Title: Nutrients
1Nutrients
2Nutrients
- Major nutrients in food are classified into six
groups. They work in partnership for health. - Carbohydrates
- Fats
- Proteins
- Vitamins
- Minerals
- Water
3Macronutrients
- Nutrients we ingest in large quantities on a
regular basis. These includes - Carbohydrates
- Fats
- Proteins
- and water.
4CarbohydratesFunctions in the body
- Your bodys main source of energy or calories.
Helps your body use fats efficiently. - Classified in two groups
- complex carbohydrates or
- simple sugars.
5From Complex to Simple
- All carbohydrates sugars and starches break
down to simple sugars during digestion. Simple
sugars are glucose, galactose and fructose. - Glucose is the main form of carbohydrate used for
energy.
6Energy Storage
- The body doesnt burn all glucose at the same
time. Some gets stored in muscles and liver as
glycogen. Some glucose also may be converted to
body fat (if you consume more calories than your
body needs) - 1 gram of carbohydrate 4 calories
7Fiber Your bodys broom!!!
- Not a nutrient because it cannot be absorbed, but
it is very important. - It bulks up the contents of intestines.
- Fiber (a form of complex carbohydrate) aids in
digestion and offers protection from diseases.
8Good sources of carbs
- High-fiber foods legumes, whole-wheat bread,
bran, many cereals, strawberries, Brussels
sprouts, most fruits and vegetables, popcorn,
grains, nuts, seeds.
9Fiber
- We need about 25 grams per day.
- Most Americans get about 14 grams per day.
10- Too little
- Poor energy
- Tired
- Constipation
- Too Much
- Overweight problems and related diseases
11Fats
- Supply energy, but also have other functions
- Transport nutrients
- Support growth
- Part of many body cells
12Fats
- Fats supply 9 calories per gram.
- Extra fat in the diet is stored as adipose
tissue. - Fats give a smooth creamy texture to foods.
- Fats make you feel full.
13Types of Fat
- 1) UNSATURATED
- Monounsaturated liquid at room temperature.
Canola, nut, and olive oils are high in this
fatty acid. - Polyunsaturated liquid or soft at room
temperature. Corn, safflower, soybean and
sunflower oils. Fats in seafood are mainly
polyunsaturated.
14Types of Fat
- 2)Saturated firm at room temperature and are
from animal foods and coconut, palm and palm
kernel oils. - 3)Trans fatty acids formed during the process of
hydrogenation in which unsaturated fats are made
saturated. Found naturally in some foods. Extends
shelf life of products.
15Fats
- Most all foods contain fat in varying amounts.
Some are very high in fat others have just trace
amounts. - Be sure to check food label for fat content.
- Limit total fat intake to no more than 20 to 35
of calories and saturated fat to no more than 10
of calories.
16Sources of fats
- Saturated fat All animal foods Bacon etc.
- Unsaturated fats Fish, vegetable oils, poultry,
and soft and semisolid margarines. Oil from
coconut, olive and palm - Trans fat margarine, shortening, fried foods,
baked foods, salad dressing, cookies in tons of
food because it has a longer shelf life
17- Too little
- Dermatitis or skin inflammation caused by a lack
of amino acids - Too much
- Overweight problems and related diseases
18Protein
- Supply amino acids that are building blocks of
maintaining and repairing body tissue. - Help make antibodies to fight disease
- The body makes nonessential amino acids others
are essential in food. - Proteins provide energy when carbohydrates and
fat are in short supply.
19Protein Foods Sources
- Lean meat, poultry, fish, eggs, dry beans, tofu,
nuts, peanut butter, dairy foods
20- Too little
- Poor vitality muscle tone
- Increase chance of infections diseases
- Slow recovery from illness, injury, or surgery
- Extreme deficiency in children stunted growth,
low resistance to disease, mental retardation - Too much
- Waste of money since excess stored as fat and can
never be used for building and repairing cells
21Water
- Regulates body processes
- Carries nutrients and other body chemicals
- Carries waste products away
- Regulates body temperature
- Makes up 45 75 of body weight
22Water
- To keep your body functioning normally and to
avoid dehydration, your body needs an ongoing
water supply. - The average adult loses about 2 ½ quarts of water
daily more in hot weather. - Total Fluid Intake Daily
- Males (19 Over) 3.7 liters (125 ounces)
- Females (19 Over) 2.7 liters (91 ounces)
23Water
- Thirst signals the need for water, but it isnt a
foolproof mechanism, especially for the elderly,
children or during hot weather, illness or
exercise.
24To increase water supply
- Take water breaks during the day.
- Drink water with meals.
- Alternate sparkling water for soft drinks.
- Carry water with you.
- Drink before, during, and after exercise.
25Micronutrients
- The name given to vitamins and minerals because
your body needs them in small amounts. - Micronutrients are vital to your body's ability
to process the macronutrients
26Minerals

absorbed by plants and animals for proper
nutrition. - Minerals are the main component of teeth and
