Unfortunately, some of these items are things for which you just can't rely on the tracker to see how much you are getting. Those that aren't mandated by law to be shown on the packaging won't be included in the nutrition information for those foods, even if the food actually contains them.
The items actually updated by SparkPeople do contain the info, based on the USDA site, or you can check that site yourself for more info: www.ars.usda.gov/Services/docs.htm?docid=2
Another site that I find useful for getting this info is: nutritiondata.self.com/
For the nutrients which are important to me but are not listed, I get the info from these two sites and add it in to an entry for that food which I create for myself. This way I'm getting at least a slightly more accurate look at what nutrients I'm getting.
If you eat spinach, broccoli, asparagus, or other greens, then you are likely getting more of these nutrients than the tracker suggests. You might want to double-check the entries that you are using to see whether they actually include the info on the nutrients you are looking at.
You could add some salmon to your diet (a 55g serving is 12g of protein and 15% RDA of calcium). For folate, you can look at cereals or pastas that are fortified with it, or go for asparagus and spinach. For potassium, there is a surprising amount in most veggies (I was happily surprised how much in carrots).
Hope this helps!
