This book is particularly beneficial for students pursuing undergraduate degrees in Food Technology, Food Science and Technology, Food and Nutrition, and other related fields, particularly those focusing on biochemistry and/or human nutrition. The book is divided into two main sections: Biochemistry and Human Nutrition. The first section is comprised of eight chapters covering the metabolism of macronutrients such as carbohydrates, proteins, and lipids, as well as the basics of vitamins, enzymes, hormones, and nucleic acids. The second section addresses topics such as the digestion and absorption of macronutrients, nutritional requirements for different age groups, methods for qualitative and quantitative determination of nutrients, milk intolerance and hypersensitivity, food additive safety, toxic elements, and radionuclides, and various nutritional policies.
