Chapter 33 - Part 1 - Recording - Nutrients PDF

Summary

This document discusses different types of dietary deficiencies, including malnutrition and deficiencies in essential nutrients, such as vitamin A and amino acids. It also describes how animals obtain nutrients. The document explains the concept of food processing that includes ingestion, digestion, absorption, and elimination and highlights the importance of an adequate diet.

Minerals (무기질) • Minerals (무기질) are simple inorganic nutrients, usually required in small amounts (무기질은 일반적으로 소량만 필요한 단순 무기질 영양소임) • Ingesting large amounts of some minerals can impair health (일부 미네랄을 다량 섭취하면 건강이 나빠질 수 있음 – 칼슘과다 섭취 -> 결석증)...

Minerals (무기질) • Minerals (무기질) are simple inorganic nutrients, usually required in small amounts (무기질은 일반적으로 소량만 필요한 단순 무기질 영양소임) • Ingesting large amounts of some minerals can impair health (일부 미네랄을 다량 섭취하면 건강이 나빠질 수 있음 – 칼슘과다 섭취 -> 결석증) Dietary Deficiencies (식이결함) • Malnutrition (영양실조) results from the long-term absence from the diet of one or more essential nutrients (영양 실조는 하나 이상의 필수 영양소를 장기간 섭취하지 않아서 발생함) Copyright © 2021 Pearson Education Ltd. All Rights Reserved Deficiencies in Essential Nutrients (영양실조) • Deficiencies in essential nutrients can cause deformities, disease, and death (필수 영양소 결핍은 기형, 질병, 사망을 유발할 수 있다) • Animals may consume salt or other minerals to obtain missing nutrients (동물은 부족한 영양소를 얻기 위해 소금이나 기타 미네랄을 섭취할 수 있다) Figure 33.3 Obtaining Essential Nutrients from an Unusual Source (일반적이지 않은 방식으로 필수영양소를 획득하는 동물) Copyright © 2021 Pearson Education Ltd. All Rights Reserved Deficiencies in Essential Nutrients (영양실조) • A diet with insufficient amounts of one or more amino acids is the most common type of malnutrition among humans (하나 이상의 아미노산이 불충분 한 식단은 인간에게 가장 흔한 영양 실조 유형임) • Individuals subsisting on simple rice diets are often deficient in vitamin A (단순 쌀 식단으로만 생활하는 사람들은 비타민 A가 부족한 경우가 많다) • To overcome this, scientists have engineered a strain of rice that synthesizes betacarotene, which is converted to vitamin A in the body (이를 극복하기 위해 과학자들은 체내에서 비타민 A로 전환되는 베타 카로틴을 합성하는 쌀 품종을 발함) Copyright © 2021 Pearson Education Ltd.
