What does FEN mean in HOSPITALS

Electrolytes are minerals, such as sodium, potassium, chlorine and magnesium, which play an important role in helping to regulate the body's fluid balance, nerve and muscle function and acid-base balance. They are critical for healthy functioning of cells and organs.

Generally speaking, adults should aim to drink at least 8 glasses (2 liters) of water every day. This helps ensure that your electrolytes remain balanced as you lose water through sweating and urination. If you exercise heavily or live in a hot climate, it is recommended that you increase your intake of fluids to make sure that your electrolyte levels remain stable.

Carbohydrates provide one of the most important sources of energy for our bodies, with glucose being the primary form used by our cells for energy production. Carbohydrates are found in many foods such as grains and fruit, and act as a ready source of fuel for physical activities.

Eating a variety of healthy whole foods is the best way to get enough vitamins and minerals naturally from your diet. A wide range of fruits, vegetables, legumes, nuts and grains all contain essential nutrients like antioxidants and fiber that help keep your body functioning properly. Eating these foods on a regular basis will ensure that you get all the necessary vitamins and minerals needed for optimal health.

A balanced diet includes eating a variety of nutrient-rich foods in proportions appropriate for individual needs while maintaining an appropriate weight. This includes eating plenty of fruits and vegetables, whole grains, lean proteins such as fish or poultry; nuts; low-fat dairy products; legumes; healthy fats like olive oil; limiting unhealthy fats like those found in fried foods; drinking lots of water; minimizing sugar intake; avoiding unhealthful processed meals; and limiting alcohol consumption when possible.

Parenteral nutrition (PN) is a method of feeding someone intravenously instead of providing them with food orally or enterally (through tubes). It typically involves administering nutrients directly into a person's veins using infusions over extended periods of time either through a central line or peripheral line catheter. PN may be used when a person cannot consume enough calories orally or if their intestines are unable to absorb nutrients due to medical reasons such as surgery or illness.

While plain water remains the best choice for hydration purposes, some studies have shown moderate amounts of caffeine-containing beverages such as coffee can also contribute positively towards overall hydration status when consumed alongside other fluids throughout the day. However too much caffeine can lead to dehydration so it's important not to overdo it!

Potassium plays an important role in regulating heart rate by being involved in how electricity moves through cells within our heart muscle walls causing them to contract repeatedly. It also helps muscles work optimally by assisting with muscle contractions along with other electrolytes such as sodium and chloride.

Essential fatty acids (EFAs) are fat molecules that human bodies cannot produce on their own but need from dietary sources like nuts/seeds & fish oils etc., They are known primarily for their roles in brain development & cell growth/functioning & hormone production thus playing an integral part in immune system support & cardiovascular health. Therefore ensuring adequate EFA intake is key for overall well-being.
