Summarize the nutritional requirements for dietary carbohydrates, lipids, and proteins, and trace the fate of glucose, lipids, and amino acids after their absorption.

Summary Introduction

To summarize: The nutritional requirement for dietary carbohydrate, lipids, and proteins, and trace the fate of glucose, lipids, and amino acids after their absorption.

Introduction: Nutrient is an essential requirement of the body to perform normal physiological functioning by providing energy, regulating cell metabolism and by promoting growth and development. Nutrients can be classified into two types: macronutrients such as protein, fat and carbohydrate, which is required by the body in large amount and the other is micronutrients such as minerals and vitamins which are required in trace amounts.

Explanation of Solution

The nutritional requirement for dietary carbohydrate, lipids, and proteins are as follows:

Dietary carbohydrates

Carbohydrates are the major source of energy which is mostly consumed in complex form such as starches. Starches are the complex carbohydrates. They are the main storage carbohydrate in the plants. They are mainly composed of two polysaccharides - amylose and amylopectin. The foods made from starchy vegetables, flours or grains are highly rich in starch. The digestive enzyme known as amylase are necessary to degrade the dietary starches for the normal absorption.

Dietary proteins

Proteins are one of the dietary components and essential nutrient for the human body. Proteins are mediators of several important processes such as growth, repair, food break down, and several other processes that take place in the body. There are some amino acids that our body could not produce are called as essential amino acids. Essential amino acids must be supplied through diet. Out of the 20 amino acids, there are 9 essential amino acids obtained from diet. The diet should include complete protein, that is, adequate portion of the entire 9 amino acids should be included. All essential amino acids are not present in one food.

Dietary lipids/fats

Dietary fat is the amount of fat that we consume through our food. Fats maintain the core body temperature and provide energy. So, it is an important part of our diet. From the total daily calories included in the healthier diet, about 20-30 percentage of the fat should come from the diet...
