NOVA Classification System and Pet Food Companies

The NOVA classification system, created by Brazilian researchers, categorizes foods based on their processing levels. It’s a valuable tool for making informed dietary choices, distinguishing between processed and ultra-processed foods, and is widely used in nutrition studies and guidelines. The system divides foods into four categories, each representing a different level of processing.

Understanding Processed vs. Ultra-Processed Foods

The primary distinction between processed and ultra-processed foods lies in the degree of processing and the presence of artificial ingredients. While processed foods undergo minimal alterations and retain their nutritional properties, ultra-processed foods are heavily modified and often contain additives that can negatively affect health.

Unprocessed or Minimally Processed Foods

  • Characteristics: These foods are closest to their natural state and are rich in nutrients. They undergo minimal processing, retaining their original nutritional value.
  • Examples: Fresh fruits, vegetables, eggs, fresh meat.

Benefits:

  • Health Benefits: Consuming unprocessed or minimally processed foods is associated with numerous health benefits, including reduced risk of chronic diseases, better weight management, and improved overall health.
  • Environmental Impact: These foods often have a lower environmental footprint compared to processed foods, as they require less energy and resources for production and packaging.

Pet Food Companies:

  • Raw and Freeze-Dried Raw Foods:
    • Big Country Raw: Offers a variety of raw food options for pets, emphasizing ethical sourcing and nutritional balance.
    • HoliRaw: Renowned for their commitment to natural and nutritious raw meals, HoliRaw uses locally sourced, premium ingredients to ensure pets receive optimal nutrition with high safety and quality standards.

Processed Culinary Ingredients

  • Characteristics: These are substances extracted from foods or nature used to prepare and season foods. They are important for flavor but should be used in moderation to maintain a balanced diet.
  • Examples: Oils, butter, sugar, salt.
  • Companies:
    • Oils:
      • Cobram Estate: Cobram Estate prides itself on producing premium extra virgin olive oil. They are known for their commitment to quality, 
      • Nutiva: Specializes in organic coconut oil and other organic products.
    • Butter: Island Farms is known for its high-quality dairy products – they are well-regarded for their commitment to quality.
    • Sugar: Bob’s Red Mill is renowned for its high-quality, natural sweeteners, including organic cane sugar, brown sugar, and coconut sugar.
    • Salt: Vancouver Island Sea Salt is known for producing premium sea salt harvested from the pristine waters around Vancouver Island.

Note: While not directly linked to pet food companies, these ingredients play a role in home-prepared pet meals and treats.

Processed Foods

  • Characteristics:  Extended Shelf Life: Processed foods undergo various methods such as canning, drying, freezing, and the addition of preservatives.
  • Flavor Enhancement: Additional ingredients like salt, sugars, and oils are often incorporated to enhance the flavor, improve texture, and increase the overall appeal of the food. This makes processed foods more palatable and enjoyable for consumers.
  • Retention of Natural Properties: Despite the alterations, many processed foods retain most of their natural properties, including essential nutrients. 
  • These foods are altered to extend shelf life or enhance flavor while retaining most of their natural properties.
  • Examples: Canned vegetables, cheese, freshly baked bread.

Pet Food Companies:

  • Dehydrated Foods:
    • Open Farm
  • Fresh and Minimally Processed Foods:
    • Open Farm
  • Quality Processed Foods:
    • Fromm Family Foods: Offers dry and canned dog foods with premium proteins and whole grains, focusing on small-batch production for quality.
    • Open Farm: Committed to using ethically sourced and sustainable ingredients, offering dry, wet, and freeze-dried dog foods with a focus on transparency and superior nutrition.
    • Farmina: Known for its use of natural ingredients and nutritional science, offering both grain-inclusive and grain-free options. Farmina emphasizes balanced nutrition tailored to pets’ needs.

Ultra-Processed Foods

The NOVA classification system provides a detailed understanding of ultra-processed foods, which are characterized by their high levels of processing and the inclusion of various additives. Here’s some additional information about ultra-processed foods:

Characteristics:

  • High in Additives: Ultra-processed foods often contain artificial flavors, colors, preservatives, and emulsifiers to enhance taste, appearance, and shelf life.
  • Low Nutritional Value: These foods tend to be high in calories, sugars, unhealthy fats, and salt, while lacking essential nutrients like vitamins, minerals, and fiber.
  • Highly Palatable: The combination of additives and processing techniques makes these foods highly palatable, which can lead to overconsumption.

Examples:

  • Common ultra-processed foods include soft drinks, packaged snacks, instant noodles, and ready-to-eat meals.
  • In the context of pet foods, ultra-processed options often include conventional kibbles and wet foods with added flavors and preservatives.

Health Implications:

  • Regular consumption of ultra-processed foods has been linked to various health concerns, including obesity, heart disease, diabetes, and metabolic syndrome.
  • Cancer Risk in Humans:
    • Some research indicates that a diet high in ultra-processed foods is associated with a higher risk of developing cancers, particularly breast cancer and colorectal cancer.
    • The presence of additives, preservatives, and high levels of sugar and unhealthy fats in these foods may contribute to inflammation and other biological processes that increase cancer risk.
  • Cancer Risk in Pets:
    • While specific studies on pets are limited, the general understanding is that a diet high in ultra-processed foods could potentially contribute to cancer risk in pets as well. This is due to similar mechanisms involving additives and poor nutritional quality.
  • General Health Implications:
    • In addition to cancer, ultra-processed foods are linked to other health issues such as obesity, heart disease, diabetes, and metabolic syndrome, all of which can also contribute to an increased cancer risk.
    • Choosing minimally processed or whole foods, both for yourself and your pets, can help mitigate these risks and promote better health overall.

Advanced Glycation End Products (AGEs):

  • Formation of AGEs: Ultra-processed foods often undergo high-temperature processing methods, which can lead to the formation of AGEs. Ingredients commonly found in ultra-processed foods, such as high-fructose corn syrup, refined sugars, and certain fats, can contribute to the formation of AGEs.
  • Health Implications: High levels of AGEs in the diet have been linked to various health issues, including inflammation, oxidative stress, and an increased risk of chronic diseases like diabetes, cardiovascular disease, kidney disease, and cancer. For pets, diets high in AGEs might contribute to similar health concerns, affecting their overall well-being.
  • Reducing AGE Intake: Opting for fresh, minimally processed foods and using cooking methods like steaming or boiling can help reduce AGE intake. For pets, choosing foods with natural ingredients and minimal processing can also help lower their exposure to AGEs.

Pet Food Companies:

  • Kirkland Signature: Known for conventional kibbles with extensive processing and artificial additives.
  • President’s Choice: Offers ultra-processed kibble options similar to Kirkland.
  • Purina: Offers a wide range of conventional kibbles known for extensive processing and the inclusion of artificial additives.
