Study Notes
Food Components: Understanding Carbohydrates, Proteins, Fats, Vitamins, and Minerals
Carbohydrates
Carbohydrates are one of the main sources of energy for our bodies. They come from various forms of sugar and starch found in foods such as grains, fruits, vegetables, legumes, milk products, and sugars. Carbohydrates can be classified into two types: simple carbohydrates or monosaccharides (such as glucose and fructose) and complex carbohydrates or polysaccharides (such as starch and fiber). Simple carbohydrates are rapidly absorbed by the body and provide a quick burst of energy, while complex carbohydrates take longer to digest and release their energy more slowly, helping to maintain steady blood sugar levels.
Proteins
Proteins are essential building blocks for our bodies, serving many functions including growth, tissue repair, immune function, and enzyme production. They are made up of amino acids, which can either be synthesized within the body or obtained through dietary sources like meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds. The human body needs 20 different types of amino acids to create proteins, nine of which must come from food because they cannot be produced internally. Amino acids combine in long chains called peptides and form proteins, which serve various roles in the body, such as supporting muscle growth, maintaining skin, hair, and nails, and contributing to hormone production.
Fats
Fats play an important role in providing energy, maintaining cell membranes, and absorbing fat-soluble vitamins. They are classified into three main categories: saturated fats, unsaturated fats, and trans fats. Saturated fats are generally solid at room temperature and found mostly in animal products like meat and dairy, while unsaturated fats are liquid at room temperature and commonly found in plant-based oils, nuts, seeds, and fish. It is recommended to consume a balanced ratio of these different types of fats to optimize health outcomes.
Vitamins
Vitamins are organic compounds that play vital roles in regulating metabolism, supporting immunity, and maintaining overall health. There are two types of vitamins: water-soluble (vitamin C, B vitamins, and vitamin A), which can be stored in small amounts in the body but require daily replenishment through diet, and fat-soluble (vitamin K, vitamin E, and vitamin D), which can be stored in the liver and adipose tissue for future use. Foods rich in vitamins include fruits, vegetables, whole grains, lean proteins, and dairy products.
Minerals
Minerals are essential nutrients that support numerous physiological functions, including bone growth, oxygen transport, muscle function, nerve transmission, and immune response. Major minerals include calcium, potassium, sodium, magnesium, phosphorus, chloride, and sulfur, while trace minerals include iron, zinc, copper, iodine, selenium, fluoride, manganese, molybdenum, nickel, and silicon. These minerals are primarily obtained through dietary intake of a variety of foods, including leafy greens, whole grains, dairy products, meats, seafood, eggs, and legumes.
