I'm not usually one for counting, but at the moment I want something to plug my meals into to see if I am missing out on any nutrients.
What is the most detailed software online for this? I could care less about cals or macro ratios, I just want micronutrient breakdowns.
Great for food and keeping log of activities in the journal section but exercise section is a bit useless. Can also set nutrient goals and track weight and stuff.
I use Nutrition Data. If you use their tracking tool, you will get very detailed vitamin, mineral, and fatty acid breakdowns, and you can get the information calculated for the entire meal or day rather than food by food. I find that inputting foods by gram or oz weight as opposed to their averaged sizes makes an enormous difference in accuracy, too.
The only place I know of that lists micronutrients is the USDA food database: http://www.nal.usda.gov/fnic/foodcomp/search/
Not quite as convenient as FitDay or the like, but it does give you a pretty exhaustive breakdown of everything from vitamins/minerals to fatty-acid composition. How accurate their breakdowns are is of course up for debate.
I've used nutriondata.com as well and recently found the cron-o-meter which allows you to plug in your own nutritional goals, like percentage of fat/protein/carbs, calories etc:
None of the sites are exhaustive, for example, I can't find blanched almond flour, so I have to plug in blanched whole almonds instead. And dessicated coconut for coconut flour.
I use MyNetDiary. I really love it. It's quick to enter data. It has an iPhone app that syncs with the online database. Mobile food logging baby! It also keeps track of macronutrients and exports reports to Excel. However, it's not free.
Another one, that I don't see listed is www.sparkpeople.com . It probably isn't the right fit for your particular needs, but is a great site for someone who is completely clueless about nutrition and health... a good starting place, mostly because it eventually got me here ;-)
