Too few nutrients

Diet & NutritionFCS-FNW-1. Students will discuss basic nutrient requirements and their use in dietary planning.

Too few nutrients
Too Few Nutrients

Malnutrition is a serious health problem caused by a continuing lack of nutrients, or the body’s poor absorption or use of nutrients

Often is a result of food shortages or poverty

BUT…even people who get enough to eat can develop malnutrition if they make poor food choices

How can the community help with malnutrition
How Can the Community Help with Malnutrition?

Food Stamps

Government program that helps people with limited income buy food

Women, Infants, and Children (WIC)

Government program that gives food assistance and nutrition education to pregnant and nursing women, infants, and preschool children who are in need

Home Delivered Meals

Meals are delivered to disabled or elderly

Food Banks

Program that gets donations from community to distribute to people in need

Community Kitchens

Low cost or no cost meals are provided to people

Nutritious diets
Nutritious Diets

  • There is no “perfect” diet because everyone is built different and has different nutrient needs.

  • However, there are a few guidelines to remember when creating a diet.

    • Remember, the word “diet” does not mean you are “losing weight”. It is simply the foods you eat and the liquids you drink.

Nutrients through the lifespan
Nutrients Through the Lifespan

Each stage of the lifespan needs certain nutrients to help the body properly develop.

Infancy, childhood and the teen years are the most crucial years for proper intake of nutrients. The “grow” nutrient is most important.

Pregnant and lactating women usually need an increased intake of nutrients due to the changes in their bodies.

Adults and the elderly tend to decrease their intake of nutrients because their bodies are not growing. Instead, adults and the elderly have a slower metabolism and turn more nutrients into fat.

Nutritious diets1
Nutritious Diets

  • Adequate

    • A diet that is sufficient in all needed nutrients

  • Balanced

    • A diet that offers correct servings from each of the food groups

  • Moderation

    • Eating each of the food groups in proper amounts

Nutritious diets2
Nutritious Diets

  • Portion Distortion

    • Serving food portions that are well beyond the recommended serving portion size (ex: Super Size)

  • Varied

    • A diet with a variety from each food group (ex: eating grapes, strawberries and bananas…NOT just fruit – also from vegetable group)

  • Nutrient Dense

    • Choosing foods that offer the most nutrients for the amount of calories they provide

Weekly diet worksheet
Weekly Diet Worksheet

  • Your task is to develop a weekly diet for a teenager (either male or female) that follows the components of a nutritious diet.

  • Later, after we discuss Dietary Reference Intakes, you will revisit your weekly diet and make any necessary changes.

    • Use a pencil so changes can easily be made.

    • Keep your diet realistic: consider foods that a teenager would want to eat, while remembering to present them in a healthy way.

Dietary reference intakes
Dietary Reference Intakes

Everyone needs the same nutrients

How much you need depends on:



Activity rate



Dietary reference intakes1
Dietary Reference Intakes

As a teen, your nutrient needs are higher now than they will be at any other time in your life.

Dietary Reference Intake (DRI’s) standards, which give information on how much of each nutrient one needs to intake. They are part of the Recommended Daily Allowances (RDA’s).

Remember, these requirements are researched and are also based on a daily diet.

The USDA has a web link with a complete list of DRI’s listed at:

Dietary reference intakes worksheet
Dietary Reference Intakes Worksheet

  • You will make a DRI refrigerator magnet, specific for you and your family, as a reminder for daily meals

    • Using the website listed below, customize the chart your teacher will give you.

      • Be certain to write clearly, in pen

        • You may cut the chart according to how many family members you have

        • It is suggested that you shade each family member’s row a different color using a colored pencil so it is easier for them to read.

      • The chart will be laminated and your teacher will give you magnets to put on the back.

Nutrient deficiencies
Nutrient Deficiencies

  • A Nutrient Deficiency is a shortage of a nutrient

    • If you do not get enough of a nutrient a deficiency will result and poor health or lack of energy may be the result

      • The effects of some deficiencies take a long time to show

        • Example: Not enough calcium in the teen years may not show until the elderly years (less dense bones)

Vitamin c scurvy

  • Scurvy can cause bleeding gums, “cork screw” hairs or bleeding follicles, and bleeding fingernails

  • Scurvy was first discovered in sailors…Do you know why?

Protein kwashiorkor
PROTEIN: Kwashiorkor

  • Kwashiorkor is characterized by a protruding abdomen due to lack of proteins

  • This deficiency is usually seen in third world countries

Iodine goiter
IODINE: Goiter

  • Lack of iodine can cause your thyroid to enlarge and then produce a goiter

  • These can be painful and uncomfortable


Iron anemia
IRON: Anemia

  • Low red blood cell count

  • Leads to poor transport of oxygen through the blood

Vitamin a night blindness
VITAMIN A: Night Blindness

  • Unable to see properly at night

  • Things are viewed darker than they really are

  • The middle of this picture would be what someone with night blindness would see

Vitamin d rickets
VITAMIN D: Rickets

  • Rickets is characterized by bowed legs and bones

  • This is usually found in third world countries

Calcium osteoporosis
CALCIUM: Osteoporosis

  • Lack of calcium will cause bones to become brittle and less dense than normal bones

Getting too many nutrients
Getting Too Many Nutrients

Poor nutrition can also result from getting too many nutrients

Example: too much fat can lead to heart disease and other problems

Excess amounts of vitamins and minerals can cause serious harm to your body

Example: too much vitamin A can damage your liver

Taking too many vitamin and mineral supplements can cause this
