Introduction to Essential Nutrients
Maintaining optimal health requires a balanced intake of essential nutrients. These nutrients can be categorized into two main groups: micronutrients and macronutrients4. Micronutrients, which include vitamins and minerals, are needed by the body in smaller quantities, while macronutrients, such as proteins, carbohydrates, and fats, are required in larger amounts4. All of these essential nutrients play crucial roles in supporting various bodily functions and overall well-being.
Types of Essential Nutrients: Micronutrients and Macronutrients
Micronutrients, which consist of vitamins and minerals, are essential for the body’s proper functioning4. There are 16 essential minerals and 13 vitamins that the body needs to maintain health4. These micronutrients assist in various processes, such as energy metabolism, immune system support, and bone development5.
Macronutrients, on the other hand, provide the energy the body requires for daily activities4. These include carbohydrates, proteins, and fats, each of which offers a different caloric value per gram4. Carbohydrates and proteins both provide 4 calories per gram, while fats offer 9 calories per gram4. Additionally, water, though not a macronutrient, is a crucial component for overall health, with adults consuming over 2 liters per day on average4.
Maintaining a balanced intake of both micronutrients and macronutrients is essential for optimal health and well-being5. Research consistently finds that most Americans don’t get enough vitamins and minerals in their diets6, and more than 50% of adults have one or more diet-related chronic conditions, such as obesity, type 2 diabetes, cardiovascular disease, or cancer6.
“At least 30 vitamins, minerals, and dietary components are essential for the body and cannot be manufactured in sufficient amounts internally.”5
Understanding the role of essential nutrients and incorporating a diverse range of nutrient-rich foods into your diet can help support overall health and reduce the risk of chronic diseases65.
Vitamins and Their Important Functions
Vitamins are essential micronutrients that play a vital role in maintaining overall health and well-being7. There are 13 essential vitamins necessary for the body to function properly7. These vitamins can be divided into two main categories: fat-soluble and water-soluble.
Fat-Soluble Vitamins and Their Sources
The four fat-soluble vitamins are A, D, E, and K7. These vitamins are absorbed and stored in the body’s fatty tissues, and they play crucial roles in various bodily functions, such as vision, bone health, and blood clotting8. Vitamin A from animal sources helps in night vision and immune function, while plant-based vitamin A prevents cell damage and age-related macular degeneration8. Vitamin D, primarily obtained through sun exposure and fish consumption, is vital for bone health and immunity8. Vitamin E, an antioxidant, maintains cell health and is found in seeds, nuts, and vegetable oils8. Vitamin K necessary for blood clotting is found in leafy greens and soy-based products8.
Water-Soluble Vitamins and Their Sources
The water-soluble vitamins include vitamin C and the B-complex vitamins7. These vitamins are not stored in the body and need to be replenished regularly through dietary sources7. Vitamin C aids in bone, skin, and muscle development, sourced from bell peppers, papaya, and leafy greens8. The B-complex vitamins, such as thiamin, riboflavin, niacin, and vitamin B6, play crucial roles in energy metabolism, nerve function, and red blood cell production8. Vitamin B12, which can be stored in the liver for many years7, is essential for the proper functioning of the nervous system and the formation of red blood cells8.
To maintain optimal health, it is essential to consume a balanced diet rich in a variety of fruits, vegetables, whole grains, and lean proteins to ensure adequate vitamin intake7. Vitamin deficiencies can lead to various health problems, and not consuming enough of these essential nutrients can increase the risk of heart disease, cancer, and osteoporosis7.
“Vitamins are essential for maintaining proper bodily function and overall health. Ensuring a well-balanced diet is the best way to meet your daily vitamin needs.”
In addition to dietary sources, some individuals may require vitamin supplements to address specific deficiencies or to meet increased needs, such as during pregnancy or for those with certain medical conditions7. However, it is crucial to avoid overdosing on fat-soluble vitamins, as they can have harmful effects if consumed in excess7.
Understanding the different types of vitamins and their sources can help individuals make informed choices about their dietary intake and ensure that they are meeting their daily vitamin requirements7. By prioritizing a nutrient-dense diet and, if necessary, using supplements judiciously, individuals can support their overall health and well-being789.
Minerals: Major and Trace Elements
Minerals are the second type of essential micronutrients, playing a crucial role in maintaining optimal health10. These vital nutrients are divided into two main categories: major minerals and trace minerals10. Understanding the functions and food sources of these mineral groups can help ensure a balanced and nutrient-rich diet.
Major Minerals: Functions and Food Sources
Major minerals, such as calcium, phosphorus, magnesium, sodium, potassium, and chloride, are required by the body in larger amounts, typically over 100 milligrams (mg) per day11. These essential minerals help the body perform crucial functions, including maintaining water balance, supporting healthy skin and bones, and regulating blood pressure11. Dairy products, leafy greens, nuts, seeds, and fortified foods are excellent sources of major minerals11.
