What is the percentage of sodium in a pint of blood?daily value?then why is it bad for you&cause high presure? thank you.

Sodium Requirements: Daily intake sodium should be no more than 2300 mg daily (one tsp of table salt!) your question is far too simplistic and the complex regulation of electrolytes in the body requires a lot of learning even for medical students. You might broaden your understanding of health issues at sites like: http://www.Nhlbi.Nih.Gov/ trying to "figure it out" yourself might be dangerous to your health.

Water retention: Normal level of sodium is about 140 meq/l. Salt/sodium is essential for health, but many people respond by retaining excess water and rise in blood pressure with intake of more sodium than needed. There is no harm in not adding salt to your food, unless you are sweating excessively.
