Choosing a Healthy Diet

To be healthy, you need to eat a variety of foods. Using MyPlate is recommended because it provides the amount and variety of food you need each day to stay healthy. Consuming a variety of healthy foods ensures that you obtain all the nutrients you need—calories, protein, fat, carbohydrates, vitamins, minerals, fiber and water. The latest Dietary Guidelines for Americans (2010), was released on Jan. 31, 2011 and emphasizes three major goals for American diets:

  • Balance calories with physical activity to manage weight
  • Consume more of certain foods and nutrients such as fruits, vegetables, whole grains, fat-free and low-fat dairy products, and seafood
  • Consume fewer foods with sodium (salt), saturated fats, trans fats, cholesterol, added sugars, and refined grains

Eating right and being physically active are the keys to a healthy lifestyle. By maintaining healthy habits, you may reduce the risk of chronic diseases such as heart disease, diabetes, osteoporosis, cancer and increase your chances of a longer life. A healthy meal plan emphasizes:

  • Fruits, vegetables, whole grains, skim or low-fat milk and milk products.
  • Lean meats, poultry, fish, eggs, beans and nuts.
  • Low in saturated fats, trans fats, cholesterol, sodium (salt) and sugar.

  • Calories

    Our body uses the calories from food to provide the energy needed for basic body functions and physical activity. Excess calories are stored as body fat. The balance between the calories consumed and exercise to use the calories is important to maintain normal body weight.

  • Protein

    Our body tissues and muscles are composed of protein. Metabolic stress from acute illness, infection, surgery, bone fractures and some chronic diseases can increase the protein needs. The best sources of protein are milk, cheese, meat, poultry, fish, nuts, dried beans and peas.

  • Fat

    Fat is an essential nutrient because it promotes the absorption of vitamin A, D, E, K and provides essential fatty acids that cannot be manufactured by the body. The type and total amount of fat in your diet is important to prevent cardiovascular disease. The American Heart Association recommends reducing the total fat, saturated fat, trans fats and cholesterol in your diet.

    • Total Fat - Fat is a concentrated source of calories because it provides 9 calories per gram. In comparison, protein and carbohydrates provide only 4 calories per gram. To maintain normal body weight, you should include a fat source with each meal; however, total fat should not exceed 20 – 30% of total calories.
    • Saturated Fat - Diets high in saturated fat tend to increase the blood cholesterol. Saturated fats are usually solid at room temperature and are provided mainly from animal sources (butter, lard, bacon, poultry skin) and plant sources (palm, coconut and hydrogenated vegetable oils in shortening and margarines). Monounsaturated fats (canola, olive, peanut) and polyunsaturated fats (corn, safflower, soy, sunflower) may be substituted to lower blood cholesterol.
    • Cholesterol - High blood cholesterol levels have been linked to heart disease. Many foods from animal sources are high in cholesterol, such as heavily marbled meats, poultry skin, sausage, bacon, processed meats, whole milk and whole milk products, and egg yolk. To maintain a healthy-healthy diet, cholesterol intake should not exceed 200 mg per day. The American Heart Association recommends that total blood cholesterol should be maintained less than 200 mg/dl.
  • Carbohydrates

    Carbohydrates are the major source of energy for the body. Complex carbohydrates - such as whole grain bread, cereals, pastas, rice, vegetables and fruits - are excellent sources of vitamins, minerals and fiber. Simple carbohydrates - such as sugar, candy, jelly, cakes, cookies and soft drinks - should be limited in the diet because they add “empty” calories and provide very little nutritional value. Also, sticky, sweet foods promote tooth decay.

  • Vitamins

    Eating a variety of foods from MyPlate will supply the minimum daily requirements of vitamins. Be sure to include one serving of fruit high in Vitamin C daily (i.e. orange, grapefruit, cantaloupe). Also, include dark green leafy and dark yellow/orange vegetables or fruits in your daily meal plan to obtain the minimum requirement for Vitamin A.

  • Minerals

    Our mineral needs remain about the same throughout life with the exception of calcium and iron. Adequate intake of calcium is important throughout life to build strong bones and teeth, and prevent bone loss called osteoporosis. Milk, cheese, yogurt, dark green leafy vegetables, salmon, sardines, soybeans and tofu are excellent sources of calcium. Iron is necessary for building red blood cells to maintain normal hemoglobin levels. Rich sources of iron include liver, egg yolk, dark green leafy vegetables, whole grain breads and cereals.

  • Fiber

    Complex carbohydrates such as whole grain breads and cereals, vegetables and fruits contribute dietary fiber necessary for lowering cholesterol and reducing the risk of diverticulosis and colon cancer. Twenty to 35 grams of fiber a day is recommended to maintain normal bowel function and other health benefits.

  • Water

    Adequate water intake is essential to maintain proper hydration required for body functions and exercise. Eight glasses of water per day is recommended in addition to other fluids.
