WHAT IS NUTRITION
Ever wonder, what happens to the food you ingest? And how it is advantageous to your body? These questions might have crossed many people’s mind. Well it’s all about eating nutritious foods.
Basically, nutrition is the supply of healthy and wholesome food to the body according to its requirements in order to stay physically and mentally fit. The body has its needs which should be acquired at the right time.
Three things you should keep in your mind:
- Body Requirements
- Excess of Nutrition
Unambiguously, the transformation of food into its nutrients which give a body the energy it needs is termed as Metabolism.
A body needs energy to move, sense, think and everything that it does to work. Metabolism is not just limited to a human body but to every living organism that is alive on the planet, whether it is a plant or an animal or an insect. Simply, it is the basic need of every living body. You must be thinking what if the Metabolism of a body stops? The answer is, it dies.
How It Works
The food is taken by the body in the form of calories or sugar. It is then transformed into energy which is supplied to the body.
Proteins present in the food are broken down into amino acids. 100% of body’s energy is supplied by carbohydrates, proteins, and fats. Proteins are the vital source of energy. Fats are converted into Fatty Acids, which are then converted into energy. Moreover, carbohydrates are converted into calories. The body takes the calories, fatty acids, amino acids etc. and supply them into the blood flowing throughout the body and dispatch them to the tissues, body fat and liver. This is how the body gets its energy.
The amount of specific Nutrients required by the body is called the Nutritional requirements.
Why Nutritional Requirements Exists?
Nutrients have a specific purpose or function in the body and different Nutrients should be in a specific amount. Ups and downs might result in severe detriment to health.
Daily need of Protein intake is 46-56 Grams. 46 Grams for Women and 56 Grams for men.
One cup of Milk has 8 grams of proteins, and a 3-ounce piece of meat contains 21grams of proteins. A simple 8-ounce of meat contain 50 grams and other things contain different amount of proteins.
People of different Age Groups require a specific amount of Protein. Such as Babies need about 10 grams a day, School-age kids need 19-34grams protein a day, Teenage boys 52grams a day, Teenage girls need 46 grams and Adult men need 56grams. Adult Women needs 71grams protein if they are pregnant or breastfeeding.
Excess of Nutrition:
Human body requires specific amount of Nutrition. However, a point comes when the need of nutrition is required no more. At that point, if you ingest more nutrients, the energy diminishes. This is called Excess of Nutrition.
Simple carbohydrates cause insufficiency of energy level and excess usage give rise to system for measuring how quickly different foods allow the sugar they contain to spread into the blood (glycemic index). Saturated fats cause deficiency of vitamin and excess of glycemic index, weight gain, toxicity, metabolism and hyponatremia.
How our body handle excess nutrition?
By extra usage of carbohydrates most of our carbohydrates do not turn into proteins and this amount of carbohydrate causes fats in our body. Mayo clinic claims that we get 45 to 65 percent of daily caloric is intake from carbohydrate. 225 to 325 grams of carbohydrate are handled by our body form adult men and women.
