Digestion, Nutrients and You

All about Nutrients your body needs.

Do you ever get tired at work or school? Even when you’ve had enough rest it takes energy to keep your mind alert.

Our bodies were made to move, think, to breathe and in cold places, to stay warm. Without energy, you physically and mentally cannot do these things. Energy equals action. Also, growing takes energy along with your body’s ability to repair itself when you get hurt.

With all of this energy talk, where does it come from, the energy I mean? You guessed it, food. All of our energy comes from the food we eat.

The Digestive System

Our bodies have the superhero ability to change the food we eat into a form or a source our body can use. One of the ways is through our digestive system. This system breaks down the food from the time it hits your lips. This being the case, it is so important to chew your food extremely well to give the digestive juices in your mouth time to work. Besides the juices, chewing breaks the food down into smaller pieces, making it easier for the food to be processed through the rest of your digestive system.

Getting fresh airDigestion is helped when you get fresh air and exercise. I don’t mean you should do a marathon and then sit right away to eat or eat and then get on the treadmill. It’s better to have low impact shortly before and after your meals. Your stomach needs blood to digest your food and too much exercise can draw the blood away.

Another thing to consider is having regular mealtimes. Your digestive system will work better when you do, and you will also feel better. Starving yourself or going too long without a meal can make you crabby and result in low energy. Too much at one time can make you feel sluggish because your body must work extra hard to digest a larger amount. So, be kind to your body and eat regular, smaller portioned meals.

Certain emotions play havoc on your digestive system. These types of emotions anger, fear, or excitement during meal time can cause your stomach to ache. Other emotions such as, happy, stable and feel good emotions will help and make mealtime a more pleasant experience.

nutrientsWhat Are Nutrients?

According to, Merriam Webster’s Dictionary, Nutrients are: a substance or ingredient that promotes growth, provides energy, and maintains life.

“Tomatoes contain a lot of nutrients, among them vitamins C and B-complex and the minerals iron and potassium.”— Mayo Clinic Health Letter

“Nutrients include proteins, vitamins, minerals, carbohydrates, and oils.”


Hair, skin, and nails, along with muscles, your brain, and internal organs are largely made of protein. Therefore, it’s extremely important to get enough protein in your diet. Your body can not repair itself or work at full capacity without enough protein. 

Here are some good sources of protein

  • lean meats
  • eggs
  • milk, buttermilk, or powdered milk
  • yogurt

  • helps your body grow
  • repairs your body
  • fights infection
  • helps your body function properly
  • builds bones and cartilage
  • It’s a building block for blood

Every day you should be drinking milk or consuming some other food high in protein. Your body does not store protein, so a daily amount is required to stay healthy and on track.

Breakfast is especially important to get your intake of protein since that sets the tone and determines your energy level throughout the rest of the day. Giving your brain a head start will help you focus which then enables you to work more efficiently.

“The DRI (Dietary Reference Intake) is 0.8 grams of protein per kilogram of body weight or 0.36 grams per pound. This amounts to 56 grams per day for the average sedentary man. 46 grams per day for the average sedentary woman. is suggested.”


Definition of vitamin as is described in, Merriam Webster’s Dictionary. 

any of various organic substances that are essential in minute quantities to the nutrition of most animals and some plants, act especially as coenzymes and precursors of coenzymes in the regulation of metabolic processes but do not provide energy or serve as building units, and are present in natural foodstuffs or sometimes produced within the body.”

The amount of vitamins in food depends on several things. Ripeness, length of time stored, season, the temperature at the time of harvest, and how they are cooked. Eating a variety such as dark leafy greens, fruit and a meat will help your body get the different kinds of vitamins it needs.

Why does your body need mineralsMinerals

The roots of plants absorb and pull minerals and water from the soil through their roots. After that, they travel through the stem and into every part of the plant, including the portion of the plant we eat. You can also get minerals from animals that eat plants.

Exercise, swimming, mowing the lawn all take energy. And as we previously discussed, energy comes from the foods we eat. Foods that have sugar and starches in them are considered carbohydrate foods. Your body is a miracle worker and changes the starch and sugars into energy using minerals and vitamins.

Sweets such as candy, syrup, cake, and other refined type foods are not a healthy or wise choice. Since they are refined they have no nutritious value. You can get energy from these, not so healthy choices, but they have a higher calorie count and usually, get stored into fat. Plus it’s not a maintained energy, it’s more of a surge and then a crash.

Good source of carbohydrates

  • vegetables
  • whole-grain bread and cereals
  • fruits
  • brown rice
  • seeds
  • nuts
  • dried beans and peas
  • potatoes, sweet or regular
  • squash

  • give you energy for physical activities
  • maintains your body temperature
  • help your body use fats
  • allow your body to use proteins to grow and repair itself

Your entire body contains some water and needs it to do its job. Not having enough water can leave you dehydrated and make it so you’re more susceptible to colds and diseases. In hot weather when drinking ice water, be sure to sip it and drink slowly. This is easier on your body and does not shock it.

Eat plenty of fiberFiber

“Soluble fiber dissolves in water and becomes a gelatinous form, which may help to slow digestion and help your body absorb vital nutrients from foods. Insoluble fiber stays in its fibrous form, helps food pass through the digestive system, and adds bulk to the stool, which helps you to stay regular.” -Fiber Choice

Good source of fiber

  • most vegetables
  • whole grains
  • most fruits
  • seeds
