What are the five components of food known as nutrients?

  1. Proteins, fats, carbohydrates, vitamins, minerals

  2. Oils, sugar, salt, water, proteins

  3. Carbohydrates, sugars, acids, minerals, fibers

  4. Fats, vitamins, antioxidants, fibers, minerals

The correct answer is: Proteins, fats, carbohydrates, vitamins, minerals

The five components of food known as nutrients are indeed proteins, fats, carbohydrates, vitamins, and minerals. Each of these plays a vital role in maintaining health and supporting bodily functions. Proteins are crucial for building and repairing tissues, serving as enzymes and hormones, and supporting immune function. Fats provide a dense source of energy, help absorb fat-soluble vitamins, and are essential for cell membrane structure. Carbohydrates are the body's primary energy source, with simple carbohydrates providing quick energy and complex carbohydrates offering sustained energy. Vitamins are organic compounds necessary for various biochemical functions, and they often play roles in immune defense, energy production, and blood clotting. Lastly, minerals are inorganic elements that support numerous physiological processes, including bone health and fluid balance. The other choices include various components that do not represent the five major categories of nutrients recognized in nutrition science. For example, oils and sugar, while they have nutritional values, do not encompass the broader categories of nutrients.
