Title: Nutrition
1Nutrition
High school students are increasingly in control
over the decisions that influence your health and
wellness, and the behaviors you learn throughout
your childhood and young adulthood will carry on
into your adult lives. Teens who are overweight
or obese are more likely to be overweight and
obese as adults, putting them at risk for chronic
diseases such as hypertension, heart disease, and
diabetes. While the decision to choose a
healthy lifestyle is ultimately up to the
individual, this unit will provide you with the
information you need to make knowledgeable and
responsible choices.
2The Problem
- About half of all American adults117 million
individualshave one or more preventable, chronic
diseases that are related to poor quality dietary
patterns and physical inactivity, including
cardiovascular disease, hypertension, type 2
diabetes and diet-related cancers. - More than two-thirds of adults and nearly
one-third of children and youth are overweight or
obese, further exacerbating poor health profiles
and increasing risks for chronic diseases. - On average, the U.S. diet is low in vegetables,
fruit, and whole grains, and high in sodium,
calories, saturated fat, refined grains, and
added sugars. Under consumption of the essential
nutrients vitamin D, calcium, potassium, and
fiber are public health concerns for the majority
of the U.S. population, and iron intake is of
concern among adolescents and premenopausal
females.

5Nutrients
- Nutrients are substances that the body needs to
regulate bodily functions, promote growth, repair
body tissues, and obtain energy.
66 NUTRIENTS!!!!
- Carbohydrates
- Fats
- Proteins
- Vitamins
- Minerals
- Water
7Energy Nutrients
- Why do we need energy?
- Your body needs energy for everything you do
running, playing an instrument, even sleeping. - You need energy to maintain your body temperature
and keep your heart beating - Energy nutrients provide calories
- Energy nutrients include carbohydrates, proteins
and fats in the form of calories. - Calorie unit for the amount of energy released
when nutrients are broken down
8Energy Nutrients Carbohydrates
- Two Types
- Simple Refined Grains
- Complex Whole Grains
9Simple CarbohydratesRefined Grains
- Refined grains have been milled, a process that
removes the bran and germ. - This is done to give grains a finer texture and
improve their shelf life, but it also removes
dietary fiber, iron, and many B vitamins. - Examples Sugars that naturally occur in
fruits, vegetables and milk, white flour,
de-germed cornmeal, white bread, and white rice - Added sugars to manufactured foods such as
cookies, candies, soft drinks
10Complex Carbohydrates Whole Grains
- Contain the entire grain kernel
- ? the bran, germ, and endosperm
- Complex carbohydrates take longer for your body
to metabolize than simple carbohydrates - Two Types Starches Fiber
- Starches found in plant foods, such as potatoes,
grains, brown rice, oatmeal, corn, and wheat
products
11Complex Carbohydrates
- Fiber a type of complex carbohydrate that cannot
be broken down by the body so it passes through
your body without being digested (25 mg per
day) - Benefits of a high fiber diet include

vegetables, fruits, nuts, beans and seeds
12Fats

cells, maintain body temperature, and protect
your nerves. - Two Types

- Important for cardiovascular health can help
fight heart disease - Found in plant products
- Monounsaturated Polyunsaturated fats (oils)
- Saturated Fats aka Bad Fat
- Too much can lead to cardiovascular disease
- Solid at room temperature
- Found in animal fats, lard, and dairy products
14Proteins
- Proteins most important function is their role in
the growth and repair of your bodys tissues - All foods made from meat, poultry, seafood, beans

Group. Beans and peas are also part of the
Vegetable Group. Milk is also part of the Dairy
group.
15Proteins

- There are 20 different amino acids 9 are
essential, meaning you must get them in your
diet, the other 11 your body can manufacture from
your diet - Complete Proteins contain all 9 essential amino
acids - Meats fish
- Incomplete Proteins Lacks 1 or more of the
essential amino acids - Plant sources, such as beans
16Vegetarian, Vegan Protein
- Someone who does not eat meat, poultry, fish,
eggs or dairy products - Foods that are a good source of protein
- Green peas, quinoa, nuts and nut butter, beans,
chickpeas, tempeh and tofu (soybeans), edamame,
leafy greens, hemp, chia seeds, seeds, seitan,
and non-dairy milk -
17- Milk is a good source of calcium, vitamin D, and
riboflavin. Dairy products CAN be good sources of
Proteins - Foods made from milk that have little to no
calcium, such as cream cheese, cream, and butter,
are not. Calcium-fortified soymilk (soy beverage)
is also part of the Dairy Group. - Try to choose milk group choices that are
- fat-free
- low-fat
18Lactose Intolerance
- the inability of adults to digest lactose, a
sugar found in milk, and to a lesser extent dairy
products, causing side effects. - Foods to avoid
- Milk, yogurt, cheese, calcium-fortified cereals
- How can they get calcium?
- Lactose-free milk, hard cheeses, dark leafy
greens, almonds
19Gluten Free Celiac Disease
- an autoimmune disorder of the small intestine
that occurs in genetically predisposed people of
all ages - Symptoms include pain and discomfort in the
digestive tract, chronic constipation
and diarrhea, failure to thrive (in
