Sharing is caring!

When following a keto diet, it’s important to carefully choose your foods to ensure they fit within the diet’s guidelines. Tomato soup, a popular comfort food, is often questioned whether it can be consumed on a keto diet.

In this article, we will explore the pros and cons of tomato soup on keto, provide some tips on making it keto-friendly, and offer delicious alternatives for those who prefer to avoid it.

The Pros and Cons of Tomato Soup on Keto

Tomatoes are generally considered low in carbs and high in fiber, antioxidants, and vitamins. These nutrients are beneficial for overall health and well-being. Tomato soup can provide hydration and electrolytes, which are especially important while following a keto diet that can be dehydrating. Additionally, tomato soup can add flavor and variety to the diet and be paired with keto-friendly foods such as cheese, bacon, or avocado.

However, there are some potential drawbacks to consider regarding tomato soup on keto. Depending on the ingredients and serving size, tomato soup can be high in carbs. Some canned or processed tomato soups may have added sugars, starches, or flours that are not keto-friendly. Furthermore, tomato soup can trigger cravings or inflammation in some people.

Tips for Choosing or Making Keto-Friendly Tomato Soup

To enjoy tomato soup on a keto diet, it’s important to choose or make it carefully. Reading the nutrition labels and ingredients list is crucial to selecting a low-carb option. Canned or processed tomato soups often have added sugars or fillers, so it’s best to avoid them. Making your tomato soup from scratch gives you complete control over the ingredients.

To make keto-friendly tomato soup, start with fresh or canned tomatoes, broth, cream, butter, herbs, and spices. Use a blender or immersion blender to puree the soup to a smooth consistency. Adjust the seasoning and thickness to your liking. It’s important to limit your portion size to 1/2 cup or less to ensure it fits within your daily carb limits.
