Understanding Nutrients in Food

Study Notes

Nutrients in food are substances that nourish the body and are essential for maintaining general health and physiological functions.
Major nutrients in human nutrition are divided into three categories: macronutrients, micronutrients, and water.
Macronutrients are required in large amounts and include carbohydrates, proteins, fats/oils, and water.
Carbohydrates are the primary source of energy in most diets and include starches, fiber, and sugars.
Sweet foods should be consumed minimally as they do not provide other nutrients and may increase the risk of overweight.
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen atoms and provide energy for metabolic processes in the body.
Carbohydrates can be found in a wide range of foods, including grains, fruits, vegetables, legumes, and dairy products.
Carbohydrates come in several forms, including simple carbohydrates (sugars) that are quickly digested and provide a rapid source of energy.
Proteins are essential for building body mass, boosting immunity, and regulating various body functions.
Fats/oils are important for keeping the body warm and are a source of energy.
Micronutrients include vitamins and minerals that are required in smaller quantities for various physiological functions.
Water is essential for maintaining hydration and supporting numerous bodily functions.
