Before answering the question, please, allow me to talk a little bit about this type of nut, originated in South America.
Did you know that peanuts are technically not nuts? They actually belong to the legume family, therefore, related to beans, lentils, and soy.
Yes, you read it well: legume family.
Okay, what is a legume then?
A legume is a simple, dry fruit contained within a shed or a pod. The most well-known legumes are peas, beans, peanuts, and alfalfa.
Legumes are high in protein, excellent sources of minerals and fiber.
Great, huh!? So, how can these vegetal proteins, minerals and fiber help my K9 carnivore friend?
In fact, they cannot help that much. In the book Raw and Natural Nutrition for Dogs, PhD Dr Lew Olson says “plant protein do not meet your dog’s nutritional needs”. As carnivores, the best protein source for our dogs is meat of any kind. That said, plant protein does not satisfy our dogs nutritionally and, even worse, they can create a host of other problems as well. Poor quality protein, according to Dr Olson, are taxing on our dogs’ liver and kidneys and over time can cause deficiencies that may compromise even the healthiest dog’s organs.
The peanut butter matter
Sorry, but I must say, it’s not safe for your dog even if it’s just ‘a treat’.
We all know that treats are part of the diet. The closest to the Nature they are the better the diet.
I highly recommend you read the Dogs Naturally Magazine article that answered this question pointing a few things that are definitely not safe for our companion dogs and astonishingly bad for us. Following, a summary of the main reasons on why you should avoid peanut butter retrieved from the article written by Dana Scott.
#1. Most Peanut Butter Contains Aflatoxins (Which Cause Cancer)
Aflatoxins are naturally occurring mycotoxins produced by a fungus called Aspergillus. And peanuts have them in spades.
Mycotoxins are one of the most carcinogenic (cancer-causing) substances on the planet and they’ve also been shown to be toxic to the liver. Aflatoxin is known to cause liver cancer in laboratory animals … and it would probably do the same in your dog.
#2. Most Peanut Butter Often Contains Harmful Fats
Trans-fatty acids are one of the most toxic food substances today. Trans-fats are the result of a highly toxic process that makes foods more stable, allowing them to sit on shelves for an extremely long time. Hydrogenation is the process of taking a plant oil, adding a nickel catalyst, heating it, and then removing the nickel catalyst.
The result is a highly toxic fat that causes diabetes, heart disease and chronic inflammation.
#3. Most Peanut Butter Contains Sugar
Think of white sugar as food for all of the nasty things we take our dogs to the vet for… like yeast (candida), bacteria, parasites – and cancer! The more we eat, the more they feast!
Sugar can also cause diabetes, food allergies, premature aging and low-level inflammation. And it feeds cancer cells.
Speaking of inflammation, that’s one more reason why peanut butter isn’t a great snack choice for your dog.
While peanuts are high in good monounsaturated fats, their omega 6 to 3 ratio is terrible! One cup of peanuts contains 35578 mg of omega-6 fatty acids and only 196 mg of omega-3 fats. Omega-6 polyunsaturated fatty acids (PUFAs) can trigger inflammation, so too much is not good. The most common inflammatory conditions in dogs include allergies and joint disease.
It’s always good to remember that, if it is packed, it is not ‘natural’ at all. If you aren’t planting, sorry (again), it’s not 100% natural.
For dog’s sake! That’s the propaganda! I know that from experience, after working in the field for more than 15 years!
Advertisement guys are really good. After all, companies pay millions to advertise their products. But it’s our choice to be well informed to make the best decision for our companion pets.
If you used peanut butter before or are still offering for your dog, please, don’t make this a killer tool, just think about it and give yourself a chance to change this habit. Temperance is one of the laws of health, so, take your time, read about it, empower yourself and get ready to make positive changes for you and your pets.
Kong Stuffing Healthy Idea
As a Carnivore Nutrition Coach, I’ll always be in favor of meat.
For me the best option for Kong toys is minced muscle or organ meat.
When meat content is frozen, microorganisms are dormant and don’t cause any damage to your dog, who pH level in the stomach is 1-2. This low pH level is ideal for quickly breaking down protein and neutralizing harmful bacteria. There is no need to worry!
