What are Micro-nutrients vs Macro-nutrients?

Micro-nutrients are different from macro-nutrients (like carbohydrates, protein, and fat) because they are necessary only in very tiny amounts. Nevertheless, micronutrients are essential for good health, and micronutrient deficiencies can cause serious health problems. Micro-nutrients include such dietary minerals as zinc and iodine, and they are necessary for the healthy functioning of all your body's systems, from bone growth to brain function.

What Micro-nutrients are and Their Role in Your Health

Micro-nutrients are what are commonly referred to as "vitamins and minerals." Micro-nutrients include such minerals as fluoride, selenium, sodium, iodine, copper, and zinc. They also include vitamins such as vitamin C, A, D, E, and K, as well as the B-complex vitamins.

As mentioned, micro-nutrients are different from the macro-nutrients protein, carbohydrate and fat, and micro-nutrients are called "micro"-nutrients because your body needs only very small quantities of them for survival. However, if your body doesn't get the small quantities of micro-nutrients that it needs, serious health problems can result.

Micro-nutrients are vital to the proper functioning of all of your body's systems. Sodium, for instance, is responsible for maintaining the proper fluid balance in your body; it helps fluids pass through cell walls and helps regulate appropriate pH levels in your blood.

Getting Enough Vitamins and Minerals in Your Diet?

Getting enough micro-nutrients in your diet isn't hard. Eat a balanced diet including plenty of nuts, whole grains, and green leafy vegetables. Eat plenty of colorful fruits and vegetables, like red cherries, purple grapes, yellow bananas, and orange carrots. The more colorful your diet, the better.

It's easy to include more fruits and vegetables in your diet. Eat fruit salads for dessert instead of sweets. Prepare your own homemade soups and salads and include two or more vegetable side dishes with each meal.


Macro-nutrients constitute the bulk of the food we eat. The macro-nutrients are proteins, carbohydrates, and fats.

Proteins - Proteins are called building blocks of life. It is what most of our body is made up of. Proteins themselves are made of amino acids. Some good sources of protein include fish, poultry meat, legumes, soy, eggs, milk and milk products.

Carbohydrates - Carbohydrates are made up of sugar or starches. They are the main energy providers for our body. Excess carbohydrates are converted into fat and stored in our body. All foods have carbohydrates in some measure.

Fats - Fats are substances that your body stores for future use. Although most people think that fats are to be avoided altogether, there is a distinction to be made here. There are good fats and bad fats. Bad fats are to be avoided and good fats are to be eaten. Good fats are very much necessary for the proper functioning of the body.

Proteins, carbohydrates, and fats are to be eaten in proper proportion. If they are not, lifestyle diseases will affect you.

Bioavailability of Nutrients – The Nutrition of Micro-nutrients

The bioavailability of food consumed is an important issue in nutrition. But, trying to calculate quantitatively how much of each known nutrient you are getting out of your diet is both a waste of time and impossible to do. It is recommended that you do not try to quantify your intake of specific Micro-nutrients from your diet.

Highlights of Bioavailability of Nutrients – The Nutrition of Micro-nutrients:

  • Good nutrition from eating a healthy diet is the foundation of the biomedical model of natural health.
  • Any change in your diet, however small, that improves your natural health is a step in the right direction.
  • Micro-nutrients include vitamins, minerals, phytochemicals, and water.
  • Micro-nutrients do not provide any energy to the body.
  • You improve your nutrition and natural health by choosing to eat healthier foods, then the food you are currently eating.

Poor nutrition is the result of consuming too little good food, or too much of the wrong kinds of food, on a regular basis. Food science, a root cause of poor nutrition, transforms unnatural foods into garbage that fills the belly while developing excessive human appetites for fat, sugar, and salt. Avoiding poor nutrition simply means refusing to eat junk food.

Nutrients compete with other nutrients for absorption. Some nutrients will enhance/reduce the amounts of other nutrients being absorbed by your body.
