i haven't read this study. how did they initiate depression and anxiety in the mice? i remember one study where they induced depression in mice by making them magnesium deficient.
in conclusion the researchers recommended using magnesium deficiency in mice as a way to study different depression treatments.
of course that older conclusion made me laugh, but this study brings in the connection between healthy gut flora and magnesium absorption (magnesium is mostly absorbed in the small intestine).

"Colonic microoganisms also play a part in vitamin synthesis34,35 and in absorption of calcium, magnesium, and iron.25,36,37"
a few more tidbits about diet, gut flora and nutrition...
Phytate breakdown and apparent absorption of phosphorus, calcium and magnesium in germfree and conventionalized ratshttp://www.sciencedirect.com/science/ar ... 1796000383
"... the presence of gastrointestinal microflora did not increase phytate breakdown, which means that gastrointestinal microflora play no major roll in phytate breakdown in rats. ...Comparison between rats fed the phytate-free diet and those fed the phytate-containing diets made clear that ...dietary phytate decreased apparent absorption of Mg but not that of Ca.
now that is very interesting. i knew all about phytates impairing zinc absorption, but i hadn't realized the effect on magnesium absorption.

"Changes in food habits in Western countries that no doubt constitute stresses to the human body and that may predispose to inflammatory, infectious, ulcerative, degenerative, and neoplastic diseases include the following: the consumption of 100 lb refined sugar per individual per year; the 10-fold increase in sodium consumption; the fourfold increase in consumption of saturated fat; the doubled consumption of cholesterol; a much reduced consumption of vegetable fibres, and of minerals such as potassium, magnesium, calcium, and chromium; and a considerable reduction in consumption of n-3 fats, membrane lipids, vitamins, and antioxidants..."
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
