Proteins and amino acids
Proteins are fundamental components of the human diet and are essential for life. They are involved in nearly every biological process, from building and maintaining body tissues, such as muscles, skin, and organs, to supporting the immune system, synthesizing enzymes and hormones, and transporting nutrients and oxygen throughout the body. Every cell in the human […]
Protein measurements
Proteins are essential macronutrients that play a vital role in the growth, repair, and maintenance of the human body. Alongside carbohydrates and lipids, proteins can also serve as a source of energy in the diet when other energy sources are insufficient. Given their biological importance, evaluating the protein quality of food is a key aspect […]
Cholesterol
Cholesterol is a unique and biologically essential lipid in the human body that plays a crucial role in numerous physiological processes. Despite its controversial reputation in public discourse, it is indispensable for human health, from facilitating the transport of nutrients to regulating cellular functions. First identified in 1769 by French chemist François Poulletier de la […]
Fats and fatty acids
Fats are an essential component of the human diet, contributing not only to overall health but also to the sensory qualities of food, such as taste, aroma, and texture. Alongside proteins and carbohydrates, fats serve as one of the three primary macronutrients, providing a dense source of energy and supporting the absorption of fat-soluble vitamins […]
Carbohydrates
Carbohydrates, alongside proteins and fats, are one of the three major macronutrients that form the foundation of a healthy, balanced diet. They serve as the body’s primary source of energy and play a crucial role in numerous metabolic processes. Despite their importance, carbohydrates, particularly sugars, have become the subject of ongoing debate in nutrition science […]
Digestion and basic nutrients
The digestion and absorption of nutrients are fundamental processes necessary for the survival of all living organisms. Over millions of years, these functions have evolved into the highly specialized and intricate tasks performed by the gastrointestinal system. The ability to break down food and extract its nutrients is essential for energy production, cellular function, and […]
