NUTRITION:A Healthy Diet
Ms. MaiLawndale High School
A Healthy DietIf you lived to be 100 years old, you will have eaten about 110,000 meals
That is about 1,100 meals per year, not including snacks
Eating becomes pretty automatic, but good nutrition is not
Good NutritionGood nutrition involves selecting a variety of foods, following good health guidelines, and eating only what your age and activity levels require
What you eat each day should provide enough of all the nutrients that are needed for your growth and activities
Choosing FoodIn many countries, people only eat food that is available to them without choice
Today, there are many choices
It is not always easy to choose, but food guidelines can helpIn 1992, the USDA issued the Food Guide Pyramid to help provide guidelines for making food choices by grouping foods and recommending a number of serving from each group
Food Guide Pyramid
Examples of Healthy FoodFOOD GROUP 1 SERVING SIZE
Bread, Cereal, Rice, and Pasta
1 slice of bread½ cup of cooked rice or pasta
Vegetable 1 cup of raw vegetables½ cup of cooked vegetables
Fruit 1 apple, banana, orange½ cup chopped, or canned fruit
Meat, Poultry, Fish, Dry Beans, Eggs, Nuts
2-3 oz. cooked meat, fish, poultry1 egg or ½ cup of cooked beans
Milk, Yogurt, Cheese 1 cup of milk or yogurt2 oz. cheese
Food GroupsThe pyramid is made up of 6 section, but nutritious foods are divided into only 5 of the 6 groups arranged according to the number of serving needed each day
No one group is more important than another in maintaining health
Fats, oils, and sweets are placed at the tip of the pyramid to emphasize how little you need of them
Guidelines for Balanced Diet
1. Eat a variety of foods2. Maintain a healthy weight3. Choose a diet low in fat and
cholesterol, and high in vegetables, fruits, and grains
4. Eat sugar and salt in moderation
Making Wise Food ChoicesWhenever you skip a meal, you end up feeling lightheaded, shaky, anxious, and crankyThese symptoms tell you that your body has not been given enough fuelAlthough the human body is an incredible repairing machine, it needs proper care to function at its peak
An Important MealBreakfast is the most missed meal, but one of the most important meals
At breakfast, your body has gone 12 – 14 hours without food
Breakfast can provide you with necessary nutrients and energy to be used throughout the day, reduce irritability, and decrease nervousness
BreakfastA well-balanced breakfast might include a glass of orange juice, a bowl of cereal or 2 slices of toast, and a glass of milk
Any breakfast is acceptable as long as it supply the essential nutrientsIf you miss essential nutrients at one meal, you need to make them up with a well-chosen snack, or at your next meal
NON-NUTRITIOUS SUBSTSANCESCaffeine – this stimulant is a drug that speeds up the body’s activity and can cause nervousness, edginess, irritability, hyperactivity (coffee, tea, chocolate, soda)
Artificial Sweeteners – developed for people with diabetes, but does not result in weight lossAlcohol – contains empty Calories and can prevent the body from burning Calories that should be burnedFat Substitutes – contains no cholesterol or fat, but may have side effects over long periods of time (frozen desserts and other non-heated food products)
SnackingSnacks can play an important role in your daily diet, especially in teen years
Select nutrient-dense foods that are high in complex carbohydrates, vitamins, and minerals, and low in fat, sugar, and saltSome good snack choices are whole-grain breads, cereals, low-fat yogurt, fruits, raw vegetableSome poor snack choices are chocolate, potato chips, pastries, and sodas
Vegetarian Diets
For a many reasons, some people choose to limit certain foods from their diets
Vegetarians are people who choose to eat no animal foods
Types of Vegetarians
Lacto-Ovo Vegetarian – eat eggs, milk, and milk products, but no read meat, fish, and poultry
Vegan – eat no animal food of any kindSemi-Vegetarians – eat fish, poultry, eggs, and dairy products, but no red meat
Vegetarian’s DietA vegetarian’s diet is healthy as long as it contains all the essential nutrients
Vegetarians need complementary proteins (mixture of incomplete protein), and enough Calories to meet all energy needs
Sometime, vegetarians also take supplements to get enough vitamins, but overall they have a diet lower in fat
Fast FoodsFast foods are a part of modern society
Many fast food meals provide adequate protein, but often contain a lot of fat and sodium and are low in vitamins and mineralsIt is possible to eat a balanced meal at a fast food restaurant as long as you are making wise decisions that cover all essential nutrients
