How to Reduce Sodium Intake
If you think that sodium might be at least partly to blame for your headaches, you can try to reduce sodium intake.
The best thing you can do to reduce your sodium intake is to cook more of your food from scratch. Prepared foods tend to contain a lot of sodium. This includes foods like jarred pasta sauce. Starting with tomato paste as opposed to tomato sauce can make a big difference in your sodium consumption.
Foods prepared at restaurants–especially fast food restaurants–use a lot of salt in preparing your food. You can ask about added salt in your foods and try to avoid foods that have added salt, but you’re probably still going to get more than you would at home.
Use labels to guide you to lower-sodium alternatives. When you do use canned foods, you can also reduce sodium intake by rinsing the food before eating.
