Nutritional

Nutritional science is a field of study that focuses on the effects of food consumption on the human body. It encompasses a broad range of topics, including dietary habits, nutrient absorption, and the role of nutrition in disease prevention and treatment.

Overview

Nutritional science is an interdisciplinary field that draws on many areas of study, including biology, chemistry, and psychology. It seeks to understand how the body uses nutrients and how diet can affect health and wellbeing.

History

The study of nutrition dates back to ancient times, but the science of nutrition as we know it today began to take shape in the 19th and 20th centuries. Early nutritional scientists focused on identifying essential nutrients and understanding their role in health and disease.

Nutrients

Nutrients are substances that the body needs to function properly. They can be divided into two main categories: macronutrients and micronutrients.

Macronutrients

Macronutrients are nutrients that the body needs in large amounts. They include carbohydrates, proteins, and fats.

Micronutrients

Micronutrients are nutrients that the body needs in smaller amounts. They include vitamins and minerals.

Dietary Guidelines

Dietary guidelines are recommendations for healthy eating. They are based on the latest scientific research and are designed to help people make informed food choices.

Nutritional Disorders

Nutritional disorders are health problems that occur when a person's diet does not contain the right amount of nutrients. They can result from both undernutrition and overnutrition.
