Essential nutrients
Essential nutrients, what are they, and why does the human body need them for the eleven organ systems that ensure a healthy optimal quality of life.
“An essential nutrient is a nutrient required for normal human body function that either cannot be synthesized by the body at all, or cannot be synthesized in amounts adequate for good health (e.g. niacin, choline), and thus must be obtained from a dietary source. Essential nutrients are also defined by the collective physiological evidence for their importance in the diet, as represented in e.g. US government approved tables for Dietary Reference Intake”.

Healthy Diet:
“A healthy diet is one that helps maintain or improve general health. A healthy diet provides the body with essential nutrition: fluid, adequate essential amino acids from protein,[1] essential fatty acids, vitamins, minerals, and adequate calories. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods”.

Essential nutrients
Essential nutrients are compounds that the body can’t make or can’t make in sufficient quantity. According to the World Health OrganizationTrusted Source, these nutrients must come from food, and they’re vital for disease prevention, growth, and good health.
While there are many essential nutrients, they can be broken into two categories: macronutrients and micronutrients.
Macronutrients are eaten in large amounts and include the primary building blocks of your diet — protein, carbohydrates, and fat — which provide your body with energy.
Vitamins and minerals are micronutrients, and small doses go a long way. There are six main groups of essential micronutrients and macronutrients.
