Recommended Dietary Allowance is a Guide in Determining Nutrients a Day

Human beings require food to grow, reproduce, and maintain good health. Without food, our bodies could not stay warm, build or repair tissue, or maintain a heartbeat. Eating the right foods can help us avoid certain diseases or recover faster when illness occurs. These and other important functions are fuelled by chemical substances in our food called nutrients. Nutrients are classified as carbohydrates, proteins, fats, vitamins, minerals, and water.
Good health or “wellness” is not a matter of chance. Good health is a product of good nutrition which is the result of an adequate supply of essential nutrients in the body. The food we eat everyday supply the essential nutrients to our body. These are carbohydrates, fats, proteins, vitamins, and minerals. A balanced diet consists of a variety of foods of the right kind, in the right amount and proportion .Hence, RDA serves as a guide to the right kind and amount of foods we need for growth and development. Proper nutrition is required to be in good health. Optimum nutrition is only possible if one eats adequate food, practices good eating habits, and develops good relationships with the Supreme Being and other people. Being happy and peace loving contribute to your good health.
Optimum nutrition results to good health which makes a person productive. If all members of the family are productive, they will contribute to the development and progress of our country.
II. Statement of the Problem
❖ Is RDA (Recommended Dietary Allowance), evaluate whether your family is eating the right kind and amount of food?
❖ Is RDA (Recommended Dietary Allowance) suggests to correct deficiencies?

To determine healthful nutrition standards, the Food and Nutrition Board of the National Academy of Sciences (NAS), a nonprofit, scholarly society that advises the United States government, periodically assembles committees of national experts to update and assess nutrition guidelines. The NAS first published its Recommended Dietary Allowances (RDAs) in 1941. An RDA reflects the amount of a nutrient in the diet that should decrease the risk of chronic disease for most healthy individuals. The NAS originally developed the RDAs to ensure that World War II soldiers stationed around the world received enough of the right kinds of foods to maintain their health. The NAS periodically has updated the RDAs to reflect new knowledge of nutrient needs.
In the late 1990s the NAS decided that the RDAs, originally developed to prevent nutrient deficiencies, needed to serve instead as a guide for optimizing health. Consequently, the NAS created Dietary Reference Intakes (DRIs), which incorporate the RDAs and a variety of new dietary guidelines. As part of this change, the NAS replaced some RDAs with another measure, called Adequate Intake (AI). Although the AI recommendations are often the same as those in the original RDA, use of this term reflects that there is not enough scientific evidence to set a standard for the nutrient. Calcium, which has an AI of 1,000 to 1,300 mg per day, is not an RDA because scientists do not yet know how much calcium is needed to prevent osteoporosis.
To simplify the complex standards established by the NAS, the United States Department of Agriculture (USDA) created the Food Guide Pyramid, a visual display of the relative importance to health of six food groups. | | | |
