Nutrient introduction

Nutrients are substances that need to be taken from the external environment in order to maintain all life activities and processes such as the body's reproduction, growth, and survival. Nutrients must be taken from food to meet the body's minimum requirement, namely survival. There are many types of nutrients from food. According to their chemical properties and physiological effects, nutrients can be divided into six categories, namely proteins, lipids, carbohydrates, minerals, vitamins and water. Nutrients can be divided into macro-nutrients and micro-nutrients according to the human body's requirements for various nutrients or the content in the body.
