First, a song by someone who should be alive, but isn't...
The above video was inspired by a Facebook friend who had an accident with Schwartzkopf black hair dye and spent ages getting the stains off her skin. You know who you are!
I may have mentioned that nutrient deficiencies can adversely affect mental (and/or other) function. Nowadays, many people live on a diet of Crap-In-A-Bag (CIAB). There's just enough essential amino acids (EAAs), essential fatty acids (EFAs), minerals & vitamins to keep their bodies alive. However, Alive ≠ Working properly.
To compensate for one (or more) nutrient deficiencies, many people are prescribed one (or more) pharmaceutical drugs to tweak how their brains work e.g. fluoxetine, citalopram/escitalopram, venlafaxine, quetiapine, risperidone, valproate etc. There are no pharmaceutical drug deficiencies!
There are people who suffer from mental (and/or other) illnesses, despite having diets & lifestyles that provide sufficient amounts of all nutrients. This post isn't about them. There are people who suffer from depression due to traumatic & inescapable events/situations. This post isn't about them, either.
Finally, nerds! We nerds love to compile information. For an interesting interview with a top compiler of useful information, see Examine's Supplement Goals Reference Guide.
For an excellent article with a mere 148 references, see Why Calories Count. To sum up:-
Where body weight is concerned, calories count (but don't bother trying to count them).
Where body composition is concerned, partitioning counts.
Where health is concerned, macronutrient ratios, EFAs, minerals, vitamins & lifestyles count.
N.B. Poor health can adversely affect body weight and/or body composition, by increasing appetite and/or by adversely affecting partitioning.
