Why do I need to eat that?

Do you ever think about why you eat? The easy answers are because you are hungry, tired and your stomach is rumbling. Sometimes you might also eat because you are bored, sad or happy, just because it’s lunchtime, or because that chocolate-covered donut looks so good.

Those are some of the emotional and physical reasons why you eat, but do you ever put much thought into why your body needs food? Not just any food, by the way, but healthy, good-for-you food? Why is good nutrition important?  I hope the way we talk about “your health” here in Indianapolis at Meridian Chiropractic Clinic makes you ask that question more and more.

The foods you eat provide the energy your body needs to function. Just like you need to put fuel in your car or recharge your cell phone battery, your body needs to be fed energy-providing foods every day. The main form of energy for your body is carbohydrates.

Your body has the easiest time digesting carbohydrates like sugar and starch. Carbohydrates are broken down into individual glucose, fructose or galactose units. Glucose is your body’s favorite form of energy. If you don’t get enough carbohydrates, your body can make glucose from protein or fat — and if you get too many carbohydrates, your body is very good at storing them as fat.  Too much fat as storage device increases your chance of back pain.

Protein in the foods you eat is broken down into individual amino acids. Your body uses the amino acids to build and repair the various parts of your body. Your muscles contain lots of protein, and you need to replenish that protein through your diet. Your body also needs protein for components of your immune system, hormones, nervous system, and organs.

Another raw material your body needs is calcium. Calcium has several functions in your body, but it’s best known as the mineral that is stored in your bones and teeth. You need calcium from your diet to keep your bones and teeth strong.

Your body also needs good fats to be healthy. Membranes that contain fats surround all the cells of your body. Your brain has fatty acids, and fats are also needed to signal hormones.

Vitamins and minerals you get from your diet are just as important as carbohydrates, protein and fats; however, you only need them in small amounts. Vitamins and minerals usually function as co-enzymes, which means they help chemical reactions in the body happen a lot faster. For example, many of the B complex vitamins help your body burn carbohydrates for energy. Vitamin A is needed for vision, zinc is involved in many metabolic processes, and vitamin C helps keep connective tissue strong and your immune system functioning.

Your diet needs to provide adequate amounts of all of these “little helpers.” A healthy, balanced diet will provide you with lots of vitamin and minerals. An unhealthy diet may make your body deficient in one or more of these helpers.

Good nutrition provides more than energy, structural components, vitamins and minerals. There are other substances in the foods that you eat that have become better known over the last few years.

Phytochemicals are found in the colorful parts of fruits and vegetables. Although they aren’t required for body functioning, they may have a very powerful impact on your health. For example, quercetin (found in red apples) functions like an antihistamine and as an anti-inflammatory effect. Resveratrol, found in grape skins and seeds, is a powerful antioxidant.

Antioxidants help protect your body from damage that comes from the sun, pollution, smoke, and poor dietary choices. They are found in the phytochemicals of fruits and vegetables, as well as some vitamins and amino acids.

A healthy diet will give your body the right amount of energy, enough raw materials and all of the “little helpers” you need to stay healthy. Good nutrition will also provide phytochemicals and antioxidants that will help keep you feeling young, looking great, and perhaps even disease-free. A bad diet will give you too many or too few calories, not enough vitamins and minerals, and will actually make you need more of the antioxidants that you aren’t getting.

So the next time you think that chocolate covered donut looks good, think about what you are actually putting in your body and eat a piece of fruit instead.
