Carbohydrates, proteins, and fats are macronutrients that provide the body with energy and building blocks for various physiological processes. Vitamins, on the other hand, are micronutrients that are required in smaller amounts for specific bodily functions.

Vitamin A, also known as retinol, is essential for maintaining good vision, especially in dim light conditions. It plays a crucial role in the formation of rhodopsin, a pigment in the retina that allows us to see in low-light environments.

Dietary fiber, found in plant-based foods, is indigestible by the human body. It plays a vital role in promoting digestive health by adding bulk to stool, preventing constipation, and supporting the growth of beneficial gut bacteria.

Iron is a crucial mineral that plays a central role in the production of hemoglobin, the protein responsible for transporting oxygen from the lungs to various tissues and organs in the body.

The American Heart Association recommends limiting added sugar intake to no more than 6 teaspoons per day for women and 9 teaspoons per day for men. Added sugar refers to sugars that are added to foods during processing or preparation, excluding naturally occurring sugars found in fruits and vegetables.

Salmon is an excellent source of omega-3 fatty acids, particularly EPA and DHA, which are essential for heart and brain health. These fatty acids play a crucial role in reducing inflammation, improving cognitive function, and maintaining a healthy cardiovascular system.

Antioxidants are compounds that help protect cells from damage caused by free radicals, which are unstable molecules that can lead to oxidative stress and various health issues. Antioxidants neutralize free radicals, preventing them from causing harm to cells and tissues.

Vitamin D is essential for the absorption of calcium from the intestines. It helps maintain adequate levels of calcium in the blood, which is crucial for strong bones, teeth, and overall skeletal health.

The World Health Organization recommends consuming at least 400 grams (or 4-5 servings) of fruits and vegetables per day. This recommendation aims to promote overall health and well-being by providing essential vitamins, minerals, fiber, and antioxidants.

Bananas are a rich source of potassium, an essential mineral that plays a vital role in maintaining fluid balance, regulating blood pressure, and supporting nerve and muscle function.

Carbohydrates are the body's primary source of energy. They are broken down into glucose, which is then used by cells for fuel. Carbohydrates also help regulate blood sugar levels and provide fiber, which is important for digestive health.

Saturated fats are a type of unhealthy fat that can raise cholesterol levels and increase the risk of heart disease. Monounsaturated and polyunsaturated fats, on the other hand, are considered healthy fats that can help lower cholesterol levels and improve heart health.

The American Heart Association recommends limiting sodium intake to no more than 2,300 milligrams per day for adults. High sodium intake can contribute to high blood pressure, which is a major risk factor for heart disease and stroke.

Eggs are an excellent source of high-quality protein, providing all nine essential amino acids that the body cannot produce on its own. Protein is crucial for building and repairing tissues, producing enzymes and hormones, and supporting immune function.

Water is essential for regulating body temperature. It helps sweat evaporate from the skin, which cools the body down. Water also helps transport nutrients and oxygen to cells and removes waste products.
