Does anyone stick to their recommendations?

Slavishly? No.

I'm pretty consistent on the big items, which for me are protein and fats. I get a certain minimum of each. (Many people around here just look at protein. I'm one of the rare weirdos who will underconsume fats if I don't pay attention. I gather that's uncommon.)

I care about fiber, but get enough and more without giving it much thought, just via personal food preferences.

I care about micronutrients (and some other things, like food-probiotics and pre-biotics). The micros are not well tracked by MFP, largely because of labeling limitations affecting the database. Mostly, I deal with this by striving to get quite large amounts of varied, colorful veggies and fruits (5+ 80g daily servings minimum, ideally 10+). Every once in a while, I spot-check some nutrients that MFP tracks poorly, by taking a closer look at the micronutrient profile of a typical day or two in my diary. Sometimes, that's as easy as (for example) looking up high potassium foods, and finding I have a number of them already in my diary, but listed as zero potassium because of the labeling issues.

People who are more concerned or want to be more detailed sometimes choose to log at Cronometer instead, though I gather it has its own pros & cons.

I don't worry about being over water-soluble vitamins from food, and have looked up issues with the fat-soluble ones (A, D, E, K) to know whether overdosing is a concern with my typical eating profile. The only micro I've discovered (so far) that I need to be careful to avoid overeating is selenium. The gap between needed amounts and excessive amounts is relatively narrow (compared to most other nutrients), and one food I really like (brazil nuts) can be a surprisingly easy way to reach a questionably-safe level, with fairly modest consumption. If I eat these regularly and often, it's like one a day, even though taste-wise I'd happily eat a handful daily. Bad plan!

Usually, most people following a generally well-rounded diet, and not mega-supplementing, are doing fine. It may make sense to ask your doctor to run a nutritional panel now and then, for key items.

(One observation: I've noticed that some - I don't know what term to use here - health-food-style (?) multivitamins or supplement powders will include kind of remarkably high amounts of certain micronutrients. I'd suggest reading labels and thinking about the implications of supplements in the context of your diet, if you use any of these types. Not saying they're bad, but I feel like some people take them without thinking over the implications. Jane mentioned preformed Vitamin A, for example. That's the form in most supplements, and we can overdo it. It can be kind of easy to get large-ish amounts if using just the wrong combo of a robust multivitamin plus a meal replacement drink plus a vitamin-enhanced superfood supplement, or variations on that theme, just to make up an example.)

A second observation: For most nutrients - all of them I can think of, at the moment - it's really unnecessary to hit them exactly every single day. A little over sometimes, a little under others, not persistently under on the same one most of the time (or persistently over on ones that can be risky) - that's all fine, if the overall average is pretty good, IMO.

Just got my annual blood test "panels" back and everything is w/in spec
