Ahh, ok your assuming nutrients all need to hit exactly 100% each day to be heathy. The reality is perfection changes with age, Heath issues, pregnancy, sun exposure, body weight, and a host of other issues. However, close enough is plenty to stay in good heath. So, while there is no diet that works equally well for a nursing mother and a sedendary accountant both can stay heathy eating just rice and a multivitamin or enshure and some empty cal.
No, I am not assuming anything. I gave you a specific real example of an actual problem. Do you have anything constructive to add to the discussion, or did you just want to provide an example of the kind of deliberately dishonest hand-waving I was referring to?
The Manganease recommendation is based on observed western diets not actual need. From existing studies it looks like there is a fairly wide tolerable range for Manganease with some people needing quite a bit to maintain Manganease levels. Anyway, 5x ensure is well within the 'Tolerable Upper Limit' and thus Not an issue.
Except that most people get a significant amount of manganese from their water, thus putting them at risk. This is what I said in my post, which you should read before you reply to.
Sorry, assuming you drink water still. does not read as assuming your water has unusual concentrations of Manganese. Even still, known heathrisks relate to breathing excesive Manganease as it's normally excreted though the gut not the urine.
Edit: If it's really bothering you. Ambient manganese concentrations in seawater have been reported to range from 0.4 to 10 μg/l (ATSDR, 2000), with an average of about 2 μg/l (Barceloux, 1999). Levels in fresh water typically range from 1 to 200 μg/l (Barceloux, 1999). ATSDR (2000) reported that a river water survey in the USA found dissolved manganese levels ranging from <11 to >51 μg/l. The United States Geological Survey’s National Water Quality Assessment Program has gathered limited data since 1991 on representative study basins around the USA. These data indicate a median manganese level of 16 μg/l in surface waters, with 99th-percentile concentrations of 400–800 μg/l (Leahy & Thompson, 1994; USGS, 2001). Higher levels in aerobic waters are usually associated with industrial pollution.. (http://www.who.int/water_sanitation_health/dwq/chemicals/man...)
So, again there may be people that need to be consurned to it's less than 1% of the population and they can get buy by drinking bottled water if nothing else.
No, the high end of the 99th percentile is 800 μg/l or .8mg/ liter. 2 liters per day of water is 1.6mg/ day and the TUL is 11mg/ day. Thus adding 50% from ensure and 1.6 / 11 = 14.5% from unusually high water levels is at worst 64.5% TUL and again not a problem.
