Why this page doesn't claim "Walnut works"
Whole foods almost never have RCTs — the evidence sits on the ingredients. So this page does one honest thing: it lists which graded ingredients Walnut contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Walnut itself.
Bottom line: The walnut's "omega-3" is the plant-based ALA, which converts very inefficiently into the EPA/DHA found in fish oil (about 5-10%) - it can't be equated with the omega-3 from fish. Copper and magnesium make a small contribution.
