Men consuming 523 mg of dietary magnesium per day 6% MORE likely to die over 10 years vs 387 mg

The one-third of men consuming the most dietary magnesium -- an average of 523 mg per day -- were 6% MORE likely to die over the next 10 years compared to the one-third of men consuming the least dietary magnesium -- an average of 387 mg per day -- according to a study that followed 23,366 Swedish men, aged 45–79 years, who were NOT taking dietary supplements.
However, this difference was not statistically significant which means it could have been due to random chance.
Death from Cardiovascular Disease (CVD)
25% GREATER risk of death from CVD over 10 years in those consuming the most magnesium
“Dietary magnesium intake—the top one-third of men consuming an average of 527 mg vs the bottom one-third consuming an average of 387 mg—was not associated with all-cause, CVD [Cardiovascular Disease], or cancer mortality,” the paper notes.
Table 2 in the paper shows that the top one-third of men consuming the most magnesium—an average of 527 mg per day—were 25% MORE likely to die than the one third of men consuming the least—an average of 387 mg per day.
This result was close to being statistically significant.
There was a 9% chance that this difference could have been due to random chance, but this also means that there was a 91% chance that the increase in death from cardiovascular disease was due to the difference in magnesium intake.
It is close enough for me to stand up and take notice.
Comment: This finding was the OPPOSITE of what I expected
This finding on magnesium was the OPPOSITE of what I expected
This finding that a higher intake of dietary magnesium was associated with a 25% INCREASED risk of dying from cardiovascular disease over 10 years was the exact OPPOSITE of what I expected.
This study also found that the one-third of men consuming the most calcium—an average of roughly 2000 mg per day—were 25% LESS likely to die over 10 years than one-third of men consuming the least calcium—an average of roughly 1000 mg per day.
