Carbohydrates
Proteins
Vitamins
Minerals
Fats
Water
CARBOHYDRATES
CARBOHYDRATES
The starches and
sugars that provide
the body with most of
its energy. Great
source of fiber.
2 types of CARBS.
1. Simple
2. Complex
SIMPLE CARBOHYDRATES
Simple
Carbohydrates
found in fruit, sugar
and milk
COMPLEX CARBOHYDRATES
Complex
Carbohydrates
found in starchy
foods, breads,
cereals, dry beans,
potatoes, and other
starchy vegetables
PROTEINS
PROTEINS
Needed to build, repair, and maintain body
cells and tissues(particularly muscle).



Provide energy
Especially important during growth periods
(childhood, adolescence, …).
Meat, fish, poultry, eggs, milk, cheese, nuts,
and dry beans are sources of Protein.
Made up of AMINO ACIDS
AMINO ACIDS
22 Amino Acids
Your body can make 13 of them.
The other 9 are called ESSENTIAL AMINO
ACIDS, and they must come from the food you
eat.
Complete Proteins come from animal sources
and contain all 9 essential amino acids.
Incomplete Proteins come from plant sources
and lack at least 1 essential amino acid.
VITAMINS
VITAMINS
Substances needed in small quantities
that help regulate body functions.

2 Groups of Vitamins
Water – soluble

Vitamin C & B
Fat – soluble

Vitamin A D E & K
VITAMINS
Water – soluble


Can NOT be stored in
the body
Must be included in
your diet
Fat – soluble

Can be stored in the
body until needed.
MINERALS
MINERALS
Elements needed in small
quantities for sturdy
bones and teeth, healthy
blood, and regulation of

SATURATED FATS
Fats found in meats
and dairy products
Eating to much
Saturated fat can
raise blood
cholesterol levels,
increasing the risk of
heart disease.
Solid @ room temp.
UNSATURATED FATS
Found mainly in
vegetable oils, such
as olive, corn, or
canola oil, nuts and
avocados
Fats that remain liquid
@ room temp.
WATER
Most common
nutrient
Makes up 60% of the
body
WATER
Carries nutrients
through body
Helps digestion
Removes waste from
body
Lubricates joints
Keeps body from
overheating
HEALTHY DIET SUMMARY




Balance of nutrients
Too much fat may lead to heart disease
Too little protein hinders growth
You need a variety of healthy foods to get all
the nutrients!
Calories
The number of calories people should eat each day
depends on several factors, including their






Age
Size
Height
Gender
Lifestyle
Overall general health.
A physically active 6ft 2in male, aged 22 years, requires
considerably more calories than a 5ft 2ins sedentary woman in her
70s.
Recommended Daily Calories
According to the National Health Service (NHS), UK, the average male adult
needs approximately 2,500 calories per day to keep his weight constant,
while the average adult female needs 2,000.
US authorities recommend 2,700 calories per day for men and 2,200 for
women.
It is interesting that in the UK, where people on average are taller than
Americans, the recommended daily intake of calories is lower. Rates of
overweight and obesity among both adults and children in the USA are
considerably higher than in the United Kingdom
Portion sizes
•
In industrialized nations and a growing number of emerging economies,
people are consuming many more calories than they used to. Portion sizes
in restaurants, both fast food ones as well as elegant places, are far greater
today.
•
The average cheeseburger in the USA 20 years ago had 333 calories,
compared to the ones today with over 600 calories
