I have celiac and it's amazing how big of a deal being low in one (or more) vitamins can be. I have gotten deficient often enough that I can almost recognize each type of tiredness from my most common deficiencies. Being tired from anemia/low iron is definitely different than being tired from a vitamin b deficiency, for instance. And being simultaneously deficient in vitamins that work together - like calcium and magnesium, or vitamins a, d, e, and k - also feels different than being deficient in just 1 of these vitamins.

When people tell me they crave a lot of certain foods, that's a sign that their body wants whatever vitamin is in that food. If your body hasn't tried a lot of other healthier foods, it won't have learned their nutritional content and won't crave it. Potatoes (in potato chips) contain small amounts of metals like copper, zinc, lithium, iron. Corn similarly has vitamins, I do not eat much corn so idk what all it has in it.

However, just because you're getting a tiny bit of zinc from a whole bag, doesn't make the chips good for you. They come with other nutrients including sodium which are excessive and should be balanced with a good potassium intake (like a bottle of coconut water). Your body isn't meant to process huge loads of wasteful food, and that comes at a price. Eating more efficiently with more nutrient dense foods is best (especially dark leafy greens which contain chlorophyll which can actually make ATP in your blood stream for basically "free" - free energy).

Last, we all have different genetics. Not all of us need the exact same diet or vitamins. Some of us literally need extra vitamin A (do you have genes from either the north or south pole, such as Russian or Native American? You might want to take slightly extra vitamin A along with other fat soluble vitamins like vitamin D). And every vitamin is like this, some being more serious than others. Some people can't eat much tyramine without developing possible life threatening brain bleeds and high blood pressure. Olives contain tyramine as does certain types of red wine - many cultures eat these in volume and have no problem but some people just can't.

"You are what you eat" ended up being real wisdom
