Title: Nutrition Labelling and Prevention of High Blood Pressure
1Nutrition Labelling and Prevention of High Blood
Pressure
2High Blood Pressure
1 in 3 men have high blood pressure -
- According to a local survey conducted in
2003/2004, about 1 in 3 men and 1 in 4 women in
Hong Kong have high blood pressure. - People with high blood pressure may not know at
its early stage of development and yet untreated
high blood pressure can lead to heart attack,
stroke, kidney failure, etc.
1 in 4 women have high blood pressure -
3Dietary Modifications for High Blood Pressure
Prevention
- Lower the intake of sodium can reduce the risk of
developing high blood pressure. - Lower the intake of saturated fat and trans fat
can reduce the risk of developing heart diseases. - Choose foods with lower energy, fat and sugars
contents for those who are overweight.
4Preventing High Blood Pressure and Nutrition
Labelling
- Using nutrition label can help us to find out the
sodium content of food products.
5Read and Use Nutrition Labels
6Examples of Recommended Format of Nutrition Label
Tabular format
7Examples of Recommended Format of Nutrition Label
Linear format (for small packages with total
surface area of less than 200 cm2)
8Required Nutrients on Nutrition Labels
- 17 (energy plus seven nutrients specified for
labelling) i.e. energy, protein, total fat,
saturated fat, trans fat, carbohydrates, sugars
and sodium. - Nutrient(s) involved in nutrition claim(s) (when
the nutrition claim is on any type of fat, the
amount of cholesterol must be declared as well). - For other nutrients, declaration is voluntary
9Making Use of Nutrition Label
- Consumers can
- Compare the nutritional content among different
foods for a healthier choice, e.g. choose food
that is lower in fat, sodium (or salt) and sugars - Understand the nutritional content of food and
estimate their contribution to the overall diet - To meet individuals dietary needs
10Three Simple Steps toRead Nutrition Label
11Three Simple Steps toRead Nutrition Label
- Step 1Â
- Take note of the reference amount of food being
used in the nutrition label - Step 2Â
- Read the energy and nutrient content together
with the reference amount - Step 3Â
- Refer to the percentage Nutrient Reference Value
(NRV), if available, to see if the food contains
a lot or a little of energy or a nutrient in the
food
12Step 1 Take note of the reference amount offood
being used in the nutrition label
- Expressed as per 100 g (or per 100 mL) of food
13Step 1 Take note of the reference amount offood
being used in the nutrition label
- Expressed as per serving (the serving size (in g
or mL) and the no. of servings must be specified
on the package)
14Step 1 Take note of the reference amount offood
being used in the nutrition label
- Expressed as per package (if the package contains
only a single serving )
15Step 2 Read the energy and nutrient content
together with the reference amount
- Use nutrition label to compare between products
- Use nutrition label to calculate the amount of
energy and nutrients you get from food
16Step 2A Use nutrition label tocompare between
products
- Products with nutritional content expresssed in
the SAME reference amount
If reference amount is the SAME, you CAN COMPARE
between the products DIRECTLY
17Step 2A Use nutrition label tocompare between
products
- Products with nutritional content expresssed in
DIFFERENT reference amounts
If reference amounts are DIFFERENT, you CANNOT
COMPARE between the products DIRECTLY
18Step 2A Use nutrition label tocompare between
products
- Products with nutritional content expresssed in
DIFFERENT reference amounts
19Step 2BUse nutrition label to calculate the
amount of energy and nutrients you get from food
- The more you eat, the more you get
- If you eat 1 serving of biscuit
- Get 8 g of fat, 3.5 g of saturated fat
- If you eat 2 servings of biscuit
- Get 16 g of fat, 7 g of saturated fat
20Step 2BUse nutrition label to calculate the
amount of energy and nutrients you get from food
- Energy and nutrient content expressed as per 100
g/mL
21Step 3 Refer to the percentage Nutrient
Reference Value (NRV), if available, to see if
the food contains a lot or a little of energy or
a nutrient in the food
- NRV is usually on a scale from 0 to 100.
22Step 3 Refer to the percentage Nutrient
Reference Value (NRV), if available, to see if
the food contains a lot or a little of energy or
a nutrient in the food
- For nutrients that needed to limit their intake
- E.g. total fat, saturated fat, sodium and
sugars - Look for foods that have lower NRV
- Get enough of nutrients that are good for health
- E.g. dietary fibre
- Look for foods that have higher NRV

25Principles of Healthy Eating
- Choose a variety of food and eat cereals as the
largest portion of food in every meal. - Eat a lot of vegetables and fruit.
- Reduce the consumption of foodstuffs with high
salt, fat and sugar content as well as those
which are preserved. - A daily fluid intake of 6 to 8 glasses (including
clear soup, fruit juice and tea). - Take meals regularly and in adequate amounts.

26Nutrition Labelling is a Useful Tool for
Practising Healthy Eating
- Nutrition label and nutrition claim can help
consumers choose healthier food in accordance
with healthy eating principles and the Food
Pyramid, e.g. - Choose biscuits lower in fat and sodium (or salt)
- Choose dairy products lower in fat
- Choose beverages lower in sugars
27How to Choose Prepackaged Foodto Prevent High
Blood Pressure?
28Preventing High Blood Pressure Choosing
Prepackaged Foods
- Take note of relevant nutrition claim as a quick
screening tool and - Take three simple steps to read nutrition label
-
29Preventing High Blood Pressure Choosing
Prepackaged Foods
- Choose foods with lower sodium and combined
amount of saturated fat, trans fat. For those
who require weight maintenance, choose foods with
lower energy, fat and sugars contents - Nutrition claim only gives a rough idea about the
content of a particular nutrient, one should not
make a food choice solely on the basis of a
nutrition claim. In order to eat healthily, we
should take note of other nutrients as well. For
example, when buying a product with a low
sodium claim, one should take note of the
content of fat and other nutrients.
30Preventing High Blood Pressure Choosing
Prepackaged Foods
Nutrient content claims on sodium are classified
into Free, Very low and Low claims Specific
Conditions of Nutrient Content Claims -
Claim Free No Zero Without Does not contain Claim Very low Extremely low Super low (This category of claim applies to sodium only) Claim Low Little Low source Few Contains a small amount of
Meaning of Claim Insignificant amount of a particular nutrient found in the food Meaning of Claim A very small amount of sodium found in the food Meaning of Claim A small amount of nutrient found in the food
Example Sodium free (Contain not more than 5mg of sodium per 100g/mL of food) Example Very low sodium free (Contain not more than 40mg of sodium per 100g/mL of food) Example Low sodium free (Contain not more than 120mg of sodium per 100g/mL of food)

36Is Salt the Same as Sodium?
- Sodium chloride (NaCl) is the chemical name of
salt - Majority of sodium intake is from salt
- Salt or other sodium-containing food additives,
e.g. sodium nitrate and sodium nitrite, are often
added to canned food and processed food - Sodium itself also presents naturally in milk and
cheese
37How Much Sodium Do We Need?
- The World Health Organization (WHO) recommends -
- The daily intake amount of sodium should not be
more than 2 000mg - i.e. approximates to 1 level teaspoon of salt
