"Nutrition in Food" Food PPT

Part 1: What nutrients do foods contain?

What nutrients do our bodies need for growth and development? What nutrients can we get from a wide variety of foods?

The life activities of the human body require the support of a variety of nutrients.

Food is very rich in nutrients, usually divided into: protein, sugar, fat, vitamins and minerals, and water.

Protein is the main component of human muscles, organs, hair, nails and blood. It is used for body growth and development, aging tissue renewal, damaged tissue repair, and various physiological functions.

The main function of sugar is to supply energy required for life activities. Generally speaking, more than 70% of the energy required by the human body is provided by the oxidative decomposition of sugars. Sugar often accounts for more than 80% of the food we eat every day, mainly starch.

Vitamins, also known as vitamins, are an indispensable nutrient for the human body. Vitamins are a type of nutrients necessary for the human body to maintain normal metabolism and functions. The human body's daily requirement for vitamins is very small, but if it is lacking, it can cause a special type of disease called "vitamin deficiency."
