Nutrition is a required for human health and development. We know about Essential nutrition for human body. Get a healthy diet throughout life promotes healthy pregnancy outcomes, supports normal growth, development and slow ageing, helps to maintain a healthy human body weight, and reduces the risk of chronic disease (such as diabetes and cardiovascular disease) leading to overall health, well-being and longevity.

The human body contains some chemical compounds such as water, carbohydrates, proteins, lipids (fats), and nucleic acid (DNA and RNA). Therefor, these compounds are composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus. Hence, These compounds are really important essentials nutrients for human body.

Kind Of Essential Nutrition Required For Human Body

Essential nutrition for human body deals with the provision of essential nutrients in food that are necessary to support human life and good health. However, the 7 major causes for nutrients are carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. Essential nutrition can be grouped as either macronutrients (needed in large quantities) or micronutrients (needed in small quantities).

Micronutrients and Macronutrients: explain here

Macronutrients are carbohydrates, fats and protein, and they provide energy. Therefor, Fiber and water are macronutrients but they do not provide energy. Hence, The micronutrients are minerals and vitamins.

The macronutrients (excluding water and fiber) are provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some are the structural material can also be used to generate energy internally. However, Carbohydrates and proteins in human body provide 17 KJ approximately (4 kcal) of energy per gram, while fats provide 37 KJ (9 kcal) per gram, though the net energy from either depends or such factors as digestive effort and absorption, which they vary substantially from instance to instance. Usually, this simple calculation will help you to understand Nutrition required for human body.

Micronutrients and fiber, and water do not provide energy, but are required for other reasons.
Accordingly, Some essential nutrition can be stored – the fat-soluble vitamins – while others are required more or less continuously. However, Poor health can be relates by a lack of required nutrients, or for some vitamins and minerals, too much of a required nutrient. Although Essential nutrition for human body cannot be synthesized by the body, and must be obtained from food.

For all age groups besides, the females no need to consume lower amounts of macronutrients than males. Generally, intakes increase with age until the second or third decade of life.

Malnutrition includes 3 broad groups of conditions:

  • Undernutrition, which includes wasting (low weight-for-height), underweight (low weight-for-age) and stunning (low height-for-age).
  • Malnutrition related micronutrients Hence, which includes micronutrient insufficiencies or deficiencies (a lack of important minerals and vitamins) or micronutrient excess.
  • Obesity, overweight and diet-related non able diseases (such as heart disease, stroke, diabetes and some cancers).

Types of Macronutrients

Calories Starvation: Obesity, diabetes mellitus, cardiovascular disease.
Simple carbohydrate – None Obesity, diabetes mellitus, cardiovascular disease.
Complex carbohydrates: None Obesity, cardiovascular disease (high glycemic index foods).
Protein: Kwashiorkor Obesity, Rabbit starvation.
Saturated fat: – Low testosterone levels, vitamin deficiencies Obesity and cardiovascular disease.
Trans fat: None Obesity, cardiovascular disease.
Unsaturated fat: – Fat soluble vitamin deficiency Obesity as well as cardiovascular disease.

Types of Micronutrients

Vitamin-A: Xerophthalmia, night blindness, and low testosterone levels Hypervitaminosis A (cirrhosis, hair loss)
Vitamin-B1 Beri-Beri?
Vitamin-B2 Skin and corneal lesions, cracking of skin and corneal nucleation?
Niacin Pellagra Dyspepsia, cardiac arrhythmias, birth defects
Biotin Biotin deficiency Reproductive and teratogenic effects

Vitamin-C Scurvy Diarrhea causing dehydration
Vitamin -D Rickets, Hypovitaminosis D, poor immune system function, poor balance, inflammation Hypervitaminosis D (dehydration, vomiting, constipation)
Vitamin-E Neurological disease (anticoagulant: excessive bleeding)
Vitamin-K Hemorrhage Liver damage
Omega-3  Fats Cardiovascular Disease Bleeding, hemorrhages, hemorrhagic stroke, reduced glycemic control among diabetics.
Omega-6 fats None Cardiovascular disease, Cancer
Cholesterol During development – deficiencies in myelinization of the brain; demyelination of the brain and neurodegenerative diseases and cardiovascular disease.

Types of Microminerals

Calcium – Osteoporosis, tetany, carpopedal spasm, laryngospasm, cardiac arrhythmias Fatigue, depression, confusion, nausea, vomiting, constipation, pancreatitis, increased urination, kidney stones and anorexia.
Magnesium:- Hypertension Weakness, vomiting, impaired breathing and hypotension.
Potassium: Hypokalemia, cardiac arrhythmias Hyperkaliemia, palpitations.
Sodium: Hyponatremia, Hypernatremia, hypertension


Therefore, Nutrition education is an important element, these study required for every human being. However, a balanced diet and correct meals are important for a healthy body and healthy mind. Essential Nutrition required for the human body supports boosts immunity and helps the digestive system function. Comment for more nutrition knowledge.
