More causes of the low magnesium epidemic? 23 Oct 2020
In my last blog article, I started to explore how every day food choices and medications were having an adverse impact on our magnesium levels. I now want to take a look at what we drink and ageing.
1. Cola drinks
Most dark colored soft drinks contain phospates, which actually bind to magnesium inside the digestive tract making it unavailable to the body.
2. Caffinated drinks
The kidneys regulate the level of magnesium in our body. Caffine found in tea and coffee caues the kidnesy to release extra magnesium.
3. Alcohol
Alcohol increased the excretion of magnesium by the kidneys.
4. Ageing
Finally if the list wasn't long enough, we need to add one more thing that we can't avoid, getting older. The over 55's are particularly vulnerable to low magnsium. Magnesium metabolism may be less efficient as we grow older as changes to the GI tract and kidneys contribute to older adults aborbing less and retaining less magnsium.
