sodium

It depends on you and your blood pressure response. If you have normal blood pressure, you can supposedly safely go up to 2300 mg. If you have high blood pressure, you should limit it to below 1500 mg per day. That is because sodium causes water retention in the form of increased blood volume which increases blood pressure. For people who are trying to control water retention, I recommend sticking to the high blood pressure recommendation of less then 1500 mg per day even if they have normal blood pressure. Then you have people like me who have low blood pressure (This happens a lot to athletes and people who exercise regularly for years because exercise lowers blood pressure over time.) who may need to consume more sodium if their blood pressure drops too much.
