Sour Cream on a kitchen counter

Is Sour Cream Keto-Friendly? Well, the answer largely depends on moderation.

Sour Cream, with its creamy texture and tangy taste, can indeed find a place on your keto menu, but it's a spot that comes with a few caveats.

With a noteworthy amount of net carbs per serving, Sour Cream must be limited in a ketogenic diet to avoid tipping your daily carb count.

In this article, we will dive into the specifics of Sour Cream's carb content, explore how to enjoy it in moderation on a keto diet, and discuss its overall nutritional benefits.

So, if you're a keto dieter who loves a dollop of Sour Cream on your dishes, keep reading for a comprehensive breakdown of this dairy delight's place in your meal plan.


  • Sour Cream can be keto-friendly, but only in moderation due to its carb content.
  • Enjoying Sour Cream in your keto meal plan requires strict portion control and careful carb counting.
  • Overconsumption of Sour Cream could potentially disrupt ketosis and may lead to an increase in LDL cholesterol.

Is Sour Cream Keto-Friendly?

Sour Cream is indeed considered keto-friendly, but it's important to note the stipulation that it should be consumed in moderation. The reason behind this advice lies within its nutritional composition.

The carbohydrate content of Sour Cream stands at 5.56g per 100g serving. While this isn't a high amount by general nutritional standards, it can add up quickly for those following a strict keto diet which typically limits carb intake to about 20-50g per day. Thus, even though Sour Cream does fit into a ketogenic lifestyle, its consumption must be carefully controlled.

Can You Have Sour Cream on a Strict Keto Diet?

Incorporating Sour Cream into a strict Keto diet, which limits carb intake to less than 20g per day, requires careful portion control. Given that a 100g serving of Sour Cream contains 5.56g of net carbs, it can quickly utilize a significant portion of your daily carb allowance if not monitored closely.

Despite this, it's not impossible to include Sour Cream in a strict Keto diet. It simply means that the portion sizes must be kept small and adjusted according to the rest of your daily carb intake. For instance, a smaller 50g serving of Sour Cream would contain roughly 2.78g of net carbs, which fits more comfortably within the tight carb restrictions of a strict Keto diet.

Wider carb intake limits, such as those in a low-carb or moderate Keto diet that allows for 30-50g of net carbs per day, offer more flexibility for including Sour Cream. In these cases, the portion size can be slightly larger, but careful tracking of carb intake remains crucial.

Carbs In Sour Cream

Sour Cream contains 5.56g of net carbs per 100g serving. This value is crucial for those following a ketogenic diet, as net carbs are what's left when dietary fiber is subtracted from total carbohydrates.

Sour Cream Nutrition Facts

A 100g portion of sour cream is rich and varied in its nutritional content. Primarily, it contains 17.99g of total fats, significantly composed of 10.7g of saturated fatty acids and 3.8g of monounsaturated fatty acids. With a carbohydrate content of 5.56g, it also offers a moderate protein contribution, standing at 3.07g.

Being a dairy product, sour cream naturally carries essential micronutrients. Its standout minerals include calcium (107.2mg) for bone health, potassium (153.8mg) for maintaining fluid balance, and a modest amount of magnesium (10.11mg), which plays a role in many bodily functions.

There is presence of sodium (50.04mg), phosphorus (102.0mg), zinc (0.39mg), and iodine (32.75ug), each playing unique roles in supporting body functions. It also contains 52.69mg of cholesterol, which, while often stigmatized, is actually vital for creating hormones and Vitamin D.

In terms of vitamins, sour cream is not left behind. It provides Vitamin B-6 (0.04mg), Vitamin B-12 (0.06ug), thiamin (0.04mg), niacin (0.1mg), and biotin (1.91ug), all vital for energy production and cell health. The inclusion of retinol (151.5ug) also aids in supporting vision and immune function.

