According to Health Professionals, nobody. Apparently, we get all of the vitamins, minerals & other nutrients that we need from a "Healthy Balanced Diet" (whatever that is!).
According to me, just about everybody. Due to modern farming methods, food ain't what it used to be. Dammit, even nostalgia ain't what it used to be! Due to changes in lifestyle:-
a) People are more sedentary than they used to be. This means that they require less food than they used to in order to not get fat. Less food, coupled with less nutrients in the food = dietary deficiencies.
b) People don't get as much sun on their skin as they used to, as they now work, play & live mostly indoors and when they do go outside, they are encouraged to Slip Slop Slap (slip on a shirt, slop on sunscreen and slap on a hat). This results in hypovitaminosis D, as only an Eskimo's diet contains enough dietary Vitamin D. The RDA of 200/400/600iu/day (depending on age) is woefully inadequate and totally out of touch with modern research.
c) Many people don't eat much oily fish. Also, animal & vegetable produce now contains more omega-6 & less omega-3 than it used to. This can result in a large imbalance. I eat two 120g cans of mackerel in spicy sauce a day. This also provides protein.
d) Diets low in dark green vegetables & fruits lack Magnesium & Potassium.
e) Diets low in fermented foods lack Vitamin K2.
I currently supplement with:-
400mg/day of Magnesium, as 4g/day Epsom Salts dissolved in water & the solution added to drinks.
5,000iu/day of Vitamin D3.
15mg/day of Vitamin K2.
