A food or beverage composition suitable for human consumption includes an aqueous suspension such as cow's milk that has been supplemented and homogenized with an omega-3 fatty acid-containing supplementation oil, in which a supplementation oil includes a blend of an omega-3 fatty acid-containing enriching oil that has been combined and diluted with an oxidative stabilization oil, such as a low linoleic acid/high oleic acid-containing oxidative stabilization oil. As a result, the rate of oxidation of EPA/DHA fatty acids added to the aqueous suspension via the supplementation oil can be reduced substantially, e.g., at least two-fold or even much more compared to the rate of oxidation of an equal quantity of the same EPA/DHA fatty acid-containing enriching oil homogenized into the same aqueous suspension without having been first combined and diluted with the oxidative stabilization oil.
