What is Sodium? Sodium is the main positive ion (cation) in the fluid surrounding cells in the body.
the main source of sodium in the diet is Common table salt or sodium chloride which is 40% sodium and 60% chloride<br>
05
Functions of Sodium in the body Most of the body’s sodium is in the blood and the fluid around cells. For good health our bodies need sodium to help:
maintain red blood cells
regulate and maintain fluid balance
regulate and maintain acid-base balance
Maintain normal nerve and muscle function
the heart to beat normally<br>
06
Sodium needs in the body Our bodies only need tiny amounts of sodium to function
(200 to 500 milligrams)
Sodium needs increase with increased sweating from hot days or heavy physical activity<br>
07
BUT
We consume far more
salt and sodium than we need
and
this can harm our bodies<br>
08
Harmful effects of excess sodium Too much salt in the diet can cause CARDIOVASCULAR DISEASE
through raised blood pressure from fluid retention and build up in the body.
Lead to STROKE AND HEART ATTACK<br>
09
Harmful effects of excess sodium Too much salt in the diet can cause KIDNEY DISEASE by
reducing their capacity to remove unwanted body fluid
increasing the amount of protein in the urine
Increasing formation of kidney stones<br>
10
Harmful effects of excess sodium Too much salt in the diet can increase risk of STOMACH CANCER by
increasing the growth and action of the bacterium Helicobacter pylori (H. pylori. )
Acting as an irritant and inflammatory agent on the stomach lining exposing it to cancer- causing agents (carcinogens)<br>
11
Harmful effects of excess sodium Too much salt in the diet can DAMAGE BONE HEALTH by:
increasing calcium levels in the urine
Increasing calcium loss from bones
Increasing the risk of bone demineralisaton and OSTEOPOROSIS<br>
12
Using less salt and sodium is critical to controlling blood pressure,
and reducing damage to
heart, brain and kidney, stomach and bone health in our population<br>
13
Maximum levels of SODIUM intake The daily recommended maximum level intake in healthy adults is
2 grams or less of sodium
THIS equals about (5 grams) or one level teaspoon of table salt<br>
14
SODIUM guide for hypertensives High blood pressure in most black Caribbean and elderly people tends to be sensitive to salt
SO

33
Use more potassium rich foods Potassium helps regulate fluid balance and blood pressure in your body
low potassium levels may increase risk of raised blood pressure so increased intakes of foods rich in potassium are recommended
Getting enough potassium may help lower your blood pressure.<br>
34
potassium needs The World Health Organization (WHO) recommends MINIMUM potassium intake for healthy adults as follows:
At least 3,510 milligrams (mg) daily
This is even higher for hypertensives on the Dietary (DASH) diet
At least 4,700 milligrams (mg) daily
It is best to get potassium from food instead of supplements.<br>
35
Use more potassium rich foods Try these potassium-rich foods:
Potato: 926 mg
Sweet potato: 540 mg
Small banana: 467 mg
Tomato: 400 mg
1/2 Avocado: 345 mg
