i have read in different places it does, but even healthy fats?

i know healthy fats have slowed down my digestion a lot

Jamie, because it flushes it out of your system. Or so I've read. Same thing with potassium.

Its contraversial science. However, it kind of makes sense (but not really), in a very high fat diet. Magnesium is water soluble. One thing to consider, is that fluid and electrolytes in general are more heavily taxed on low carb. It could be just that your not eating enough electrolyte foods (part magnesium) for your carb intake?

Most tap water has some magnesium in it. Not as much as river water, but theres still some in there (more than spring water FYI). Why would too much water reduce magnesium levels btw?

thank you! I am going to assume my problem is from drinking too much water

i am not on birth control but i have a connective tissue syndrome. i think people who have that are predisposed to hormonal fluctuations and malabsorption. the dyautonomia is what makes me thirsty. i will try drinking less water tho!! i def drink more than 8 glasses a day.

good point, i figure most people here have good mg levels. mine are terrible. i wonder if it's the fat or my body isn't used to eating fat..or i drink too much water, the list goes on and on!!

the effects of dietary components on magnesium absorption probably are critically important only at low intakes of magnesium -- http://ukpmc.ac.uk/abstract/MED/1496118

in response to your 1918 study there is nothing in there that explains how the experiment was conducted, so it's hard to accept the results. http://pediatrics.aappublications.org/content/61/4/537.short

why do you feel healthy fats slowed down your digestion? fat makes you more sated for longer, but fat actually increases gastric motility (transit time through the intestine). and what's the link between this and magnesium?

Never heard of this....I have heard of antinutrients in grains and legumes binding minerals blocking their absorption, but never about fats. Do you have a link?

No. This falls into the category of A causes B and B causes C so then A causes C.

This is not the case. Yes, increased fat consumption will increase the speed in which you digest and excrete foods. Yes, Magnesium is primarily absorbed in the small intestine. But NO, increasing the speed in which food passes through your small intestines will not reduce it's ability to absorb the nutrients.

So what would contribute to reduced magnesium absorption (other than disease and genetic mutations)?

The primary culprits are:

  • insoluble fiber (which both speeds up bowl movements, but more importantly has anti-nutrients which bind to magnesium and prevent their absorption).
  • And Zinc. Too much zinc can cause your body to reduce it's absorption of magnesium. To be clear, zinc is not bad. Too much zinc can be an issue.

    It's possible that you drink too much water. You need about the equivalents of 8 glasses of water a day, but that's not just from drinking, that includes your food sources too. So if you are eating a decent number of veggies and fruit, you would be drinking less than 8 glasses of water. You can always try cutting back a few glasses a day, and if you don't feel dehydrated, see how that helps. Women are more inclined to magnesium deficiency, but I'm not sure why that is. Could be a hormonal thing? Are you on any birth control? Assuming female from your name.

    My magnesium levels are great, according to my doctor. I eat high fat- I usually add some ghee to whatever I am eating in order to get enough calories.
