  3. Brief History of Salt

  4. Assignment • The salt-o-meter SO what? Does this change your behavior? Why or why not?

  5. Why is Salt a bad thing? Salt leads to water retention Too much water throws off your renal system (kidneys) This leads to high blood pressure

  6. Kidneys • Your body removes unwanted fluid by filtering your blood through your kidneys • To do this, your kidneys use osmosis to draw the extra water out of your blood • This process uses a delicate balance of sodium and potassium to pull the water across a wall of cells from the bloodstream into a collecting channel that leads to the bladder • Eating salt raises the amount of sodium in your bloodstream and wrecks the delicate balance, reducing the ability of your kidneys to remove the water

  7. Results? • The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys • This could lead to kidney disease

  8. Arteries • strain on the insides of your arteries • walls become stronger and thicker • blood from the arteries become starved of the oxygen and nutrients they need

  9. heart • angina (sharp pains in the chest when being active • not receiving enough oxygen and nutrients • arteries burst or become completely clogged • The result is a heart attack

  10. brain • Reduced blood flow to brain • Over time could lead to dimensia • Worst case - stroke
