Is Diced tomatoes Keto?
Yes, diced tomatoes are generally considered keto-friendly. While they do contain natural sugars, their net carb count is low enough to fit within the strict limits of a ketogenic diet. This article breaks down the specific ingredients and nutritional values to ensure you can enjoy them without breaking your ketosis.
The Ingredient Breakdown
When evaluating a product for the ketogenic diet, the ingredient list is just as important as the nutrition label. Fortunately, standard canned diced tomatoes are remarkably clean. Let's look at the specific components found in a typical can.
The primary ingredient is, of course, diced tomatoes. Tomatoes are a fruit, but they are low in sugar compared to others, making them a staple in many keto pantries. They provide essential vitamins without spiking insulin levels significantly. Following this, you will usually find tomato juice. This is simply the natural juice from the tomatoes themselves, used to maintain freshness and texture. It adds a negligible amount of carbs compared to the volume of the can.
For preservation, manufacturers use sea salt, which is perfectly acceptable on keto as it helps maintain electrolyte balance. The other two ingredients, calcium chloride and citric acid, are standard food additives. Calcium chloride is a firming agent used to prevent the tomatoes from turning into mush during the canning process. Citric acid acts as a preservative and flavor balancer. Neither of these adds carbohydrates, calories, or fats, making them inert regarding your keto macros.
Nutritional Value
Understanding the nutritional profile of diced tomatoes is key to fitting them into your daily macros. A standard serving size, typically half a cup, contains approximately 4 to 5 grams of total carbohydrates. However, the ketogenic diet focuses on net carbs (Total Carbs minus Fiber).
Because tomatoes are a good source of dietary fiber, the net carb count for a serving of diced tomatoes drops to roughly 2 to 3 grams. This is a very manageable number, even for those following a strict 20-gram daily limit. Furthermore, diced tomatoes are extremely low in calories and contain virtually no fat, making them a high-volume, low-calorie food that helps you feel full.
Regarding sugar, while tomatoes contain natural fructose, the amount in a serving of diced tomatoes is minimal compared to other canned vegetables or fruits. As long as you account for these few grams of carbs in your daily tracking, diced tomatoes pose no threat to your state of ketosis and are a healthy addition to the diet.
