I just meant that, concerning calcium and iron, on the Nutrition Facts label they list these two nutrients (along with a few other nutrients) at the bottom. But they don’t tell you the amounts in terms off grams, mg, mcg etc. Instead, they list them is as a percent of RDA for the nutrient. Unfortunately, the RDA they use is a really old one (from 1968). You can look it up by going to the wikipedia page I linked to. The oil you listed, had calcium and iron percentages on the label. So, to figure out the amount of each in it, you just multiply the percent times these old RDA values. The RDA for calcium hasn’t changed. It’s still 1000mg. So .08 x 1000 = 80mg. But the RDA for iron has changed. It was back then 18mg. So, .02 x 18 = .36mg. So, that means the oil has 80mg of calcium and .36mg of iron.
You could also use the nutrition data they have at http://nutritiondata.self.com, as I linked to, or at the USDA’s nutrient database (http://ndb.nal.usda.gov/ndb/search/list), and these will give you give you typical nutrient profiles for different foods. But nutrient content can vary somewhat from product to product; so it’s best to get as much info from the product’s own nutrition label and then try to fill in the rest of the data from these other resources. The USDA is particularly thorough since it lists things like the different amounts of all amino acids, different amounts of different types of fatty acids, amounts of different carotenoids that aren’t usually listed like lycopene and lutein, and more. For us Soylent DIYers, this can be useful info.
