Subbing, but I'm not sure one exists. WAP values are kinda anti-nutritionism. Food is the basic unit of nutrition, not individual nutrients. Whole foods, such as raw milk, provide nutrition in ways that allow macro- and micronutrients to be absorbed and assimilated best. When I was pregnant, I was taking almost 200% the RDA of calcium through supplements including prenatal vitamins, enriched soy milk, and calcium magnesium citrate. However, I was calcium deficient, and my daughter now has cavities as a result. I am now rebuilding our health, and we get enough calcium through kefir, cheese, bone broth, vegetables topped with butter, minimizing antinutrients such as phytic acid, getting enough fat and fat-soluble vitamins (as cofactors for the minerals such as calcium), etc. As you can see, it goes far beyond getting x mg of calcium per day to how I can make sure we have a healthy calcium status.
An unfortunate side effect of making statements about how much of any particular nutrient people need in a particular time frame is that it becomes a marketing statement for companies creating processed foods. Candy is marketed with "100% daily value Vitamin C," Goldfish are now made with "whole grains," and Vitamin water is promoted as being a healthy way to get some extra vitamins.
Still, it would be nice to know if we're getting enough of all the right nutrients. Dr. Price studied healthy cultures, but it's not like we can totally recreate the diet from one of those cultures here. Additionally, most ate seasonally, so they would be getting different amounts of nutrients at different times of the year. I don't think that the US RDA's are bad amounts to shoot for in general. I've seen one WAP recommendation that you multiply the fat soluble vitamin RDA's by 10. I try to make sure I'm getting at least as much as the RDA's through well prepared foods, but if anybody has better info, I'd love to see it.
