What is Nutrition? A Comprehensive Introduction.

Introduction:

Nutrition is a very important science as it studies the effect of the food we eat and how it has an impact on our wellbeing, our functions through the nutrients and influences many of health problems, research diseases and how we can protect ourselves from them.

Understanding Nutrition:

 Definition and Scope: Eating is the behavior, nutrition is the science of eating; of eating as a mode of, and a means to, life. It is that complex and delicate way in which we sustain ourselves, studying nutrients — the macronutrients (carbohydrates, proteins, fats) and micronutrients (vitamins, minerals) — as to how they operate in the context of human health and disease.

 Nutrient Functionality: Each nutrient provides a specific health-related function; as such, a healthy diet supplies the components we need to live. Proteins are used for growth and repair of tissue, carbohydrates are the source of fuel that powers our cells, and vitamins and minerals enable myriad different biochemical reactions.

 Dietary Guidelines and Recommendations Organisations like the World Health Organisation (WHO) and national health bodies release dietary guidelines to encourage people to consume a well-balanced and healthy diet. These guidelines often recommend that people eat as varied a diet as possible in order to obtain their recommended nutritional intake.

 Nutrition and health promotion: The human body needs certain nutrients to function properly, and dietary deficiencies can lead to a range of chronic diseases including heart disease, diabetes, obesity, certain cancers and immune system disorders. Adequate nutrition is vital for good immune function and for our general wellbeing and quality of life.

Understanding what nutrients rise from the ground and the ocean, where nature transforms them into foods that our bodies can recognise, is the first big step towards ensuring that your diet is serving your particular health needs and health goals.
