Micronutrients and macronutrients

6 essential nutrients and why you need each one to stay healthy

 

Proper diet is super important to maintaining optimal, radiant health, because most of it is ensuring the adequate intake of essential nutrients needed to support life-crucial cellular processes.

 Scientists agree that there are six primary nutrients, which our human body cannot produce by itself. Therefore we need to get them from a range of foods in order to stay healthy.

 

Six essential nutrients

The World Health Organization (WHO) classifies nutrients as either micro- or macronutrients. Micronutrients are those needed in small doses, such as for example vitamins and minerals.

Macronutrients, on the other hand, are those that are often consumed in large quantities, including proteins, fats and carbohydrates. Water also belongs to this group.

We need to eat all six of them, as each one supports a wide scale of important cellular processes, from protein synthesis to a very important function as reproduction.

Here comes the specific functions, health benefits and some food sources for each one:

 

Vitamins

Vitamins are organic compounds that the human body requires in relatively small quantities. This is because it either does not produce enough of the nutrient or does not produce that nutrient at all.

For instance, humans can make vitamin D from sunlight through their kidneys and vitamin K through gut bacteria. But these organs make so little that a person should still eat foods rich in the nutrients or take supplements in order to avoid nutritional deficiencies.

Some of the important functions and health benefits of vitamins include boosting immune health, slashing cancer risk, strengthening bones, supporting blood circulation and maintaining efficient neural connections.

There are 13 essential vitamins in total. These include vitamins A, C, D, E and K. The remaining eight vitamins make up the vitamin B complex that acts as an important building block of a healthy body. These include thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), B6, biotin (B7), folate (B9) and cyanocobalamin (B12).

Vitamins can be found in abundance in plant-based foods like fruits, vegetables, legumes, nuts and grains.

 

Minerals

Much like vitamins, minerals are essential for a number of functions, including bone formation and metabolism. Minerals can also be classified as either a major mineral or a trace mineral.

Major minerals, like magnesium, calcium, phosphorus, sodium and potassium, are those that support bone formation, maintain hydration and support skin health.

Trace minerals, on the other hand, are those needed to regulate blood clots, reduce blood pressure, boost blood circulation and support immune health. Notable trace minerals include iron, selenium, zinc, manganese, copper and iodine.

Minerals can be found in plant-based foods like fruits, salad greens, sea-weeds, grains, beans, legumes, nuts and seeds. That said, some animal products also contain modest amounts of minerals. These include milk, cheese, eggs.

 

Proteins

Protein is the building block of skin, muscles, bones, nails and hair. On top of providing structural support to tissues and organs, protein also aids in forming antibodies, hormones and other essential substances needed for different processes. It also doubles as a fuel source for cells and tissues if needed.

Some of the major sources of protein are eggs and milk. It can also be found in a number of plant-based foods, including beans, legumes, nuts, seeds and some grains.

 

Fats

Fats often get linked to junk foods and bad health, but people forget that not all fats are the same. In fact, the human body needs a certain amount of fat to maintain optimal health, including brain health and joint health. That being said, it’s important to distinguish the good fats from the bad ones.

Good or healthful fats, like monounsaturated and polyunsaturated fats, are those that aid in muscle movement, hormone production, immune response and blood sugar regulation. These can be found in nuts, seeds, coconut oil, olive oil, avocados.

On the other hand, bad fats, like trans fats and saturated fats, are those that raise the risk of heart conditions. Fried and processed foods are abundant in these fats. Steer clear of them as much as possible.

 

Carbohydrates

Carbohydrates are the body’s primary energy source. These nutrients act as fuel for involuntary but important body functions, like the beating of the heart, breathing and digestive processes.

Like fats, there are also good and bad sources of carbohydrates. The good ones are called complex carbohydrates, and they come from whole grains and whole-grain foods, such as quinoa, brown rice, whole-grain pasta, whole-wheat bread and oatmeal.

Bad ones, called simple carbohydrates, are those that come from refined grains and processed grain products, such as white bread, white rice, white flour and white pasta.

 

Water

The body of the average human adult is more than 60% water, according to the United States Geological Survey (USGS). The lungs are composed of the most water at 83%, followed by the brain and the heart at 73%. Even bones hold some amazing percent of water at 31%.

Because it makes up a considerable chunk of various vital organs, even the slightest dehydration can cause side effects, like headaches and fatigue.

On top of keeping the body hydrated, water also helps in flushing out toxins, transporting nutrients and lubricating the joints to keep them flexible.

Although not strictly a nutrient, the Institute of Medicine (IOM) of the National Academy of Sciences (NAS) recommends that adult men should drink at least 13 cups of water every day.

Women should drink a little more than nine cups, and children should drink anywhere between five to 11 cups a day depending on their age group.

 

People need to get all six essential nutrients in order to maintain optimal health. Make sure to drink enough good water (best alkaline water) and to eat healthful, natural, ecological food sources of vitamins, minerals, fats, protein and carbohydrates.

I wish you a radiant health!
