Good nutrition is important for every living organism. Healthy eating, coupled with an active lifestyle, has long been established as a sure way to live a long, full life. It may seem impossible to get the right amount of these nutrients in your diet, but the trick is that you’re already eating all of these.
Carbohydrates give you the fuel that you need to power your body. The human body couldn’t do anything without them. Anywhere between 45 and 75 percent of your diet should come from carbohydrate-rich foods. Glucose fuels the body’s chemical processes. Polysaccharides are composed of monosaccharide molecules. They are called complex carbohydrates and are found in fruit, vegetables, and grain. Starch is the most important polysaccharide. Carbohydrates prevent dehydration.
Protein is another important source of energy for the body. The protein consists of amino acids that act as the body’s main building blocks for tissues, such as muscle, skin, bone, and hair.
Fat is an energy source that when consumed, increases the absorption of fat-soluble vitamins including vitamins A, D, E and K. Twenty to 35 percent of your daily intake should come from fat. Fat often has a bad name as a nutrient, but there are certain nutritional functions that can only be accomplished by fat. Vitamins such as A, D, E and K, are properly absorbed by the body only in the presence of fat. Fat also provides protection against disease and injury.
Vitamins and minerals
This one’s a twofer. The reason for this is that vitamin D and calcium work in tandem to promote bone health throughout the body. Vitamin C is an antioxidant. It protects the enzymes throughout the body from degradation in the presence of oxygen. Vitamin C aids in the healing of wounds and the prevention of sickness. Consumption of extra vitamin C can hasten recovery from the common cold.
As your body creates and maintains its trillions of cells, folic acid helps the process. Folic acid also helps to stabilize the DNA and RNA throughout your body.
You should get at least 8 mg of iron from a variety of dietary sources each day to replenish the iron that leaves your body.
Zinc is a crucial component of many of the body’s enzymes and proteins. Zinc plays a key role in the enzymes that regulate carbon dioxide in the body. Zinc has a key function in the brain’s synapses and is necessary in many ways for every cell in the body.
Sodium helps to maintain fluid volume outside of the cells and helps cells to function normally.
Calcium helps to maintain and build strong bones and teeth.
Water helps to maintain homeostasis in the body and transports nutrients to cells. Water also assists in removing waste products from the body.
You’ve probably heard that you can live for weeks without food but only days without water. That’s because water is the most important essential nutrient.
Even though humans can’t digest fiber (cellulose), it plays a vital role in regulating the movement of food and nutrients through your body. The right balance of fiber in your diet will keep your gastrointestinal tract healthy for years to come.
