Study Notes
Essential Nutrients
Essential nutrients are vital elements required by the body to function optimally. These nutrients come from various sources such as food, supplements, and sometimes intravenous infusions. There are four main categories of essential nutrients: vitamins, minerals, proteins, and carbohydrates. Let's delve deeper into each category.
Vitamins
Vitamins are organic compounds found in foods that are necessary for normal growth, development, and maintenance of our bodies. They can also help protect against diseases. For example, vitamin C boosts immunity and helps wounds heal faster. It is essential to consume a variety of colorful fruits and vegetables daily to get all the different types of vitamins needed for optimal health. Some notable vitamins include A, B, C, D, E, K, and folate[1,5].
Minerals
Minerals are inorganic materials that play essential roles in the body. Some common minerals include calcium, iron, magnesium, phosphorus, potassium, sodium, zinc, iodine, fluoride, manganese, selenium, chromium, copper, molybdenum, and silicon. Calcium is important for bone health and nerve signaling; iron is crucial for blood production; while magnesium supports muscle and heart function. Getting enough minerals requires consuming a balanced diet with plenty of whole foods like leafy greens, nuts, seeds, fish, and legumes.
Proteins
Proteins are large molecules made up of amino acids. They have multiple functions including building, repairing tissues, producing enzymes, removing waste products, and helping muscles contract. Additionally, proteins serve as precursors to hormones and other biologically active molecules. Sources include lean meats, poultry, fish, eggs, dairy products, soy products, beans, peas, lentils, nuts, and seeds. Incorporating protein-rich foods into meals and snacks throughout the day will ensure appropriate intake.
Carbohydrates
Carbohydrates provide energy in the form of glucose, which the brain uses as fuel. They are divided into two categories: simple sugars and complex carbohydrates. Simple sugars, such as fructose and glucose, are found in sweet foods like fruits, honey, cakes, and candies. Complex carbohydrates, also known as starches, are found in grains, breads, cereals, rice, pasta, starchy vegetables, and legumes. Consuming whole grain varieties more often can improve overall health due to their fiber and nutrient content.
