CRAZY I guess I almost lost this post I just spent forever writing :S glad I snagged it to the clipboard! here it is, round two:
OK this is info I can use
consider making a bag of frozen mixed fruit a regular purchase. perhaps you could alternate between eggs and oatmeal at breakfast?
a bag of apples wouldn't do any harm either.
the beef pork and chicken rotation sounds good. any chance of working some other seafoods into the tuna rotation? like frozen salmon, or tinned oysters or clams?
that's a lot of mayo - how does that factor in? tuna salads?
broccoli and cauliflower, mushroom, tomato, onion, flax = awesome!
re the frozen mixed veg, glad to see spinach in there. better option than peas and carrots, although the last two are nice for variety
ever consider yams / sweet potato? so nutritious and anti inflammatory
the dairy ration sounds ok
DITCH THAT DIET COKE too much phosphorus. ties up nutrients. how do you feel about herbal teas?
you're off grains and legumes entirely by the looks of it - smart to reduce processed flour products. but on the whole food front, you could be throwing out the baby with the bath water to some extent. ever pick up brown rice and/or wild rice?
anyway. I won't comment on the supplement regimen now except to recommend a solid 1 week washout before you go for any nutrient testing.
as for tests, you have mentioned serum 25(OH)vitamin d3, serum zinc and serum magnesium. couldn't hurt to also test serum ferritin and serum copper. and serum cobalamin, just to see how your supplement is doing. be sure to get your own copy of results
