Common Nutrient Deficiencies for Adult Men

5. Calcium

Calcium deficiency occurs when blood levels of calcium are too low. Long-term, this deficiency can cause dental problems such as broken or decaying teeth, osteoporosis, cataracts, generalized muscle aches, and leg pain while walking. Severe calcium deficiency may cause life-threatening symptoms such as heart arrhythmias and muscle convulsions.

The most common cause of low calcium is simply not consuming enough foods with high calcium content, such as milk, cheese, kale, almonds, and sesame seeds.
