Heart disease and grain free diets takeaways:
Common myths - more natural, carb free, less health problems such as allergies.
Myth: whole grains are filets with no nutritional value.
Whole grains are important sources of vitamins, minerals, and essential fatty acids.
Some grains do provide protein as well and it may actually be easier to digest for some animals.
Greater than 90% of dogs and cats *can* utilize nutrients from grains.
Myth: grain free is carb free
First, carbs are an important energy source and one of the 6 basic nutrients (water, protein, carbs, fats, minerals, vitamins)
Sweet potato has more carbs than corn
Grain free diets that *are* lower in carbs are in turn higher in protein and fat, which is not necessarily actually healthy for an animal.
The diets vary in levels of protein, fats and other nutrients.
Potato and cassava have fewer nutrients and less fiber than whole grains.
Beans, peas and lentils can cause GI upset.
MYTH: grains cause food allergies.
Actual food allergies are uncommon. Environmental allergies make up the majority.
Less than 1% of skin diseases and less than 10% of all allergy cases are actually food related. And grain allergies are one of the least common allergies of those.
For allergen causes tend to reflect the most common ingredients and change as those change. But no matter what, the most common food allergen is a meat source. NOT GRAINS.
Myth: grain causes gluten intolerance!
True gluten intolerance has so far only been found in one highly inbred lineage of Irish setters and that line no longer exists. It manifested as GI signs, not itching.
Gluten intolerance has never been found in a cat.
There is no credible evidence that grain free is better for pets, to date. There is no nutritional foundation for the claim.
The correlation (not causation, correlation) between grain free and heart disease in atypical breeds is currently being investigated.
Taurine deficiency? DCM used to be extremely common in cats until they figured out the link in 1980.
In 1990 both Golden retrievers and cocker spaniels were found to also get taurine deficiency related DCM.
Research takes a while. It might be done time before we have answers.
Grains are not the devil.
Boutique foods typically don't even have a veterinary nutritionist on staff.
None do lifetime feeding trials.
Different foods can interact in weird ways once inside an animal, impacting the body's ability to absorb or utilize nutrients.
Dogs do not need blueberries. Those are a marketing gimmick. Don't fall for it.
Don't spend money on tests claiming to identify foods allergies in your dog. They can't even tell the difference between animal hair and fake hair. They are useless.
Also, random meat sources often end up in boutique raw food diets that aren't declared on the label so you don't know what is actually in there.