Health Implications of Sour Cream on a Keto Diet

On a Keto diet, maintaining a state of ketosis is paramount, and Sour Cream, while keto-friendly in moderation, can present challenges if not consumed carefully. The key lies in its carb content, with 5.56g of net carbs per 100g serving. If not monitored closely, these carbs can add up and potentially push one over their daily carb limit, thereby disrupting ketosis.

Aside from its carb content, Sour Cream has other nutritional aspects to consider. It is a good source of several nutrients like calcium and vitamin B12. Calcium is crucial for bone health, while vitamin B12 plays a key role in nerve function.

However, it's also high in saturated fats. While fats are a crucial part of the keto diet, it's important to balance the types of fats consumed. Saturated fats, if consumed excessively, can lead to health issues such as an increase in LDL (bad) cholesterol.

Finally, Sour Cream contains lactose, a type of sugar found in dairy products. Some individuals have lactose intolerance, which means their body can't easily digest lactose. For these individuals, consuming Sour Cream could lead to digestive issues.

Incorporating Sour Cream Into Your Keto Meal Plan

  1. Pair it with Keto-Friendly Foods: Sour Cream can be a delightful addition to many dishes. Try adding a dollop to a bowl of low-carb chili or a serving of scrambled eggs. It can also be used as a base for a rich, creamy keto-friendly dip for vegetables.
  2. Portion Control: Before adding Sour Cream to your meal, measure out your serving size to ensure you stay within your carb limit. A food scale can be a useful tool for this.
  3. Creative Keto Recipes: Sour Cream can be used in a variety of keto recipes. For instance, it can be used to make a creamy dressing for salads, mixed with herbs and spices to make a flavorful sauce for grilled meats, or used in low-carb baking for moisture and richness.

Keto-Compatible Alternatives for Sour Cream

  1. Greek Yogurt: Plain, unsweetened Greek yogurt can be a great keto-friendly alternative to Sour Cream. It offers a similar creamy texture and tangy taste, with fewer carbs and a higher protein content.
  2. Cream Cheese: Another low-carb option is cream cheese. While the texture is a bit thicker, it can provide a similar rich taste to Sour Cream in many dishes.
  3. Avocado: For a dairy-free alternative, mashed avocado can add creaminess to your dishes. Plus, it's high in healthy fats, which are beneficial on a keto diet.

Concluding Thoughts on Sour Cream and Keto

Sour Cream's place in a Keto diet is one of careful balance. While this creamy dairy product can be enjoyed in moderation due to its carb content of 5.56g per 100g serving, its inclusion in your meal plan requires strict portion control and diligent carb counting to ensure you stay within your daily carb limit and maintain ketosis.

Furthermore, the nutritional profile of Sour Cream - from its high saturated fat content to its lactose content - means it should be considered as part of a wider balanced diet, with variety being key to nutritional wellness.

Reducing Sour Cream in your Keto diet could involve seeking out alternatives, such as Greek yogurt, cream cheese, or even non-dairy options like mashed avocado and unsweetened coconut cream. This allows you to replicate the creaminess of Sour Cream without the same carb content.

Cast Iron Keto's Editorial and Research Standards

Certain rare or exotic food items may not have nutritional profiles in the FoodData Central database. If an exact match is not found in the FoodData Central database, then, the Cast Iron Keto team utilizes a three-prong approach to provide readers with the closest relevant nutritional data, where possible.

First, in the event that nutritional profiles for a rare or exotic food item is not available in the FoodData Central database, we investigate alternative names for that particular food item and use that data, when possible. Second, in cases where no alternate names exist, Cast Iron Keto will use nutritional data for a close relative or similar food item. Finally, if no close relatives or similar items exist, we refrain from publishing nutrient data tables.

When making dietary or health decisions based on FoodData Central's data, we suggest readers consult with a nutritionist or other health experts, particularly if the food in question has a significant role in your diet or if you are using the food item to treat any health disorder(s).

Furthermore, it is important to note that even if a close relative or similar item is used to approximate the nutritional data, different food items can have varying levels of nutrients due to factors such as soil quality, farming practices, and regional differences.
