Breeders are also seeing poor fertility in male dogs. Many dog breeders suspect that phytoestrogen may be the reason their females are going into heat more than two times a year. Soybean products are high in phytoestrogen followed by legumes (peas and beans), whole grain cereals and oil seeds like flax. Phytoestrogen is a plant hormone that is similar (at a molecular level) to estrogen and is found in many plants. In the US, the push to consume whole grains high in antinutrients may be contributing to our magnesium deficiency along with our pets. Most Americans are deficient in magnesium and should be taking magnesium supplements daily. Deficiencies in magnesium are a contributing factor in heart disease. The most common minerals affected are calcium, iron, zinc, copper and magnesium. Phytic acid has a very strong ability to bind minerals in the digestive tract making them unavailable to your pet. Lipase inhibitors interfere with the production of fat enzymes produced by the pancreas and veterinarians are seeing more pets with pancreatic issues in recent years. These deficiencies can also lead to DCM heart disease in both dogs and cats. Enzyme inhibitors found in legumes like peas and beans can interfere with digestion and may be responsible for taurine and other amino acid deficiencies in our pets. Examples of these types of proteins would be Lections, trypsin inhibitors and enzyme inhibitors. Taurine is an essential amino acid that your pet needs to remain healthy.Ĭertain types of proteins can prevent the absorption of other proteins and be classified as antinutrient. Protease inhibitors can prevent the absorption of proteins and amino acids and may be responsible for the sudden epidemic of taurine deficiencies in dogs which can lead to dilated cardiomyopathy heart disease (DCM).Veterinarian’s are theorizing that the legumes and sweet potatoes used to replace grains in many dog foods may be binding the taurine in your dog’s food, causing DCM. Generally, proteins and fats derived from animal sources do not contain antinutritional properties and are a good choice for our cats and dogs. Fruit fibers, like tomato pomace, may be a better choice for a dietary source of fiber over pea or rice hulls. Fibers such as oat hulls, rice hulls and pea fiber tend to contain large amounts of antinutrients and should be avoided as a fiber source for your pets. Food starches are basically a pure form of highly digestible carbohydrates needed by all omnivores. Brown rice does contain more magnesium, but it also contains more of the antinutrient that binds all that magnesium from absorbing into our bodies.įew antinutrients are found in potato or corn-based food starches since the outer skin/hull, protein, fat and minerals have been removed. We’ve been told that brown rice is better for us than white rice because brown rice contains more magnesium. The vast majority of antinutrients are found in the outer hull of the seed: the skin of the potato or the brown skin found on rice. Antinutrients are vast and numerous, but they all have one thing in common they interfere with the absorption of nutrients necessary to keep your pet healthy. What exactly are antinutrients and why should I be concerned?Īntinutrients are natural compounds produced by plants to protect their seeds from animal consumption. The main difference between a grain-based food and a legume-based food is grains, specifically corn, are relatively low in antinutrients while legumes are relatively high in antinutrients. Two foods with the same level of protein and fat, one made with grain and the other made with legumes, will both have the same level of carbohydrates. But, being grain free does not necessarily mean less carbohydrates. Legumes include peas, beans, lentils, soybeans and peanuts. In order to make these grain-free foods, companies typically replaced grains with legumes. We assumed that grain free meant the food was lower in carbohydrates and therefore healthier for our pets. We have been told for years that we should be feeding our pets grain-free foods.
