The mineral selenium is high in Brazil nuts and supports the thyroid and the recycling of glutathione for optimal liver detox and breakdown of hydrogen peroxide in the body.

Tips and Substitutions
- I used my Vitamix blender to blend the soup as I found it easiest to blend the Brazil nuts into a super smooth and creamy texture. You can also use an immersion blender to blend the soup in the pot for minimal mess and no extra cleanup of the blender. Move the immersion blender around while blending to ensure the whole soup becomes creamy.
- Spice the soup with extra red pepper chili flakes for extra heat. I love the subtle yet spicy flavors of this creamy vegetarian soup with cauliflower.
- For an extra flavor kick try spicing the soup with dried rosemary and thyme. Fresh chives would also be a great addition.
- I prefer to avoid the saturated fats in cheese, but freshly grated parmesan or cheddar cheese would definitely taste so yummy!
- Store the soup in an airtight container, such as a mason jar, in the fridge, where it will keep for three days. If you won’t eat it all up in a few days, freeze any extras and defrost before reheating and serving.
While cauliflower is a fantastic high protein liver cleansing vegetable, if you have to many hydrogen sulfide gas producing bacteria, you may notice stinky gas when consuming high sulfur containing compounds found in cauliflower. The Viome gut test is an excellent gut test to find out if your microbiome is producing too much hydrogen sulfide gas, in which you may need to reduce the amount of sulfur containing vegetables and foods even though they are “healthy”.
I hope you enjoy this creamy, high-protein and easy cauliflower and white bean soup! It is perfect for weight loss as it is low in calories yet high in protein and many vitamins and minerals to support liver detoxification and overall health!
