Carbohydrates, proteins, and fats are the three macronutrients that provide the body with energy and building blocks for growth and repair. Vitamins are micronutrients that are essential for various bodily functions but do not provide significant energy.

Carbohydrates are the body's primary source of energy. They are broken down into glucose, which is used for immediate energy or stored as glycogen for later use.

Complete proteins contain all nine essential amino acids that the body cannot produce on its own. Eggs are an excellent source of complete protein, along with other animal-based foods like meat, fish, and poultry.

According to dietary guidelines, adults should aim for 5-9 servings of fruits and vegetables per day. This helps ensure a balanced intake of essential vitamins, minerals, and fiber.

Vitamin K is essential for blood clotting and wound healing. It helps in the production of proteins involved in these processes.

Dietary fiber is a type of carbohydrate that cannot be digested by the body. It helps promote digestion by adding bulk to stool, preventing constipation, and supporting a healthy gut microbiome.

Calcium is a crucial mineral for maintaining strong bones and teeth. It also plays a role in muscle contraction, nerve transmission, and blood clotting.

Adults should aim to drink around 2-3 liters of water per day to stay hydrated and support various bodily functions.

Frying is generally considered a less healthy cooking method compared to others like baking, boiling, or steaming. It involves submerging food in hot oil, which can lead to the formation of harmful compounds and increase the risk of certain health issues.

A vegan diet is one that excludes all animal products, including meat, poultry, fish, eggs, and dairy. Vegans follow this diet for ethical, environmental, or health reasons.

Hemoglobin is a protein found in red blood cells that carries oxygen from the lungs to the rest of the body and transports carbon dioxide back to the lungs.

Adults should aim to consume no more than 1,500-2,000 mg of sodium per day to maintain a healthy blood pressure and reduce the risk of heart disease.

Vitamin A is crucial for maintaining healthy vision, particularly night vision. It helps the retina convert light into electrical signals that are sent to the brain.

A whole food diet focuses on consuming unprocessed, nutrient-rich foods in their natural state. It includes fruits, vegetables, whole grains, lean proteins, and healthy fats.

Protein is not a type of carbohydrate. Carbohydrates are composed of sugar molecules, while proteins are composed of amino acids.
