Nutrition and Macronutrients Overview

Study Notes

Nutrition is key to human health and well-being, influencing growth, energy and overall function.
The body takes in and utilizes food, impacting physical performance and mental clarity.
Essential Nutrients include: carbohydrates, proteins, fats, vitamins, minerals, and water.
Balanced nutrition prevents chronic diseases and enhances daily life, enabling a more active and fulfilling life.

Macronutrients are the building blocks of a diet providing the body with energy.
Carbohydrates are made up of sugar molecules and are a primary source of fuel for the brain and muscles.
- Simple Carbohydrates consist of one or two sugar molecules, making them quick to digest and absorb. They provide a rapid source of energy but can lead to spikes in blood sugar levels.
- Complex Carbohydrates are made up of longer chains of sugar molecules, taking more time for the body to break down and digest. They provide sustained energy and are often rich in fiber, vitamins and minerals.
Proteins are the building blocks of your body. Protein helps support every cell, from bone to skin, hair, and muscle. It’s used primarily for growth, health, and body maintenance.
Fats are important compounds that help your body absorb key vitamins and minerals. Although fat is higher in calories than protein and carbs, these calories are an important energy source.
- Unsaturated Fats come from plants and are liquid at room temperature.
- Saturated Fats come from animals and are solid at room temperature.
- Trans Fats are created when liquid oils are turned into solid fats.
