Essential nutrient deficiencies Re: Addiction to exercise

Addiction to exercise and essential nutrient deficiencies.

Addiction to exercise can be a common problem.1 Deficiencies of essential nutrients, especially of zinc and magnesium are also common and adversely impair brain and body functioning. Even mild isometric exercise impairs muscle function if cellular magnesium levels, measured in red blood cells, are low resulting in prolonged irregular muscle contractions.2 Zinc and magnesium deficiencies also play an important part in osteoporosis.3
Although the human race evolved to do hard physical work, stone age diets usually supplied enough essential nutrients. In contrast, modern diets of mostly high allergy addictive foods can be poor in essential nutrients and also can interfere with absorption of essential nutrients.4 Use of exogenous hormones can also cause mineral deficiencies and imbalances.5
