Health effects of dietary sodium

  1. 1. HEALTH EFFECTS OF DIETARY SODIUM J.A.C.M.JAYAKODY
  2. 2. Na is a mineral  A kind of salt  Very essential  Body can’t manufacture  Should provide from out side  Most common form is sodium chloride SODIUM
  3. 3. Sodium chloride is the common source. Some of others are  Monosodium glutamate  Sodium nitrate  Sodium saccharin  Sodium bicarbonate  Sodium benzoate SOURCES OF SODIUM
  4. 4. Through out five basic taste only NaCl leads to unique saltiness. Sodium level  According to early experiences  Enhance the natural flavor  Vary with the type of food Taste and sensory
  5. 5. Preserve foods  Inducing dehydration  Reduce microbial growth Bacteria resistant highly. Halopilic bacteria • listeria monocytogenes • Staphylococcus aureus • Vibrio parahaemolyticus Preservation and safety
  6. 6. Control the fermentation  bread dough - yeast  pickling Texture aid  bread dough - strength gluten - hold more water and CO2  pickling - draw moisture out - increase crispiness and firmness Stabilize the egg white OTHER EFFECTS
  7. 7. sodium sources in the diet Heat resistant 1 teaspoon 2,300mg of sodium DIETARY SODIUM
  8. 8. Adequate intakes (mg/day) Tolerable upper intakes (mg/day) Infants 0-6 months 120 Not determine 7-12 months 370 Not determine Children 1-3 years 1000 1500 4-8 years 1200 1900 Male/female 9-50 years 1500 2300 50-70 years 1300 2300 >70 years 1200 2300 Sodium requirements
  9. 9. A vital component of all fluids- blood and sweat Important role in  Maintaining water balance within cells  Function of nerve impulses and muscles  Enzyme operation HEALTH EFFECTS OF DIETARY SODIUM
  10. 10. High blood pressure 120/80 - normal level 140/90 or above – hypertension HYPERTENTION Primary Secondary No identifiable cause Caused by an underlying conditions Develop gradually over many years Appear suddenly
  11. 11. Reasons  Higher sodium intake  Inadequate intake of K, Ca and Mg Higher alcohol consumption Excess body weight Controlling  Diet rich with fruits and vegetables Reduce dietary fat consumption  Physical activities
  12. 12. Renal diseases – can’t eliminate excess Na and fluid from body Reduce function of kidneys Hypertension affects on kidneys Control by  Control blood pressure Control thirst and fluid in take EFFECTS ON KIDNEYS
  13. 13. Level of sodium abnormally low Due to imbalance of water and sodium Symptoms  Headache, nausea, vomiting Critical- seizure coma or death Controlling  Monitoring urine color HYPONATREMIA
  14. 14. Four groups Industries  alternatives for preservatives  Low sodium foods Government  Rules for sodium level Advertising SODIUM REDUCTION
  15. 15. Individuals  more fresh foods Make foods our own Require low sodium foods
