Nutrition

As molecular biology, biochemistry and genetics advance, nutrition has become more focused on the steps of biochemical sequences through which substances inside us and other living organisms are transformed from one form to another - metabolism and metabolic pathways.

Nutrition also focuses on how diseases, conditions, and problems can be prevented or lessened with a healthy diet. Every food must contain one nutrient which makes us the way we are. This one-nutrient myth continued for thousands of years.

 

If you ask any health care professional, be it a doctor, nurse, psychologist, or dentist to identify a part of medicine that is not at all related to nutrition, there will be a long silence as they scratch their heads.

Nutrition is present in all processes of life. Right from the very moment the sperm fertilizes an egg, through fetal development in the uterus, to the birth, human growth, maturity, old age, and eventual death. Even after death, the human body serves as nutrition for other organisms. Anything that involves life and chemical or biochemical movement has nutrition at its core.

Anything that lives is dependent on energy, which results from the combustion of food. The study of nutrients in food, how the body uses nutrients, and the relationship between diet, health, and disease. Major food manufacturers employ nutritionists and food scientists. Nutritionists may also work in journalism, education, and research. Many nutritionists work in the field of food science and technology.

There is a lot of overlap between what nutritionists and dietitians do and study. Some nutritionists work in health care, some dietitians work in the food industry, but a higher percentage of nutritionists work in the food industry and food science and technology, and a higher percentage of dietitians work in health care
