True for me, I've used the ChronOMeter app in the past (it used to calculate all the micro and micro nutrients of a wide variety of food in different databases, now I don't think the free plan is that complete anymore) and even when I ate only unprocessed or minimally processed (by minimally processing I mean for example simply cooking) whole foods and made everything from scratch I could never get the recommended daily amounts of some nutrients, especially IIRC iron, calcium, vit E, vit D, and depending on the meals I made one or another B vitamin, often thiamine.
Some of this difficulty has to do with our crops being lower in nutrients because the soil itself is (and I think microplastic pollution doesn't help), especially regarding iron and calcium. Nutrient rich plants require nutrient rich soil to grow and are probably more interesting to insects that want a bite, that's why they are often more expensive.
Also difficult to meet the omega 3 and 6 requirements at the same time while staying below 30% of daily calories coming from fats. Vitamin C is easy to get, it's in raw vegs and fruit and the minimum required is ridiculously low, even if I admit I supplement it sometimes because so called megadoses (it's soluble in water so there is no risk of overdoing it aside from digestive issues in sensitive people. I tolerate about 1 g every four hours easily, and vaguely remember the upper limit in general in studies being around 8 grams a day but at some point it's just a way to make your pee more expensive) taken at the onset of symptoms shorten the duration of respiratory infections especially for people whose immune system is temporarily down due to intense exercise (don't take my word for it, check it out and experience it and correct me if necessary, I'm going from memory here)
