“Proper nutrition is not just about calories, it’s about getting the right balance of macronutrients and micronutrients to support your body’s overall health and function.”

Protein: Building Blocks of the Body

Protein is an essential macronutrient that plays a vital role in the human body. It serves as the building blocks for muscles, bones, hair, and skin, and is also involved in the production of hormones, enzymes, and antibodies. The body requires a variety of amino acids to form complete proteins, which can be obtained from both animal-based and plant-based sources.

Functions of Protein

Protein is crucial for a multitude of bodily functions. The daily recommended intake of protein for healthy adults is 10% to 35% of total calorie needs⁵, and one gram of protein supplies 4 calories⁵. Protein is essential for growth, repair, and maintenance of body tissues, as well as the proper functioning of the immune system. Additionally, it plays a role in energy production and the regulation of various metabolic processes.

Healthy Sources of Protein

Protein can be obtained from a variety of food sources, both animal-based and plant-based. An ounce (30 grams) of most protein-rich foods contains 7 grams of protein⁵. Animal-based sources such as meat, fish, eggs, and dairy are considered complete proteins as they contain all the essential amino acids. Plant-based sources, including beans, soy, nuts, and some grains, are also valuable protein sources, though they may be considered incomplete proteins as they lack certain essential amino acids⁶.

It’s important to note that children and teens may require different amounts of protein depending on their age and stage of development⁵. The US Department of Agriculture’s MyPlate guide can aid in making healthy eating choices and ensuring a balanced intake of protein and other essential nutrients⁵.

Protein-Rich Food	Protein Content (per 4-ounce serving)
Chicken Breast	35 grams
Salmon	29 grams
Lentils	18 grams
Greek Yogurt	20 grams
Almonds	8 grams

The National Academy of Medicine suggests a minimum of 0.8 grams of protein for every kilogram of body weight per day, equivalent to around 7 grams for every 20 pounds of body weight⁷. For a 140-pound individual, the recommended protein intake is about 50 grams per day, while for a 200-pound individual, it is around 70 grams per day⁷.

“Protein is essential for the growth and repair of body tissues, as well as the proper functioning of the immune system. Incorporating a variety of high-quality protein sources into your diet can support overall health and well-being.”

It’s important to remember that while animal-based protein sources are generally more easily absorbed and utilized by the body, plant-based proteins can also be an excellent addition to a balanced diet⁶. Whole grains, for example, contain more protein than their refined or “white” counterparts⁵.

Ultimately, a diverse, nutrient-dense diet that includes a variety of protein-rich foods can help ensure that the body’s protein needs are met and support overall health and well-being⁵⁷⁶.

Carbohydrates: Fuel for Energy

Carbohydrates are a crucial macronutrient that provides the body with its primary source of energy. They can be categorized into two main types: simple carbohydrates, such as those found in white bread and added sugars, and complex carbohydrates, which are present in whole grains, vegetables, and fruits⁸. The Dietary Guidelines for Americans recommend that 45-65% of daily calories should come from complex carbohydrates⁸.

Complex carbohydrates are essential for supporting the immune system, brain function, the nervous system, and digestive health⁹. Adults are recommended to consume 25 to 30 grams of fiber every day, but most people only get half that amount⁹. Fiber helps regulate blood sugar, lower cholesterol, and aid in digestion⁹.

On the other hand, simple carbohydrates, or added sugars, should be limited. The American Heart Association recommends no more than 25 grams (6 teaspoons or 100 calories) per day of added sugar for most people assigned female at birth (AFAB) and no more than 36 grams (9 teaspoons or 150 calories) per day for most people assigned male at birth (AMAB)⁹. Limiting refined foods and those with added sugar is crucial to maintaining healthy blood sugar levels and preventing weight gain⁹.

Carbohydrate intake can vary depending on factors such as age, sex, medical conditions, activity level, and weight goals⁹. It is advised to choose complex carbohydrates more frequently over simple carbs to receive more nutritional benefits⁹.

“Carbohydrates are the body’s primary source of energy, and choosing the right types can support overall health.”
