What's 𝑹𝒆𝒂𝒍𝒍𝒚 In The Bag: Purina ProPlan Sport Ingredient #3 Brewer's Rice
Updated: May 12
Welcome back to the 3rd ingredient of this series. The drive of this deep-dive series is to be able to empower you with the information you need the be the best possible health advocate for your dog.
Now, let's get into the #3 ingredient... Brewer's Rice.
What's Brewer's Rice?
Brewer's Rice is exclusively sold to the pet food industry. It is a cheap and low-quality filler added to boost protein content and bind the kibble together.
Brewer's Rice is made out of small milled fragments (5/164 of an inch) of rice kernels that have been separated from the larger kernels of milled rice. “Dust” and “floor sweepings” from rice.
Brewer's rice isn't even whole rice. It's small scraps that are leftover from white rice that is processed for human consumption.
High Glycemic Load
Since brewer's rice is a by-product of white rice, it has a very high glycemic load.
This is a recipe for disaster!
Kibbles are loaded with carbs, starches, and sugars that are high on the glycemic index scale because they need these substances to bind the food together as well as boost protein-content without the use of animal sources.
glycemic index: 0 to 100 assigned to food, with pure glucose arbitrarily given the value of 100, which represents the relative rise in the blood glucose level two hours after consuming that food
Using sugars as a primary source of fuel (glycolosis) feeds metabolic diseases such as cancer, diabetes, and obesity. With over 50% of the modern canine population being obese, more high glycemic carbs are not what we need in pet foods.
Carbohydrates are a long chain of glucose. When a starchy carb is consumed it is broken down into glucose which the body uses for fuel. When the body uses glucose, insulin is released to move the blood sugars (glucose) into the cells to use as energy.
Insulin is found in canines and humans. It is the only hormone that lowers blood pressure (BP) while 8 raises it.
Dog's bodies (and ours) are equipped to raise BP when glucose is scared rather than lower it when there is an abundance. This is because, canines are not programmed to hunt for starches as a fuel source, they're meant to use fat!
Why are carbohydrates added if dogs don't need them? Same reason kibble manufacturers add-in ingredients like Corn Gluten Meal, it's cheap to add in and it boosts protein content. Since Chicken, the assumed #1 ingredient, is not making up the majority of the protein, manufacturers rely on plant protein such as corn gluten meal and brewer's rice to make up the protein content.
This becomes a problem for the consumer when choosing which bag to purchase. Since AAFCO does not require a min/max on carbohydrates in the guaranteed analysis (GA), it leaves a gap for the owner to fill. So words such as "protein-filled" and "carnivore" lead pet owners to be persuaded by the packaging.
Let's look at biology! What is our dog's physical and biological build telling us they need?
Let's take a look...
Dogs have canines to tear, rip, and crunch raw meat and bones. They do not have molars, like a horse, that is meant to grind vegetation...
Dogs are physically and biologically carnivores. They are equipped with canines to rip, tear, and crush through raw flesh and bone. Not only is their mouth made for raw meat, but their digestive tract is as well. With a highly acid stomach pH of 1, healthy dogs are built to digest raw meat withstand any pathogenic bacteria present.
Dogs do not have molars, like horses, to grind vegetation constantly. Horses have a stomach pH of 6, which is alkaline. We would not feed a horse a meat-based diet, therefore we should not feed dogs such a heavy load of carbs, sugars, & starches.
Canines DO benefit from a small amount of quality & low glycemic vegetation. They provide antioxidants, polyphenols, phytonutrient, vitamins/minerals, and more
Brewer's Rice is:
So why are Purina worth $10.3 billion dollars while supposedly keeping our dogs "happy and healthy with Purina Pro Plan"...because they have infiltrated not only the market but vet offices as well!
