According to the American Council on Exercise, men need 2–5% essential fat and women need 10–13% for basic physiological functioning. This critical component of your body, known as essential fat, is indispensable for survival, yet it is often misunderstood or conflated with general body fat.

According to the American Council on Exercise, men require at least 2 to 5 percent of their body composition to be essential fat, while women need 10 to 13 percent. A clear understanding of what is a definition of essential fat is crucial for anyone focusing on health, as this is the baseline fat needed for survival and normal bodily functions.

Carbohydrates are one of the three macronutrients, and while they sometimes get a bad reputation, a single gram of carbohydrate provides four calories of energy, making them a primary fuel source for the body. They are essential for many critical biological processes that sustain life and support overall health.

Historically, the discovery of vitamins occurred between 1910 and 1948, fundamentally changing our understanding of nutrition. To define this class of essential nutrients, a specific set of criteria make a compound a vitamin, distinguishing it from other vital substances like minerals and macronutrients.

Though often associated with citrus fruits and preventing the common cold, the physiological significance of vitamin C extends far beyond simple immune support. This essential water-soluble nutrient, also known as ascorbic acid, serves as a crucial cofactor for numerous enzymes, plays a central role in protecting the body's cells from oxidative stress, and is vital for the growth and repair of all body tissues. Without adequate intake, our bodies cannot function properly, leading to severe health complications.

According to the National Institute of Environmental Health Sciences, over half of U.S. adults have at least one preventable chronic disease often linked to diet, underscoring the crucial role of nutrition. The term function in nutrition refers to the specific roles nutrients play within the body to support life, facilitate growth, and maintain health.

Approximately 70% of the body's iron is found in red blood cells, within a protein called hemoglobin, highlighting its central role in oxygen transport. The physiological function of iron is remarkably diverse, extending far beyond simply carrying oxygen to tissues and muscles. This essential mineral is a fundamental component of hundreds of proteins and enzymes that underpin numerous biological processes, from cellular energy production to immune system activity.
