What are anti-nutrients?

Anti-nutrients are natural or synthetic compounds that interfere with the absorption of nutrients.

Anti-nutrients from grain-replacements (like peas and soy) in grain-free dog foods may intefere with the absorption of essential nutrients

Anti-Nutrients like Peas and Lentils May Be Hurting Dogs

In dog food, some leading scientists fear that anti-nutrients contained in newly common dog food ingredients may be blocking the absorption of essential nutrients (such as taurine), causing disease and even death. Legumes have been the most implicated source of anti-nutrients, which include peas, chickpeas, lentils, beans, tapioca, and soy.

Grain Replacements are Packed with Anti-Nutrients

The grain-free dog foods that were alleged to be causing a potentially fatal heart condition known as DCM (dilated cardiomyopathy) nearly all contained legumes or potatoes. Although only a correlation and no causation has been proven, the increase in the use of anti-nutrient-dense foods combined with the increase frequency of DCM is concerning.

We don't use any anti-nutrients

That's why Sundays never uses the anti-nutrient packed ingredients that are implicated in this ongoing issue. We do NOT use: potatoes, peas, lentils, chickpeas, rice, soy or gluten. These cheap starches are necessary to make kibble, but they are not needed in our air-drying process.
