One of my sons used to drink a lot of lemonade, which is a very acidic food. We realize now this was a trigger for his nausea, headaches and tight muscles. Besides cutting out the lemonade, we were able to treat him by putting him on an Ayurvedic diet for ulcers to reduce stomach acid. The Ayurvedic diet emphasized magnesium rich, alkaline foods such as raw foods, especially bananas and broccoli, and milk. One home remedy that has worked for me personally to treat the symptoms of headache, cold hands and feet, vertigo and many of the other conditions listed above is to drink a banana smoothie with coconut milk, which is an easily absorbable, alkaline, magnesium rich drink.
