Nutrients matter, not ingredients

Eric Weisman, CAHP, CEO, Nutrient Compound Scientist of Evolution Diet, (former human physician) & Darwin Brightsman, PhD, Animal Nutritionist invented, formulated and pioneered the world's 1st plant protein - plant oil vegan cat - dog foods starting over 30 years ago.  At that time, pet food studies conducted by the Nutrition Research Council (NRC) and other nutrition scientists proved the same proteins, fatty acids (oils), vitamins and minerals found in animal tissue could be easily found in plants and then used as meat alternatives in pet foods and have the exact same nutritional benefits for cats and dogs. 

In a recent review of plant-protein, plant oil pet nutrition research, Sarah Dodd noted that in accordance with current studies of cat-dog nutrition, the importance of nutrients, not ingredients, is emphasized. A diet that supplies all the required proteins, fatty acids, vitamins and minerals in accordance with updated nutrient profile research established by the Nutrition Research Council (NRC) and American Association of Feed Control Officials (AAFCO) studies – plant- or meat- based – have been found to be more than sufficient for good healthy long life of cats and dogs.1

To reiterate, it is the nutrients in pet food that matter regardless of whether they come from plants or animals. Nutrients support the life functioning of bodily systems and because of established scientific studies, the same nutrients found in animal tissue can and are easily derived from plant sources, where they are present in abundance. A balanced combination of plant ingredients with supplemented nutrients creates healthy, nutritionally complete formulas for dogs and cats.  Evolution Gourmet Fondue Non GMO Oatmeal based, Maximum Life Non GMO and Ultra LIfe Organic Kibble Foods may be the world's only "100% Complete For All Life Stage Cat and Dog Foods formulated to meet both NRC and AAFCO Nutrient Profile Requirements.  

Plants are excellent sources of protein

According to the AAFCO, adult dogs require at least 20% protein content in their food, adult cats – 26%.2Kittens under 1 year of age require a higher 30% protein for growth and development.2 Protein requirement is easily fulfilled by addition of high-protein plants as main ingredients in dog and cat foods - soybean meal, corn gluten meal, etc). 

Plant protein sources in pet nutrition is a hot research topic, and many studies demonstrated validity and excellent value of plant ingredients for dog and cat nutrition.3 In fact, it was found that amino-acid profile of soy is comparable to that of meat, and almost all essential amino acids for dogs and cats can be obtained from a combination of soy with other plant ingredients (with exception of taurine).

Peas and lentils are also great protein sources, with a balanced profile of digestible amino acids.2 Peas, in particular, provide most of the essential amino acids for dogs and cats, and are also an excellent source of carbohydrates and several essential vitamins and minerals.

Unlike animal protein, plant proteins are not common allergens and have not been associated with negative reactions in dogs and cats.According to  Armaiti May, a vegan veterinarian, allergy to meat protein is one of the most common food-related allergies in dogs, causing a host of skin issues. Transitioning to plant-based food alleviates the symptoms and improves quality of life of these animals. For these and other reasons, plant-based formulas are often considered hypoallergenic.


Other healthy ingredients in Evolution Diet products

Sunflower seeds – this ingredient has many benefits for health of cats and dogs. It contains vitamins B and E, which prevent and remedy skin conditions in companion animals. It also has an anti-inflammatory effect and is good for the cardiovascular system.

Grains - oats and corn are among the most commonly used grains in pet foods.  Sarah Dodd, a veterinarian, notes that while soy is probably the best ingredient from the amino-acid perspective, corn is a great source of several other essential nutrients, such as essential fatty acids, antioxidants (beta-carotene), vitamin E and lutein. Dogs and cats easily absorb essential nutrients from grains as shown by quite many research studies.4

ingredients rich in methionine

Yucca Schidigera root benefits functioning of the liver and the immune system, strengthening the whole organism. This root also improves functioning of the intestine, as well as significantly reduces the odor of excrement.

Cranberries protect the urinary tract system from bacteria and infections, and promote normal functioning of the kidneys and adrenals.

Tapioca provides non-toxic starch that binds ingredients in dry kibble – a natural, healthy binding agent.

Nutritional yeast – this type of yeast used in our kibbles was specifically formulated for companion animals. It’s more acidic than the regular store-bought yeast and is very beneficial for urinary health. It also contains B-complex water-soluble vitamins B1, B2, B3, B5, B6, B7, and B9 to support the nervous system, and is a natural source of chromium and high quality protein. Pets love its taste and become less prone to fleas with help of this amazing non-GMO, human-grade ingredient.

Vitamins and minerals

Both animal- and plant-based diets rely on supplementation of minerals to be nutritionally complete and balanced.1 Most vitamins and minerals required by cats and dogs are readily available in plant-based ingredients, and some are supplemented to provide complete nutrition.

Vitamin A requirement is achieved by addition of vegetables that contain precursor provitamin A carotenoids (in red, yellow, green and orange vegetables). Supplemented vitamin A analog is also added to plant-based diets.

Vitamin B complex includes a number of essential nutrients, such as thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin (vitamin B7), folate (vitamin B9), and cobalamin (vitamin B12). All vitamins in the B-group are readily available in plant sources, except cobalamin (vitamin B12). For this reason, all plant-based formulas are supplemented with vitamin B12.

Cats and dogs (unlike rats and other herbivores) do not convert UV rays to vitamin D and so all plant-based formulas are supplemented with vitamin D.

Vitamin E is also added to our formulas, which has many health benefits. This vitamin has the potential to protect cell membranes from damage and maintain their elasticity, inhibit oxidation and promote growth and regeneration. Vitamin E is the source of additional strength and energy for your animal.

All essential minerals for dogs and cats are also added to our formulas in correct proportions. A recent research study looked at how dogs digest supplemented minerals from meat-based and vegetable-based diets, and found that digestibility of essential minerals (such as iron, calcium and zinc) was equal to or greater in dogs fed vegetable-based diet. 5 In other words, dogs on plant-based diet easily digest and absorb all essential minerals.
