Personally, some clients of mine were affected by muscle cramps recently, so let's clarify the reasons behind the topic. The reason behind muscle cramping remains unclear, but there are 3 possible explanations which are:
- muscle fatigue or overexertion
- dehydration, and
- electrolyte imbalance
In addition, high potassium foods like fruits, vegetables, legumes, low fat dairy foods and adequate sodium can eliminate muscle cramps. Try these simple nutritional tips if you are affected by muscle cramps and I think you will be on the right track.
