Dietary guidelines

B1. Integrate USDA Dietary Guidelines in planning and preparing foods to meet nutrition and wellness needs.


Dietary guidelines

  • Introduced by the USDA in 1943.

  • Used to maintain nutritional standards during wartime rationing.

  • “Basic 7” quickly replaced by “Basic 4”.


Dietary guidelines

  • The Basic 7 was in place from 1943 – 1956.

  • After that, came the Basic 4.

  • The Basic 4 included:

    • Meats, poultry, fish, eggs, beans

    • Dairy products

    • Grains

    • Fruits and vegetables

  • The Basic 4 lasted from 1956 – 1992.


Dietary guidelines

  • This was the first food pyramid, introduced in 1992.

  • The USDA’s slogan for this time was, “Going beyond the ‘basic four food groups’ to help you put the Dietary Guidelines into action”.


Dietary guidelines

  • In 2005, the USDA released this updated food pyramid.

  • The pyramid was broken down into grains, vegetables, fruit, oils, milk, and meat and beans.

  • This pyramid also incorporated the importance of exercise.


Dietary guidelines

  • In June of 2011the USDA replaced the pyramid with the plate.

  • Many people were surprised by the presence of protein.

  • What foods are included in protein?


Nutritional needs

Nutritional needs

  • The foods we eat provide us with a variety of nutrients.

  • Nutrients are chemical substances from food that the body needs to live.

  • Nutrition is the study of how the body uses the nutrients in the foods that are eaten.

  • If you do not eat the foods your body needs, you may suffer from malnutrition.

  • Malnutrition is a lack of the right proportions of nutrients over an extended period of time.


Nutritional needs1

Nutritional needs

  • An inadequate diet can cause malnutrition.

  • Malnutrition can also be caused by the body’s inability to use nutrients from foods.

  • Energy, growth, repair, and the regulation of various body processes can all be impaired.


Nutritional needs2

Nutritional needs

  • A person’s body weight is not a sign of their nutritional status.

  • A person who is malnourished could be overweight, underweight, or even a normal/healthy weight.

  • Eating ENOUGH food doesn’t mean you are eating the foods you NEED.

  • The AMOUNT of food eaten is not as important as the RIGHT VARIETY of foods.


Nutritional needs3

NUTRITIONAL NEEDS

  • Some effects of malnutrition may be long lasting.

    • The foods a teen girl eats today may affect her pregnancy in later years.

    • The foods a pregnant woman eats may affect her unborn child’s development.

    • The foods a child eats may affect his or her growth and resistance to disease.

  • Each person’s health and life span may be affected by their food choices.


The nutrients

The nutrients

  • Several nutrients may be described as nonessential nutrients. Some of these nutrients are substances the body can make.

  • Therefore, you do not need to get them from the foods you eat.

  • Cholesterol is an example of this type of nutrient.

  • Other nonessential nutrients do not meet the true definition of nutrients because they are not required to sustain life. However, they are substances from foods that have an impact on health.


The nutrients1

The nutrients

  • The essential nutrients are substances the body cannot make – at least not in a quantity needed to sustain life.

  • These nutrients must be supplied by the foods you eat.

  • There are over 50 essential nutrients that we need for good health.

  • Some supply energy for the body.

  • All of them help build and maintain cells and tissues. They also regulate bodily processes such as breathing.

  • No single food supplies all the nutrients the body needs to function.


The nutrients2

The nutrients

  • Failure to get enough of needed nutrients may result in a deficiency disease.

  • A deficiency disease can be caused by 2 things:

    • Not getting enough of a particular nutrient

    • Not getting a good mix of different nutrients

  • Groups of people more vulnerable to nutrient deficiencies: pregnant women, nursing mothers, infants, and children up to the age of 2.

  • Getting an excess of some nutrients can result in toxicity.

  • Toxicity can be just as harmful as a deficiency.


Dietary supplements

Dietary supplements

  • Some people have trouble meeting all their nutritional needs from food alone.

  • Dietary supplements can help make up for any shortages in their diet.

  • Dietary supplements are purified nutrient or non-nutrient substances that are manufactured or come from natural sources.


Dietary supplements1

Dietary supplements

  • Not all dietary supplements provide nutrients. Some provide non-nutrient substances like herbs and some antioxidants.

  • Antioxidant: substance that prevents or slows damage caused by chemical reactions in the body.

  • Antioxidants also break down certain materials in the body.

  • Antioxidants may lower the risk of heart disease and cancer.

  • Antioxidants also might help improve the function of the immune system.


The nutrients3

The nutrients

  • Fortified foods: foods that have nutrients added in amounts that are greater than what they would naturally be

  • Example: orange juice naturally contains a small amount of calcium. Calcium fortified orange juice serves as an excellent source!
