 cloves of crushed garlic
- 1 tbsp red wine vinegar
- 1 tbsp tamari soy sauce
- Sprinkle of pepper
For a healthy and tasty salad dressing, just blend/mix these ingredients.
Makes a Great Dipping Sauce
Sour cream can also provide a great base for a dipping sauce.
Making a dip is simple, and the only ingredients you need are some garlic, salt, and onion.
Add them to the sour cream, add an egg yolk or two, and blend for a thick and creamy dipping sauce.
A Good Source of Calcium
Similar to all dairy products, sour cream provides a significant amount of calcium.
Calcium deficiency is common in the modern world, especially among certain groups.
For instance, studies show that less than 10% of females in the 14-18 and 51+ groups have an adequate calcium intake (15).
Additionally, the mineral also appears to play a role in maintaining an optimal blood pressure (18).
Sour cream is a delicious high-fat dairy food that also offers several nutritional benefits.
Not only is it nutritious, but it also works well in a wide number of tasty recipes.
