Whole Oats

Oats are grown for food and feed. Harvested grains arrive with a fibrous hull around each kernel. Milling cleans them and may remove the hull while keeping the bran, germ and starchy center.^1,2,7,8

1. 01 // Source Harvested oats Mature oat grains arrive at the mill enclosed in their outer hulls.
2. 02 // Process Cleaned Milling removes field debris before the grain is used for food or feed.
3. 03 // Process Hulls removed optionally Removing the fibrous hull leaves a groat that still contains the bran and germ.
4. 04 // Process Ground if needed Trials used ground groats or rolled oats before cooking them into complete dog diets.
5. 05 // Output Whole oat grain The cleaned grain or groat reaches the kibble plant as a source of starch and fiber.

1. 01

   Supplies digestible energy

   Starch makes up most of a dehulled groat. In dog feeding studies, processed oat groats supplied digestible energy and worked as the main grain in complete diets.^1,3,5

2. 02

   Adds fermentable fiber

   The kernel contributes fiber alongside starch. Dogs eating an oat-groat diet had more fecal fermentation products than dogs eating the rice comparison diet.^1,5

3. 03

   Uses a common crop

   Oats are a major food and feed grain grown at scale. Manufacturers can use that supply for the grain portion of a recipe.⁷

How much Dog trials fed diets containing 25% ground rolled oats or 40% oat groats; neither amount describes a usual recipe.^1,2

1. Brands say

   Oats give dogs digestible energy

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A 12-husky study found processed oat groats more digestible than several other grains, and a 10-beagle trial fed a complete diet with 40% groats without poor stool scores. Oats work as an energy source.^1,3

2. Brands say

   Oat fiber improves gut health

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A 10-beagle crossover trial found more fecal short-chain fatty acids with oat groats than with rice. Those are fermentation markers. The short trial did not show that the dogs became healthier.¹

3. Brands say

   Whole oats lower dogs' cholesterol

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A 14-dog trial found lower cholesterol on day 28 with 1% extracted oat beta-glucan. An 18-dog trial feeding whole-oat diets for 4 weeks found no cholesterol difference. The extract result does not prove this claim for whole oats.^2,4

4. Brands say

   Oats release sugar slowly and steadily

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A 10-beagle groat trial found no glucose or insulin advantage over rice. In an 18-dog whole-grain trial, the oat diet produced greater glucose exposure than the wheat diet. The slow-energy promise runs against these results.^1,2