Sodium, potassium, and chloride, known as electrolytes, play a vital role in water balance within the body11. Sodium and chloride are the primary electrolytes outside cells, while potassium is the main electrolyte inside cells11. Maintaining a proper balance of these electrolytes is essential for various bodily functions.
| Major Minerals | Functions | Food Sources |

In some cases, healthcare providers may recommend mineral supplements for individuals with specific health conditions or dietary restrictions10.
“A balance of both major and trace minerals can be achieved by consuming a varied diet rich in red meats, seafood, dairy products, nuts, seeds, vegetables, and fortified foods.”
Protein: A Macronutrient for Growth and Development
Protein is a vital macronutrient that plays a crucial role in the growth, development, and overall function of the human body12. Approximately 16% of the average person’s body weight is comprised of protein, which is essential for building and maintaining muscles, tissues, and cells12. This essential nutrient is responsible for a variety of crucial functions, including ensuring the proper growth and development of muscles, bones, hair, and skin, as well as forming antibodies and hormones.
Protein can be obtained from a wide range of dietary sources, including red meats, poultry, fish, beans, legumes, eggs, dairy products, and some grains13. The National Academy of Medicine recommends a minimum of 0.8 grams of protein per kilogram of body weight per day13. For a 140-pound person, this translates to about 50 grams of protein daily, while a 200-pound person would require approximately 70 grams per day13. The acceptable protein intake ranges from 10% to 35% of total daily calories13.
While meats and seafood tend to have the highest protein content14, those following a vegan or vegetarian diet can also get enough protein from plant-based products14. Typically, a person who eats a balanced diet that includes lean proteins, vegetables, fruits, complex carbohydrates, and water will get the essential nutrients they need14.
“Protein is the foundation for growth, repair, and maintenance of all the cells in your body. It’s essential for life.”

Carbohydrates: Complex and Simple
Carbohydrates are a crucial macronutrient, providing the body with energy to power all its cells and tissues18. However, not all carbohydrates are created equal – there are two distinct types: complex and simple. Understanding the differences between these can help you make healthier choices for your diet.
Complex carbohydrates, also known as starches, are larger, more intricate molecules that take longer for the body to break down and digest19. These complex carbs are higher in fiber and digest more slowly, providing a steadier supply of energy19. Good sources of complex carbohydrates include whole grains, legumes, fruits, and vegetables.
On the other hand, simple carbohydrates are smaller, more easily digestible molecules that provide a quick burst of energy20. These simple carbs can be either naturally occurring, like the sugars found in fruits and milk, or added, like the sweeteners found in processed foods20. While simple carbs may provide a quick energy boost, they often lack the important nutrients and fiber found in complex carbs.
- The American Heart Association advises limiting added sugars to no more than 25 g per day for people assigned female at birth (AFAB) and 36 g per day for people assigned male at birth (AMAB)18.
- The USDA recommends filling half your plate with fruits and vegetables, one-quarter with whole grains, and one-quarter with protein for a healthy balanced diet18.
- Fiber-rich foods like whole grains, fruits, vegetables, and legumes provide essential nutrients and promote digestive and heart health19.
- Refined grains like white bread and pasta lack important B vitamins and dietary fiber, so it’s best to choose whole-grain alternatives20.
While simple carbs may provide a quick energy boost, it’s important to primarily choose nutrient-dense, complex carbohydrates to support overall health and well-being18. By understanding the differences between these two types of carbohydrates, you can make informed choices to fuel your body and maintain a balanced, healthy diet.
“Carbohydrates are the body’s main source of energy, but the type of carbs you choose makes a difference. Complex carbs like whole grains, fruits, and vegetables are the healthiest options.”
Water: The Most Vital Nutrient
Water is a fundamental component of the human body, comprising around 70% of our total body weight21. It is an essential nutrient that plays a crucial role in maintaining various bodily functions, including flushing out toxins, shock absorption, nutrient transportation, and preventing constipation21. Many health experts recommend drinking at least four to six cups of water per day to stay hydrated, though individual needs may vary based on factors like health conditions, activity levels, and environmental factors21.
Staying Hydrated: Importance and Sources
Adequate water intake is vital for overall health and body function. Water accounts for 50% to 60% of the body’s mass, making it the most abundant constituent of the body22. The recommended daily fluid intake is 3.7 liters (101.4 fluid ounces or 13 cups) for men and 2.7 liters (74.4 fluid ounces or 9 cups) for women22. However, the specific amount needed can vary based on factors such as age, activity level, and health conditions23.
The best sources of water are unsweetened tap water or bottled water, as well as fruits and vegetables with high water content21. Individuals should aim to avoid getting their water intake from sugary drinks like soda, sweetened teas, and fruit juices, as these can contribute to dehydration and other health problems21. To enhance the flavor of water, you can try adding fruit slices, coffee ice cubes, bullion cubes, cucumber slices, fresh mint leaves, or flavor-enhancing products21.
Proper hydration is essential for maintaining overall health and well-being. By incorporating a variety of water-rich foods and beverages into your diet, you can ensure that your body receives the vital nutrient it needs to function at its best22. Consulting with a healthcare professional can also provide personalized guidance on your individual hydration needs23.
“Drinking fluids represent about 81% of total water intake, while 19% is provided by foods.”22
