Introduction
Nutrition is essential for good health and well-being. It provides the body with the nutrients it needs to function properly, and it can help to prevent chronic diseases such as heart disease, stroke, type 2 diabetes, and some types of cancer.
The Dietary Guidelines for Americans recommend that adults eat a variety of foods from all food groups, including fruits, vegetables, whole grains, lean protein, and low-fat dairy products. These foods provide the essential nutrients that the body needs, and they can help to maintain a healthy weight.
Macronutrients
Macronutrients are nutrients that the body needs in large amounts. They include carbohydrates, protein, and fat.
Carbohydrates are the body’s main source of energy. They are found in foods such as bread, pasta, rice, potatoes, fruits, and vegetables. Carbohydrates are broken down into glucose, which is then used for energy by the body’s cells.
Protein is essential for building and repairing tissues. It is found in foods such as meat, poultry, fish, eggs, dairy products, beans, and nuts. Protein is broken down into amino acids, which are then used to build new proteins in the body.
Fat is essential for hormone production and for absorbing vitamins. It is found in foods such as butter, margarine, oil, nuts, seeds, and avocados. Fat is broken down into fatty acids, which are then used for energy or to build new cells.
Micronutrients
Micronutrients are nutrients that the body needs in smaller amounts. They include vitamins and minerals.
Vitamins are essential for a variety of bodily functions, such as metabolism, immunity, and vision. They are found in foods such as fruits, vegetables, whole grains, and dairy products.
Minerals are also essential for a variety of bodily functions, such as bone health, muscle function, and nerve function. They are found in foods such as meat, poultry, fish, dairy products, beans, and nuts.
