Nutrition Policies
• Need for policies– Centers are doing a poor job of providing
nutrition• Inadequate calories, calcium, iron, folate,
vitamin E, zinc• Too much fat • 90% of CACFP centers studies fell short of
meeting needs• Low degree of staff knowledge has a direct
effect on nutrition

Nutrition Policies (continued)
– 13 million children in child care get a significant part of their weekday nutrition from there
• For children in care all day, 2 of 3 meals are eaten in care
– Parents should consider nutritional program of a center when choosing child care

Nutrition Policies (continued)
• Major goals for nutrition policies– Maximize nutritional status– Minimize nutritional risk– Use nutritional education as a tool– Recognize importance of nutritional
guidelines– Practice cultural competence– Develop partnerships with families to
provide a caring community

Understanding Nutritional Guidelines
• Build a healthy base– Aim for fitness
• Aim for a healthy weight • Be physically active for 60 minutes per day
• Dietary Guidelines for Americans
© 2007 by Thomson Delmar Learning
Understanding Nutritional Guidelines (continued)
• Build a healthy base– Meet recommended intakes within energy needs by
adopting a balanced eating pattern, such as the USDA MyPyramid Food Guidance System
– Consume a variety of nutrient-dense foods and beverages within and among the basic food groups while choosing foods that limit the intake of saturated and trans fats, cholesterol, salt, and added sugars
– Consume a sufficient amount of fruits and vegetables while staying within energy needs
– Children 2 to 8 years should consume 2 cups per day of fat-free or low-fat milk or equivalent milk products
– Keep foods safe to eat
© 2007 by Thomson Delmar Learning
Understanding Nutritional Guidelines (continued)
• Dietary guidelines for Americans– Choose sensibly– Choose a variety of fruits and vegetables each day. In
particular, select from all five vegetable subgroups (dark green, orange, legumes, starchy vegetables, and other vegetables) several times a week
– Consume whole-grain products often; at least half the grains should be whole grains
– Keep total fat intake between 20 to 35 percent of calories, with most fats coming from sources of polyunsaturated and monounsaturated fatty acids, such as fish, nuts, and vegetable oils
– When selecting sources of protein, make choices that are lean, low-fat, or fat-free
– Choose fiber-rich fruits, vegetables, and whole grains often

MyPyramid Food Guidance System
• Emphasizes fruits, vegetables, whole grains, and fat-free or low-fat milk and milk products
• It focuses on lower-fat or lean meats, poultry, fish and includes beans, eggs, and nuts as acceptable sources of protein
• Recommendations of the system are inter-related and head the individual toward an increased intake of dietary fiber, vitamins and minerals, and other essential nutrients
© 2007 by Thomson Delmar Learning
MyPyramid Food Guidance System (continued)
• The system is divided into two levels:– Individualized daily food intake
recommendations– Information to help individuals make better
food choices
• Variety, proportionality, moderation, and activity are the focus
© 2007 by Thomson Delmar Learning
MyPyramid Food Guidance System (continued)
• Focus is on – grains – vegetables – fruits – milk and milk products– meat and beans
• minor focus on oils• no focus on cutting down on sugars
© 2007 by Thomson Delmar Learning
MyPyramid Food Guidance System (continued)
© 2007 by Thomson Delmar Learning
• U.S. Daily Reference Intake (DRI)– Food label (see next slide [Figure 6-8])
• Calories, fat, cholesterol, carbohydrates, protein, vitamin A, vitamin B, vitamin C, calcium, and iron are listed
• Trans fats added in 2006
• Healthy People 2010
• Child and adult care food program

Reality Check—How Is America Eating: Do We Fulfill Our Nutritional
Needs?• We are eating a lot more fat today than
100 years ago – Cholesterol levels of foods lower– Less from animal sources– Consumption of meat up– Consumption of beef down– Eating more fat in snacks, and the like
© 2007 by Thomson Delmar Learning
Reality Check—How Is America Eating: Do We Fulfill Our Nutritional
Needs? (continued)
• We are eating more grains than we have for a number of years
• But we are still eating less grains than 100 years ago
• The grain items we are eating have highly processed flours, rice, and pastas or have added sugar
© 2007 by Thomson Delmar Learning
Reality Check—How Is America Eating: Do We Fulfill Our Nutritional
Needs? (continued)• Bran and germ have been removed from
processed foods • Healthy Eating Index found that the mean
score was about 64%, which means 36% of us are not meeting our dietary needs
• Quality of children’s diets was only 9% poor, while 72% of diets were needing improvement, but 19% of children’s diets were good

Basic Macronutrients
• Energy nutrients provide calories• fats—9 grams• proteins and carbohydrates—4 grams
– include• carbohydrates• fats• proteins
© 2007 by Thomson Delmar Learning
Basic Macronutrients (continued)
• Macronutrients are needed – to maintain life– for growth– to regulate the body – to perform voluntary activities
© 2007 by Thomson Delmar Learning
Basic Macronutrients (continued)
• Carbohydrates– First source of energy for the body– Major source of energy for central nervous
system– Provide glucose to liver to store for energy– Found in Level One and Level Two foods– Diet should consist of 58% carbohydrates– Too little causes body to use up fat and
protein
© 2007 by Thomson Delmar Learning
Basic Macronutrients (continued)
• Fats– Second source of energy– Supplies essential fatty acids for child’s
growth– Cushions organs, maintains body
temperature, promotes healthy skin, helps carry fat-soluble vitamins and regulates cholesterol metabolism
– Diet should consist of 25% to 35% fats
© 2007 by Thomson Delmar Learning
Basic Macronutrients (continued)
• Types of fats– Saturated raises cholesterol found in animal fats– Monounsaturated is neutral found in olives, peanuts, nuts,
and avocados– Polyunsaturated lowers cholesterol found in plants and plant
oils– RDA recommends 10% from each category
• Adequate fat is necessary • Trans fats
– occur when vegetable oils are saturated as a result of the heat and hydrogenation in order to process these oils into margarine or shortening
– sources of trans fats • baked goods• snack foods• also found in some animal fat
© 2007 by Thomson Delmar Learning
Basic Macronutrients (continued)
• Protein– third source of energy– major building block in our bodies, found in
every cell– build new cells, aids in repairing damaged
tissue, forms enzymes for digestion, and provides hormones and antibodies that help resist infection
© 2007 by Thomson Delmar Learning
Basic Macronutrients (continued)
• Protein (continued)
– Made of amino acids• 9 are essential• Complete proteins have all 9• Complete proteins come from animal sources• Incomplete proteins have some but not all 9
essential amino acids• Foods must be combined properly to provide
complete protein
