Balance is Key
There are three keys to using the Eatwell Guide:
Balance - Eat foods from all groups of the Eatwell Guide.
Variety - Eat different foods from each food group.
Moderation -Eat more foods from the larger sections,
& fewer & smaller portions of foods from the smaller sections
For years, people held to the idea that there
are bad nutrients and good nutrients when,
in fact, all nutrients play a certain role in the body.
Even those nutrients once considered bad such as fats
and carbohydrates perform vital functions in the body
and if one consumes too many good nutrients such as
vitamins or minerals there can be harmful results, as well.

Positive energy balance
People who are in positive energy balance over an extended period of
time (i.e. they take in more energy than they use) are likely to become
overweight or obese.

Negative energy balance
A person is said to be in negative energy balance when there is insufficient energy from the
diet to meet energy demands of the body. Energy is derived from energy stores and the
person loses weight.
People who achieve a negative energy balance over an extended period of time, are likely
to become underweight.
Underweight can lead to: hair loss, dry, patchy skin, weakened immune system, osteoporosis,
infertility and heart failure

Trans Fats or Hydrogenated Fats
Most people in the UK do not eat a lot of trans fats. On
average, we eat about half the recommended maximum.
Most of the supermarkets in the UK have removed
partially hydrogenated vegetable oil from all their own-
brand products.
People in the UK tend to eat a lot more saturated fats than
trans fats. This means that when you're looking at the
amount of fat in your diet, it's more important to focus on
reducing the amount of saturated fats.

LEARNING
INTENTIONS

Trans Fats or Hydrogenated Fats
Trans Fats are found naturally at low levels in some
foods, such as meat and dairy products.
They can also be found in partially hydrogenated
vegetable oil. Hydrogenated vegetable oil must be
declared on a food's ingredients list if it's been included.
Like saturated fats, trans fats can raise cholesterol levels
in the blood.
The government recommends that: adults should not
have more than about 5g of trans fats a day

Cholesterol
Function in the Body:
Helps the body make necessary cells including skin, and hormones.
Aids in digestion.
The human body manufactures all the cholesterol it needs. You also
get cholesterol from animal food products you eat.
When cholesterol levels are high
there is a greater risk for heart disease.

Scottish Dietary Goal - Fat
Decrease total fats to less than 35% of food energy
Decrease saturated fats to less than 11% of food energy
No increase in Trans fatty acids keep at less than 1% of
food energy
Total Fats
Reduce to approx 650 calories per woman
and 875 calories per day for men.
Saturated Fats
Reduce to approx 200 calories per woman
and 250 calories per day for men.
Editor's Notes
#19: When the diet provides more energy than is needed, it is stored as fat and the person puts on weight over time.
People who are in positive energy balance over an extended period of time (i.e. they take in more energy than they use) are likely to become overweight or obese.
Excess energy is stored in adipose tissue and can build up if energy intake continues to be too high, or activity levels remain too low.
Being overweight or obese is associated with an increased risk of developing certain cancers, cardiovascular disease and type 2 diabetes.
Carrying a large amount of weight/fat around the waist also increases the risk of these health problems.
#20: On the contrary, a person is said to be in negative energy balance when there is insufficient energy from the diet to meet energy demands of the body.
Energy is derived from energy stores and the person loses weight.
People who achieve a negative energy balance over an extended period of time, are likely to become underweight.
#43: A normal LDL level in a teenager should beless than 100 mg/dl,
Total Cholesterol - Less than 170mg/dL
Non-HDL Less than 120mg/dL
LDL Less than 100mg/dL
LHDL More than 45mg/dL
Total cholesterol- a measure of the total amount of cholesterol in your blood. It includes both low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol.
LDL (bad) cholesterol- the main source of cholesterol buildup and blockage in the arteries
HDL (good) cholesterol- HDL helps remove cholesterol from your arteries
Non-HDL- this number is your total cholesterol minus your HDL. Your non-HDL includes LDL and other types of cholesterol such as VLDL (very-low-density lipoprotein).
Triglycerides- another form of fat in your blood that can raise your risk for heart disease
